Developing 3D porous poly(vinyl alcohol) (PVA) scaffolds via gas foaming techniques is often considered a promising strategy in tissue engineering. This study focuses on fabricating PVA scaffolds with advanced porosity and interconnected pore structures, which are crucial for nutrient diffusion and cellular infiltration. Moreover, integrating silver (Ag) nanoparticles (NPs) into these scaffolds via an in situ reduction technique imparted antibacterial properties, further enhancing their tissue-engineering applicability. The gas foaming technique, combined with freeze-drying and alkaline treatment, enables the fabrication of scaffolds without the need for crosslinking agents, thereby safeguarding the biocompatibility of PVA. Additionally, the reaction used to generate gas within the polymer matrix produced calcium carbonate (CaCO3), known for its osteogenic properties. In vitro tests demonstrate that these scaffolds exhibit significant antibacterial properties, effectively inhibiting the growth of pathogens, which is attributed to the presence of Ag NPs, facilitating the release of compounds that combat bacterial colonization. Furthermore, the MTT assay showed that the material was non-toxic to cultured cells. This research underscores the versatility of 3D porous PVA scaffolds as both a structural framework for tissue engineering and a functional material with inherent antibacterial properties, making them suitable for a range of biomedical applications.

Aluminum-doped magnesium ferrite, MgFe2-delta Al delta O4 (where 0 <= delta <= 0.9), nanoparticles were synthesized using a thermal decomposition method with polyvinylpyrrolidone (PVP) as a capping agent. The concentration of the Al dopant was controlled by adjusting the Al-to-Fe precursor ratio. The presence of PVP helps to prevent nano-particle agglomeration. X-ray diffraction (XRD) analysis revealed that lattice constants, cell volume, and porosity varied with Al concentration, confirming the influence of doping on structural properties. The structural, morphological, and magnetic properties of the nanoparticles were thoroughly investigated. XRD confirmed a single-phase ferrite structure. The analysis revealed a decrease in nanocrystalline particle size with increasing Al content, attributed to the structural effects of Al doping. The Nelson-Riley method indicated a reduction in both true and average lattice parameters as Al content increased, which is due to the smaller ionic radius of Al3+ compared to Fe3+ ions. Additionally, bond lengths, hopping lengths, and edge distances at tetrahedral and octahedral sites decreased with Al doping, confirming that structural distortion is linked to ionic substitution and the reduction of lattice constants. The pristine ferrite displayed a distinct nanostructure, whereas the doped samples exhibited increased nanoparticle coalescence. This suggests stronger interparticle interactions leading to the formation of larger aggregates. Magnetic hysteresis loop measurements conducted at room temperature (RT) under a maximum field of 1.8 T demonstrated a decrease in both saturation magnetization (Ms) and remnant magnetization (Mr). These changes were attributed to smaller crystallite sizes, spin canting, and weakened Fe3+-O-Fe3+ interactions caused by the substitution of non-magnetic Al3+ ions. The reduction in magnetic moment occurs when Al3+ replaces Fe3+ at both tetrahedral and octahedral sites, thereby disrupting magnetic sublattice interactions and super-exchange pathways.

The increasing density of wireless and wearable electronic devices necessitates the development of lightweight, flexible, and absorption-dominated electromagnetic interference (EMI) shielding materials. In this study, electrospun poly(vinylidene fluoride) (PVDF) composite mats reinforced with carbon nanotubes (CNTs) and graphene nanosheets at low filler loadings (1-3 wt.%) were fabricated and systematically investigated for X-band (8.0-12.5 GHz) EMI shielding performance. Raman, FTIR, and thermal analyses confirm enhanced electroactive β-phase formation and improved thermal stability upon nanofiller incorporation. The formation of interconnected conductive networks within the electrospun fibrous architecture leads to a significant increase in electrical conductivity from 10-7 S·cm-1 for pure PVDF to 10-2 S·cm-1 and 10-1 S·cm-1 for CNT/PVDF and Graphene/PVDF composites, respectively, at 3 wt.% loading. Consequently, the total EMI shielding effectiveness (SET) increases from 2.5 dB for pure PVDF to 40 dB for CNT/PVDF and 42 dB for graphene/PVDF composites at 3 wt.%. The shielding effectiveness arising from absorption (SEA) dominates the overall EMI shielding performance, contributing more than 85% of the total shielding effectiveness (SET), which clearly indicates an absorption-controlled shielding mechanism. The combination of high absorption-dominated EMI shielding, low filler content, and mechanical flexibility highlights these electrospun CNT/PVDF and graphene/PVDF composites as promising candidates for next-generation flexible, wearable, and biomedical EMI shielding applications.

This study shows that nickel (Ni) doping dramatically improves AlH3's dehydrogenation properties for solid-state hydrogen storage material. While pure AlH3 releases hydrogen at 146 degrees C, ball milling lowers this to 120 degrees C, and 10 wt% Ni doping achieves an even more significant reduction to 80 degrees C while maintaining 9.2 wt% capacity. At 90 degrees C, the Ni-doped sample releases similar to 7.0 wt% hydrogen in 20 min-a significant improvement compared to milled AlH3, which released only 1 wt% hydrogen within the same condition. The Kissinger analysis calculation based on the differential scanning calorimetry confirms the reduction in activation energy for hydrogen release from Ni-doped AlH3 (75.9 kJ/mol) compared to undoped AlH3 (115.9 kJ/mol). The scanning electron microscopy reveals Ni doping enhances particle dispersion and reduces particle size, while X-ray diffraction spectra verify Ni acts catalytically without chemical reaction with AlH3. These improvements stem from Ni's ability to create active sites, shorten diffusion paths, and weaken Al-H bonds through charge transfer effects. Apart from its irreversibility, the combined benefits of lower operating temperature, faster kinetics, and retained capacity position Ni-doped AlH3 as an excellent candidate for practical hydrogen storage applications.

This study focuses on enhancing the wound-healing properties of polyurethane (PU) nanofibers by improving their hydrophilicity, antibacterial activity, and biocompatibility. The nanofibers were fabricated using electrospinning and subsequently coated with titanium dioxide (TiO2) and silver (Ag) nanoparticles (NPs) through a solvothermal treatment using poly(ethylene glycol) (PEG) as a nonaqueous solvent. FE-SEM analysis revealed nanofibers exhibited a rougher texture (yielding more surface area) due to the adsorption of NPs. Furthermore, after 3 min, the water contact angle dropped from 92.84 degrees +/- 6.57 degrees to 7.67 degrees +/- 0.73 degrees for treated nanofibers. The nanofibers were better able to recoup moisture than their pristine counterparts, a necessary criterion for healing. Moreover, the composite mats demonstrated more remarkable thermal stability than pristine nanofibers, with residual weight loss at 700 degrees C being 2.09% for pristine and 24.6% for the composite (7%) nanofibers. The nanofibers were strongly antibacterial compared to the pristine nanofibers, which had no effect. On increasing the concentration of the Ag NPs (7%), the inhibition zones of Escherichia coli were raised from 11.89 +/- 0.66 to 14.83 +/- 1.04 mm, and that of Staphylococcus aureus from 11.45 +/- 0.47 to 14.46 +/- 0.50 mm. Cell studies also showed a substantial increase in growth in composite scaffolds compared to pristine nanofibers. Our research presents unique scaffolds that are excellent for improved wound dressing materials.

An environmentally friendly biodegradable and flexible polymer with exceptional mechanical, thermal and electromagnetic interference shielding is urgently needed to reduce environmental pollutants and electromagnetic waves to preserve human health. The paper presents our study where we developed biodegradable electrospun nanocomposite by employing polybutylene succinate (PBS) with multiwalled carbon nanotubes (MWCNTs). The crystallization temperature Tc and melting temperature Tm of electrospun PBS/MWCNT composites with 3 wt% of MWCNTs was increased noticeably by 4 °C and 5 °C. The tensile strength increased by about 2.61 ± 0.15MPA and the elastic modulus increased by about 0.72 ± 0.02 GPa with the addition of 3% MWCNT in polybutylene succinate. The increase in MWCNT content from 0.5 to 3 wt% led to an enhanced storage modulus and electrical properties 5 to 8 times higher in comparison to PBS. Moreover, the MWCNT was tested in different concentrations in PBS for electromagnetic interference shielding (EMI) and the most applicable results were obtained when the MWCNT was 3% which is capable of providing 25.5 db EMI shielding efficiency. The percolation threshold capability of PBS/MWCNT electrospun nanocomposites was 0.94 wt% and has significant entanglement of the MWCNTs and MWCNT network in the PBS matrix for conductive pathways. The study offers a viable process for creating an electrospun PBS/MWCNT composite that is lightweight, biodegradable and has exceptional electromagnetic shielding capabilities.

This paper investigates the effect of CuFe2O4 as an additive on LiAlH4's dehydrogenation performance. The introduction of CuFe2O4 successfully lowered the initial dehydrogenation temperature of LiAlH4 to 80 degrees C, reducing about 65 degrees C compared to the undoped LiAlH4. The CuFe2O4-doped LiAlH4 sample released hydrogen more quickly than the undoped LiAlH4, releasing 3.1 % of the hydrogen within the first 100 min of heating at a constant temperature of 90 degrees C. For the undoped LiAlH4, the hydrogen desorbed below 0.5 wt% under the same conditions. Using the Kissinger equation, the calculated activation energy for the CuFe2O4-doped LiAlH4 was 30 and 28 kJ/mol lower than that of milled LiAlH4 for the first two steps of decomposition. The scanning electron microscope images revealed that the addition of CuFe2O4 reduced the particle size of LiAlH4. The Fe, LiFeO2, and amorphous Cu or Cu-containing species that were generated in situ during the dehydrogenation process are thought to have a crucial impact on the dehydrogenation properties of LiAlH4.

An alarming elevation of anthropogenic carbon dioxide (CO 2 ), primarily responsible for global warming and its drastic effects on climatic conditions, must be challenged on a priority basis. Various types of absorbents capture as much CO 2 as possible to minimize the harsh effects of environmental and climatic changes. In this study, one such compound, methyltrioctylammonium trifluoromethanesulfonate ionic liquid (IL), was analyzed experimentally and theoretically. The COSMO‐RS, a type of conductor‐like screening model, is an advanced fast method to predict the thermo‐physical properties of IL. It depends upon unimolecular, statistical thermodynamics, molecular structure, and conformation, which provides the required information for estimating interactions in ILs. The COSMO‐RS, not dependent on data, coefficients, or parameters, was used to calculate the sigma surface, profile, and potential. These parameters are crucial for predicting high‐absorbing CO 2 materials, such as ILILs. Spectroscopic methods, such as Fourier transform infrared spectroscopy (FTIR), proton nuclear magnetic resonance ( 1 H NMR), and carbon‐13 NMR ( 13 C NMR), verified the structure confirmation. In addition, spectrochemical characterization of the IL was performed using FTIR, NMR, ultraviolet–visible (UV–Vis) spectroscopy, and fluorescence. The thermal integrity of IL was measured by thermogravimetric–differential thermal analysis (TGA‐DTA) over the temperature range of 323–773 K in an oxygen ambiance with a ramp rate of 283 K/min. Due to its high potential for gas absorption, as confirmed by COSMO‐RS calculations, IL was investigated for CO 2 absorption and desorption studies at 298 K and 4.5 MPa. The maximum CO 2 absorption obtained was ~ 6.0 mmol/g, performed at similar experimental conditions. The high uptake of CO 2 might be due to fluorinated anions, as CO 2 has a high affinity for fluoroalkyl groups. According to a hysteresis‐based classification, the hysteresis formation during CO 2 absorption and desorption follows type H3, indicating the presence of both microporous and mesoporous characteristics in the sample. A detailed study of the excess Gibbs energy of sorption and the activity coefficient of the IL indicates a strong sorption capacity under moderate conditions.

Techniques like extractive distillation and pressure swing distillation (PSD) have been commercially developed to separate azeotropic mixtures. Extractive distillation using conventional solvents offers advantages in achieving high purity levels, but challenges include difficulty in solvent recovery, increased energy consumption, higher costs, and potential negative environmental impact. Selecting appropriate solvents is a challenging task with potential compromises. PSD manipulates pressure to overcome azeotropic points without an entrainer, offering solvent-free operation. Ionic liquids may provide an alternative to conventional solvents in extractive distillation. Five imidazolium, ammonium and pyridinium based ILs have been chosen to investigate their impact on the separation of the selected azeotropic mixtures. The three techniques are employed for seven different (model) azeotropic mixtures to evaluate the commercial feasibility of each process by comparing energy requirements and Total Annual Cost (TAC). Aspen Plus software has been employed to perform a comparison simulation among the processes. This benchmark analysis and process simulation can aid in evaluating the efficacy and feasibility of the possible optimum commercial process in separation. There is no one-size-fits-all technique that provides the best cost-effective and energy-efficient process for every azeotropic separation.

This work presents a hybrid material composed of a physically cross‐linked poly(vinyl alcohol)/chitosan hydrogel with a pore size of 35 ± 10 nm loaded with silver (Ag) nanoparticles (NPs) with a diameter of 83.4 nm. This hydrogel is physically integrated with polyurethane (PU) nanofibers with an average diameter of 0.93 ± 0.5 μm that is preloaded with silk fibroin (SF)‐encapsulated zoledronic acid (ZA) NPs (99.11 nm). However, the hybrid composites are hydrophilic, showing contact angles of <90 o due to incorporating hydrogel and NPs. Ultraviolet‐visible spectrophotometry demonstrates a burst release of ZA from SF NPs within the first 6 h, followed by sustained release up to 48 h, after which the release rate declined. The degradation of hybrid composites in phosphate‐buffered saline (PBS), protease type XIV, and human plasmin shows an increased degradation in the enzyme solutions of protease type XIV (42.6 ± 1.4%) and plasmin (52.6 ± 1.1%) than PBS (27.5 ± 1.9%) after 40 days. Biocompatibility is assessed using 3‐(4,5‐dimethylthiazol‐2‐yl)‐2,5‐diphenyl tetrazolium bromide and staining, revealing viability of >300% and a higher cell density than the pure PU scaffold. These results suggest that the composite scaffolds offer a highly effective release of loaded NPs are suitable for healthcare products and devices for tissue engineering applications, especially deep wound defects involving bone injuries.

The second most prevalent cause of mortality among women is breast cancer, and paclitaxel (PTX) is an effective drug for its treatment. The present work aims to develop patch-based poly(ε-caprolactone) (PCL) nanofibers incorporating PTX as a localized and sustained drug delivery system. The co-deposition of poly(vinyl alcohol) (PVA) fibers during electrospinning was allowed to improve water absorption by the scaffold, which in turn facilitated the release of drug molecules. To figure out optimized electrospinning parameters and predict the optimal formulation, the quality-by-design approach was utilized. The blank mat, i.e., without drug and optimized nanofiber formulation (Fo), was characterized physiochemically using FE-SEM, XRD, FT-IR, TGA and DSC techniques. The optimization yielded a 92.7 % final product yield, indicating high process efficiency and minimum losses during electrospinning. FE-SEM studies have demonstrated that uniform nanofibers with bead-free morphology. The average fiber diameter and drug entrapment of the optimal formulation, Fo, were 547 ± 6.6 nm and 85 ± 1.73 %, respectively. Diffraction and calorimetric studies revealed a sharp decrease in the crystallinity of pure PTX and its subsequent amorphization within the nanofiber matrix. FT-IR studies showed no chemical interaction between the drug and polymers. A decrease in water contact angle from 120.4 ± 0.9 to 81.0 ± 0.8 in the Fo formulation was due to the co-spinning of PVA; this ensures proper wettability and adhesion ideal for localized delivery. The Fo nanofiber formulation demonstrated sustained PTX release for up to 17 days. The MTT assay results confirm Fo nanofibers were cytotoxic to the breast cancer cell line, MDA-MB-231, than pristine nanofibers. These findings suggest that Fo nanofiber mats could be a potential localized delivery system for PTX in breast cancer treatment, pending further in-vivo validation.

Isoreticular metal–organic frameworks (IRMOFs) prepared by various methods engaging conventional costly organic solvents and precursor materials incorporate different challenges including production cost, energy, and toxicity. The environmentally friendly solvent particularly water nullifies the disadvantages occurred by hazardous solvents and provides stability, cheap production, minimal energy, disposability, and more important zero pollution. The organic solvent elimination from pores, cavities, and channels is laborious work as compared to the use of water as a solvent for the synthesis of different types of IRMOFs. The structural, thermal, and mechanical stability and other improved characteristics were found in the water-based IRMOFs. The different types of preparation methods such as microwave irradiation, ultrasound-assisted, microwave-assisted solvothermal, and in situ growth utilized for toxic-free IRMOFs. The IRMOFs, an extended version of MOFs surface is an important material for various types of applications because of its ultrahigh surface area, elevated pore volume, pore tenability, and topology. The elevated specific surface area, high pore volume, and cage-like framework make IRMOFs the best adsorbent/absorbent for different types of gases such as CO2, hydrogen, benzene, sulfur dioxide, ammonia, chlorine, dichloromethane, and ethylene dioxide. The two main applications including hydrogen adsorption and CO2 capture in porous IRMOFs are very crucial according to low cost and environmental friendliness when used for on-board and other applications. The IRMOFs without modification show very low hydrogen storage capacity at moderate conditions, however, post modification many folds enhancement was found.

For the first time, the MgH2–NaAlH4 (ratio 4:1) destabilized system with CoTiO3 addition has been explored. The CoTiO3-doped MgH2–NaAlH4 sample begins to dehydrogenate at 130 °C, which is declined by 40 °C compared to the undoped MgH2–NaAlH4. Moreover, the de/rehydrogenation kinetics characteristics of the CoTiO3-doped MgH2–NaAlH4 were greatly ameliorated. With the inclusion of CoTiO3, the MgH2–NaAlH4 composite absorbed 5.2 wt.% H2, higher than undoped MgH2–NaAlH4. In the context of dehydrogenation, the CoTiO3-doped MgH2–NaAlH4 sample desorbed 2.6 wt.% H2, almost doubled compared to the amount of hydrogen desorbed from the undoped MgH2–NaAlH4 sample. The activation energy obtained by the Kissinger analysis for MgH2 decomposition was significantly lower by 35.9 kJ/mol than the undoped MgH2–NaAlH4 sample. The reaction mechanism demonstrated that new phases of MgCo and AlTi3 were generated in situ during the heating process and are likely to play a substantial catalytic function and be useful in ameliorating the de/rehydrogenation properties of the destabilized MgH2–NaAlH4 system with the inclusion of CoTiO3.

Nowadays, the solvothermal approach to modify as-spun nanofibers has gained attention. This technique involves subjecting nanofibers to a reaction environment with high temperature and pressure in the presence of a nonsolvent while preserving the fiber architect. This review emphasizes that desirable morphological changes can be brought to the nanofiber surface to achieve the properties by adjusting the solvent concentration and other reaction parameters, such as temperature, pressure, and the addition of functional groups. This article indicates that post-modification can lead to customized characteristics that will help to improve the nanofibers' performance in applications such as photocatalysis, sensing, energy storage, and biomedical areas. After the solvothermal treatment, these post-modified nanofibers have shown excellent reusability, visible light photocatalytic nature < 90% dye removal property, high-capacitive character, enhanced gas sensing ability, and antibacterial activity. However, the reaction conditions during the solvothermal process to as-spun nanofibers must be controlled to meet the latest advancement needs precisely.

Capturing carbon dioxide is vital for mitigating global warming and supporting chemical processes. Ionic liquids (ILs) have emerged as promising solvents for CO2 capture. Using ASPEN simulation software, this study explores three specific ILs: [emim][triflate], [bmim][MeSO3], and [bmim][NTf2]. Their selection is based on exploitable differences in energy. The study models CO2 solubility and validates it against published data. It also considers the decomposition of ILs using a more accurate vapor loss model. Simulated equations predict CO2 and IL behavior more accurately than published ASPEN studies, optimizing the process for minimal energy consumption. Commercial considerations and rigorous engineering calculations guide the analysis, encompassing energy and economic factors.

Different wounds take a while to heal, and the process is frequently accompanied by bacterial infection and scar formation. This study aimed to fabricate polyurethane (PU) fibers through electrospinning, utilizing a mixture of THF and DMF solvents in a 90:10 ratio. Subsequently, these fibers were coated with different concentrations of hyaluronic acid (HA) and silver (Ag) nanoparticles (NPs) using the hydrothermal treatment to create biocompatible and antibacterial scaffolds applicable to wound management. Pristine samples served as a basis for comparison. Following high-temperature usage during the hydrothermal coating, the Field emission scanning electron microscopy (FE-SEM) results showed defect-free morphology. However, the fibers’ diameter significantly increased by layer of HA. In particular, the diameter of the PU fibers was 1.87 ± 1.1 µm, whereas the fibers with the maximum amount of HA (0.5

Due to its high gravimetric capacity of hydrogen (10.5 wt.%), LiAlH4 has been regarded as a promising material for solid-state hydrogen storage material for onboard usage. However, high decomposition temperature, poor kinetics and irreversibility retard its application. To counter this problem, various weight percentages of BaMnO3 are introduced into the LiAlH4 system as an additive in this work. As a result, the starting hydrogen release of LiAlH4 was reduced to 109−115 °C and the second desorption temperature occurred at around 134−158 °C, much lower than pure LiAlH4. The isothermal desorption kinetics also proved that faster desorption kinetics can be observed at 90 °C for 80 min. About 2.00−2.60 wt.% of H2 could be desorbed by the composite, whereas only <1.00 wt.% of H2 was desorbed by undoped LiAlH4. Additionally, adding BaMnO3 reduced the activation energies by 30 kJ/mol for the first stages and 34 kJ/mol for the second stages. Based on the X-ray diffraction result, the active species formed of MnO2 and Ba or Ba−containing materials are believed to be responsible for the noticeable enhancement in the desorption properties of LiAlH4.

The microalgae have a great potential as the fourth generation biofuel feedstock to deal with energy crisis, but the cost of production and biomass harvest are the major hurdles in terms of large scale production and applications. Using filamentous fungi to culture targeted alga for biomass accumulation and eventually harvesting is a sustainable way to mitigate environmental impacts. Microalgal co-culture method could be an alternative to overcome limitations and increase biomass yield and lipid accumulation. It was found to be the high feasibility for the production of biofuels from fungi and microalgae using wastewater. This article aimed to state the synergistic approaches, their culture protocols, harvesting procedure and their potential biotechnological applications. Additionally, algal-fungal consortia could digest cellulosic biomass, potentially reducing operating costs as part of industrial need. As a result of co-cultivation, biofuel production could be economically feasible owing to its excellent ability to treat wastewater and be eco-friendly. The implications of the innovative co-cultivation technology have demonstrated the potential for further development based on the policies that have been supported and implemented.

In general, sludge wastewater treatments from plants are often disposed of in landfills (60%) rather than recycled, and this eventually affects the environment. Microalgae cultivation in wastewater has recently emerged as an alternate method for successfully treating wastewater in an ecofriendly way. The present study explores the possibility of growing microalgae in sludge effluent derived from industries. Industrial sludge acts as the only nutritional supplement for algal growth. The amount of organic carbon might increase the amount of protein and carbohydrates used for the production of lipids. The batch culture of different ratios of sludge wastewater was compared. The features of algal growth and biodiesel generation were studied, as well as the nitrogen and phosphate removal rates. The lipid levels of Chlorella sp. produced in this medium were clearly superior to those grown on the BG11 medium. Furthermore, this study indicated that the removal of industrial sludge and wastewater, in the absence of other nutritional supplies, allows for an efficient culture of Chlorella sp., followed by biodiesel generation. This has significant research and industrial implications since it will enable Chlorella sp. production in a mixed waste culture medium without the need for additional nutritional sources.

The high hydrogen storage capacity (10.5 wt.%) and release of hydrogen at a moderate temperature make LiAlH4 an appealing material for hydrogen storage. However, LiAlH4 suffers from slow kinetics and irreversibility. Hence, LaCoO3 was selected as an additive to defeat the slow kinetics problems of LiAlH4. For the irreversibility part, it still required high pressure to absorb hydrogen. Thus, this study focused on the reduction of the onset desorption temperature and the quickening of the desorption kinetics of LiAlH4. Here, we report the different weight percentages of LaCoO3 mixed with LiAlH4 using the ball-milling method. Interestingly, the addition of 10 wt.% of LaCoO3 resulted in a decrease in the desorption temperature to 70 °C for the first stage and 156 °C for the second stage. In addition, at 90 °C, LiAlH4 + 10 wt.% LaCoO3 can desorb 3.37 wt.% of H2 in 80 min, which is 10 times faster than the unsubstituted samples. The activation energies values for this composite are greatly reduced to 71 kJ/mol for the first stages and 95 kJ/mol for the second stages compared to milled LiAlH4 (107 kJ/mol and 120 kJ/mol for the first two stages, respectively). The enhancement of hydrogen desorption kinetics of LiAlH4 is attributed to the in situ formation of AlCo and La or La-containing species in the presence of LaCoO3, which resulted in a reduction of the onset desorption temperature and activation energies of LiAlH4.
