In this study, nickel ferrite/polypyrrole composites were synthesized through in-situ oxidative polymerization to analyze their applicability as an electrode material for supercapacitors. The structural, morphological, and electrochemical properties of the synthesized material have been thoroughly investigated. The electrochemical characterizations have shown that the N5PY5 (50-50 wt%) composite of nickel ferrite and polypyrrole has a specific capacitance of 503.3 F/g at 2 A/g in 6 M KOH, which is three times higher than pure nickel ferrite. The value of solution resistance and charge transfer resistance is also reduced for the composite in comparison to pure nickel ferrite. The enhanced electrochemical performance of the composite electrode was explained on the basis of the synergistic effect between the polypyrrole and nickel ferrite. Polypyrrole acts as a conductive support, provides additional active sites, and improves redox activity and diffusion in the composite electrode. Theoretical analysis using DFT calculation was also employed to analyze the interaction mechanism between the polypyrrole and nickel ferrite. The high adsorption energy (-2.6 eV) and covalent bonding between oxygen and carbon indicated a strong interaction between the nickel ferrite and pyrrole's dimer. Consequently, the composite electrode shows improved stability (88.6 %) as compared to polypyrrole (38.6 %) after 1000 cycles of charging and discharging.
Density functional theory (DFT) was used to analyze the adsorption mechanism of greenhouse gases (CO2, CH4, NF3, and N2O) on pristine, palladium-doped, and boron/palladium co-doped graphitic carbon nitride. It is shown that gases adsorbed on the pristine graphitic carbon nitride surface exhibit weak interaction, while the doped system shows stronger adsorption for most of the gases. The findings from density of states, projected density of states, change in band gap, and charge transfer analysis demonstrate that the incorporation of palladium and boron-palladium atoms substantially improves the adsorption capacity of the graphitic carbon nitride monolayer for various greenhouse gases, with adsorption energies varying from-0.06 eV to-6.21 eV. Both doped monolayers also have the charge transfer range from-0.01 |e| to-1.27 |e|. Most of the transferred charges are accumulated at the lower unoccupied molecular orbital of greenhouse gases. A higher amount of charge transfer also leads to deformation of the gas geometry. Therefore, the palladium-doped graphitic carbon nitride mono-layer can be regarded as a potential resistive gas sensor for CO2, NF3, and N2O gases, while the high adsorption energy and charge transfer for boron-palladium-doped graphitic carbon nitride make it a potential candidate for a one-time sensor or a scavenger.

This study presents comprehensive preformulation investigations of Ibudilast, a phosphodiesterase inhibitor with therapeutic applications in bronchial asthma, cerebrovascular disorders, multiple sclerosis, and substance use disorders. The research aimed to establish a scientific foundation for rational formulation development by systematically characterizing Ibudilast's physicochemical properties. Organoleptic evaluation confirmed Ibudilast as a white, odorless, bitter, crystalline powder. FT-IR spectroscopy validated the drug's identity through characteristic absorption bands at 3083 cm⁻¹ (aromatic C-H), 2959 cm⁻¹ (aliphatic C-H), 1640 cm⁻¹ (C=O carbonyl), and 1538 cm⁻¹ (aromatic C=C/C=N), confirming the pyrazolopyridine ring structure with isopropyl and isobutyryl substituents. UV spectrophotometry established λmax at 227 nm in methanol. The melting point was determined to be 58-62°C, with slight deviation from literature values (54-58°C), confirming drug purity. Miscibility studies revealed poor water miscibility with complete dissolution in methanol and ethanol within 2-4 minutes. Micromeritic evaluation demonstrated passable flow properties with Carr's Index of 23.19 ± 1.24%, Hausner's Ratio of 1.30 ± 0.04, and angle of repose of 36.45 ± 1.82°. FT-IR compatibility studies with bovine serum albumin demonstrated no chemical incompatibility with only minimal peak shifts (2-4 cm⁻¹), indicating weak physical interactions and confirming BSA's suitability as a carrier for nanoparticle formulation. Optical microscopy revealed irregular crystalline particles with a mean size of 48.35 ± 12.67 μm, suggesting potential benefits from particle size reduction strategies. These comprehensive preformulation data provide essential insights for developing optimized Ibudilast formulations with enhanced bioavailability and therapeutic efficacy.
Globally, the use of solar energy has increased due to the rising demand for clean electricity and falling photovoltaic (PV) costs. Nevertheless, the extensive integration of photovoltaic systems into power networks presents numerous technological hurdles stemming from intermittency, restricted predictability, and inverter-dependent functioning. These challenges encompass voltage elevation, reverse power flow, frequency instability, power quality issues, auxiliary service demands, and heightened flexibility requirements. This paper provides a brief overview of the primary technical difficulties related to high PV integration, such as voltage increases, reverse power flow, frequency instability, power quality degradation, and increasing ancillary service requirements. Recent mitigation measures, including smart inverter control, energy storage systems, grid stabilisation, and advanced protective mechanisms, are presented. A comprehensive evaluation strategy is employed, categorizing the obstacles according to voltage, protection, frequency, and power quality concerns. A thorough analysis of the various challenges the existing solutions of high solar photovoltaic integration on power system is also discussed. Recent mitigation measures, including smart inverter functionalities, energy storage systems, network enhancement, and sophisticated control methodologies, are examined.
