Dexterous semi-organic Glycine doped Copper Sulphate (GDCS) single crystal was produced by slow evaporation solution growth method. Single crystal X-ray diffraction studies were used to authorize the crystal structure. It shows that the grown GDCS crystal belongs to the space group P1 with a triclinic crystal system and the found lattice parameters are a = 5.9758(14) Å, b = 6.1295(15) Å, c = 10.751(3) Å, α = 77.446(8) °, β = 82.358(8) °, γ = 72.691(7) °, volume = 365.99(15) Å3. The interaction of characteristic functional groups was approved by FTIR and FT-Raman spectra. The optical properties were studied by UV–Vis-NIR and fluorescence analyses. The optical parameters such as optical band gap (4.33 eV), Urbach energy (4.971414 eV), steepness parameter. (4.7321 × 10–3) and electron–phonon interaction (1.4088178 × 102) were calculated. The observation of maximum intensity peak for the GDCS crystal at 545 nm pointed out green fluorescence emission. The third-order nonlinear optical properties of the synthesized crystal were analysed using the Z-scan technique. The third-order nonlinear optical parameters of GDCS single crystal such as absorption coefficient, nonlinear refractive index, third-order nonlinear optical susceptibility and second-order molecular hyperpolarizability have been computed. The result shows that the grown GDCS single crystal may be used for applications of holographic recording and two-wave mixing. The thermal lenience and decomposition mechanism of the grown compound was examined by simultaneous TG–DTA analysis. The kinetic parameters such as activation energy, frequency factor, entropy, enthalpy and Gibbs free energy were calculated using Coats–Redfern method. The dielectric characteristics of the synthesized crystal was studied by dielectric analysis. The dielectric parameters of the grown crystal such as plasma energy (18.656 eV), Penn gap (4.2042 eV), Fermi energy (14.5865 eV) and electronic polarizability have been calculated. The crystalline morphology was inspected by SEM analysis. It was noted from the SEM images that the surface of the produced crystal is smooth and contains of uniformly dispersed clusters. Its elemental composition was confirmed by EDAX analysis. In the EDAX spectrum, the occurrence of Cu, S and O intense peaks confirm the presence of copper, sulphur and oxygen in the grown GDCS single crystal respectively. The antibacterial activity of GDCS crystal against strains Pseudomonas aeruginosa, Serratia marcens and Staphylococcus aureus have been analysed. The antifungal activity of the sample against strains Candida albicans, Aspergillus niger and Aspergillus flaves were tested.
The mesoporous iron-doped MCM-41 material was synthesized by adding iron species into the oil-template-derived MCM-41 framework through an impregnation method. The prepared Fe-MCM-41 had the surface area of 357.974 m2/g. with pore diameter of 3.81 nm. The characterization of synthesized Fe-MCM-41 through powder x-ray diffraction, Fourier infrared, scanning electron microscope with energy dispersive spectroscopy revealed the entry of Fe-species without altering the MCM-41 framework. Optical energy bandgap was measured as 3.72 eV using the result of UV–visible spectroscopy. Electrochemical performance was evaluated using cyclic voltammetry (CV) and galvanostatic charge/discharge (GCD) in a 6 M KOH electrolyte within a potential window of -0.9—0.1 V. The prepared electrode material exhibited 99
We present 3D Points Splatting Hand Reconstruction (3D-PSHR), a real-time and photo-realistic hand reconstruction approach. We propose a self-adaptive canonical points upsampling strategy to achieve high-resolution hand geometry representation. This is followed by a self-adaptive deformation that deforms the hand from the canonical space to the target pose, adapting to the dynamic changing of canonical points which, in contrast to the common practice of subdividing the MANO model, offers greater flexibility and results in improved geometry fitting. To model texture, we disentangle the appearance color into the intrinsic albedo and pose-aware shading, which are learned through a Context-Attention module. Moreover, our approach allows the geometric and the appearance models to be trained simultaneously in an end-to-end manner. We demonstrate that our method is capable of producing animatable, photorealistic and relightable hand reconstructions using multiple datasets, including monocular videos captured with handheld smartphones and large-scale multi-view videos featuring various hand poses. We also demonstrate that our approach achieves real-time rendering speeds while simultaneously maintaining superior performance compared to existing state-of-the-art methods.
The present investigation assessed the levels of cadmium (Cd), chromium (Cr), lead (Pb), and nickel (Ni) in five popular brands of cigarettes that are commonly consumed in India. Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) was used to evaluate the samples. The concentrations of Cd, Cr, Pb, Ni, and As in the filler tobacco of cigarettes were 0.078 ± 0.024, 0.152 ± 0.017, 0.2512 ± 0.161, 0.178 ± 0.011, and 0.003 ± 0 μg/g, respectively, obtained from 0.5 g of tobacco from sample cigarettes C1, C2, C3, C4, and C5. This study’s results indicated that heavy metal concentrations followed the trend Pb > Ni > Cr > Cd > As. Cd showed a strong positive correlation with Pb (r = 0.965), while it also exhibited a strong negative correlation with Cr (r = − 0.287). The overall outcomes of the non-carcinogenic risk assessment (Hazard Quotient, HQ) for children and adults revealed that Cd, followed by Pb, posed a higher risk via the ingestion pathway compared to both pathways combined. Specifically, Cd and Pb posed non-carcinogenic risks for children and adults through ingestion, with HQ values exceeding 1.0 (Hazard Index > 1). In the overall results of the cancerous risk assessment of children and adults, when comparing both pathways, these heavy metals can cause highly carcinogenic risks from tobacco cigarettes through the inhalation pathway rather than the ingestion pathway. The results indicated that the tobacco contained heavy metals, presenting a significant potential health risk to users.
