Reversible, carbon dioxide mediated chemical hydrogen storage was first demonstrated using a heterogeneous Pd catalyst supported on mesoporous graphitic nitride (Pd/mpg-C3N4). The nanoparticles were found to be uniformly dispersed onto mpg-C3N4 with an average size of 1.7 nm without any agglomeration and further exhibit superior activity for the dehydrogenation formic acid turnover frequency 144 h−1 even in absence external bases at room temperature. Initial DFT studies suggest that basic...
The need for advancement in biomaterials that stimulate the repair, replacement, or recovery of gentle body tissues and bones keeps growing as population ages. Although substantial research has been carried out over last decade to develop medical implants bone regeneration healing tissues, still fail due infection, fracture, corrosion, extreme load. Depending upon permanent temporary implant requirement, various materials such metals, ceramics, polymers are used implantable materials....
An explicit study of comparison on the basis structure and electronic properties ZnO nanostructures was discussed. synthesized by sol-gel hydrothermal method without using any surfactant leads to formation two different morphologies. Rietveld crystal refinement X-ray diffraction patterns confirmed wurtzite both samples. Raman spectra also phase improved crystallinity in sample route that are concurrent with results obtained from diffraction. Field-emission scanning electron microscopy...
In Pt-transition metal (TM) alloy catalysts, the electron transfer from TM to Pt is retarded owing inevitable oxidation of surface by oxygen. addition, acidic electrolytes such as those employed in fuel cells accelerate dissolution oxide, which leads catalyst degradation. Herein, we propose a novel synthesis strategy that selectively modifies electronic structure Co atoms with N-containing polymers, resulting highly active and durable PtCo nanoparticle catalysts useful for oxygen reduction...
Carrier dynamics affects photocatalytic systems, but direct and real-time observations in an element-specific energy-level-specific manner are challenging. In this study, we demonstrate that the of photo-generated holes metal oxides can be directly probed by using femtosecond X-ray absorption spectroscopy at free-electron laser. We identify energy level life time with a long (230 pico-seconds) nano-crystal materials. also observe trapped show distribution bandgap region formation 0.3...
Targeted drug delivery using metal-organic frameworks (MOFs) has become an area of significant interest due to their unique ability change configuration and porosity. MOFs offer a tuneable porous hybridization that enhances interactions allows for greater loadings. The drugs are enclosed within nanoparticles designed protect them against enzymatic chemical degradation, ensuring targeted specific locations with precise dosages. This technology demonstrated immense potential revolutionize...
Hydroxyapatite (HAp) with the chemical formula Ca10(PO4)6(OH)2 is an inorganic material that exhibits morphology and composition similar to those of human bone tissues, making it highly desirable for regeneration applications. As one most biocompatible materials currently in use, HAp has undergone numerous attempts enhance its mechanical strength. This research focuses on investigating influence magnesium (Mg) incorporation structural properties synthesized magnesium-doped hydroxyapatite...
We report on the synthesis of Fe-doped ZnO with nominal composition Zn0.99Fe0.01O by using a coprecipitation method. X-ray diffraction and selective area electron studies reveal single phase wurtzite crystal structure without any secondary phase. Field emission transmission microscopy measurements infer that have nanorod-type microstructures. Magnetic hysteresis measurement performed at different temperatures show exhibits weak ferromagnetic behavior room temperature. A detailed...

The surface morphology these was investigated scanning electron microscopy shows presence randomly distributed structures nanorods. Grazing angle x-ray diffraction studies confirm that ions occupied Zn sites samples exhibited a wurtzite hexagonal-like crystal structure similar to parent compound, ZnO. micro-photoluminescence measurement decrease in near band edge...
Au nanoparticles (NPs) on the surface and embedded in a matrix have been subject of studies dealing with variety spectroscopic sensing applications.
We synthesized a series of acceptor-donor-acceptor-type small molecules (SIDPP-EE, SIDPP-EO, SIDPP-OE, and SIDPP-OO) consisting dithienosilole (SI) electron-donating moiety two diketopyrrolopyrrole (DPP) electron-withdrawing moieties each bearing linear n-octyl (O) and/or branched 2-ethylhexyl (E) alkyl side chains. X-ray diffraction patterns revealed that SIDPP-EE SIDPP-EO films were highly crystalline with pronounced edge-on orientation, whereas SIDPP-OE SIDPP-OO less radial distribution...
Thioamides are used as potential surrogates of amides to study the structure and dynamics proteins nucleic acids. However, incorporation thioamides in biomolecules leads changes their structures conformations mostly attributed strength amide-N-H···S═C hydrogen bond. In most cases, it is considered weak owing small electronegativity sulfur, some strong conventional H-bonds. Herein, adopting PDB analysis, NMR spectroscopy, quantum chemistry calculations, we have shown that a geometrical...
