Emerging nanotechnologies in wound care: The role of metal and polymeric nanocomposites in enhancing healing and combating infections.

Chronic wounds are a foremost cause of death, affecting 6.5 million people annually. Traditional treatments, such as metal-based formulations and biomaterials, are ineffective due to their toxicity and the rising incidence of chronic wound cases, necessitating the advancement of new therapies for efficient wound healing.

Anion Exchange Membranes with Tuned Hydrophilic-Hydrophobic Phase Separation for Efficient Ion Transportation.

Study of the Crystal Architecture, Optoelectronic Characteristics, and Nonlinear Optical Properties of 4-Amino Antipyrine Schiff Bases.

Two Schiff bases, ()-4-((2-chlorobenzylidene)amino)-1,5-dimethyl-2-phenyl-1,2-dihydro-3-pyrazol-3-one (4AAPOCB) and ()-4-((4-chlorobenzylidene)amino)-1,5-dimethyl-2-phenyl-1,2-dihydro-3-pyrazol-3-one (4AAPPCB), have been synthesized and grown as single crystals. Single-crystal X-ray diffraction analysis was employed to determine the crystal structure of the compounds, and the results suggest that the compounds crystallized into an orthorhombic crystal system having 222 and space groups, respectively. Further, the crystallinity of the compounds was analyzed by the PXRD technique.
