Fabrication and Evaluation of Polycaprolactone/Gelatin‐Based Electrospun Nanofibers with Antibacterial Properties
Nanofibrous scaffolds were fabricated through blending of a synthetic polymer, polycaprolactone (PCL), and a natural polymer, gelatin (GE), using an electrospinning technique. Processing and solution parameters were optimized to determine the suitable properties of PCL/GE‐based nanofibers. Several characterizations we…

RGO reinforced polymer composites with significantly enhanced nanomechanical properties useful for automobile, wind mill blade industries and also in hard and scratch-less coatings on automotive vehicles have been synthesized.
Diffusion of molecules in the bulk of a low density amorphous ice from molecular dynamics simulations
The diffusion of molecules in interstellar ice is a fundamental phenomenon to take into account while studying the formation of complex molecules in this ice. This work presents a theoretical study on the diffusion of H2O, NH3, CO2, CO, and H2CO in the bulk of a low density amorphous (LDA) ice, while taking into accou…
Hydrogen bonded and ionically crosslinked high strength hydrogels exhibiting Ca 2+ -triggered shape memory properties and volume shrinkage for cell detachment
-induced marked variation in mechanotransduction between the cells and the substrate interface. This H-bonding and ionic crosslinking strategy opens up a new opportunity for designing and constructing multifunctional high strength hydrogels for biomedical applications.
Nonradiative energy transfer in colloidal CdSe nanoplatelet films
Nonradiative energy transfer (NRET) has been extensively studied in colloidal nanocrystal (quantum dots) and nanorod (quantum wires) assemblies. In this work, we present the first account of spectroscopic evidence of NRET in solid thin films of CdSe based colloidal nanoplatelets (NPLs), also known as colloidal quantum…
Remarkable enhancement in photocytotoxicity and hydrolytic stability of curcumin on binding to an oxovanadium( iv ) moiety
Oxovanadium(IV) complexes of polypyridyl and curcumin-based ligands, viz. [VO(cur)(L)Cl] (1, 2) and [VO(scur)(L)Cl] (3, 4), where L is 1,10-phenanthroline (phen in 1 and 3), dipyrido[3,2-a:2',3'-c]phenazine (dppz in 2 and 4), Hcur is curcumin and Hscur is diglucosylcurcumin, were synthesized and characterized and thei…
