There is a continuous and pressing need to establish new brain-penetrant bioactive compounds with anti-cancer properties. To this end, series of 4'-((4-substituted-4,5-dihydro-1H-1,2,3-triazol-1-yl)methyl)-[1,1'-biphenyl]-2-carbonitrile (OTBN-1,2,3-triazole) derivatives were synthesized by click chemistry. The designed from diverse alkynes N
Herein, a fully sustainable, flexible, and bio-based piezoelectric-cum-triboelectric energy harvester has been developed using simple commodity cotton fabric. In the present study, novel attempt made to prepare piezoelectric triboelectric in combined manner from same fabric substrate. The mercerized fabric-based shown significant open-circuit peak-to-peak voltage of ∼47 V current ∼1 μA, simply by finger tapping (under higher amount pressure). device generated an short-circuit 1.77 100 nA,...
Herein, a hybrid piezoelectric-cum-triboelectric energy harvesting device has been fabricated very successfully by using casein/polyvinyl alcohol (PVA)-based electrospun nanofibrous (NF) web. At first, the casein powder synthesized cow milk in laboratory. Thereafter, nanofiber prepared electrospinning method with help of PVA polymer since is not spinnable as single component due to its higher tendency form intermolecular hydrogen bonds among surrounding molecules. The used create secondary...

Femtosecond two-pulse correlation spectroscopy, temperature program desorption and density functional theory calculations are used to elucidate the mechanisms ultrafast dynamics of carbon monoxide (CO) oxidation reaction on palladium nanoparticle (Pd NP) surfaces. Two different time scales for CO Pd NPs observed: a fast channel (time constant ∼7 ps) is found when strongly bound involved, slow ∼15 weakly involved. Temperature-programmed spectroscopy confirms that channels associated with...

The process of recombinative desorption molecular oxygen (Oadsorbed + Oadsorbed = O2,gas) from the Pd(100) single crystal surface, under femtosecond laser irradiation, has been investigated with help pre- and postradiation temperature-programmed (TPD) measurements. This optical pulse-induced surface chemistry is found to depend strongly on initial temperature. threshold temperature observed be 400 K, above which this reaction remains active for absorbed fluence 2.86 mJ/cm2. Furthermore,...
