The reaction of nano-cellulose and antimony pentachloridein dichloromethane gave nano-cellulose-SbCl5. Also nano-cellulose-SbCl5 has beencharacterized by energy dispersive X-ray spectroscopy(EDX), scanning electron microscopy (SEM)and Fourier transform infrared spectroscopy(FTIR).Nano-cellulose-SbCl5has been applied as a nano-catalyst for synthesis of pyrano[2,3-d]pyrimidines from the simple on...

Pd and Co nanoparticles were deposited on cellulose for use as a heterogeneous catalyst in the bimetallic catalytic reduction reaction. The catalyst was characterized with Energy Dispersive X-Ray Spectroscopy, X-Ray Diffraction pattern, Thermal Gravimetric Analysis, Flame Atomic Absorption Spectroscopy, and Transmission Electron Microscopy, and applied in the reduction reaction of nitroarom...

Shock initiated chemical reaction experiments have been performed on a 1:l atomic ratio mixture of 20to 45,um nickel and 325 mesh crystalline silicon powders. It has been observed that no detectable or only minor surface reactions occur between the constituents until a thermal energy threshold is reached, above which the reaction goes to completion. The experiments show the energy difference be...

The positronium spin conversion reaction induced by spin-orbit interaction is investigated. We obtain the reaction rates during positronium-Xe and positronium-Kr collisions by using the Zeeman mixing of positronium states. At thermal energies corresponding to room temperature, the reaction rate for spin conversion due to spin-orbit interaction is found to be almost twice that for the positroniu...

KAl(SO4)2.12H2O is found to efficiently and heterogeneously catalyze the one-pot three-component reaction of 2-(nitromethylene)imidazolidine, malononitrile and aldehydes under mild conditions to afford the corresponding tetrahydroimidazo[1,2-a]pyridine in good yields and short reaction times. Docking  study  of  some  compounds  in  the  active  site  of  α-glucosidase demonstrated  that  these...

Electron transfer reaction in a polar solvent is modeled by a solute dipole surrounded by dipolar molecules with simple rotational dynamics posted on the three-dimensional distorted lattice sites. The interaction energy between the solute and solvent dipoles as a reaction coordinate is adopted and free energy landscapes are calculated by generating all possible states for a 26 dipolar system an...
