A heterogenous catalyst in the form of Au nanoparticles (Au NPs) immobilized porous manganese oxide (Mn5O8) microspheres was synthesized. The sol-gel templating method used for synthesis Mn5O8 microspheres. showed good performance when compared with similar catalysts oxidation benzyl alcohol. (Au@Mn5O8) obtained by immobilization NPs on performed 99.4% alcohol conversion and 100 % benzaldehyde ...

One way to produce seeds in a short time is through vegetative propagation by vitro culture. This study aims determine the effect of application certain concentration Benzyl Amino Purine (BAP) on multiplication taro shoots (Colocasia esculenta L.). The research was carried out at Laboratory Food and Agriculture Security Service Bogor City, August 2020 – February 2021. test with one factor compl...

in recent years, zinc oxid nanotubes have attracted much attention. the direct use of , zinc oxidnanotubes modified by sio2 as recoverable catalysts for organic reactions is very rare. the catalystswere characterized by xrd. the average particle size of zno catalysts is 57 nm and there are highdensitydefects on nanotubes surfaces . a simple and efficient method for the imidazol derivativessynth...

al-mcm-41 nanoreactors is found to be a remarkable efficient catalyst for one-pot multicomponent cyclocondensation of benzil, aniline or ammonium acetate and aromatic aldehydes for the synthesis of polysubstituted imidazoles under solvent-free conditions. the reaction was efficiently promoted by 10 mg nano-al-mcm-41 and the heterogeneous catalyst was recycled for four runs in this reaction with...

Developing a protocol for somatic embryogenesis (SE) adult mother plants of Jatropha curcas, aids to overcome problems such as harvesting time and an uneven yield, providing the opportunity propagate proven elite genotypes. Until now, several authors have achieved SE in J. curcas using different explants, however, none these protocols been used plant material. Furthermore, challenge overcoming ...

A new series of complexes the 2-((1E,2E)-1,2-diphenyl-2-(thiazol-2-ylimino)ethylidene)amino)phenol (DPTYEAP) has been synthesized by reaction ligand with metal chlorides Ni(II), Cu(II), Pt(IV), and AgNO3 in ethanol as a solvent. The was prepared for two steps. In first step, compound (A) reacting 2-aminothiazol benzil ethanol. Another step is preparation from 2-aminophenol. structures its were ...
