Amide compounds which are closely related to people's clothing, food, shelter, and transportation play an important role in daily production life. Therefore, exploring improving the synthesis of amide is one topics that researchers have focused on recent years. The hydration nitriles amides environmental-friendly 100% atom economic method. Among reported nitrile catalytic systems, metal complex...
The synthesis of gallium nitride nanowires (GaN NWs) by plasma enhanced chemical vapor deposition (PECVD) are successfully demonstrated in this work. The simple and green synthesis route is to introduce gallium oxide (Ga2O3) and nitrogen (N2) for the growth of nanowires. The prepared GaN nanowires have a single crystalline wurtzite structure, which the length of some nanowires is up to 20 μm, w...
Current work proposes an inimitable composite, with great electrical conductivity and quite enhanced surface area, (including conducting polymers (poly (cathechol)), Cu2O–carbon dots and green synthesized gold nanoparticles) for detecting acute carcinoembryonic antigen. At current work, the electropolymerization was offered instead of enzyme-catalyzed polymerization of poly (catechol). <b...
We have introduced a selective synthesis of tertiary amines using alkyl halide and ammonium salts as the amine sources in water. This green process has outstanding superiorities, such as being eco-friendly, possessing ammonium salts, and using water as a green solvent in the absence of organic ligands or catalysts. It is worth mentioning that the presence of t-Butyl alcohol and potassi...
Grape seed is a waste product from the wine and juice industries. However, vegetable oil can be extracted it, which renewable chemical with huge potential application after modifications, such as epoxidation maleinization processes. This paper therefore deals use of grape oil, to produce its epoxidized maleinized derivatives. Both derivatives were synthesized in order improve conversion (99.4%)...
Zeolite X is a potential electromagnetic wave (EMW) absorption material owning to its advantages of good dielectric properties, light weight and large specific surface area. Herein, high-purity zeolite was prepared from fly ash using green synthesis approach, in which only trace water used achieved zero discharge waste water. Physiochemical properties fabricated were comprehensively evaluated t...
