It is of great necessity to develop new antimicrobial agents overcome the accelerated increment in drug-resistant bacteria. The main aim this work manufacture two cationic surfactants, QHETA-9 and QHETA-14, based on quaternary hexamethylenetetramine with long alkyl chains (C-9 C-14) by simple one-step alkylation reaction. These surfactants were characterized analytical statistical data, includi...

The synthesis of a 90% Ni/Al2O3 catalyst via solution combustion with various fuels was studied in this work. Catalysts high content the active component (i.e., nickel) were obtained as result Ni(NO3)2·6H2O and Al(NO3)3·9H2O mixtures fuel. fuels, such hexamethylenetetramine, glycine, urea, starch, citric acid, oxalic investigated. carried out furnace, temperature being raised from room to 450 °...

This paper presents a facile and effective method for the large-scale production of carbon dots (CDs) from diverse coconut wastes (fronds, husk shell). On comparing two different methods, namely (i) hydrothermal carbonization (ii) novel sequential synthesis processes (pyrolysis followed by sonication), latter procedure recorded higher recovery CDs (14.0%) over (2.33%). Doping agents such as ure...
