Carbon dots (CDs), a nanomaterial synthesized from organic precursors rich in carbon content with excellent fluorescent property, are high demand for many purposes, including sensing and biosensing applications. This research focused on preparing CDs natural abundant waste, palm kernel shells (PKS) obtained oil biomass, aiming Ethylenediamine L-phenylalanine doped were produced via the hydrothe...

Lipase from Thermomyces lanuginosus (TLL) has been immobilized on a methacrylate macroporous resin coated with octadecyl groups (Purolite Lifetech®® ECR8806F). This immobilization protocol gave biocatalyst significantly higher stability than that obtained using octyl agarose. To further improve the features, we tried to covalently immobilize enzyme this support. For purpose, support was activat...

As a sensitive and selective analytical technique, gold nanoparticles-based colorimetric sensing was characterized by its simplicity and cost-effectiveness. Specific methods have been extensively developed for different targets in diverse samples. In this study, a label-free method for sensing Co in aqueous solutions was described. The target was achieved by the induced aggregation of thiosulfa...

In this work, a series of intumescent flame retarded polybutylene succinate (PBS) formulations have been developed based on ethylenediamine phosphate (EDAP) and different co-additives, i.e., zinc borate, melamine molybdate, aminated multiwall carbon nanotubes, at relatively low loading (10 wt.%). Among them, borate endows the best synergistic retardant effect with EDAP in PBS. Cone calorimetry ...

Polyols are groups of organic compounds which contain carbon and randomly linked to other atoms, especially carbon-carbon carbon-hydrogen. These mainly used as reactants make polymers. Among biopolymers, lignin is regarded the base a new polymer in polyol construction. The present study aimed investigate effects amine type (diethylenetriamine ethylenediamine) on modification lignin-based polyol...
