Byproducts derived from the food industry are an interesting biomass to valorize as they cheap source, their generation does not compete with and feed production, utilization solves waste disposal issue. In this work, we focused on production of a series polyesters using cardanol-derived diol produced inedible shell cashew nuts. The synthesized polymers 100% biobased since diacid components str...

Hydrophobically modified chitooligosaccharides (COSs) were tested for suitability as an emulsifier in cationic bituminous emulsions. COSs with polymerization degrees (DPs) of 5, 10, 15, and 20 obtained by nitrous acid deamination. A complete study on depolymerization precise product side characterization was undergone. Chemical modification performed to achieve amphiphilic structures using thre...

BACKGROUND Propolis is a sticky, dark brown resinous residue made by bees that is derived from plant resins. It is used to construct and repair the nest, and in addition possesses several diverse bioactivities. Here, propolis from Apis mellifera from Nan province, Thailand, was tested for antibacterial activity against Gram(+ve) (Staphylococcus aureus and Paenibacillus larvae) and Gram(-ve) (Es...
