Preparation of Bio-Nanocomposite membrane for methylene blue adsorption
We successfully developed the bionanocomposite membrane from the Vietnamese-rich materials by dry/wet method. The MB adsorption of the bionanocomposite CS/MMT membrane has been improved about 1.2 – 1.3 times higher than the CS, CS/MMT bulk film. The results indicated the advantages of CS/MMT membranes over conventional nanocomposite film. Furth...

Định týp (genotyping) virus viêm gan vịt type 3 phân lập tại Việt Nam từ 2009-2013 - Đỗ Thị Roan
SUMMARY The entire sequences for VP1 gene of ten DHAV samples isolated during 2009-2013 from six provinces in Vietnam were obtained. Based on high identity (91-100%) for nulcleotide and amino acid, DHAV strains of Vietnam belonged to genotype 3 (DHAV-3) and have a “hyper variable region” at C-terminal of VP1. Notably, 6/10 strains of Vietnam sho...
