Bis(2-hydroxyethyl) terephthalate (BHET) obtained from waste poly(ethylene terephthalate) bottles was used to synthesize polyurethane foams (B-PUF) and the fireproof B-PUF in the presence of nonhalogen flame retardant, namely, aluminum hydrogen phosphonate (AHP). Loading of 25 php AHP was needed for B-PUF/AHP to achieve UL-94 V-0 rating. The thermal stability of B-PUF was improved with the additio...... hiện toàn bộ

CuFe2O4/cellulose nanocrystal (CuFe2O4/CNC) composite featured high magnetic activity was prepared by a facile and one-pot solvothermal method. Based on the solvothermal condition, nanometer-sized magnetic CuFe2O4 ferrite particles (CuFe2O4 NPs) were directly synthesized and CNC was coated on the surfaces of CuFe2O4 NPs. The composition, structure, morphology, and magnetic property of prepared CuF...... hiện toàn bộ
Isolation and screening of Pseudomonas isolates enhance salinity tolerance of peanut (Arachis hypogaea L.)

The application of plant growth-promoting rhizobacteria (PGPR) is one of the most promising alternative approaches to improve plant growth under salt stress. Among PGPR, Pseudomonas is a bacterial genus that possesses a variety of mechanisms for plant-growth-promoting and induction of biotic as well as abiotic stress tolerance. In this study, we screened three potential strains and tested the grow...... hiện toàn bộ
