This study is concerned with finding an improved route to achieve superior properties of carbon nanotube (CNT)-reinforced nanocomposites by designing their interface using multi-scale modeling. CNTs, widely used as fillers in nanocomposites, and polymer epoxy matrices, are coarse-grained and simulated via dissipative particle dynamics. Then, reverse-mapping of the coarse-grained models into ato...

A simple one-step technology of wire electrospinning is presented for the manufacturing air-permeable CO2-capturing membranes, easily transferable to industrial production lines. The design chemically-modified polyurethane nanofiber membranes CO2 capture was based on a combination molecular modeling and technological experiments using (i.e., modifying agent dissolved directly in spinning soluti...

Given the ever-growing environmental concerns, repurposing natural materials is a viable approach to developing novel green materials. Thus, use of fish scales as reinforcement in composites has great potential. This work aimed evaluate influence using arapaima DGEBA/TETA epoxy on mechanical and thermal properties. Composite plates 30 vol% were analyzed through compression tests, DMA, TGA, DSC....

A suitable method to functionalize the surface of polyethylene terephthalate (PET) consists in the chemical treatment with different amines such as triethylenetetramine (TETA), or tetraethylenepentamine (TEPA). The paper describes the influence of PET surface amination on the mechanical and water-sorption properties. Superficial chemical treatment involves micro-structural changes such as molec...

Fifty-five Aeromonas hydrophila isolates, which were colected from infected tilapia Oreochromis niloticus at aquaculture farms in Thailand, were tested for their antimicrobial susceptibilities against 11 drugs including ampicilin (ABPC), kanamycin (KM), streptomycin (SM), chloramphenicol (CP), florfenicol (FF), tetracycline (TC), sulfamonomethoxine (SMMX), trimethoprim (TMP) and three quinolone...

Conserved motif C, identified within members of the major facilitator superfamily (MFS) of transport proteins that mediate drug export, was examined in the tetracycline resistance efflux protein TetA(K) from Staphylococcus aureus; motif C is contained within transmembrane segment 5. Using site-directed mutagenesis, the importance of the conserved glycine (G151, G155, G159, and G160) and proline...

The genome of a multidrug-resistant Salmonella Agona isolated from Larus audouinii (Audouin's gull) in Spain was examined. The isolate showed high levels of resistance to different antimicrobials, including third generation cephalosporins and fluoroquinolones, which is a public health concern as those being used to treat severe salmonellosis in humans. Whole genome sequencing revealed the strai...
