It is critical to develop highly effective antimicrobial agents that are not harmful to humans and do not present adverse effects on the environment. Although antimicrobial studies of graphene-based nanomaterials are still quite limited, some researchers have paid particular attention to such nanocomposites as promising candidates for the next generation of antimicrobial agents. The polyvinyl-N...

Nitro-blue tetrazolium polyvinyl butyral film dosimeters (NBT-PVB) were prepared and investigated based on radiation-induced reduction of NBT. NBT-PVB film dosimeters containing different concentrations of NBT dye from 1 to 5 mM were prepared in a solution of ethanol. The dosimeters were irradiated with g-ray from Co source at doses from 5 up to 55 kGy. UV/vis spectrophotometry was used to inve...

Despite the established use of total joint replacement for the treatment of advanced degeneration of articular cartilage, component loosening due to wear and osteolysis limits the lifespan of these joint prostheses. In the present study, nanocomposites consisting of poly(vinyl alcohol) (PVA) and bacterial cellulose (BC) nanofibers were investigated as possible improved cartilage replacement mat...

This research is aimed to undertake a comparative study on stability and thermal degradation kinetics of un-irradiated and high energy protons irradiated polyvinyl butyral (PVB) based on weight loss analysis and non-isothermal approaches. The weight loss by the un-irradiated PVB upon heating was found to be in two stages but due to high energy protons accelerated exposure following by chemical ...
