In this study, to detect thiram electrochemically, a simple nanosensor based on glassy carbon electrode (GCE) modified with green-synthesized Ag and Au nanoparticles was designed. AuNPs@AgNPs/GCE gave considerably greater signal for 5 ppm in pH 3.0 phosphate buffer solution using adsorptive stripping differential pulse voltammetry compared bare GCE. Under ideal conditions, the produced linear concentration calibration curve extending from 0.2 1.4 thiram, limits of detection quantification...

We present ab initio study using dispersion-corrected density functional theory calculations to investigate the hydrogen interaction with Ti-coated, one end closed, single-walled carbon nanotube (SWCNT). Our results demonstrate that a single Ti atom binds up five molecules on SWCNT cap top, whereas adsorption of four is energetically more favourable. The analyses from energy profile, highest occupied molecular orbital–lowest unoccupied orbital gap and Mulliken charge distribution show...
