A novel conductometric hydrogen sulfide (H2S) sensor was fabricated by AC dielectrophoretic assembly of amino acid mediated grown gold nanoparticles across microfabricated gold electrodes. Excellent sensing performance toward hydrogen sulfide, including a sensitivity of 29.84% ppm , a lower detection limit in the sub-ppm level, the upper detection limit of 2 ppm, and a response time of<20 s for...

INTRODUCTION Saccharomyces cerevisiae is the micro-organism of choice for the conversion of fermentable sugars released by the pre-treatment of lignocellulosic material into bioethanol. Pre-treatment of lignocellulosic material releases acetic acid and previous work identified a cytochrome oxidase chaperone gene (COX20) which was significantly up-regulated in yeast cells in the presence of acet...

A pot experiment was conducted in a completely randomized design with five treatment and five replication, in each replication were 6 plants used. The study of zinc sulphate (ZnSO4) application (20 and 40 ppm) and Salicylic acid (SA) application (50 and 150 ppm) was compared to the control (distillated water) on growth and flowering Petunia hybrid. For each plant was used 10...
