Not AvailableThe production of cellulase by Trichoderma reesei RUT C-30 under solid-state fermentation (SSF) on wheat bran and cellulose was optimized employing a two stage statistical design of experiments. Optimization of process parameters resulted in a 3.2-fold increase in CMCase production to 959.53 IU/gDS. The process was evaluated at pilot scale in tray fermenters and yielded 457 IU/gDS using the lab conditions and indicating possibility for further improvement. The cellulase could effectively hydrolyze alkali pretreated sorghum stover and addition of Aspergillus niger β-glucosidase improved the hydrolytic efficiency 174%, indicating the potential to use this blend for effective saccharification of sorghum stover biomass. The enzymatic hydrolysate of sorghum stover was fermented to ethanol with ∼80% efficiency.Not Availabl

Nickel sulfide/nitrogen-doped graphene composites: Phase-controlled synthesis and high performance anode materials for lithium ion batteries

Phase-controlled nickel sulfide (Ni3S4 and NiS 1.03) nanoparticle (NP)/nitrogen-doped graphene (NG) composites are prepared through a facile one-pot hydrothermal process. The composites show ultrahigh capacity retentions of 98.87% and 95.94% for Ni3S 4/NG and NiS1.03/NG electrodes, respectively, as anode materials for lithium ion batteries
