Isfahan University of Tech team reports new efficient pretreatment method for rice straw to boost yield of cellulosic ethanol

Green Car Congress

Researchers at Isfahan University of Technology (Iran) report the efficient production of cellulosic ethanol from rice straw using a new sodium carbonate pretreatment method. Rice straw was treated with sodium carbonate (Na 2 CO 3 )prior to enzymatic hydrolysis and fermentation. and 1 M sodium carbonate solution.

Antimony/carbon nanocomposite anode for Na-ion battery shows high capacity and stability

Green Car Congress

Researchers at Wuhan University (China) have synthesized a Sb/C (antimony/carbon) nanocomposite for use as an anode material in a room-temperature sodium-ion (Na-ion) battery. A sodium disk served as the counter and reference electrode. Source: Yang et al. Click to enlarge. doi: 10.1039/C2CC32730A.
