The δ-MnO2 and Cu-doped δ-MnO2 grown on Ni foams are synthesized by a simple hydrothermal method for supercapacitor electrode application. The samples are characterized by XRD, ICP-AES, SEM, and BET for its composition, structure/morphology, and BET surface area. The electrochemical properties...

Sweet sorghum (Sorghum bicolor (L.) Moench) is a promising energy crop for biofuel production. A demonstration study on cost-effective conversion of fermentable sugars in sweet sorghum stems into ethanol with advanced solid-state fermentation technology is presented in this paper. A continuous...

A new method is developed for synthesizing Ti4O7 supported Ru@Pt core–shell catalyst (Ru@Pt/Ti4O7) through pyrolysis followed by microwave irradiation. The purpose is to improve the Ru durability of PtRu from core–shell structure and strong bonding to Ti4O7 oxide. In this method, the first...

Carbon emission reduction is a long-term strategy for China to promote its economic and social development. However, emission reduction often involves a huge amount of technological investment, which could vary substantially across different provinces due to their discrepancy in economic and...
