SO2 and NOx in flue gas are major air pollutants responsible for acid rain and photochemical smog. The removal of SO2 and NOx by activated coke is a technology with some advantages, such as simultaneous removing SO2, NOx and particulate, high efficiency of purification and no secondary pollution. The used activated cokes can be regenerated by heating or water washing treatment to recover their activity, and the concen Read More

Metal sulfides/graphene nanocomposites are of interest because of their potential applications in electrochemical and photoelectrochemical energy conversion and storage. Such materials can be prepared with in situ growth strategy, hydrothermal or solvothermal method, sol-gel method, microwave assisted irradiation method and chemical vapor deposition. This article briefly summarized recent literature and patents on t Read More

Sapphire single-crystals are one of the industrial favorite substrates for GaN film deposition and LED application as well as a model system for oxides’ aqueous interfacial chemistry studies. Contamination control of sapphire substrates is critical to the device fabrication and experimental studies of interfacial properties. Here we reviewed various methods reported in the literature including conventional and new wet-chemi Read More

The textile dyeing industry produced large volumes of wastewater every year and wastewater contains many toxic pollutants. These pollutants are difficult to deal with. Therefore, effective treatment methods and technology to dye wastewater are an important guarantee of eliminating bottlenecks in printing and dyeing industry, improving the ecological environment and safeguarding human health. In this article, the rel Read More

The cooling system is the most critical for injection mold to affecting in productivity and quality of plastic production. Traditional cooling channel is based on the conventional machining processes. It will cause long cooling time and poor cooling quality because of non-uniform cooling. This paper designed three kinds of cooling layouts for an outer housing plastic part. Simulation analysis was carried out to find the cooling effect of Read More

Research and development (R&D) in the field of biofuels in general and biodiesel in particular are not new endeavours. However, they gained momentum in the last couple of decades due to the increasing economic concerns and environmental awareness about the use of petroleum-derived fossil fuels. In this review article, recent patents and research and studies dealing with the production of biodiesel from bioresou Read More
