During a recent visit to Shenzhen, Guangdong province, filmmaker JT Singh noticed how the sound of packing tape can be heard at all times throughout Huaqiangbei, the massive electronics hub located at the heart of the city.In this digital age where Chinese are furiously shopping online, workers at places like Huaqiangbei pack hundreds of boxes of customer orders every day, and in the process expend massive amounts of packing tape.This incident has since spurred Singh to produce a short film to explore how this practice affects the environment. wristband designsilicone bracelets custom cheapwristbands onlineprintable wristbandssilicone fidget spinner
SHENYANG -- Chinese scientists have developed an artificial sponge material that can separate oil and water to be used for treating water contaminated by industrial sewage.A paper on the research undertaken by the Institute of Metal Research under the Chinese Academy of Sciences was published on the latest issue of the international journal Advanced Materials Interfaces.The porous material made with nano-crystalline cellulose and graphene composite has a high absorption capacity. It is 97 percent effective in water and oil separation, according to Liu Dongyan, a researcher with the institute based in Shenyang, capital of North China's Liaoning Province.Liu said that industrial sewage contains various oils and organic components that are ecologically hazardous once mixed with water. The new material provides a low-cost industrial sewage treatment solution.She explained that the base material of the polyurethane sponge is cost-effective. Only the small amount of graphene in the coating is still expensive. However, with the increasing production of graphene in China, the price would gradually come down.
