Tetracycline (TC) is one of the most common broad-spectrum antibiotics. However, typically less than 30% of the antibiotic dose was absorbed by human and animal, while the remainder released into the environment through urine. The coexistence of TC and water hardness ions (Ca2+ and Mg2+) in natural water is a widespread pollution phenomenon. Especially, TC and water hardness ions could easily form TC-metal complex pollution in the environment.
China has developed the Chinese Aeronautic Remote Sensing System (CARSS) to conduct detailed observations and monitoring of Earth's surface that was marked by its successful passing of final acceptance on July 29 in Yingkou, Liaoning Province.
Cell membrane has attracted extensive attention in worldwide and exhibited great application potential for drug delivery systems (DDSs). However, along with the wide application of the cell membrane in DDSs, some limitations seriously limit cell membrane-based DDSs in clinical use, such as the complexity of preparation technology. Therefore, it is highly important to develop methods for the preparation of biomimetic cell membranes in a simple and high-yield manner.
Non-molecular carbon disulfide (CS2) is widely viewed as a Bridgman’s polymer, [-(C=S)-S-]n which found by Bridgman in 1941, utilizing high pressure techniques. In Bridgman’s polymer, there are only carbon-sulfur bonds without bonds about carbon atoms, and all carbon atoms are 3 fold coordinated, which is a little different from the carbon in carbon dioxide (CO2).
It’s July again. EAST superconducting tokamak in ASSIP, HFIPS started its annually joint experiments together with worldwide participants from PPPL, MIT, DIII-D, ITER, GA, NIFS, etc.
