Ammonium perrhenate is widely used in alloy manufacturing, powder processing, the catalytic industry, and other fields.Recrystallization can improve the specific surface area of ammonium perrhenate, reduce its particle size, and improve its particle size distribution uniformity.Therefore, recrystallized ammonium perrhenate can obtain better applica
Icebergs are one of the important components of Antarctic ice loss, and their markbroyard.com spatial distribution and volume changes have a profound impact on ocean circulation, sea ice formation, freshwater balance and carbon cycle in the Southern Ocean, and ship navigation.Therefore, effective monitoring of icebergs is of great significance.Iceb
Background: COVID-19 is a novel coronavirus infectious disease associated with the severe acute respiratory syndrome.More and more patients are being cured due to the development of clinical guidelines for COVID-19 pneumonia diagnosis, treatment, and vaccines.However, the long-term impact of COVID-19 on patients after recovery is unclear.Currently
Abstract Lipid II precursor and its processing by a flippase and peptidoglycan polymerases are considered key hot spot targets for antibiotics.We have developed a fluorescent anisotropy (FA) assay using a unique and versatile probe (fluorescent lipid II) and monitored direct binding between lipid II and interacting proteins (PBP1b, FtsW and MurJ),
