Review on medical waste management in China and Nigeria.

Medical waste management is an essential component of healthcare delivery globally due to the toxic and contagious potentials on human health and the environment. There are resource limitations in developing nations when it comes to the appropriate handling of medical wastes. In this article, we examined previous studies to evaluate the practices of medical waste management in China and Nigeria.

Research progress on elemental mercury (Hg) removal in flue gas using non-thermal plasma technology.

Elemental mercury (Hg) removal is a crucial target for mercury pollution control in flue gas. This article focuses on Hg removal in flue gas using corona discharge (CD) and dielectric barrier discharge (DBD) technologies, and provides a mechanistic perspective on the development and influencing factors of non-thermal plasma (NTP) technology for Hg removal. The influence factors include reactor configurations, power supplies, energy density, residence time, oxidation methods, gas composition, and the synergy between NTP and catalysis/adsorption, etc.

Application of a Zwitterionic Hydrophobic Associating Polymer with High Salt and Heat Tolerance in Brine-Based Fracturing Fluid.

ZIDPM, a zwitterionic hydrophobic associating polymer, has equivalent positive and negative charges and some hydrophobic monomers with twin-tailed long hydrophobic chains. It exhibits a great heat resistance and salt tolerance to the common salt in formation brine (MgCl, CaCl, NaCl, and KCl), which is attributed to its anti-polyelectrolyte effect and strong association force. High-salinity water (seawater or formation water) can be prepared as a fracturing fluid directly.
