Summary: Corrosion of metallic materials is a long-standing problem in engineering fields. Metal organic frameworks (MOFs)-based surfaces and coatings have great potential in developing efficient and durable anticorrosion materials. The tailorable porous structure and numerous active sites of MOFs make them ideal for developing various protective functionalities. MOFs-based anticorrosion surfaces and coatings can be divided into two categories: composite surfaces/coatings using MOFs as nanofillers and surfaces/coatings using MOFs as functional substrates.

Summary: Due to their good safety, low cost, environmentally friendliness, and relatively high energy density, aqueous zinc-ion batteries (ZIBs) are considered as promising alternatives to lithium-ion batteries. However, the zinc metal anode in aqueous ZIBs is prone to dendrite growth and side reactions. In this study, an ultrathin carbon coating is applied on the zinc metal anode to suppress dendrite growth and alleviate side reactions. The modified zinc electrode shows a long cycling life and improved rate performance and cycling stability compared to bare zinc electrode.

Summary: Metal-polyphenol networks (MPNs) are versatile coatings used for regulating membrane surface chemistry and forming thin separation layers. The coordination between plant polyphenols and transition metal ions enables a green synthesis method for thin films, which enhance membrane hydrophilicity and fouling resistance. MPNs have been utilized to fabricate customizable coating layers for high-performance membranes in various applications. This review presents the recent progress of MPNs in membrane materials and processes, with a focus on the important role of tannic acid-metal ion (TA-Mn+) coordination in thin film formation.

Summary: Sepsis is a dysregulated host immune response to microbial invasion or tissue damage, resulting in organ injury at a site distant from the infection or damage. This method describes a protocol for studying host responses during Salmonella Typhimurium infection-induced septic peritonitis in mice. The model involves culture preparation, intraperitoneal injection to induce septic peritonitis, and methods for studying systemic host responses. This model can be useful for studying immune responses during bacterial sepsis, the role of genes in disease progression, and the effects of drugs to attenuate sepsis.

Summary: The perfluorodecanethiol (PFDT) coating has demonstrated superior performance in terms of heat transfer and durability compared to other organic coatings such as perfluorodecyltriethoxysilane (PFDTS) and perfluorodecyl acrylate (PFDA). Despite being a monolayer, the PFDT coating exhibited dropwise condensation for at least 63 hours without deterioration, showcasing its hydrolytic stability. Additionally, the cost of thiol functionalization per area was the lowest among the surface hydrophobic treatments used in the study.

Summary: Salmonella Typhimurium infection in mice causes significant loss of immature double negative and double positive thymic subsets, while mature single positive subsets are more resistant. The study investigated the impact of a wild type virulent strain and a virulence-attenuated strain on the thymocyte sub-populations in different mouse strains. The results showed that the virulent strain caused acute thymic atrophy, with greater loss of thymocytes in autoimmune-prone mice. The attenuated strain caused progressive thymic atrophy in all mouse strains, with extensive loss of immature thymocytes. The susceptibility of thymocyte sub-populations varied depending on bacterial virulence and host background.
