Summary: The study investigated an oxidative process using hydrogen peroxide to dissolve metallic antimony, strip dissolved antimony ions, and ensure compatibility with structural materials in nuclear reactor coolant systems. This process can effectively remove antimony activity and reduce radiation exposure to workers. The presence of hydrogen peroxide increased the rate of dissolution of metallic antimony. Three substrates, including strong base anion exchange resin and two chitosan-TiO2 based substrates, were equally efficient in removing dissolved antimony. The process could dissolve antimony without significant re-deposition on the oxide coated carbon steel surface and dissolve antimony incorporated in the oxide film of zircaloy. Corrosion compatibility tests showed that only Monel-400 underwent pitting attack at pH 10.2.

Summary: Covid-19 has sparked interest in decontamination techniques, particularly using UV-C light. This study used a large decontamination chamber to irradiate surfaces with UV-C light and successfully inactivated SARS-CoV-2 within seconds. The study also estimated the sensitivity of SARS-CoV-2 to UV-C light in their experimental conditions. The results show the potential of using UV-C for rapid and effective decontamination.

Summary: Safeguarding the seafood industry is crucial to protect human health. However, eliminating enteric viruses, especially in live shellfish, is challenging. Current disinfection methods are effective against bacteria but have limited effectiveness against enteric viruses. Therefore, alternative non-thermal technologies and novel diagnostic approaches are needed to ensure the safety of shellfish. Risk management planning and real-time ecosystem monitoring are also important for mitigating potential contaminant threats.

Summary: Due to the similar reactivity of organic hydroperoxides (OHPs), HPLC separation is typically required for their indirect quantification in mixtures. NMR is an ideal tool for simultaneous quantification of OHPs in mixtures due to its high sensitivity to chemical shifts, but the concentration of these analytes in the samples of interest is usually below the sensitivity of standard NMR experiments.

Summary: Researchers have developed an artificial compartment system based on lipidoids that can control enzyme activity using light. This system utilizes the reversible photoisomerization of azobenzene lipidoids to regulate the permeability of the compartment membrane and control enzyme activity. Unlike traditional inhibitors or noninhibitor systems, this approach does not require mutation or modification of enzymes, resulting in minimal loss of enzyme activity. Furthermore, this method provides a generic strategy for controlling multiple enzymes and has the potential to be applied in biological mechanism research and precision medicine.

Summary: Ultraviolet germicidal irradiation, moist heat, and microwave-generated steam processing are effective methods for decontamination of filtering facepiece respirators, while vaporized hydrogen peroxide is a suitable alternative with longer decontamination durations and higher costs. Ethylene oxide, although effective, may leave toxic residues and is more difficult to implement.

Summary: This review examines the literature on vaporized hydrogen peroxide (vHP), hydrogen peroxide gas plasma (HPGP), and aerosolized hydrogen peroxide (aHP) as methods for decontamination of filtering facepiece respirators (FFRs). The study found that vHP has the most evidence supporting its use in FFR decontamination, consistent with CDC recommendations.

Summary: The objective of this study was to evaluate the effectiveness of a decontamination protocol, two disinfectants, and a sealant in preventing internal bacterial colonization of implants. The results showed that the use of disinfectant agents or a sealant did not provide any additional benefit compared to the decontamination protocol alone.
