The efficiency of peracetic acid on drinking-water conservation and sterilization was investigated. It was determined in watering experiments that a starting concentration of 0.01-0.02% peracetic acid was required in order to guarantee the sterility of water and water-bottle for a duration of one week. As the applied peracetic acid concentration could be reduced by addition of organic substances such as saliva and stomach content, the possibility of peracetic acid resorption by the animal is negligible.

OH-mediated advanced oxidation processes (AOPs) are widely used in wastewater treatment and drinking water purification. Recently, an increasing number of studies have indicated that common inorganic nitrogen ions can efficiently generate •OH under UV irradiation, demonstrating strong performance in the degradation of various contaminants. Conversely, the presence of inorganic nitrogen ions in UV or other oxidation processes dramatically increases the yield of toxic nitro (so)-aromatic products and the formation potential of nitrogenous disinfection by-products with high genotoxicity and cytotoxicity.

Recently, transparent wood (TW) has been considered for many energy-efficient building products, such as windows and decorations. However, the existing TW still faces issues with size and thickness, as well as problems with functional fillers affecting the optical and mechanical properties of TW, which limits its wide application in the window products. In this study, a wood composite material (WCM) with good optical, mechanical, and thermal insulation and UV-shielding properties was prepared by using delignified wood (DW), methyl methacrylate (MMA), and 4-vinylphenylboric acid (VPBA).

Peracetic acid (PAA) is an emerging disinfectant known to be highly effective against various microorganisms. However, the capability of PAA to eliminate spores under different conditions and its application in liquid and gaseous forms remain unclear. Here, we aimed to develop a stabilized single-composite PAA and evaluate its disinfection efficacy in both liquid and gaseous form against suspended or surface-coated spores under varying temperature and humidity conditions.

Background: The use of laryngeal masks (LM) has increased widely today, both in anesthesia and in emergency cases. LM are available as reusable and disposable. Although reuse of disposable LM is not recommended, they are reused again after decontamination with different methods in anesthesia units in some countries.

Klebsiella pneumoniae is an opportunistic pathogen responsible for various infections in humans and animals. It is known for its resistance to multiple antibiotics, particularly through the production of Extended-Spectrum Beta-Lactamases (ESBLs), and its ability to form biofilms that further complicate treatment. This study aimed to isolate and identify K.
