The filtration performance of fabrics against particles of viral size: a systematic review

Wearing a mask is part of the comprehensive strategy to suppress transmission of the SARS-CoV-2 virus and respiratory tract infections. Despite available COVID-19 vaccines, wearing a mask has remained one of the simplest and most effective ways. There was, however, little data av...

Contribution of a combined approach using refined enterotyping and non-negative matrix factorization (NMF) to the characterization of the gut microbiota in Tunisia, North Africa

Abstract This pilot study aimed to assess the enhanced capabilities of a combined approach using refined enterotyping and non-negative matrix factorization (NMF) for identifying specific microbiota patterns in healthy adults in Tunisia. Shotgun metagenomic sequencing was performe...

Realization of unconventional staircase topological Anderson phase transitions

Topological Anderson insulators provide a paradigm for disorder-induced topology, in which the underlying system turns from a trivial to a topological phase. It is widely recognized that the latter disappears at large disorder amplitude. Here, and contrary to the general belief,...

N-Acetylcysteine, Tiron, and Their Combination: In Vitro Antioxidant and Anti-Inflammatory Activities and Their Protective Effect in a Rat Model of Acetic Acid-Induced Ulcerative Colitis

Ulcerative colitis is characterized by inflammation, oxidative stress, and excessive free radical production. This study investigated the antioxidant, anti-inflammatory, and protective effects of N-acetylcysteine (NAC), Tiron, and their fixed-ratio combination in acetic acid-indu...

Effect of Different Metal Doping of ZnO Nanoparticles on Photocatalytic Degradation of Dye Wastewater

Undoped ZnO and metal-doped ZnO (ZnO:M) nanoparticles (NPs), with M [Formula: see text] Ca, V and Al, have been synthesized, with the same metal content ([Formula: see text]%), by the sol–gel method. The M-doping effects on the ZnO NPs properties are studied by a variety of techn...
