In this work, we use a well-defined water-soluble macrocyclic molecule cucurbit[5]uril (CB5) to modify 2D TiCT MXene and assemble a novel high-performance adsorbent CB5-TiCT for Sr ion by density functional theory and experimental methods. The structural stabilities of two distinct types of CB5-TiCT (T = F, O and OH) complexes, i.e.

Objective: Selective decontamination of the digestive tract (SDD) has been investigated as a strategy to reduce the incidence of ventilator-associated pneumonia (VAP) and other healthcare-associated infections in intensive care unit (ICU) patients receiving mechanical ventilation. There is some evidence to suggest that the use of SDD is associated with a reduction in healthcare-associated infection and mortality; however, the uptake of SDD in ICUs in Australia and New Zealand (ANZ) remains low. To better understand the potential reasons, we designed a questionnaire to gather views from specialists in intensive care medicine, infectious diseases, and medical microbiology.

This review addresses the effects of various decontamination methods on the wettability of titanium and zirconia dental implants. Despite extensive research on surface wettability, there is still a significant gap in understanding how different decontamination techniques impact the inherent wettability of these surfaces. Although the literature presents inconsistent findings on the efficacy of decontamination methods such as lasers, air-polishing, UV light, and chemical treatments, the reviewed studies suggest that decontamination alters in vitro hydrophilicity.

Single-atom catalysts (SACs) have been increasingly acknowledged for their performance in sustainable Fenton-like catalysis. However, SACs face a trade-off between activity and stability in peroxymonosulfate (PMS)-based systems. Herein, we design a nano-island encapsulated single cobalt atom (Co-ZnO) catalyst to enhance the activity and stability of PMS activation for contaminant degradation via an "island-sea" synergistic effect.

Facemask materials have been under constant development to optimize filtration performance, wear comfort, and general resilience to chemical and mechanical stress. While single-use polypropylene meltblown membranes are the established go-to material for high-performing mask filters, they are neither sustainable nor particularly resistant to sterilization methods. Herein an in-depth analysis is provided of the sterilization efficiency, filtration efficiency, and breathing resistance of selected aerosol filters commonly implemented in facemasks, with a particular focus on the benefits of nanofibrous filters.
