AI Article Synopsis

  • Scientists have created new biocidal agents that can explode and kill bacteria, using special compounds called iodine-rich molecular perovskites.
  • These compounds contain a lot of iodine and are super powerful when they detonate, reaching speeds of over 6 kilometers per second.
  • One of the compounds, called DAI-4, is especially effective against bacteria and has advantages like being cheap and easy to make in large amounts.

Article Abstract

Unlabelled: Epidemics caused by pathogens in recent years have created an urgent need for energetic biocidal agents with the capacity of detonation and releasing bactericides. Herein we present a new type of energetic biocidal agents based on a series of iodine-rich molecular perovskites, (Hdabco)M(IO) (dabco = 1,4-diazabicyclo[2.2.2]octane, M = Na/K/Rb/NH for DAI-1/2/3/4) and (Hdabco)Na(HIO) (DAI-X1). These compounds possess a cubic perovskite structure, and notably have not only high iodine contents (49-54 wt%), but also high performance in detonation velocity (6.331-6.558 km s) and detonation pressure (30.69-30.88 GPa). In particular, DAI-4 has a very high iodine content of 54.0 wt% and simultaneously an exceptional detonation velocity up to 6.558 km s. As disclosed by laser scanning confocal microscopy observation and a standard micro-broth dilution method, the detonation products of DAI-4 exhibit a broad-spectrum bactericidal effect against bacteria (, and ). The advantages of easy scale-up synthesis, low cost, high detonation performance, and high iodine contents enable these periodate-based molecular perovskites to be highly promising candidates for energetic biocidal agents.

Article Synopsis
  • Formaldehyde (HCHO) is a harmful substance found in various products, and the study introduces a new sensitive sensor using Pd nanoclusters integrated into a mesoporous TiO structure to detect it.
  • The sensor benefits from a large surface area and enhanced adsorption capacity, resulting in quick response/recovery times and excellent sensitivity, detecting HCHO at very low concentrations (4.51 ppb) under UV light.
  • The design includes a wearable gas sensing band for real-time HCHO detection in cigarette smoke, showing potential for environmental monitoring and smart sensing applications.

Wearing face masks is the best way to stop the spread of respiratory infections. However, if masks are not sterilized, changing them too frequently can actually increase the risk of cross-contamination. Herein, the construction of an antipathogen photocatalytic mask with carbon vacancy-modified carbon nitride nanosheets (g-CN-V Ns) coated on the non-woven fabrics of the out layer of the mask, offering effective and long-term protection against damaging pathogens when exposed to light is reported.
