AI Article Synopsis

  • The text discusses the importance of reducing virus spread as a primary strategy against outbreaks like the COVID-19 pandemic, emphasizing the need for sustainable methods.
  • It introduces a biodegradable antiviral filtration membrane made from food-grade milk proteins and iron oxyhydroxide nanoparticles, which are both non-toxic and environmentally friendly.
  • The membrane effectively targets various viruses, including SARS-CoV-2 and H1N1, suggesting its potential to be a valuable tool in managing current and future viral health crises.

Article Abstract

Minimizing the spread of viruses in the environment is the first defence line when fighting outbreaks and pandemics, but the current COVID-19 pandemic demonstrates how difficult this is on a global scale, particularly in a sustainable and environmentally friendly way. Here we introduce and develop a sustainable and biodegradable antiviral filtration membrane composed of amyloid nanofibrils made from food-grade milk proteins and iron oxyhydroxide nanoparticles synthesized in situ from iron salts by simple pH tuning. Thus, all the membrane components are made of environmentally friendly, non-toxic and widely available materials. The membrane has outstanding efficacy against a broad range of viruses, which include enveloped, non-enveloped, airborne and waterborne viruses, such as SARS-CoV-2, H1N1 (the influenza A virus strain responsible for the swine flu pandemic in 2009) and enterovirus 71 (a non-enveloped virus resistant to harsh conditions, such as highly acidic pH), which highlights a possible role in fighting the current and future viral outbreaks and pandemics.

The natural minerals with semiconducting properties possess photochemical activity through generating reactive oxygen species (ROSs) and affect the fate of adsorbed organic pollutants. Iron oxyhydroxides occur in different polymorphic structures under various geological and climatic conditions in natural environment. However, the difference in their photoactivity has not been well understood.

Electrochemical and shake flask tests were used to examine the corrosion characteristics of typical gangue minerals in biometallurgical systems and their impact on microbial communities. The results show that the solubility order of the three gangue minerals is feldspar, mica, and quartz in descending order. Their corrosion processes are mainly controlled by cathodic electron-donating processes.

Bismuth oxide (BiVO) is considered one of the most promising semiconductors for photoelectrochemical (PEC) water splitting due to its highly theoretical photocurrent of 7.5 mA cm. However, its sluggish kinetics and severe photocorrosion still hinder the real application of a large-area BiVO photoanode.

Article Synopsis
  • Arsenic-contaminated groundwater, particularly As(III), poses a global environmental challenge due to its toxicity and difficulty in removal; this study focuses on developing a chloramine-functionalized iron hydroxide cellulose nanofibrous membrane (Fe-CNFM-Cl) to address this issue.* -
  • The Fe-CNFM-Cl membrane not only adsorbs As(III) but also oxidizes it to a more removable form, As(V), allowing significant reduction of arsenic levels from 1418.73 μg L to below drinking water standards in about 300 minutes.* -
  • This innovative membrane shows a high capacity for arsenic removal across a wide pH range, can recover its functionality after use

Earth-abundant transition metal phosphide (TMP) nanomaterials have gained significant attention as potential replacements for Pt-based electrocatalysts in green energy applications, such as the hydrogen evolution reaction (HER), oxygen evolution reaction (OER), and overall water splitting. In particular, FeP nanostructures exhibit superior electrical conductivity and high stability. Moreover, their diverse composition and unique crystal structures position FeP nanomaterials as emerging candidates for HER electrocatalysts.
