Zinc Oxide Nanoparticles (ZnO-NPs) and Silver Nanoparticles (Ag-NPs) are advanced nanomaterials that have shown tremendous benefits in addressing environmental and health challenges, including the eradication of carbon monoxide (CO) emissions and airborne bacteria/viruses that affect the respiratory and immune systems. Here’s how they work: 1. Combating CO Emissions CO is a harmful gas produced by…

Oxidation in Zinc Oxide Nanoparticles (ZnO-NPs) is a powerful mechanism for eliminating air pollution, particularly through photocatalytic oxidation. This process leverages the unique properties of ZnO-NPs to break down harmful pollutants into less toxic or non-toxic substances. Here’s a detailed explanation of how oxidation in ZnO-NPs helps eliminate air pollution: 1. Photocatalytic Oxidation Mechanism ZnO-NPs are semiconductor materials…

In our modern, fast-paced lives, we spend a significant portion of our day indoors, whether at work or in the comfort of our homes. However, the quality of the air we breathe within these enclosed spaces can have a profound impact on our health and well-being. Sick Building Syndrome (SBS) is a phenomenon that many…

Within the confines of our homes, a multitude of invisible threats silently jeopardize our overall health and well-being. Airborne bacteria, viruses, air pollution, mold, and noxious odors are covertly present in various corners, posing potential risks to our quality of life. The below video delves into these indoor contaminants, highlighting the precise locations they lurk…

The SARS-CoV-2 virus endures for days on plastic or metal but disintegrates soon after landing on copper surfaces. Here’s why When researchers reported that the novel coronavirus causing the COVID-19 pandemic survives for days on glass and stainless steel but dies within hours after landing on copper, the only thing that surprised Bill Keevil was…

They are all around us, some strong, some weak, some easy to destroy some resilient in their surroundings and some even spread through coughs and sneezes. Tiny infectious microbes, from the virus that causes COVID-19 to airborne bacteria, kill millions of people around the world each year. Now engineers from ETH Zurich have studied how…

In 1832, 1849, and 1852, 200 employees from a copper smelter in Paris were unaffected by the cholera outbreaks, and this caught the attention of physician Victor Burq. 500 employees, who worked in the same area, were also spared from the cholera outbreak. This made Burq conclude that copper had given these people some kind…

A simple technique to make a common killing virus material significantly more effective is a breakthrough from the Rice University labs of Andrew Barron and Qilin Li who have taken nano particles that everyone’s been using for years and improved its performance without any real cost, said Barron, Rice’s Charles W. Duncan Jr.-Welch Professor of…
