A review of bismuth-based sorptive materials for the removal of major contaminants from drinking water.
Abstract In recent years, bismuth has gained attention of many researchers because of its sorptive properties. Sorptive properties of bismuth compounds are used for removal of ionic contaminants from aqueous solution. In this paper, an attempt is made to review the recent developments in the area of contaminant removal from aqueous solutions using bismuth-based media. […]

More stringent IPCC guidelines include accounting for CF4 by-product formation and emissions.
BURGESS HILL, England-The Intergovernmental Panel on Climate Change (IPCC), the United Nations’ body for assessing the science related to climate change, has just released the latest refinement to its 2006 Guidelines. As part of an effort to tackle climate change, the refined regulations tighten control on new greenhouse gases used in semiconductor manufacturing and increase […]

Indigenous microbes induced fluoride release from aquifer sediments.
Abstract Release of fluoride from Quaternary sediments produces F-contaminated groundwater which threatens the health of millions of people worldwide. Despite the mechanisms of fluoride release from sediments are documented by numerous studies, it remains poorly understood that whether indigenous microbes participate in or not for the formation of F-rich groundwater by releasing fluoride from aquifer […]

Composite material that can absorb electromagnetic radiation developed
The rising level of electromagnetic radiation emitted by communication devices and electronic instruments is becoming a cause of concern. An effective shielding material having suitable electrical and magnetic properties can help reduce the problem of Electromagnetic Interference (EMI) as it can reflect or absorb the energy of such radiation. However, absorption type shields are environmentally […]

Fluoride treatment protects solar cells
Fluoride treatments aren’t just for protecting your teeth. According to a new study, an ingredient found in toothpaste can also help prevent solar-cell decay (Nat. Energy 2019, DOI: 10.1038/s41560-019-0382-6). The finding may lead to simple chemical procedures for extending the lifetime of low-cost photovoltaic (PV) devices based on a promising class of materials called perovskites. […]

Big toenail and hair samples as biomarkers for fluoride exposure – A pilot study.
Because biomarkers (ie, biological markers) can help in the detection and prevention of clinical disease by recognizing changes in biological samples, researchers intended to determine whether there is an association between fluoride concentrations in big toenail (hallux) clippings, hair and the level of fluoride in the water of an endemic and non-endemic fluorosis region. In […]

A critical review on geochemical and geological aspects of fluoride belts, fluorosis and natural materials and other sources for alternatives to fluoride exposure
Highlights Higher fluoride in drinking water is slow poison with irrecoverable consequences. The paper discusses the natural factors behind occurrences of high fluorosis globally. The Global Fluoride Belts are geographically connected and geologically similar with natural factors. In situ process of fluoride removal techniques, their removal capacity, advantages and disadvantages are discussed. Abstract Fluorosis is […]

The chemical resistance and direct contact properties of polymers
Excerpt: … In the 1950s, Procter & Gamble had developed a ground-breaking and revolutionary toothpaste formulation (the first ever ‘fluoride’ toothpaste) to combat tooth decay but were hamstrung in its launch (which P&G christened as fluoristan) that was very aggressive and corrosive. The standard packaging system for toothpaste at that time was the collapsible aluminum […]
