Why providing alternatives to SF6 and other greenhouse gases is important for carbon reduction initiatives
More companies have committed to renewable energy, energy efficiency, and electric vehicle adoption. The urgency to act on climate change has never been greater, and, in the absence of global regulation, companies are voluntarily stepping up to fill the gap. As of the publication of this blog post, more than 1000 companies have set public […]

New Exotic Isotope of Fluorine Discovered: Fluorine-13
Fluorine is the chemical element with the symbol F and atomic number 9. It is the most chemically reactive element on the periodic table and the lightest member of the halogen elements. At standard conditions fluorine exists as a highly toxic, pale yellow diatomic gas. It has 18 known isotopes ranging from 13F to 31F […]

Novel aluminium (hydr) oxide-functionalized activated carbon derived from Raffia palm (Raphia hookeri) shells: Augmentation of its adsorptive properties for efficient fluoride uptake in aqueous media
Highlights RPSAC and ACRPSAC synthesized from Raffia palm shell biomass. ACPSAC had enhanced porosity and BET-surface area of 715.80 mg/g. Adsorptive removal performance of adsorbents for fluoride compared. Excellent fluoride adsorption capacity of 4.10 mg/g for ACRPSAC. Fluoride adsorption describes well with Langmuir model. Regeneration of ACRPSAC possible by recoating with Aluminium (hydr) oxide. Abstract […]

NRK and Expressen Report Fluoro Testing Device Flawed
But what happens in the wax bus matters too: Sweden’s biathlon wax bus flexes. (Photo: NordicFocus) Over the past few years, FasterSkier has reported on per-fluorinated waxes, powders, liquids, and pastes. Entities like the Environmental Protection Agency (EPA) and Europe’s equivalent, the European Environment Agency, are phasing out eight-chain fluorocarbons. We know, after diving into […]

Fluoride removal by thermally treated egg shells with high adsorption capacity, low cost, and easy acquisition
In this study, the use of eggshells was suggested as an adsorbent for fluoride removal, and their mechanism of fluoride removal was investigated. The eggshells underwent thermal treatment to improve their adsorption capacity; 800 °C was found to be the optimal temperature for treatment. Eggshells thermally treated at 800 °C (ES-800) were mainly composed of […]

Community Water Fluoridation: Caveats to Implement Justice in Public Oral Health
Original article online at https://www.mdpi.com/1660-4601/18/5/2372/htm Abstract Community water fluoridation (CWF), a long-established public health intervention, has been studied for scientific evidence from both of yea and nay standpoints. To justify CWF with scientific evidence inevitably leads to ethical justification, which raises the question of whether oral health is of individual concern or social responsibility. As […]

Removal of fluoride from industrial wastewater by using different adsorbents: A review.
Highlights Sources of high fluoride industrial wastewater were summarized. Several kinds of adsorbents were reported in this literature. Four methods were put forward to enhance the performance of adsorbents. Some outlooks for removing fluoride from water by adsorption were advised in the future. Abstract Many industries such as iron and steel metallurgy, copper and zinc […]
