Fast, efficient fluorine-based desalination membrane to purify saltwater
Clean water scarcity is a major issue in today’s world, and the problem is only going to worsen with a changing climate. Desalinating brackish water or seawater is an established method to produce drinkable water, but it comes with huge energy costs. There’s no shortage of creative devices in the works, either using heat to […]

Corvallis upholds H&V decision that may lead to air emissions discharge permit
Background from 2015 report: “The modified permit allowed Evanite — and later H&V [Hollingsworth & Vose] — to discharge up to 98 tons of nitrogen oxide, 21 tons of carbon monoxide and 2.8 tons of gaseous fluorides each year at the south Corvallis site. “No testing for those emissions was required or performed at the […]

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 […]

Scenario, perspectives and mechanism of arsenic and fluoride Co-occurrence in the groundwater: A review.
Highlights First review on co-occurrence perspectives of Arsenic and Fluoride in the groundwater. As and F co-occurrences is quite common yet concealed owing to one being dominant. Arid areas are more suitable for co-occurrence with few reports in the Alluvium plains. Local hydro-geochemical processes and seasonality greatly affect co-contamination. Co-contamination can have severe health and […]

Fluoridation of a lizard bone embedded in Dominican amber suggests open-system behavior
*Read original study online at http://fluoridealert.org/wp-content/uploads/barthel-2020.pdf Introduction Fossil bones represent valuable paleontological archives for reconstructing the paleobiology and -environments of vertebrates throughout geological time and thus also represent an important window into the evolution of life on Earth. The preservation of organisms or parts of them over long geological timescales requires exceptional conditions before and […]

Demand increasing for boiler cleaning
There has been a significant increase in demand for industrial and chemical cleaning solutions provider Gra-Tech’s chemical cleaning of package boilers, as industries in which package boilers are used are looking to optimise operational efficiencies and reduce costs. Package boilers are smaller output boilers than those used in general industry. These differ from traditional boilers […]

Astronomers map new emission line to trace most common molecule in the universe
Molecular hydrogen (H2) makes up 99 percent of the cold, dense gas in galaxies. So mapping where stars are born basically means measuring H2, which lacks a strong characteristic signature at low temperatures. Astronomers from SRON Netherlands Institute for Space Research and the University of Groningen have now mapped an emission signal from the trace […]

Origin of hydrogen fluoride emission in the Orion Bar. An excellent tracer for CO-dark H2 gas clouds
Abstract Context. The hydrogen fluoride (HF) molecule is seen in absorption in the interstellar medium (ISM) along many lines of sight. Surprisingly, it is observed in emission toward the Orion Bar, which is an interface between the ionized region around the Orion Trapezium stars and the Orion molecular cloud. Aims. We aim to understand the […]

Fluorine: the T rex of the periodic table
Pass out the nickel superalloy reactor kit, it’s time to tame that most reactive of elements Our lives in the laboratory are seemingly defined by simple borosilicate glass. There are glass flasks, glass columns and glass condensers. It’s gorgeous: a brilliant and transparent material that feels good to the touch and allows you to see […]
