Microsoft patents high pressure data center
Hermetically sealed data centers for efficient heat transfer Microsoft has been awarded a high pressure data center patent that would allow for far more efficient heat transfer than traditional approaches. “Some data centers employ heat sinks and electric fans (which can consume a substantial amount of energy),” the filing (Patent US10426062) states. “In cases of […]

Grid switchgear uses SF6, the world’s most potent greenhouse gas. How do we regulate it?
Sulphur Hexafluoride (SF6) is described as the world’s worst greenhouse gas. It’s 23,500 times more potent than CO2. Global annual emissions are 8,100 tonnes, equivalent to the CO2 emissions of 100m cars. It has an atmospheric lifetime of over 1,000 years and its installed base is expected to grow by 75% by 2030. 80% of […]

WHO: Fluorosis
The disease and how it affects people Ingestion of excess fluoride, most commonly in drinking-water, can cause fluorosis which affects the teeth and bones. Moderate amounts lead to dental effects, but long-term ingestion of large amounts can lead to potentially severe skeletal problems. Paradoxically, low levels of fluoride intake help to prevent dental caries. The […]

One-step synthesis of zirconium dioxide-biochar derived from Camellia oleifera seed shell with enhanced removal capacity for fluoride from water.
Note from Fluoride Action Network: “Since all methods [to remove fluoride] produce a sludge with very high concentration of fluoride that has to be disposed of, only water for drinking and cooking purposes should be treated, particularly in the developing countries.” Reference: Fluorosis (see Interventions), World Health Organization Highlights Camellia seed shell waste was calcined […]

Fluoride reactivation-enabled sensitive quantification of tabun adducts on human serum albumin by GC-MS/MS via isotope dilution.
Organophosphorus nerve agents inhibit the cholinesterase activity by phosphylation of the active site serine. The resulting phosphylated cholinesterase and adducts on human serum albumin (HSA) are appropriate biomarkers for nerve agents exposure. Several methods have been developed for the detection of nerve agents, including fluoride reactivation or alkaline cleavage. It was previously thought that some […]

Bubbles and Dust: Experimental Results of Dissolution Rates of Metal Salts and Glasses From Volcanic Ash Deposits in Terms of Surface Area, Chemistry, and Human Health Impacts.
Abstract Explosive volcanic eruptions lead to ash deposition and subsequent leaching of contaminants into soils or surface water, impacting flora and fauna, including human health. This study determined the control of ash surface area and chemical composition on ash dissolution rates. Fresh, unhydrated ash samples from four contrasting volcanoes were analyzed in the laboratory. Column […]

Some Types of Tea Can Harm Your Health
Next to water, tea is the most popular beverage in the world and for good reason. Numerous studies have linked the consumption of tea to reduced cancer and cardiovascular risks as well as a way to prevent Alzheimer’s disease. But despite its well-researched health benefits, some scientists warn that sipping certain varieties of teas can […]

Simplified Batch and Fixed-Bed Design System for Efficient and Sustainable Fluoride Removal from Water Using Slow Pyrolyzed Okra Stem and Black Gram Straw Biochars
Abstract Okra stem biochar (OSBC) and black gram straw biochar (BGSBC) were prepared by slow pyrolysis at 500 and 600 °C, respectively. OSBC and BGSBC were characterized using SBET, Fourier transform infrared, X-ray diffraction, scanning electron microscopy (SEM), transmission electron microscopy, SEM–energy dispersive X-ray, and energy dispersive X-ray fluorescence. High carbon contents (dry basis) of […]

Hydrolysis of Formyl Fluoride Catalyzed by Sulfuric Acid and Formic Acid in the Atmosphere.
Abstract Formyl fluoride (HFCO) is an important atmospheric molecule, and its reaction with the OH radical is an important pathway when degradation of HFCO is considered in earth’s troposphere. Here, we study the hydrolysis of formyl fluoride (HFCO + H2O) with sulfuric acid (H2SO4) and formic acid (HCOOH) acting as catalysts by utilizing M06-2X, CCSD(T)-F12a, […]
