Abstract In the present study, the straw ash (SA) was proposed to remove phosphate and fluoride from aqueous solution. The effects of SA dosage, initial contaminants concentration and initial pH on removal efficiency, adsorption kinetics and isotherms were investigated in batch experiments. The removal mechanisms were also discussed. The results show that solution pH was […]

The controversial contribution to dental research made by Albert Schatz-Co-discoverer of streptomycin
Abstract In addition to being co-discoverer of the antibiotic streptomycin the American microbiologist and soil scientist, Albert Schatz did ground breaking dental research. His major contribution is the Proteolysis–Chelation theory, but he also did research on fluoridation where he emphasised the overlooked involvement of so-called paradoxical effects. His research led him to become an active […]
Adsorptive removal of fluoride using biochar – a potential application in drinking water treatment
Highlights Elevated fluoride levels in drinking water root cause of dental and skeletal fluorosis. The Defluoridation capacity using water melon rind biochar(WMRBC was 9.5 mg/g. Anions such as Cl–, NO3–, SO42, HCO3–and CO32-did not affect fluoride adsorption. Abstract Fluoride as a geogenic contaminant is commonly encountered in groundwater-based drinking water sources. In the present study […]
Sugar is the only cause of tooth decay
Title of article: An Ancient Roman Diet Could Mean a Healthier You Note from Fluoride Action Network: Also see Sugar Is the Only Cause of Tooth Decay, Study Says, Time Magazine, September 16, 2014 Cancer, diabetes, premature aging. It may be sweet to eat, but sugar is disastrous to our bodily systems. Studies show that […]
Evaluation and DFT analysis of 3D porous rhombohedral Fe-modified MgO for removing fluoride efficiently
Highlights Calcination of Fe-modified MgO (CMF) was investigated for fluoride treatment. Electrostatic attraction, ion exchange, and hydrogen bonding are adsorption mechanisms. Fluoride was adsorbed at a low concentration (10 mg/L) with 95.2% removal rate. Theoretical adsorption capacity was 126.79 mg/g. DFT results explain the bonding mode of fluoride and the adsorbent. Abstract Three-dimensional porous rhombohedral […]
A dual-channel optical chemical sensing system for selective detection of nerve agent simulant DFP
Abstract This paper reports a novel optical chemical sensing system for selective detection of diisopropylfluorophosphate (DFP), a simulant of fluorine-containing nerve agents (Sarin and Soman). Contrary to the reported methods involving only single sensing probe, this sensing system is comprised of two molecular sensing probes (1 and 2) having intrinsic affinities for reactive subunits of […]

Comprehensive and critical appraisal of plant-based defluoridation from environmental matrices
Highlights State of the art presented on the use of various bioadsorbents and plants in defluoridation. Effect of parameters such as pH, temperature and kinetics is discussed. Overview of F– adsorption mechanisms, thermodynamic studies and uptake mechanisms. Exploration and selection of low-cost adsorbents and phytoremediators is required. Necessity of modification and commercialisation of specific adsorbents […]
Molten Salt Reactors
(Updated May 2021) Molten salt reactors operated in the 1960s. They are seen as a promising technology today principally as a thorium fuel cycle prospect or for using spent LWR fuel. A variety of designs is being developed, some as fast neutron types. Global research is currently led by China. Some have solid fuel similar […]
GE, Hitachi ABB in bid to cut greenhouse gas emissions
GE Renewable Energy’s Grid Solutions business and Hitachi ABB Power Grids have signed a non-exclusive, cross-licensing agreement related to the use of an alternative gas to sulfur hexafluoride (SF6) used in high voltage equipment. This fluoronitrile-based gas mixture has a significantly reduced impact on the environment compared to SF6 Under this landmark agreement announced just […]
