Covalent organic framework-based ultrathin crystalline porous film: manipulating uniformity of fluoride distribution for stabilizing lithium metal anode

In situ formed LiF grains are confined and evenly distributed throughout a covalent organic framework (COF) film, which exhibits cooperative effectiveness to greatly stabilize the lithium metal.

Fluoride Distribution in Aquatic Environment in Vicinity of Aluminum Industry and Its Correlation with Rainwater Chemistry and Weather Parameter: A Case Study of Renukoot, District Sonbhadra, Uttar Pradesh, India

Fluorine is a highly reactive element and readily hydrolyzes to form hydrogen fluoride and oxygen. Hydrogen fluoride reacts with many materials both in the vapor phase and in aerosols. Fluorides are naturally-occurring components of rocks and soil and are also found in air, water, plants, and animals. Fluorine gas pollutes the atmospheric environment originating from aluminium smelting plant operating at Renukoot, district Shonbhadra. Volcanic emissions also emit hydrogen fluoride. A detailed investigation undertaken during 2008-2012 to objective fluoride Distribution in Aquatic Environment in Vicinity of Aluminum Industry and its Correlation with Rainwater Chemistry and Weather Parameter. For this investigation Collect 57 rainwater samples in rainy season in pre-cleaned and sterilized polyethylene bottles of two litre capacities from roof of the local society of Hindustan Aluminum Company Renukoot, district Sonbhadra. The collected samples were analyzed for pH, Electrical Conductivity, Sodium, Potassium, Calcium, Carbonates, Bicarbonates, Chlorine, Sulphate, Fluoride, Residual Sodium Carbonates, and Sodium Adsorption Ratio with standard procedures.
