Using Nanotechnology to Tame Alkali Metals
|
Sodium and other alkali metals readily give up their electrons in chemical reactions, making them extremely useful throughout a wide variety of chemical-based industries. Unfortunately, they also tend to burst into flames when exposed to moisture or air, making them extremely dangerous to handle and store, and thus limiting their use-until now - thanks to Michael Lefenfeld, president and chief scientific officer (CSO) of SiGNa Chemistry LLC, and the firm's vice president of R&D, James Dye...

Alkalies, Chlorides, Seawater, and ASR
Concrete International
; Is there an increased likelihood of a harmful alkali-silica reaction in concrete exposed to seawater? There is a mistaken notion that potentially reactive aggregates shouldn't be used in concrete exposed to seawater. This notion is stated twice in ACI 201.2R-01, "Guide to Durable Concrete."1

The role of sodium perfluorobutyrate in promoting the antioxidancy of DODPA in synthetic esters
Tribology Transactions
; Differential scanning calorimetry (DSC) and oxidation-corrosion tests were employed to evaluate the inhibition of pentaerythritol ester containing sodium perfluorobutyrate (C^sub 3^F^sub 7^COONa) towards oxidation. The results show that C^sub 3^F^sub 7^COONa enhances antioxidancy of

Metal rebel: under extreme pressure, sodium breaks the rules for turning into liquid.(This Week)
Science News
; In a demonstration that defies basic assumptions in physics, researchers have created liquid sodium at room temperature. As a member of the alkali metals--the first column in the periodic table--sodium is considered to be one of the simplest metals. Under normal conditions, it melts at about

METAL CHLORIDE REDUCTIONS WITH AROMATIC RADICAL ANIONS. THE MAGNESIUM CHLORIDE CATALYSED CLEAVAGE OF TETRAHYDROFURAN BY SODIUM NAPHTHALENE RADICAL ANION
Collection of Czechoslovak Chemical Communications
; Activated metals for organic synthesis are often prepared by reduction of metal salts using alkali metal aromatic radical anions. The reduction of magnesium chloride has been examined by NMR. Whereas the expected reduction to the metal occurred with lithium or potassium naphthalene radical anion,
