At ambient pressure there are 29 elemental superconductors in the periodic table, none of which is an alkali metal. The first alkali metal to become superconducting under high pressure is Cs followed years later by Li. Alkali metals are believed to be exemplary free-electron systems. The fact that an alkali metal becomes superconducting at all is surprising and is a result of the fact that unde...

The Front Cover shows the CO2 chemisorption behavior of coordination-derived phenolate sorbents. Phenolate-based systems were constructed via coordination between alkali metal cations (Li+ or Na+) with crown ethers to avoid participation active protons in chemisorption. uptake could be achieved by O−C bond formation afford carbonate. capacity and reaction enthalpy significantly influenced effec...

1. The deposition of casein on a platinum anode which takes place on the passage of a direct current through solutions of alkali caseinates was quantitatively studied, and it was found that: (a) the amount of casein which is deposited is directly proportional to the current, i.e. it obeys Faraday's law; (b) the amount of casein deposited is inversely proportional (within the limits studied) to ...

All living organisms require nutrient minerals for growth and have developed mechanisms to acquire, utilize, and store nutrient minerals effectively. In the aqueous cellular environment, these elements exist as charged ions that, together with protons and hydroxide ions, facilitate biochemical reactions and establish the electrochemical gradients across membranes that drive cellular processes s...

The complexation and selective transport of alkaline earth metal cations in general and Ba in particular have been thoroughly investigated for a long time. Important applications for Ba extraction include the purification of spent nuclear fuel as well as sulfur analytics. Various binding domains have been successfully established, e.g. calixarenes, cyclic oligopeptides or substituted crown ethe...

Abstract We present a new rigid-ion force-field for the alkali metal nitrates that is suitable simulating solution chemistry, crystallisation and polymorphism. show it gives good representation of crystal structures, lattice energies, elastic dielectric properties these compounds over wide range temperatures. Since all are fitted together using common model nitrate anion, also solid solutions. ...

Ionic Polymer-metal Composites (IPMCs) are soft actuators and sensors. They generally consist of a thin perfluorinated ionomer membrane, metal electrodes plated on both faces, and are neutralized with certain counter cations, balancing the charge of the anions covalently fixed to the membrane. Under a suddenly applied step function (1 to 3 V), the IPMC in alkali-metal cation forms exhibits a fa...
