Silver nanoparticles in clothing wash out – and may

Many socks, towels and other textiles are treated with silver nanoparticles to kill germs and odors. When the silver washes out, it can pollute waterways. Two chemists propose a way to collect it

A united residue force-field for calcium-protein

Calcium-binding proteins play many biological roles. They are involved in regulation, merane-related events, and muscle movement and act as biological switches (Frausto da Silva et al. 1991; Bertini et al. 1994; Lippard and Berg 1994; Hanna and Doudna 2000).Metal ions, in general, bind to centers of high hydrophilicity and reduce the enthalpy of a system upon binding (Frausto da Silva et

electronic structures of atoms - chemguide

2016-5-29 · We are working out the electronic structures of the atoms using the Aufbau ("building up") Principle. So far we have got to calcium with a structure of 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2. The 4s level is now full, and the structures of the next atoms show electrons gradually filling up the 3d level. These are known as d-block elements.
