Renewable Energy Made by Mixing Salt and Fresh Water

(PhysOrg.com) -- When a river flows into the sea, the location is more than just a haven for water commerce. The mixing of fresh and salt water that occurs at an estuary also dissipates energy, as the different salinity waters ...

A step closer to sustainable energy from seawater

The research group led by Leiden chemist Marc Koper has discovered a catalyst that minimizes the production of chlorine gas during salt water electrolysis. The invention can enable the direct production of hydrogen from seawater. ...

Graphene battery demonstrated to power an LED

(PhysOrg.com) -- Scientists in Hong Kong have reported, in ArXiv, their experiments to make a graphene battery that they say generates an electrical current by drawing on the ambient thermal energy in the solution in which ...

Container rethink: Ooho team cooks up water holder

(Phys.org) —Think about it. A Sunday in the park. Trashbins overflow with plastic water bottles cast off by joggers, power walkers and their cheering supporters. They have gone home after a charitable athletic event to ...

DNA devices perform bio-analytical chemistry inside live cells

Some biochemistry laboratories fashion proteins into complex shapes, constructing the DNA nanotechnological equivalent of Baroque or Rococo architecture. Yamuna Krishnan, however, prefers structurally minimalist devices.

Chloride

The chloride ion is formed when the element chlorine, a halogen, picks up one electron to form an anion (negatively-charged ion) Cl−. The salts of hydrochloric acid HCl contain chloride ions and can also be called chlorides. The chloride ion, and its salts such as sodium chloride, are very soluble in water. It is an essential electrolyte located in all body fluids responsible for maintaining acid/base balance, transmitting nerve impulses and regulating fluid in and out of cells.
