Chemists work to desalt the ocean for drinking water, 1 nanoliter at a time
By creating a small electrical field that removes salts from seawater, chemists have introduced a new method for the desalination of seawater that consumes less energy and is dramatically simpler than conventional techniques. The new method requires so little energy that it can run on a store-bought battery.

Polymer coatings a key step toward oral delivery of protein-based drugs
In a new study, a "bioadhesive" coating developed at Brown University significantly improved the intestinal absorption into the bloodstream of nanoparticles that someday could carry protein drugs such as insulin. Such a step is necessary for drugs taken by mouth, rather than injected directly into the blood.

Spinning up antibacterial silver on glass
The antibacterial effects of silver are well established. Now, researchers at Yonsei University in Seoul, Republic of Korea, have developed a technique to coat glass with a layer of silver ions that can prevent growth of pathogenic bacteria including Escherichia coli, Salmonella typhimurium and Campylobacter jejuni. The technology could be used to protect medical equipment and be particularly useful for applications in disaster recovery and the military environment.

Ingested nanoparticle toxicity
Ingestion of commonly encountered nanoparticles at typical environmental levels is unlikely to cause overt toxicity, according to US researchers. Nevertheless there is insufficient evidence to determine whether chronic exposures could lead to subtle alterations in intestinal immune function, protein profiles, or microbial balance.

Quantum engines must break down
Our present understanding of thermodynamics is fundamentally incorrect if applied to small systems and need to be modified, according to new research from University College London and the University of Gdansk. The work, establishes new laws in the rapidly emerging field of quantum thermodynamics. The findings, published today in Nature Communications, have wide applications in small systems, from nanoscale engines and quantum technologies, to biological motors and systems found in the body.

Efficient production process for coveted nanocrystals
A formation mechanism of nanocrystalline cerium dioxide (CeO2), a versatile nanomaterial, has been unveiled by scientists from the Helmholtz-Zentrum Dresden-Rossendorf and the University of New South Wales in Sydney, Australia. The research results were published in the scientific journal Chemistry - A European Journal. This finding potentially simplifies and alleviates the existing synthetic processes of nanocrystalline CeO2 production.
