ACS Nano
Eavesdropping on lithium ions
It's a jungle down there at batteries' atomic level, with ions whacking into electrodes, eventually causing the battery to fail. Now, a Michigan Technological University scientist has developed a device that lets researchers spy on the actions of lithium ions inside a nanobattery -- and use that data to develop better, longer-lasting batteries to power everything from electric cars to cell phones.

Molecular chains hypersensitive to magnetic fields
Researchers have for the first time created perfect one-dimensional molecular wires of which the electrical conductivity can almost entirely be suppressed by a weak magnetic field at room temperature. The underlying mechanism is possibly closely related to the biological compass used by some migratory birds. This spectacular discovery may lead to radically new magnetic field sensors, for smartphones for example. The leading scientific journal Science publishes the research results on 4 July.

Antifreeze, cheap materials may lead to low-cost solar energy
A process combining some comparatively cheap materials and the same antifreeze that keeps an automobile radiator from freezing in cold weather may be the key to making solar cells that cost less and avoid toxic compounds, while further expanding the use of solar energy.

Tiny tweezers allow precision control of enzymes
Hao Yan and his colleagues at Arizona State University's Biodesign Institute describe a pair of tweezers shrunk down to an astonishingly tiny scale. The group demonstrated that the nanotweezers, fabricated by means of the base-pairing properties of DNA, could be used to keep biological molecules spatially separated or to bring them together as chemical reactants, depending on the open or closed state of the tweezers.

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.
