Iridium is attractive for improving flash memory chips

One of the rarest metals on Earth may be an excellent option for enabling future flash memory chips to continue increasing in speed and density, according to a group of researchers in Taiwan, who describe incorporating nanocrystals of iridium into critical components of flash memory.

Making wafers faster by making features smaller

Manufacturing semiconductors for electronics involves etching small features onto wafers using lasers, a process that is limited by the wavelength of the light itself. The development of a new, intense 13.5-nm light source will resolve this issue by reducing the feature size by an order of magnitude or so.

Single quantum dot nanowire photodetectors

Moving a step closer toward quantum computing, a research team in the Netherlands recently fabricated a photodetector based on a single nanowire, in which the active element is a single quantum dot with a volume of a mere 7,000 cubic nanometers.

The role of engineering in the study of infectious disease

Although engineering has long played a key role in developing technology for diagnosing and treating human disease, it has only recently started to have an impact on understanding the cellular and molecular basis of disease. In the past decade or so, engineers have started making major contributions to understanding diseases such as malaria, hereditary blood diseases and cancer, according to Subra Suresh, former dean of MIT's School of Engineering.

Novel tailor-made nanoferroelectric from building blocks

A research group headed by MANA Scientist Dr. Minoru Osada and Principal Investigator Dr. Takayoshi Sasaki of the International Center for Materials Nanoarchitectonics (MANA) at the National Institute for Materials Science (NIMS) successfully developed a novel nanoferroelectric by a solution-based bottom-up nanotechnology.

Tiny channels carry big information

Researchers with Lawrence Berkeley National Laboratory have been able to fabricate nanochannels that are only two nanometers in size, using standard semiconductor manufacturing processes. Already they've used these nanochannels to discover that fluid mechanics for passages this small are significantly different not only from bulk-sized channels, but even from channels that are merely 10 nanometers in size.

Taking the temperature of a molecule

You can touch a functioning light bulb and know right away that it's hot. Ouch! But you can't touch a single molecule and get the same feedback. Rice University researchers say they have the next best thing -- a way to determine the temperature of a molecule or flowing electrons by using Raman spectroscopy combined with an optical antenna.

Magnetism relieves electrons of their resistance

Physics is sometimes just like a criminal investigation. Researchers gather one piece of evidence after another in order to solve a mystery - for example, the question as to how unconventional superconductivity is caused, something which is also of particular interest for technical applications. An international team involving scientists at the Max Planck Institute for Chemical Physics of Solids has now provided the strongest evidence yet that magnetic interactions can bring about this form of zero-resistance current transport - something that physicists have been gathering evidence for, for some time.

Alternating stacks of planar cations and dipyrrole-containing anions provides concept for new materials

Pyrroles, which are rings containing one nitrogen and four carbon atoms, are essential components of our red hemoglobin as well as the green chlorophyll in plants. Japanese researchers have now also used this molecular motif in the construction of new nanostructured materials: They combined planar pyrrole-containing negatively charged complexes with similarly planar, positively charged organic ions.
