The National Nanotechnology Initiative defines nanotechnology as the understanding and control of matter at the nanoscale, at dimensions of approximately 1 and 100 nanometers, where unique phenomena enable novel applications. Nanotechnology is taking the world by storm, revolutionizing the materials and devices used in many applications and products. That’s why a finding announced by Xiang-Feng Zhou and Artem R. Oganov, Group of Theoretical Crystallography in the Department of Geosciences, are so significant.

Nanotechnology may provide the key to effective individual dosing with antibiotics according to a new study in the journal Nature Nanotechnology. The study used nanoparticles as surface-stress sensors in order to determine how much of a particular antibiotic target bacteria versus how much is decoyed by competing ligands such as serum proteins. This can vary between individuals, so this type of sensor could help in individualizing drug dosage.

How would electrons behave if confined to a wire so slender they could pass through it only in single-file? The question has intrigued scientists for more than half a century. In 1950, Japanese Nobel Prize winner Sin-Itiro Tomonaga, followed by American physicist Joaquin Mazdak Luttinger in 1963, came up with a mathematical model showing that the effects of one particle on all others in a one-dimensional line would be much greater than in two- or three-dimensional spaces. Among quantum physicists, this model came to be known as the “Luttinger liquid” state.

Flexible, layered materials textured with nanoscale wrinkles could provide a new way of controlling the wavelengths and distribution of waves, whether of sound or light. The new method, developed by researchers at MIT, could eventually find applications from nondestructive testing of materials to sound suppression, and could also provide new insights into soft biological systems and possibly lead to new diagnostic tools.

As smartphones, tablets and other gadgets become smaller and more sophisticated, the heat they generate while in use increases. This is a growing problem because it can cause the electronics inside the gadgets to fail. Conventional wisdom suggests the solution is to keep the guts of these gadgets cool. But a new University at Buffalo research paper hints at the opposite: that is, to make laptops and other portable electronic devices more robust, more heat might be the answer.
