Nanoscale ultrasound technique is first to image inside live cells

Scientists have developed a break-through technique that uses sound rather than light to see inside live cells, with potential application in stem-cell transplants and cancer diagnosis.

How to tell when a nanoparticle is out of shape

New method ensures that measurements are well-rounded.

Nanoarray sniffs out and distinguishes multiple diseases

Researchers report that they have identified a unique 'breathprint' for each disease. Using this information, they have designed a device that screens breath samples to classify and diagnose several types of diseases.

New material with ferroelectricity and ferromagnetism may lead to better computer memory

Multiferroic materials exhibit both ferromagnetism and ferroelectricity. These are expected to be used as multiple-state memory devices. Furthermore, if the two orders are strongly coupled and the magnetization can be reversed by applying an external electric field, the material should work as a form of low power consumption magnetic memory.

Graphene able to transport huge currents on the nanoscale

New experiments have shown that it is possible for extremely high currents to pass through graphene, a form of carbon. This allows imbalances in electric charge to be rapidly rectified.

A brand-new way to synthesize sodium-embedded carbon nanowalls for electrodes

Scientists created a brand-new way to synthesize sodium-embedded carbon nanowalls. Previously, the material was only theoretical.

Coffee-ring phenomenon explained in new theory

Scientists have modeled how a colloidal droplet evaporates and found a previously overlooked mechanism that more accurately determines the dynamics of particle deposition in evaporating sessile droplets, which has ramifications in many fields of today's technological world.
