New nanodevice defeats drug resistance

Chemotherapy often shrinks tumors at first, but as cancer cells become resistant to drug treatment, tumors can grow back. A new nanodevice can help overcome that by first blocking the gene that confers drug resistance, then launching a new chemotherapy attack against the disarmed tumors.

Graphene and glass coating improves battery performance

To improve lithium-sulfur batteries, researchers added glass cage-like coating and graphene oxide.

Researchers use lab-scale human colon to study impact of copper nanoparticles on the environment

What do a human colon, septic tank, copper nanoparticles and zebrafish have in common? They were the key components used by researchers to study the impact copper nanoparticles, which are found in everything from paint to cosmetics, have on organisms inadvertently exposed to them.

Pens filled with high-tech inks for do-it-yourself sensors

A new simple tool developed by nanoengineers, is opening the door to an era when anyone will be able to build sensors, anywhere, including physicians in the clinic, patients in their home and soldiers in the field.

Forbidden quantum leaps possible with high-res spectroscopy

A new twist on an old tool lets scientists use light to study and control matter with 1,000 times better resolution and precision than previously possible.

Scientists observe the current flow along nanochannels at the crystal surfaces of topological insulators

Scientists report that they could observe experimentally the current flow along channels at the crystal surfaces of topological insulators. The channels are less than one nanometer wide and extend along atomic steps of the crystal lattice. The scientists demonstrated also how these steps can be introduced in any arrangement.

Breakthrough in OLED technology

A new study shows that OLEDs made with finely patterned structures can produce bright, low-power light sources, a key step toward making organic lasers.
