Steering light with dynamic lens-on-MEMS

Scientists add active control to design capabilities for new lightweight flat optical devices.

Sugar-coated nanosheets selectively target pathogens

Researchers design self-assembling nanosheets that mimic the surface of cells.

A safe and effective way to whiten teeth with nanoparticles

Researchers modified titanium dioxide nanoparticles so that they could be activated with blue light. In a proof-of-concept experiment. After four hours of treatment, the whitening level was similar to that obtained with hydrogen-peroxide-based agents.

Scientists reported on toxicity of carbon and silicon nanotubes and carbon nanofibers

Nanoparticles with a wide range of applying, including medicine, damage cells of microalgae Heterosigma akashivo badly.

Nanoscale imaging yields key insights into water splitting

Researchers are another step closer to reaping fuel from sunlight.

Solar powered synthetic skin for robotics and prosthetics

A new way of harnessing the sun's rays to power synthetic skin could help to create advanced prosthetic limbs capable of returning the sense of touch to amputees.

Automated diagnostic platform that indicates thrombotic risks or cancer in one drop of blood

A team of international researchers developed an automated diagnostic platform that indicates bleeding - and thrombotic risks in one drop of blood within seconds.

Hydrogen from water in iron nanotruss structures

Researchers have discovered a new and efficient way to use electrocatalysis to produce hydrogen gas from water. Instead of using expensive and difficult-to-obtain platinum electrodes, the new method uses electrodes with nanotruss structures of iron oxide.

Materials processing tricks enable engineers to create new laser material

By doping alumina crystals with neodymium ions, engineers have developed a new laser material that is capable of emitting ultra-short, high-power pulses - a combination that could potentially yield smaller, more powerful lasers with superior thermal shock resistance, broad tunability and high-duty cycles.
