Chemical treatment improves quantum dot lasers

16 октября, 2017 - 20:26
One of the secrets to making tiny laser devices such as opthalmic surgery scalpels work even more efficiently is the use of tiny semiconductor particles, called quantum dots. In new research the ~nanometer-sized dots are being doctored, or 'doped,' with additional electrons, a treatment that nudges the dots ever closer to producing the desired laser light with less stimulation and energy loss.

Purple power: Synthetic 'purple membranes' transform sunlight to hydrogen fuel

13 октября, 2017 - 16:19
A new way has been found to produce solar fuels by developing “synthetic purple membranes.” These membranes involve an assembly of lipid nanodiscs, man-made proteins, and semiconducting nanoparticles that, when taken together, can transform sunlight into hydrogen fuel.

Mantis shrimp-inspired camera enables glimpse into hidden world

13 октября, 2017 - 03:02
By mimicking the eye of the mantis shrimp, researchers have developed an ultra-sensitive camera capable of sensing both color and polarization. The bioinspired imager can potentially improve early cancer detection and help provide a new understanding of underwater phenomena, the researchers said. See a video of describing the study on YouTube.

Experimental 'nano-chemo' particle to treat bladder cancer

12 октября, 2017 - 17:37
Working with mice and rats, researchers have developed a way to successfully deliver nano-sized, platinum-based chemotherapy drugs to treat a form of bladder cancer called nonmuscle-invasive that is found in the lining of the organ and has not invaded deeper into bladder tissue. The tiny drug-infused particles, they say, potentially offer a less toxic clinical alternative to standard chemotherapy delivered intravenously or through a catheter inserted into the bladder.

The secret to improving liquid crystal's mechanical performance

11 октября, 2017 - 17:07
Researchers have theoretically calculated the static and dynamical properties of the Cottrell clouds, which form around edge dislocations in liquid crystals of the smectic A variety. This work could help, for example, to improve the lubricating performance of such liquid crystals.

Machine learning translates 'hidden' information to reveal chemistry in action

10 октября, 2017 - 19:41
Scientists have developed a new way to capture the details of chemistry choreography as it happens. The method -- which relies on computers that have learned to recognize hidden signs of the steps -- should help them improve the performance of catalysts to drive reactions toward desired products faster.

Forget about it: A material that mimics the brain

10 октября, 2017 - 19:40
Inspired by human forgetfulness -- how our brains discard unnecessary data to make room for new information -- scientists conducted a recent study that combined supercomputer simulation and X-ray characterization of a material that gradually 'forgets.' This could one day be used for advanced bio-inspired computing.

Energy against the current on a quantum scale, without contradicting the laws of physics

6 октября, 2017 - 18:23
In a classical thermodynamic system, the heat current flows from the hotter body to the colder one, or electricity from the higher voltage to the lower one. The same thing happens in quantum systems, but this state can be changed, and the flow of energy and particles can be reversed if a quantum observer is inserted into the system.

Paper-based supercapacitor uses metal nanoparticles to boost energy density

5 октября, 2017 - 19:10
Using a simple layer-by-layer coating technique, researchers have developed a paper-based flexible supercapacitor that could be used to help power wearable devices. The device uses metallic nanoparticles to coat cellulose fibers in the paper, creating supercapacitor electrodes with high energy and power densities -- and the best performance so far in a textile-based supercapacitor.
