New thirty-minute blood test to reduce sepsis deaths

23 апреля, 2019 - 15:51
A new detector using photonics to identify E. coli bacteria from a tiny drop of blood, and produce a while-you-wait diagnosis in less than thirty minutes is making a bold bid to reduce the mortality rate from sepsis by more than 70%.

Atomic beams shoot straighter via cascading silicon peashooters

23 апреля, 2019 - 15:14
To a non-physicist, an 'atomic beam collimator' may sound like a phaser firing mystical particles. That might not be the worst metaphor to introduce a technology that researchers have now miniaturized, making it more likely to someday land in handheld devices.

Estimating the occurrence of nanomaterials in the environment

23 апреля, 2019 - 15:04
To perform a risk assessment of nanomaterials in the environment, information on the exposure, i.e. the amounts that are present in the environment, is essential. In contrast to many other known pollutants, the concentrations of nanomaterials in environmental systems cannot be measured directly. In this situation, exposure modelling is a solution to estimate the environmental exposure with synthetic nanomaterials. In order to predict the amount of a nanomaterial in a certain environmental compartment (environmental exposure) present in a certain area, two basic types of models are required - material flow analysis and environmental behaviour modelling.

Quantum gas turns supersolid

23 апреля, 2019 - 11:13
Scientists report on the observation of supersolid behavior in dipolar quantum gases of erbium and dysprosium. In the dysprosium gas these properties are unprecedentedly long-lived. This sets the stage for future investigations into the nature of this exotic phase of matter.

Semiconductor scientists discover effect that was thought impossible

22 апреля, 2019 - 18:16
A physical effect known as superinjection underlies modern light-emitting diodes (LEDs) and lasers. For decades this effect was believed to occur only in semiconductor heterostructures. Researchers now have found superinjection to be possible in homostructures, which are made of a single material.

Quantum-material-based proton-irradiation-immune electronics for space travel

22 апреля, 2019 - 11:11
Proton radiation damage is an important failure mechanism for electronic devices in near-Earth orbits and deep space. The future of space exploration depends crucially on the development of new electronic technologies that are immune to space radiation, which consists primarily of protons, electrons, and cosmic rays. The penetrating energetic radiation of deep space produces negative impacts on not only biological entities but also the electronic systems of space vehicles. Researchers have now demonstrated two-dimensional charge-density-wave devices with a remarkable immunity to bombardment with protons.
