Scientists achieve first ever acceleration of electrons in plasma waves Posted: 14 Oct 2018 11:27 AM PDT Researchers have demonstrated a new technique for accelerating electrons to very high energies over short distances. |
Fast, accurate estimation of the Earth's magnetic field for natural disaster detection Posted: 14 Oct 2018 11:27 AM PDT Researchers have applied machine-learning techniques to achieve fast, accurate estimates of local geomagnetic fields using data taken at multiple observation points, potentially allowing detection of changes caused by earthquakes and tsunamis. A deep neural network (DNN) model was developed and trained using existing data; the result is a fast, efficient method for estimating magnetic fields for unprecedentedly early detection of natural disasters. This is vital for developing effective warning systems that might help reduce casualties and widespread damage. |
Efficiently turning light into electricity Posted: 11 Oct 2018 07:37 AM PDT Perovskites form a group of crystals that have many promising properties for applications in nano-technology. However, one useful property that so far was unobserved in perovskites is so-called carrier multiplication -- an effect that makes materials much more efficient in converting light into electricity. New research has now shown that certain perovskites in fact do have this desirable property. |
New technique for turning sunshine and water into hydrogen fuel Posted: 11 Oct 2018 07:36 AM PDT Researchers have developed new photocatalyst synthesis method using Magnesium hydride (MgH2) and Titanium dioxide (TiO2). The result is expected to contribute to hydrogen mass production through the development of photocatalyst that reacts to solar light. |
A new cancer weapon: Antibodies Posted: 11 Oct 2018 07:36 AM PDT Engineers haVE proposed a novel approach to antibody-based imaging of cancer, using ultrasmall silica nanoparticles -- better known as 'Cornell dots' (or C dots). |
Posted: 11 Oct 2018 06:04 AM PDT What if your theory to model and predict the electronic structure of atoms isn't accounting for dispersion energy? You come up with some 'fudge factors' to make it all work. But getting the right results for the wrong reasons can only take you so far. |
