Study reveals the Great Pyramid of Giza can focus electromagnetic energy

01/08/2018

An international research group applied methods of theoretical physics to investigate the electromagnetic response of the Great Pyramid to radio waves. Scientists predicted that under resonance conditions the pyramid can concentrate electromagnetic energy in its internal chambers and under the base.

Drexel's polymer pill proves it can deliver

01/08/2018

Selecting the right packaging to get precious cargo from point A to point B can be a daunting task. Scientists have wrestled with a similar set of questions when packaging medicine for delivery in the bloodstream: How much packing will keep it safe? Is it the right packing material? Is it too big? Is it too heavy? Researchers ...

Made-to-measure silicon building blocks

31/07/2018

Silicones are synthetic materials used in a broad range of applications. Thanks to the stability of the silicon-oxygen bond, they are resistant to chemicals and environmental influences and also harmless from a physiological point of view. As a result, silicones contribute to making everyday life easier in almost all areas. In the Journal of the ...

Hydrogen and plastic production: New catalyst with a dual function

30/07/2018

Chemists at Ruhr-Universität Bochum (RUB) have developed a new, low-cost catalyst for plastic production. It turns a biorefinery product into a starting material for the synthesis of plastics, which could represent a sustainable alternative to widespread PET. At the same time, the potential energy source hydrogen can also be formed during the reaction.

Generation of random numbers by measuring phase fluctuations from a laser diode with a silicon-on-in

27/07/2018

Researchers have shown that a chip-based device measuring a millimeter square could be used to generate quantum-based random numbers at gigabit per second speeds. The tiny device requires little power and could enable stand-alone random number generators or be incorporated into laptops and smart phones to offer real-time encryption.

Scientists develop new materials that move in response to light

26/07/2018

Researchers at Tufts University School of Engineering have developed magnetic elastomeric composites that move in different ways when exposed to light, raising the possibility that these materials could enable a wide range of products that perform simple to complex movements, from tiny engines and valves to solar arrays that bend toward the sunlight. The research is described in an ...

Materials scientists of Lomonosov MSU proposed a novel approach for obtaining films for solar cells

25/07/2018

Scientists of the Lomonosov Moscow State University explained the key mechanisms of interaction of hybrid perovskites with solvents and suggested new approaches to obtain perovskite light-absorbing layers for thin-film solar cells from weakly coordinating aprotic solvents. The results of the study have been recently published in the high-rating journal Chemistry of Materials.

Materials processing tricks enable engineers to create new laser material

23/07/2018

By doping alumina crystals with neodymium ions, engineers at the University of California San Diego 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.
