The materials scientists have increased the stability and efficiency of wide-bandgap perovskite solar cells that can be used as the upper part of the tandem solar module. Additive salts of substituted piperidine in the perovskite layer prevents oxidation of anions Read more
Australian the materials scientists have learned to effectively to hydrogen from water without the use of expensive of semiconductor materials. They used the photocathode of textured silicon and combined it with a wide-gap perovskite solar cell, placing solar elements below Read more
American engineers have developed para-aramid fiber with high porosity and amorphous. When combining with the other layers of para-aramide the new material shows a slightly degraded mechanical properties, but is twenty times better thermal insulation properties. In the future it Read more
British and American engineers have developed a simple method of creating a luminous touch surfaces of complex shape. You must first print based on the 3D-printer, and then sprayed on the desired area several layers, including a layer of phosphors Read more
Engineers have created biohybrid chemical synapse, which is secreted by mesenchymal cells dopamine modulated the conductivity of the electrodes neuromorphic device. The mediator irreversibly changed the sensitivity of the postsynaptic unit and simulated long-term potentialy. Article published in the journal Read more
Material engineers developed the thermoelectric Converter on gelatin-based and salts of iron and potassium. Device can transform the warmth of human body electricity record efficiency providing voltage 2.2 volt. It perhaps due to the synergy of the two effects — Read more
Chinese scientists have developed a compact and flexible sensor for monitoring the breathing at the expense of temperature difference between inhaled and exhaled air. It automatically processes the signal and determines respiratory failure. This sensor is suitable for monitoring breathing Read more
Chinese and Finnish material engineers increased stability of nanostructured superhydrophobic material, adding reinforcing the pyramidal microstructure. This by the way, you can make superhydrophobic metal surface, silicon, glass and ceramics, and superhydrophobic properties are stored even after 1000 cycles abrasive Read more
Physicists from the United States and Japan were able to capture the fluctuations of the dimeric fullerenes in carbon nanotubes with a resolution of 0.1 angstroms using electron microscope and high speed camera. In this case, scientists managed to increase Read more
Chinese researchers have found a way to get rid of wrinkles in the graphene layers of paper. To do this, they immerse the material in the plasticizer, stretched, and then was taken out and dried under tension. As a result, Read more
