To generate electric current, two particles must separate in spite of being bound together closely. These two particles, electron and electron-hole, together form an exciton. The higher mobile excitons can achieve more efficient charge separation. ...
Scientists have created super-strong aluminum alloy by introducing faults into its crystalline structure. It would have a wide range of applications including corrosion resistant coating for vehicles and electronic instruments. The study helps us...
When your eyes move, so do your eardrums. The movements of eardrum encode spatial information about the movements of eyes, and this helps our brain to merge visual and auditory space. The study could help us better understand disorders ranging...
They reflectivity of ultra-thin material, molybdenum diselenide (MoSe2), can be adjusted with an applied voltage. MoSe2 shows high reflectivity for specific wavelengths of light. Reflectivity can be changed by adjusting the material’s...
Scientists developed a technique that cools down water to minimum 228 Kelvin without making it freeze. The tinier the drop, the colder it could get while being in liquid phase. They used laser pulses to monitor the size of drops and to measure the...
How your brain reacts while listening music can reveal whether you’re a musician or not. Researchers utilized fMRI brain data and applied different computational methods to extract special features of presented music. The machine learning...
Researchers have developed a free-space volumetric display technique based on photophoretic optical trapping. It can produce image geometries that are currently unachievable with holograms and light-field technologies. So far, they have projected...
Physicists have made transparent material ‘virtually’ absorb light under certain conditions. They studied a thin layer of transparent dielectric and measured the sufficient intensity required for absorbing incident beam of light. When...
Scientists build transistor-free analog switching devices using silicon germanium. The small artificial synapses chip can recognize samples of handwriting, with 95% accuracy. It aims to eliminate the limited scalability of current neuromorphic...
Scientists observe high intensity light emitting from individual graphene nanoribbons. It’s 100 times more intense than the previous single-molecular optoelectronic device. The color of light, emitted by 7-atom-wide nanoribbons, can be altered...
Scientists develop a new technique for controlling the nanorobotic arms by applying electric fields. The electrical control can be implemented with low-cost instrumentation and it’s contact-free. In future the technology could be utilized in...
Microsoft’s new drawing bot can create any picture using text-description and captions. It consists of two machine learning models – generator and discriminator. The AI can even draw details that are not described, using its own...
