This new treatment involves stimulation of neurons deep within the brain by means of injected nanoparticles that light up when exposed to X-rays (nanoscintillators) and would eliminate an invasive brain surgery currently in use.
Researchers have transformed copper nanowires into metal foams that could be used in facemasks and air filtration systems. The foams filter efficiently, decontaminate easily for reuse and are recyclable.
Scientists discovered a way to retain zinc sulfide's brilliant color and also enable its use as a catalyst; for example, to convert sunlight into usable energy.
Researchers were able to significantly reduce the thermal conductivity of lead-tellurium thermoelectrics without increasing the dislocation density. For the first time, it is demonstrated that the arrangement of the dislocations and their composition are as important as their amount.
Nonvolatile resistive memory (NVRM), also called a 'memristor', is an emerging technology that offers the possibility of in-memory computation and thus holds promise to overcome the von Neumann bottleneck. NVRM is a two-terminal device but, unlike an ordinary resistor, it exhibits hysteresis in input-output characteristics and thus can be also be used as memory. A new theory suggests that such resistive switching is an intrinsic property of a vacancy-inhabited two-dimensional materials ...
Scientists have long thought the laws of physics limited how fast you could safely recharge a battery, but new research has opened the door to creating a battery that can be recharged in just a fraction of the time.
