Engineers have developed a powerful new tool that monitors the electrical activity inside heart cells, using tiny 'pop-up' sensors that poke into cells without damaging them.
Scientists develop concept for feedback-controlled optical tweezers. These tweezers made of highly focused laser light can grab cell clusters in a controlled manner and rotate them in any direction. This will allow objects such as miniature tumors to be studied more specifically under the microscope.
Researchers report stable and high oxide-ion conductors based on a new hexagonal perovskite-related oxide. These high-performance oxide-ion conductors could pave the way for the development of solid electrolytes for next-generation batteries and clean energy devices such as solid oxide fuel cells.
Which factors determine how fast a quantum computer can perform its calculations? Physicists have devised an elegant experiment to answer this question.
A large, unconventional anomalous Hall resistance in a new magnetic semiconductor in the absence of large-scale magnetic ordering has been demonstrated by materials scientists, validating a recent theoretical prediction. Their findings provide new insights into the anomalous Hall effect, a quantum phenomenon that has previously been associated with long-range magnetic order.
Researchers have developed a technique to improve the flexibility of ultra-thin electronics, such as those used in bendable devices or clothing. The study details the use of water vapor plasma to directly bond gold electrodes fixed onto separate ultra-thin polymer films, without needing adhesives or high temperatures.
Researchers fabricated a 14 cm tall Christmas tree with a thickness of one atom and showed how terahertz measurements can be used to ensure the quality of graphene.
