Transistors are the basis for microchips and the whole electronic industry. The invention of transistors, by Bardeen and Brattain in 1947, awarded with a Nobel prize, is regarded as one of the most important discoveries of ...
A Bloch point is a singular point around which the field vectors are oriented in nearly all directions. In magnetics, it is the natural link between classical and quantum magnetism, and it has not been directly observed. ...
Researchers have developed a new technique to view living mammalian cells. The team used a powerful laser, called a soft X-ray free electron laser, to emit ultrafast pulses of illumination at the speed of femtoseconds, or ...
Lighting a gas grill, getting an ultrasound, using an ultrasonic toothbrush—these actions involve the use of materials that can translate an electric voltage into a change in shape and vice versa.
It is known that malfunctions of the proteins FLVCR1 and FLVCR2 lead to rare hereditary diseases in humans that cause motor, sensory and neurological disorders. However, the biochemical mechanisms behind this and the physiological ...
The scorching surface of Venus, where temperatures can climb to 480°C (hot enough to melt lead), is an inhospitable place for humans and machines alike. One reason scientists have not yet been able to send a rover to the ...
Plastic pollution presents a global challenge that must be solved. In particular, packaging accounts for 30–50% of the total plastic consumption. While paper packaging is eco-friendly, it lacks crucial functionalities like ...
For the first time, scientists have observed plasma waves from a solar flare focused by a coronal hole, akin to the focusing of sound waves responsible for the Rotunda effect in architecture or the focusing of light by a ...
A low-cost, tin-based catalyst can selectively convert carbon dioxide to three widely produced chemicals—ethanol, acetic acid and formic acid.
In a study published in Nature Materials, scientists from the University of California, Irvine describe a new method to make very thin crystals of the element bismuth—a process that may aid the manufacturing of cheap flexible ...
