Quantum dots are manmade nanoparticles of semiconducting material comprising only a few thousand atoms. Because of the small number of atoms, a quantum dot's properties lie between those of single atoms or molecules and bulk ...
Tiny fluorescent semiconductor dots, called quantum dots, are useful in a variety of health and electronic technologies but are made of toxic, expensive metals. Nontoxic and economic carbon-based dots are easy to produce, ...
A new path toward sending and receiving information with single photons of light has been discovered by an international team of researchers led by the University of Michigan.
The quantum computer race is in full swing. Germany has long been one of the world leaders in basic research. An alliance between Forschungszentrum Jülich and the semiconductor manufacturer Infinion, together with institutes ...
A polymer that is custom designed to produce light that penetrates murky environments has shown promise in bioimaging trials, where it can detect nano-sized particles underneath the surface of realistic tissue models.
Researchers have found a way to use light and a single electron to communicate with a cloud of quantum bits and sense their behavior, making it possible to detect a single quantum bit in a dense cloud.
The modern world is powered by electrical circuitry on a "chip"—the semiconductor chip underpinning computers, cell phones, the internet, and other applications. In the year 2025, humans are expected to be creating 175 ...
Oxygen is essential for human life, but within the body, certain biological environmental conditions can transform oxygen into aggressively reactive molecules called reactive oxygen species (ROS), which can damage DNA, RNA, ...
Consumers of purchased foods have no way of ascertaining the quality and safety of the food that existing distribution systems deliver to their plates. Unfortunately, inappropriate refrigeration can sometimes lead to food ...
Producing clean energy and reducing the power consumption of illumination and personal devices are key challenges to reduce the impact of modern civilization on the environment. As a result, the surging demand for solar cells ...
