Scientists have demonstrated how noise in a microwave amplifier is limited by self-heating at very low temperatures. The findings can be of importance for future discoveries in many areas of science such as quantum computers and radio astronomy.
The dream of analyzing the structure of large, hard-to-crystallize proteins and other bio molecules has come one step closer to reality. In new study, researchers used a newly developed grease to suspend small crystals of lysozyme, glucose isomerase, thaumatin, and fatty acid-binding protein type-3, which they then analyzed using the revolutionary serial femtosecond crystallography method.
A team of engineers and scientists has identified a source of electronic noise that could affect the functioning of instruments operating at very low temperatures, such as devices used in radio telescopes and advanced physics experiments. The findings could have implications for the future design of transistors and other electronic components.
Researchers have demonstrated that it is possible to directly generate an electric current in a magnetic material by rotating its magnetization. The findings reveal a novel link between magnetism and electricity, and may have applications in electronics.
Researchers have found that temperature-controlled aggregation in a family of new semi-conducting polymers is the key to creating highly efficient organic solar cells that can be mass produced more cheaply.
Mike Arnold, associate professor at UW-Madison, leads a research team that focuses on the study of advanced electronic materials for photovoltaic solar energy, energy storage, and semiconductor electronics. Developing materials that can bring down the cost of PV energy is his team's passion and primary goal.
Researchers have developed a new way to grow nanowire arrays with a determined diameter, length and uniform consistency. This approach to growing nanomaterials will improve the efficiency of various devices including solar cells and fuel cells.
Scientists have succeeded in electrochemically detecting protein binding on semiconductor materials for the first time, thanks to a newly developed investigative method based on differences in electrical charge. Now the physicists are working on an optical process to detect and localise protein binding directly under a microscope, for example, a method that could launch new applications in medical research and diagnostics.
New research has demonstrated how glass can be manipulated to create a material that will allow computers to transfer information using light. This development could significantly increase computer processing speeds and power in the future.
A new study reveals the need to rethink one of science's building blocks and, with it, how some of the basic principles underlying the behavior of matter are taught in our classrooms. The researchers examined the way that a phase change, specifically the melting of a solid, occurs at a microscopic level and discovered that the transition is far more involved than earlier models had accounted for.
