Kiel University and Trinity College Dublin receive €2.5 million EU funding to develop particularly reliable and sustainable transformers. When power fails in data centres, the damage is often great: not only is the operation of companies or institutions interrupted, but important data can also be lost. In addition, the facilities are known for their high energy consumption. The goal of the research project “Super-HEART” is a power supply that can reliably use several sustainable energy sources such as hydrogen and…
Research consortium sets standards in the field of open source hardware. The HEP research project has presented an open, flexible design for a security chip. The project “Hardening the value chain through open source, trusted EDA tools and processors (HEP)”, funded by the German Federal Ministry of Education and Research (BMBF), uses open source, free components and tools to manufacture a chip at the IHP fab – the Leibniz-Institute for High Performance Microelectronics. The easy accessibility of the used process…
Integrated THz emitter for precise rotating target detection. Researchers integrate terahertz vortex beam emission to advance radar target detection technology. You may not realize it, but the Doppler effect is everywhere in our lives, from tracking the speed of cars with radar to locating satellites in the sky. It’s all about how waves change their frequency when a source (like a radar signal) and a detector are in motion relative to each other. However, traditional radar systems hit a roadblock…
… captures the body’s immune response to COVID-19 infection. Total-body PET scan uses less radiation and gives better imaging of immune T cell distribution. A team of UC Davis scientists used dynamic total-body positron emission tomography (PET) to provide the first imaging of the human body’s immune response to COVID-19 infection in recovering patients. Their work, published in Science Advances, could lead to a better understanding of how the body’s immune system responds to viral infections and develops long-term protection….
Narrow jet stream near Jupiter’s equator has winds traveling 320 miles per hour. NASA’s James Webb Space Telescope has discovered a new, never-before-seen feature in Jupiter’s atmosphere. The high-speed jet stream, which spans more than 3,000 miles (4,800 kilometers) wide, sits over Jupiter’s equator above the main cloud decks. The discovery of this jet is giving insights into how the layers of Jupiter’s famously turbulent atmosphere interact with each other, and how Webb is uniquely capable of tracking those features….
In a finding that helps elucidate how molten salts in advanced nuclear reactors might behave, scientists have shown how electrons interacting with the ions of the molten salt can form three states with different properties. Understanding these states can help predict the impact of radiation on the performance of salt-fueled reactors. The researchers, from the Department of Energy’s Oak Ridge National Laboratory and the University of Iowa, computationally simulated the introduction of an excess electron into molten zinc chloride salt…
The ‘wonder material’ graphene is well-known for its high electrical conductivity, mechanical strength, and flexibility. Stacking two layers of graphene with atomic layer thickness produces bilayer graphene, which possesses excellent electrical, mechanical, and optical properties. As such, bilayer graphene has attracted significant attention and is being utilized in a host of next-generation devices, including quantum computers. But complicating their application in quantum computing comes in the form of gaining accurate measurements of the quantum bit states. Most research has primarily…
Bio-machine hybrid robots (BHRs) represent a new generation of micro-aerial vehicles that be controlled by building an interface between biological and artificial systems. In contrast to conventional bionic robots, they are free of complex mechanical structures, and due to the direct adoption of the animal body, they have superior moving characteristics and lower energy demand. Thus, the BHRs can be applied in many important scenarios, such as urban and wilderness rescue operations, environmental monitoring and hazardous area surveys. To accomplish…
Team of researchers urges further study and evaluation of standards for medical use. Cannabis use, even for medical purposes, could make some people sick due to harmful fungi that contaminate the plants. That is the finding of a recently published peer-reviewed journal article, whose authors recommend further study and consideration of changes to regulations to protect consumers, especially those who are immunocompromised. They examined data, previous studies, and U.S. and international regulations related to the cannabis and hemp industry. The…
Quantum sensors make microscale NMR spectroscopy possible. The development of tumors begins with miniscule changes within the body’s cells; ion diffusion at the smallest scales is decisive in the performance of batteries. Until now the resolution of conventional imaging methods has not been high enough to represent these processes in detail. A research team led by the Technical University of Munich (TUM) has developed diamond quantum sensors which can be used to improve resolution in magnetic imaging. Robin Allert (left)…
World premiere: New system that is gentler on patients receives the pulse beat. On the road to gentler mechanical cardiac support, the cardiac surgery clinics of Hannover Medical School (MHH) and the Freeman Hospital in Newcastle upon Tyne (UK) have briefly implanted a novel, groundbreaking circulatory support system in the first five people with advanced heart failure in the world. The heart support technology, called reBEAT, is a new development by the Munich-based start-up company AdjuCor. It consists of an…
Jena researchers develop new method for manufacturing tailor-made semiconductor thin films. Organic semiconductor materials are promising key technologies for the development of state-of-the-art optoelectronic components and are used in photovoltaics as well as in sensor technology and microelectronics. In order to produce thin organic semiconductor films automatically and with well-defined properties, researchers – led by Leibniz IPHT in Jena, Germany – have developed a new technological approach for depositing thin films with high molecular precision. The method for manufacturing thin…
Whenever light interacts with matter, light appears to slow down. This is not a new observation and standard wave mechanics can describe most of these daily phenomena. For example, when light is incident on an interface, the standard wave equation is satisfied on both sides. To analytically solve such a problem, one would first find what the wave looks like at either side of the interface, and then employ electromagnetic boundary conditions to link the two sides together. This is…
Researchers have discovered a way to make ceramics tougher and more resistant to cracking. By building these materials using a blend of metal atoms possessing more electrons in their outer shell, a team led by engineers at the University of California San Diego has unlocked the potential to enable ceramics to handle higher levels of force and stress than before. Ceramics offer many advantages due to their remarkable properties, including their ability to withstand extremely high temperatures, resist corrosion and…
A replacement for cobalt in batteries avoids its environmental and social impacts. High-capacity and reliable rechargeable batteries are a critical component of many devices and even modes of transport. They play a key role in the shift to a greener world. A wide variety of elements are used in their production, including cobalt, the production of which contributes to some environmental, economic, and social issues. For the first time, a team including researchers from the University of Tokyo presents a…
The seemingly physics-defying properties of quasiparticles could be harnessed for applications ranging from non-destructive imaging to computer-chip manufacturing. An international team of scientists is rethinking the basic principles of radiation physics with the aim of creating super-bright light sources.
