A new Approach to look inside of Molecules
In 1921, Albert Einstein received the Nobel Prize in physics for the discovery that light is quantized, interacting with matter as a stream of particles called photons. Since these early days of quantum mechanics, it is known that photons also possess momentum. The photon’s ability to transfer ...
Research team discovered a remarkable echo effect - it offers exciting new possibilities for working with quantum information
Small particles can have an angular momentum that points in a certain direction - the spin. This spin can be manipulated by a magnetic field. This principle, for example, is the basic idea behind magnetic resonance imaging as used in hospitals. An international research team has now discovered a ...
Electrochemical reactions, which will play an important role in the future of energy supply, can now be explained in detail
Electrochemistry is playing an increasingly important role: Whether it is fuel cells, electrolysis or chemical energy storage, chemical reactions controlled by electric current are used. The decisive factor in all these applications is that the reactions are as fast and efficient as possible. An ...
For the first time, researchers have managed to create and identify antiferromagnetic skyrmions with a unique property
Nanoscale vortices known as skyrmions can be created in many magnetic materials. For the first time, researchers at PSI have managed to create and identify antiferromagnetic skyrmions with a unique property: critical elements inside them are arranged in opposing directions. Scientists have ...
Compact and energy-efficient sensor for mobile devices, informs in real time about the fine dust content in the air and warns in case of elevated values
It is slightly smaller than two one-cent coins stacked on top of each other, is particularly energy-efficient due to its size, requires no maintenance and can be integrated in mobile devices. It is the smallest particle sensor in the world. With this 12 x 9 x 3 millimetre innovation, smartphones, ...
Get zeolite research out of the dead end
Researchers at the Paul Scherrer Institute PSI and from ETH Zurich want to make so-called zeolites more efficient. Today, these compounds are already indispensable additives in the chemical industry and have been used as catalysts in oil refineries since the 1960s. Now, in the journal Nature ...
New approaches to promote the use of nuclear magnetic resonance spectroscopy for analysis in chemistry, biology, and medicine
The diverse work of Mainz-based physicists in the field of nuclear magnetic resonance is being boosted by a new highly application-oriented approach: In October 2020, Dr. Danila Barskiy will join Johannes Gutenberg University Mainz (JGU) to set up a group focusing on nuclear magnetic resonance ...
Promising way to to transform ethylene production into a greener industry
A research team from Caltech and the UCLA Samueli School of Engineering has demonstrated a promising way to efficiently convert carbon dioxide into ethylene -- an important chemical used to produce plastics, solvents, cosmetics and other important products globally. The scientists developed ...
Pointed tips on aluminum 'octopods' increase catalytic reactivity
Points matter when designing nanoparticles that drive important chemical reactions using the power of light. Researchers at Rice University's Laboratory for Nanophotonics (LANP) have long known that a nanoparticle's shape affects how it interacts with light, and their latest study shows how shape ...
An understanding of microscopic processes in perovskite solar cells can lead to increased efficiency
When the sun rises, a complex dance begins in perovskite solar cells - a type of solar cell that can supplement or replace existing silicon solar cells in the future: Electrons are supplied with energy by light and move. Where electrons move, they leave holes. At the same time, ions move around ...
