Sensors and orthoses are possible fields of application

23-Sep-2022

Until now, it has not been possible to additively manufacture sensors and other electronic devices in a single operation. However, a research team from the Fraunhofer Institute for Manufacturing Engineering and Automation IPA has now succeeded in doing just that. The key to this achievement? ...

Light accelerates conductivity in nature’s ‘electric grid’

“It is a completely different form of photosynthesis”

09-Sep-2022

The natural world possesses its own intrinsic electrical grid composed of a global web of tiny bacteria-generated nanowires in the soil and oceans that “breathe” by exhaling excess electrons. In a new study, Yale University researchers discovered that light is a surprising ally in fostering this ...

New magnesium superionic conductor towards lithium-free solid-state batteries

Scientists demonstrate for the first time a metal–organic framework-based magnesium ion conductor showing superionic conductivity even at room temperature

11-Aug-2022

The development of highly efficient energy storage devices that can store renewable energy is crucial to a sustainable future. In today’s world, solid-state rechargeable lithium ion (Li+) batteries are the state of the art. But lithium is a rare earth metal, and society’s dependence on the ...

New Measurement Method in Molecular Electronics

Method for measuring the conductivity of individual pharmaceutical and biological molecules

27-May-2022

Controlling electrical signals using single molecules enables the miniaturization of transistors in integrated circuits down to the atomic level. This research area of molecular electronics not only paves the way for the next generation of ultra-powerful computers, but also for entirely new ...

How glass learns to illuminate itself and create heat

Among other things, this can be used to produce electrically conductive and self-heating glass microreactors for the chemical and pharmaceutical industries

31-Mar-2022

Glass objects which glow in the dark, glass containers that heat up and cool down, or glass control knobs and switches that eliminate viruses and bacteria by themselves – all this seems to completely contradict our everyday experience of what glass can do. And yet, it is now within reach. To ...

How do good metals go bad?

New measurements have solved a mystery in solid state physics: How is it that certain metals do not seem to adhere to the valid rules?

16-Mar-2021

We all have a clear picture in mind when we think of metals: We think of solid, unbreakable objects that conduct electricity and exhibit a typical metallic sheen. The behaviour of classical metals, for example their electrical conductivity, can be explained with well-known, well-tested physical ...

The light side of the Force: Creating a metal with laser light

The conversion to a metal only takes 20 femtoseconds

16-Feb-2021

A group of researchers from the Fritz Haber Institute of the Max Planck Society and the Humboldt-Universität zu Berlin have found out that semiconductors can be converted to metals and back more easily and more quickly than previously thought. This discovery may increase the processing speed and ...

Oxide tuning by ion transfer

Researchers discover new formula for changing the electronic and magnetic properties of oxide interfaces

21-Dec-2020

Most materials are either magnetic, or they are not. However, scientists at Forschungszentrum Jülich have now discovered a new mechanism that allows for tailoring the electronic and magnetic properties of a material in a targeted and reversible manner. The effect depends on the transfer of ions ...

Bipolar doping

New approach facilitates the control of reversible conductivity in semiconductors

17-Nov-2020

The semiconductor gallium oxide is thought to be a promising candidate for potential use in power electronics. So far, however, a number of obstacles have stood in its path, especially how to specifically influence the material’s electrical conductivity. In a study published in the journal ...

When metal flows like liquid glass: a technology for producing superplastic wire is proposed

New ways to modify the structure of aluminium alloys for improving their performance

08-Jul-2020

Currently, low-alloy aluminium is widely used in electrical engineering and machine building. At the same time, it should be noted that modern electrical engineering places very high and in some cases mutually exclusive requirements to aluminium alloys. For example, conductive aluminium alloys ...
