Moments of silence point the way towards better superconductors

Temporal patterns could show us how to reduce noise in superconductor devices

23-Dec-2021

High-precision measurements have provided important clues about processes that impair the efficiency of superconductors. Future work building on this research could offer improvements in a range of superconductor devices, such quantum computers and sensitive particle detectors. Superconductivity ...

Creating solar cells and glass from wood – or a billion tons of biowaste

Researchers map out how biomass from plants could replace unrenewable resources in optical applications

08-Nov-2021

A digital, urbanised world consumes huge amounts of raw materials that could hardly be called environmentally friendly. One promising solution may be found in renewable raw materials, according to research published in Advanced Materials. In their paper, the international research group has taken ...

Non-toxic technology extracts more gold from ore

New chloride-based process recovers 84% of gold compared to the 64% recovered with traditional methods

06-Oct-2021

Gold is one of the world’s most popular metals. Malleable,conductiveand non-corrosive, it’s used in jewelry, electronics, and even space exploration. But traditional gold production typically involves a famous toxin, cyanide, which has been banned for industrial use in several countries. The ...

New high-speed method for spectroscopic measurements

23-Jun-2021

Researchers at Tampere University and their collaborators have shown how spectroscopic measurements can be made much faster. By correlating polarization to the colour of a pulsed laser, the team can track changes in the spectrum of the light by simple and extremely fast polarization measurements. ...

Battery parts can be recycled without crushing or melting

New recycling method replenishes lithium in electrodes while keeping existing structure intact - and performance is nearly as good as new ones

05-May-2021

The proliferation of electric cars, smartphones, and portable devices is leading to an estimated 25 percent increase globally in the manufacturing of rechargeable batteries each year. Many raw materials used in the batteries, such as cobalt, may soon be in short supply. The European Commission is ...

Choosing the right partner: Synthesis of a rare metal complex of nitrous oxide opens new vistas for the degradation of a potent greenhouse gas

25-Feb-2021

Like its chemical relative carbon dioxide (CO2), nitrous oxide (N2O) is an important greenhouse gas and the dominant ozone-depleting substance emitted in the 21st Century. Consequently, strategies for limiting its emissions and its catalytic decomposition with metals are being developed. A recent ...
