Solar and wind power are key to decarbonizing Switzerland

Posted: 11 Feb 2022 07:26 AM PST

How can we reduce the carbon footprint of electricity consumption in Switzerland? The country relies on electricity imports from fossil fuel power plants, which are major emitters of greenhouse gases.

Electron conspiracy in a Japanese lattice pattern: Kagome metals baffle science

Posted: 11 Feb 2022 07:26 AM PST

Toward a new kind of superconductivity: In the past four years scientists have discovered metals whose crystal structure mimics that of a traditional Japanese woven bamboo pattern: kagome metals. The international research activity in this new direction of quantum materials has recently reached a new climax: an international team of physicists has discovered that the underlying kagome lattice structure induces the joint appearance of intricate quantum phenomena which can lead to an unprecedented type of superconductivity.

Distant galaxies and the true nature of dark matter

Posted: 11 Feb 2022 07:26 AM PST

In conflict with the current prevailing theory used to describe the universe, a new study suggests the existence of a direct interaction between the elementary particles that make up the dark matter halo and those that make up ordinary matter.

Graphene spintronics: 1D contacts improve mobility in nano-scale devices

Posted: 11 Feb 2022 07:26 AM PST

Researchers may have cleared a significant hurdle on the path to quantum computing, demonstrating step-change improvements in the spin transport characteristics of nanoscale graphene-based electronic devices.

Strong and elastic, yet degradable: protein-based bioplastics

Posted: 11 Feb 2022 07:20 AM PST

More than eight million tons of plastic end up in the oceans every year -- a serious danger for the environment and health. Biodegradable bioplastics could provide an alternative. A research team has now introduced a new method for the production of protein-based plastics that are easily processable, biodegradable, and biocompatible, as well as having favorable mechanical properties.

Novel wearable armband helps users of prosthetic hands to ‘get a grip’

Posted: 11 Feb 2022 05:06 AM PST

A new study could be a game changer for users of prosthetic hands who have long awaited advances in dexterity. Researchers examined if people could precisely control the grip forces applied to two different objects grasped simultaneously with a dexterous artificial hand. They designed a multichannel wearable soft robotic armband to convey artificial sensations of touch to the robotic hand users. Subjects were able to successfully grasp and transport two objects simultaneously with the dexterous artificial hand without breaking or dropping them, even when their vision of both objects was obstructed. The study is the first to show the feasibility of this complex simultaneous control task while integrating multiple channels of haptic/touch sensation feedback noninvasively.

A new woody composite is tough as bone and hard as aluminum, and might pave way for naturally derived plastics.

A star in the world of ceramic engineering

Posted: 10 Feb 2022 12:42 PM PST

Facing the challenging task of developing lightweight, high-strength ceramic materials, an engineer has turned to an unexpected collaborator for design inspiration: the knobby sea star from the tropical Indo-Pacific. By investigating the complex and highly ordered mineralized skeletal system of this unusual marine species, the research team discovered an unexpected combination of characteristics that may lead to developing an entirely new class of high-performance lightweight ceramic composites. 

It’s in the air – battery discovery takes up the charge

Posted: 10 Feb 2022 12:41 PM PST

Clean energy researchers have designed a molecule to boost the performance of lithium-oxygen batteries to give electric vehicles the same driving range as petrol-fueled cars. Lithium-oxygen batteries are aimed to deliver maximum energy density through breathing air to generate electricity. To date, they have been beset by challenges, including low discharge capacity, poor energy efficiency and severe parasitic reactions. This molecule can simultaneously tackle those issues.

Fueling a Hydrogen revolution

Researchers show how magnetic flux sensors can be used to monitor the operation of proton exchange membrane fuel cells that run on hydrogen. By detecting changes in current, failure states due to incorrect water levels can be identified. This work may lead to cost-effective sustainable energy generation for electric vehicles.

Cellular proteins enable tissues to sense, react to mechanical force

Posted: 10 Feb 2022 12:41 PM PST

Cellular proteins that hold cells and tissues together also perform critical functions when they experience increased tension. A new study observed that when tugged upon in a controlled manner, these proteins -- called cadherins -- communicate with growth factors to influence in vitro tumor growth in human carcinoma cells.

A new electrolyte for greener and safer batteries

Posted: 10 Feb 2022 08:41 AM PST

Researchers have developed a new material that improves the performance of solid-state sodium batteries, a less dangerous and more durable alternative to lithium.

Computing carbon storage

Posted: 10 Feb 2022 08:40 AM PST

Carbon capture and storage describes the process of injecting carbon dioxide from industrial sources into underground geological reservoirs, theoretically for thousands of years. Researchers used supercomputers to understand how carbon dioxide storage works at the level of micrometer-wide pores in rock. They found that two factors greatly impact the amount of carbon dioxide that can be stored: wettability and injection rate.
