The first comprehensive analysis of e-waste in Canada found electronic waste has tripled and is steadily growing New research finds that Canada's electrical and electronic waste (e-waste) has more than tripled in the last two decades, the equivalent of filling the CN tower 110 times and generating close to a million tons in 2020 alone.

The Technische Universität Ilmenau, together with research partners, has developed a microphone inspired by biology that picks up sound similar to the human ear. The microphone could help improve speech recognition for controlling a variety of digital applications. In the future, the new process could even make overall acoustic systems consisting of a microphone and speech recognition more efficient, so that they consume less energy.

May 3, 2023 New material converts vibrations into electricity  In a world hungry for clean energy, engineers have created a new material that converts the simple mechanical vibrations all around us into electricity to power sensors in everything from pacemakers to spacecraft. The first of its kind and the product of a decade of work by researchers at the University of Waterloo and the University of Toronto, the novel generating system is compact, reliable, low-cost and very, very green.

This doesn't happen often: For his final project, an electronics apprentice at ETH Zurich produced a test device that will save physicists a lot of time in developing a novel microscope. His work has been published in a scientific journal. Integrated into the research group Apprentices also have to prepare a detailed schedule for their IPA.

The device, which uses electricity to boost hormone production in the stomach, could help to ease nausea and counteract appetite loss. Hormones released by the stomach, such as ghrelin, play a key role in stimulating appetite. These hormones are produced by endocrine cells that are part of the enteric nervous system, which controls hunger, nausea, and feelings of fullness.

Thanks to a breakthrough in the field of magnonics, researchers have sent and stored data using charge-free magnetic waves, rather than traditional electron flows. The discovery could solve the dilemma of energy-hungry computing technology in the age of big data. Like electronics or photonics, magnonics is an engineering subfield that aims to advance information technologies when it comes to speed, device architecture, and energy consumption.

Tiny structures made of gold can be specifically manipulated by ion bombardment at TU Wien (Vienna) - surprisingly, the decisive factor is not the force of the impact. Normally, we have to make a choice in physics: Either we deal with big things - such as a metal plate and its material properties, or with tiny things - such as individual atoms.

An international team led by the University of Geneva has developed a quantum material in which the fabric of space inhabited by electrons can be curved on-demand. Artistic view. Curvature of the space fabric due to the superposition of spin and orbital states at the interface between lanthanum aluminate (LaAlO3) and strontium titanate (SrTiO3).

Nearly a decade ago, researchers heralded the discovery of a new wonder class of ultrathin materials with special optical and electrical properties that made it a potential rival for graphene, a form of carbon discovered in 2004 whose own special properties interest both scientists and engineers. Now, Caltech engineers have shown that one of these wonder materials, tungsten diselenide, is not just a rival to graphene but also a complement to it.

Researchers have come up with a new approach to electronics that involves engineering metastructures at the sub-wavelength scale. It could launch the next generation of ultra-fast devices for exchanging massive amounts of data, with applications in 6G communications and beyond. Until now, the ability to make electronic devices faster has come down to a simple principle: scaling down transistors and other components.

The idea of journeying inside the human body to solve medical problems has been around at least since a hokey sci-fi film popularized the concept in the 1960s, but this approach to medicine has never become real because shrinking rays, sadly, do not exist. However, researchers have developed proxies for human doctors that are small enough travel through the human body and help diagnose ailments.

The sensor sends out its location as it moves through the GI tract, revealing where slowdowns in digestion may occur. Close Engineers at MIT and Caltech have demonstrated an ingestible sensor whose location can be monitored as it moves through the digestive tract, an advance that could help doctors more easily diagnose gastrointestinal motility disorders such as constipation, gastroesophageal reflux disease, and gastroparesis.

"Squeezing" noise over a broad frequency bandwidth in a quantum system could lead to faster and more accurate quantum measurements. Close A certain amount of noise is inherent in any quantum system. For instance, when researchers want to read information from a quantum computer , which harnesses quantum mechanical phenomena to solve certain problems too complex for classical computers, the same quantum mechanics also imparts a minimum level of unavoidable error that limits the accuracy of the measurements.

A quick electric pulse completely flips the material's electronic properties, opening a route to ultrafast, brain-inspired, superconducting electronics. Close With some careful twisting and stacking, MIT physicists have revealed a new and exotic property in "magic-angle" graphene: superconductivity that can be turned on and off with an electric pulse, much like a light switch.

Countries and corporations around the world are researching a completely new type of computer - quantum computers. But the road to usability is arduous. Researchers at Johannes Kepler University Linz have succeeded in making progress in the storage of quantum information as part of an international collaboration.

University of Sheffield researchers have developed 3D-printed radio antennas that could be used to bring the fastest mobile phone networks to people living in remote areas for the first time 3D-printed millimetre wave aerials are much quicker and cheaper to produce than those currently used by the telecommunications industry, but have the same level of performance Development could help to drive innovation, speed up the production of new prototy

Within the framework of the Würzburg-Dresden Cluster of Excellence ct.qmat, excitons were generated in a topological insulator for the first time. A breakthrough in quantum research, based on material design from Würzburg. An international team of scientists collaborating within the Würzburg-Dresden Cluster of Excellence ct.qmat has achieved a breakthrough in quantum research - the first detection of excitons (electrically neutral quasiparticles) in a topological insulator.

Scientists at EPFL have overcome the scaling challenges of quantum optomechanical systems and realized the first superconducting circuit optomechanical graphene lattice. The precise control of micro-mechanical oscillators is fundamental to many contemporary technologies, from sensing and timing to radiofrequency filters in smartphones.

Antiferromagnets are suitable for transporting spin waves over long distances Smaller, faster, more powerful: The demands on microelectronic devices are high and are constantly increasing. However, if chips, processors and the like are based on electricity, there are limits to miniaturization. Physicists are therefore working on alternative ways of transporting information, such as about spin waves, also called magnons, for example.

Physicists at the University of Basel have experimentally demonstrated for the first time that there is a negative correlation between the two spins of an entangled pair of electrons from a superconductor. For their study, the researchers used spin filters made of nanomagnets and quantum dots, as they report in the scientific journal Nature.
