Electrical steel: Strong magnetic fields due to sharp tools
Electrical steel: Strong magnetic fields due to sharp tools
Research news In an electric drive, magnetic fields have to be created in order to transform electric energy into kinetic energy. The magnetic properties of the motor's main components, referred to as electrical steel sheets, are the decisive factor in the efficiency of the electric motor. Scientists at the Technical University of Munich (TUM) have investigated the way these steel sheets are processed and have concluded that using blunt cutting tools deteriorates the magnetic properties of the steel sheets significantly.

Zero gravity graphene promises success in space
In a series of experiments conducted last month, Cambridge researchers experienced weightlessness testing graphene's application in space. This is the first time that graphene has been tested in space-like applications. Andrea Ferrari Working as part of a collaboration between the Graphene Flagship and the European Space Agency, researchers from the Cambridge Graphene Centre tested graphene in microgravity conditions for the first time while aboard a parabolic flight - often referred to as the 'vomit comet'.

X-Ray Experiments Suggest High Tunability of 2-D Material
X-Ray Experiments Suggest High Tunability of 2-D Material
Scientists at Berkeley Lab use a new platform, called MAESTRO, to see microscale details in monolayer material's electronic structure To see what is driving the exotic behavior in some atomically thin - or 2-D - materials, and find out what happens when they are stacked like Lego bricks in different combinations with other ultrathin materials, scientists want to observe their properties at the smallest possible scales.

Neighboring glaciers may cause each other to melt faster
Two of the most rapidly changing glaciers in Antarctica, which are leading contributors to sea-level rise, may behave as an interacting system rather than separate entities, according to a new analysis of radar data. A new study shows that a large and potentially unstable Antarctic glacier may be melting farther inland than previously thought and that this melting could affect the stability of another large glacier nearby - an important finding for understanding and projecting ice sheet contributions to sea-level rise.

Using electricity to switch magnetism
Using electricity to switch magnetism
At TU Wien, a major step has been taken towards linking electrical and magnetic material properties, which is crucial for possible applications in electronics. It's not exactly a new revelation that electricity and magnetism are closely linked. And yet, magnetic and electrical effects have been studied separately for some time now within the field of materials science.

Turning heat into electricity
Turning heat into electricity
What if you could run your air conditioner not on conventional electricity, but on the sun's heat during a warm summer's day? With advancements in thermoelectric technology, this sustainable solution might one day become a reality. Thermoelectric devices are made from materials that can convert a temperature difference into electricity, without requiring any moving parts - a quality that makes thermoelectrics a potentially appealing source of electricity.

X-Rays Reveal 'Handedness' in Swirling Electric Vortices
X-Rays Reveal ’Handedness’ in Swirling Electric Vortices
Scientists at Berkeley Lab study exotic material's properties, which could make possible a new form of data storage Scientists used spiraling X-rays at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) to observe, for the first time, a property that gives handedness to swirling electric patterns - dubbed polar vortices - in a synthetically layered material.

Robots aid better understanding of phytoplankton blooms
Robots aid better understanding of phytoplankton blooms
Phytoplankton blooms are one of the most important factors contributing to the efficiency of the carbon pump in the North Atlantic Ocean. To better understand this phenomenon, the ERC remOcean 1 project, led by researchers at the Laboratoire d'Océanographie de Villefranche (CNRS/UPMC), has developed a new class of robots: biogeochemical profiling floats, the first robots able to collect data in the ocean throughout the year.

Smart buildings that can manage our electricity needs
Smart buildings that can manage our electricity needs
Researchers at EPFL have developed a system that can be installed in a building to collect data on people's energy usage. The aim is then to send this data directly to a smart electric grid that will allocate resources optimally. A smart grid that decides how best to distribute energy based on availability, cost and customers' needs - that's the energy concept being developed by researchers in the School of Engineering's Electronics Laboratory.

Sensor-enhanced surgical robot enables highly precise and safe spinal operations
Sensor-enhanced surgical robot enables highly precise and safe spinal operations
Researchers from the University of Bern, Inselspital, Bern University Hospital and the Swiss Center for Electronics and Microtechnology develop a high-precision, sensor-based surgical robot for spinal operations together with industry partners. Their project is being funded with two million Swiss francs, sponsored by the "BRIDGE" programme of the Swiss National Science Foundation and the Commission for Technology and Innovation.

New depth sensors could be sensitive enough for self-driving cars
For the past 10 years, the Camera Culture group at MIT's Media Lab has been developing innovative imaging systems - from a camera that can see around corners to one that can read text in closed books - by using "time of flight," an approach that gauges distance by measuring the time it takes light projected into a scene to bounce back to a sensor.

Memristors power quick-learning neural network
ANN ARBOR-A new type of neural network made with memristors can dramatically improve the efficiency of teaching machines to think like humans. The network, called a reservoir computing system, could predict words before they are said during conversation, and help predict future outcomes based on the present.

A particle like slow light
A particle like slow light
A remarkable discovery was made at TU Wien recently, when particles known as 'Weyl fermions' were discovered in materials with strong interaction between electrons. Just like light particles, they have no mass but nonetheless they move extremely slowly. There was great excitement back in 2015, when it was first possible to measure these 'Weyl fermions' - outlandish, massless particles that had been predicted almost 90 years earlier by German mathematician, physician and philosopher, Hermann Weyl.

First experiment at SwissFEL carried out successfully
The years of careful planning and construction have paid off: At the newest large-scale research facility of the Paul Scherrer Institute PSI - the free-electron X-ray laser SwissFEL - the first experiment has been carried out successfully. With that, two goals have been achieved: First, a new scientific result is already expected.

The quantum waltz of electrons hints at the next generation of chips
EPFL researchers have successfully measured some of the quantum properties of electrons in two-dimensional semiconductors. This work in the field of spintronics could one day lead to chips that are not only smaller but that also generate less heat. A group of spintronics researchers at EPFL is using new materials to reveal more of the many capabilities of electrons.

Warmed up and raring to go
Warmed up and raring to go
During cold-start, a car engine emits far more particulate matter and other pollutants than during warm conditions. This is because a cold catalytic converter is much less efficient at low exhaust gas temperatures. So what's the answer? Preheat the cat with microwaves. Empa scientists have developed the first microwave converter heating for passenger car applications.

Squeezing light into a tiny channel brings optical computing a step closer
Squeezing light into a tiny channel brings optical computing a step closer
By forcing light to go through a smaller gap than ever before, researchers have paved the way for computers based on light instead of electronics. Light is desirable for use in computing because it can carry a higher density of information and is much faster and more efficient than conventional electronics.

GP online consultations: not the panacea policy makers are hoping for
Online GP consultation systems may not be the silver bullet for reducing GP workload and patient waiting times that government policymakers are hoping for, NIHR-funded research from the University of Bristol has found. These systems offer the potential to revolutionise use of primary care, but only with careful implementation and effective marketing, the researchers concluded.
