Strange warping geometry helps to push scientific boundaries — ScienceDaily

Atomic interactions in everyday solids and liquids are so complex that some of these materials’ properties continue to elude physicists’ understanding. Solving the problems mathematically is beyond the capabilities of modern computers, so scientists at Princeton University have turned to an unusual branch of geometry instead. Researchers led by Andrew Houck, a professor of electrical engineering, have built an electronic array on a microchip that simulates particle interactions in a hyperbolic plane, a geometric surface in which space curves away…

First observation of native ferroelectric metal — ScienceDaily

In a paper released today in Science Advances, UNSW researchers describe the first observation of a native ferroelectric metal. The study represents the first example of a native metal with bistable and electrically switchable spontaneous polarization states — the hallmark of ferroelectricity. “We found coexistence of native metallicity and ferroelectricity in bulk crystalline tungsten ditelluride (WTe2) at room temperature,” explains study author Dr Pankaj Sharma. “We demonstrated that the ferroelectric state is switchable under an external electrical bias and explain…

Sliding along on water

The new in situ tribometer can measure wear and friction values directly on the slide bearing during operation. Credit: Fraunhofer IWM Machine bearings are usually lubricated with various oils. But today large quantities of these oils still end up in the environment. The Fraunhofer Institute for Mechanics of Materials IWM has developed a method which will in the future make it possible to lubricate slide bearings using water, a much more environmentally friendly approach. Bearings are usually lubricated with mineral…

Glimmers of hope? Scientists consider how unexpected awakenings in dementia patients might shed new light on the disease — ScienceDaily

It happens unexpectedly: a person long thought lost to the ravages of dementia, unable to recall the events of their lives or even recognize those closest to them, will suddenly wake up and exhibit surprisingly normal behavior, only to pass away shortly thereafter. This phenomenon, which experts refer to as terminal or paradoxical lucidity, has been reported since antiquity, yet there have been very few scientific studies of it. That may be about to change. In an article published in…

Discovery leads to promising new materials for converting waste heat to power — ScienceDaily

The promise of thermoelectric materials as a source of clean energy has driven the search for materials that can efficiently produce substantial amounts of power from waste heat. Researchers reported a major step forward Friday, publishing in Science Advances the discovery of a new explanation for asymmetrical thermoelectric performance, the phenomenon that occurs when a material that is highly efficient in a form which carries a positive charge is far less efficient in the form which carries a negative charge,…

A device emerges from the fusion of IGZO and ferroelectric-HfO2

(a) Schematic of ferroelectric-HfO2 based FeFET with 3D vertical stack structure for high memory capacity. Poly-silicon is typically used as a channel material. In this work, we propose to use IGZO as a channel material. (b) Schematic illustration of current challenges of poly-silicon channel and possible solution by IGZO channel. Poly-silicon has low mobility in nanometer thickness region and forms low-k interfacial layer which causes voltage loss and charge trapping. As a part of JST PRESTO program, Associate professor Masaharu…

Drones for early detection of forest fires

Credit: CC0 Public Domain The UC3M’s researchers coordinating the scientific part of the project, Fernando García y Abdulla al-Kaff, from the Department of Systems Engineering and Automation, have developed the complete automatic flight system, as well as the interface with which the emergency service can access information about what is occurring in real time. “The drone we have developed for the project has a thermal camera, an optical camera, and four sensors which allow us to identify the temperature of…

Wind tunnel tests could help kites become a clean energy high-flier

Credit: CC0 Public Domain The use of kites to capture wind energy and turn it into cost-effective ‘green’ electricity could be coming within reach, with EPSRC-funded research at Imperial College London playing an important role in making it possible. Linked to a wider Innovate UK-funded project, a team at Imperial’s Department of Aeronautics has put a kite-energy device through its paces using a wind tunnel that is part of the EPSRC-supported National Wind Tunnel Facility (NWTF). The data produced has…

Clarifying the economic value of adjusting power consumption

Credit: CC0 Public Domain Since the output of renewable energy such as photovoltaic generation tends to fluctuate, the power system can be viewed as a large-scale complex system with uncertainty. To stabilize the balance of supply and demand of electricity, we need an energy management system to control this. In recent years, energy management systems have been actively researched against the background of the liberalization of power and the spread of smart meters that visualize the power consumption. Koichi Kobayashi,…

Researchers create soft, flexible materials with enhanced properties — ScienceDaily

A team of polymer chemists and engineers from Carnegie Mellon University have developed a new methodology that can be used to create a class of stretchable polymer composites with enhanced electrical and thermal properties. These materials are promising candidates for use in soft robotics, self-healing electronics and medical devices. The results are published in the May 20 issue of Nature Nanotechnology. In the study, the researchers combined their expertise in foundational science and engineering to devise a method that uniformly…
