Parts of the moon may provide stable temperatures for humans, researchers find

Posted by in categories: computing, space

Unlike the moon’s surface, which heats up to 260 degrees Fahrenheit (127 degrees Celsius) during the day and drops to minus 280 degrees Fahrenheit (minus 173 degrees Celsius) at night, these lunar pits in the Mare Tranquillitatis region have a human-friendly, stable temperature.

(Mare Tranquillitatis, commonly known as the Sea of Tranquility, is where Apollo 11, the first mission to put humans on the moon, landed due to its smooth and relatively flat terrain.)

The data comes from an analysis of images taken by NASA’s Lunar Reconnaissance Orbiter spacecraft and computer modeling.

2D materials with diversely behaving layers in a single bulk material

Posted by in categories: computing, particle physics

Scientists from The University of Manchester have developed a novel yet simple method for producing vertical stacks of alternating superconductor and insulator layers of tantalum disulphide (TaS 2). The findings, from a team led by Professor Rahul Nair, could speed up the process of manufacturing such devices – so-called van der Waals heterostructures – with application in high-mobility transistors, photovoltaics and optoelectronics.

Van der Waals heterostructures are much sought after since they display many unique and useful properties not found in naturally occurring materials. In most cases, they are prepared by manually stacking one layer over the other in a time-consuming and labour-intensive process.

An engineering breakthrough using DNA could unlock the quantum computing revolution

Posted by in categories: bioengineering, biotech/medical, chemistry, computing, quantum physics

Scientists from the University of Virginia School of Medicine and collaborators used the building blocks of life to potentially revolutionize electronics.

The scientists utilized DNA to guide a chemical reaction that would overcome the barrier to Little’s superconductor, which was once thought to be “insurmountable”, a press statement reveals.

New path for next-generation polymer-based battery design

Posted by in categories: computing, materials

A breakthrough from Deakin University researchers could help address a major obstacle in the development of environmentally-friendly, cost effective, polymer-based batteries.

The team from Deakin’s Institute for Frontier Materials (IFM) used modeling and simulations to design a new type of solid-state polymer electrolyte, showing its potential use in various types of polymer-based solid-state batteries, particularly sodium and potassium batteries.

Polymer-based batteries are able to support high-energy density metals in an all solid-state batteries. They use polymer as the ion conductor rather than flammable organic liquid solvents in current lithium-ion batteries. Therefore, a polymer-based solid-state battery offers an energy storage option that is greener, safer and providing a higher capacity, meaning more energy.

Researchers engineer biofilm capable of producing long-term, continuous electricity from your sweat

Posted by in categories: biotech/medical, computing, engineering, wearables

Researchers have reported the discovery of an exoplanet orbiting Ross 508 near the inner edge of its habitable zone.


Researchers at the University of Massachusetts Amherst recently announced that they have figured out how to engineer a biofilm that harvests the energy in evaporation and converts it to electricity. This biofilm, which was announced in Nature Communications, has the potential to revolutionize the world of wearable electronics, powering everything from personal medical sensors to personal electronics.

“This is a very exciting technology,” says Xiaomeng Liu, graduate student in electrical and computer engineering in UMass Amherst’s College of Engineering and the paper’s lead author. “It is real green energy, and unlike other so-called ‘green-energy’ sources, its production is totally green.”

New technique protects data on solid-state drives from radiation

Posted by in categories: computing, space

A new method of radiation-resistant computer data storage called watermark storage that’s been developed by a University of Alabama in Huntsville (UAH) professor leading a student team has direct applications in the nuclear power and space industries.

“Data-driven analytics are growing exponentially for space and nuclear environments,” says Dr. Biswajit Ray, an assistant professor of electrical and at UAH, a part of the University of Alabama System.

He says the new storage system doesn’t rely on an electronic charge for NAND flash storage, as traditional data drives do. NAND stands for the “not and” type of flash memory, which is in common use. Interestingly, the watermark storage method requires no new components.

In DNA, scientists find solution to building superconductor that could transform technology

Posted by in categories: biotech/medical, computing

Scientists at the University of Virginia School of Medicine and their collaborators have used DNA to overcome a nearly insurmountable obstacle to engineer materials that would revolutionize electronics.

One possible outcome of such engineered materials could be superconductors, which have zero electrical resistance, allowing electrons to flow unimpeded. That means that they don’t lose energy and don’t create heat, unlike current means of electrical transmission. Development of a superconductor that could be used widely at room temperature—instead of at extremely high or , as is now possible—could lead to hyper-fast computers, shrink the size of electronic devices, allow to float on magnets and slash energy use, among other benefits.

One such superconductor was first proposed more than 50 years ago by Stanford physicist William A. Little. Scientists have spent decades trying to make it work, but even after validating the feasibility of his idea, they were left with a challenge that appeared impossible to overcome. Until now.

A roadmap for the future of quantum simulation

Posted by in categories: computing, quantum physics

A roadmap for the future direction of quantum simulation has been set out in a paper co-authored at the University of Strathclyde.

Quantum computers are hugely powerful devices with a capacity for speed and calculation which is well beyond the reach of classical, or binary, computing. Instead of a binary system of zeroes and ones, it operates through superpositions, which may be zeroes, ones or both at the same time.

The continuously-evolving development of quantum computing has reached the point of having an advantage over classical computers for an artificial problem. It could have future applications in a wide range of areas. One promising class of problems involves the of quantum systems, with potential applications such as developing materials for batteries, industrial catalysis and nitrogen fixing.

Photovoltaic micro-inverter based on gallium nitride transistors

Posted by in category: computing

According to its designers, the device has a power density of 1.1 kW/L and an efficiency of 97%.

The micro-inverter utilizes GaN 600V diodes and power transistors developed by CEA’s electronic branch CEA-Leti. “With this coplanar technology, it would be possible to make the power component ‘smarter’ with protection (temperature, voltage, current, etc.) and control (driver) functions. It is also possible to design bidirectional voltage interrupters which do not exist at present,” the French scientists said in a statement.
