Graphene and 2-D materials could move electronics beyond ‘Moore’s law’

Posted by in categories: computing, mobile phones, nanotechnology, particle physics

A team of researchers based in Manchester, the Netherlands, Singapore, Spain, Switzerland and the U.S. has published a new review on a field of computer device development known as spintronics, which could see graphene used as building block for next-generation electronics.

Recent theoretical and experimental advances and phenomena in studies of electronic spin transport in and related two-dimensional (2-D) materials have emerged as a fascinating area of research and development.

Spintronics is the combination of electronics and magnetism, at the nanoscale and could lead to next generation high-speed electronics. Spintronic devices are a viable alternative for nanoelectronics beyond Moore’s law, offering higher energy efficiency and lower dissipation as compared to conventional electronics, which relies on charge currents. In principle we could have phones and tablets operating with spin-based transistors and memories.

The mystery is over: Greek mathematician successfully solves 78-year-old maths problem

Posted by in category: mathematics

A Greek mathematician has found the answer to a mind boggling maths problem that has remained unanswered for 78 years – until now.

Associate Professor of Mathematics Dimitris Koukoulopoulos together with Oxford University research professor James Maynard, has solved the Duffin and Schaeffer Conjecture.

First expressed in 1941 by mathematicians R J Duffin and A C Schaeffer, the last time a mathematician showed promise in solving the problem was in 1990. But it wouldn’t be until 29 years later that it would be fully proven by Koukoulopoulos and Maynard – two relatively young mathematicians, both aged in their 30’s.

How DNA and RNA subunits might have formed to make the first genetic alphabet

Posted by in categories: biotech/medical, genetics

Understanding the prebiotic origins of the nucleic acids is a long-standing challenge. The latest experiments support the idea that the first nucleic acid encoded information using a mixed ‘alphabet’ of RNA and DNA subunits. RNA and DNA nucleosides might have emerged together on prebiotic Earth.

This New Electric Jet Concept Uses Air Friction to Generate Power

Posted by in categories: energy, finance

Instead of fossil fuel or large battery banks, Eather One will be powered by air friction across its wings and airframe. That kind of renewable, on-demand energy is a radical proposition.

Up to 81% of COVID-19-Positive Patients are Asymptomatic: Study

Posted by in category: biotech/medical

In a paper published in the journal Thorax, a team of Australia researchers described the first instance of complete COVID-19 testing of all passengers and crew on an isolated cruise ship during the current pandemic: of the 217 passengers and crew on board, 128 tested positive for COVID-19 on reverse transcription-PCR; of the COVID-19-positive patients, only 24 (19%) were symptomatic.

Volkswagen T2 Camper Van Electric Conversion

Posted by in categories: business, transportation

A couple of months ago I introduced you to a UK company that converts classic cars to electric propulsion. The company, named eDub Services, was founded by a young man named Kit Lacey, and since my piece on his business, he and I have been in conversation about this fascinating field of entrepreneurship. I have an old Volvo 240 in my garage that one day will need an electric drivetrain for sure, so getting acquainted with someone like Kit is a good bet.

I talked to Kit about the concrete and chronological information on his rebuilds and how we could make it accessible for all of us curious about how such projects can be carried out. This series is the result, in Kit Lacey’s own words. So let’s begin at the beginning.
