Debraj Ray in a 2010 research paper

This is a nice way to tell about the tunnel effect.

#TunnelEffect #Frustration #DebrajRay #research #world

You’re in a multi-lane tunnel, all lanes in the same direction, and you’re caught in a serious traffic jam,” wrote Ray. “After a while, the cars in the other lane begin to move. Do you feel better or worse? At first, movement in the other lane may seem like a good sign: you hope that your turn to move will come soon, and indeed that might happen. You might contemplate an orderly move into the moving lane, looking for suitable gaps in the traffic. However, if the other lane keeps whizzing by, with no gaps to enter and with no change on your lane, your reactions may well become quite negative. Unevenness without corresponding redistribution can be tolerated or even welcomed if it raises expectations everywhere, but it will be tolerated for only so long. Thus, uneven growth will set forces in motion to restore a greater degree of balance, even (in some cases) actions that may thwart the growth process itself.

Time Crystals

#research #timecrystals #physics #quantumtheory #ChristopherMonroe

Last Year Christopher Monroe decided to try creating a time crystal. Initially when Nobel prize winning physicist Frank Wilczek proposed the concept in 2012, other researchers proved that there was no way to create such a thing.

Time Crystals are hypothetical structures that pulse without requiring any energy – like a ticking clock that never needs winding. The pattern repeats in time in much the same way that the atoms of a crystal repeat in space.

Christopher Monroe, a physicist at University of Maryland, along with his team used chains of atoms they had constructed for other purposes to make a version of a time crystal.

Another group led by researchers at Harvard, created time crystals out of dirty diamonds.

They are first examples of a remarkable type of matter – a collection of quantum particles that constantly changes, and never reaches a steady state. These systems draw stability from random interactions that would normally disrupt other kinds of matter.

Faster and efficient computers?

#research #technology #computers #UK #microfluidics

Researchers form the University of Exeter in the UK have developed an innovative new method to engineer computer chips more easily and cheaper than conventional methods.

Optoelectronic materials, devices that produce, detect and control light, that form an integral part of the next generation of renewable energy, security and defense technologies could benefit a great deal from this discovery.

The research team used microfluidics technology, which uses a series of minuscule channels in order to control the flow and direction of tiny amounts of fluid. The fluid contains graphene oxide flakes, that are mixed together in the channels, to construct the chips.

First-ever Space Technology research institutes (STRI)!

#NASA #STRI #Research #Space #Institute #Technology

NASA has taken steps for the creation of two multi-disciplinary, university-led research institutes. The aim of these institutes will be to focus on the development of technologies critical to extending human presence deeper into our solar system.

Each of the STRI will be receiving an amount of $15 million over the period of 5 years. The two institutes are:

  • Center for the utilization of biological engineering in Space (CUBES)
  • Institute for Ultra-Strong composites by computational design (US-COMP)

It is anticipated that advances in laboratories could quickly translate to advances in manufacturing facilities with the help of industrial partners.

Convert heat into electricity!

Previously researchers from Ohio State University in the US pioneered the use of a quantum mechanical effect to convert heat into electricity. Now, they have figured out how to make their technique work in a form more suitable to industry.

The researchers used magnetism on a composite of nickel and platinum to amplify the voltage output 10 times or more. This time it was a thicker piece of material that more closely resembled components of future electronic devices.

Many devices, including car engines produce heat as a byproduct. This is usually called waste heat. Solid-state thermoelectrics aims to capture the waste heat inside specially designed materials to generate POWER, thus increasing overall energy efficiency.

The researchers were able to increase the output for a composite of nickel with a sprinkling of platinum, from a few nano-volts to tens or hundred of nano-volts. This required no nano-fabrication and can be readily scaled up for industry. Read the full article here.
