UK researchers find way to reduce power consumption of transistors in computer chips

University of Kentucky researchers have discovered a means of reducing gate leakage current of transistors in computer chips that will permit chip producers to continue developing more efficient and powerful chips with reduced power consumption.

Zhi Chen, associate professor of electrical and computer engineering, found that applying rapid thermal processing directly on gate insulators – used to control current flow of transistors in computer chips – can dramatically reduce the chips&#1

Dusty Story

In the mine, like in medicine, prevention is the best way of treatment. It means that it is easier to prevent an explosion than to fight with its consequences, which unfortunately turn sometimes into disasters. Explosion in coal mines happen, as a rule, because of accumulation of combustion agent – natural gas and/or slack – in the air underground. The natural gas and/or slack may explode spontaneously – simply because its concentration in the air has reached the critical value. To learn how much

Titania nanoparticles could lead to improved sensors and solar energy

Time evolution of the thermal properties during dehydration of sol-gel titania emulsions

Nanostructured titania (TiO2) has been extensively studied as a very promising material for applications in sensors, photocatalysis, solar energy conversion and optical coatings. As the properties of titania are determined by its different phases (i.e. rutile and anatase) and these phases depend upon the synthesis method employed, it is important to understand the change in properties that oc

Can a standby label cut power consumption?

Everybody complains about high energy prices. And yet it’s so easy to save electricity – simply by switching off electrical appliances completely, rather than leaving them ’idling’ in standby mode. The Fraunhofer Institute for Systems and Innovation Research ISI has been investigating possible ways of raising consumers’ awareness of the energy they waste by leaving appliances switched on.

In a single year, the electrical equipment in German households and offi

Yale engineers make standardized bulk synthesis of nanowires possible

A team of Yale scientists have demonstrated a method to understand effective synthesis of semiconductor nanowires (NWs) for both their quality and quantity, according to a report published in the journal Nanotechnology.

Graduate student Eric Stern in the department of biomedical engineering along with his colleague Guosheng Cheng, associate research scientist in electrical engineering systematically varied and tested parameters for producing GaN NWs using an optical lithograp

Have these experts drilled the world’s smallest hole?

Experts at Cardiff University have developed machinery so sophisticated that they can drill a hole narrower than a human hair.

Such precision has potentially major benefits in medical and electronic engineering.

The experts at the University’s multi-award-winning Manufacturing Engineering Centre, are drilling holes as small as 22 microns (0.022 mm) in stainless steel and other materials.

The human hair varies between 80 microns (0.08 mm) down to 50 microns
