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

Learning from Nature – First Self-Organizing Electronic Systems Developed

Professor Peter Hofmann and his team at the Competence Center Electrical and Electronic (EE) Architecture at the Technische Universität Dresden (TU Dresden) have successfully developed the first self-organizing electronic components. These so called autonomous units form the basis for complex technical systems of the future. For this purpose, the scientists have adopted the knowledge of complex systems found in nature.

Organisms are structured according to the modular assembly concept –

Sensors Made in Dresden for Aerospace and Medicine

Currently, the Institute of Aerospace Engineering at the Technische Universität Dresden (TU Dresden) is developing an innovative sensor system for human respiratory investigations which can also be applied in the space. Professor Stefanos Fasoulas and his expert team have created a high-performance miniaturised sensor which enables a simultaneous in-situ measurement of oxygen, carbon dioxide and volume flow rates.

In this regard, scientists of the Professorship for Space Systems and

Additives may save energy for cooling big buildings

A National Institute of Standards and Technology (NIST) researcher has come up with a method designed to improve the energy efficiency of water chillers that cool the nation’s large commercial buildings. The NIST method, if confirmed through experiments with full-scale chiller systems, could save as much as 1 percent of the 320 billion kWh of electricity used annually by chillers or an equivalent 920,000 barrels of oil a day, according to Mark Kedzierski, the NIST mechanical engineer who dev
