Unveiling The First Precise MEMS Output Measurement Technique
2013-05-14 13:00:39

National Physical Laboratory New research being presented today at TechConnect World conference forms part of the European Commission backed Metrology for Energy Harvesting Project Tuesday 14th May, Washington DC - The commercial application of MEMS, or micro-electro-mechanical systems, will receive a major boost today following the presentation of a brand new way to accurately measure the power requirements and outputs of all existing and future devices. The cheap and easy to apply...

Device For Portable, Ultra-precise Clocks And Quantum Sensors Developed By Scientists
2013-05-09 10:59:35

University of Strathclyde In a joint project between the Universities of Strathclyde and Glasgow, Imperial College London and the National Physical Laboratory, researchers have developed a portable way to produce ultracold atoms for quantum technology and quantum information processing. Their research has been published in the journal Nature Nanotechnology, where it is featured on the front cover. Many of the most accurate measurement devices, including atomic clocks, work by...

A research team from NPL and the University of Edinburgh have invented a new way to zip and unzip DNA strands using electrochemistry. The DNA double helix has been one of the most recognizable structures in science ever since it was first described by Watson and Crick almost 60 years ago (paper published in Nature in 25 April 1953). The binding and unbinding mechanism of DNA strands is vital to natural biological processes and to the polymerase chain reactions used in biotechnology to copy...

New Device For Quantum Information Processing

A groundbreaking new device from the National Physical Laboratory could help to usher in the long-awaited era of quantum computers Researchers at NPL have demonstrated for the first time a monolithic 3D ion microtrap array which could be scaled up to handle several tens of ion-based quantum bits (qubits). The research, published in Nature Nanotechnology, shows how it is possible to realize this device embedded in a semiconductor chip, and demonstrates the device's ability to confine...

Research will lead to better more efficient harvesting devices Scientists working as part of the Metrology for Energy Harvesting Project have developed a new model to deliver the maximum power output for piezoelectric energy harvesters. Piezoelectric materials convert electrical energy into a strain (or vice-versa). The best known use of piezoelectricity is for medical ultrasound. Piezoelectric energy harvesters utilise energy from unwanted mechanical vibrations, such as the rattling...

Initial tests show promising results of new ultrasonic screening technique Scientists have successfully completed an initial trial of a new, potentially more reliable, technique for screening breast cancer using ultrasound. The team at the National Physical Laboratory (NPL), the UK's National Measurement Institute, working with the University Hospitals Bristol NHS Foundation Trust, are now looking to develop the technique into a clinical device. Annually, 46,000 women are diagnosed with...

This will help geologists temporally dissect Earth's history more faithfully New research by the National Physical Laboratory (NPL) and the Scottish Universities Environmental Research Centre (SUERC) will improve the accuracy of estimates of the time of geological events. The work centers on the calibration of one of the world's slowest clocks, known as the 'argon-argon clock'. The 'argon-argon clock' works by measuring the ratio of the amount of radioactive potassium in a sample of...

More accurate frequency standards technology are being developed to prevent interference on live TV services With government plans for a Digital Britain firmly underway, the amount of data that will be sent on the internet is set to increase dramatically. But with increased data comes the potential for increased frequency interference. This could mean data files and live "on-demand" TV services will be corrupted. If the scientists at the National Physical Laboratory (NPL) have their...

  Researchers have found that an atomic clock at the U.K.'s National Physical Laboratory (NPL) has the best long-term accuracy of any other clock in the world. Studies of the clock's accuracy show it is nearly twice as accurate as previously thought. The clock would lose or gain less than a second in about 138 million years. The NPL's CsF2 clock is a "caesium foundation" atomic clock, in which the "ticking" is provided by the measurement of the energy required to change a...

Comparing ultra high-resolution photographs from the past and the present could hold the key to restoring Hastings' fire-damaged pier On the 5th October 2010 the historic Hastings Pier was set on fire, destroying 95% of the Grade II listed building, leading to concerns over its future. Now scientists from the UK's National Physical Laboratory (NPL) are helping to show that the future of the pier is more positive than expected. Prior to the fire, NPL, the UK's National Measurement Institute,...
