The fast pace of growing computing power could be sustained for many years to come thanks to new research from the UK's National Physical Laboratory (NPL) that is applying advanced techniques to magnetic semiconductors. Moore's Law observed that the density of transistors on an integrated circuit doubles every two years. Components have shrunk over time to achieve this, but experts believed that when the characteristic transistor size reduces below ~ 20 nm, heating and quantum effects will...

Scientists at the UK's National Physical Laboratory (NPL) in Teddington have designed a high-speed thermometer that can measure the temperature inside explosions without being damaged in the impact. The shockwave, heat, soot and debris from an explosion can damage thermometers. Conventional thermocouples do not react quickly enough to capture the information. This makes modeling the interaction of an explosion with its environment problematic "“ as temperature is essential in any...

A government lab in Teddington has taken on its biggest sample for analysis to date "“ a 14 ton foot-bridge.The National Physical Laboratory (NPL) is a world-leading center of excellence in developing and applying the most accurate measurement standards, science and technology. For over 100 years it has been the UK's National Measurement Institute and provides highly accurate measurement and analysis for public and private sector benefit alike. The "sample" was a 14 ton footbridge that...

25 years of pollution monitoring shows a fall in the presence of toxins in ambient airAir quality in the UK has improved significantly over the last 25 years according to a report published by the National Physical Laboratory (NPL). Monitoring at 17 testing sites around the UK shows a fall in the presence of harmful heavy metals such as lead, iron and copper in the air we breathe. Results show a 70% reduction in the average presence of all heavy metals tested over the period. The total...
