Researchers have developed a novel way to noninvasively measure and map how and where trapped light vibrates within microscale optical resonators. Visualizing the vibration patterns will help scientists to perfect ultrasensitive optical sensors for detecting biomolecules and even single atoms.
adminResearchers have succeeded in visualizing changes in defect density on the surface of GaN through the laser terahertz emission microscope (LTEM) which measures THz waves generated by laser emission. The discovery shows that LTEM is useful as a new method for evaluating the quality of wide-gap semiconductors and it is also expected that LTEM will bring a breakthrough in the development of next-generation optical devices, super high frequency devices, and energy devices.
adminThere were many experiments with gas engines in the 19th century but the first practical engine was built by the Belgian engineer tienne Lenoir in 1860. The best known builder…
adminResearchers are developing technology to make pacemakers battery-free. The advancement is based upon a piezoelectric system that converts vibrational energy — created inside the chest by each heartbeat — into electricity to power the pacemaker.
Noise from pile driving during offshore wind turbine construction could be damaging the hearing of harbour seals around the UK, researchers have found. They say more research is needed on how noise affects marine mammals’ hearing and into engineering solutions to reduce noise levels.
adminScientists have developed the first autonomous industrialized public lighting system that works with solar and wind energy.
Researchers have revealed precisely how much different slipstreaming tactics reduce drag on a horse during a race.
