Exhaust systems have changed dramatically over the years, from the simple single-muffler systems from cars of the '50s and '60s, to the active exhaust systems from select late model cars like the 2025 ...

Researchers have developed a novel type of nanomechanical resonator that combines two important features: high mechanical quality and piezoelectricity. This development could open doors to new ...

Researchers have built a tiny butterfly-shaped optical resonator to improve the sensitivity of ultrafast measurements of electron beam pulses. They found that the enhancement allows less intense ...

·Proposed a new paradigm for nanoantenna design using coupled-mode theory. ·Designed an OC-Hµ resonator with excellent sensing performance. ·Using OC-Hµ resonators for biomolecule recognition and ...

Ceramic resonators and filters occupy a practical middle ground in frequency control and signal conditioning, offering designers cost-effective alternatives to quartz crystals and LC networks. Built ...

In either the 1850s or 1860s, German physicist Hermann von Helmholz created a device to analyze sound. In 2005, that same sort of device made its way into the airbox of the new 3.8-liter flat-six of ...
