Many sensors, such as flow sensors and those used in medical diagnostics, rely on microfluidic devices. However, mixing and pumping fluids becomes challenging because of the small size of these devices. As an alternative to traditional actuation methods, surface acoustic waves (SAWs) can ... 詳細を見る

Designing power transmission lines requires accounting for many factors: mechanical stress due to environmental conditions and hardware loads, performance testing, and--of course--electrical analysis. Transmission line hardware contains both insulating and conducting assemblies. One ... 詳細を見る

With technological advancements accelerating so rapidly, more powerful computer chips are needed to meet the high demands of fast-growing industries. Lam Research Corporation manufactures semiconductor devices and equipment used to deposit, etch, and clean material layers laid onto ... 詳細を見る

Stent insertion through the coronary artery is a common procedure used to treat restricted blood flow to the heart caused by stenosis. Following the procedure, restenosis may occur due to excessive tissue growth around the stent. Researchers at Boston Scientific are using multiphysics ... 詳細を見る

To ensure astronaut safety on space missions, it is necessary to routinely revitalize the atmosphere in manned spacecraft. Jim Knox, Rob Coker, and a team of engineers at the NASA Marshall Space Flight Center have developed a water-saving system called an Isothermal Bulk Dessicant (IBD). ... 詳細を見る

Nanoresonators, or optical nanoantennas, manage the concentration, radiation, and absorption of light at the nanometer scale and show stunning promise for future improvements to technology, such as sensors, computers, and other electronics. However, the ways that these devices scatter ... 詳細を見る

Carbon fiber composites are used extensively throughout the body of modern aircraft, such as the Boeing 787 Dreamliner, because of their exceptional strength and light weight. Expanded metal foil (EMF) is added to the composite structure layup as a protective measure to dissipate the ... 詳細を見る

The process of continuous casting has transformed steel production, saving valuable resources while improving steel quality and process efficiency. Continuous casting involves carrying molten refined steel to a caster. There, water-cooled copper molds are used to form steel strands that ... 詳細を見る

As part of an industry that saves lives on a regular basis, pharmaceutical companies are in need of systems that can be used to deliver high-quality medicines. One method utilizes sound waves generated by an acoustic levitator with foam-coated transducers. Using the acoustic force from ... 詳細を見る

In response to the increasing awareness of the risks associated with the proliferation of nuclear materials, the Global Threat Reduction initiative has called for research reactors currently using highly enriched uranium (HEU) fuel to be converted to low-enriched uranium (LEU) fuel. The ... 詳細を見る
