University of Delaware researchers have developed a silicon-based device that can convert some light into electricity using a germanium-carbon alloy. The device, which was tested with laser light, showed a conversion rate of 1.4 percent and demonstrated efficient rectification numbers. This breakthrough has the potential to bridge the ...
University of Delaware scientists have discovered that firefly larvae use light signals to ward off predators, rather than coloration. The research suggests an aposematic display, warning predators of an unappetizing meal.
A three-step program has been shown to keep drug offenders cleaner and out of prison, with graduates staying straight longer than those who received no treatment. The study compared prisoners who completed a prison-based treatment program with those who participated in a community-based program.
New data from the University of Delaware reveals that solar wind is not a simple, wave-like entity but rather a dynamic phenomenon with complex fluctuations. Understanding these fluctuations may enable prediction of cosmic disturbances and provide warnings for astronauts and utility companies.
Despite financial gains by some African Americans, racism may be getting worse in the US due to individual and institutional barriers. Expert James M. Jones recommends six steps to reduce prejudice, including joint cooperation, intergroup contact, and a greater appreciation of individual differences.
Researchers find that centrosymmetric materials can exhibit triboluminescence when containing impurities or structural anomalies, challenging traditional understanding of the phenomenon. The study synthesized various esters to investigate the relationship between material structure and triboluminescent activity.
Researchers at the University of Delaware have developed a new theory on how chemical additives alter the growth rate of silicon and silicon-germanium alloys. By understanding this mechanism, they hope to improve the control of electronic properties in films grown from chemical vapors at low temperatures.
Researchers have identified a mechanism to trap key industrial metals such as nickel, copper and zinc in soils, reducing their mobility. This discovery could lead to more effective cleanup techniques using traditional methods.
University of Delaware researchers use a 'bicyclic lactone' to synthesize five unique compounds derived from red sea algae, making them easier to access for potential pharmaceutical uses. The process allows for efficient synthesis in large quantities, paving the way for further research into the compounds' biological activity.
A new software developed by UD researchers can generate a simulated version of reforming scenarios in just 100 CPU seconds, improving the accuracy and speed of modeling catalytic reforming processes. The NetGen reforming software allows researchers to build models in a day instead of months.
Researchers developed a microelectrode that can measure multiple chemical species simultaneously in seawater biofilms, including dissolved oxygen, iron, manganese, and iodide. The device is hardy enough to withstand various marine settings and can detect pollutants at low levels.
A new algorithm using transformations can optimize robotic movements, reducing calculation time by up to 10-fold. This technique may enable robots to perform tasks more efficiently in space and on Earth, such as satellite repairs and inspection tasks.
The ancient port of Berenike continued to operate for centuries longer than previously thought, with entrepreneurs keeping costs low to maximize profits. Traders brought in luxury goods like elephants, gold, and red coral, while also exporting essential items like frankincense and Indian pepper.
