The efficiency of solar-to-energy conversion in semiconductors is limited by charge carrier recombination, often via defect-induced gap states. Although some materials exhibit an intrinsic defect ...

The paper presents a design procedure based on simplified finite element analyses (FEAs) to compare the performances of different magnetization schemes for short-stroke tubular linear permanent magnet ...

The story of South Africa’s sardine migration is brought vividly to life on camera. Each summer, the sardine run sees billions of sardines traveling up the coast, providing a feast for an array ...
