To create more energy-efficient clouds and crunch Big Data faster, we need a new generation of technologies including novel transistors. But before we can put these future technologies into mass production, we need new techniques for prototyping below 30 nanometers—the size where prototyping becomes increasingly difficult.

NASA’s Lunar Atmosphere and Dust Environment Explorer (LADEE) literally ‘saw the light’ just days before crashing into the lunar farside last Thursday April 17. Skimming just a few kilometers above the moon’s surface, mission controllers took advantage of this unique low angle to gaze out over the moon’s horizon in complete darkness much like the Apollo astronauts did from lunar orbit more than 40 years ago.

Description The LTM®4624 is a complete 4A step-down switching mode μModule® (micromodule) regulator in a tiny 6.25mm × 6.25mm × 5.01mm BGA package. Included in the package are the switching controller, power FETs, inductor and support components. Operating over an input voltage range of 4V to 14V or 2.375V to 14V with an external bias […]

(Phys.org) —A team of researchers at the University of Minnesota, along with assistance from several African wildlife agencies, has found that contrary to popular belief, cheetahs are able to maintain population levels when sharing space with lions. In their paper published in the Journal of Animal Ecology, the team describes how they performed an analysis of cheetah and wild dog survivability in lion areas using data from prior field studies.

We all might have fond (or maybe not so fond) memories of the first MCU we used, but where does that device and the many others that you may have also used and read about. So we asked MCU manufacturers to tell us which of their MCU lines has been the most popular ever and […]

Treating cadmium-telluride (CdTe) solar cell materials with cadmium-chloride improves their efficiency, but researchers have not fully understood why. Now, an atomic-scale examination of the thin-film solar cells led by the Department of Energy’s Oak Ridge National Laboratory has answered this decades-long debate about the materials’ photovoltaic efficiency increase after treatment.

Don´t let yourself get confused by miniature dimensions – small SMT LEDs produce surprisingly strong light. SMT LEDs enjoy a big popularity because of their size but also thanks to a fast and simple assembly to PCB on automatic machines. In comparison to wire-leaded types, a vast majority of SMT LEDs doesn´t contain optics, thus […]

Cougars may have survived the mass extinction that took place about 12,000 years ago because they were not particular about what they ate, unlike their more finicky cousins—the saber-tooth cat and American lion. Both perished along with the woolly mammoth and many of the other supersized mammals that walked the Earth during the late Pleistocene.

Last month, scientists announced the first hard evidence for cosmic inflation, the process by which the infant universe swelled from microscopic to cosmic size in an instant. This almost unimaginably fast expansion was first theorized more than three decades ago, yet only now has “smoking gun” proof emerged.

Medical diagnostic systems such as personal health assistants, designed for the home care environment would be economically, and socially beneficial. As the result, early disease treatment by detection of abnormalities could reduce hospitalization costs, doctor visits, health care labor force and improve the quality of life. Continuing the previous research, we build the multi-functional device, […]
