Organic light emitting diodes (OLEDs) have matured to commercial level. Yet, their widespread market adoption is hindered due to high costs and complicated device architecture. Researchers are actively exploring innovative device engineering strategies to circumvent these issues. Narayanan Unni and co-workers have tried to address the above challenges by exploiting a concept called exciplex. Exciplex emission is possible at the interface of two different materials which may not be luminescent themselves. This provides an opportunity to use relatively cheaper materials instead of costly fluorescent or phosphorescent emitter materials. They ...

Sixty percent of US physicians serving as panel and task force members for the American Psychiatric Association’s official manual of psychiatric disorders received payments from industry totalling $14.24m, finds a study published by The BMJ. Because of the enormous influence of diagnostic and treatment guidelines, the researchers say their findings “raise questions about the editorial independence of this diagnostic manual.” Often referred to as the ‘bible’ of psychiatric disorders, the Diagnostic and Statistical Manual of Mental Disorders, fifth edition, text revision (DSM-5-TR) ...

Women who suffer depression during or after pregnancy have a higher risk of death by both natural and unnatural causes, a new study of childbirth in Sweden published in The BMJ reports. The increased risk peaks in the month after diagnosis but remains elevated for as long as 18 years afterwards. Women who develop perinatal depression, which is to say depression during pregnancy or shortly after childbirth, are generally twice as likely to die of natural or, as in most cases, unnatural causes. They are six times more likely to commit than women without this form of depression. The increase ...

UNIVERSITY PARK, Pa. — Moore's Law, a fundamental scaling principle for electronic devices, forecasts that the number of transistors on a chip will double every two years, ensuring more computing power — but a limit exists. Today's most advanced chips house nearly 50 billion transistors within a space no larger than your thumbnail. The task of cramming even more transistors into that confined area has become more and more difficult, according to Penn State researchers. In a study ...

Hummingbirds use two distinct sensory strategies to control their flight, depending on whether they’re hovering or in forward motion, according to new research by University of British Columbia (UBC) zoologists.  “When in forward fight, hummingbirds rely on what we call an ‘internal forward model’—almost an ingrained, intuitive autopilot—to gauge speed,” says Dr. Vikram B. Baliga, lead author of a new study on hummingbird locomotion published in Proceedings of the Royal Society B. ...

In nature, organic molecules are either left- or right-handed, but synthesizing molecules with a specific “handedness” in a lab is hard to do. Make a drug or enzyme with the wrong “handedness,” and it just won’t work. Now chemists at the University of California, Davis, are getting closer to mimicking nature’s chemical efficiency through computational modeling and physical experimentation.   In a study appearing Jan. 10 in Nature, Professor Dean Tantillo, graduate students William DeSnoo and Croix Laconsay, and colleagues at the Max Planck ...

Overdose deaths in North America have skyrocketed, primarily because of the spread of illegally manufactured fentanyl. In a new study, researchers analyzed an early and prominent fentanyl-selling operation on the dark web. The organization sustained a significant growth rate, which allowed it to offer consumers steep discounts. In light of these findings, the authors conclude that it might be challenging to constrain supply by shuttering individual organizations since remaining organizations could grow rapidly to fill unmet demand. The study was conducted by researchers at Carnegie ...
