Companies across the world are competing fiercely to provide high-resolution displays to electronic devices such as TVs and smartphones. In particular, the virtual reality, a keyword of the 4th industrial revolution, requires a much higher resolution to improve the picture quality. A Korean research team developed a technology to produce a 'nano display' with a phenomenal resolution based on the 3D printing technique and posted the result of the study on a SCI journal, garnering much global attention.

Organic solar cells are ideal for use in flexible electronics because of the inherently malleable nature of semiconducting polymers. Recent research on the interplay between processing, thermodynamics and mechanical stability of typical photoactive layers in organic cells is providing a deeper understanding of these high-potential materials.

WASHINGTON, August 11, 2020 -- As we use resources, such as coal, oil, natural gas, copper, silicon and aluminum, to power massive computer farms and process digital information, our technological progress is redistributing Earth's matter from physical atoms to digital information -- the fifth state of matter, alongside liquid, solid, gas and plasma.

Children wearing multifocal contact lenses had slower progression of their myopia, according to results from a clinical trial funded by the National Eye Institute, part of the National Institutes of Health. The findings support an option for controlling the condition, also called nearsightedness, which increases the risk of cataracts, glaucoma and retinal detachment later in life. Investigators of the Bifocal Lenses In Nearsighted Kids (BLINK) Study published the results August 11 in the Journal of the American Medical Association.

Imagine plugging in to your brick house.

Red bricks -- some of the world's cheapest and most familiar building materials -- can be converted into energy storage units that can be charged to hold electricity, like a battery, according to new research from Washington University in St. Louis.

What The Study Did: This study sought to establish the rate of COVID-19 among health care workers through widespread screening for SARS-CoV-2 exposure in a large community hospital.

Authors: Allen Jeremias, M.D., M.Sc., of  St Francis Hospital in Roslyn, New York, is the corresponding author.

What The Study Did: Researchers performed a series of FFE (fitted filtration efficiency) evaluations for a wide range of 29 respirators and face masks used by health care facilities, including expired N95 respirators, N95 respirators that have undergone sterilization, imported respirators approved by the U.S. Centers for Disease Control and Prevention, respirators not listed as approved, and surgical or procedure masks with ties and ear loops in this quality-improvement study.

Researchers at Fudan University in Shanghai, China have developed three different techniques that successfully replace almost all malfunctioning microglia - each technique with its own advantage in application.

The researchers published their findings on Aug 11, 2020 in Cell Reports.

Materials scientists studying recharging fundamentals made an astonishing discovery that could open the door to better batteries, faster catalysts and other materials science leaps.

CAMBRIDGE, MA -- At the height of a thunderstorm, the tips of cell towers, telephone poles, and other tall, electrically conductive structures can spontaneously emit a flash of blue light. This electric glow, known as a corona discharge, is produced when the air surrounding a conductive object is briefly ionized by an electrically charged environment.

For centuries, sailors observed corona discharges at the tips of ship masts during storms at sea. They coined the phenomenon St. Elmo's fire, after the patron saint of sailors.

Of ever-increasing concern for operating a tactical communications network is the possibility that a sophisticated adversary may detect friendly transmissions. Army researchers developed an analysis framework that enables the rigorous study of the detectability of ultraviolet communication systems, providing the insights needed to deliver the requirements of future, more secure Army networks.

Scientists have been warning about an "insect apocalypse" in recent years, noting sharp declines in specific areas -- particularly in Europe. A new study shows these warnings may have been exaggerated and are not representative of what's happening to insects on a larger scale.

SCOTTSDALE, Ariz. -- Aug 11, 2020 -- Working with an international team of researchers, HonorHealth Research Institute and the Translational Genomics Research Institute (TGen), an affiliate of City of Hope, were instrumental in one of the first clinical trials showing how pancreatic cancer patients can benefit from immunotherapy, according to a four-year study published in a premier scientific journal, Nature Medicine.

Despite disproportionately higher rates of COVID-19 infection, hospitalization and death among people of color, minority groups are significantly underrepresented in COVID-19 clinical trials, according to a new perspective authored by faculty from the University of Georgia and University of Colorado and pharmacists from Phoebe Putney Memorial Hospital in Albany.

Scientists at the University of Bath have taken an important step towards understanding the interaction between layers of atomically thin materials arranged in stacks. They hope their research will speed up the discovery of new, artificial materials, leading to the design of electronic components that are far tinier and more efficient than anything known today.
