A method for calculating optimal parameters of liquid chrystal displays developed at RUDN University
A professor from RUDN University together with his colleagues from Saratov Chernyshevsky State University and D. Mendeleev University of Chemical Technology of Russia developed a method for calculating the parameters of diffraction optical elements used in LCDs. In particular, the new technology can be used to expand the angle of view while preserving high resolution and color rendition. The results of the study were published in the Journal of The Society for Information Display.
Blood draws are no fun.
They hurt. Veins can burst, or even roll -- like they're trying to avoid the needle, too.
Oftentimes, doctors use blood samples to check for biomarkers of disease: antibodies that signal a viral or bacterial infection, such as SARS-CoV-2, the virus responsible for COVID-19; or cytokines indicative of inflammation seen in conditions such as rheumatoid arthritis and sepsis.
A professor from RUDN University together with his Indian colleagues synthesized and studied new dibenzophenazine-based liquid crystals that could potentially be used in optoelectronics and solar panels. The results of the study were published in the Journal of Molecular Liquids.
PROVIDENCE, R.I. [Brown University] -- Metallurgists have all kinds of ways to make a chunk of metal harder. They can bend it, twist it, run it between two rollers or pound it with a hammer. These methods work by breaking up the metal's grain structure -- the microscopic crystalline domains that form a bulk piece of metal. Smaller grains make for harder metals.
In a new publication from Cardiovascular Innovations and Applications; DOI https://doi.org/10.15212/CVIA.2019.1263, Yao Dong, Jun-E Liu and Ling Song from the Capital Medical University, Beijing, China consider risk factors for intraoperative pressure injury in aortic surgery.
Less than two days of water quality sampling at local beaches may be all that's needed to reduce illnesses among millions of beachgoers every year due to contaminated water, according to new Stanford research. The study, published in Environmental Science & Technology, presents a modeling framework that dependably predicts water quality at beaches after only a day or two of frequent water sampling.
Real-world materials are usually messier than the idealized scenarios found in textbooks. Imperfections can add complications and even limit a material's usefulness. To get around this, scientists routinely strive to remove defects and dirt entirely, pushing materials closer to perfection. Now, researchers at the University of Illinois at Urbana-Champaign have turned this problem around and shown that for some materials defects could act as a probe for interesting physics, rather than a nuisance.
New research has found that growing up in a bilingual home can provide unexpected cognitive benefits later in life.
The study, published in the journal Scientific Reports, demonstrates for the first time that adults who acquired their second language as a young child (early bilinguals) are quicker at shifting attention and quicker at detecting visual changes compared to adults who learnt their second language later in life (late bilinguals).
Young rugby league players could benefit from individualised nutrition plans to maximise performance and optimise recovery throughout their careers, according to QUT researchers.
The new study, published in the International Journal of Sport Nutrition and Exercise Metabolism, provides nutritional recommendations and considers potential supplements to improve players' physical capacity, health and recovery during the preparatory and competition phases of a season.
Nanofiltration (NF) is an advanced technology for treating wastewater containing organic micropollutants (OMPs).
Recently, a research group led by Prof. WAN Yinhua from the Institute of Process Engineering (IPE) of the Chinese Academy of Sciences developed a stable graphene oxide nanofiltration membrane with uniform pore size to remove OMPs.
The study was published in Chemical Engineering Journal on Jan. 20.
A new collaborative study led by researchers at the National Institute for Environmental Studies, the University of Tokyo, and Michigan State University exposes the role of dams for mitigating flood risk under climate change.
Loneliness in adults aged 50 and over during the COVID-19 lockdown was linked to worsening depressive and other mental health symptoms, according to a large-scale online study.
Loneliness emerged as a key factor linked to worsening symptoms of depression and anxiety in a study of more than 3,000 people aged 50 or over led by the University of Exeter and King's College London, and funded by The National Institute for Health Research (NIHR) Maudsley Biomedical Research Centre (BRC) .
The Ganges River - with the combined flows of the Brahmaputra and Meghna rivers - could be responsible for up to 3 billion microplastic particles entering the Bay of Bengal every day, according to new research.
A modelling study suggests that demand for cancer surgery will rise by 52% - equal to 4.7 million procedures - between 2018 and 2040, with the greatest relative increase in low-income countries, which already have substantially lower staffing levels than high-income countries.
HOUSTON - (Jan. 21, 2021) - Where did Earth's nitrogen come from? Rice University scientists show one primordial source of the indispensable building block for life was close to home.
The isotopic signatures of nitrogen in iron meteorites reveal that Earth likely gathered its nitrogen not only from the region beyond Jupiter's orbit but also from the dust in the inner protoplanetary disk.
