Though different fabrication approaches exist, two-step deposition is one of the main experimental techniques now used to make efficient, stable PSCs, especially on the industrial scale. The process involves first depositing lead iodide (PbI2) and then adding halide salts of monovalent cations such as methylammonium iodide (MAI) and formamidinium iodide (FAI) to convert it to perovskite.
Simon Fraser University researchers have designed a remarkably fast engine that taps into a new kind of fuel -- information.
The development of this engine, which converts the random jiggling of a microscopic particle into stored energy, is outlined in research published this week in the Proceedings of the National Academy of Sciences (PNAS) and could lead to significant advances in the speed and cost of computers and bio-nanotechnologies.
TORONTO, ON - Geoscientists at the University of Toronto (U of T) and Istanbul Technical University have discovered a new process in plate tectonics which shows that tremendous damage occurs to areas of Earth's crust long before it should be geologically altered by known plate-boundary processes, highlighting the need to amend current understandings of the planet's tectonic cycle.
New York, NY--May 11, 2021--Widely used to monitor and map biological signals, to support and enhance physiological functions, and to treat diseases, implantable medical devices are transforming healthcare and improving the quality of life for millions of people. Researchers are increasingly interested in designing wireless, miniaturized implantable medical devices for in vivo and in situ physiological monitoring. These devices could be used to monitor physiological conditions, such as temperature, blood pressure, glucose, and respiration for both diagnostic and therapeutic procedures.
2003 was a big year for virologists. The first giant virus was discovered in this year, which shook the virology scene, revising what was thought to be an established understanding of this elusive group and expanding the virus world from simple, small agents to forms that are as complex as some bacteria. Because of their link to disease and the difficulties in defining them--they are biological entities but do not fit comfortably in the existing tree of life--viruses incite the curiosity of many people.
Philadelphia, May 12, 2021 - In recent years there has been an increased interest in the consumption of kefir, a fermented dairy beverage, because there is some evidence that it has health benefits and its affordability.
A new study led by the Centre for Nutraceuticals in the University of Westminster shows that pink drinks can help to make you run faster and further compared to clear drinks.
The researchers found that a pink drink can increase exercise performance by 4.4 per cent and can also increase a 'feel good' effect which can make exercise seem easier.
For college students under pressure, a dog may be the best stress fighter around.
Programs exclusively focused on petting therapy dogs improved stressed-out students' thinking and planning skills more effectively than programs that included traditional stress-management information, according to new Washington State University research.
INDIANAPOLIS -- Artificial intelligence (AI)-driven healthcare has the potential to transform medical decision-making and treatment, but these algorithms must be thoroughly tested and continuously monitored to avoid unintended consequences to patients.
ROCHESTER, Minn. -- Patients diagnosed with post-COVID-19 syndrome, also known as "PCS," "COVID-19 long-haul syndrome" and "Post-Acute Sequelae of SARS COV-2," experience symptoms such as mood disorders, fatigue and perceived cognitive impairment that can negatively affect returning to work and resuming normal activities, according to a Mayo Clinic study published in Mayo Clinic Proceedings.
An international team of researchers at Great Ormond Street Hospital (GOSH), and University of California, Los Angeles (UCLA) have developed a gene therapy that successfully treated 48 out of 50 children with a form of severe combined immunodeficiency that leaves them without an immune system.
Saw-toothed grain beetles live in a symbiotic association with bacteria. Their bacterial partners provide important building blocks for the formation of the insect's exoskeleton, which protects the beetles from their enemies as well as from desiccation. In a new study, a team of scientists from the Johannes Gutenberg University in Mainz, the Max Planck Institute for Chemical Ecology in Jena, and the National Institute of Advanced Industrial Science and Technology in Japan demonstrates that glyphosate inhibits the symbiotic bacteria of the grain beetle.
Inks containing metal nanoparticles are among the most commonly-used conductive materials for printed electronics. Ink-jetting layers of MNP materials allows for unpreceded design flexibility, rapid processing and 3D printing of functional electronic devices such as sensors, solar panels, LED displays, transistors and smart textiles.
Researchers at the University of Bristol have discovered how microbes responsible for human African sleeping sickness produce sex cells.
In these single-celled parasites, known as trypanosomes, each reproductive cell splits off in turn from the parental germline cell, which is responsible for passing on genes. Conventional germline cells divide twice to produce all four sex cells - or gametes - simultaneously. In humans four sperms are produced from a single germline cell. So, these strange parasite cells are doing their own thing rather than sticking to the biology rulebook.
Every high-school physics student learns that sound and light travel at very different speeds. If the brain did not account for this difference, it would be much harder for us to tell where sounds came from, and how they are related to what we see.
Instead, the brain allows us to make better sense of our world by playing tricks, so that a visual and a sound created at the same time are perceived as synchronous, even though they reach the brain and are processed by neural circuits at different speeds.
