Systems for capturing and converting carbon dioxide from power plant emissions could be important tools for curbing climate change, but most are relatively inefficient and expensive. Now, researchers at MIT have developed a method that could significantly boost the performance of systems that use catalytic surfaces to enhance the rates of carbon-sequestering electrochemical reactions.
Halogen atoms (Cl and Br) strongly influence the atmospheric chemical composition. Since 1970s, scientists discovered that these atoms were responsible for depletion of ozone in the stratosphere and ground-level ozone of the Arctic. In the past decade, there is emerging recognition that halogen atoms also play important roles in tropospheric chemistry and air quality. However, the knowledge of halogen atoms in continental regions is still incomplete.
Research team at Seoul National University (Prof. Tae-Woo Lee) and University of Pennsylvania (Prof. Andrew M. Rappe) developed perovskite light-emitting diodes (PeLEDs) with an external quantum efficiency (EQE) of 23.4%. The research results were published in Nature Photonics, which is the world-renowned international academic journal, on January 4th (Title: Comprehensive defect suppression in perovskite nanocrystals for high-efficiency light-emitting diodes).
Male breast cancer patients were found to have a high prevalence of cardiovascular conditions, in a small study of this rare patient population presented at the American College of Cardiology's Advancing the Cardiovascular Care of the Oncology Patient Virtual course.
EAST LANSING, Mich. - An international team of researchers led by Michigan State University's Morteza Mahmoudi has developed a new method to better understand how nanomedicines -- emerging diagnostics and therapies that are very small yet very intricate -- interact with patients' biomolecules.
PHILADELPHIA, PA - January 25, 2021 - Opertech Bio, Inc., today announced the publication of a seminal research article describing the application of its pioneering TāStation® technology to the pharmacological characterization of human taste discrimination. The findings are published in the peer-reviewed Journal of Pharmacology and Experimental Therapeutics, JPET.
The carbon footprint of plastic production for initial use is greater than the global warming impact of the entire process used for medical device reprocessing
Use of reprocessed devices is environmentally superior to use of original products in 13 of 16 categories evaluated
Reprocessing found to advance "circular economy," a key strategy for reaching the UN Sustainability Goals
By 2050, most people on Earth will live downstream of tens of thousands of large dams built in the 20th century, many of them already operating at or beyond their design life, according to a UN University analysis.
The report, "Ageing water infrastructure: An emerging global risk," by UNU's Canadian-based Institute for Water, Environment and Health, says most of the 58,700 large dams worldwide were constructed between 1930 and 1970 with a design life of 50 to 100 years, adding that at 50 years a large concrete dam "would most probably begin to express signs of aging."
Predictions of future climate change require a clear and nuanced understanding of Earth's past climate. In a study published today in Science Advances, University of Hawai'i (UH) at Mānoa oceanographers fully reconciled climate and carbon cycle trends of the past 50 million years--solving a controversy debated in the scientific literature for decades.
Throughout Earth's history, global climate and the global carbon cycle have undergone significant changes, some of which challenge the current understanding of carbon cycle dynamics.
The Singapore University of Technology and Design (SUTD) and its research collaborators have successfully demonstrated the four-dimensional (4D) printing of shape memory polymers in submicron dimensions which are comparable to the wavelength of visible light. This novel development has allowed researchers to now explore new applications in the field of nanophotonics.
4D printing enables 3D printed structures to change its configurations over time and is used in a wide variety of fields such as soft robotics, flexible electronics, and medical devices.
It's mid-January 2021, and the first gray whales from the eastern North Pacific population have started to arrive in the breeding lagoons in Baja California, Mexico. Since the start of their southbound migration from their high latitude feeding grounds, several sightings of emaciated gray whales have already been reported along their migration route.
Metagenomics - the study of genetic material from an environmental sample - is growing as species evolve or are discovered across the globe. To correlate the newly developed microbiomes with existing data sets, a team of researchers based in China has developed the Microbiome Search Engine 2 (MSE 2). It was published on Jan. 19 in mSystems, a journal of the American Society for Microbiology.
The tracking of eye movement is one of the key elements of virtual and amplified reality technologies (VR/AR). A team from MSU together with a professor from RUDN University developed a mathematical model that helps accurately predict the next gaze fixation point and reduces the inaccuracy caused by blinking. The model would make VR/AR systems more realistic and sensitive to user actions. The results of the study were published in the SID Symposium Digest of Technical Papers.
Good news for the green transition: Flowery diets help predatory insects help farmers keep pests in check
Predatory insects have been shown to live longer when they have access to nectar and pollen, according to a new study by researchers at the University of Copenhagen. Thus, flowers don't just benefit insects, they help farmers farm sustainably. Predatory insects are skilled pest controllers whose hunting reduces the need for agricultural pesticides.
Popular in aquariums all over the world, the zebrafish is native to South Asia. But here in a Cincinnati Children's Hospital Medical Center's laboratory, the freshwater variant plays a vital role in scientific discovery.
