A team of researchers from Osaka University, in cooperation with Tokyo Institute of Technology, directly observed charge transfer and intermolecular interactions in artificial photosynthesis that occurs on a picosecond (ps) scale (10-12). With time-resolved attenuated total reflection (TR-ATR) spectroscopy in the terahertz (THz) region, they revealed the process of artificial photosynthesis material [Re(CO)2(bpy) {P(OEt)3}2](PF6) in Triethanolamine (TEOA) solvent as a reductant. Their research results were published in Scientific Reports.
Researchers at Tokyo University of Agriculture and Technology (TUAT) in Japan and Mount Allison University in Canada have developed a more efficient method to produce the building blocks needed for antibiotics and cancer treatment drugs.
They published their peer-reviewed results online on August 16 ahead of the September 14 print edition of Chemical Communications, a journal of the Royal Society of Chemistry.
The building blocks the researchers set out to better develop are called polyene substructures.
Physicists created a new way to fabricate special kinds of electronic components known as spintronic devices. These high-performance, low-power devices have a promising future, so efficient ways to make them are highly sought after. The new fabrication method is interesting because it uses organic molecules which are relatively easy to configure for different purposes. Layers of molecules could be painted or printed onto metals to create new electronic functions.
DALLAS, Sept. 12, 2019 -- An advanced Magnetic Resonance Imaging (MRI) brain scan analysis in patients with stroke-related, small vessel disease helped predict problems with thinking, memory and even dementia, according to new research published in Stroke, a journal of the American Stroke Association, a division of the American Heart Association.
Researchers from University of Tennessee, IESEG School of Management, and Georgia State University published a new paper in the Journal of Marketing that investigates the role of firms' customer engagement initiatives in social media and analyzes how firms seek to influence digital sentiment by shaping customers' experiential interactions.
New research shows that the presence of microplastics can stunt the growth of earthworms, and even cause them to lose weight - potentially having a serious impact on the soil ecosystem.
The study, to be published in the journal Environmental Science & Technology, is the first to measure the effects of microplastics on endogeic worms, which live in the top soil.
UCSF Benioff Children's Hospitals have successfully treated a months-old infant with a rare childhood leukemia using a targeted therapy approved for adults with inoperable liver cancer and advanced kidney cancer.
The decision to use the drug, sorafenib, was made after pathologists identified a unique mutation in the form of two genes being fused together instead of on separate chromosomes -- according to a case study publishing in the journal Leukemia on Sept. 11, 2019.
Fibrosis, the damaging build-up of hardened or scarred tissue in the body, is a hallmark of various diseases and can lead to the dysfunction and failure of organs such as the heart and kidney. Fibrosis-related diseases in various organs contribute to around 45 per cent of deaths in developed countries.
SALT LAKE CITY, September 11, 2019--John A. Moran Eye Center physician-researcher Paul S. Bernstein, MD, PhD, and his patients at the University of Utah played a key role in the recent discovery of the first genetic cause for a rare eye disease.
ALBUQUERQUE, N.M. -- Experimenting at 4.1 million degrees Fahrenheit, physicists at Sandia National Laboratories' Z machine have found that an astronomical model -- used for 40 years to predict the sun's behavior as well as the life and death of stars -- underestimates the energy blockage caused by free-floating iron atoms, a major player in those processes.
The blockage effect, called opacity, is an element's natural resistance to energy passing through it, similar to an opaque window's resistance to the passage of light.
EVANSTON, Ill. -- An international team of astronomers, including Northwestern University's Farhad Yusef-Zadeh, has discovered one of the largest structures ever observed in the Milky Way. A newly spotted pair of radio-emitting bubbles reach hundreds of light-years tall, dwarfing all other structures in the central region of the galaxy.
The team believes the enormous, hourglass-shaped structure likely is the result of a phenomenally energetic burst that erupted near the Milky Way's supermassive black hole several million years ago.
EPFL scientists are developing new approaches for improved control of robotic hands - in particular for amputees - that combines individual finger control and automation for improved grasping and manipulation. This interdisciplinary proof-of-concept between neuroengineering and robotics was successfully tested on three amputees and seven healthy subjects. The results are published in today's issue of Nature Machine Intelligence.
Modern atomic clocks are the most accurate measurement tools currently available. The best current instruments deviate by just one second in 30 billion years. However, even this extraordinary level of precision can be improved upon. Indeed, a clock based on an excited nuclear state of thorium-229 should make it possible to enhance timing accuracy by another order of magnitude.
Groundwater is essential for growing crops, but new research shows climate change is making it harder for soil to absorb rainfall.
While the idea that soil particles rearrange themselves in response to environmental conditions is not new, scientists once thought these shifts in the ground happened slowly. Not anymore.
Nocturnal and diurnal mammals see the same - but only for a brief time. When mice are born, the chromatin in the cells of their eyes has a diurnal structure. Day by day, the layout of this chromatin slowly inverts, allowing the mice to see at night. How this change happens was a mystery.
