Materials called perovskites can be more readily incorporated into silicon-based semiconducting platforms by using a microfluidic pumping technology developed at KAUST.
The perovskites currently being explored for many applications in new technologies are diverse materials sharing the same crystalline structure as the natural mineral perovskite. These semiconducting materials show great promise in a variety of optoelectronic applications, such as light emitters, sensors and solar cells.
Rutgers scientists for the first time have pinpointed the sizes of microplastics from a highly urbanized estuarine and coastal system with numerous sources of fresh water, including the Hudson River and Raritan River.
CORVALLIS, Ore. - Selectively cutting trees in riparian zones to aid forest restoration can be done without adversely affecting streams' water temperature as long as the thinning isn't too intensive, new research by Oregon State University shows.
Published in PLOS One, the study led by OSU College of Agricultural Sciences graduate student David Roon is one of the few to quantify restorative thinning's effects on forest streams.
An associate professor from RUDN University found out the effect of the number and size of pores on the permeability of bone implants by biological fluids. The results of the study could help choose the optimal physical parameters of implants. The results of the study were published in the International Journal of Engineering.
Osaka, Japan - Osaka University researchers employed machine learning to design new polymers for use in photovoltaic devices. After virtually screening over 200,000 candidate materials, they synthesized one of the most promising and found its properties were consistent with their predictions. This work may lead to a revolution in the way functional materials are discovered.
HIV infections are treated with antiviral drugs which effectively prevent the disease from developing. While pharmacological HIV therapy has advanced considerably, the virus cannot be entirely eliminated from the body with currently available drugs.
Without electronics and photonics, there would be no computers, smartphones, sensors, or information and communication technologies. In the coming years, the new field of phononics may further expand these options. That field is concerned with understanding and controlling lattice vibrations (phonons) in solids. In order to realize phononic devices, however, lattice vibrations have to be controlled as precisely as commonly realized in the case of electrons or photons.
Tohoku University scientists and their colleagues in Germany have revealed that a first-time exposure to only a brief period of brain hyperactivity resulted in an acute breakdown of the inter-cellular network of glial cells. Pharmacological intervention of the glial plasticity may provide a new preventative strategy for fighting epilepsy.
The findings were detailed in the Journal of Neuroscience.
Robots that could take on basic healthcare tasks to support the work of doctors and nurses may be the way of the future. Who knows, maybe a medical robot can prescribe your medicine someday? That's the idea behind 3D structural-sensing robots being developed and tested at Simon Fraser University by Woo Soo Kim, associate professor in the School of Mechatronic Systems Engineering.
Tokyo, Japan - Researchers from Tokyo Metropolitan University have revealed how liquid foams collapse by observing individual collapse "events" with high-speed video microscopy. They found that cracks in films led to a receding liquid front which sweeps up the original film border, inverts its shape, and releases a droplet which hits and breaks other films. Their observations and physical model provide key insights into how to make foams more or less resistant to collapse.
Clinical research requires that data be mined for insights. Machine learning, which develops algorithms to find patterns, has difficulty doing this with data related to health records because this type of information is neither static nor regularly collected. A new study developed a transparent and reproducible machine learning tool to facilitate analysis of health information. The tool can be used in clinical forecasting, which can predict trends as well as outcomes in individual patients.
Physicists from Russia, Chile, Brazil, Spain, and the UK, have studied how the magnetic properties change in 3D nanowires, promising materials for various magnetic applications, depending on the shape of their cross-section. Particularly, they more deeply probed into the Walker breakdown phenomenon, on the understanding of which the success of the implementation of the future electronics devices depends. The research outcome appears in Scientific Reports.

Preterm labor comprises 12.7% of all pregnancies. Although the overall rate of pregnancy is decreasing, the occurrence of premature birth due to preterm labor in south korea has been increasing over the past 7 years. Not only is preterm birth accountable for about a half of all neonatal mortality cases, the neurological deficits in surviving premature infants often lead to problems later in life, such as developmental disorders and respiratory complications.
Researchers at Oregon Health & Science University have demonstrated a new method of quickly mapping the genome of single cells, while also clarifying the spatial position of the cells within the body.
The discovery, published in the journal Nature Communications, builds upon previous advances by OHSU scientists in single-cell genome sequencing. The study represents another milestone in the field of precision medicine.
