Digital cameras as well as many other electronic devices need light-sensitive sensors. In order to cater for the increasing demand for optoelectronic components of this kind, industry is searching for new semiconductor materials. They are not only supposed to cover a broad range of wavelengths but should also be inexpensive. A hybrid material, developed in Dresden, fulfils both these requirements. Himani Arora, a physics PhD student at Helmholtz-Zentrum Dresden-Rossendorf (HZDR), demonstrated that this metal-organic framework can be used as a broadband photodetector.
Acyl fluorides are organic compounds that contain a fluorine atom in their structure. These compounds have recently gained much attention in transition-metal catalysis due to their stability and selective reactivity. However, their commercial production remains a challenge. A group of researchers in Tokyo have found a way to generate complex acyl fluorides from widely available acyl fluorides through a reversible reaction, with the rare metal palladium at the core of this process.
WEST LAFAYETTE, Ind. - A new tool for medical professionals may help shed more light on tumors in the body and how the brain operates.
Purdue University researchers created technology that uses optical imaging to better help surgeons map out tumors in the body and help them understand how certain diseases affect activity in the brain. The work is published in the journal IEEE Transactions on Medical Imaging.
There is plenty of scientific evidence that the health of a mother can impact the health of her child. Now a Northwestern University study flips that relationship around: Researchers have discovered the health of the fertilized embryo determines the functional health of the mother, which has implications for healthy aging, stress resilience and suppression of protein damage.
Essentially, a bad egg does good by protecting the mother from cellular stress, ensuring she lives longer and is healthy enough to produce the next generation.
Greek and Norwegian researchers have conducted a study on the health conditions in six refugee camps in Greece.
"We found high levels of trauma," says Professor Terje A. Eikemo.
He heads the Centre for Global Health Inequalities Research (CHAIN) at the Norwegian University of Science and Technology (NTNU). CHAIN collaborated with the National Center for Social Research in Athens, and others, to survey refugee health.
Infrared radiation, which is invisible yet highly utilizable, is used in various fields and for various purposes, such as for coronavirus detection (i.e. through thermal imaging cameras and biosensors). A Korean research team has developed a technology that visualizes infrared radiation and expands its application range.
Nipple-sparing mastectomy is gaining ground as a treatment or preventive measure for breast cancer, given the understandable desire among patients to preserve natural appearance as much as possible. But the precise risk of preserving the nipple is not known as the cancer can spread along mammary ducts and to the nipple. A three-dimensional picture of the nipple structure can elucidate much more clearly than conventional reconstructions whether, where, and how much the cancer has spread to the nipple.
Warming at the Third Pole has increased vegetation growth that can, in turn, slow down warming.
The Third Pole has seen an increase in vegetation over the past three decades. This phenomenon, also known as "greening," may help slow rapid local warming, according to an invited review paper published in the inaugural issue of Nature Reviews Earth & Environment.
Men pose more risk to other road users than women do and they are more likely to drive more dangerous vehicles, reveals the first study of its kind, published online in the journal Injury Prevention.
The findings prompt the researchers to suggest that greater gender equity in road transport jobs, overall, might help lessen these risks.
Road safety analysis has traditionally focused on an individual's injury risk from their own use of a particular type of transport rather than the risk that might be posed to others.
New research in JNeurosci explores how a particular region of the brainstem might explain differences in attention in people with autism.
There's a new disease-detecting technology in the lab of Sanjiv "Sam" Gambhir, MD PhD, and its No. 1 source of data is number one. And number two.
The Casimir Force is a well-known effect originating from the quantum fluctuation of electromagnetic fields in a vacuum. Now an international group of researchers have reported a counterpoint to that theory, adding to the understanding of energy fluctuations within fluids.
Some substances are known to exist in several different structurally disordered solid states, a phenomenon known as polyamorphism.
The first and perhaps most celebrated example of polyamorphic behavior was discovered in water ice in 1984 by Mishima et al. Two different forms of amorphous water ice were identified, known as low-density amorphous and high-density amorphous ices. Later on, similar phenomena were also observed in other important systems such as Si, SiO2, and GeO2.
BIRMINGHAM, Ala. - Human cells respond to stresses like DNA damage, metabolic imbalance and starvation by first trying to repair the problem. If that does not work, the cells then induce programmed cell death, called apoptosis. Apoptosis is a highly regulated cell fate decision that removes about 50 billion to 70 billion cells each day in adults.
A previous study has shown that a type of squill growing in Madeira produces a chemical compound that may be useful as a medicinal drug. But a new study from researchers at Uppsala University has shown that this is probably not true: instead, the plant had likely accumulated antibiotics from contaminated soil.
