X-ray detection is widely used in medical imaging, radioactivity detection, security checking, industrial flaw inspection, and so on. In recent years, metal halide perovskites have demonstrated excellent performances in the detection of X-rays and gamma-rays. However, most studies focus on perovskite single-pixel devices. To achieve the application goal of X-ray imagers, the detectors should be integrated with pixel circuits. This means that the device dark current is an important figure of merit to be considered. The low dark current can guarantee ...

WASHINGTON, March 14, 2023 – The amount of carbon dioxide in the atmosphere increases daily with no sign of stopping or slowing. Too much of civilization depends on the burning of fossil fuels, and even if we can develop a replacement energy source, much of the damage has already been done. Without removal, the carbon dioxide already in the atmosphere will continue to wreak havoc for centuries. Atmospheric carbon capture is a potential remedy to this problem. It would pull carbon dioxide out of the air and store it permanently to reverse the effects of climate change. Practical carbon capture technologies are still in the early stages of development, with the most promising involving ...

With the aid of some sea slugs, University of Nebraska–Lincoln chemists have discovered that one of the smallest conceivable tweaks to a biomolecule can elicit one of the grandest conceivable consequences: directing the activation of neurons. Their discovery came from investigating peptides, the short chains of amino acids that can transmit signals among cells, including neurons, while populating the central nervous systems and bloodstreams of most animals. Like many other molecules, an amino acid in a peptide can adopt one of two forms that feature the same atoms, with the same connectivity, but in mirror-image orientations: L and ...

OAK BROOK, Ill. – In a study of over a million women, digital breast tomosynthesis (DBT) showed improved breast cancer screening outcomes over screening with standard digital mammography alone. The results of the study were published in Radiology, a journal of the Radiological Society of North America (RSNA). Breast cancer is the most common cancer among women in the United States. While breast cancer mortality has been on the decline since the late 1980s due to improvements in early detection and treatment, it still remains the leading cause of cancer death among women. The five-year relative survival rate of breast cancer when it is detected early in its localized ...
