Single-particle spectroscopy of CsPbBr3 perovskite reveals the origin low electrolumine

Researchers have used the method of single-particle spectroscopy to study electroluminescence in light-emitting devices. They discovered that efficient charge funneling between individual perovskite nanocrystals and the phenomenon of emission blinking are responsible for the low efficiencies of perovskite light-emitting devices.

No soil left behind: How a cost-effective technology can enrich poor fields

Many farmers across sub-Saharan Africa try to coax crops out of sandy soils that are not ideal for holding water and nutrients. Traditional approaches would have them apply more fertilizers and use irrigation, but both require access to resources and infrastructure that many do not have. A relatively new technology modeled for eight African countries, and currently being tested in Zimbabwe, shows potential for improving harvests through increased water retention and accumulation of organic material.

How do the strongest magnets in the universe form?

How do some neutron stars become the strongest magnets in the Universe? Astrophysicists have found a possible answer to the question of how these so-called magnetars form. Researchers have used large computer simulations to demonstrate how the merger of two stars creates strong magnetic fields. If such stars explode in supernovae, magnetars could result.

Siblings of problem gamblers also impulsive, prone to risk-taking

Biological siblings of people with gambling disorder also display markers of increased impulsivity and risk-taking, according to a new psychology study. The findings suggest people with gambling disorder — a psychiatric term for serious gambling problems — may have pre-existing genetic vulnerabilities to the illness.

Important questions on how mental illness is currently diagnosed

This research raises questions as to whether current diagnoses accurately reflect the underlying neurobiology of mental illness. The findings, just published in the leading peer-reviewed medical journal, JAMA Psychiatry, highlight the need for more individualised approaches to defining mental illness.

Vaping-associated lung injury findings

A clinical perspective article reviews various imaging manifestations of electronic nicotine delivery systems such as e-cigarettes, vape pens, and hookah tanks. Despite the lack of a standardized case definition for vaping-associated lung injury, the radiologist may be the first person to prompt the clinical team to ask about relevant exposures like hypersensitivity pneumonitis, diffuse alveolar hemorrhage, acute eosinophilic pneumonia, organizing pneumonia, lipoid pneumonia, and giant cell interstitial pneumonia.
