Organic semiconductors are materials that find applications in various electronic devices. Exciton binding energy is an important attribute that influences the behavior of these materials. Now, researchers have employed advanced spectroscopic techniques to accurately determine these energies for various organic semiconductor materials, with a high precision of 0.1 electron volts. Their study reveals unexpected correlations that are poised to shape the future of organic optoelectronics, influence design prin Read more ›

Researchers have developed a material to remove urea from water and potentially convert it into hydrogen gas. By building these materials of nickel and cobalt atoms with carefully tailored electronic structures, the group has unlocked the potential to enable these transition metal oxides and hydroxides to selectively oxidize urea in an electrochemical reaction. The team's findings could help use urea in waste streams to efficiently produce hydrogen fuel through the... Read more ›

Southern Africa contains the vast majority of the world's remaining populations of both black and white rhinoceroses (80% and 92%, respectively). The region's climate is changing rapidly as a result global warming. Traditional conservation efforts aimed at protecting rhinos have focused on poaching, but until now, there has been no analysis of the impact that climate change may have on the animals. A research team has recently reported that, though... Read more ›

Three different HIV antibodies each independently protected monkeys from acquiring simian-HIV (SHIV) in a placebo-controlled proof-of-concept study intended to inform development of a preventive HIV vaccine for people. The antibodies -- a human broadly neutralizing antibody and two antibodies isolated from previously vaccinated monkeys -- target the fusion peptide, a site on an HIV surface protein that helps the virus fuse with and enter cells.

The warming climate has not lead to an expected increase in atmospheric moisture over arid and semi-arid regions of the world. The finding, which has surprised scientists, indicates that some regions may be even more vulnerable to future wildfires and extreme heat than projected. Read more ›

A team has developed a new measurement method that, for the first time, accurately detects tiny temperature differences in the range of 100 microkelvin in the thermal Hall effect. Previously, these temperature differences could not be measured quantitatively due to thermal noise. Using the well-known terbium titanate as an example, the team demonstrated that the method delivers highly reliable results. The thermal Hall effect provides information about coherent multi-particle states... Read more ›

Researchers have developed a 10-centimeter-diameter glass metalens that can image the sun, the moon and distant nebulae with high resolution. It is the first all-glass, large-scale metalens in the visible wavelength that can be mass produced using conventional CMOS fabrication technology. Read more ›

To function properly, the genetic material is highly organized into loop structures that often bring together widely separated sections of the genome critical to the regulation of gene activity. Scientists now address how these loops can help repress or silence gene activity, with potentially far-reaching effects on human health. Read more ›

Due to the substantial clinical demand for artificial small-diameter vessels (SDVs), numerous commercial products have emerged. However, the majority of existing artificial SDVs lack an endothelial layer, leading to thrombosis. Fabricating artificial SDVs with a consistently uniform endothelial layer and adequate mechanical properties has proven exceptionally challenging. A research team has now induced spontaneous cell assembly and endothelialization through internal pores. Read more ›

A study has found that older adults who exercise with their spouse achieve lower physical activity levels than older adults without their spouse. In a study of 240 participants in Singapore aged 54 to 72 years old, the researchers also found that those who received personalized feedback on their fitness trackers were more active than those who did not.
