Very Long Wave Infrared Quantum Dot Photodetector up to 18 μm
Chinese Academy of SciencesColloidal quantum dots (CQD) are of interest for optoelectronic devices because of the wide energy gap tunability from ultraviolet to infrared wavelengths.

In a landmark development for environmental conservation, a pioneering plasmonic photocatalyst has been engineered to synergistically degrade the potent pollutants hexavalent chromium (Cr(VI)) and norfloxacin from aquatic environments.
Exploring quantum heat engines is vital for designing highly efficient power systems beyond classical limits and for understanding quantum thermodynamics. Scientists demonstrate the first implementation of chiral thermodynamic cycles and quantum state transfers in a trapped ion by dynamically encircling a closed loop excluding Liouvillian exceptional points.
For the practical application of 2D semiconductors, it is crucial to construct high-quality p-n junctions. Scientist in China developed a low-energy ion implantation system for constructing 2D lateral p-n homojunction. The conductivity type of WS2 was successfully realized to transform from n-type conduction to p-type conduction, and the universality of this method was demonstrated.
A new study from the Violence Prevention Research Program at UC Davis suggests that gun-free zones may reduce the risk of mass shootings.
For the first time since X-rays were discovered, researchers have successfully performed X-ray spectroscopy to identify the element of a single atom at a time. The achievement takes advantage of improvements to synchrotron X-ray light sources.
New study reveals how an unexpected genetic mechanism influences the evolution of butterfly wing coloration.
A recent study finds that hope appears to be more beneficial than mindfulness at helping people manage stress and stay professionally engaged during periods of prolonged stress at work. The study underscores the importance of looking ahead, rather than living “in the moment,” during hard times.
An electro-optic duplex memristor on a GaN/AlScN hetero-structure based Schottky diode has been realized. This two-terminal memristor shows good electrical and opto-electrical nonvolatility and reconfigurability.
Surprising details about mosquito mating could lead to improved malaria control techniques and help develop precision drone flight. A paper published Aug. 30 in Current Biology revealed that when a male Anopheles coluzzii mosquito hears the sound of female-specific wingbeats, his eyes “activate” and he visually scans the immediate vicinity for a potential mate.
