Euclid, the European Space Agency’s dark Universe detective, has made an astonishing discovery – right in our cosmic backyard.

Certain advanced technologies, such as 3D displays, biosensing, and security printing, can utilize circularly polarized luminescence (CPL), which is produced when specific types of molecules are irradiated with UV light. The electric field of the CPL rotates in a spiral shape. Mechanical changes to these molecules, such as grinding, can induce a transition that creates a reversible emission color change. This is called mechanochromic luminescence (MCL). To improve CPL efficiency after grinding, researchers tested two different readily available compounds and how the CPL properties changed upon grinding.

Sixth-generation, or 6G, cellular networks are the next step in wireless communication, and electromagnetic terahertz waves are seen as crucial to its development. However, terahertz waves, with their higher frequency and shorter wavelength, are subject to greater interference from electromagnetic noise, making clear and secure transmission a challenge. Researchers from the University of Tokyo, as part of a multi-institution team, have now created an electromagnetic wave absorber for waves between 0.1–1 terahertz (THz). This greatly expands the range of the terahertz frequency which could be commercially used in the future. The ultrathin film is inexpensive, environmentally friendly and can be used outdoors, as it is resistant to heat, water, light and organic solvents.

Researchers from the School of Metallurgy and Environment at Central South University, together with their collaborators, have proposed a novel buried interface strategy for stabilizing zinc anodes. The zincophilic Sn layer is buried under the corrosion-resistant ZnS layer (SZS), which effectively solves the dendrite formation and corrosion problems. The zinc anodes coated with SZS exhibit significantly enhanced cycling stability and long-term performance. This buried interface engineering strategy offers a promising avenue for the rational design of zinc anodes in rechargeable batteries, potentially advancing energy storage technology.

Tokyo, Japan – Researchers from Tokyo Metropolitan University have elucidated how hydrogen and carbon monoxide is adsorbed into solids containing a crown-motif structure of platinum and gold. Using quick-scan X-ray absorption measurements and theoretical calculations, they studied a solid of [PtAu₈(PPh₃)₈]-H[PMo₁₂O₄₀] called PtAu8-PMo12 and found that gas adsorption is affected strongly by the dimension of nanoscale voids in the structure. This highlights the importance of engineering voids in materials for next generation sensors and gas separation.

'Temperamental' stars that brighten and dim over a matter of hours or days may be distorting our view of thousands of distant planets, suggests a new study led by UCL (University College London) researchers.
