An international team, led by Tongji University and Beijing Institute of Technology, together with University of Oviedo, demonstrates the possibility of converting linear incident polarization to any polarization state on demand and over a broadband frequency range. In particular, the appearance of chiral dipoles at the exceptional point presents a new degree of freedom for manipulating hyperbolic polaritons.

Researchers from Nanjing University and the Army Engineering University of PLA have published a review in ExRNA, shedding light on the critical role of exosomes in diabetic cardiomyopathy (DCM). Exosomes are nanoscale vesicles involved in cell-to-cell communication and carry bioactive molecules, such as proteins, lipids, and microRNAs (miRNAs), which are essential in DCM progression. This paper summarizes the underlying mechanisms of DCM and discusses exosomes as potential diagnostic tools and therapeutic targets.

In a paper published in the National Scientific Review, researchers used 25 years of data to build machine learning models. They analyzed the spatial and temporal variation in soil microbial-derived carbon (MDC) stocks, and predicted MDC stocks under different shared socioeconomic paths in the future.This work revealed that every 1°C temperature increase leads to 6.7 Pg decline in global soil MDC in predictable regions. Projected future MDC stocks are expected to decline globally, with a drop of 6-37 Pg by 2100, depending on socioeconomic pathways. They recommend integrating the response of MDC stocks to warming into socioeconomic models to enhance confidence in selecting sustainable pathways.

In a paper published in Polymer Science & Technology, an international team of scientists

explores how modifying side-chain features in homopolypeptides affects their ability to form coacervates. They synthesized various polypeptide variants, revealing that changing the lengths of side-chain amino or linker segments was found either to prohibit coacervate formation or to allow adjustment of the phase transition temperature. Notably, anionic polypeptides also formed coacervates, expanding potential applications in biomimetic materials. This work paves the way for designing multifunctional polymers with tunable properties. This study is led by Timothy J. Deming (Department of Chemistry and Biochemistry and Department of Bioengineering, University of California, Los Angeles, United States).

The growing focus on enhancing color quality in LCDs,OLEDs and Micro-LED has spurred significant advancements in color-conversion displays. This article provides a comprehensive review of different types of color conversion methods and color conversion materials. We summarize the current status of patterning process, discuss key strategies to enhance display performance, and speculate on the future prospects and roles that color conversion will play in ultra-high-definition micro- and projection displays.

Hydrogen-powered planes are set to take wing around the world in the future. To make this possible, engineers have to develop the jet engines that will power them. Experiments by researchers at ETH Zurich are now providing the necessary basis for making these engines powerful and durable.
