Summary: Chiral metamaterials hybridized with tunable materials or active components can flexibly manipulate the asymmetric transmission of electromagnetic waves. This study proposes the concept of a direction-reversible tunable asymmetric transmission effect realized by chiral metamaterials. The designed structure consists of twisted metallic meta-sheets incorporated with active diodes, allowing the direction of asymmetric transmission to be switched in real-time by external bias voltage and the polarization of the transmitted wave to be controlled.

Summary: Multifunctional materials are of great interest in research. Organic-inorganic hybrid perovskites are commonly used in designing these materials due to their versatile properties and adaptable composition. By introducing chiral groups as ligands, it becomes easier to enhance the photoelectric properties. In this study, chiral one-dimensional organic-inorganic hybrid perovskites, namely (R/S-3-HP)PbBr3 (1R/1S) (3-HP=3-hydroxy-piperidine), were synthesized, exhibiting reversible phase transition at 349/336 K. Excited by light at 339 nm, 1R and 1S emitted orange light with a broad peak at 635 nm. Additionally, they possessed an indirect bandgap of 3.29 eV and SHG intensity comparable to KDP. This work offers a new approach to the design of multifunctional chiral perovskite materials.

Summary: Au nanoparticles (AuNPs) are combined with D-methionine (D-Met) through Au-S bond, and then self-assembled with chitosan (CS) via electrostatic driving. The chirality of the resulting Au-D-Met/CS can be reversed depending on the ratio of D-Met to CS, as revealed by circular dichroism spectra. Due to the high electrical conductivity of AuNPs and the intrinsic chirality of D-Met and CS, the obtained Au-D-Met/CS is used as an electrochemical chiral sensing platform for the discrimination of tryptophan (Trp) enantiomers.

Summary: Analysis of the coronal gyrus from fossil and extant carnivorans shows that early pinnipeds, such as Potamotherium, may have used their whiskers for foraging. This study provides insights into the underwater foraging behavior of early pinnipeds and highlights the importance of adaptations for survival in marine habitats. The reliance on whiskers appears to be an ancestral feature that favored the transition of pinnipeds from terrestrial to amphibious marine species.

Summary: Long-persistent luminescence (LPL), also known as afterglow, is a phenomenon where a material continues to emit light after the excitation source is turned off. It has attracted much interest due to its fundamental nature and potential in developing new functional materials. Most current LPL materials are complex inorganic systems that require harsh synthetic procedures and rare-earth metals. However, metal-free organic long-persistent luminescence (OLPL) has gained interest as it overcomes some of the disadvantages of inorganic systems. The most successful method to generate OLPL systems is through binary donor-acceptor exciplex systems, but the ratios of the binary systems can complicate reproducibility and large-scale production. Therefore, simpler OLPL systems are needed for easier design and production.

Summary: Drug-induced liver injury (DILI) is a common cause of acute liver failure in the USA and Europe, but most cases can be recovered or prevented by discontinuing the offending drug. Recent research has found that peroxynitrite (ONOO-) can be used as a potential indicator for early diagnosis of DILI, and there is an urgent need to establish a method to detect and track peroxynitrite in DILI cases. In this study, a FRET-based nano fluorescent probe CD-N-I was developed, which showed high selectivity and sensitivity in detecting peroxynitrite. The probe successfully detected exogenous peroxynitrite in live cells and endogenous peroxynitrite in APAP-induced liver injury of HepG2 cells.
