Summary: Spin-orbit coupling is believed to be necessary for observing the chirality-induced spin selectivity (CISS) effect in a chiral medium. Recent studies, however, suggest that CISS can occur even in the absence of spin-orbit coupling due to an orbital polarization effect. In this study, a chirally functionalized carbon nanotube network is used as the chiral medium to examine these concepts. The results show that the CISS effect can still be observed in a transverse measurement geometry that nullifies electromagnetochiral contributions, indicating that the CISS effect may not be solely explained by electromagnetochiral effects.

Summary: In the study, the researchers focused on the morphology control of amphiphilic rod-coil molecules composed of the rigid hexaphenyl unit and flexible oligoethylene and butoxy groups. They found that the position of the methyl side chain influenced the driving force during the self-assembly process, determining the tilted packing direction. Interestingly, the molecules aggregated into long helical nano-fibers, which further formed nano-sheets or nano-tubes at higher solution concentrations. The hierarchical-chiral assembly amplified chirality and played a crucial role in the enantioselective nucleophilic substitution reaction.

Summary: This study investigates how halogenation influences protein or peptide folding and self-assembly hierarchically using halogen bonding mediated self-assemblies on cyclodipeptide scaffolds. The results show that single-functionalized cyclodipeptides (Cyclo-GX) form homochiral helical nanotubes via consecutive X center dot center dot center dot O bonds independent of halogen kinds. In contrast, double-functionalized cyclodipeptides (Cyclo-XX) exhibit versatile self-assembly architectures depending on the para-substituents, leading to nanotubular, lamellar, and triple helical nanotubular structures. It is also found that halogen substitution affects molecular folding, packing, and chirality at hierarchical levels. Additionally, clusteroluminescence and circularly polarized luminescence with tunable handedness are achieved in the cyclodipeptides by controlling halogen substituents.

Summary: The facile synthesis of chiral materials is crucial for various applications. Supramolecular preorganization has been proven effective for synthesizing carbon and carbon nitride-based materials with ordered morphology and controlled properties, but the transfer of chirality from supramolecular assemblies to the final material was not previously demonstrated. In this study, large-scale synthesis of chiral CN materials capable of enantioselective recognition was achieved by designing supramolecular assemblies with intact chirality at elevated temperatures. The optimized chiral CN showed enantiomeric preference and CN electrodes exhibited stereoselective interactions with enantiomeric probes in electrochemical measurements, confirming the potential of using supramolecular precursors for producing carbon and CN materials and electrodes with designed chemical properties.

Summary: It is challenging to construct multifunctional chiral stimulus-responsive molecules and modulation of their nanoscale morphology. In this paper, a novel chiral molecule with photoactive and potentially bioactive properties was synthesized. The morphological changes of its self-assembly were influenced by solvent polarity and light exposure. The synthesized molecule underwent efficient Z-E isomerization under light irradiation by introducing highly oriented hydrogen bonds into the cyanostilbene part. The resulting morphological changes from nanohelices to vesicles with chiroptical evolution provide a green and efficient method for designing responsive chiral materials.

Summary: Chirality transfer plays a vital role in the structure and functionality of biological systems. By adjusting the kinetic factors, such as deposition rate and heat treatment, different chiral 2D assemblies can be synthesized on the Au(111) surface from achiral molecules, resulting in enantiomeric entities. The results demonstrate that chirality transfer and induction in biological assemblies can be controlled by altering the kinetic factors, providing insights and practical approaches for the design of complex biomolecular superstructures.

Summary: The study investigates the propagation of chirality in soft matter using computer simulations. The preferred twist of the assembled structures is determined during the initial stage of self-assembly, and it is regulated by the entropy gain of either the polymer, the rods, or both.

Summary: Reflectance anisotropy spectroscopy (RAS) is widely used in the investigation of organic compounds, especially porphyrins and porphyrin-related compounds, due to its unique characteristics. The CD-RAS technique, which measures the circular dichroism of samples, allows for the study of the anisotropy of the optical properties under circularly polarized light. The open structure and flexibility of this new spectrometer make it suitable for coupling with UHV systems or other experimental configurations. In this manuscript, the CD-RAS technique is detailed and calibration tests with chiral porphyrin assemblies are reported to validate the results obtained using a commercial spectrometer.

Summary: Circularly polarized luminescence (CPL) has gained significant interest for its potential applications in chiral photonic techniques and optoelectronic materials science. The dissymmetry factor (g(em)) plays an essential role in evaluating the properties of CPL-active materials. Recent studies have shown that chiral supramolecular co-assemblies can effectively enhance the g(em) value through the ordered helical superstructure of chiral building blocks. The chirality transfer and induction mechanism in this assembly process promote the amplification effect of induced CPL in achiral dyes.

Summary: Supramolecular short-peptide assemblies are important biomaterials used in biomedical applications. These materials can self-assemble into chiral hierarchical structures triggered by various stimuli. The resulting supramolecular chirality can modulate protein and cell interactions. Recently, research has focused on developing chiral materials with potential spintronic applications. By combining different chiral sources, such as homochiral peptides and glucono-delta-lactone, researchers have shown that the supramolecular chirality and spin signal can be modulated. This study opens up new possibilities for developing CISS-based spintronic devices and circuits.

Summary: An improvement scheme for high-strength bolt dry-type joints was proposed, and a new type of common bolt dry-type joints were designed. A pseudo test involving low-cycle repeated loading was conducted to assess the seismic resistance properties of new joints, and numerical simulation was applied to validate the rationality of experimental results. It was found that under certain conditions, the deformation of the bolt no longer significantly increases, while the end block of the beam begins to show large cracks and has good energy dissipation performance.
