Summary: Polydiacetylene(PDA) supramolecules exhibit a conformation-dependent colorimetric response to external triggers, transitioning from the blue phase to the red phase. The study shows that PDA vesicles prepared at an intermediate purple phase exhibit a more sensitive colorimetric response to external triggers compared to those prepared at the blue phase. The supramolecular interactions, including inter- and intra-chain interactions, play a crucial role in causing chain distortions and structural rearrangements of the PDA backbone, in addition to repulsive-ionic head group interactions.

Summary: Polydiacetylene (PDA) has been developed as a colorimetric sensor with a unique color response to environmental stimuli. The stability and colorimetric response of blue phase PDA are influenced by noncovalent bonding and strong pi-pi interaction. This study demonstrates the potential of PDA as a colorimetric sensor for detecting subtle environmental changes and measuring the quality of polar organic solvents recovered from industrial effluent.

Summary: Polydiacetylene (PDA) exhibits unique color transition properties in response to external stimuli, making it a promising material for optical biosensors. However, the irreversible color transitions of most PDA materials limit their applications. This study demonstrates that the colorimetric reversibility of PDA is closely related to the difference in hydrogen bond strength and ionic interactions between adjacent headgroups of PDA vesicles. By comparing the reversibility of PDA vesicles with different terminal functional groups, it was found that specific compositions of PDA vesicles show noticeable color reversibility during thermal-photo stimuli cycles.

Summary: In this study, a reversible colorimetric response of polydiacetylenes to pH change was achieved through structural modifications on the monomer and extended photopolymerization time. Enhanced hydrogen bond forming headgroups and longer UV exposure reduced the response efficiency but enabled reversibility. This research provides a possibility for customized sensing applications.

Summary: By utilizing hyperspectral microscopy at visible wavelengths, we are able to present a spatial map of the structural distribution of polydiacetylene (PDA) at the nanoscale within a single crystal. It has been found that the structural variance of PDA, even under the same fabrication conditions, contributes to its poor reproducibility in chemo/biosensing. The tracking of the blue-to-red transition using this technique reveals distinct patterns left by heat or pH stimulation in the transition pathways.

Summary: This study investigated the responsiveness of nanovesicles under sonication using self-assembled polydiacetylene (PDA) as a chromic mechanoresponsive group. The results revealed that three factors, including greater shear stress, lower polymerization degree, and higher viscosity of the continue phase, promote the mechanochromism of the vesicles, highlighting the importance of actual capillary number in force response of nanovesicles.

Summary: Stimuli-responsive functional micro-/nanorobots (srFM/Ns) are intelligent, efficient, and promising microrobots that react to external stimuli and perform designated tasks. They have significant roles in targeted therapy, biological detection, tissue engineering, and other fields. However, there are few reviews focusing on them, hence the necessity of providing an overview of their current development to inspire further advancements in this field.

Summary: The development of fluorescent motifs that can reversibly and ratiometrically display mechano- and thermo-stimuli is attractive for monitoring the deformation or temperature of polymers. In this study, a series of excimer-type chromophores called Sin-Py (n = 1-3) was developed and incorporated into a polymer. The fluorescence of Sin-Py was controlled by the linker length, and the resulting fluorescent polymers, PU-Si2-Py and PU-Si3-Py, exhibited mechano- and thermo-responsive behavior. The mechanochromic response of the polymer films was due to the reversible suppression of excimer formation during mechanical deformation, while the thermochromic response indicated the glass transition temperature (Tg) of the polymers. This design provides a generally implementable way to develop dual-responsive polymers.

Summary: This study investigated the emotional response to vibrothermal stimulation by combining spatiotemporal vibrotactile stimulus with dynamic thermal stimulus. The results showed that vibrotactile patterns, duration, and dynamic temperature all independently affected emotional response. Increasing duration generally increased valence and arousal, while shifting from cold to hot generally decreased valence but had no significant effect on arousal. Certain spatiotemporal patterns exhibited unique responses to changes in dynamic temperature, indicating the potential for designing affective haptic interfaces using multimodal vibrothermal feedback.

Summary: The complexes of He, Ne, Ar, Kr, and Xe with B3N3H6 were investigated using MP2, CCSD(T), and SAPT ab initio methods. The complexes can be described as mono-, di-, and tri-coordinated to the N atoms, with stability following the order N-mono < N-di < N-tri. The interactions are dominated by dispersion and the binding energies are within the range of 1 or 2 kcal mol(-1). The results were compared with a recent DFT study on larger BN sheets complexes [Phys. Chem. Chem. Phys. 24 (2022) 2554-2566.].

Summary: It has been found that the introduction of buffer layers improves the electrical performance of solid oxide fuel cells (SSOFCs). In this study, varying ratios of Gd-doped CeO2 were used as buffer layers in YSZ-based SSOFCs. The results demonstrate that the performance of SSOFCs is enhanced when a buffer layer is added, with the highest performance achieved using Ce0.8Gd0.2O2-delta (GDC20) as the buffer layer. This suggests that the use of GDC series buffer layers is an attractive strategy to optimize performance loss due to electrolyte-electrode interactions.

Summary: This study investigates the influence of aspect ratio and quantum confinement on the single-photon and two-photon absorption cross-section of perovskite CsPbI3 nanorods. Experimental data shows that CsPbI3 nanorods have an extremely high two-photon absorption cross-section, significantly surpassing organic chromophores and other CsPbBr3 nanocrystals. Moreover, adjusting the aspect ratio can significantly enhance the absorption ability. Additionally, the study also reveals a moderate quantum confinement effect on the single-photon and two-photon absorption cross-section of the nanorods.
