However, in 2017, a unique polar phase, the ferroelectric nematic (NF), is confirmed. Subsequently, in 2024, the revolutionary spontaneous mirror symmetry breaking of ferroelectric twist-bend nematic chiral structures (NTBF phase) is demonstrated. Nematic LCs are commonly used as optically active matrices for luminescent dyes, allowing the fine-tuning of emission properties through external fields. In this manuscript, the pioneering temperature-tunable lasing studies utilizing commercial dyes doped into a mixture that displays the NTBF phase within an exceptionally low-temperature range of 34-43.3 °C are shown. The subsequent experiments explore how lasing characteristics within NTBF and NF phases can be employed in a single, compact device to produce multicolor and white lasers. Furthermore, there are introduced spontaneously formed emissive fibers from the NTBF phase. As perspectives, the voltage-dependent increase of lasing intensity in NF is demonstrated, showing the exceptional result in two differently arranged LC cells. The findings highlight that simple molecules, like those in nature and living organisms, can shape intricate systems with significant implications for the accelerated progress of laser and display technologies, along with Li-Fi concepts.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"25 1","pages":"e11648"},"PeriodicalIF":29.4,"publicationDate":"2025-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145003271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional strategies rely on excessive chemical additives to accelerate the initial deprotonation step for efficient dehydrogenation. However, this approach is energy-consuming and compromises the intrinsic hydrogen storage density (53 g L-1) of formic acid. Here, we tackle this challenge by designing a floatable photothermal reaction platform featuring hedgehog-like Pd-nitride nanocones supported on carbon fiber sheets. Leveraging the structure-induced floating and superaerophobicity design, this platform enables instantaneous bubble detachment from reactive sites, facilitating local product removal and thereby propelling deprotonation without additives. Consequently, an exceptional H2 production rate of 478 mmol g-1 h-1 was achieved from pure formic acid, tripling the rate of the current top-performing catalytic materials. This strategy offers fresh perspectives into liquid hydrogen carrier dehydrogenation, enabling simultaneously high-rate hydrogen production and high hydrogen storage density.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"40 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145007118","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aging state MPEA (AG-MPEA) has a multi-scale heterostructure controlled by spinodal decomposition: (I) Bimodal-size structure; (II) Different component regions divided by coherent diffusion phase interfaces; (III) Uniformly distributed Cu-rich and Fe-rich particles in the matrix. The multi-scale heterostructure provides more diffusion phase interfaces and different flow stress regions. The coherent diffusion phase interface hinders the hard transfer of dislocations between different compositional regions, which shortens the free path of dislocation slip. In addition, when crossing from one region to another, dislocations repeatedly face slip congestion, causing the slip band to be filled with accumulated dislocations. Different compositional regions are highly effective in delaying the movement of dislocations, which benefits from their lattice strain and surrounding strain gradient. The enhanced hetero-deformation-induced strain hardening and the formation of microscopic strain bands stabilize plastic deformation and improve ductility.

In addition, an asymmetry of switching between N‐polar and M‐polar states is observed, which decreases as the film thickness reduces. Integrated differential phase contrast scanning transmission electron microscopy reveals an inhomogeneous distribution of defects between interfacial and bulk regions, as well as the pinning of ferroelectric domains near the interface during switching, which could account for the change of switching behaviors with thickness scaling.

In this study, biomass‐derived, amphibious, and erasable adhesives are fabricated by grafting 3‐aminobenzoic acid and 3‐aminobenzeneboronic acid onto epoxidized soybean oil (ESO), yielding ESO‐Am adhesives. These adhesives are dynamically cross‐linked with boroxines, hydrogen bonds, and hydrogen‐bonded hydrophobic nanodomains. ESO‐Am adhesives exhibit strong and durable adhesion to a wide range of substrates under dry conditions, with adhesion strengths comparable to those of commercial counterparts. Remarkably, they also demonstrate exceptional underwater adhesion without the need for post‐curing, achieving an adhesion strength of 5.2 MPa on iron, surpassing previously reported underwater adhesives. This outstanding performance is attributed to the synergistic effect of dynamic boroxine linkages and hydrogen‐bonded hydrophobic nanodomains, which enhance both cohesive strength and interfacial interactions. Importantly, the dynamic cross‐links allow for complete and on‐demand removal of the adhesive by simple ethanol rinsing. In addition, ESO‐Am adhesives are biocompatible, degradable in soil, and reusable, retaining 96% of their original adhesion strength after ten cycles of reuse. The combination of strong amphibious adhesion, full erasability, biodegradability, and reusability makes ESO‐Am adhesives highly promising for a wide range of sustainable and advanced applications.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"470 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2025-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145003074","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
