Biodegradable supercapacitors can safely resorb after completing their function, eliminating secondary surgical removal and reducing long‐term foreign‐body complications, unlike conventional batteries. This review comprehensively discusses recent advances in degradable supercapacitors, focusing on biocompatible polymers, bioresorbable electrodes, separators, electrolytes, and current collectors. This review critically evaluates the electrochemical performance of biodegradable supercapacitors under physiological conditions, including capacitance retention, cycling stability, and degradation behaviour. Current challenges, such as limited energy density, mechanical instability, precise bioresorption kinetics, and scalability, are discussed. This study addresses key regulatory and safety considerations, including biocompatibility, toxicity, immunogenicity, and pathway approval. Further, outlines strategic future directions: bio‐derived carbon, biologically synthesized conductors, self‐healing hydrogel electrolytes, stimulus‐responsive programmable degradation, and energy‐harvesting integration. Emerging frontiers at the intersection of bioelectronics, neuromorphic computing, and living devices, and advocates for standardized benchmarking and circular‐economy integration.

These microspheres serve as functional fillers within liquid metal (LM) matrix to create magnetic liquid metal (MLM) with magnetism and enhanced conductivity. We focus on the physical mechanism of density matching, achieved by using high‐density W to align the density of Co‐W cores with that of liquid Ag. This strategy effectively suppresses the upward buoyancy of cores during spheroidization. Furthermore, finite element simulations elucidate the critical role of the marangoni effect in promoting the formation of this core‐shell structure. Experimental results verify that density matching significantly improves the encapsulation quality of Ag shells, thereby endowing the fillers with exceptional resistance against LM corrosion. Finally, the versatility of this MLM is validated across the magnetically actuated liquid‐metal soft robot, refreshable liquid‐metal blackboard, self‐healing circuits, and magnetic liquid‐metal strain sensor.

A prerequisite for designing MOFs with optimal thermal conductivities is developing a profound understanding of the underlying atomistic mechanisms. This is at the heart of the present publication, where we first show that the common approach of describing heat conduction in crystalline insulators as a particle-like propagation of phonons (as vibrational energy quanta) is insufficient. This is the consequence of strong inter-band couplings between the densely lying phonon bands in the highly complex materials considered here (MOF-5 and HKUST-1). When accounting for that through suitable physical models in combination with highly accurate machine-learned potentials, a quantitative agreement with experimental single-crystal data becomes possible. Interestingly, the phonons dominating particle-like transport are primarily (acoustic) modes at very low frequencies (up to ∼1.5 THz), while inter-band transitions also occur at much higher frequencies. This can be explained by the sharp drop of phonon lifetimes with frequency, which diminishes particle-like transport but promotes inter-band coupling. Our analysis not only rationalizes the differences in thermal conductivities between MOF-5 and HKUST-1, but also lays the foundations for developing a phonon-based understanding of thermal transport processes in MOFs.","PeriodicalId":228,"journal":{"name":"Small","volume":" ","pages":"e75959"},"PeriodicalIF":11.8,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149190118","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we introduce a patterning strategy suitable for solution‑processable organic semiconductors, enabling high‑fidelity OECT arrays with suppressed leakage and off‑state currents, on/off ratios up to 10 7 , and good device‑to‑device uniformity. Leveraging these patterned OECTs, we demonstrate the integration of logic circuits, including complementary inverters as well as NAND and NOR gates, exhibiting high voltage gain (up to 203 V/V), large noise margins (92.17%) and stable operation at low supply voltages. Benefiting from the patterning approach and the AlO x ‐induced suppression of off‐state current, the static power consumption of the inverter is reduced by approximately 90%. Beyond digital logic, we further show that these devices emulate key synaptic functions such as short‐term plasticity and enable reservoir computing tasks, defining a manufacturable platform for integrated bioelectronic circuitry and neuromorphic architectures. This patterning strategy therefore provides a general route toward high‐density biointerfaces and next‐generation brain–computer interfaces.","PeriodicalId":228,"journal":{"name":"Small","volume":"53 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149172954","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we report two central findings. First, focused 785 nm continuous-wave laser irradiation of gold nanorod-TiO2 core-shell nanoparticles (AuNR@TiO2) drives amorphous TiO2 nanoshells through the complete amorphous → anatase → rutile phase sequence within one second. Achieving such extreme local temperatures through plasmonic photothermal heating is exceptional. The transformations are unambiguously confirmed by in situ Raman spectroscopy and ex situ selected-area electron diffraction. Wavelength-selective crystallization reveals that plasmonic absorption of AuNR cores leads to the phase transition. Second, nanoparticle assembly geometry is a decisive design parameter: isolated particles on silicon nitride membrane grids transform predominantly to anatase, whereas dense multilayer assemblies on glass substrates produce rutile under identical conditions. Heat-transfer simulations reveal that overlapping thermal fields in closely packed assemblies elevate local temperatures far beyond those achievable by single-particle heating-a collective thermal accumulation effect that determines the final crystalline phase. These findings establish plasmonic nanoheating as a viable route for spatially selective phase engineering of oxide nanomaterials and identify nanoparticle assembly as a tunable handle for controlling nanoscale crystallinity.","PeriodicalId":228,"journal":{"name":"Small","volume":" ","pages":"e76316"},"PeriodicalIF":11.8,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149190443","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
