Porous soft bioelectronics is a new way to a library of imperceptible bioelectronic systems, that form natural interfaces with the human body. In this review, we provide an overview of the development and recent advances in multifunctional porous engineered soft bioelectronics, aiming to bridge the gap between living biotic and stiff abiotic systems.

Moving beneath the skin, we discuss implantable devices and systems enabled by porous bioelectronics with tissue-like compliance.

Here we report a novel self-assembled material exhibiting asynchronous fluorescence (FL) and structural color (SC), which enables multilevel optical sensing and encryption. Asynchronous FL and SC was achieved by chemically doping aggregation-induced emission luminogens (AIEgens) into one-dimensional block copolymer (BCP) photonic crystals (PCs) comprising alternating lamellae of two dielectric components. The AIEgen-derived FL of a nonswollen BCP PC with no visible SC was deactivated when it was swollen in a solvent, consequently exhibiting fully visible SC. The complementary FL and SC manipulation through reversible molecular (aggregation vs. separation) and structural (nonswollen vs. swollen) alteration aided in developing a multimode sensing display, which could detect temperature and/or nitroaromatic gas in FL mode as well as the pH of a solution in SC mode.

Regarding large segmental femoral defects in rabbits, a mechanically adaptive bioenergetic-active scaffold was customized and greatly enhanced the diaphysis stability and bone reconstruction, achieving bone bridging across the defects.

S-scheme photocatalysts have garnered extensive attention because of their distinct charge transfer mechanisms, which lead to their superior photocatalytic performances. Numerous materials based on quantum dots (QDs) have been fabricated and applied in S-scheme photocatalytic systems. However, a comprehensive analysis of current advancements in this field is lacking. To address this gap, this review summarizes the state-of-the-art progress of QDs-based S-scheme photocatalysts. First, the development of S-scheme heterojunctions and origin of QDs are concisely retrospected, followed by a discussion about the advantages of employing QDs to build S-scheme photocatalysts and the common strategies to synthesize QDs and QDs-based S-scheme photocatalysts. The photocatalytic performance and mechanisms of QDs-based S-scheme heterojunction materials are thoroughly discussed, highlighting the key roles of QDs and the S-scheme interfacial charge transfer process. To date, semiconductor QDs of various compositions (e.g., metal sulfides/oxides, graphitic carbon nitride, perovskites, and black phosphorus) have been explored as reduction or oxidation photocatalysts in S-scheme heterojunctions. Moreover, noble metal, Ti<sub>3</sub>C<sub>2</sub>, and carbon QDs have been used as cocatalysts for S-scheme photocatalysts. Finally, future directions for the further exploration of QDs-based S-scheme photocatalysts are proposed. This review is expected to stimulate further exploration and development of S-scheme photocatalysts, paving the way for potential breakthroughs and applications.</div></div>","PeriodicalId":387,"journal":{"name":"Materials Today","volume":"82 ","pages":"Pages 251-273"},"PeriodicalIF":21.1,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143378215","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 theoretical calculations combined with experimental characterization interprets the co-intercalation possibility of sodium titanate (NTO) and the relationship between oxygen vacancies and co-intercalation chemistry. The redistributed charge in short-range with weakened polarization effect and reduced Fermi level of the entire crystal make Na<sup>+</sup>-diglyme co-intercalation easier and more reversible. Particularly, the disordered “valve” interface significantly reduces diffusion energy barrier, lowers bulk impedance, and generates high-quality SEI film, therefore, the subzero-T working ability of NTO has been sufficiently improved. As expected, the constructed desolvation-free SIHCs exhibit superior temperature compatibility and extraordinary cycling stability, maintaining capacitance retention of 74 % after 20,000 cycles at −40 °C and cycling over 10,000 cycles with a capacitance retention of 78 % at −60 °C.

In this review, we first discuss several typical surface corrugations of graphene and 2D materials that are commonly observed on a substrate, including minor, standing, contacted and lying wrinkles, as well as wrinkle networks. We then introduce a criterion to ascertain the wrinkle-free state by equating the total compressive strain obtained from CTE mismatch to the sum of the strain released by the wrinkles and the residual strain, which can be deduced from the morphology of wrinkles and Raman spectroscopy, respectively. Based on this criterion, we review several notable endeavors in the synthesis of wrinkle-free graphene and finally answer the question of where the lost compressive strain goes.
