Based on this, this review provides a comprehensive overview of the latest advancements in the application of carbon materials in ASSBs. It first details the issues affecting the performance of ASSBs, followed by an introduction to the various categories of carbon materials with distinct characteristics that can be used in ASSBs, including graphene, carbon nanotubes, carbon dots, and carbon fibers. It then delves into strategies for applying carbon materials to the electrolyte, cathode, and anode of ASSBs, offering solutions to address key challenges. Finally, the paper outlines the key challenges and future prospects, providing guidance and insights for the rational design and selection of carbon materials for next-generation ASSBs.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"49 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145195197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They hold high potential for the use as classical and quantum emitters in fiber-based photonics that operate at telecommunication wavelengths. Up to now, the insolubility of 2D PbX NPLs in water and other polar solvents has been a challenge that complicates their post-synthesic processing, e.g. into future functional nanocomposites. Here, we describe a phase transfer protocol from hexane to water using 11-mercaptoundecanoic acid (MUA), which yields aqueous phase 2D PbS, PbSe, and PbTe NPLs with preserved shape, crystallinity and NIR PL (e.g. PbS: 724 nm, PbSe: 1023 nm and PbTe: 1184 nm). Water-soluble 2D PbSe shows efficient emission (up to 13 % PL quantum yield at 1023 nm), thereby retaining 65 % of the initial quantum yield and making it highly interesting as aqueous NIR light source. By using X-ray photoelectron spectroscopy (XPS) and nuclear magnetic resonance (NMR), we follow the phase transfer on a molecular level and find two binding motifs of MUA to the PbX surfaces: X-type bound thiolate and L-type bound thiol. Our results shine new light on mercaptocarboxylic acid based nanomaterial phase transfer and respresent a cruical step for incorporating NIR-emissive 2D PbX into (fiber) optics.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"72 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145195202","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Carbon nitride (C3N4; Egap = 2.7 eV) is an attractive representative, as it is a non-toxic material containing abundant elements. Future technologies, e.g., in optical computing, demand semiconductors in which one can reversibly change key characteristics such as Egap by preferably simple methods (temperature, pressure, presence of ions) and reversibly. The current paper demonstrates that carbon nitride protonated by hydrofluoric acid (HF) fulfills these requirements. The protonation process is studied in detail, and unlike the reaction with hydrochloric acid, the reaction with HF is topotactic. The attachment of the protons to the nitrogen atoms induces a decrease in the interlayer spacing. In contrast, the intralayer spacing is increased due to the incorporation of 𝜋-bonded fluoride ions in the voids of the carbon nitride planes. These effects together lead to a pronounced structure-property correlation and a notable blue shift of Egap to almost 3eV. Pristine carbon nitride can be restored by simple thermal treatment. Even more interestingly, a third and new state can be reached by applying pressure. Thus, one can switch reversibly between these three states by using HF, temperature, and pressure.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"99 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145195367","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Winter","doi":"10.1039/d5nr01695a","DOIUrl":"https://doi.org/10.1039/d5nr01695a","url":null,"abstract":"This contribution investigates the role of the metal-metal bond in paddle-wheel complexes for molecular conductance. To these ends, we compare two pairs of Mo and Rh paddle-wheel complexes M2(LN)4 and M2(LSMe)4 (M = Rh, Mo), each with four lateral 4-pyridyl- (LN-) or 4-(methylthio)- (LSMe-) functionalized benzamidinate ligands mutually disposed at 90° angles. These complexes represent bond orders of 4 (Mo) and 1 (Rh), while offering metal-based highest occupied frontier orbitals of the same δ symmetry. The structural features of the complexes were established by X-ray diffraction on single crystals. Molecular conductance measurements were performed with the aid of a scanning-tunnelling microscopy break-junction setup and revealed that the Mo complexes surpass their Rh congeners. Decoration of the paddle-wheel complexes with four laterally disposed anchor groups results in four different possible modes of molecule attachment to the Au electrodes with two, three or even four anchoring points. The conductances of possible junction geometries were assessed quantum chemically with the DFT+Σ approach using Au slab electrodes. Calculated variations by about one order of magnitude for the different anchoring geometries can explain the rather broad conductance distributions observed in our experiments. Further transport calculations considered two-point molecule attachment to sharp or blunt nanoelectrodes for mutual cis and trans dispositions of the anchor groups. Our computational results indicate that the better performance of the Mo complexes originates from superior conjugation between the Mo2 δ-binding and the ligand π orbitals as compared to the Rh2 δ* orbital, rather than from the larger metal-metal bond order. Upon increasing the bias voltage, we observed a new conductance feature associated with a nearly 100 times higher G value, which we ascribe tentatively to oxidation of the molecule inside the junction","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"6 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145188967","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work presents a wetting-gradient bilayer structured solar-driven hydrogel evaporator (B-CPVA) featuring a relatively hydrophobic upper layer (carbon nanotubes-polyvinyl alcohol B-CPVA) for efficient broadband solar absorption and high photothermal conversion, combined with a hydrophilic bottom layer (PVA) to facilitate rapid water transport.
