Artificial freshwater generation (AFG) through the efficient conversion of nonconventional water resources (NCWR, e.g., seawater, wastewater, and atmospheric water) offers a promising solution. Photoresponsive hydrogels are particularly attractive, harnessing solar irradiation to convert NCWR into freshwater while avoiding the high energy consumption of conventional technologies including reverse osmosis and thermal distillation. However, systematic reviews on the precise customization of hydrogels for solar-driven AFG remain scarce. This review presents recent advances in hydrogels for solar-driven AFG. We first examine the concept, structural features, and design orientations of hydrogels for AFG, followed by a detailed discussion of optimization strategies across seawater desalination, wastewater treatment, and atmospheric water harvesting. Finally, we present a forward-looking perspective on critical challenges, materials innovation, mechanistic insights, technology development, and application expansion, aiming to provide a comprehensive reference for researchers in this field.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"8 11","pages":"3086–3107"},"PeriodicalIF":8.6,"publicationDate":"2026-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149305641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Designing dual-modal agents for computed tomography (CT) imaging and radiotherapy sensitization remains a great challenge in tumor therapy. In this study, we designed and synthesized bismuth-based nanomaterials (Bi2Se3-TPP, TPP refers to triphenylphosphonium) with mitochondria-preferential accumulation and favorable CT imaging performance and prominent glutathione peroxidase (GPx)-like catalytic activity. The obtained Bi2Se3-TPP can efficiently catalyze the reaction between H2O2 and glutathione (GSH), which induces intracellular GSH depletion and disrupts cellular antioxidant defense. Compared to Bi2Se3-PEG, Bi2Se3-TPP exhibited superior radiosensitization efficiency due to its mitochondrial targeting capability and impaired cellular reactive oxygen species (ROS)-scavenging ability, which facilitates ROS accumulation upon irradiation enhanced ROS generation capacity. In vivo studies demonstrated that Bi2Se3-TPP possessed good biocompatibility, achieving a tumor suppression rate of up to 82.6% in the synergistic treatment group, indicating significant potential for tumor diagnosis and therapy.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"8 11","pages":"3276–3284"},"PeriodicalIF":8.6,"publicationDate":"2026-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149305721","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we report a physics-informed ‘artificial intelligence-driven two-dimensional molecular electronics spectroscopy’ (AI-2DMES) framework that enables the chiral discrimination of isomeric NPs at atomic resolution. The method succeeds in the sensitive and specific identification of three enantiomeric, one diastereomeric, and two constitutional isomer pairs via pre-computed transmission and conductance signals. To mimic experimental conductance variability, we introduce conductance-distribution features derived from density functional parameterized tight-binding molecular dynamics (DFTB-MD), incorporating thermal fluctuations, multi-orientation molecular contributions, and signal broadening into the AI training framework. Logistic regression achieves 100% binary classification accuracy across all six isomeric pairs and 98% multi-class accuracy across 10 NPs. These results demonstrate that AI-2DMES encodes sufficient stereochemical information for isomer differentiation and could be a powerful and general platform for chiral sensing.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"8 11","pages":"3144–3153"},"PeriodicalIF":8.6,"publicationDate":"2026-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149305712","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Owing to their high TC, their persistent spin order holds potential for a myriad of nanodevice applications both at and beyond room temperature. While the applications of thin films of these metallic two-dimensional ferromagnets have been explored in depth, use of their nanoparticles as catalysts for applications in green chemistry remains an untapped territory. Here, recent experimental investigations providing insights into the catalytic behavior of FexGeTe2 are discussed. Furthermore, employing in operando synchrotron-based X-ray radiation techniques in order to detect spectroscopic fingerprints of magnetic ordering in nanoparticles of FexGeTe2 is also proposed as a unique tool to gain fundamental insights into the role of their spin polarization in the catalytic process. This perspective is expected to endorse future research on the use of FexGeTe2 as magneto-catalysts for green chemistry.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"8 11","pages":"3018–3023"},"PeriodicalIF":8.6,"publicationDate":"2026-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149305960","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review focuses on the design, functionality, and catalytic applications of MXene-based composites. It begins with a brief introduction to the chemical and crystal structures of MAX phases and MXenes, followed by an overview of representative MXene-based composites, including 0D–2D, 2D–2D, and 3D–2D systems. The article then discusses their applications in heterogeneous catalysis, photocatalysis, biocatalysis, and electrocatalysis.

A tactile perceptual system (TPS) is proposed by integrating the RPS with a chitosan-gated oxide ionotronic neuromorphic transistor. Benefiting from the strong proton relaxation effects of the chitosan-based electrolyte, the neuromorphic transistor can effectively process electrical signals generated from the RPS. The TPS can emulate various synaptic behaviors under mechanical stimuli. As a proof of concept, it demonstrates Braille code recognition. Furthermore, the TPS enables touch intention recognition through machine learning, demonstrating a high recognition accuracy of ∼99.2%.

However, their highly conjugated and rigid structures greatly limit their regulation and processability. To address this, we explored a water beetle-like discotic liquid crystal molecule (HBC-AZO) with asymmetric photo-responsive flexible side chains, thereby improving its self-assembly tunability. Different post-treatment methods were employed to regulate the supramolecular assemblies of HBC-AZO on single-layer graphene substrates. The results showed that HBC-AZO exhibited homeotropic alignment after thermal annealing and inclined planar or disordered alignment under solvent-vapor annealing assisted by 455 or 365 nm light. These three distinct assembly states markedly modulated the charge-transport performance and transport pathway, which were further used to construct a proof-of-concept logic switch for directional charge-transport control.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"8 11","pages":"3162–3170"},"PeriodicalIF":8.6,"publicationDate":"2026-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149305637","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this challenge, we employed a bond-level dipole moment engineering strategy to stabilize lattice oxygen in Al-doped Cu2O. The oxophilic Al dopant enables a dual-locking mechanism through direct Al–O anchoring and enhanced neighboring Cu–O interactions by increasing the dipole moment. DFT calculations show that Al incorporation lowers antibonding orbital occupancy in Cu+ 3d–O 2p hybridized states, thereby suppressing lattice oxygen leaching. As a result, Al-Cu2O delivers a C2H4 Faradaic efficiency of 37.0%, compared with 20.5% for pristine Cu2O, and maintains stable operation for 50 h. This work supports bond-level dipole moment as a theoretical descriptor for catalyst stability and provides insights into stabilizing oxygen-containing electrocatalysts.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"8 11","pages":"3251–3260"},"PeriodicalIF":8.6,"publicationDate":"2026-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149305699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
