The sensitivity and pressure-sensing range of current humanoid tactile sensors have performed significant advancements. However, the temperature susceptibility of conductive materials and the rapid saturation of conductive contact sites in soft polymeric materials bring about challenges for these sensors, including environmental interference and a narrow linear sensing range. These issues lead to the inconsistencies between the sensing signal and contact behavior, which eventually deteriorates both the accuracy and reliability. Here, we propose a flexible piezoresistive pressure sensor with minimized response to temperature variation but extended linear sensing range. The sensor utilizes a novel hybrid conductive material elaborated to exhibit zero temperature resistance coefficient by combining the materials with the opposite temperature coefficients, which allows for a reliable operation ranging from 20 to 70 ℃ with temperature variation induced fluctuation free. Additionally, the sensor provides a biomimetic polymer microstructure with multilevel cone-dome structural feature, which results in an ultra-wide linear pressure-sensing range from 0 up to 200 kPa. In addition, based on the simple and scalable fabrication process, a high-density sensor array (16×16) is produced to outline the spatial pressure distributions accurately even under the external temperature interferences and successfully discern the texture of the contact object.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"17 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143920051","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}

However, due to the uncontrollable donor/acceptor (D/A) arrangement in thick‐film condition, the restricted exciton splitting and severe carrier traps significantly impede the photovoltaic performance and operability. Herein, combined with layer‐by‐layer deposition technology, a twisted 3D star‐shaped trimer (BTT‐Out) is synthesized to develop a trimer‐induced pre‐swelling (TIP) strategy, where the BTT‐Out is incorporated into the buried D18 donor layer to enable the fabrication of thick‐film OSCs. The integrated approach characterizations reveal that the exceptional configuration and spontaneous self‐organization behavior of BTT‐Out trimer could pre‐swell the D18 network to facilitate the acceptor's infiltration and accelerate the formation of D/A interfaces. This enhancement triggers the elevated polarons formation with amplified hole‐transfer kinetics, which is essential for the augmented exciton splitting efficiency. Furthermore, the regulated swelling process can initiate the favorable self‐assembly of L8‐BO acceptors, which would ameliorate carrier transport channels and mitigate carrier traps. As a result, the TIP‐modified thin‐film OSC devices achieve the champion performance of 20.3% (thin‐film) and 18.8% (thick‐film) with upgraded stability, among one of the highest performances reported of thick‐film OSCs.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"53 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143920203","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}

Therefore, we explored a novel approach using green-engineered materials that we developed an injectable hydrogel (CPE) based on polyphenol-borate ester bonds by functionalizing chitosan. These biopolymer composites exhibit excellent biocompatibility, mitigating drug-related toxicities. Our hydrogel delivery system concurrently administers cabazitaxel and imiquimod (R837) for localized chemotherapy and immunotherapy. Cabazitaxel-mediated chemotherapy induces immunogenic cell death (ICD) of tumor cells, releasing tumor-associated antigens (TAAs), that promote dendritic cell maturation and cytotoxic T lymphocyte (CTL) infiltration. The in situ release of the TLR7 agonist R837 further stimulates the immune system, inducing an effective and sustained antitumor immune response tailored to CRPC. In summary, by establishing an in situ drug reservoir, we effectively inhibited tumor invasion and progression and induced a durable immune response, offering a new perspective on localized immunotherapy for the clinical treatment of CRPC.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"31 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143920312","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}

After aging treatment, the microstructure is slightly coarsened, together with the precipitation of nano-sized D0<sub>3</sub>−Mg<sub>3</sub>Al particles, as well as the dissolution and the mergence of α-Mg phases. Negligible strength and ductility anisotropies are found for the as-deposited alloy. Significant strength increment is achieved via aging treatment, and the ultimate strength increases by ∼20% (∼34 MPa), reaching 200±1 MPa. Both as-deposited and aged alloys show acceptable uniform elongation, with a transgranular fracture mode. Precipitation strengthening enabled by nano-sized D0<sub>3</sub>−Mg<sub>3</sub>Al precipitates is primarily responsible for the strength increment mediated by aging treatment. Grain refinement strengthening and solid solution strengthening provide additional contributions to the improved strength.

The grading and charge layers as well as the multiplication regions of the APDs were well resolved electrically in this study. The light-induced capacitance response in the multiplication region was found to differ by 2–4 times in the two devices, signifying a much higher photocarrier concentration under the same excitation intensity. Additionally, a sharp gradient of capacitance was observed along the core regions, which directly reflects the pronounced drifting of photocarriers in the strong built-in electric field.

Recent advances in machine learning potentials have led to foundation atomistic models, such as MACE-MP-0, that accurately predict equilibrium structures but struggle with phonon properties of MOFs. In this work, we developed a workflow for computing phonons in MOFs within the quasi-harmonic approximation with a fine-tuned MACE model, MACE-MP-MOF0. The model was trained on a curated dataset of 127 representative and diverse MOFs. The fine-tuned MACE-MP-MOF0 improves the accuracy of phonon density of states and corrects the imaginary phonon modes of MACE-MP-0, enabling high-throughput phonon calculations with state-of-the-art precision.
