Notably, the development of the emerging field of piezoelectric sensors can unveil flexible e-skins. Herein, a new type of e-skin based on piezoelectric porous polyvinylidene fluoride (PVDF) nanospheres for robotic perception has been reported. We have employed an elegant method based on the thermodynamics of polymer solutions to induce porosity in PVDF nanospheres. By adding a defined amount of water, chosen from the ternary phase diagram of PVDF/water/dimethylformamide (DMF), porous PVDF nanospheres have been synthesized. Piezoelectric measurements along with finite element method (FEM) simulations have confirmed that porous nanospheres generate a higher output voltage compared to dense ones. It is realized that the fabricated e-skin using porous PVDF nanospheres is thin, flexible, and durable. Besides, it can efficiently distinguish finger pressing. At the final stage, the e-skin integrated with electronic circuits and a microcontroller has been able to successfully control the grasp action of a robotic hand. Consequently, it can be envisioned that the proposed e-skin has great potential for future applications in robotics and human–robot interactions.</p>","PeriodicalId":84,"journal":{"name":"Journal of Materials Chemistry C","volume":" 40","pages":" 20742-20749"},"PeriodicalIF":5.1,"publicationDate":"2025-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145315631","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}

Hence, the 4f–5d hybridization is expected to significantly influence the electrical transport properties. In this study, these <em>RE</em>Os were found to show metallic conduction with gradually varied carrier polarity, where TbO was an n-type metal, DyO was a partially compensated n-type metal, and ErO was a partially compensated p-type metal. This variable carrier polarity is probably due to the degree of 4f–5d hybridization depending on each <em>RE</em> ion. The anomalous Hall effect possessed a larger remanence and coercive field than those of the magnetization below each Curie temperature. Intriguingly, ErO showed unusual clockwise hysteresis loops of the anomalous Hall effect with a superficially positive anomalous Hall coefficient, in contrast with usual anticlockwise hysteresis loops of the positive anomalous Hall effect in TbO and DyO. This unusual behavior of ErO is likely due to multiple anomalous Hall effects or a superposed semimetallic ordinary Hall effect. The simple rocksalt structure, strong spin–orbit interaction, and various carrier polarities as well as anomalous Hall effect would be beneficial to develop spintronic heterostructures.</p>","PeriodicalId":84,"journal":{"name":"Journal of Materials Chemistry C","volume":" 40","pages":" 20728-20734"},"PeriodicalIF":5.1,"publicationDate":"2025-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145315629","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}

Besides, the adsorption mechanism is explained. The adsorption behaviour is more relevant to the terminal atoms on the surface, compared with the material itself; the intrinsic electric fields caused by the electrostatic potential difference between the two ends of asymmetric Janus structures can influence the charge transfer behaviour of gas molecules, which is promising for surface engineering of MXenes to meet specific demands.</p>","PeriodicalId":84,"journal":{"name":"Journal of Materials Chemistry C","volume":" 40","pages":" 20699-20714"},"PeriodicalIF":5.1,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145315628","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}
