Silicon carbide (SiC) is a third-generation semiconductor material with a wide band gap and excellent high-temperature stability and is regarded as a good candidate for overcoming the high-temperature intolerance of traditional pressure sensors. Currently, there are few reviews on recent advances in the synthesis, characterization, sensing mechanisms, design methodology, fabrication processes, operation, and application issues of SiC-based pressure sensors used under extreme application conditions. This review explores the following key topics: (i) key properties and special attributes of SiC materials; (ii) synthesis of SiC materials and thin films for high-temperature pressure sensor applications and processing of SiC materials, including etching, ohmic contacts, and bonding; (iii) recent development of SiC piezoresistive pressure sensors, including those based on silicon-on-insulator and all-SiC designs; (iv) recently reported SiC capacitive pressure sensors, including both 3C-SiC-based and all-SiC designs; and (v) advances in SiC-based fiber-optic pressure sensors. Finally, we highlight the key challenges and future prospects of next-generation SiC-based high-temperature pressure sensors.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"55 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143876291","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}

The resulting PyTA-2,3-NA(OH)₂ HO-COF is more hydrophilic than the PyTA-2,6-NA(OH)₂ HO-COF, which can effectively enhance the sensitivity of the sensor toward basic ethylenediamine (EDA). The fabricated HO-COF nanofiber-based quartz crystal microbalance sensor exhibits a rapid sensing response and a distinguished selectivity toward EDA vapor, arising from the strong hydrogen bonding interactions with the NH₂ groups of EDA, as investigated by a wide variety of chemical analysis techniques and density functional theory calculations. The presence of exposed neighboring hydroxyl groups that face the same direction in the PyTA-2,3-NA(OH)₂ HO-COF and the NH₂ groups present in EDA exhibited efficient interactions. The PyTA-2,3-NA(OH)₂ nanofiber with neighboring hydroxyl groups exhibits 1.6 times higher sensitivity to 100 ppm (ppm) EDA than PyTA-2,6-NA(OH)₂ with hydroxyl groups in opposite directions, with a low limit of detection of 2.9 ppm. The PyTA-2,3-NA(OH)₂ nanofiber structure has abundant active neighboring hydroxyl groups facing the same direction, making them favorable active sites for binding EDA molecules through strong hydrogen bond interactions. The color of the HO-COF changed after exposure to EDA vapor, as investigated by colorimetric assessment and naked-eye detection. These HO-COF nanofibers exhibit remarkable selectivity for EDA in the presence of other interfering chemical vapors and show high stability with only a 6.4% drop in sensitivity after 6 months. The adsorption of EDA on PyTA-2,3-NA(OH)₂ nanofibers follows a pseudo-first-order kinetic model, with an adsorption rate about 8.0 times faster than PyTA-2,6-NA(OH)₂ nanofibers. The findings of this study highlight the potential use of COFs, particularly those nanofibers with close neighboring hydroxyl groups, as effective sensing materials for the selective detection of harmful EDA.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"42 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143876329","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}

The AzoCPT-Lips had a high encapsulation efficiency (95%), loading capacity (20%, by weight), and good storage stability. The AzoCPT was efficiently taken up by 4T1 tumor cells (100-fold higher than CPT) and readily converted into active CPT in the cytoplasm to exert 10-fold higher cytotoxicity than free CPT. More importantly, AzoCPT-Lips resulted in 5–20 times higher tumor distribution of active CPT than that of CPT solution or those in other tissues, which further led to more potent antitumor activity and lower toxicities in the 4T1 breast cancer xenograft. Such a cationic Azo tag represents an effective strategy for developing liposomal antitumor drugs with improved antitumor efficacy.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"14 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143876326","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}

While vacuum-based evaporation of Me-4PACz offers significant potential for large-scale PSC fabrication, its application is hindered by the poor wettability of the evaporated SAM, which adversely affects the device performance. In this work, an evaporated cuprous thiocyanate (CuSCN) film was employed to modify the evaporated Me-4PACz, which can improve the wettability, leading to enhanced coverage and uniformity of the perovskite film. In addition, the incorporation of CuSCN established an energy level gradient at the SAM–perovskite interface, facilitating efficient hole transport. Moreover, the CuSCN layer contributed to interface passivation, effectively reducing interface recombination losses. As a result, an efficiency of 21.62% for single-junction wide-bandgap PSCs (1.68 eV) was achieved. Additionally, the films fabricated by evaporation show good uniformity on a large-area substrate, laying a foundation for large-area PSCs.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"17 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143876294","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}

Zr-phenolic (Zr-PR) aerogels have been extensively studied due to their exceptional high-temperature resistance. However, the phase transformation of ZrO₂, the pyrolysis product of Zr-PR, caused the volume changes and internal stresses, greatly limiting the application of Zr-PR. In this work, a small amount of nano-Y₂O₃ particles was directly doped into the Zr-PR aerogel composites to form the nanoscale mosaic structure. This aerogel composite exhibited properties of low density (0.51 g/cm³) and low thermal conductivity (&lt;0.151 W/(m K)); moreover, it showed a significant improvement in oxidative ablation resistance with a 33% reduction in the linear ablation rate. The research indicated that the doping of nano-Y₂O₃ effectively addressed the adverse effects associated with ZrO₂ phase transformation by in situ rapidly forming (&lt;60s) the dense yttria-stabilized zirconia (YSZ) thermal barrier layer on the ablation surface, which significantly delayed the thermal-oxidative ablation of the composites. Additionally, the pyrolytic carbon (PyC) on the ablation surface can form abundant multilayered graphene structures due to the catalytic graphitization effect produced by the solid-solution reaction of YSZ, which further enhanced the oxidation resistance. This work provides a simple and efficient approach to improve the ablation performance of Zr-PR aerogel composites, broadening their application in extreme thermal environments.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"43 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143876299","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}

In this study, we present a temperature-responsive composite material composed of poly(<i>N</i>-isopropylacrylamide) (PNIPAAm) and a polyurethane (PU) sponge loaded with graphene oxide (PU@GO), referred to as PGPC. This composite exhibits switchable MA behavior below and above its lower critical solution temperature (LCST). Below LCST at 20 °C, the material shows minimal MA effectiveness (reflection loss &lt; −10 dB), while at 50 °C, the reflection loss significantly improves to −42 dB with a bandwidth of 3.45 GHz. Structural characterization, both in situ and ex situ, reveals that this tunable behavior is driven by the reversible dissociation and reconstruction of a three-dimensional (3D) graphene network, triggered by the thermally induced movement of PNIPAAm molecular chains grafted onto the graphene sheets. Furthermore, the incorporation of PU enhances the composite’s mechanical properties. The ability of PGPC to combine switchable MA performance with mechanical robustness makes it a promising candidate for intelligent, adaptive electromagnetic interference protection material, addressing current technological needs in dynamic environments.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"29 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143875910","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}

The EG-OFET is operated by applying gate voltages, enabling the monitoring of organic reactions on the extended-gate electrode through changes in transistor characteristics. Leveraging its amplification ability, the EG-OFET enables the sensitive detection of slight differences in product properties accompanied by variations in the charge and/or dipole moment of the SAM caused by chemical reactions at the interface.

In the absence of an HTL, CsPbBr₃ exhibited dominant hole dynamics, which were mitigated by the introduction of Spiro-OMeTAD and P3HT, with the latter showing superior hole extraction efficiency. In this follow-up study, we extend our analysis to electron transport layers (ETLs) and the full ETL/perovskite/HTL structure, and investigate modulation of charge separation at interfaces. Our results show that TiO₂, a widely used ETL, enhances electron extraction but still exhibits recombination due to interfacial states. Li and Pt doping further improve charge separation, with Pt-doped TiO₂ demonstrating the most significant reduction in recombination and the longest charge carrier lifetimes. When combined with HTLs, the choice of HTL significantly impacts charge extraction: P3HT facilitates more efficient hole removal than Spiro-OMeTAD. The most effective configuration for charge separation and suppression of residual charge carriers was achieved with Pt-doped TiO₂ as the ETL and P3HT as the HTL. These findings provide a comprehensive understanding of charge carrier transport in inorganic perovskite solar cells, demonstrating the importance of both ETL and HTL selection for optimizing photovoltaic performance.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"35 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143875908","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}
