Artificial diamonds have emerged as a cornerstone material in advanced technology due to their exceptional physical, chemical, and optical properties. The broad bandgap, chemical inertness, and superior thermal conductivity of diamonds are utilized by these sensors to provide excellent resistance to extreme temperatures and severe environments. The sensitivity of the sensor to various gases is enhanced by hydrogen-terminated diamond surfaces, which enable p-type surface conductivity through charge transfer interactions. Advances in chemical vapor deposition (CVD) techniques have increased the availability of high-quality diamond films for microfabricated sensor systems. Applications of diamond in environmental monitoring and industrial safety, with a focus on detecting dangerous gases including CO, NOx, and volatile organic compounds (VOC), have been the main focus of the review. This study provides a comprehensive recent report of diamond-based gas sensors, emphasizing advancements as well as possible directions for the future. This review is really helpful for researchers looking to employ artificial diamonds in extreme conditions for the detection of gases to develop solutions in a quickly changing technological context.&#xD.","PeriodicalId":19035,"journal":{"name":"Nanotechnology","volume":" ","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144718221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper innovatively proposes anin-situvibration monitoring method, designing a low-frequencyin-situdetection system based on triboelectric nanogenerator technology. The system not only enables efficient low-frequency signal detection in complex underwater environments but also, by incorporating machine learning algorithms, identifies different signal sources, achieving accurate distinction of intrinsic signals.

Ferroptosis is a form of programmed cell death that relies on iron and is non-apoptotic, triggered by the inhibition of the cellular antioxidant system. Photodynamic therapy (PDT) employs photosensitizers to produce reactive oxygen species (ROS), increasing oxidative stress in tumor cells. When combined with ferroptosis, PDT can work synergistically to regulate intracellular redox balance. In this study, we designed engineered nano-erythrocyte membranes for targeted delivery of Chlorin e6 (Ce6) and cisplatin (DDP) to enhance breast cancer treatment. By using mild ultrasound, Ce6 and DDP were co-loaded onto the nano-erythrocyte membranes, combining ferroptosis inducers and photosensitizers to combat breast cancer. To improve targeting capability towards breast cancer, RGD cyclic peptides were modified onto the nano-erythrocyte membranes through a thiol-maleimide coupling reaction. The RGD-modified nano-erythrocyte membranes co-loaded with Ce6 and DDP not only inherited the good stability and significant biocompatibility of red blood cell membranes but also promoted the uptake by breast cancer cells, effectively inducing ferroptosis in these cells. In conclusion, this multifunctional 'natural' nanodrug delivery system provides an effective and safe method for PDT combined with ferroptosis for breast cancer treatment.","PeriodicalId":19035,"journal":{"name":"Nanotechnology","volume":"36 30","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144691047","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, conventional unit catalysts often fall short of practical requirements, primarily due to their limited efficiency in photoinduced electron-hole transfer and the scarcity of active sites. In this work, three-dimensional porous material pg-C3N4 was synthesized utilizing the hard template method, employing dendritic mesoporous silica as the templating agent. And the nanoparticles of BiVO4/pg-C3N4 direct Z-heterojunction composite (BCN) were successfully constructed by using pg-C3N4 as growth template and BiVO4 in situ directed growth. The heterogeneous surface morphology of pg-C3N4 markedly enhances its capacity for visible light absorption and increases the availability of catalytic active sites. BCN demonstrates the ability to degrade 98% of Rhodamine B (RhB) under simulated solar irradiation within 120 min and effectively inactivates 2×107 cfu mL-1 of E. coli under similar conditions within 60 min. Notably, after five cycles of use, the structural integrity and functional properties of the material remain largely unaltered. The superior photocatalytic degradation and photodynamic sterilization performance of BCN can be primarily attributed to its narrower band gap width of 2.34 eV, reduced electrochemical impedance, and enhanced separation and transfer rate of photogenerated carriers. Collectively, these properties facilitate the effective degradation of organic pollutants and the robust inactivation of bacteria by BCN under visible light irradiation. The successful implementation of this research offers a theoretical foundation and experimental insights for the future development of advanced Z-type photocatalysts.&#xD.","PeriodicalId":19035,"journal":{"name":"Nanotechnology","volume":" ","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144699105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their implementation demands ultra-thin sacrificial Si3N4 layers and higher lateral-high-aspect-ratio (LHAR) trench structures compared to 3D NAND flash memory. In this study, 20 nm-thick multilayer LHAR trench structures with aspect ratio up to 30 were successfully fabricated via a combined dry and wet etching approach applied to SiO2-Si3N4-SiO2 multilayer stacks. Hafnium dioxide (HfO₂) thin films were subsequently deposited within these confined geometries and on planar silicon surfaces using atomic layer deposition (ALD). By systematically optimizing key process parameters: precursor pulse time and purge duration-optimal conditions for uniform and conformal film growth were established. The comprehensive deposition behavior of HfO₂ films in different geometric structures has been qualitatively analyzed using the molecular diffusion theory and the surface adsorption kinetics model. Resulting HfO₂ films exhibited predominantly amorphous structure, ultra-low surface roughness, and excellent electrical properties.

The heterostructure is fabricated on a flexible polyethylene terephthalate substrate. Comprehensive electrical and optoelectronic characterizations are conducted under various environmental conditions, with a focus on photocurrent response and the photovoltaic effect. The device shows a broadband photoresponse from 405 to 900 nm, reaching its best performance at 880 nm, where it delivers a peak responsivity of 0.07 mA/W, a specific detectivity of 2.3 × 107 Jones and rise/decay constants of 1.6 s / 1.5 s, measured under 405 nm illumination at an incident power of 0.19 mW (there is also a long time tail of 23 s, attributed to trap-assisted processes). The long-wavelength cut-off (~ 880 nm) corresponds to an indirect bandgap of 1.4 ± 0.1 eV for the nanotubes. Under 520 nm illumination the heterostructure generates an open circuit photovoltage of ~ 15 mV and a short-circuit photocurrent of ~ 0.08 nA, confirming the presence of a photovoltaic effect. Illumination at 405 nm reveals a photocurrent response that is sensitive to changes in environmental pressure.
