However, current fiber sensors are strictly limited to either infrared evanescent wave or temperature sensing, primarily due to the absence of suitable fiber sensing media. Here, a high-performance infrared evanescent wave-temperature dual sensor based on single Ge[Formula: see text]Se 3 Te[Formula: see text] chalcogenide glass fiber is developed. The obtained fiber exhibits a high Seebeck coefficient of 1410[Formula: see text] [Formula: see text]V/K, a precise temperature resolution of 0.03[Formula: see text]K, a fast response time of 6[Formula: see text]s and superior infrared evanescent wave sensing performance. Furthermore, the fibers can be integrated into a textile to detect temperature distribution and simultaneously detect organic substances such as ethanol and urea.

Nowadays, the challenge for ECE refrigeration devices is mainly due to the lack of high-performance ECE materials.

However, the limited availability of ultrasonic resources in nature restricts its practical application. Our proposed peak flow kinetic energy piezocatalytic strategy, based on a “waterfall flow” model, aims to simulate the piezocatalytic degradation of pollutants in nature. This innovative strategy can enhance degradation efficiency by adjusting the flow rate and drop height. When 140[Formula: see text]mL of rhodamine B (RhB) dye solution flows at a rate of 1000[Formula: see text]mL/min from a height of 48[Formula: see text]cm and impacts a 3 cm diameter BaTiO 3 nanowires/PVDF piezoelectric composite film, a degradation rate of 90% can be achieved within 120[Formula: see text]min. This rapid degradation is primarily attributed to the efficient conversion of kinetic energy into impact force as the water falls, which triggers the generation of piezopotential in the composite film. This, in turn, drives the separation and transmission of electron–hole pairs, leading to the promotion of reactive oxygen species (ROS) generation and facilitating fast organic dye degradation. The pulsating nature of the impact force ensures a continuous generation of ROS. This approach is poised to advance piezocatalysis for the degradation of organic dyes in natural environments and presents a novel method for wastewater treatment.","PeriodicalId":505951,"journal":{"name":"Journal of Advanced Dielectrics","volume":"15 03","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147914998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The morphology results reveal that the microsphere-shaped ZnO is dispersed on the surface of the blocky-like BiFeO 3 , with intimate contact between the two phases. It has been found that the maximum piezocatalytic activity could be achieved at BiFeO 3 /ZnO molar ratio of 5:1, with a degradation rate up to 92% for RhB. Compared with pure BiFeO 3 and ZnO, the composites have superior piezocatalytic degradation performance. The reason for the enhanced piezocatalytic dye degradation rate may be that the BiFeO 3 /ZnO composites effectively separate the positive and negative charges to reduce the recombination of positive and negative charges. These active species, such as superoxide radicals ([Formula: see text]) in the process of piezocatalytic, are proved on the active species capture experiments. The BiFeO 3 /ZnO composites have good piezocatalytic degradation performance, which provides an option for collecting vibration energy to degradation dye wastewater in the future.","PeriodicalId":505951,"journal":{"name":"Journal of Advanced Dielectrics","volume":"15 02","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147901343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
