The study aimed to replace traditional plastic packaging methods and avoid aging issues by fabricating a novel multilayer laminated Cu coil/CaO–LiO–BO–SiO glass-ceramic structure. The analysis of the interface microstructure of the laminated structure revealed that the CaO–LiO–BO–SiO glass-ceramic matrix consisted of a crystalline phase of CaSiO and an amorphous phase of SiO. The interface between the Cu coil and CaO–LiO–BO–SiO glass-ceramic exhibited good bonding with no formation of secondary phases. Additionally, the strong bonding between the Cu coil and CaO–LiO–BO–SiO glass-ceramic was attributed to the diffusion of Cu atoms at the interface. The novel multilayer laminated structure based on LTCC technology proposed in this study can help achieve high-reliability insulation packaging for the stator windings of future high-power density and miniaturized flat wire motors.","PeriodicalId":501090,"journal":{"name":"Nano Materials Science","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140154975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Addressing these issues without compromising long-term stability has emerged as a pivotal focus in materials science, in particular exploring the effects of the functional groups within spacer cations. Our simulations reveal that the robust π-π stacking interactions involving PEA and the strong hydrogen bonding interactions between PEA and MX contribute to narrowing the electronic bandgap in 2D monolayer PEAMX (e. g. 2D monolayer PEASnI: 1.34 eV) for reasonable visible-light absorption while simultaneously ensuring their favorable long-term stability. Moreover, the delocalized orbitals and relatively high dielectric constants in PEA, attributed to the conjugated benzene ring, has been observed to weaken the potential barrier, exciton binding effect and quantum well confinement in 2D monolayer PEAMX, thus facilitating photogenerated electron-hole separations and out-of-plane carrier transport. The impact of spacer cations on the optoelectronic and transport properties of 2D monolayer perovskites highlights the critical role of meticulously chosen and well-designed spacer cations, especially functional groups, in shaping their photophysical properties and ensuring long-term stability even under extremely operating conditions.","PeriodicalId":501090,"journal":{"name":"Nano Materials Science","volume":"91 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140154981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cutting-edge point-of-care diagnostics for sweat biomarker analysis allow for non-invasive monitoring of physiologically related biomarkers in sweat and real-time health status tracking. Moreover, using advanced nanoarchitectures, including nanostructured platforms and nanoparticles, can enhance the specificity, sensitivity, wearability and widen the sensing modality of sweat biosensors.

Hence, it's crucial to develop adaptive shielding materials with minimum EM waves (EMW) reflection. In this paper, Ag nanoparticles loaded mesoporous carbon hollow spheres (MCHS@Ag) were synthesized by chemical reduction method, and cellulose nanofibers (CNF)/MXene/MCHS@Ag homogeneous composites were prepared. The total EM interference shielding efficiency (SE) of CNF/MXene/MCHS@Ag composite film was 32.83 dB (at 12.4 GHz), and the absorption effectiveness (SE) was improved to 26.6 dB, which was 63.1% and 195.5% higher than that of CNF/MXene/MCHS composite film. The low dielectric property of MCHS effectively optimized the impedance matching between the composites and air. The hollow porous structure prolonged the transmission path of EMW and increased the absorption loss of the composites. At the same time, Ag nanoparticles located the MCHS were helpful to construct the internal conductive path overcoming the damage of the conductive property caused by the low dielectric of MCHS. This research adopts a straightforward method to construct a lightweight, pliable, and mesoporous composites for EMI shielding, which serves a crucial role in the current era of severe EM pollution.","PeriodicalId":501090,"journal":{"name":"Nano Materials Science","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140155314","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we report the facile hydrothermal and ultrasonic treatment synthesis of 2D SnSe micro-flower modified with 0D InO nanoparticles to form SnSe/InO heterojunctions for the first time. The SnSe/InO sensor has a response value of 4.86 for 10 ppm TEA gas at 120 °C, with response and recovery times of 18 s and 79 s respectively, and detection limits as low as 100 ppb. In addition, the SnSe/InO sensor is essentially unaffected by humidity in the 30% RH to 60% RH range, and the SnSe/InO sensor response value decreases slightly in the 70% RH to 97% RH range, demonstrating excellent humidity tolerance. More importantly, the sensor maintained excellent cyclic-stability performance during a four-month cyclic stability test. The improved gas-sensitive performance can be attributed to the large number of n-n heterojunctions in the SnSe/InO material, which enhances the interfacial charge transfer, as well as the active-sites on the material surface. This work serves as a valuable complement to the TEA gas sensor and holds significant potential for detecting low concentrations of TEA at low temperatures in environmental sensing applications.","PeriodicalId":501090,"journal":{"name":"Nano Materials Science","volume":"33 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140098763","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Carbonous materials (e.g., graphite, graphene and carbon nanotubes), exhibit a wide range of unique electrical, mechanical, and thermal properties, which are also considered ideal lubricating reinforcements for metal matrix nanocomposites (MMCs) with superior mechanical and tribological properties. In this review, we first showcase the distinctive features of the constituents commonly employed in self-lubricating MMCs, encompassing the high-strength metallic matrix and nano-carbonous reinforcement.

Herein, a novel cellulose/BNNSs-AgNPs aerogel (CBAg) composed of zero-dimensional silver nanoparticles (AgNPs), one-dimensional cellulose and two-dimensional boron nitride nanosheets (BNNSs) was successfully fabricated. Specifically, AgNPs were loaded onto the surface of BNNSs, which could serve as bridges to connect adjacent BNNSs. Cellulose was used to construct a 3D skeleton structure for stabilizing better dispersion of inorganic fillers. Finally, the thermal and tribological properties of CBAg-WPU were improved compared to pure WPU, with a 69% increase in thermal conductivity and an 89% reduction in wear rate. This was attributed to the load-bearing capacity of cellulose and outstanding thermal and lubricant capability of BNNSs-AgNPs. In addition, BNNSs and AgNPs inside the aerogel were transferred to the sliding interface and participated in the formation of high-quality friction transfer film, further endowing CBAg-WPU composites prominent tribological performance.
