The ceramic cone is post-process fired to achieve a pure ceramic cone that is coated with emitting CNT mesh film. Meanwhile, a cone-based polymer emitter is evaluated. The resulting emitter exhibits non-linear current-voltage characteristics reaching maximum 0.6 mA anode current with a turn-on-field voltage below 1 Vµm−1 and minimal current fluctuation over time. Additionally, the ceramic emitter arrays fabricated using the same technique are demonstrated: if the tip angle and shape in a microscale have tunability in emission is confirmed, meanwhile, the type of volatile gases released during the emission is confirmed using a residual gas analyzer (RGA). The motivation and challenge are to use 3D printing to enable freedom in designing and forming the emitter tip shape and angle and to present the perspective and challenges to use the 3D printing technique combined with the seamless shaping for the CNT mesh film to tune the emitter performance. Especially as this technique and 3D-printed materials have not been previously employed for electron emitters.","PeriodicalId":7292,"journal":{"name":"Advanced Materials Technologies","volume":"10 8","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admt.202401609","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143840872","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These materials utilize 3,6-bis(trifluoromethyl)-9H-carbazole (CF3Cz) as the donor (D), and pyrimidine (Pym) or pyridine (Py) as the acceptor, with features of structural modifications aimed at enhancing stability and luminescence efficiency. In particular, the introduction of strong electron-withdrawing CF3 groups helps stabilize the highest occupied molecular orbital (HOMO) energy level, while electron-donating groups like tert-butyl group, carbazole, and N,N-dimethylamine destabilize the lowest unoccupied molecular orbital (LUMO), resulting in high triplet energy levels crucial for green OLED performance. CF3Cz–2CzPym exhibits outstanding electroluminescent properties when doped with Ir(ppy)3, achieving a maximum external quantum efficiency (EQE) of 18.5% and a luminance efficiency of 64.6 cd A−1 with a low turn-on voltage of 2.6 V. Additionally, when combined with the electron-transporting material bis-4,6-(3,5-di-3-pyridylphenyl)-2-methylpyrimidine (B3PyMPM) to form a co-host system, these materials further improve charge balance and green OLED efficiency, attaining a maximum EQE of 19.8% and a peak luminescence efficiency of 68.4 cd A−1.

However, a conflict between start-up and saturation rotation speed of wind energy harvester hinders the adaptive energy collection from low to strong wind speeds in different wind speed ranges. Herein, a self-powered system by an aerodynamic-complementary triboelectric-electromagnetic hybridized generator (AC-TEHG) equipped with a triple-mode switching power management topology (TmSPMT) is proposed to achieve self-adaptive power supply mode switching in response to different wind speed ranges. Specifically, AC-TEHG integrates Savonius and wind cup miniaturized turbine to achieve layered energy collection over wide-range wind speed regions (1.4–16.3 m s−1), where the triboelectric nanogenerator (TENG) and electromagnetic generator (EMG) units have the excellent electrical output with Voc, Isc, and instantaneous peak power reaching 664 V/10.83 V, 35.96 µA/19.84 mA and 8.01 mW/62.45 mW, respectively. AC-TEHG equipped with TmSPMT can effectively respond to different wind speed ranges of windlessness, low, medium, and high wind speeds for steadily powering commercial electronics. Finally, a wireless self-powered climate monitoring system is developed to indicate that AC-TEHG equipped with TmSPMT is a sustainable solution to efficiently power Internet of Things sensors in regions with variable wind speeds.","PeriodicalId":7292,"journal":{"name":"Advanced Materials Technologies","volume":"10 9","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143905382","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work presents the fabrication of stretchable polymeric matrices for 3D inductors through a single-step method via additive manufacturing. A multi-jet modeling (MJM) type 3D printer is used to print a stretchable and rigid hybrid matrix by leveraging the features of high-resolution and multi-component printing techniques. Owing to the presence of access channels designed in multiple directions, the coil channel shows a clean and smooth surface with uniformity. A room-temperature liquid metal, the eutectic gallium indium (EGaIn) alloy, is encapsulated in the designated channels without any leakage under mechanical deformation. Electrical performance tests demonstrate that the MJM-printed solenoid and toroid inductors maintain stable performance under bending and stretching deformations, which is suitable for soft electronic applications. Additionally, a flexible helical structured inductor is fabricated and tested as a wireless power receiver inductor. It generated an output voltage of more than 10 V, sufficient to power a red LED light bulb. These results highlight the simplicity and effectiveness of multi-jet 3D printing for fabricating a stretchable and rigid hybrid matrix for the inductors at once, with excellent mechanical deformability and electrical performance.","PeriodicalId":7292,"journal":{"name":"Advanced Materials Technologies","volume":"10 9","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admt.202401601","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143905400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In 2D TMDC-based phototransistors, 1/f noise, caused by complex defect states, acts as a dominant low-frequency noise (LFN) and is crucial for obtaining accurate photodetection characteristics. However, many studies still overlook LFN and focus on enhancing photocurrent or response time. In this study, the importance of LFN analysis is highlighted in WSe2 phototransistors and demonstrate reduced noises and enhanced photodetection performance through the suppression of metal-induced gap states (MIGS) that act as noise sources by utilizing semimetal bismuth (Bi) contact. The WSe2 phototransistors demonstrated ≈1000 times lower noise, 100 times higher responsivity, and 10 times higher specific detectivity than devices with conventional metal contacts. The results of this study suggest that reducing LFN in photodetection devices, such as by suppressing MIGS, can be an efficient way to enhance device performance.","PeriodicalId":7292,"journal":{"name":"Advanced Materials Technologies","volume":"10 9","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143905399","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fortunately, for many applications, the number of possible molecules in the specimen is small or limited. For such cases, a protocol is presented that uses only a small number of very sensitive hence expensive detectors. The protocol starts with optimizing spectral regions, one per detector, so that different molecules become best distinguishable. Experimentally, the spectral regions are extracted from the continuous spectrum using a custom-made micro-optical element. In the ray-optics picture, it guides all rays in a spectral region onto the entrance of an optical fiber connected to one detector. The shape of the micro-optical element is derived by applying Snell's law to the given geometrical boundary conditions. A proof-of-concept measurement using a dedicated demonstrator refractive optical element in combination with a continuous white-light source is performed. Indeed, the element selects the correct spectral regions and couples the light into the correct fibers. For the example of the identification of single amino acids in a protein, the protocol leads to a higher correct identification rate. Therefore, this protocol is useful for such protein identification experiments as performed in the EU project ProID.","PeriodicalId":7292,"journal":{"name":"Advanced Materials Technologies","volume":"10 9","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admt.202401876","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143905398","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
