However, the efficient use of renewable energy sources and the emergence of wearable electronics has created the need for new requirements such as high-speed energy delivery, faster charge–discharge speeds, longer lifetimes, and reusability. This leads to the need for supercapacitors, which can be a good complement to batteries. However, one of their drawbacks is their lower energy storage capability, which has triggered worldwide research efforts to increase their energy density. With the introduction of novel nanostructured materials, hierarchical pore structures, hybrid devices combining these materials, and unconventional electrolytes, significant developments have been reported in the literature. This paper reviews the short history of the evolution of supercapacitors and the fundamental aspects of supercapacitors, positioning them among other energy-storage systems. The main electrochemical measurement methods used to characterize their energy storage features are discussed with a focus on their specific characteristics and limitations. High importance is given to the integral components of the supercapacitor cell, particularly to the electrode materials and the different types of electrolytes that determine the performance of the supercapacitor device (e.g., storage capability, power output, cycling stability). Current directions in the development of electrode materials, including carbonaceous forms, transition metal-based compounds, conducting polymers, and novel materials are discussed. The synergy between the electrode material and the current collector is a key factor, as well as the fine-tuning of the electrode material and electrolyte.}, year = {2024}, eissn = {1996-1944} } @article{MTMT:34445158, title = {AlSi7Mg0.3 ötvözet in situ szakítóvizsgálata számítógépes röntgen tomográfia (CT) segítségével}, url = {https://m2.mtmt.hu/api/publication/34445158}, author = {Kazup, Ágota and Gácsi, Zoltán}, journal-iso = {Doktorandusz Almanach}, journal = {Doktorandusz Almanach}, volume = {2023}, unique-id = {34445158}, issn = {2939-7294}, year = {2023}, pages = {7-13} } @misc{MTMT:34256309, title = {Alumínium öntvények mechanikai és pórusszerkezeti jellemzőinek vizsgálata}, url = {https://m2.mtmt.hu/api/publication/34256309}, author = {Kazup, Ágota and Gácsi, Zoltán}, unique-id = {34256309}, year = {2023} } @article{MTMT:34123864, title = {Morphological and mechanical evolution of α-Al2O3 reinforced Mo Cu alloy obtained by planetary ball milling}, url = {https://m2.mtmt.hu/api/publication/34123864}, author = {Pethő, Dániel and Kurusta, Tamás and Koncz-Horváth, Dániel and Kristály, Ferenc and Mikó, Tamás and Pal, Manoj Kumar and Gácsi, Zoltán}, doi = {10.1016/j.jmapro.2023.08.034}, journal-iso = {J MANUFACT PROCES}, journal = {JOURNAL OF MANUFACTURING PROCESSES}, volume = {103}, unique-id = {34123864}, issn = {1526-6125}, year = {2023}, eissn = {2212-4616}, pages = {1-10}, orcid-numbers = {Kristály, Ferenc/0000-0002-0075-5994} } @article{MTMT:34107259, title = {Additive Manufacturing of 17-4PH Alloy: Tailoring the Printing Orientation for Enhanced Aerospace Application Performance}, url = {https://m2.mtmt.hu/api/publication/34107259}, author = {Kovács, Sándor Endre and Mikó, Tamás and Troiani, Enrico and Markatos, Dionysios and Pethő, Dániel and Gergely, Gréta Katalin and Varga, László and Gácsi, Zoltán}, doi = {10.3390/aerospace10070619}, journal-iso = {AEROSPACE-BASEL}, journal = {AEROSPACE}, volume = {10}, unique-id = {34107259}, abstract = {Additive manufacturing (AM) is one of the fastest-growing markets of our time. During its journey in the past 30 years, its key to success has been that it can easily produce extremely complex shapes and is not limited by tooling problems when a change in geometry is desired. This flexibility leads to possible solutions for creating lightweight structural elements while keeping the mechanical properties at a stable reserve factor value. In the aerospace industry, several kinds of structural elements for fuselage and wing parts are made from different kinds of steel alloys, such as 17-4PH stainless steel, which are usually milled from a block material made using conventional processing (CP) methods. However, these approaches are limited when a relatively small element must withstand greater forces that can occur during flight. AM can bridge this problem with a new perspective, mainly using thin walls and complex shapes while maintaining the ideal sizes. The downside of the elements made using AM is that the quality of the final product is highly dependent on the build/printing orientation, an issue extensively studied and addressed by researchers in the field. During flight, some components may experience forces that predominantly act in a single direction. With this in mind, we created samples with the desired orientation to maximize material properties in a specific direction. The goal of this study was to demonstrate that an additively manufactured part, produced using laser powder bed fusion (LPBF), with a desired build orientation has exceptional properties compared to parts produced via conventional methods. To assess the impact of the build orientation on the LPBF parts’ properties, one-dimensional tensile and dynamic fracture toughness tests were deployed.}, year = {2023}, eissn = {2226-4310}, orcid-numbers = {Troiani, Enrico/0000-0003-0021-1433} } @article{MTMT:34072889, title = {Machine learning-assisted characterization of electroless deposited Ni–P particles on nano/micro SiC particles}, url = {https://m2.mtmt.hu/api/publication/34072889}, author = {Gyökér, Zoltán Dávid and Gergely, Gréta Katalin and Takáts, Viktor and Gácsi, Zoltán}, doi = {10.1016/j.ceramint.2023.06.242}, journal-iso = {CERAM INT}, journal = {CERAMICS INTERNATIONAL}, volume = {49}, unique-id = {34072889}, issn = {0272-8842}, year = {2023}, eissn = {1873-3956}, pages = {29849-29856} } @article{MTMT:34054967, title = {Electrochemical behavior of GNP/CNT porous composite for supercapacitor}, url = {https://m2.mtmt.hu/api/publication/34054967}, author = {Pandit, Niranjan and Singh, Pushpender and Prasad, Suraj and Kumar Keshri, Anup and Czagány, Máté and Hompoth, Szabolcs and Gácsi, Zoltán and Baumli, Péter}, doi = {10.1016/j.cplett.2023.140695}, journal-iso = {CHEM PHYS LETT}, journal = {CHEMICAL PHYSICS LETTERS}, volume = {827}, unique-id = {34054967}, issn = {0009-2614}, year = {2023}, eissn = {1873-4448}, orcid-numbers = {Singh, Pushpender/0000-0002-1386-2289} } @misc{MTMT:34045142, title = {Számítógépi tomográfia alkalmazása alumínium öntvények vizsgálatára}, url = {https://m2.mtmt.hu/api/publication/34045142}, author = {Kazup, Ágota and Molnár, Zsolt and Fegyverneki, György and Gácsi, Zoltán}, unique-id = {34045142}, abstract = {IV.
