Wed, 01 Jul 2026 00:00:00 GMT https://hdl.handle.net/10442/19860 2026-07-01T00:00:00Z Viskadourakis, Z. Orfanou, M. Pitilakis, A. Τσιλιπάκος Οδυσσέας Κoudoumas, E. Kenanakis, G. In the current study, a microwave device based on a metasurface is investigated regarding its potential application as a pH sensor. The device was developed on a typical double-sided, Cu−coated FR-4 slide, utilizing the mechanical engraving method. It was electromagnetically characterized in the microwave band, i.e., 1–5 GHz. Furthermore, theoretical simulations were performed to confirm the measured electromagnetic response. Moreover, the fabricated device was tested against standard buffer solutions, such as those used for the calibration of conventional potentiometric pH meters, as well as against home-made acidic and basic aqueous solutions, with pH levels ranging from 2 up to 12. By analyzing the corresponding electromagnetic response, it is evident that the aforementioned pH device demonstrates a gradual response in varying pH levels. Furthermore, it exhibits adequate quality factor, sensitivity, and figure of merit values, indicating a measurable and application-relevant electromagnetic performance. Considering the above, it is evidently shown that the proposed metasurface−based device could be potentially used for the detection of pH levels in aqueous solutions. https://hdl.handle.net/10442/19839 Title: MOFSynth-ADV: An Open-Source Engine for Synthesizability Evaluation of Metal-Organic Frameworks Creator: Livas, Charalampos G; Klontzas, Emmanuel; Trikalitis, Pantelis N; Froudakis, George E Wed, 29 Apr 2026 00:00:00 GMT https://hdl.handle.net/10442/19839 2026-04-29T00:00:00Z Livas, Charalampos G Klontzas, Emmanuel Trikalitis, Pantelis N Froudakis, George E https://hdl.handle.net/10442/19840 Title: Effect of Ion Specificity on the Interfacial Behavior of Amphiphilic Hyperbranched Copolymer H-P(OEGMA-co-LMA) Creator: Wei, Yuqing; Wen, Gangyao; Balafouti, Anastasia; Pispas, Stergios; Sun, Zhaoyan; Li, Hongfei Thu, 23 Apr 2026 00:00:00 GMT https://hdl.handle.net/10442/19840 2026-04-23T00:00:00Z Wei, Yuqing Wen, Gangyao Balafouti, Anastasia Pispas, Stergios Sun, Zhaoyan Li, Hongfei https://hdl.handle.net/10442/19833 Title: Lipid/copolymer hybrid drug delivery systems: From design to performance Creator: Triantafyllopoulou, Efstathia; Selianitis, Dimitrios; Chountoulesi, Maria; Karayianni, Maria; Valsami, Georgia; Πίσπας, Στέργιος; Pippa, Natassa Mon, 30 Mar 2026 00:00:00 GMT https://hdl.handle.net/10442/19833 2026-03-30T00:00:00Z Triantafyllopoulou, Efstathia Selianitis, Dimitrios Chountoulesi, Maria Karayianni, Maria Valsami, Georgia Πίσπας, Στέργιος Pippa, Natassa https://hdl.handle.net/10442/19832 Title: High-performance oxygen reduction electrocatalysis enabled by NicorePdshell nanoparticles immobilized on MoS2 nanosheets Creator: Minadakis, Michail P.; Sato, Yuta; Canton-Vitoria, Ruben; Suenaga, Kazu; Tagmatarchis, Nikos Wed, 18 Mar 2026 00:00:00 GMT https://hdl.handle.net/10442/19832 2026-03-18T00:00:00Z Minadakis, Michail P.
