Article Silver-Loaded Titania-Based Metal-Organic Frameworks as a Platform for Silver Ion Release for Antibacterial Applications(American Chemical Society, 2025) Mazare, Anca; Goldmann, Wolfgang Heinrich; Kocak, Esra; Osuagwu, Benedict; Qin, Shanshan; Cao, Ran; Schmuki, PatrikConventional Ag-decorated TiO<inf>2</inf>coatings suffer from low adsorption capacity and burst release kinetics, limiting long-term antibacterial efficacy and risking cytotoxicity. An entirely different payload release approach can be based on metal–organic frameworks (MOFs), which offer tunable porosity, high surface area, and internal diffusion channels. Here, we report a thermally stabilized Ti-based MOF [NH<inf>2</inf>-MIL-125(Ti)] functionalized with Ag+via reactive deposition, enabling high Ag loading (∼14.7 wt %) and sustained release. Annealing at 250 °C enhances aqueous stability, allowing diffusion-governed Ag+delivery over >48 h, with 77% of the Ag still present in the MOF after a 24 h release. The system exhibits dose-dependent antibacterial activity in powders and comparable efficacy in coatings, with a more gradual release profile. This scalable platform is promising for long-acting coatings, wound interfaces, and implantable materials. © 2025 Elsevier B.V., All rights reserved.Article Citation - WoS: 12Citation - Scopus: 14Identifying Geogenic and Anthropogenic Aluminum Pollution on Different Spatial Distributions and Removal of Natural Waters and Soil in Çanakkale, Turkey(Amer Chemical Soc, 2023) Hızlı, Sezin; Koraoğlu, Aybike Gül; Gören, Ayşegül Yağmur; Kobya, MehmetThe Canakkale-Kirazli region (Turkey) is enriched with minerals, especially aluminum (Al), which dangerously get transported into aquatic media due to several mining and geological activities in recent years. In this study, Al and other potentially toxic metals (PTMs) including B, Ba, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Si, and Zn, in both water and soil samples, were measured for quality determination. Selected metals were also analyzed by the enrichment factor (EF), the geoaccumulation index (I-geo), the contamination factor (CF), and the pollution load index (PLI) to evaluate both water and soil pollution geogenically or anthropogenically. Also, the metals were clustered to support the pollution source with Pearson's correlation, principal component analysis (PCA), and hierarchical cluster analysis (HCA). Forty-five natural water samples and 12 soil samples were collected spatially. To perform pollution assessment, two fundamental treatment processes to remove Al pollution from the sample including the highest Al concentration (38.38 mg/L) in water were applied: (1) precipitation with pH adjustment and (2) removal with ion exchange. The pH values of water samples were changed in the range of 3-9 to test the dissolution of Al. The results demonstrated that the study area was mostly under the influence of geogenic aluminum pollution.Editorial Citation - WoS: 2Citation - Scopus: 1Preface(Elsevier Ltd., 2012) Yalçın, Şerife; Fantoni, RobertaThe sixth in traditional series of biennial Euro-Mediterranean Symposium on Laser-Induced Breakdown Spectroscopy, EMSLIBS' 2011, was held in a beautiful destination for holiday renowned for its gorgeous beaches, Çeşme‐Izmir, Turkey, between 11 and 15th of September 2011. EMSLIBS' 2011 was organized by the Chemistry Department of Izmir Institute of Technology, IZTECH, and supported by three industrial companies of Turkey: Tüpraş, Elginkan Foundation and Zentiva.
