The Ti-45Nb (mass%) alloy’s corrosive and biocompatible response in simulated physiological conditions was investigated before and after its additional high-pressure torsion (HPT) and laser irradiation processing. The grain size reduction from 2.76 µm to ~ 200 nm and the appearance of laser-induced morphologically altered and highly oxidized surface led to the significant improvement of alloy corrosion resistance and cell–implant interaction. Moreover, an additional increase of the laser pulse energy from 5 to 15 mJ during the alloy irradiation in the air led to an increase in the surface oxygen content from 13.64 to 23.89% accompanied by an increase of excellent cell viability from 127.18 to 134.42%. As a result of the controlled alloy microstructural and surface modifications, the formation of protective bi-modal mixed Ti- and Nb-oxide external scale was enabled. The presence of this surface oxide scale enhanced the alloy’s resistance to corrosion deterioration and simultaneously boosted cell viability and proliferation.

The occurrence of emerging organic contaminants(EOCs)was investigated in vulnerable Dinaric karst catchment of Jadro andZrnovnica springs in Croatia,under varying flow conditions and across three different water resource types(groundwater,springs,and surface water).The maximal EOCs concentration in both springs were observed following autumn recharge events,while during peak discharge no detection above the limits of detection(LOD)was recorded due to dilution *** to springs,groundwater from deep borehole exhibited highest total EOCs concentration under low flow conditions,underscoring the considerable karst aquifer vulnerability and its oligotrophic *** peak EOCs concentration in karstic Cetina River coincided with the river's lowest *** highest mass flux of 1013 g/day was determined for very mobile pharmaceutical metformin detected in *** presence of potentially persistent to very persistent compounds,like DEET and 1H-benzotriazole,which exhibited highest detection frequencies across all sampling sites,was observed in association with varying hydrological *** regarding the occurrence of identified EOCs include surface contamination infiltrating directly through ponors and highly karstified areas,potential persistence in the epikarst and aquifer matrix,and site-specific contamination sources for compounds such as 1H-benzotriazole,gabapentin,and ketoprofen found in *** evaluate the risk of inadvertent human exposure to EOCs across various age groups,we utilized measured spring concentrations and calculated drinking water equivalent levels(DWEL),which ranged from 1.4 mg/L for cotinine to 503 mg/L for sucralose,both detected in Jadro *** EOCs concentrations in ng/L are unlikely to pose a significant risk to healthy population,long-term exposure to EOCs mixture remains *** scarcity of research on EOCs in karst environments on both global and national levels,our study enhances comp
