Scientific community attention towards these substances has been increasing, because of their peculiar characteristics in combining anticipated features of building constructs for specified applications. Graphene oxide (GO) and metal nanoparticles (MNPs) are using separately in different applications due to their specific limitations. Researchers continue to explore ways to overcome these challenges and create functional nanomaterials for various fields by combining unique advantages of GO and MNPs. Here, we used a facile one-step method for the synthesis of reduced graphene oxide–palladium composite (RGO/Pd). Environmental-friendly biofabricated palladium nanoparticles adhered to <i>Polyscias scutellaria</i> (PS) leaf extract mediated RGO/Pd have been presented in the current investigation. The biofabricated nanohybrid (RGO/Pd) was analysed utilizing several microscopic and spectroscopic techniques. Further, we have also examined the catalytic function for the reduction of 2-nitroaniline (2-NA) in detail. Primarily, we observed that the synthesized nanocomposite can catalyse simultaneous reduction of 2-NA. Furthermore, an added advantage of the as prepared RGO/Pd nanocomposite is its antimicrobial and antifungal ability. Further, we exhibited that the mesenchymal stem cells of adult goat were viable in the presence of RGO/Pd of 0.1 mg/mL concentration and their properties of stem cells were retained. The outcomes displayed that the nanocomposites exhibited outstanding functioning in the killing of dangerous microbial and fungal pathogens. All these results strengthen the RGO/Pd composite applicability in future for potential therapy in bone tissue engineering applications.</p></div>","PeriodicalId":8374,"journal":{"name":"Applied Water Science","volume":"14 10","pages":""},"PeriodicalIF":5.7,"publicationDate":"2024-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13201-024-02271-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142231272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the Mediterranean region, groundwater resources are highly vulnerable to natural and anthropogenic pressures, such as overexploitation, climate change, seasonal variations in precipitation, and seawater intrusion. Hence, an understanding of hydrogeological processes and groundwater chemistry is a basis for the sustainable management of coastal and island groundwater resources. Vis, a small and remote karst island in the Adriatic Sea, exhibits peculiar geological and hydrogeological settings, resulting in the island’s autonomous water supply. The current pumping capacity (maximum of 42 l/s) meets most of the demand, but intensive summer tourism and climate change exert high stress on groundwater resources during the dry season. Consequently, in the last decade, occasional reductions for consumers occurred. Monitoring of in situ physicochemical parameters and groundwater sampling for chemical and isotopic analyses were conducted from 2020 to 2023 at deep borewells, shallow dug wells, and springs. Hydrochemical interpretation indicated that groundwater chemistry was affected primarily by carbonate and sulfate rock dissolution, mixing with seawater, reverse ion exchange, and dedolomitization. The majority of groundwater samples exhibit Ca–HCO<sub>3</sub> hydrochemical facies, followed by Na–Cl and mixed facies. The low percentage of seawater in the mixture indicated that seawater intrusion is not too extensive even during prolonged dry periods, implying a favorable hydrostatic regime with relatively small but sufficient groundwater reserves of the island’s aquifers, although the investigated period was characterized by significantly lower precipitation with respect to the 30-year average.</p></div>","PeriodicalId":8374,"journal":{"name":"Applied Water Science","volume":"14 10","pages":""},"PeriodicalIF":5.7,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13201-024-02278-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142158787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Meteorological and hydrological drought indicators along with precipitation and flow rate were used as input variables for prediction. The simulation results revealed a groundwater level decrease since the aquifer withdrawal amount is more than the recharge amount. Besides, results showed that there is a limited interaction between surface water and groundwater resources, mainly caused by the decrease in the river flow and aquifer groundwater level drop.
