Ionic liquids for the removal of sulfur and nitrogen compounds in fuels: a review Environ. Chem. Lett. (IF 5.922) Pub Date : 2021-01-04 N. Evelin Paucar, Peyton Kiggins, Bryson Blad, Karl De Jesus, Farjana Afrin, Srinath Pashikanti, Kavita Sharma
Air pollution is partly due to the emission of toxic sulfur and nitrogen oxides during fuel combustion. Therefore, these compounds should be removed from fuels. For that, ionic liquids have been recently developed to extract sulfur and nitrogen compounds from petroleum and fuels. Ionic liquids can extract S- and N-containing compounds either simultaneously or selectively. Ionic liquids usage appears

Modeling the toxicity of pollutants mixtures for risk assessment: a review Environ. Chem. Lett. (IF 5.922) Pub Date : 2021-01-03 M. Sigurnjak Bureš, M. Cvetnić, M. Miloloža, D. Kučić Grgić, M. Markić, H. Kušić, T. Bolanča, M. Rogošić, Š. Ukić
The occurrence of contaminants in natural waters is a potential threat to the environment. Since contaminants are commonly present as mixtures, numerous interactions may occur, resulting in lower or, more dangerously, higher toxicity, by comparison with single substances. The toxicity of multicomponent systems can be determined experimentally, but toxicity prediction by suitable models is faster, environmentally

Phytotherapy with active tea constituents: a review Environ. Chem. Lett. (IF 5.922) Pub Date : 2021-01-03 Ajay Rana, Shalika Rana, Sanjay Kumar
Tea is a widely renowned functional beverage originating from processed tender leaves of the Camellia sinensis plant after brewing with hot water. This refreshing and revitalizing beverage has been recognized as an essential commodity since ancient times. Tea constituents have many health benefits and hence find usage in functional foods, beverages, and nutraceuticals. Nonetheless, the clinical usage

Occurrence and removal of antibiotics from industrial wastewater Environ. Chem. Lett. (IF 5.922) Pub Date : 2021-01-03 D. Akhil, Divya Lakshmi, P. Senthil Kumar, Dai-Viet N. Vo, A. Kartik
Water recycling is of increasing concern due to the shortage of natural resources, calling for advanced methods to remove contaminants. Indeed, the transfer of contaminants to living organisms may lead to bioaccumulation and diseases. In particular, the overuse of antibiotics for human and animal health has led to antibiotic pollution in waters, sludges and crop soils, and, in turn, to the unintended

Green synthesis of 1,4-dihydropyridines using cobalt carbon nanotubes as recyclable catalysts Environ. Chem. Lett. (IF 5.922) Pub Date : 2021-01-03 Kaier Wu, Yuye Bai, Dewei Chen, Lu Chen, Yubing Huang, Shuli Bai, Yibiao Li
Heterocyclic compounds occur widely in nature and in drug molecules. The activity of many nitrogen-containing heterocyclic compounds is unique. For example, 1,4-dihydropyridines display good antitumor and antibacterial effects and can be commercially used as calcium channel blocker agents in the treatment of cardiovascular diseases. To reduce the use of toxic catalysts in the synthesis of 1,4-dihydropyridines

Fluorescence sensing of microplastics on surfaces Environ. Chem. Lett. (IF 5.922) Pub Date : 2021-01-03 Camila Q. V. Costa, Joana Cruz, Jorge Martins, Maria Alexandra A. Teodósio, Steffen Jockusch, V. Ramamurthy, José P. Da Silva
Microplastics, nanoplastics and related products have been recently found in marine ecosystems worldwide, calling for new analytical methods for rapid detection and risk assessment. Fluorescence is a sensitive technique that when used with polarity probes can potentially detect low-polarity plastic particles in environments. Here, we evaluated the fluorescence technique to sense polystyrene microparticles

Oxygen vacancy confining effect on photocatalytic efficiency of Pt 1 -black TiO 2 single-atom photocatalysts for hydrogen generation and phenol decomposition Environ. Chem. Lett. (IF 5.922) Pub Date : 2021-01-03 Tian Wang, Yunqing Zhu, Zhaoyue Luo, Yingxuan Li, Junfeng Niu, Chuanyi Wang
Energy and pollution are major issues worldwide, calling for advanced techniques of biofuel production and environmental remediation, such solar photocatalysis. Engineering the co-catalyst at atom level has recently been proposed to increase the photocatalytic efficiency. Here, we report a new strategy for preparing highly stable single-atom photocatalysts containing abundant isolated atomic sites
