The mitochondrial oxygen consumption rate and a transmission electron

Silver(I) Coordination Polymers: Photocatalytic Properties and Enhanced Treatment Activity of Haloperidol on Children Tic Disorder by Regulating Neurotransmitter Content. J. Fluoresc. (IF 2.093) Pub Date : 2020-09-15 Hui-Li Qian,Xin Yu,Guo-Feng Liu
In this article, the characterization, synthesis, as well as the photocatalysis dye degradation performance of two novel silver(I) coordination polymers, namely, [Ag(L)(Hbdc)]n (1, L = 1,4-Bis(5,6-dimethylbenzimidazol-1-yl)butane, H2bdc = 1,4-Benzenedicarboxylic acid) and [Ag2(L)(hip)]n (2, H2hip = 5-Hydroxyisophthalic acid), were investigated. Fascinatingly, the photocatalytic performance of Complexes

A Mini Review on Organic Chemosensors for Cation Recognition (2013-19). J. Fluoresc. (IF 2.093) Pub Date : 2020-09-15 Nilima S Patil,R B Dhake,Mohd Imran Ahamed,Umesh Fegade
Colorimetric and ratiometric fluorescent probe for cations gain very well attention by the chemist, biologist and environmentalist. Metals has two sides, first is biolgical active for living creature and toxic nature for the ecosystem. From last three decades the scientists are contiously trying to find out the best solution for the detection of cations at micro as well as nanomolar levels. In the

A Fluorescence Resonance Energy Transfer Biosensor Based on Graphene Quantum Dots and Protoporphyrin IX for the Detection of Melamine. J. Fluoresc. (IF 2.093) Pub Date : 2020-09-12 Gao Xue,Ma Zhiying,Liu Xiuying,Tang Lijun,Li Jianrong
Graphene quantum dots (GQDs), which have high photostability, anti-photobleaching and scintillation, good biocompatibility and low toxicity, are important member of the fluorescent material family, and have attracted extensive research interest. In this paper, a fluorescence resonance energy transfer (FRET) biosensor based on protoporphyrin IX (PpIX) and GQDs was developed for melamine detection. PpIX
