Nickel (0) Complexes as Promising Chemosensors for Detecting the “Cork Taint” in Wine

چکیده
2,4,6-Trichloroanisole (TCA) is well recognized as one of the most responsible molecules cork taint, an organoleptic defect wine which represents a serious problem for industries. Up to now, very few examples TCA-biosensors have been developed and we report herein promising nickel (0) complex that can be employed chemosensor TCA detection in stoppers. Among three Ni complexes studied this work, Ni(0)(BINAP)(η2-PhCN) (2) showed best reactivity towards pure affording oxidative addition product 4 four hours at room temperature. Compound appealing probe indirect quantification due presence characteristic UV-adsorption band 444 nm. Statistical studies on real samples confirmed detected by employing UV-Visible spectroscopy, demonstrated PCA analyses allowed distinguishing TCA-contaminated from non-contaminated ones. Even if present study has considered preliminary approach realization usable systems, here reported (0)-based sensing procedure first chemical detection.

the search for the self in becketts theatre: waiting for godot and endgame
this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...
15 صفحه اولStatic analysis for detecting taint-style vulnerabilities in web applications
The number and the importance of web applications have increased rapidly over the last years. At the same time, the quantity and impact of security vulnerabilities in such applications have grown as well. Since manual code reviews are time-consuming, error-prone and costly, the need for automated solutions has become evident. In this paper, we address the problem of vulnerable web applications ...
متن کاملGraphdiyne as a promising material for detecting amino acids
The adsorption of glycine, glutamic acid, histidine and phenylalanine on single-layer graphdiyne/graphene is investigated by ab initio calculations. The results show that for each amino acid molecule, the adsorption energy on graphdiyne is larger than the adsorption energy on graphene and dispersion interactions predominate in the adsorption. Molecular dynamics simulations reveal that at room t...
