Dioxidomolybdenum(VI) and –tungsten(VI) complexes with tetradentate amino bisphenolates as catalysts for epoxidation
2017
Sixteen molybdenum and tungsten complexes with tripodal or linear tetradentate amino bisphenol ligands were studied as catalysts for the epoxidation of cis-cyclooctene, 1-octene, styrene, limonene and α-terpineol. These complexes can be divided into different categories upon key features, i.e. central metal (Mo versus W), side-arm donor (O versus N), hybridization of the N-donor (pyridine versus amine), ligand geometry (tripodal versus linear diamine) and sterical hindrance (Me versus tert-Bu substituents in the phenol part). All complexes can catalyse selectively the epoxidation of cis-cyclooctene by tert-butylhydroperoxide whereas the activities and selectivities towards other olefins (1-…
The spectrum of allergic (cross-)sensitivity in clinical patch testing with 'para amino' compounds
2002
Background: Allergic contact sensitization to ‘para amino’ compounds is frequent and the spectrum of cross-reactivity between members of this chemical group is variable. Methods: A retrospective analysis of clinical patch test data obtained with a special test series in the centres of the Information Network of Departments of Dermatology (IVDK) between 1995 and 1999. Results: In the 638 patients tested with the above test panel positive reactions were observed most often to p-aminoazobenzene (16.2%), p-phenylenediamine (14.1%), p-toluylenediamine (10.0%), followed by 4,4′-diaminodiphenylmethane (8.5%), Disperse Orange 3 (8.4%) and p-aminophenol (3.1%). Among the 544 patients tested with p-p…

Effects of indomethacin on muscarinic inhibition of endogenous noradrenaline release from rat isolated trachea
1993
The release of endogenous noradrenaline from rat isolated tracheae was evoked by electrical field stimulation (3 Hz, 540 pulses) in the presence of yohimbine, desipramine and tyrosine. The muscarine receptor agonist oxotremorine concentration-dependently inhibited the evoked release of noradrenaline by 95% at 1 μmol/l, EC50 values in two series of experiments 41 and 57 nmol/l, respectively. The effect of oxotremorine was antagonized by the non-selective muscarine receptor antagonist scopolamine (10–1000 nmol/l) in a manner suggesting a simple competitive interaction (slope of Schild plot −0.94; pA2 value 8.88). However, the M2 selective muscarine receptor antagonist methoctramine (0.1–10 μm…

Metodi Chemiometrici per la sintesi razionale di Nanowires di ZnO per l'elettronica su Circuiti
2019
I nanowires di ZnO (ZnO NWs) rappresentano uno dei materiali 1D di maggiore interesse per lo sviluppo di sensori e/o trasduttori, date le loro ot time proprietà piezoelettriche e semiconduttive1 . Tuttavia, la sintesi chimica di ZnO NWs ad alto “aspect ratio” da soluzione acquosa a basse temperature stemi elettronici completi. Recentemente abbiamo sviluppato2 un metodo per il controllo razionale della sintesi di nanowires di ZnO (Figura 1) su supporti conduttivi in rame per la realizzazione di nanotrasduttori...
