Light and Divine Wisdom: An Alternative Interpretation of the Iconography of the Fuller Brooch
2022
La spilla di Fuller viene considerata una rappresentazione, in ambito inglese, dei cinque sensi. Si ritiene che il personaggio centrale, che rappresenta la vista, presenti anche uno o più significati figurativi, legati a idee e concetti che erano correnti nel contesto culturale di re Alfredo. Questi significati figurativi dovevano presumibilmente essere enfatizzati e chiariti dai due oggetti che questa figura regge. Finora, tuttavia, questi oggetti non sono stati interpretati in modo soddisfacente, anche se la maggior parte degli studiosi ritiene che essi possano rappresentare delle piante o cornucopie. Il presente studio esplora l'ipotesi che questi oggetti siano in realtà delle torce, att…

A fluorescence study of the loading and time stability of doxorubicin in sodium cholate/PEO-PPO-PEO triblock copolymer mixed micelles
2019
Abstract Hypothesis Doxorubicin hydrochloride (DX) is one of the most powerful anticancer agents though its clinical use is impaired by severe undesired side effects. DX encapsulation in nanocarrier systems has been introduced as a mean to reduce its toxicity. Micelles of the nonionic triblock copolymers of poly(ethylene oxide) (PEO) and poly(propylene oxide) (PPO) (PEO-PPO-PEO), are very promising carrier systems. The positive charge of DX confines the drug to the hydrophilic corona region of the micelles. The use of mixed micelles of PEO-PPO-PEO copolymers and a negatively charged bile salt should favour the solubilization of DX in the apolar core region of the micelles. Experiments We st…

Two new organic-selenate salts: syntheses and crystal structures of bis(di-iso-propylammonium) selenate and di-n-butylammonium hydrogenoselenate
2017
Abstract Two new dialkyammonium selenate salts [i-Pr2NH2]2[SeO4] (1) and [n-Bu2NH2][HSeO4] (2) have been isolated and characterized by single-crystal X-ray diffraction. Salt 1 crystallizes in the monoclinic system, space group P21/n with a=8.7190(5), b=8.8500(4), c=22.5953(9) Å, β=94.6290(17)°, V=1737.84(14) Å3 and Z=4. Salt 2 crystallizes in the monoclinic system space group P21/n with a=10.9328(9), b=8.1700(6), c=13.8095(11) Å, β=97.130(3)°, V=1223.94(17) Å3 and Z=4. In both salts, dialkylammonium cations and selenate anions are connected through NH···O and OH···O hydrogen bonds. In the crystal structure, 1 and 2 are organized in layer-like arrangements. Structural characterizations were …
