    Description / Table of Contents: Riassunto Si è misurato il coefficiente di assorbimento acustico in una soluzione all' 1% di lisozima, a frequenze comprese tre 5 e 50 MHz, in funzione del tempo. Dalle misure fatte è evidenziato un processo di rilassamento, dovuto al movimento di diffrazione dei cluster. Tale processo va gradualmente spegnendosi allorché i cluster interagenti si uniscono in una struttura tixotropica. I risultati ottenuti sono discussi in termini di un modello già proposto in base a precedenti esperimenti di misure di viscosità e diffusione di luce.
    Abstract: Резюме Измеряется коэффициент акустического поглощения в 1% w/w растворе лизоцима в области частот от 5 до 50 МГц, как функция времени. Показывается, что имеет место процесс релаксации, обусловленный диффузионным движением кластеров. Такой процесс релаксации постепенно затухает, когда взаимодействующие кластеры образуют тиксотропную структуру. Полученные результаты обсуждаются в рамках общей модели, предложенной ранее на оснобе экспериментальных измерений вязкости и рассеяния света.
    Notes: Summary The acoustic-absorption coefficient is measured in a 1% w/w lysozyme solution, at frequencies ranging from 5 to 50 MHz, as a function of time. It is shown that a relaxation process due to diffusional motion of clusters exists. Such a process is gradually quenched, as the interacting clusters become fixed in a thixotropic solidlike structure. The obtained results are discussed in the frame of a general model early proposed on the basis of viscosity and light scattering experiments.

    Description / Table of Contents: Riassunto Si riportano gli effetti di alcoli monoidrici sulle proprietà tixotropiche di una soluzione di BSA (1% in peso). La presenza degli alcoli nella soluzione, anche a piccole concentrazioni, indebolisce la struttura che origina le proprietà tixotropiche. Tale effetto cresce al crescere della concentrazione alcoolica e con le dimensioni dei gruppi alchilici. Si presentano altresí evidenze indirette che collegano gli effetti osservati con un’alterazione delle interazioni idrofobiche causate dagli alcoli.
    Notes: Summary We report on the effects of monohydric alcohols on the thixotropic properties of a 1% (by weight) BSA solution. The presence of alcohols in the solution medium, even in very small amounts, weakens the structure responsible for the thixotropic properties: this effect increases with increasing alcohol concentration and alkyl group size. We also present indirect evidence relating the observed effects to the alteration, in the presence of alcohols, of protein-solvent hydrophobic interactions.

    Description / Table of Contents: Riassunto Nel presente lavoro si discutono i risultati di misure EXAFS e Raman in miscele di elettroliti forti (ZnBr2, CuBr2, SrBr2) in H2O. Le misure EXAFS, eseguite presso i laboratori PULS di Frascati, e le misure di spettroscopia Raman, eseguite presso i nostri laboratori di scattering di luce, ci hanno permesso di studiare sia la statica che la dinamica di questi sistemi. In particolare, si evidenziano le formazioni di coppie ioniche metallo-alogeno e di sfere d’idratazione. I risultati sono discussi in termini dei già esistenti modelli strutturali.
    Abstract: Резюме В этой работе обсуждаются спектры EXAFS и рамановские спектры, полученные в смесях сильных электролитов (ZnBr2, CuBr2, SrBr2) в воде. Измерения проводились на ADONE в фраскати для измерения EXAFS и в лаборатории рассеяния света для измерения рамановского рассеяния. Результаты измерений дают информцию о статических и динамических свойствах этих систем. В частности, обнаружено образование ионных пар металл-галоген и областей гидратции. Полученные результаты обсуждаются в рамках существующщих структурных моделей.
    Notes: Summary EXAFS and Raman spectra, obtained from mixed MBr2+NBr2 (M, N=Zn2+, Cu2+, Sr2+) in H2O are discussed. The measurements, carried out at Adone (PULS facility), for EXAFS and in our light scattering laboratory, for Raman, allow us to study both the static and the dynamic properties of these systems. In particular, strong evidence of metal-halogen ionic pairs and hydration shell formation is reported. Our results, in terms of existing structural models, are also discussed.
