Orgoglio poetico e lode della patria nelle epistole di Girolamo Muzio al nipote Maurizio
2020
L’Egida, poema in endecasillabi sciolti composto da Girolamo Muzio fra il 1570 e il 1572 e pervenutoci incompleto, celebra le antiche vicende della terra d’Istria e, in particolare, della città di Capodistria (anticamente denominata Egida). Muzio difende il suo poema in alcune lettere indirizzate al nipote Maurizio nel 1575, nelle quali controbatte punto per punto le riserve sul poema formulate dai letterati di Capodistria. Quest’intervento si propone di rileggere tali epistole di Muzio, con lo scopo di evidenziare, in esse, l’orgoglio poetico professato chiaramente dallo scrittore e il suo attaccamento alla terra d’elezione, da lui sempre lodata ed esaltata. Queste epistole, inoltre, sono …
Supramolecular functionalization and concomitant enhancement in properties of Au25 clusters
2014
We present a versatile approach for tuning the surface functionality of an atomically precise 25 atom gold cluster using specific host-guest interactions between ?-cyclodextrin (CD) and the ligand anchored on the cluster. The supramolecular interaction between the Au25 cluster protected by 4-(t-butyl)benzyl mercaptan, labeled Au25SBB18, and CD yielding Au25SBB18�?�CDn (n = 1, 2, 3, and 4) has been probed experimentally using various spectroscopic techniques and was further analyzed by density functional theory calculations and molecular modeling. The viability of our method in modifying the properties of differently functionalized Au25 clusters is demonstrated. Besides modifying their optoe…

COMPARISON OF CRIMSON FOUNTAINGRASS AND DISS FIBRES AS AGGREGATES FOR CEMENT MORTARS
2019
The use of natural fibres in cement composites is an expanding research field as their use can improve the mechanical and thermal behavior of cement mortars and reduce their carbon footprint. In this paper two different wild grasses, i.e. Pennisetum Setaceum, also known as crimson fountaingrass, and Ampelodesmos Mauritanicus, also called diss, are used as source of natural fibres for cement mortars. The principal aim is to evaluate the possibility of using the more invasive crimson fountaingrass in place of diss inside cement based vegetable concrete. The two plants’ fibres have been characterized by means of electron microscopy, helium picnometry; moreover, the thermal conductivity of fibr…
Brief an Garlieb H. Merkel
1798
Ms. 930a, Nr. 10, Bl. 26r-28v Schmidt-Phiseldeck, Konrad von. Brief an Garlieb H. Merkel, Kopenhagen, am 6. März 1798 Autora rokraksts / Autograph, vācu un latīņu val. / Deutsch und Latein [6] lpp. / S. Attēlu numuri / Bildnummern: 930a-010-1 – 930a-010-6 Der Verfasser äußert zum Beginn seines Briefes erneut sein Bedauern über die räumliche Trennung und wünscht sich, nach Italien zu reisen. Weimar, wo Merkel zum gegebenen Zeitpunkt wahrscheinlich weilte, glorifiziert Schmidt-Phiseldeck mit der Bezeichnung als „Weimar-Athen“. Gleichzeitig drückt der Verfasser seine Enttäuschung über die Politik Frankreichs bezüglich der Schweiz aus, erkennt aber in der Neutralität seiner neuen Heimat Dänemar…

Dual drug-loaded halloysite hybrid-based glycocluster for sustained release of hydrophobic molecules
2016
A dual drug-loaded HNT–CD glycocluster delivery system based on halloysite nanotubes and carbohydrate functionalized cyclodextrin was developed by a green protocol using solvent-free microwave irradiation. The nanohybrid was employed for concurrent load and release of silibinin and curcumin. The new delivery system was characterized by means of TGA, FT-IR spectroscopy, SEM and DLS. These techniques confirm the successful loading of the two drugs in the system. SEM and DLS measurements highlighted that the nanomaterial preserves a tubular structure with an average hydrodynamic radius of ca. 200 nm. The release of the drugs from the HNT glycocluster was investigated by means of UV-vis spectro…
pH-Responsive Cyclodextrin-Surfactant Inclusion Complexes: Thermodynamics and Structural Aspects
2023
This thesis presents the investigation of the multilevel assembly of the alkyl oligoethylenoxide carboxylic acids and cyclodextrins. The aim of the work is to combine the short-range host-guest and long-range electrostatic interactions to form highly-ordered supramolecular complexes. The interactions between the components affect their individual response and their properties; therefore, the knowledge of the nature and the influence of their chemical structure is essential to understand the system’s behaviour. Polyoxyethylene alkyl carboxylic acids are an attractive class of surfactants to integrate both inclusion complexes and polyelectrolyte systems due to their pH and thermoresponsivenes…
Über Phosphor‐haltige Heterocyclen I. Kristallstruktur von trans ‐1,6‐Diphenyl‐1λ 5 ,6λ 5 ‐diphosphacyclodecan‐1,6‐dion‐Dihydrat
1974
Die Struktur der Titelsubstanz (2) wurde rontgenographisch bestimmt und bis zu einem konventionellen R von 0.039 verfeinert. 2 ist zentrosymmetrisch. Der 10-Ring besitzt die bei Cyclodecan-Derivaten (3) ubliche Konformation niedrigster Spannungsenergie. 2 und 3 haben vergleichbare Pitzer- und Baeyer-Spannung, die transannularen Wechselwirkungen sind jedoch in 2 verringert. Die geminalen Phenyl- und Oxo-Substituenten stehen beide extra-annular (Phenyl trans-pseudoaxial, Oxo trans-pseudoaquatorial). Mittlerer CP-Abstand 1.804(3) A, PO-Abstand 1.502(3) A. Die Struktur besteht aus uber PO…HOH…OP-Wasserstoffbrucken verbundenen 2-Molekulen. On Heterocyclic Systems Containing Phosphorus, I. Crysta…
