Synthesis, characterization and self-assembly of three dicyanamide bridged polynuclear copper(II) complexes with N2O donor tridentate Schiff bases as…

2016

Three copper(II) complexes [Cu(L1)(μ1,5-dca)]n (1), [Cu(L2)(μ1,5-dca)]n (2) and [Cu(L3)(μ1,5-dca)]n (3) [where HL1 = (1-(2-(dimethylamino)ethylimino)ethyl) naphthalene-1-ol, HL2 = (1-(2-(methylamino)ethylimino)ethyl) naphthalene-1-ol and HL3 = (1-(2-(ethylamino)ethylimino)ethyl)naphthalene-1-ol] have been synthesized and characterized by elemental analysis, IR and UV–Vis spectroscopy. The structure of each complex has been confirmed by single-crystal X-ray diffraction studies. In all three complexes, copper(II) centres are bridged by dicyanamide in end to end fashion. Complexes 1 and 2 are zigzag polymers, whereas complex 3 is a helical one. The weak forces like C–H⋯π and π⋯π interactions i…

Preparation of potentially porous, chiral organometallic materials through spontaneous resolution of pincer palladium conformers.

2013

Understanding the mechanism by which advanced materials assemble is essential for the design of new materials with desired properties. Here, we report a method to form chiral, potentially porous materials through spontaneous resolution of conformers of a PCP pincer palladium complex ({2,6-bis[(di-t-butylphosphino)methyl]phenyl}palladium(II)halide). The crystallisation is controlled by weak hydrogen bonding giving rise to chiral qtz-nets and channel structures, as shown by 16 such crystal structures for X = Cl and Br with various solvents like pentane and bromobutane. The fourth ligand (in addition to the pincer ligand) on palladium plays a crucial role; the chloride and the bromide primaril…

Synthesis and self-assembly of a PEGylated-graphene aerogel

2016

Abstract In the frame of this work, we present, for the first time, the synthesis and self-assembly of an aerogel built by graphene oxide-polyethylene glycol. The synthetic route involves at first the coupling of GO with an amino-terminated polyethylene glycol sample by carbodiimide in aqueous environment, and the subsequent conversion of the hydrogel achieved into an aerogel via freeze-drying. The 3D PEGylated graphene-based aerogel, characterized by spectroscopic, morphological, structural and mechanical analyses, displays an ultralight and highly porous (99.7%) network and possesses high mechanical properties together with a good biocompatibility.

FEHLERHAFTE HAUPTVERSAMMLUNGSBESCHLÜSSE IM ITALIENISCHEN GESELLSCHAFTSRECHT Anlässe für die deutsche Reform?

2012

Fehlerhafte Hauptversammlungsbeschlüsse im Italienischen Gesellschaftsrecht. Anlässe für die deutsche Reform?, liberamente traducibile "L'invalidità delle delibere assembleari nel diritto italiano. Spunti per la riforma del diritto tedesco?", riproduce - con qualche variazione e l'aggiunta di due appendici normative bilingue - un saggio scritto nel 2010 nel contesto di una ricerca che il Ministero della Giustizia della Repubblica federale tedesca ha affidato al Max-Planck-Institut für ausländisches und internationales Privatrecht di Amburgo, che apparirà nel 2013 per i tipi dell'editore Mohr-Siebeck di Tubinga. La ricerca è stata concepita, fin dall'inizio, in funzione del giurista tedesco …

Applications of DNA self-assembled structures in nanoelectronics and plasmonics

2018

In this thesis, the potential applications of DNA self-assembled structures were explored in both nanoelectronics and plasmonics. The works can be divided into two parts: electrical characterization of unmodified multilayered DNA origami and DNA-gold-nanoparticle conjugates after they were trapped between gold nanoelectrodes by dielectrophoresis, and the development of a novel fabrication method using DNA origami as a template for smooth, high resolution metallic nanostructures as well as optical characterization of them. One of the biggest challenges in self-assembled nanoelectronic devices is to connect them to macroscopic circuits. Dielectrophoretic (DEP) trapping has been used extensivel…

DNA-based applications in molecular electronics

2011

This thesis is mainly focused on DNA molecules and especially on self-assembled DNA constructs and their potential applications in nanotechnology and molecular electronics. In the field of molecular electronics the conductivity of DNA is a crucial - yet open - question, and it is of great concern, since DNA is a very promising molecule in a context of bottom-up based nanodevices due to its superior selfassembly characteristics. A key tool in all the experiments presented in this thesis is a dielectrophoretic trapping technique, which was exploited in spatial manipulation of individualDNA molecules, DNA constructs and also semiconducting quantum dots. In the case of DNA, the technique provid…

Heterogeneity in Disordered Gambling: Decision-Making and Impulsivity in Gamblers Grouped by Preferred Form

2019

Background: Previous research has indicated that disordered gamblers display deficits in impulsivity and risky decision-making, compared to healthy control groups. However, disordered gamblers are not a homogenous group, and differences in performance on neurocognitive tasks may be related to the form of gambling in which an individual chooses to engage. The present study used neurocognitive tasks and questionnaire measures to ascertain group differences in gamblers grouped by preferred form of gambling. Method: Treatment-seeking pathological gamblers from the National Problem Gambling Clinic, London (n = 101), completed a neurocognitive assessment comprising the Cambridge gamble task (CGT)…
