Legal questions on financial market abuse
2015
Purpose – The purpose of this study is to underline the impact that globalization of financial markets has on national punishment policies. The US financial crisis has strongly affected consumers’ lives, but the focus of this research is on the national provisions against the illegal and unfair behaviour of economic actors, with special regard to a phenomenon that took place abroad, but whose effects came to light in many different countries. Design/methodology/approach – Different methodological approaches, both deductive and inductive, are combined in the present paper, together with comparative and philosophical insights on national Court decisions and scholar writings. Findings – As Eu…
Can a magic recipe foster university spin-off creation?
2015
This study examines factors that explain the creation of university spin-offs. The study focuses on mechanisms that technology transfer offices (TTOs) and universities employ to foster spin-offs. These mechanisms include technology transfer activities that support spin-offs, normative frameworks, support infrastructures (i.e., business incubators and science parks), and TTO staff's specialist technical skills. The analysis also differentiates between public and private universities. Spin-offs belong to one or more of the following groups: spin-offs with support from the university's TTO, spin-offs operating under a license agreement, and spin-offs in which the TTO or university holds equity…
Bio-imaging with the helium-ion microscope: A review
2021
Scanning helium-ion microscopy (HIM) is an imaging technique with sub-nanometre resolution and is a powerful tool to resolve some of the tiniest structures in biology. In many aspects, the HIM resembles a field-emission scanning electron microscope (FE-SEM), but the use of helium ions rather than electrons provides several advantages, including higher surface sensitivity, larger depth of field, and a straightforward charge-compensating electron flood gun, which enables imaging of non-conductive samples, rendering HIM a promising high-resolution imaging technique for biological samples. Starting with studies focused on medical research, the last decade has seen some particularly spectacular …
Submicrometer-Sized Roughness Suppresses Bacteria Adhesion.
2020
Biofilm formation is most commonly combatted with antibiotics or biocides. However, proven toxicity and increasing resistance of bacteria increase the need for alternative strategies to prevent adhesion of bacteria to surfaces. Chemical modification of the surfaces by tethering of functional polymer brushes or films provides a route toward antifouling coatings. Furthermore, nanorough or superhydrophobic surfaces can delay biofilm formation. Here we show that submicrometer-sized roughness can outweigh surface chemistry by testing the adhesion of E. coli to surfaces of different topography and wettability over long exposure times (>7 days). Gram-negative and positive bacterial strains are tes…
Highly phosphorescent perfect green emitting iridium(iii) complex for application in OLEDs.
2007
A novel iridium complex, [bis-(2-phenylpyridine)(2-carboxy-4-dimethylaminopyridine)iridium(III)] (N984), was synthesized and characterized using spectroscopic and electrochemical methods; a solution processable OLED device incorporating the N984 complex displays electroluminescence spectra with a narrow bandwidth of 70 nm at half of its intensity, with colour coordinates of x = 0.322; y = 0.529 that are very close to those suggested by the PAL standard for a green emitter.

Antimicrobial Properties of the Modified Cotton Textiles by the Sol-Gel Technology
2015
Comparison of the antimicrobial properties of textiles with amorphous coatings containing Zn and Si obtained by the sol-gel technology against microorganismsPseudomonas fluorescens,Saccharomyces cerevisae,Trichoderma viridethat can cause cotton textile destruction was made. Modified textile were evaluated using scanning electron microscopy, energy dispersive x-ray spectroscopy. Investigation of antimicrobial properties of the cotton fabric samples treated with different zinc acetate dihydrate concentration sols and various thermal post-treatments was made. Strong inhibition of microbial growth was detected for all cotton textile samples treated via sol-gel method according all tests microor…
Herbal medicinal products - Evidence and tradition from a historical perspective.
2017
Abstract Background Aside from the fully licensed herbal medicines there are products on the European pharmaceutical market which are registered by virtue of their longstanding traditional use. The normal registration procedure does not apply to them because presently they do not meet the legal requirements for a full license as set out in the relevant European Union Directive. One of these requirements, “proof of tradition”, has so far been dealt with in different ways and fails to meet the criteria of good practice. Method This analysis is based on a selective literature search in PubMed and in databases of medical and pharmaceutical history, interviews with licensing experts, a consensus…

Abatement of AO7 in a divided microbial fuel cells by sequential cathodic and anodic treatment powered by different microorganisms
2017
Abstract Microbial fuel cells (MFCs) can allow the treatment of organic pollutants resistant to conventional biological processes by electro-Fenton (EF) process performed in the cathodic compartment. However, EF usually results in a partial mineralization of pollutants. Here, we have studied the possible treatment of such organics in a MFC by a sequential cathodic and anodic treatment. In particular, the treatment of an aqueous solution of Acid Orange (AO7), a largely used azoic dye resistant to conventional biological processes, was performed in the cathodic compartment of a divided MFC by EF. The process allowed the total removal of the color and the partial removal of the TOC, due mainly…
