Recent evidence suggests that circadian clocks ensure temporal orchestration of lipid homeostasis and play a role in pathophysiology of metabolic diseases in humans, including type 2 diabetes (T2D). Nevertheless, circadian regulation of lipid metabolism in ...

For many diseases, where a particular organ is affected, chemical by-products can be found in the patient's exhaled breath. Breath analysis is often done using gas chromatography and mass spectrometry, but interpretation of results is difficult and time-co ...

The interface between two immiscible electrolyte solutions (ITIES) provides a well-defined platform for fundamental studies of adsorption processes and molecular reactivity in general. Two bio-inspired systems are considered in the present work: adsorbed p ...

The work presented in this thesis was carried out in the framework of two European projects: SOLWATER, and AQUACAT. The global objective of those projects, including the present work, was to set an autonomous system for drinking water production in develop ...

Low temperature co-fired ceramic (LTCC) technology has attracted remarkable attention in fabrication of sensors and micro-fluidic devices in the last decade. Although structuring planar LTCC foils, which are processed and screen-printed with thick-films, s ...

Organophosphorus compounds found applications in varied fields of the organic chemistry: they are particularly present in natural compounds such as the deoxyribonucleic acid (DNA) and in the field of catalysis in which their utility is also proven. Thus, t ...

Since a few decades, the balance of the nitrogen (N) cycle has been deeply disturbed by human activies. The global impact of these activities on the N cycle can be described as a doubling of the transfer from the vast and unreactive atmospheric pool to bio ...

Cell-membrane sheets suitable for in-vitro functional fluorescence studies have been prepd. by direct detachment from cell membranes using poly-L-lysine-coated glass slides. The resulting transferred planar membranes conserve the compn. as well as most pro ...

This work describes the advancements made in micro and nano patterning via stencil lithography. Stencil lithography is a resist-less and direct pattern technique where a controlled amount of material is deposited through apertures on to a substrate in a va ...

Supported cell-membrane sheets are promising in vitro systems to investigate the properties of membranes with native protein/lipid composition, in particular their sub-compartmentalization and the differential localization of proteins associated to them. W ...

Oxygen permeability through the tubular La0.7Ca0.3Fe0.85 Co0.15O3-δ perovskite membrane prepared by thermoplastic extrusion was measured in the temperature range from 800° to 1040°C in an air/argon gradient, and compared with the oxygen permeability of pla ...

The influence of partial substitution of Fe with Ti on the oxygen transport properties of La1- xSrxFeO3 membranes was investigated in view of their application for oxygen separation. Samples of composition La0.5Sr0.5 Fe1-yTiyO3-δ (y = 0, 0.2) were prepared ...

In this communication, we report on an interesting observation of wide-ranging potential for cellular imaging and manipulation: Hydrophobic QDs can be easily incorporated into the bilayer membrane of lipid vesicles. Such lipid/QD nanocontainer hybrid vesic ...

The central goal of this thesis work is to fabricate novel, functional fluorescent nanostructures in confined systems offered by phospholipid membranes, which are known to have highly ordered, thermotropic and lyotropic structures. In separate approaches, ...

Composting (aerobic treatment of organic wastes) and digestion (anaerobic treatment of organic wastes combined with biogas production) are important waste management strategies with increasing significance in the European Union and Switzerland. Most of the ...

Neutral metallamacrocycles with four or ten metal centers were obtained by reaction of [(R3P)PdCl2]2 with 2,3-dihydroxypyridine and derivatives or 2-hydroxynicotinic acid in the presence of base. In all these assemblies, the two O-donor atoms of the ligand ...

Only with appropriate coatings and coating techniques the use of nanoparticles is possible for biomedical applications. The appropriate choice of the coating material and techniques helps to render the particles biocompatible, colloidally and chemically st ...

Organic–inorganic hybrid materials were prepared using the sol–gel process in order to improve the scratch resistance of poly(methyl methacrylate) (PMMA) substrates. Sol–gel solutions based on tetraethoxysilane and α,ω-triethoxysilane terminated polycaprol ...

An experimental setup to study the pH dependence of standard ion-transfer potentials at the water/NPOE interface is presented. The system is composed of a micro-hole generated by laser photoablation in a 12-μm polyethylene terephthalate film, the aqueous p ...

Despite the importance of trafficking for regulating G protein-coupled receptor signaling, for many members of the seven transmembrane helix protein family, such as odorant receptors, little is known about this process in live cells. Here, the complete lif ...
