Industrial Biotechnology Conservation Processes: Similarities with Natural Long-Term Preservation of Biological Organisms

Corinne Scaletta, Philippe Abdel Sayed, Nathalie Hirt-Burri, Alexis Laurent

Cryopreservation and lyophilization processes are widely used for conservation purposes in the pharmaceutical, biotechnological, and food industries or in medical transplantation. Such processes deal with extremely low temperatures (e.g., -196 degrees C) a ...

Effect of ZnO on the reactivity of cementitious systems

Andrea Eloisa Teixeira Pita

One of the biggest driving forces in cement research today is the mitigation of the CO2 emissions caused by its production. A potential solution to reduce the environmental impact is to replace cement with supplementary cementitious materials (SCMs). This ...

Miniaturized Sample Preparation for Transmission Electron Microscopy

Henning Paul-Julius Stahlberg, Anastasia Syntychaki

Due to recent technological progress, cryo-electron microscopy (cryo-EM) is rapidly becoming a standard method for the structural analysis of protein complexes to atomic resolution. However, protein isolation techniques and sample preparation methods for E ...

Non-destructive 3D characterization of concrete alteration by X-ray micro-CT and correlation with petrographic and geotechnical properties

Pascal Turberg, Lukas Baumgartner, Barbara Noémie Lengyel

Concrete is a most important geomaterial as it is used for a large part in our buildings and infrastructures. According to Planetoscope (2012) its production is about 6 billion m3 per year (190 m3 each second) which makes it the most used manufactured mate ...

A spinning thermometer to monitor microwave heating and glass transitions in dynamic nuclear polarization

Geoffrey Bodenhausen, Sandrine Gerber, Pascal Miéville, Sami Jannin, Marc Anthony Caporini

As previously demonstrated by Thurber and Tycko, the peak position of Br-79 in potassium bromide (KBr) allows one to determine the temperature of a spinning sample. We propose to adapt the original design by using a compact KBr tablet placed at the bottom ...

Biomechanical analysis of cerebral arteries

Edouard Fonck

The intent of this thesis is to study the function of elastin in cerebral arteries, its contribution into the aging process and its implication into different cerebral diseases and in particular cerebral aneurysms. As of today, little is known on the genes ...

Human muscular fetal cells: a potential cell source for muscular therapies

Dominique Pioletti, Corinne Scaletta, Nathalie Hirt-Burri

Myoblast transfer therapy has been extensively studied for a wide range of clinical applications, such as tissue engineering for muscular loss, cardiac surgery or Duchenne Muscular Dystrophy treatment. However, this approach has been hindered by numerous l ...

Low stress acrylated hyperbranched polymers

Lars Schmidt

The objective of this study was to investigate the behavior of highly functional acrylates, during isothermal ultraviolet (UV) curing. The materials included a pentafunctional acrylate and two acrylated hyperbranched polymers, one with a stiff polyester co ...

Influence of Chemical Composition on the Rheological Behavior of Condensation Reaction Resins

In this paper, the chemorheological and dynamic mechanical behavior of melamine-formaldehyde (MF) resins of four different formaldehyde/melamine (F/M) molar ratios (1.25, 1.5 1.75 and 2.00) are investigated. MF resins polymerize via a polycondensation reac ...

Low-temperature electron microscopy for the study of polysaccharide ultrastructures in hydrogels. I. Theoretical and technical considerations

Urs von Stockar, Ian William Marison, David Serp

The high-pressure freezing (HPF) technique was applied to the cryo-immobilization of alginate gels and the quality of the freezing analyzed on a TEM by comparison of the segregation pattern of samples of decreasing thickness. Dynamic simulations of heat tr ...
