1. Monolith Reactors in Three-Phase Processes
Abstract : The use of monoliths in chemical processes has been studied with the emphasis on liquid-phase hydrogenations. A monolithic catalyst consists of many narrow, parallel channels with catalytically active species either incorporated into the wall itself or into a layer of a porous oxide deposited on the wall (a washcoat).

2. Combinatorial Optimization : Three Applications
Abstract : Combinatorial optimization is a diverse area of mathematics. It concerns optimization on feasible regions defined by discrete sets, graphs, hypergraphs, matroids, etc. . . READ MORE

3. Catanionic Surfactant Mixtures and Binary Systems of Modified Fatty Acid Surfactants. Phase Equilibria and Structure
Abstract : Surfactant self-assembly is an important phenomenon that occurs in a number of processes in our everyday life. It is important to understand the forces and parameters that control and influence the self-assembly, as this knowledge can be used both in order to design surfactant systems with desired properties and for creating model systems, for example for biological processes.

4. High-resolution biomedical phase-contrast tomography
Abstract : Improved three-dimensional biomedical imaging can give a better understanding of tissue structure, growth and diseases. Most present imaging techniques that provide cellular spatial resolution are based on visible or infrared light. These methods cannot image deeper than a millimeter into tissue. READ MORE

5. Flash Diffractive Imaging in Three Dimensions
Abstract : During the last years we have seen the birth of free-electron lasers, a new type of light source ten billion times brighter than syncrotrons and able to produce pulses only a few femtoseconds long. One of the main motivations for building these multi-million dollar machines was the prospect of imaging biological samples such as proteins and viruses in 3D without the need for crystallization or staining.
