Energy conversion at liquid/liquid interfaces: artificial photosynthetic systems

This chapter focuses on multielectron reactions in organized assemblies of molecules at the liquid/liquid interface. We describe the thermodynamic and kinetic parameters of such reactions, including the structure of the reaction centers, charge movement along the electron transfer pathways, and the role of electric double layers in artificial photosynthesis. Some examples of artificial photosynthesis at the oil/water interface are considered, including water photooxidation to the molecular oxygen, oxygen photoreduction, photosynthesis of amphiphilic compounds and proton evolution by photochemical processes.     

Modified poly(ethyleneimine) supports for vanadium,molybdenum, and rhenium removal

Summary The solution behaviour of the polycarboxylic acid derived from scleroglucan (sclerox) has been investigated as a function of NaOH concentration and temperature by means of polarimetry and viscosimetry techniques. In comparison to the native polymer, sclerox is less sensitive to degradation at high NaOH concentration (up to NaOH equal to 0.4 M) and thermally more stable. The viscosity data show a normal polyelectrolyte effect and the polymer chains seem to be not stiff. We conclude that at high pH sclerox chains are in a flexible, probably single stranded conformation.     

Simple autocollimation laser refractometer with highly sensitive, fiber-optic output

A simple autocollimation scheme for a laser refractometer with a highly sensitive, single-mode, fiber-optic output is described. It allows for the determination of the refractive index and dispersion of optical materials with an accuracy exceeding 10(-5), which is confirmed by both experimental and analytical investigations.     

Electronic speckle interferometry, phase-mapping, and nondestructive testing techniques applied to real-time, thermal loading

A digital phase-mapping method has been developed for application in real-time electronic speckle interferometry studies. Its principles and application to a continuously deforming object are described. An efficient digital image-processing algorithm has been developed that permits quantitative interpretation of the resulting phase maps.     

Ultraviolet-visible spectrograph optics: ODIN project

We describe one of the possible designs for the UV-visible spectrograph optics to be employed in the ODIN project. The spectrograph will be used in a future satellite mission for aeronomy observations and will image a column of atmosphere just above the Earth's surface onto a two-dimensional CCD array with the spatial and spectral content aligned orthogonal to one another.
