Ionizing radiation in general and mixed fields of space radiation in particular pose a risk of serious harm to human health. The risk of such adverse effects increases with the duration of the mission, and for all missions outside the protective prop

Dynamic light scattering (DLS) is a well-known noninvasive technique for investigating interactions of protein molecules in solution. Unfortunately, DLS is not very sensitive to small size changes because covariables, such as temperature, viscosity,

A means of controlling crystallization is to separate the phases of nucleation and growth. Methods to achieve this, other than seeding, involve lowering the supersaturation by changing the temperature or diluting drops after incubating them for a giv

Dynamic light scattering (DLS) measurements were conducted with lowest intensity levels on human eye lenses (3.2 mW/cm2) within measurement times of 3-5 s. A characterisation of the human eye under in-vivo conditions along the optical axis is given a

We used Dynamic Light Scattering to study bio-molecule samples flown on the STS-95 mission, and processed in the Advanced Protein Crystallization Facility. The data represent for the first time characteristics of samples, which have been investigated

Instruments based on photon counting in the visible part of the spectrum with subsequent signal autocorrelation of the light intensity fluctuation are widely used for the characterization of clear media, but are performance limited if multiple scatte

Laser light source powers of our instrument LEPOSIAR are minimized so that dynamic light scattering (DLS) measurements can be conducted with lowest intensity levels on human eye lenses (3.2 mW/cm2) within measurement times of 3 to 5 seconds. We descr

Time averaged static light scattering (SLS) intensity collections on suspensions with defined particle dimensions and concentrations were achieved by utilization of the Zeiss SG 100 goniometer scatterometer. The bidirectional straylight distribution

In course of instrumentation technology developments for spaceborne experiments under microgravity in areas of nucleation control during crystal growth and critical point phenomena, miniaturized optrodes were achieved. Described optrodes can be easil
