• Homepage of Dr. Iwanowski: Microgravitation Physics

    Everything on Earth is subject to the forces of gravity. Their effects may vary a lot: sometimes they are weak and go largely unnoticed, sometimes they are obvious. When it comes to scientific investigations, gravity can sometimes prove to be a nui- sance, or, conversely, scientists may be interested to know what would happen without its influence. To study such effects, scientists want to experiment in microgravity

    Excimer laser are gas lasers, which can generate electromagnetic radiation in the ultraviolet wavelength range. Application examples are the surgical correction of myopia, the photolithography for the manufacture of highly integrated semiconductor devices or micro-machining (the "drilling" extremely fine nozzles for inkjet printers). A new prominent application of excimer laser can be find in the annealing technology. “The first commercial excimer laser was built by Lambda Physik in 1977 (Göttingen)”.

    The Bhattacharjee-Ferrell theory and the crossover theory nicely represent the experimental ultrasonic attenuation data as well as the shear viscosity and dynamic light scattering data. This is true for binary and also for ternary mixtures. Experimental critical exponents agree with those from theory. There is, however, a necessity for the development of new theories treating the coupling between chemical relaxations and critical fluctuations.

    General relativity is a beautiful scheme for describing the gravitational field and the equations it obeys. Nowadays this theory is often used as a prototype for other, more intricate constructions to describe forces between elementary particles or other branches of fundamental physics
