Book Description
All real solid surfaces are heterogeneous to a greater or lesser extent and this book provides a broad yet detailed survey of the present state of gas adsorption. Coverage is comprehensive and extends from basic principles to computer simulation of adsorption. Underlying concepts are clarified and the strengths and weaknesses of the various methods described are discussed. - Adsorption isotherm equations for various types of heterogeneous solid surfaces - Methods of determining the nature of surface heterogeneity and porosity from experimental data - Studies of phase behavior of gases absorbed on heterogeneous solid surfaces - Computer simulation of adsorption on heterogeneous solid surfaces

Book Description
Fundamentals of Adsorption is the proceedings of the fifth International Conference on the Fundamentals of Adsorption, which was held on May 13-18, 1995 at the Asilomar Conference Center, Pacific Grove, California. This conference was organized completely under the auspices of the International Adsorption Society. It was attended by 196 participants from 24 countries. Members of the Scientific Advisory Board, together with the Conference Committee, selected papers for presentation from a large number of proposals involving an especially high level of international participation. The fundamental aspects of adsorption is a subject which has grown rapidly in recent years, drawing researchers from many disciplines including materials science, chemistry, physics, biochemistry and biotechnology, and chemical, civil, mechanical and environmental engineering. Fundamentals of Adsorption serves as an excellent reference and may be used as a primary text for a graduate level course on adsorption research or as a secondary text for a course on any of the disciplines mentioned above.

Book Description
The knowledge of behavior of liquids with free surfaces to their surrounding gaseous phase in compensated gravity is essential to the development of tank systems for spacecrafts. In microgravity, the liquid behavior is dominated by capillary forces, which are used to position and redistribute liquid propellant in a desired way for the mission. The body forces occurring due to residual accelerations, which can be caused by spin during the ballistic flight phases, force the liquid to reorient towards a new equilibrium state of the free surface. Due to spin the liquid is driven away from the tank outlet and located along tank walls in partially filled tanks. To assure enough liquid fuel over the tank outlet, so-called Propellant Management Devices (PMD’s), are employed. A PMD is a static, usually metal structure, which either provides a passage way for a liquid in microgravity or stores a certain amount of liquid at a desired location. Some PMD’s are designed to be refillable in periods of microgravity due to openings in the outer housing or by a housing composed of perforated metallic sheets. These reservoirs are refilled in periods of compensated gravity in order to provide the required amount of liquid fuel for attitude control or other maneuverings. Relatively large disturbances, such as lateral accelerations and spin, can drive the liquid fuel out of the reservoir, resulting in malfunction of the device. During spilling, gas enters the device such that only a residual amount of liquid propellant can be kept in the reservoir. Moreover, the connection to the bulk liquid in the tank may be interrupted such that refilling of the reservoir is disrupted. Hence, a PMD with two parallel disks forming the inlet and a venting tube at the topmost point of the outer housing shall be designed such that its refillable structure is only filled with liquid without any gas or vapor being easily trapped during operations.
