Integration of these materials into working devices
requires precise control of surface properties.
These GXL properties allow tuning of liquid properties by inclusion of high pressure gases.
All other samples displayed an increase in dielectric constant by factors of 5-10, although sample thicknesses (~600 nm) and water contact angles were essentially constant before and after processing.
These studies suggest that photoresist and etch residue can be removed from low k MSQ films with GXLs without degradation of film properties, provided that a final high pressure CO2/CH3OH rinse is invoked for MSQ property recovery.
We demonstrated that moderate pressure liquids such as TMAHCO3/CH3OH expanded by CO2 (GXLs) can be used to effectively remove photoresist and plasma etch residues without significant degradation of low film properties, although a high pressure CO2/CH3OH rinse is required in order to fully recover the low k film properties.

This change in process induces microstructure
changes, which by its turn influence the mechanical properties of the slab [4].
Two factors can be used to reduce the effects of rolling the as cast microstructure.
Another factor is the cooling rate during solidification, which can reach values above 1.9 o C/s, due the small thickness slab [9].
The application of thickness reduction affects the secondary dendrite arm spacing.

When a time-dependent nonuniform mechanical load is applied to the fluid-filled bone, the
interstitial fluid flow occurs through the interconnected pore space in bone.
In general, SGP is affected by a viscosity of bone fluid, flow rate, and interstitial pressure distributions.
Furthermore, it could be one of important factor inducing bone remodeling processes.
The interstitial fluid pressure generation characteristics in bone are functions of its poroelastic properties and boundary conditions.
The mostly important factors governing the interstitial fluid flow are the fluid and loading boundary condition.

-%Si) is important for the electrical industry because of
its magnetic properties.
Such combination of properties allow for achieving low electrical losses, due to Eddy current and hysteresis cycles, especially at high frequencies [1].
Compression tests at room temperature (RT) were carried out in order to study the deformation behavior in function of the previous thermomechanical treatment: cooling rate after hot rolling, effect of the annealing temperature and effect of delay at room temperature (time between the end of the cooling down to room temperature and the start of the cold deformation) on mechanical properties.
Samples with higher Si content can show a retardation factor of 55 compared to low silicon samples at 800°C [5].

In order to improve the mechanical properties, the principle of Accumulative Roll-Bonding (ARB) [1] has been adopted and investigated on a wide range to magnesium alloys in the recent years [2-12].
Therefore, an investigation of influence factors on bonding strength for Mg-Mg composite roll-bonding within an ARB-process has been started.

In the case of bismuth telluride based materials, that have a layered structure and can be easily cleaved along these layers, the use of polycrystalline materials improves their mechanical properties.
Recently the factors affecting the quality of obtained samples were studied in [9, 10] and can be divided, following [9], into thermal (e.g., high heating rates, high local and macroscopic temperature gradients) and athermal ones (e.g., electromigration, electroplasticity, dielectric breakdown, etc.).
One of the important factors is the Joule heating.
The simulations showed that the increase of hs by factors of 2 and 4 leads to the change of the average sample temperature from 519oC to 567 and 656oC correspondingly.

However, localization of the initiation
sites on the surface affects not only the polymerization kinetics, but also determines to a remarkable
extent the chemical composition, structure and the physical properties of the resulting polymers.
This in turn determines the overall properties of the heterogeneous polymer system.
The results of investigating the influence of various factors on the molecular weight (MW) of polymers obtained (Table 2) have shown that the polymer MW and, correspondingly, degree of polymerization (DP) decrease with increasing temperature and increasing [I], which is typical to free-radical polymerization.
Influence of various factors on the molecular weight of the resulting polymers.
It has been established that the pigment surface participates not only in chain transfer reactions, but also affects all other elementary stages of polymerization.
