Two water-insoluble forms of urokinase have been prepared by coupling the enzyme to two different carriers: one electrostatically neutral (Enzacryl), the other polyanionic (a polymer of maleic anhydride and ethylene). The solid-phase urokinases act on their physiological substrate, human plasminogen....
In other words, the surface system forms an independent two-dimensional superfluid that, at the zero-temperature limit, determines the thermo-mechanical properties of 3He. Confining a fermion gas at a low temperature to a high-purity two-dimensional solid-state system has led to the discovery ...
2. Virtually all important properties of solid materials may be grouped into six different categories:mechanical,electrical,thermal,magnetic,optical,and deteriorative 实际上,固体材料的所有重要材料可以被分成六个目录,力学,热学,磁学,光学和失效。 3. In addition to structure and properties, two other impo...

opened bandgap. Here, we cover the recent state of the art in the field of monoelemental 2D materials preparation using “bottom-up” approach together with discussion of possible future directions in material preparation. The review cover also the properties and some theoretical aspects of synthesis...
