章节摘录
版权页： 插图： Many years of experimentation with diverse crystals has confirmed the notion that,by minimizing convective mass transport,better quality crystals can be obtained,with improved mechanical and optical properties,re-duced density of defects,and larger size. How is it possible to suppress the natural convection in crystallogenesis?Nowadays,different approaches have arisen for removing or at least reducing it.One of them is crystallization of macromolecules in space,where in the absence of gravity,convection disap-pears.In the last decade,a new approach that involves the use of magnetic fields has appeared.Magnetic forces opposed to gravity can reduce natural convec-tion inside solutions [47.31,32].Also,methods for crystallizing macromolecules in gels are good and well-accepted alternatives for eliminating natural con-vection [47.33]. It is natural to think that,at zero or reduced gravity,crystals with superior properties can be grown [47.18].Is this possible?Observations and experimental data support the hypothesis that convective flows can be related to the introduction of statistical disorder,defects,and dislocations on growing crystal sur-faces [47.34-36].Convective transport tends to be variable and random,producing variations in the super-saturation levels in the environment of the developing faces,exposing them permanently to high levels of nu-trients,similar to those of bulk crystallization.On the contrary,under microgravity,convection is suppressed and the concentration of nutrients at the interface of the crystal is reduced.Mass transport is purely diffusive,which for proteins is very slow,and a region of de-pletion of nutrients is established around the nucleus.Thanks to the absence of gravity,this zone is qua-sistable.We can imagine one crystal in the center and the gradient of nutrients on the right-hand side and on the left-hand side aggregates and large impurities.
