Le faisceau ionique focalisé permet d’obtenir une surface d’analyse très plane et dénuée de déformations mécaniques. De plus, la différence qui existe entre les taux de gravure des matériaux induit un contraste de nature topographique entre les phases. La topographie est ensuite mesurée à l'aide d’un microscope à force atomique et les images obtenues permettent d’analyser avec précision la géométrie autour de la ligne triphasée. 2, record 1, French, - faisceau%20d%26rsquo%3Bions%20focalis%C3%A9

Because a magnetic field exerts a force on a charged particle, this solar field wave "breaks" over the comet, pulling on the ionized gas of the coma. It sweeps away the electrons, which are much lighter, and draws the heavier ions outward, into a long plasma tail (also called an ion tail) that points in the anti-sunward direction. 3, record 3, English, - anti%2Dsunward%20direction

C'est à l'approche du Soleil que les glaces se subliment dans le vide, entraînant les poussières du noyau. La comète devient alors visible. Tandis que la vapeur très légère reste confinée dans la coma, les poussières sont entraînées par la pression de radiation solaire dans la direction opposée au Soleil, formant une queue caractéristique. [...] La forme de la queue ionique s’explique par la formation d’une onde de choc. À l'intérieur de ce front l'écoulement du vent solaire est freiné par l'atmosphère de la comète et produit des turbulences qui prennent l'aspect de cordes, de nœuds et de filaments qui différencient la queue ionique de la queue de poussières. En dehors du front les ions associés à la comète sont entraînés par l'écoulement général, guidés par les lignes de force engendrées par le noyau en mouvement. Les ions s’échappent ainsi de la coma pratiquement dans la direction anti-solaire en formant une longue queue distincte. 5, record 3, French, - direction%20anti%2Dsolaire

Information on changes of enzymatic properties caused by the immobilization of enzymes and microbial cells is useful not only for the application of immobilized systems but also for the elucidation of structure-function relationships and mechanisms of enzyme reaction. The changes of enzymatic properties are considered to be caused by the following two factors. One is changes of the enzyme itself, and the other is physical and chemical properties of the carriers used for immobilization. The former involves modification of amino acid residues in the active center of the enzyme, conformational changes of the enzyme protein, and changes in the charge on the enzyme, while the latter involves the formation of diffusion layers around immobilized enzymes, steric hindrance effects, and electrostatic interactions between carrier and substrate. 3, record 18, English, - electrostatic%20interaction

At low concentrations (when only long-range coulombic forces need to be considered) the effect on a given reaction is determined only by the ionic strength of the solution and not by the chemical identity of the ions. For practical purposes, this concentration range is roughly the same as the region of validity of the Debye-Huckel limiting law for activity coefficients. At higher concentrations, the effect of an added electrolyte depends also on the chemical identity of the ions.

The physicochemical basis of salting-out is rather complex; one factor is that the high concentration of salt may remove water of hydration from the protein molecules, thus reducing their solubility, but other factors are also involved. Whatever their physical basis, salting-in and salting-out are important procedures in the separation of protein mixtures, since different proteins vary in their response to the concentration of neutral salts. Proteins precipitated by salting-out retain their native conformation and can be dissolved again, usually without denaturation.

Le relarguage(...) des protéines à force ionique élevée varie suivant les protéines. Il est donc possible, par un accroissement progressif de la concentration saline(sulfate d’ammonium ou de sodium), d’obtenir une précipitation fractionnée des diverses protéines. En fait, par ce procédé, on obtient presque toujours des mélanges de protéines. 3, record 26, French, - relarguage

The physical adsorption method for the immobilization of enzyme is based on the physical adsorption of enzyme protein on the surface of water-insoluble carriers. This method often causes little or no conformational change of the enzyme protein, or destruction of its active center. Accordingly, if a suitable carrier for the target enzyme is found, this method may be both simple and effective. However, this method has the disadvantage that the adsorbed enzyme may leak from the carrier during utilization, because the binding force between the enzyme protein and carrier is weak. 1, record 27, English, - adsorbed%20enzyme

L'immobilisation par adsorption met en jeu un grand nombre de forces d’interactions de faible énergie entre le support solide et la protéine : interactions de Van der WAALS, liaisons hydrogène ou liaisons hydrophobes.(...)
