Since n-hexane is a non-polar molecule, Ens>>Esp' and therefore the value of E0 is dependent on the overall dispersion forces and hence on the density of the force centres in the outer part of the adsorbent (i.e. its surface structure). Dehydroxylation of a silica surface involves very little change in surface structure and therefore no significant difference in the value of E0 for n-hexane. However, replacement of the surface hydroxyls by alkylsilyl groups has resulted in much greater effect. In this case the weakening of the adsorbent-adsorbate interactions is mainly due to the fact that the surface modification has resulted in a reduction in the density of the force centres. The polarizabilities of benzene and hexane are very similar, but because of its electronic structure benzene exhibits significant specificity in its interaction with ionic or polar surface (e.g. hydroxylated silica and barium sulphate). Considerable attention has been given to the specificity associated with hydroxylated silica, but some specific adsorbent-adsorbate interactions are enhanced to an even greater to an even greater extent by the exposure at the surface of ionic sites. This is illustrated by benzene data on BaSO4 in Table 1.4 and the nitrogen data on rutile in Table 1.5.

テーブル１．４の種々の非ポーラスな固体上のノルマルヘキサンとベンゼンの吸着に対する”Low coverage”エネルギーデータは吸着剤の表面構造と吸着の性質の重要性を示す。ノルマルヘキサンは非極性分子なので、Ens＞＞Esp'であり、それゆえE0値は全体の分散力と吸着剤の外周部での力中心（？force centres）の密度に依存する。（例えば、その表面構造）シリカ表面の脱水酸基反応は非常に小さな表面構造の変化を含み、ノルマルヘキサンのE0値に大きな違いを与えない。しかしながら、アルキシリル基による表面水酸基の置換は更に大きな効果を生んだ。吸着剤と吸着物の相互作用が弱まるのは、表面改質が力中心の密度の減少の結果であることによる。 ベンゼンとヘキサンの分極能は非常に近いが、その電子的構造からベンゼンはイオン性、または極性表面との相互作用に大きな特異性を示す。（例えば、水酸基修飾されたシリカや硫酸バリウム）水酸基修飾されたシリカに特別の注目をしたが、いくつかの特異的な吸着剤と吸着物の相互作用はイオン性の部分の表面に露出することによってより拡張され増大が得られた。これはテーブル１．４の硫酸バリウム上のベンゼンのデータとテーブル１．５のルチル上の窒素のデータによって示される。 日本語がよれていますが参考になれば・・・この部分はリニアなalkaneとベンゼンは極性面では同じようなものだけれど、ベンゼン環の電子分布が示す極性により異なった挙動を示すことと吸着剤の表面構造の変化が吸着能に大きな変化をもたらすみたいな内容じゃないでしょうか？

However, the energy data in Table 1.5 show that this is true only if the nitrogen interaction is non-specific (e.g. on graphitized carbon). The filed gradient-quadrupole term in Equation (1.6) makes an important contribution when nitrogen is adsorbed on such polar or ionic surfaces as hydroxylated silica, rutile and zinc oxide. In the case of rutile, cationic sites are exposed when the adsorbent is outgassed at 400 and these interact very strongly with nitrogen at low surface coverage. The results in Table 1.5 also reveal that with some systems the differential enthalpy undergoes a pronounced change with increase in surface coverage, whereas in other cases the change is much smaller (at least up to S=0.5). An increase in the enthalpy of adsorption (e.g. with argon on graphitized carbon) is likely to be due to the attractive interactions between adsorbed molecules ('lateral interactions') becoming more important as the population in the monolayer is increased or as micropore filling approaches completion. The more usual progressive decrease in the differential enthalpy is generally to be expected if the adsorbent surface is energetically heterogeneous. However, it is necessary to bear in mind that there may be compensatory effects involved. Thus, the computer simulation studies of Steele and Bojan (1989) have indicated that for the adsorption of krypton on a model heterogeneous surface an almost constant overall energy is the result of a significant decrease in the adsorbent-adsorbate interactions begin almost exactly balanced by an increase in the lateral adsorbate-adsorbate interactions.

In practice, only a limited number of atoms are taken into account because of the rapid decrease in energy with distance. The balance between attractive and repulsive interactions means that a point exists, at distance ze from the surface, where the potential energy of the molecule is minimum, as represented in Figure 1.2. Of course, the value of Li(z) must depend not only on the distance from the surface but also on the location on the surface (i.e. in the xy plane). If this is in the form of one face of a perfect crystal, there will be a regular variation of potential energy across the surface. It is not surprising to find that the most favorable site is at the centre of an array of surface atoms (cf. Figure 1.3). The corresponding depth of the potential energy well (at ze) will depend on the density and crystal structure of the absorbent and the polarizability and molecular size of the adsorbate. The easiest path for the movement of the adsorbed molecule across the surface is via a col or 'saddle point' and the energy barrier to translational movement in the xy plane is given by the difference in the corresponding minima potential energies for the two locations (Figure 1.3).

Mobility of Adsorbed Molecules The translational movement of adsorbed molecules is governed by the amplitude of the oscillations of Li(z) across the surface and by the available thermal energy. If the variations in Li(z) are much smaller than the mean thermal, kT, the energy barriers between adsorption sites are small enough to be overcome easily at the operational temperature: the adsorbed molecules therefore retain two translational degrees of freedom and can be regarded as mobile. On the other hand, if the energy barriers are much larger than kT, the adsorbed molecules are said to be localized since they spend most of their time on particular surface sites. In the hypothetical case of a perfectly homogeneous surface, there is no variation of Li(z) in the xy plane - see Figure 1.4a. It is more realistic to picture a uniform surface, which gives rise to energy wells of the same depth. Now, the potential energy profiles corresponding to mobile and localized adsorption are shown respectively in Figures 1.4b and 1.4c. In the former case, there is a random distribution of adsorbed molecules across the surface; whereas in the latter case, the location of the adsorbed molecules is governed by the surface structure of the adsorbent. Localization does not prevent the adsorbed molecules from 'hopping' from one site to another (unlike the situation in immobile chemisorption), but it is not compatible with the state of a close-packed completed monolayer.

But the four selected - du Pont, General Motors, Jersey Standard, and Sears - were among the very first to initiate major reorganizations of this kind. What is important for this study is that the executives of these four began to develop their new structure independently of each other and of any other firm. There was no imitation. Each thought its problems were unique and its solutions genutine innovations, as brand new ways of administering great industrial enterprises. In time, the innovations became models for similar changes in many American corporations.

When a polar molecule is adsorbed on an ionic or polar surface various types of specific interactions may contribute to the adsorption energy. A useful general expression for the adsorption energy, E0, at very low surface coverage was first proposed by Barrer (1966) in the form of the sum (1.6) in which ED and ER represent the non-specific dispersion and repulsion contributions and the terms EP, EFμ and EFQ represent, respectively, the three types of specific contributions: the polarization, field-dipole and field gradient-quadrupole energies. For convenience, we may write Equation (1.6) in the form with Ens now is place of (ED+ER) representing the non-specific contributions and Esp representing the various specific contributions. If we wish to study the adsorbent-adsorbate interactions we must undertake adsorption calorimetry or analysis of the isotherm data at very low surface coverage. It is only under these conditions that we can eliminate, or at least minimize, the adsorbate-adsorbate interactions. At higher coverage, an additional (self-potential) term, Eaa, must be added to E0 to allow for the latter interactions.

Here E0 is measured from the enthalpy of adsorption, [Padsh’0] (determined by the chromatographic method at very low surface coverage, as explained in Chapter 3). E0 is plotted against the number of carbon atoms, NC, in the various series of hydrocarbons. It is striking that there is an almost common linear relation between E0 and NC. Thus, for a given NC, quite close agreement is obtained between the corresponding values of E0 for the series of alkanes, alkenes and aromatic hydrocarbons (Cao et al., 1991). By plotting experimental and theoretical low-coverage enthalpies of adsorption as a function of the molecular polarizability, Avgul and Kiselev (1970) also obtained a linear relation for wide range of polar and non-polar molecules on graphitized carbon black (including noble gases, dimethyl ketone, ethyl ether and a series of alcohols). We may conclude that there is ample evidence to confirm the essentially non-specific nature of the interactions between the surface of graphitized carbon and all types of gas molecules.

The textural relationships between these grains suggest progressive transformation of primary amorphous patches to more-ordered silica phases that have grown at the expense of the amorphous hydrous silica (Fig. 3). Two features record the presence of colloidal silica particles within the layer when it formed (Fig. 3).

    1.4 DNA structure and function DNA is huge ladder-like molecule made up of sugar , phosphate and four organic bases called Adenine, Guanine, Cytosine and Thymine.The bases will only join up in the pairs A to T and G to C. The two halves of the ladder can also un-zip between the pairs of bases.They do this: (a) At mitosis: each half ladder forms the other half on itself.So two ladders,which are identical, result.This is the reason why a chromosome that splits in mitosis forms two identical chromosomes. (b) When genes make proteins: each half ladder forms a related substance, RNA(very similar to DNA) on it.This then detaches, passing to the ribosomes.RNA carries the sequence of bases that were in the DNA.Each three letter ‘word’(triplet),e.g.AGC attracts particular amino acid to the ribosome. The sequence of the hundreds of triplets is what determines the kind of protein formed at the ribosomes-each protein has its own unique DNA sequence. Thus a length of DNA with its own unique sequence is a gene; and a gene is what is used to make its own, unique,protein by linking a particular sequence of amino acids together at ribosome. The‘ladder’structure of DNA is in fact turned into a spiral(double helix) thread,with 10 base pairs per complete 360°turn.This has little to do with the function of DNA but it was a crucial fact, discovered by Franklin, Wilkins, Watson and Crick, in determining its structure. かなり長いですがお願いします。 すごく急いでます。

    The aim of the physician in the treatment of insanity is to bring the means at his command to bears, directly or indirectly,on the disordered nerve element.But,in striving to do this,he soon learns with how many bodily organs and fuctions he has really to do. To call mind a function of the brain may lead to much misapprehention,if it be thereby supposed that the brain is the only organ which is concerned in the function of mind.There is not an organ in the body which is not in intimate relation with the brain by means of its paths of nervous communication,which has not ,so to speak,a special correspondence with it through internuncial fibres,and which does not,therefore affect more or less plainly and specially its[its=the brain's]function as an organ of mind.It is not merely that apalpitating heart may cause anxiety and apprehension,or a disordered liver[may cause]gloomy feelings,but there are reasons to believe that each organ has its specific influence on the constitution and function of mind:an influence not yet to be set forth scientifically,because it is exerted on that unconscious mental life which is the basis of all that we consciously feel and think. Were the heart of one man to be placed in the body of another it would probably make no difference in the circulation of the blood,but it make a real difference in the temper of his mind.So close is the physiological sympathy of parts in the commonwealth of the body that it is necessary in the physiological study of mind to regard it as a function of the whole organism,as comprehending the whole bodily life.
