Yosida

Yosida et al. [41] found that p-t< rr-butylcalix[6]ar-ene can extract Cu from the alkaline-ammonia solution to the organic solvent. Nagasaki and Shinkai [42] described the synthesis of carboxyl, derivatives of calix-[n]arenes ( = 4 and 6) and their selective extraction capacity of transition metal cations from aqueous phase to the organic phase. Gutsche and Nam [43] have synthesized various substituted calix[n]arenes and examined the complexes of the p-bromo benzene sulfonate of p-(2-aminoethyl)calix[4]arene with Ni, Cu , Co-, and Fe. ...

The canonical spin glass consists of a noble metal (Au, Ag, Cu, or Pt) diluted with a transition metal ion, such as Fe or Mn. The magnetic interaction in such systems is mediated by the conduction electrons, leading to an indirect exchange interaction—the RKKY (Ruderman and Kittel [70], Kasuya [71], and Yosida [72]) interaction, whose coupling constant J R) oscillates strongly with distance r between the spins as...

Here we have in mind such materials as EuS with a comparatively high concentration of Gd atoms to give a degenerate electron gas, and a large number of metallic transitional-metal compounds where ions of mixed valence exist (in the latter there may be uncertainty about whether the electrons are in a conduction (4s) band or the upper Hubbard band described in Chapter 4). In such a case a new interaction term arises between the moments which is via the conduction electrons. This is the so-called RKKY (Ruderman-Kittel-Kasuya-Yosida) interaction, which is an oscillating function of distance (Ruderman and Kittel 1954, Kasuya 1956, Yosida 1957 for a detailed description see Elliott 1965). This derives from the formulae of Chapter 1, Section 5. Consider an atom with magnetic moment in a given direction then the wave functions of conduction electrons with spin up and with spin down will vary with distance in different ways, so that...

In addition to variations in citrus extracts, there are features of bioflavonoid effects on the mammalian body which may have contributed greatly to the controversy concerning flavonoid action. In 1940 Yosida (13) and in 1955 Rinehart (14) reported effects of hesperidin on rheumatic fever. Yosida determined the erythrocyte sedimentation rate (ESR) before and after injecting hesperidin into patients. In 26 sets of determinations the ESR was retarded in 19, unchanged in 3 and accelerated in 4 cases. Rinehart administered hesperidin to 26 patients, 22 showed a decreased ESR, 1 an unchanged and 3 an increased ESR. Hence, by the usual interpretation that an increased ESR indicates pathology, hesperidin in some cases showed beneficial effects, in others no effect and in still others made the disease worse.
