    Notes:
    Monomolecular layers of exfoliated MoS2 are incorporated in the process of the formation of Co ferrite from aqueous solutions. The presence of MoS2 is found to limit the coalescence of particles during reduction to Fe(Co) metal. That MoS2 inhibits the full conversion to metal is confirmed by Mössbauer effect spectroscopy. Magnetization measurements are interpreted on the basis of noncollinear magnetization patterns resulting from competing surface anisotropies.

    Notes:
    The effect of various additives on hot workability was investigated for alloy systems of (Nd13.6−xRx)(Fe77.6−yTyCo2.8)B6.0: R=Ce, Dy; x=0, 1, 2; T=Al, Si, V, Cu, Ga, Zr, Nb, Mo, Sn; y=0, 0.5, 1.0. A semiquantitative comparison of the effect of various additives was made by measuring the crack opening displacement (CODmax) in test specimens deformed in an open (unconstrained) configuration. Among the additives, cerium and silicon improved the hot workability while niobium and tin severely deteriorated the workability. The remanence anisotropy ratio was inversely related to CODmax. Detailed microstructural investigations were carried out with alloys which had only cerium or tin to study the reason for their hot workability behavior in comparison to the base alloy. The improved hot workability of cerium added alloy is related to the lower melting temperature of the intergranular phase and faster grain growth compared to the base alloy. Tin addition prevented grain growth with no endothermic peak in a differential thermal analysis curve, indicating the absence of boundary phase melting, and leading to poor hot workability.

    Notes:
    Cobalt ferrite, CoxFe3−xO4 with 0.55≤x≤0.8, is produced by precipitation from aqueous solutions. Drying and annealing at temperatures below 300 °C results in a coercivity that increases with increasing temperature. Mössbauer effect spectroscopy and magnetic measurements are consistent with the interpretation that these Co ferrites have a (mostly) normal spinel structure as made. These convert to a (mostly) inverse spinel structure on thermal aging. No significant morphological changes occur during this transformation. Coercivities as high as μ0Hc=0.2 T are observed.

    Notes:
    Anisotropic Nd-Fe-B magnets are produced from melt-spun ribbons by hot working technique. The processing is facilitated by improved workability. In order to obtain a sound magnet, it is important to suppress the crack initiation and growth. An investigation was carried out to study the deformation mechanism of the alloy system and to improve workability by changes in alloy composition. Alloy ribbons with composition (Nd13.6−xRx) (Fe77.6−y Ty Co2.8)B6.0 [R=Ce, Dy; T=Al, Si, V, Cu, Ga, Zr, Nb, Mo, Sn; x= 0, 1, 2; y=0, 0.5, 1.0] were prepared by melt spinning and then hot pressed into fully dense compacts. These compacts were upset in a hot working simulator. Hot workability was evaluated by measuring the crack opening displacement on the surface at the half height of the upset specimen. The relationship between strain rate and flow stress was found to be expressed by the equation: ε(overdot) = Aσn exp( − Q/RT). Values of n and Q were obtained for quarternary composition (Nd-Fe-Co-B). The effects of strain and strain rate on magnetic properties were also studied for quarternary composition. Of the additive elements, cerium and silicon addition showed significant improvement in workability without loss of coercivity.

    Optical properties of conducting polymers with Si atoms in main chains, such as optical absorption, photoluminescence (PL), and electroluminescence (EL), have been studied. The electronic energy structures have been determined by optical and electrochemical measurements. The strong PL with high quantum efficiency has been clarified, and spectral narrowing has been observed by pulse excitation of a nitrogen laser. Intense blue or red EL has also been demonstrated and the emission efficiency has been improved by anode surface modification and annealing. © 2001 American Institute of Physics.

    Notes:
    A low-pressure and high-density microwave ion source created and sustained by evanescent waves emitted from a holey plate, and using permanent magnet multicusp fields, has been studied. This source is called a holey-plate ion source. Microwave power at 2.45 GHz is supplied from a coaxial cavity and then converted into an evanescent mode through the use of a holey plate. This source can produce low-pressure and high-density plasma using an octopole magnetic field. The ion current densities are in excess of 4.8 mA/cm2 at an extraction voltage of 3 kV, an argon gas pressure of 0.3 Pa in the plasma chamber, and an input microwave power of 80 W. An 18-mm-diam ion beam is extracted and accelerated from the ion source. © 2000 American Institute of Physics.

    Notes:
    A 66-year-old male, whose primary skin lesion in extramammary Paget's disease had been surgically resected 4 years previously, was hospitalized with liver metastases. Hepatic arterial infusion chemotherapy was carried out and the tumours clearly reduced in size. Serum levels of some common tumour markers were not elevated, even prior to therapy. We measured serum levels of a novel tumour-associated antigen, RCAS1, because its expression was detected in the tumour cells. The patient's serum RCAS1 level was elevated (22.0 U/mL) before therapy and fell during (10.5 U/mL) and after (5.0 U/mL) therapy. Therefore, serum RCAS1 levels may be valuable as a potential biomarker for monitoring therapeutic efficacy against Paget's disease.
