We have synthesized the bulk form of the superparamagnetic nanocomposites of Fe nanoparticles and activated carbon. Here highly porous feature of activated carbon and magnetic properties of Fe nanoparticles were combined together to form the nanocomposites by mechanical mixing of different proportion of both of them.…
After chronic levodopa use, many patients with Parkinson disease (PD) develop involuntary movements. Whether disabling or minor, levodopa-induced dyskinesia (LID) constitutes an undesirable outcome calling for better treatment strategies. Options for managing LID include delaying its onset by combining a dopaminergic…
It is shown that an extra magnetization is induced by an onset of the equal-spin-pairing of spin triplet superconductivity if the energy dependence of the density of states of quasiparticles exists in the normal state. It turns out that the effect is observable in Sr_2RuO_4 due to the existence of van Hove singularity…
Tough elastomers are created by adapting an approach previously used for hydrogels. [Also see Report by Ducrot et al. ]
The Fourier modal method (FMM) has advanced greatly by using adaptive coordinates and adaptive spatial resolution. The convergence characteristics were shown to be improved significantly, a construction principle for suitable meshes was demonstrated and a guideline for the optimal choice of the coordinate transformati…
We report preliminary natural circular dichroism (NCD) spectra of amino acids, Land D-histidine, thin films in the nitrogen K -edge energy region. NCD peaks were observed at 399.9 eV and were assigned to the 1 s → π* transition of the nitrogen atoms in imidazole ring. Imidazole ring is positioned at the side chain dis…
We present a high-performance electron gun to be employed in crossed-beams electron-ion collision experiments. High electron currents, e.g., 1 A at 3.5 keV, have already been demonstrated verifying the results of electron optics simulations carried out prior to the mechanical construction of the gun. Currently, the de…
Over the past 20 years, the atomic force microscopy (AFM) has been playing a pivotal role in new discoveries and understanding in biological ields through its capability to image surfaces with nanometer-scale spatial resolution in liquid environments. In this chapter, we describe the basic operation of AFM, interpreta…

The sources and dynamics of arsenic in fresh volcanic ashes collected during the eruptions of Hudson (1991) and Puyehue (2011) volcanos, have been studied. The chemical and mineralogical compositions of both volcanic ashes were analyzed by ICP/OES, XRD, and SEM-EDS. Batch experiments were conducted to evaluate the kin…
A novel electricity-free deposition of palladium on the surface of manganese dioxide, which has a crystal structure of ramsdellite, was studied. Using the Pd deposition, a nano-particle of Pd/MnO2 was prepared, and it was used for a catalytic performance for reforming methane into hydrogen at 300°C.
정수 슬러지를 재활용하여 제조한 펠렛형 흡착제의 트리메틸아민과 암모니아의 흡착 특성을 연구하였다. 펠렛형 흡착제를 $110^{\circ}C$ 에서 건조 처리 했을 때보다 $500^{\circ}C$ 에서 소성했을 때 BET 표면적과 기공 부피가 증가하는 것을 알 수 있었다. 정수 슬러지를 재활용하여 제조한 펠렛형 흡착제는 브뢴스테드 산점과 루이스 산점을 보유하는 것을 확인하였다. 흡착질 가스인 트리메틸아민과 암모니아가 일정한 농도로 흡착제 층으로 유입되고, 흡착제의 중량과 흡착질의 선속도를 변화시키면서 흡착질 가스의 파과시간을 측정하였다. Wheeler의 흡착속도식을…
A new method for the preparation of sulfur (S) doped iron (Fe) samples is presented. The required amount of S in Fe is obtained by allowing the vaporized form of S to diffuse into a Fe sample (10 mm diameter, 0.5 mm thick) kept at a temperature of 750 K. Depth profile analysis using Auger Electron Spectroscopy and Tim…
Statistical and electrical properties of the conduction electrons of a silver or gold sphere with a radius from 1 to 2 nm are shown to differ drastically from the properties of electrons in a bulk metal sample. If the radius of a noble metal sphere decreases from 10 to 1 nm, its conductivity oscillates around the bulk…
Superstructure transformation processes in intermetallics have beenstudied at the atomistic scale using Monte Carlo algorithms within two dis-tinct models: two-body interactions Ising-like system and Analytic Bond-Order Potentials. The transformation from “in-plane” to “off-plane” L10 vari-ant in [001]-oriented FePt n…
