DEER (double electron-electron resonance) is a powerful pulsed ESR (electron spin resonance) technique allowing the determination of distance histograms between pairs of nitroxide spin-labels linked to a protein in a native-like solution environment. However, exploiting the huge amount of information provided by ESR/D…
We report synthesis, characterization, and properties of a multifunctional oxalate framework, {KDy(C 2 O 4 ) 2 (H 2 O) 4 } n ( 1 ) (C 2 O 4 2– = oxalate dianion) composed of two absolutely different metal ions in terms of their size, charge, and electronic configuration. Dehydrated framework ( 1′ ) exhibits permanent…
Nanosized graphene quantum dots were prepared by acid etching of carbon fibers and used as effective substrate supports for platinum nanoparticles which were synthesized by thermolytic reduction of platinum(II) chloride in ethylene glycol. Transmission electron microscopic measurements showed that the resulting nanoco…
Adsorption and release of the biologically active nitric oxide (NO) was evaluated over a series of highly flexible iron(III) dicarboxylate MOFs of the MIL-88 structure type, bearing fumaric or terephthalic spacer functionalized or not by polar groups (NO 2, 2OH). As evidenced by ex situ X-ray powder diffraction and in…
The low temperature transport and magnetic properties were investigated in the misfit-layered Ca 2 Co 2 O 5 compound. The compound exhibits incommensurate spin-density-wave (SDW) state in the dχ -1 /dT curve at 20 K, which is confirmed by the resistivity (ρ) characterization. The resistivity shows an upturn from metal…
This work was focused on the production and characterization of lightweight and water resistance particle boards with various lignocellulosic materials of the annual plants hemp (Cannabis sativa L.), canola (Brassica napus L.) and bagasse (Saccharum officinarum L.) in admixtures with industrial wood. Some chemical pro…

This paper presents the results of a numerical simulation of the ultimate flax fibre ( Linum usitatissimum) tensile mechanical behaviour using finite element analysis. Experimental data were used to develop a numerical multilayer model of the flax fibre. Thus, the influence of some parameters, such as cell wall thickn…
The efficiency of chemical biocides as anti-bacterial agents is well documented and there are various methods to incorporate these bactericidal agents onto commonly used substrates, such as textile materials. Silver is known for its excellent inhibitory properties due to its direct action on the morphology of the cell…
We provide a unified spectroscopic evidence of efficient energy transfer (ET) from optically excited colloidal nanocrystal quantum dots (NQDs) into Si substrates in a broad range of wavelengths: from visible (545 nm) to near-infrared (800 nm). Chemical grafting of nanocrystals on hydrogenated Si surfaces is achieved v…
A methodology leading to facile self-assembly of crystalline aromatic arrays in dilute aqueous solutions would enable efficient fabrication and processing of organic photonic and electronic materials in water. In particular, soluble 2D crystalline nanosheets may mimic the properties of photoactive thin films and self-…
Electromigration (EM) is one of the key concerns going forward for interconnect reliability in integrated circuit (IC) design. Although analog designers have been aware of the EM problem for some time, digital circuits are also being affected now. This talk addresses basic design issues and their effects on electromig…
Development of reliable and ecofriendly green approach for synthesis of metallic nanoparticles biologically is an important step in the field of application of nanoscience and nanotechnology. The present paper reports the green approach for iron nanoparticle synthesis using Aspergillus oryzae TFR9 using FeCl 3 as a pr…
Recently a paper by Lin and Ku \cite{lin} was posted, where the authors propose a very interesting idea to engineer the Dirac points in material which originally did not have such points by inducing a CDW state through introduction of impurities like vacancy, substitution, or intercalation. In this comment we would li…
Nanotechnology is a science of producing and utilizing nanosized particles that are measured in nanometers. The unique size-dependent properties make the nanoparticles superior and indispensable as they show unusual physical, chemical, and properties such as conductivity, heat transfer, melting temperature, optical pr…

The desorption behaviors of Cs from Cs bearing smectite by major cations (Na^+, K^+, Mg^<2+>, Ca^<2+> and NH_4^+) were systematically examined. The suspension of the Cs bearing smectite was prepared by reaction of 1g/L smectite with 75 nM Cs^+ solution in 0.02 M NaCl solutions. The desorption behaviors of Cs were exam…
【緒言】当研究室では生体用磁気共鳴イメージング（MRI）の研究を各種展開している１。今回の研究の目的はMRIに適用可能な新しいナノ粒子を創製することである。MRI造影剤のマンガン化合物の水溶性を利用したナノ粒子（w/o/w型ナノカプセル）を設計、調製法を検討した。このナノカプセルは、粒子最深部にマンガン化合物水溶液、中間層にPLGA、および表面にPEG脂質を有する。【実験】ナノカプセルは文献２の実験項を参考にして調製したダブルエマルジョン型である。各材料を機能毎に置き換え工程も大幅に省略し作成した（スキーム１参照）。２回のエマルジョンは超音波処理で生成させた。この２段階では、混合する両溶液の濃度、量比、処理温度時間を変化させた。ま…

A current focus in studies of the glass transition is the role of dynamic heterogeneities. Although these efforts may clarify the origin of the spectacular change in properties of liquids approaching vitrification, we point out that a seemingly related phenomenon, thermorheological complexity in polymers, must involve…
