Chemical and microstructural characterization of propanethiol plasma polymer films by XPS and ToF-SIMS
Plasma polymer films (PPF) are promising organics materials for tailoring surface functional properties presenting a high crosslinking degree which influences its mechanical and thermal properties. In particular, propanethiol plasma polymer films (SH-PPF) could be useful for applications such as supports for gold nano…
Electrospray deposition from fountain pen AFM probes
In this paper we present for the first time electrospraying from fountain pen probes. By using electrospray contactless deposition in an AFM setup becomes possible. Experiments on a dedicated setup were carried out as first step towards this goal. Spraying from 8 and 2 µm apertures was observed. For the 2 µm apertures…
Cavitation-Induced Fusion: Proof of Concept
Cavitation-induced fusion (also known as bubble fusion or sonofusion) has been a topic of much debate and controversy and is generally (albeit incorrectly) perceived as unworkable. In this paper we present the theoretical foundations of cavitation-induced fusion and summarize the experimental results of the research c…
The Audio Frequency Conductance Study of Some Metal Succinate Salts in Aqueous Medium at Different Temperatures (Part I: Magnesium, Manganese (II), Barium and Copper Succinates)
The audio electrical conductances of aqueous solutions of magnesium, manganese II, barium, and copper succinates have been measured at various temperatures in the range of 298.15 K to 313.15 K, using an audio frequency conductance bridge. The evaluation of conductance data was carried out by minimisation technique usi…

Coaxial Self-Trapping of White and Gray Regions of an Incandescent Field: A Bright Core with a Dark Cladding
We report the generation of a self-trapped incoherent hybrid beam comprising a dark-sheathed bright core. The hybrid beam originates from refractive index changes in a photocrosslinkable organosiloxane, which allow simultaneous and cooperative self-trapping of a gray ring with a white core embedded in a broad incandes…
Design and Characterization of Novel Biodegradable Polymer-Clay-HydroxyapatiteNanocomposites for drug delivery applications
In recent years, biodegradable polymer based nanocomposites have been used promisingly for various drug delivery systems and biomedical applications as compared to synthetic polymer composites because of the biocompatible and biodegradable behavior of natural polymers. These biodegradable polymer nanocomposites also s…

Optimization of the Synthesis of Nanostructured Tungsten-Molybdenum Bimetallic Oxide
nanoparticles were prepared through the Pechini process and were characterized using X-ray diffraction (XRD), transmission electron microscopy (TEM), FT-IR spectrometer, and differential thermal analysis (TG-DSC) analyses. The polyesterification reaction, as the starting step, has a profound influence on the dispersio…
Ultrasensitive On-Chip Immunoassays with a Nanoparticle-Assembled Photonic Crystal
Electrophoretic particle entrapment system (EPES) is employed to generate 2D array of nanoparticles coated with biological molecules (i.e., antibodies). Phase matching of the excitation and the emission in the 2D arrays with particles produces a highly enhanced fluorescence signal that was shown to improve the limit o…
Competition between Collapse and Breakup in Nanometer-Sized Thin Rings Using Molecular Dynamics and Continuum Modeling
We consider nanometer-sized fluid annuli (rings) deposited on a solid substrate and ask whether these rings break up into droplets due to the instability of Rayleigh-Plateau-type modified by the presence of the substrate, or collapse to a central drop due to the presence of azimuthal curvature. The analysis is carried…
Role of H+ in Polypyrrole and Poly(3,4-ethylenedioxythiophene) Formation Using FeCl3·6H2O in the Room Temperature Ionic Liquid, C4mpyrTFSI
The polymerisation reaction of pyrrole and 3,4-ethylenedioxythiophene using the chemical oxidant FeCl3·6H2O in the room temperature ionic liquid butyl-methylpyrrolidinium bis(trifluoromethanesulfonyl)imide (C4mpyrTFSI) has been investigated using cyclic voltammetry, UV/vis and IR spectroscopy. The voltammetric data fo…
Synthetic and Structural Exploration of [24]Tetrathiacalix[2]arene[2]pyrimidines
A novel class of two atom bridged metacyclophanes-[2(4)]thiacalix[2]arene[2]pyrimidines-has been synthesized via a straightforward S(N)Ar reaction. The conformational properties and intra-annular dimensions of the [2(4)]thiacalix[2]arene[2]pyrimidines were evaluated by X-ray structure analysis and compared with known…
Growth of In Situ Functionalized Luminescent Silver Nanoclusters by Direct Reduction and Size Focusing
We have used one phase growth reaction to prepare a series of silver nanoparticles (NPs) and luminescent nanoclusters (NCs) using sodium borohydride (NaBH(4)) reduction of silver nitrate in the presence of molecular scale ligands made of polyethylene glycol (PEG) appended with lipoic acid (LA) groups at one end and re…

In order to obtain the high surface durability of power transmission gears and to promote environmental protection, the tooth surface-finishing method using a plastic material was developed. In this paper, the influence of machining condition on tooth surface texture of case-carburized gears was studied. First, the va…
SPIO-containing unilamellar polyion complex vesicles (PICsome) for in vivo tumor detection using MRI
Introduction: Size-tunable unilamellar polyion complex vesicles (PICsome) has been developed as anovel nano-vesicle for therapeutics and diagnosis (Anraku Y, et al; J Am Chem Soc., 2010). Theaccumulation of Cy5-labeled PICsomes in tumor has recently been demonstrated using a fluorescenceimaging technique (Anraku Y, et…
定量的マンガン造影 ＭＲＩによる抗がん剤に対する主要細胞 viability の評価
【背景】Mn2+は、Ca2+チャネルを介した輸送を行う細胞内造影剤として知られ、マンガン増感MRI（MEMRI）として利用されている。非貪食性細胞にも取込まれ(Aoki et al., NMR in Biomed 2006)、放射線照射後の腫瘍細胞において、細胞周期停止に依存してMn2+の細胞内取り込みが減少する報告がある (Saito et al., Proc of ISMRM2011)。今回、抗がん剤で処理したがん細胞における細胞内Mn2+取り込みの変化をマンガン造影MRIにより検討した。 【方法】マウス大腸がん細胞Colon26に抗がん剤（ドキソルビシン）を含む培養液の下で48時間培養した後、フローサイトメトリーを計測した。…
ワークショップの企画にあたって
放射線適応応答は、予め低線量放射線を照射しておくことにより、その後の高い線量の放射線に対する感受性が一過性に低下する生体応答である。 感受性の低下は、一般的に低線量放射線照射後数時間から始まり、1 日程度で終息する。しかし、低線量率放射線照射が長時間に渡る場合には、放射線抵抗性が持続的に誘導される可能性も考えられることから、福島原子力発電所 事故にともなう住民の長期被ばくの健康影響評価においても考慮すべき生体応答と考えられる。本ワークショップでは、放射線適応応答の分子機構 に関する研究の現状をまとめ、今後の適応応答研究の進展の方向性を探ることを目的としている。
