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…
Telah dilakukan pengamatan terhadap grid pattern (GP) pada sampel kristal cair nematik 4-methoxybenziledene-4-n-buthyl-aniline (MBBA) penjajaran planar dengan ketebalan 50μm dan 100μm. Pemberian medan listrik eksternal pada kristal cair nematik menyebabkan arah orientasi director molekul kristal cair berubah. GP muncu…
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…

We will report on a systematic study, aimed at understanding the dynamics of colloidal hard spheres inside microfluidic channels. Real-time confocal microscopy is used to visualize the structure, diffusion and flow of model suspensions of 1 micron diameter silica spheres. By controlling the flow speed, we cover a rang…
To date, the main method of mass production of advanced functional materials for various purposes is the ceramic technology. In the manufacture of multi-component oxide compounds using of ceramic technology is difficult to achieve high uniformity of chemical composition. For activation of the raw ingredients and make…
As fibras naturais estão atraindo interesse nos setores de engenharia, devido às vantagens específicas, tais como baixa densidade e custo, assim como a vantagem de ser renovável, biodegradável neutra em relação à emissão de CO2 e poder ser reciclada.. Em particular, a fibra extraída do caule da planta de rami é reconh…
The interaction of a solitary wave front with an interface formed by two strongly-nonlinear non-cohesive granular lattices displays rich behaviour, characterized by the breakdown of continuum equations of motion in the vicinity of the interface. By treating the solitary wave as a quasiparticle with an effective mass,…
Abstract This article presents a wide band compact high isolation photoconductive switch, which is based on the series‐shunt switch design with three photoconductive switches made of diced high‐resistivity silicon wafer placed over a microstrip gap and activated by 808‐nm near‐infrared laser diodes. The switch shows a…
The purpose of the present paper is to obtain some subordination-and superordination-preserving properties for multivalent function associated the differintegral operators defined on the space of normalized analytic functions in the open unit disk. The sandwich type theorem for the integral operator is also considered.
Abstract This article describes the design of on‐chip bandpass filter (BPF) with split ring resonators (SRRs) for millimeter wave application. SRR is one of the metamaterial structures commonly used in designing the passive component and is used to improve the performance of the device. In this design, the BPF is desi…
