Abstract Two novel two‐dimensional (2D) lanthanide(III) coordination polymers [Ln(PDC)(OH)(H2O)2]n (Ln=Eu (1) and Tb (2), H2PDC=pyridine‐3,4‐dicarboxylic acid) have been synthesized under hydrothermal conditions, and characterized by elemental analysis, IR, TGA and single‐crystal X‐ray diffraction. Both compounds show…
Network on Chip is emerging as a solution to the existing interconnection architecture constraints. Performance parameters like latency, throughput are critical issues in interconnection network design. Routing algorithms have a prominent impact on communication and performance in on chip interconnection networks. Thi…
Thin NiTi shape memory wires with unique thermomechanical properties are considered to be promising material for a wide range of new engineering applications. Based on broad experimental research on behavior of NiTi wires, which reveal a significant anisotropy in the transformation behaviors between tension and torsio…
Scanning probe microscopy (SPM) provides a range of strategies for studying biological phenomena due to its ability to image surfaces under liquids. However, some cellular events, such as cell migration, exceed the maximum measurable range of SPM. Recently, we have developed a wide range scanning probe microscope (WR-…
Control of the microstructures of (1–x)(Bi1/2K1/2)TiO3-xBaTiO3 (x = 0.1) [abbreviated as BKT–BT10] ceramics prepared by a reactive templated grain growth (RTGG) using platelike Bi4Ti3O12 particles as a template were investigated. All samples showed a single-phase perovskite structure. The degree of orientation F, whic…
The development of new production technologies for NiTi Shape Memory Alloys (SMAs) is always challenging. Recently, we introduced two powder metallurgical (PM) processing routes involving mechanical activation of elemental powder mixtures and densification through extrusion or forging. Those processes were named Mecha…
液晶ディスプレイの大型化に伴い，さまざまな光学的不均一さ“ムラ”が目立ちやすくなってきた。この原因には，材料の不均質さや生産プロセスでの処理条件の変動によるもの，また環境温度や湿度変化によって発生する歪みが考えられる。本研究では，環境変化においても光学特性に変化が生じないような材料設計が重要になることから，光学フィルム内部の水分拡散と膨潤応力解析技術を開発した。はじめに液晶ディスプレイで使用されている光学フィルム単体の吸湿関連の材料物性値を評価した。この材料物性値を用いて，光学フィルム単体の解析精度を検証したところ，吸湿歪みの計算値と測定値は定量的に非常に良い一致を見た。次に偏光板においては，計測された吸湿歪みと計算値には定量的に…
In this work we present preliminary results demonstrating the influence of electrical double layer overlap on the electromigration of polystyrene beads (PSB) through an array of 25 cylindrical nanopores. Each of the cylindrical nanopores of the array used in this study is 360nm long with a diameter of 90nm. We observe…
The conventional rolled‐up model for nanotubes does not apply to very small radii tubes, for which curvature effects become significant. An existing geometric model for carbon nanotubes proposed by the authors, which accommodates this deficiency and which is based on the exact polyhedral cylindrical structure, is exte…

The Cutia-nut (Couepia edulis Prance), a species originally from the Amazon region, has a kernel with reasonable nutritional value and a hard and thick woody shell that constitute most of the fruit. After the kernel removal, the shells are regarded as waste. The possibility of using such shells, as raw material for bu…
Solid oxide fuel cells (SOFCs) have been attracting attention as new power generating systems because of their advantageous features such as high conversion efficiency for co-generation and hybrid generation systems, multi-fuel capability, and absence of precious metal components.High temperature operation of the syst…
Estudam-se as ligas monocristalinas Cu-13,5Al-4Ni e Cu-13,7Al-4,2Ni que exibem transformações martensíticas reversíveis (TMR).As ligas foram submetidas a ciclos de aquecimento e resfriamento num intervalo que inclui as temperaturas críticas de TMR.Maior atenção é dada às alterações na estrutura das ligas com a ciclage…
Both the scientific experience and the engineering practice indicate that the decision making processes in the course of solving complex designing problems require an analysis of a great number of different construction variants. These types of decision-making processes are time consuming and do not always result in t…
A compressive torsion process, which is one of severe deformation processes, is applied to AZ61 magnesium alloy to control microstructure. This process is composed of relatively low compressive pressure and axial rotation, and can apply huge strain to a work piece without changing in shape during processing. Effect of…
The configurational entropy, diffusion coefficient, dynamics and thermodynamics fragility indices of liquid argon are calculated using molecular dynamics simulations at two densities. The relationship between dynamics and thermodynamics properties is studied. The diffusion coefficient depends linearly on configuration…

The hydroalkylation reaction of benzene and ethylbenzene over BEA zeolites with a Si/Al ratio of 9–190, MOR with Si/Al = 48, and MFI with Si/Al = 25 containing ruthenium, rhodium, platinum, or palladium was studied, as well as over the Ru/BEA zeolites with Si/Al = 42 doped with a second metal: nickel, cobalt, or rhodi…
In the framework of PSI’s FAST code system, the TRACE thermal-hydraulics code is being extended for representation of sodium two-phase flow. As the currently available version (v.5) is limited to the simulation of only single-phase sodium flow, its applicability range is not enough to study the behavior of a Sodium-co…
