Based on in situ observations with scanning electron microscopy (SEM), we investigated the low cycle fatigue (LCF) propagation behaviors of a Ta-rich single crystal nickel-based superalloy at 550oC in vacuum. Specimens in three different orientations, i.e. [010], [011] and [111], were tested in stress-controlled tensi…
Abstract The objective of this work was to demonstrate the utilisation of cornstarch–mimosa tannin‐based resins designed for application as an adhesive in particleboard production. Bond qualities of cornstarch–mimosa tannin–urea formaldehyde (UF) resins and commercial UF resin were assessed by using an automatic bondi…
In this study the effect of shot peening on the fatigue lifetime of a near pearlitic microalloyed steel was investigated. The fatigue tests were run in strain control with parallel recording of stress relaxation and recovery of the work hardened surface zone at different total strain amplitudes exerted to the test spe…
The effect of deformation induced martensite on the HCF and VHCF properties of austenitic stainless steel sheets in different conditions was studied. In the undeformed condition true VHCF fatigue limit exists even though microplasticity (slip markings) could already be found at a stress amplitude of less than a third…
Abstract Banana and maize starches were acetylated with acetic anhydride in the presence of different levels of catalytic agent (iodine) using microwave heating. Degree substitution, he Fourier transforms infrared (FT‐IR) spectra, the morphological properties, the gelatinization and retrogradation characteristics, the…
Terra Nova, 22, 264–273, 2010 The problem of location of the North China Block (NCB) during the Palaeozoic and its history of uplift and erosion have not been established satisfactorily. A regional unconformity was developed in the NCB between the Upper Ordovician and the Middle–Upper Carboniferous. Zircon grains in t…
Single-phase samples of Ba 4 R 3 F 17 · n H 2 O (R = La, Ce, Pr, Nd, Eu, Gd, Y, Er, or Yb; n = 2.5−3.2) were prepared by coprecipitation from nitrate solutions using hydrofluoric acid. The phases crystallize in a fluorite-type face-centered cubic lattice. The dried precipitates are transparent. Scanning electron and a…
This paper describes the current status of the design study and the related research and development for an advanced loop-type fast reactor: the Japan sodium-cooled fast reactor (JSFR). First, the development targets and the major design requirements are established. Then, a cost-down approach in which developing inno…

A systematic study was conducted to understand the size and shape of nanopatterns generated on selected semiconducting (Si and Ge) and metallic (Cr, Cu, and Ag) targets under different laser pulse durations, laser energies, and number of laser pulses. Based on the experimental results, femtosecond laser pulses, compar…
The effects of organic additive, 3-S isothiuronium propyl sulfonate (UPS) on bath stability, deposition rate, reaction activation energy, and Ni-P coating composition in acidic electroless nickel (EN) plating were investigated. The study was performed by measuring the polarization curves and X-ray fluorescence spectro…

Aluminum oxynitrides Al 22 O 30 N 2 and Al 23 O 27 N 5 and a number of Al-O-N solid solutions with a nitrogen content of 2.3 to 6.5 wt % were prepared from (CrO 3 -Al-Al 2 O 3 -AlN) thermite-type mixtures with a high combustion temperature (2950–3200 K) by using the autowave synthesis method. The synthesis was conduct…
A model for the synthesis of a substrate-based coating under heating by a moving energy source typical for electron-beam treatment has been suggested and analyzed. It has been taken into account that the condensed-phase chemical conversions are accompanied by volume changes and mechanical stresses and deformations in…
In general, the prediction of pipeline residual life can effectively assist pipeline operators to evaluate future safe operating strategies including re-inspection and appropriate maintenance schedule. As a result it can minimize the possibility of pipeline failures until it reaches its designed lifetime. A semi-proba…
A new 3-D copper(II) complex, formulated as [Cu2(btec)(en)2] n (1) [H4btec = benzene-1,2,4,5-tetracarboxylate, and en = ethylenediamine], was hydrothermally synthesized and structurally characterized by elemental analysis, IR spectroscopy, thermal gravimetric analysis, and single crystal X-ray diffraction. The structu…
A pulsed-cap microcolumn was used for bromelain extraction from pineapple juice by reversed micelles. The cationic micellar solution used BDBAC as the surfactant, isooctane as the solvent and hexanol as the co-solvent. In order to capture the dynamic behavior and the nonlinearities of the column, the operating conditi…
Protein domains usually fold without or with only transiently populated intermediates, possibly to avoid misfolding, which could result in amyloidogenic disease. Whether observed intermediates are productive and obligatory species on the folding reaction pathway or dispensable by-products is a matter of debate. Here,…
Os teores e as características da matéria orgânica do solo (MOS) são resultados das taxas de produção e incorporação, decomposição ou alteração e mineralização, de acordo com as condições do ambiente. Nos solos hidromórficos, a dinâmica da MOS é influenciada pelo déficit de oxigênio, o que diminui a taxa de decomposiç…
Abstract A series of substituted 3‐benzothiazolylcoumarins was prepared from condensation of 2‐hydroxy‐benzaldehyde and 2‐cyanomethylbenzothiazole to investigate the effect of the nature and position of substituents on their absorption and fluorescent behavior. Compounds with a substituent containing a heteroatom whic…
