Nano-scale finite element approach was used to predict the mechanical properties of carbon nanotubes. The unit-cell isolation scheme was same as that from Eric Seather [1], and nothing was assumed to exist inside any nanotube. Arm-chair, zigzag and chiral type of nanotubes with different radii were discussed in detail…
A series of random poly(ester amide)s with different chemical compositions and derived from sebacoyl dichloride, 1,6-hexanediamine and 1,6-hexanediol was synthesized and characterized. In addition, a poly(ester amide) with equal ratio of 1,12-dodecanediamine and 1,12-dodecanediol units was prepared. All these poly(est…
The nor-clerodane diterpene trans-crotonin isolated from the bark of Croton cajucara BENTH. was investigated for its ability to prevent the formation of gastric-mucosa ulceration in different experimental models in mice. The results obtained from crotonin were compared with those obtained with another diterpene, DHC (…
The evaluation methods of the delayed fracture properties of high strength steels and the methods which improve the delayed fracture resistance of steels have been reviewed. The evaluation method which is crucial for the development of steels with high strength has yet to be authorized. However, a new evaluating metho…
We synthesised a series of linear bis(triarylamine) species whose triarylamine redox centres have different local redox potentials which were tuned by substituents in the para-position. The mixed-valence (MV) radical cations of these systems were generated and investigated in situ by UV/Vis/NIR spectroelectrochemistry…
The temperature dependence of the X- and Q-band EPR spectra of Cs(2)[Zn(H(2)O)(6)](ZrF(6))(2) containing approximately 1% Cu(2+) is reported. All three molecular g-values vary with temperature, and their behavior is interpreted using a model in which the potential surface of the Jahn-Teller distorted Cu(H(2)O)(6)(2+)…
A unique nonwoven 3D fabric-forming process, designed to bind a set of linear yarns that is arrayed in either uniaxial or multiaxial orientation, was identified, characterised and termed noobing five years ago. The produced 3D fabric, usually intended for composite materials application, is layerless and comprises cri…
The perovskite-type compounds Ba2LnReO6 (Ln = Y, Nd, Sm–Lu) have been synthesized. Powder X-ray diffraction measurements and Rietveld analysis show that they are monoclinic with space group P21/n and that Ln3+ and Re5+ ions are structurally ordered. Anomalies are found in their magnetic susceptibility and specific hea…
Numerical methods to predict the solubility of anthracene in mixed solvents have been proposed. A minimum number of 3 solubility data points in sub-binary solvents has been employed to calculate the solvent-solute interaction terms of a well established colsolvency model, i.e. the combined nearly ideal binary solvent/…
Recently, a new class of copolymers, so-called protein-like copolymers has been predicted theoretically by computer simulation. In these copolymers, the conformation of the copolymer determines the exposure of certain comonomer units to the outer solution. Depending on the conformation, copolymer molecules with essent…
We have shown for the first time experimentally that the O2 and O4 sites of uracil have different proton affinities, and as implied in previous computational studies, the O4 is more basic and would be energetically preferred in an orotate ribose 5'-monophosphate decarboxylase catalysis mechanism involving proton trans…
The synthesis of mesoporous silicas in the presence of the dicationic gemini surfactant [CH3(CH2)15N(CH3)2(CH2)3N(CH3)3]Br2 (C16-3-1) has been investigated at low temperatures (−4 °C) under basic and acidic conditions. Under basic conditions, the SBA-2 phase (based on a close-packed arrangement of micelles and exhibit…
The quality of work rolls that come into direct contact with the steel product has a direct effect on product quality and mill operation. A forged steel with a chromium content of 5 mass% has been conventionally used to meet the requirement of metallurgical structure homogeneity and high hardness for work rolls in col…
The binding of TSPP by a dithienylethene-tethered beta-cyclodextrin dimer can be altered reversibly by irradiation with light.
In this paper we report on experiments performed to estimate the non-locality of the photothermal non-linearity in thick dye-doped nematic liquid crystal (DDNLC). We have studied the interaction of two counter-propagating self-focused laser beams parallel to each other. From this experiment, a rough estimation of the…

As we enter this new century, it is striking how the number of applications for ozone is growing. During ozone's first century, the emphasis for using it involved primarily, potable water treatment, wastewater treatment, bottled water treatment, odor control and medical therapy. Of these, potable water and wastewater…
In this volume, regarded as a supplement to the Desk Handbook: Phase Diagrams for Binary Alloys published in 2000, the editor has included all the information available on limited solubility in every binary system. While the smaller format of the desk handbook served well in providing overall information, the range of…
We investigate the behavior of NiTi porous alloys, possessing the property of shape memory, by using different characterization methods XPS, Auger, DSC and SEM. The study mainly focuses on the determination of porosity, surface characteristics and the phase transformation. In the case of porous material the biomechani…
