Electrochemical noise (EN) data is commonly used to monitor corrosion of metals in various environments. In this work we use recurrence quantification analysis (RQA) to study EN time series of stainless steel AISI 316 samples immersed in a mildly corrosive electrolyte. It is found that RQA of current and potential tim…
The concept of using cellulose as a smart material for preparing electro-active paper (EAPap) has been a land mark discovery, since it exhibits an impressive magnitude of actuation at relatively modest voltages. Considering the small thickness of cellulose samples (35 mum) and smaller depth of electrodes (100 nm), eve…
The influence on the optical properties of cholesteric liquid crystal displays (LCDs) was examined for neutral molecule binding by mesogen/receptors in the mesomorphic phase. The motivation was to prepare neutral molecule sensors that use a colour change to signal analyte binding. A receptor that binds barbiturate ana…
The effect of exchange cations (Mn+: Li+, Na+, K+, NH 4 + , Ca2+, Mg2+, Fe3+, and Al3+) and thermal treatment on the physicochemical properties of smectite was investigated. Before thermal treatment, unheated (25°C) Mn+-smectite showed increased d 001 spacing upon glycol solvation; after heating at 300°C or above (400…
Abstract Gold nanoplates mixed with spherical nanoparticles were prepared in lecithin lamellar liquid crystals containing non‐ionic surfactants as reductant. The effects of the concentrations of surfactants, reactants and salt on the formation of the nano‐products are discussed. The selective adsorption of lecithin he…
Single crystals of K 1- x Li x TaO 3 (KLT) with different Li concentrations are grown by the self-flux method. Li concentrations in the crystals are determined by second-harmonic-generation microscope observations. Complex dielectric constants of KLT are measured in the temperature range from 20 K to room temperature…
A comprehensive investigation of the electro- and thermophysical properties of the manganite La0.8Ag0.15MnO3 is carried out over a wide temperature interval (4.2–350K) and in magnetic fields up to 26kOe. It is shown that the colossal magnetoresistance in a magnetic field of 11kOe amounts to 57%, and the effect is maxi…
Abstract Hydrogen permeation of 16Mn steel under a cyclic wet–dry condition was investigated by Devanathan–Stachurski's electrolytic cell with a membrane covered on the exit side by a nickel layer and the weight loss was measured for each wet–dry cycle. The results show that hydrogen permeation current change with dif…
We present a novel interpretation of defected tubes based on a dislocation model. A scroll (a sheet rolled without closure) is considered as an axial edge dislocation in a multiwall nanotube (MWNT). Screw dislocation type defects separate scroll from nested-tubes within the same nanotube. The glide of the screw disloc…
Abnormal grain growth (AGG) proceeds in case that normal grain growth is inhibited. It has long been known that the inhibition involves finely dispersed particles and/or the development of specific textures. There is another strong obstacle against the grain boundary (GB) motion; the solute atoms can reduce their ener…
The chemical composition and the leachability of heavy metals in municipal solid waste incinerator (MSWI) fly ash were measured and analysed. For the leachability of unstabilized MSWI fly ash it was found that the concentrations of Pb and Cr exceeded the leaching toxicity standard. Cementitious solidification of the M…
The modified molecular structural mechanics method (MMSMM) is extended to analyze the dynamic characteristics of single-walled carbon nanotubes (SWCNTs). In MMSMM, the deformation potential of SWCNT is decomposed and it can be easily expressed as the function of the positions of carbon atoms in molecular mechanics, an…
Abstract The tetranuclear nickel(II) complexes [(LNi II 2 ) 2 (acetylenedicarboxylate)][BPh 4 ] 2 ( 2 [BPh 4 ] 2 ), [(LNi II 2 ) 2 (terephthalate)][BPh 4 ] 2 ( 3 [BPh 4 ] 2 ), and [(LNi II 2 ) 2 (isophthalate)][BPh 4 ] 2 ( 4 [BPh 4 ] 2 ), where L 2– represents a macrocyclic hexaaza‐dithiophenolate ligand, have been sy…

The present paper examines the development of grain size during the recrystallization of magnesium alloys and the influence the grain size has on the mechanical response. In magnesium alloys grain refinement improves the strength-ductility balance. This simultaneous increase in both strength and ductility is ascribed…
Many fibrous materials such as nonwovens are consolidated via compaction rolls in a so-called calendering process. Hot rolls compress the fiber assembly and cause fiber-to-fiber bonding resulting in a strong yet porous structure. In this paper, we describe an algorithm for generating three dimensional virtual fiberweb…
Photochromic chiral azobenzene compounds with different molecular structures were synthesized, and a cholesteric phase was induced by mixing each chiral azobenzene compound with a non‐photochromic chiral compound in a host nematic liquid crystal, E44. Helical pitch and, thus, helical twisting powers (HTP) of the chira…
Abstract Carboxymethyl starch (CMS, DS CM 0.1) was modified with octenylsuccinic anhydride in various solvent systems. Using the dimethyl sulphoxide (DMSO)/ p ‐toluenesulphonic acid ( p ‐Ts‐OH) system, carboxymethyl starch octenylsuccinates (OS‐CMS) were obtained with degrees of substitution (DS) ranging from 0.03 to…
Samples in the system SrSn1−xTixO3 were prepared by conventional solid state ceramic route for 0≤x≤0·50. Powder X-ray diffraction was performed to confirm formation of single phase solid solution. It has been found that solid solution forms only up to x=0·40. DC resistivity and Seebeck coefficient α were measured to u…
Abstract The resistance to localized corrosion of three austenitic stainless steels (SS), specifically the ASTM F‐138 which is widely used in several biomedical applications, the DIN 1.4460 high N, and the DIN 1.4970 was investigated in this study by electrochemical techniques including potentiodynamic polarization an…
