Layered double hydroxides recovered after exfoliation have been characterized by solid state chemistry techniques. The nature of the recovered materials is highly dependant on the drying process; when gently dried, a well-ordered phase is obtained, either by freeze-drying or reconstruction, but the material becomes am…
This paper describes briefly the main ageing and failure mechanisms and will indicate the advantages and limitations of the diagnostic tests available for the different insulation systems used in distribution and transmission cable systems. SC21 of CIGRE has addressed the subject of ageing factors and diagnostics of c…
The phase equilibria, the martensitic and magnetic phase transformations in the β (B2) phase region of the Co–Ni–Ga and Co–Ni–Al systems have been investigated. It is shown that some compositions in the range Co–(15–30)at%Ni–30 at%Ga and Co–(30–40)at%Ni–30 at%Al exhibit both the β to β′ (L10) thermoelastic martensitic…
Hollow microspheres with ordered mesoporous walls are synthesised under ambient conditions by a simple procedure involving dilution and neutralisation of an aqueous tetraethoxysilane/cetyltrimethylammonium bromide reaction mixture.
Specific organization of gold nanorods into anisotropic 3D-aggregates is obtained by DNA hybridisation.
This is a comprehensive source of information on all aspects of fire retardancy. Particluar emphasis is placed on the burning behaviour and flame retarding properties of polymeric materials and textiles. It covers combustion, flame retardants, smoke and toxic products generally and then goes on to concentrate on some…
Conjugated polymers in the nondoped and doped conducting state have an array of potential applications in the microelectronics industry. Conducting polymers are effective discharge layers as well as conducting resists in electron beam lithography, find applications in metallization (electrolytic and electroless) of pl…
The removal of copper oxide using acetic acid at low temperatures was investigated. Acetic acid removes a variety of copper oxides, including cuprous oxide, cupric oxide, and cupric hydroxide without attacking the underlying copper film. The removal of these oxides was determined by X-ray photoelectron spectroscopy. A…
We show that electric current can be generated in metallic carbon nanotubes immersed in liquids flowing along them. Molecular layers of the liquid coat the nanotube, slip along its surface, and excite there a phonon wind, which drags free carriers in the tube. The induced electric current should allow building of nano…
A variety of interfaces relevant to corrosion processes were examined by the scanning Kelvin probe force microscopy (SKPFM) technique in order to study the influences of various parameters on the measured potential. SKPFM measurements performed on AA2024-T3 after solution exposure showed that surface composition is no…
Composite materials containing amorphous Cu nanoparticles and nanocrystalline Cu2O embedded in polyaniline matrices have been prepared by a sonochemical method. These composite materials were obtained from the sonication of copper(II) acetate when aniline or 1% v/v aniline–water was used as solvent. Mechanisms for the…
We describe the synthesis and properties of a new class of lithium salts in which the anions are dicarboxylic acid derivatives of orthoborate. The single negative charge of these anions is shared by eight oxygen atoms (more accurately four oxygen atoms and four carbonyl groups), hence it is very spread out, and the co…
The use of halloysite clay as a low cost alternative to more traditional microencapsulation systems is reported. Halloysite is an alumino-silicate clay which demonstrates a predominately cylindrical geometry, uniquely characterized by a hollow core or series of voids with diameters ranging from 16-50 nm. These nanosca…
We calculate the distribution of interparticle normal forces P(F) near the glass and jamming transitions in model supercooled liquids and foams, respectively. P(F) develops a peak that appears near the glass or jamming transitions, whose height increases with decreasing temperature, decreasing shear stress and increas…
The corrosion behavior of as-cast magnesium alloys (AM50, AZ91, and AZ91Si) was investigated in a 0.1 M sodium sulfate solution at the corrosion potential using electrochemical impedance spectroscopy. Transmission electron microscopy was used to analyze the corrosion product layer, and phase shifting interferometric m…

Ten zirconia powders have been characterized by XRD, FT-IR/FT-FIR and Raman skeletal spectroscopies and DR-UV electronic spectroscopy. The vibrational features of a yttria-stabilized cubic zirconia and of tetragonal, monoclinic and tetragonal + monoclinic pure zirconia mixtures have been discussed. Assignments for the…
In this study, the performance of a polyaniline (PANI) based supercapacitor where electroactive PANI films were prepared on carbon paper electrodes from a nonaqueous solution with an organic acid as the proton source was investigated. The use of nonaqueous media as electrolyte led to an increase of the electroactivity…
The individual contributions of Gadolinium and Yttrium to age hardening and high temperature strength of magnesium alloys containing both elements are investigated using alloys containing different Gd:Y mole ratios of 1:0, 3:1, 1:1, 1:3 and 0:1 with a constant Y+Gd content of 2.75 mol%. All investigated alloys exhibit…
