Counter diffusion chemical vapour deposition (CVD) is an excellent way to prepare inorganic thin films or membranes on the surface of porous or non-porous supports. Modification of the pore size of porous supports by this method to prepare molecular-sieve membranes is another interesting opportunity. However, control…

Because of several technical and economical advantages XLPE (cross-linked polyethylene)-insulated power cable systems are increasingly used in the high voltage (HV) and extremely high voltage (EHV) range. High voltage XLPE-insulated cables consist of a copper or aluminium conductor (inner conductor), a semiconducting…

Dermal sheep collagen was crosslinked with 1,4-butanediol diglycidyl ether (BDDGE) or modified with glycidyl isopropyl ether (PGE). The reduction in amine groups as a function of time was followed to study the overall reaction kinetics of collagen with either BDDGE or PGE. Linearization of the experimental data result…

Dynamic compression tests were performed by means of a Split Hopkinson Pressure Bar (SHPB). Test materials were 2124Al alloys reinforced with 17% volume fraction of 3, 13 and 37 μm SiC particles, respectively. Under strain rate ε = 2100 l/s, SiC particles have a strong effect on σ 0.2 of the composites and the σ 0.2 i…

The first photophysical studies of a member of the family of subnaphthalocyanines are described. The cone-shaped unsubstituted subnaphthalocyanine, synthesized in 35% yield, provides it with distinctive photophysical properties that are better than those of the related planar phthalo- and naphthalocyanines. SubNc abso…

The equation of state of a dry foam with ideal gas in the bubbles, proposed by Ross, is proved. This equation suggests that a foam with a free boundary will expand to a maximum volume if the external pressure is lowered at constant temperature. The same foam enclosed in a container, on the other hand, can be expanded…

Scleractinian skeleton is composed of mineral and organic phases. Using staining tech− niques (acridine orange dye) Johnston’s (1980) pioneering observations of intraskeletal organic envelopes in Pocillopora damicornis coralla can be extended to two other coral reef genera i.e., Acropora and Favia. The concept of biol…

SUMMARYThe influences of various pre-treatments of interest in adhesive bonding on the surface condition of 2024-T3 alloy have been examined. In particular, the morphologies of films formed during alkaline etching (NaOH), electropolishing (perchloric acid/ethanol), acid pickling (Na2Cr2O7/H2SO44 and anodzing (H3PO4),…

The behavior of crosslinked polyethylene (XLPE) for HV cable insulation under electrical stress is discussed in the paper, referring to specimens unaged and electrically aged. Polarization and space charge features are considered. The behavior of the examined insulation is evaluated through the 'universal' model for p…

An unidentified phase X of 1,4-dialkyl-1,4-diazoniabicyclo[2.2.2]octane dibromides reported by Nogami et al. in 1985 was reinvestigated by differential scanning calorimetry, polarizing microscopy and temperature-dependent X-ray diffraction. The X phase was thus established as a smectic tetragonal (ST) mesophase which…
