A series of six potentially bidentate ligands composed of 5-membered heterocyclic rings with methylenepyridyl substituents are described. These molecules are potentially bifunctional, acting as bidentate ligands to metal centres whilst retaining on their periphery a range of groups capable of forming triple hydrogen b…

A simple and efficient adaptive mesh generation algorithm is proposed for the full-wave finite-element analysis of optical waveguides using edge/nodal hybrid elements. We employ a local weight defined by a difference between the fundamental and the higher order element solutions. This method can be used for both the g…

The vibrational spectrum of tetraethylorthotitanate (TET) has been assigned by using vibrational and structural data from the series Ti(OEt)yCl4 − y (y = 1 to 4), to distinguish between bands due to bridging and terminally coordinated ethoxide. EXAFS studies of the series showed an increase in association with increas…

Instrumental manipulations during minimal access surgery (MAS) are limited by the four degrees of freedom (d.o.f.) possible when long instruments are introduced into the peritoneal cavity through access ports. This is in sharp contrast to an equivalent instrument held in the hand by the surgeon during open conventiona…

Phenolic resin/silica hybrid ceramers were prepared through sol–gel technology. Differential scanning calorimetry and thermogravimetric analysis methods were utilized to study the thermal properties of the fabricated hybrid ceramers. The results showed that the heat resistance of the ceramers was slightly higher than…

A technique has been established to grow large diamonds up to 2 cm. The crystals are bulky polyhedron with yellow, blue, green or brown color as well as colorless, which depend on impurities. The impurities incorporated into the diamond are limited, i.e. nitrogen, boron, nickel, cobalt, silicon and phosphorus.

Photolysis (254–350 nm) of a variety of aroyl-substituted phenylacetic acids and p-acetylphenylacetic acid in aqueous solution at pH > pKa resulted in efficient photodecarboxylation (Φ = 0.2–0.7), to give in most cases a single product arising via the corresponding arylmethyl carbanion, indicating that photodecarboxyl…

Dynamic viscoelastic properties of binary blends consisting of an isotactic polypropylene (i-PP) and ethylene-1-octene copolymer (PEE) were investigated to reveal the relation between miscibility in the molten state and the morphology in the solid state. In this study, PEE with 24 wt % of 1-octene was employed. The PE…

Microchannels having highly enhanced surface area have been fabricated by a thin‐film deposition technique known as glancing angle deposition. Porosimetry and simulation of the microstructures was used to estimate the surface area enhancement of the new microchannels. Two distinct types of microchannels have been crea…

The differences in the polymerization abilities of N-vinylformamide (NVF) and N-vinylisobutyramide (NVIBA) and the synthesis of their copolymers were studied. The polymerization abilities were fairly good and quite similar to those of N-vinyl- acetamide (NVA), a monomer in the same class as N-vinylalkylamides. Since t…

Results from fracture toughness and tensile and delayed hydride cracking (DHC) tests on Zr-2.5Nb pressure tubes removed from CANDU power reactors in the 1970s and 80s for surveillance showed considerable scatter. At that time, the cause of the scatter was unknown and prediction of fracture toughness to the end of the…
