MnO2 Nanoscale Interface Modification
<p>Interface modification of carbon fibers has been shown to improve the mechanical performance of composites. In addition, interface modification of carbon fiber composites can impart multifunctionality into the resulting composite. This work will explore ZnO and MnO2 as interface modifications …

Cognitive Bias Modification & Exercise
… orientated Cognitive Interpretation Bias Modification (CBM-I) training programme that’s positively valanced and incorporating a dual method of CBM-I and exercise training against a rest control group. Study four uses the same methodological paradigm as study three whilst introducing a more …

Chemical modification of polymers
… of PVC degradation and stabilisation, chemical modifications were imposed on degraded PVC and raw PVC with the aim of obtaining non-migrating additives. The modifications were carried out mainly in the presence of dibutyl maleate (DBM), and the resulting polymer contained dibutyl maleic …

Ca2+ dependant synaptic modification
… influx. By using this method, we found 1. that modification of synaptic strength has a bell-shaped dependency to the amount of Ca2+ influx, 2. that weak Ca2+ current through desensitized NMDA receptors sustained for a long period of time (160 ms) generates LTD, 3. evidence that phosphorylation …

Commissioning genetic modification: The marginalisation of dissent in the royal commission on genetic modification
The Royal Commission on Genetic Modification (RCGM) appeared to be a 'public debate'. It sought the participation of people from a cross-section of society according to its broad terms of reference, and invited input on 'options' for the nation. The majority of the public and special interest …

Laser surface modification of steel
… work is an investigation of the laser surface modification of H13 tool steel using pulse laser processing mode. Initial screening experimental designs conducted lead to more optimised detailed designs. A carbon dioxide (CO2) laser system with 10.6 μm wavelength was used. In the experimental …

Ultrasonic Modification of Condensation Processes
Condensation processes of a thin metal film are a direct result of interfacial energies. The realationships between these energies are virtually identical to those between an adhesive that wets a solid substrate. Using adhesion as a model, a method of modifying the interfacial energies of a gold on …

Chemical modification of smectite clays
Today, speciality use organoclays are being developed for an increasingly large number of specific applications. Many of these, including use in cosmetics, polishes, greases and paints, require that the material be free from abrasive impurities so that the product retains a smooth `feel'. The …

Interlamellar modification of smectite clays
… within the clay. Two methods of interlamellar modification were identified which lead to enhanced conductivity of laponite, namely ion exchange and tin(IV) oxide pillaring. A monoionic potassium exchanged laponite shows a four fold increase in a.c. conductivity compared to sodium exchanged …

Enzyme catalysed modification of polymers
… project was to investigate the enzyme catalysed modification of synthetic polymers. It was found that an immobilised lipase from Candida antartica (Novozyme 435) catalysed the selective epoxidation of poly(butadiene) in the presence of hydrogen peroxide and catalytic quantities of acetic acid. …

Mesh modification using deformation gradients
Computer-generated character animation, where human or anthropomorphic characters are animated to tell a story, holds tremendous potential to enrich education, human communication, perception, and entertainment. However, current animation procedures rely on a time consuming and difficult process …
