1. Thermal Barrier Coatings : Durability Assessment and Life Prediction
Abstract : Thermal barrier coating (TBC) systems are coating systems containing a metallic bond coat and a ceramic top coat. TBCs are used in gas turbines for thermal insulation and oxidation resistance. READ MORE

2. Barrier Properties of greaseproof paper
Abstract : The barrier properties of greaseproof paper are achieved by extensive beating of the fibres. This treatment results in high costs for energy, both as beating energy and drying energy. A full-scale trial has been performed to investigate the role of the pulp with respect to energy demand and the barrier properties of the final papers. READ MORE

3. Alternative methods for analysing moisture transport in buildings : Utilisation of tracer gas and natural stable isotopes
Abstract : New methods, based on tracer gas measurements and isotopicanalysis can be used to evaluate the moisture properties ofbuilding materials and provide the means for forensic analysisof the origins and history of excessive water in buildings, theimmediate practical consequences of which will be the abilityto improve the moisture performance of constructions. It is shown, in theory and through measurements how thewater vapour permeability of porous building materials can witha good degree of accuracy be estimated with tracer gasmeasurements that provide an efficient alternative to the cupmethod.

4. Thermal Barrier Coatings for Diesel Engines
Abstract : Reducing the heat losses in heavy-duty diesel engines is of importance for improving engine efficiency and reducing CO2 emissions. Depositing thermal barrier coatings (TBCs) onto engine components has been demonstrated to have great potential to reduce heat loss from the combustion chamber as well as from exhaust components.

5. Enhancement and Characterization of Films for Barrier and Release Applications
Abstract : Films and coatings can improve the quality and shelf-life of food products by acting as barriers to e.g. water vapour and oxygen. Many edible biopolymer films, based on polysaccharides and proteins, form excellent oxygen barriers but most often provide only poor water vapour barriers. READ MORE
