Modelling colour changes during the caramelisation reaction

Multiresponse modelling of the caramelisation reaction

Under the conditions used to prepare the traditional sugar syrups and caramels, commercial sucrose is heated with small amounts of water in order to attain supersaturated (at room temperature) solutions. Undesuch conditions, a lag phase in sucrose thermal degradation was experimentally observed. This lag phase was also observed in the formation of reaction products, and can be interpreted has a...

Modelling Temperature Dependency of Silicon Nitride Formation Kinetic during Reaction Bonded Method

An accurate prediction of reaction kinetics of silicon nitridation is of great importance in designing procedure of material production and controlling of reaction. The main purpose of the present study is to investigate the effect of temperature on the kinetics of reaction bonded silicon nitride (RBSN) formation. To achieve this, nitrogen diffusion in the silicon nitride layer is considered as...

Dynamic modelling of hardness changes of aluminium nanostructure during mechanical ball milling process

In this research, the feasibility of using mathematical modelling in the ball milling process has been evaluated to verify the hardness changes of an aluminium nanostructure. Considering the model of normal force displacement (NFD), the radius of elastic-plastic and normal displacement of two balls were computed by applying analytical modelling and coding in MATLAB. Properties of balls and alum...

A Visual Survey of Colour on Paper and Colour Changes During Exposure to Light

This paper presents how inkjet colour is affected by firstly the substrate and secondly exposure to light and the combination of both. The research uses both pigmented and dye based inks printed onto coated and uncoated fine art papers, and are subjected to light conditions that are constantly changing through out the day and consequently the year. Although benchmark conditions and standards as...
