The present work aimed to study the effects of kaolin-based geopolymers in epoxy-layered silicate nanocomposites using a compressive test. A series of nanocomposites with kaolin-based geopolymers containing 1-7 phr content were prepared. A qualitative evaluation of the three-dimensional shape of a kaolin-based geopolymer surface and origin was characterised using the scanning electron microscopy (SEM). It was discovered that the addition of kaolin based geopolymer at the beginning, in low phr content, displayed a lower compressive strength than nanocomposites without kaolin based geopolymer filled. However, the compressive properties unexpectedly increased at 3phr of kaolin geopolymer content compared to nanocomposites without kaolin. This illustrated that the incorporation of kaolin geopolymers in the nanocomposite system can potentially improved the mechanical properties of the epoxy resin, thereby needs further exploration.

The effect of fly ash based geopolymer in epoxy layered silicates nanocomposites was studied using a compressive test. A series of nanocomposites with fly ash based geopolymer 1-7phr content was prepared. Qualitative evaluation of the three-dimensional shape of a fly ash based geopolymer surface and the origin was characterized using scanning electron microscopy. It was found that the addition of fly ash at the beginning with lower content are showing lower compressive strength than nanocomposites without fly ash filled. However, compressive properties suddenly increased at 3phr of fly ash geopolymer content compared to nanocomposites without fly ash. This indicated the blending of fly ash geopolymer in nanocomposites system have the ability for further studies.

This article examines the relatively new fields of colour and shape trade marks. It was initially feared by some academics that the new marks would encroach on the realms of patent and copyright.  However, the traditional requirements of trade mark law, such as functionality and descriptiveness, have meant that trade marks in colour and shape are extremely hard to acquire if they do not have factual distinctiveness. As colour and shape trade marks have no special restrictions, it is proposed that the combination trade mark theory and analysis from the Diamond T case should be used as a way to make them more accessible. The combination analysis can be easily applied because every product has a three dimensional shape and a fourth dimension of colour.

Three Dimensional Shape

Perceiving the shape of three-dimensional objects is essential for interacting with them in daily life. If objects are constructed from different materials, can the human visual system accurately estimate their three-dimensional shape? We varied the thickness, motion, opacity, and specularity of globally convex objects rendered in a photorealistic environment. These objects were presented under either dynamic or static viewing condition. Observers rated the overall convexity of these objects along the depth axis. Our results show that observers perceived solid transparent objects as flatter than the same objects rendered with opaque reflectance properties. Regional variation in local root-mean-square image contrast was shown to provide information that is predictive of perceived surface convexity.
