The conversion of the petrochemical polymer polyethylene terephthalate (PET) to a biodegradable plastic polyhydroxyal-kanoate (PHA) is described here. PET was pyrolised at 450 degrees C resulting in the production of a solid, liquid, and gaseous fraction. The liquid and gaseous fractions were burnt for energy recovery, whereas the solid fraction terephthalic acid (TA) was used as the feedstock ...
Kinetics of co-polyesters of hydroquinone diacetate and its methyl derivative with terephthalic acid
A new approach to formulating pyrotechnic materials is presented whereby constituent ingredients are bound together in a solid-state lattice. This reduces the batch inconsistencies arising from the traditional approach of combining powders by ensuring the key ingredients are 'mixed' in appropriate quantities and are in intimate contact. Further benefits of these types of material are increased ...
Abstract There is growing interest in biodegradable and bio‐based materials that can replace conventional plastics applications such as packaging. Polymers based on 2,5‐furandicarboxylic acid (FDCA) have been proposed analogues for polymers terephthalic acid. However, they tend to be brittle, exhibit limited biodegradability, there are few examples of biocomposites from these polymers. Describe...
Nanocrystalline Sr1-x Bax SnO3 (x=0, 0.2, 0.4, 0.8, 1) perovskite photocatalysts were prepared by microwave synthesis in an ionic liquid (IL) and subsequent heat-treatment. The influence of the Sr/Ba substitution on the structure, crystallization, morphology, and photocatalytic efficiency was investigated and the samples were fully characterized. On the basis of X-ray diffraction results, as th...
