An Evaluation of Tellurium Compounds as Polymer Stabilisers
… on PVC during processing, thermal ageing and UV irradiation was examined by measuring unsaturation, colour and carbonyl formation. These compounds were found to be effective stabilisers during processing and thermal oxidation but they do not lead to good UV stability during photo-oxidation. …

Functional characterization of pH and ultrasound treated soy protein based nanoemulsions with lutein
… freeze dried, and the characteristics such as UV stability, in vitro bioaccessibility of both original and freeze-dried and resuspended nanoemulsions (SEOF and SEEF) were studied. Particle size in soy nanoemulsions ranged from 99-127 nm. Lutein in both SEO and SEE formulations showed improved …

Stabilization of resveratrol through microencapsulation and incorporation into food products
… benefits to consumers. Challenges such as instability in environmental conditions and the digestive system, as well as negative sensory properties of the bioactive compounds limits the addition of these compounds to food products. Encapsulation is a processing technique that can help to …

Bio-composites materials from engineered natural fibres for structural applications
… It has high stiffness, strength, thermal and UV stability, but is low in toughness. Limited applications of natural fibre reinforced PLA composites so far is mainly due to low mechanical properties of discontinuous fibre composites made using injection moulding or compression moulding using …
