1. Atmospheric corrosion of Nylon 6,6 in Mauritius
ABSTRACT Plastics are being more and more commonly used for outdoor applications in Mauritius. In this context, the atmospheric corrosion degradation behaviour of nylon 6,6 was observed in the Mauritian atmosphere, having a corrosivity category of C3, according to ISO 9223. The crack width, depth and extent of the cracks formed on the surface were investigat

2. Photodegradation of a polypropylene filled with lanthanide complexes
This research aims at studying the photodegradation of a polypropylene formulation filled with lanthanide complexes. These complexes can be used as tracers for the identification of polymer materials in order to facilitate an high speed automatic sorting of plastic wastes for an economically efficient recycling. By paying attention to the evolution of carbon

3. Degradation study of polypropylene (PP) and bioriented polypropylene (BOPP) in the environment
Polymers are vastly employed for numerous purposes in different industrial segments and generate soaring quantities of discarding in the environment. This research analyzed the degradability/biodegradability of polypropylene films (PP) and Bioriented polypropylene (BOPP) polymers after 11 months interred in the São Giácomo landfill in Caxias do Sul. Compar

4. NUMERICAL MODELING OF OPTICAL BEAMS GENERATED BY CHAINS SEALING OF CIRCULAR / MODELAGEM NUMERICA DE FEIXES ÓPTICOS GERADOS POR CADEIAS DE FENDAS CIRCULARES
Estudo de feixes gerados por difração em arranjos de várias fendas circulares, aqui denominadas de cadeias. Essas cadeias podem ser abertas ou fechadas e as fendas circulares ter seus centros posicionados ao longo de uma curva geratriz que definirá o formato da cadeia. Se os centros das fendas circulares estiverem distribuídos ao longo de uma circunfer�

5. Chains of magnetite crystals in the meteorite ALH84001: Evidence of biological origin
The presence of magnetite crystal chains, considered missing evidence for the biological origin of magnetite in ALH84001 [Thomas-Keprta, K. L., Bazylinski, D. A., Kirschvink, J. L., Clemett, S. J., McKay, D. S., Wentworth, S. J., Vali, H., Gibson, E. K., Jr., & Romanek, C. S. (2000) Geochim. Cosmochim. Acta 64, 4049–4081], is demonstrated by high-pow
