Influence of gamma radiation on properties of common Brazilian wood species used in artwork
Woods, as other materials, are susceptible to alterations in their internal structure because of physical, chemical or biological agents. Wood can be considered a natural composite with high strengthExpand

Enzymatic degradation of poly (ε-caprolactone) and cellulose acetate blends by lipase and α-amylase
Abstract Films of poly( e -caprolactone) (PCL) and cellulose acetate (CA) containing different proportions of PCL/CA (100/0, 80/20, 60/40, 40/60, 20/80 and 0/100, w/w) were prepared by casting, andExpand

Mechanical, thermal and morphological characterization of polypropylene/biodegradable polyester blends with additives
Abstract The (bio)degradation of polyolefins can be accelerated by modifying the level of crystallinity or by incorporation of carbonyl groups by adding pro-oxidants to masterbatches or throughExpand

Evaluation of the effects of gamma radiation on thermal properties of wood species used in Brazilian artistic and cultural heritage
The wood is considered a natural composite of extreme complexity, mainly composed of cellulose, lignin, hemicellulose (polyposis), and extractives. Its composition encourages biological attacks fromExpand
