Performance characteristics of fiber modified hot mix asphalt
(Elsevier B.V., 2018-07-10)
A mixture of polypropylene and aramid fibers was used in this study to evaluate the performance characteristics of a modified asphalt mixture. A conventional dense-graded hot mix asphalt (HMA) used in Sao Paulo, Brazil was ...
Fracture behavior of recyclable all-polypropylene composites composed of α- and β-modifications
(Sage Publications Ltd, 2011-11)
The fracture behavior of all-PP composites was studied under quasi-static loading conditions. Fracture toughness was evaluated by means of different fracture mechanics approaches depending on materials’ behavior. Composites ...
Uni and biaxial impact behavior of double-gated nanoclay-reinforced polypropylene injection moldings
(John Wiley & Sons Inc, 2012-09-17)
Polypopylene/nanoclay three-dimensional parts were produced without intermediate steps by direct injection molding to explore the influence of flow features and nanoclay incorporation in their impact performance. The ...

Aesthetic correction of a hypertrophic sinus frontalis: A long-term follow-up evaluation and refinement of the method
(Springer, 2006-12-01)
Two cases treated for hypertrophy of the frontal sinus are presented. In both patients, the excised frontal bone was inverted, and the resultant cavity was filled with either bone dust from the parietal region or Medpor. ...
Polymer Photodegradation Followed by Infrared: A Tutorial
(Brazilian Chemical Soc, 2020-07-01)
Since the first scientific study published by August Wilhelm Hofmann at 1861, where he found the role of oxygen in the degradation of weathered materials, a lot of progress has been made regarding the understanding of the ...
Propylene/1-hexene copolymer as a tailor-made poly(propylene) for membrane preparation via the thermally induced phase separation (TIPS) process
(WILEY-V C H VERLAG GMBH, 2006-02-10)
Poly[propylene-co-(1-hexene)], one example of a "tailor-made poly(propylene)", was synthesized using an iso-specific metallocene catalyst in order to study the influence of copolymer composition on the pore size of isotactic ...
