The Trypanosoma cruzi Surface, a Nanoscale Patchwork Quilt
(Cell Press, 2017-02-01)
The Trypanosoma cruzi trypomastigote membrane provides a major protective role against mammalian host-derived defense mechanisms while allowing the parasite to interact with different cell types and trigger pathogenesis. ...
Microstructure homogeneity of milled aluminum A356-Si3N4 metal matrix composite powders
(Elsevier Editora Ltda, 2019)
A metal matrix composite was produced by co-milling an A356 aluminum alloy powder obtained by rotating electrode off-equilibrium solidification, with different mass fractions (10, 20 and 30%) of Si3N4. The structural and ...
Buckybomb: Reactive Molecular Dynamics Simulation
(Amer Chemical Soc, 2015-03-05)
Energetic materials, such as explosives, propellants, and pyrotechnics, are widely used in civilian and military applications. Nanoscale explosives represent a special group because of the high density of energetic covalent ...
Crystallization study of the (1-x)Sb2O3-(x)SbPO4 glass system
(Elsevier B.V. Sa, 2008-12-20)
Antimony-based glasses have potential applications for all optical switching devices as well as for photosensitive materials. In both applications, the presence of a nano-scale antimony phase, inside the glass matrix, may ...
A three-dimensional nanoscale study in selected coal mine drainage
(Universidad de la Costa, 2020)
Ultrafine-grained Al composites reinforced with in-situ Al3Ti filaments
(Elsevier Science Sa, 2016-01)
Ultrafine-grained (UFG) Al matrix composites reinforced with 15 and 30vol% in-situ Al3Ti filaments were fabricated by extrusion of Al-Ti powder mixtures followed by solid-state reactive diffusion. Fine Al powder particles ...
Nanofibrillated cellulose and cellulosic pulp for reinforcement of the extruded cement based materials
(Elsevier B.V., 2018-01-30)
The use of cellulose nanofibers as reinforcement may contribute for improving particle packing and decrease the crack growth rate of composites at nanoscale. Additionally, the high specific surface area of cellulose ...
Vegetable fiber as reinforcing elements for cement based composite in housing applications - A Brazilian experience
(2018-02-14)
Vegetable fibers are a hierarchical structure material in the macro, micro and nanometric scales that have been used as reinforcement in cementitious materials. In nanoscale, the nanofibrillated cellulose has the advantage ...
Composites and Nanocomposites Based on Starches: Effect of Mineral and Organic Fillers on Processing, Structure, and Final Properties of Starch
(Elsevier, 2017)
Composites development, by incorporating organic or mineral fillers to starch matrices, can be used to improve their final properties. Accordingly, composites of different starch matrices reinforced with organic fillers, ...
Synthesis of new antibacterial composite coating for titanium based on highly ordered nanoporous silica and silver nanoparticles
(Elsevier, 2014)
Infection is the most common factor that leads to dental titanium implant failure. Antibacterial implant surfaces based on nano-scale modifications of the titanium appear as an attractive strategy for control of peri-implantitis. ...
