1. Wear behavior of Diamond-like Carbon Deposited on Ti6Al4V Prepared with Surface Mechanical Attrition Treatment
Surface modification by deposition of hard coatings is a way to overpass the poor wear resistance of some metallic materials and one potential material is the Diamond-Like Carbon (DLC). We investigated the wear behavior, and the adhesion of the DLC deposited on a Ti6Al4V (Ti64) alloy after Surface Mechanical Attrition Treatment (SMAT). The SMAT was applied u

2. Síntese e caracterização de pós de fosfato tricálcio-β e de hidroxiapatita: elaboração de bifásicos HA/TCP-β para aplicações como substituto ósseo / Synthesis and characterization of powders of β -Tricalcium phosphate and hydroxyapatite: elaboration of HA/β -TCP biphasic for applications as bone substitute
The treatments of bone loss are current topics of research. The materials that stand out in the treatments of reconstruction and formation of new bone tissue, are the hydroxyapatite, the α and/or β calcium phosphates, and biphasic hydroxyapatite / α and/or β calcium phosphate. It is known from literature that these biomaterials h

3. Analysis of tool wear, surface roughness and cutting power in the turning process of compact graphite irons with different titanium content
Due to its good mechanical properties, the Compacted (Vermicular) graphite cast iron (CGI) has found a lot of applications in the automobilistic field. One of the applications is the production of high power diesel engine blocks that, due to the higher strength compared to the usual gray cast iron, allows the increase of the pressure inside the cylinder and,

5. Atrito de particulas solidas de cloreto de sodio (NaCl) em leite fluidizado gasoso / Attrition of solid particles of sodium chlroide (NaCl) in gas-fluidized bed
O atrito de sólidos particulados é um problema enfrentado pelas indústrias que utilizam leito fluidizado parcialmente ou na totalidade de seus processos, tais como petroquímicas e farmacêuticas. Tal atrito é caracterizado pela ruptura ou desgaste involuntário das partículas durante a manipulação, processamento e armazenamento dos sólidos, sendo es

6. Telomere attrition and Chk2 activation in human heart failure
The “postmitotic” phenotype in adult cardiac muscle exhibits similarities to replicative senescence more generally and constitutes a barrier to effective restorative growth in heart disease. Telomere dysfunction is implicated in senescence and apoptotic signaling but its potential role in heart disorders is unknown. Here, we report that cardiac apoptosis
