Novel Hierarchical Micro/Nano Modified Surfaces for Dental Implants
Journal Title: Acta Marisiensis. Seria Technologica - Year 2018, Vol 15, Issue 1
Abstract
Present paper presents the modification at nano scale level of the surfaces of Ti6Al4V alloy that were previously modified at micro scale level by acid etching (AE) or by sand blasting with large grit and acid etching (SLA). Continuous, self-ordered nanostructured (nanoporous/nanotubular) oxide layers superimposed onto micro rough topographies were developed by using electrochemical anodization in fluoride based solutions, and optimized process parameters. Novel hierarchical micro/nano modified surfaces, with well developed oxide nanotubes of 40-110 nm in diameter, were synthesis by anodization in 1M H3PO4 + 0.4 wt% HF electrolyte, at anodization potential of 24 V, applied with a potential ramp of 0.08 V/s.

Data Acquisition and Control Simulation
The aim of this paper is to build a master application that controls a brake test system. One crucial step is developing a data acquisition and control system, capable of simulating the real physical stand. The simulator...
What Does Engineering Ethics Involve?
This paper aims at elucidating and concluding information on engineering ethics, rights of engineers versus employee rights. This theoretical objective was achieved by the bibliographic study of some reference works in t...
Mathematic Modeling of Experimental Results on the Influence of Some Factors on Rape Production (Brassica Napus)
This article discusses the nonlinear regression model, the method of the smallest squares with examples, and it includes calculations for the quadratic function model. We used data obtained from a study which analyzed th...
Distribution Network Reconfiguration for Power Loss Minimization and Voltage Profile Enhancement Using Ant Lion Algorithm
Distribution networks are designed as a ring and operated as a radial form. Therefore, the reconfiguration is a simple and cost-effective way to use existing facilities without the need for any new equipment in distribut...
An exemplified introduction of the Laplace transform
We solve a linear Cauchy problem with discontinuous perturbation two ways, by solving continuous Cauchy problems successively and by using Laplace transform. An example is given when the last one cannot be used any longe...
