Hemostasis-on-a-chip: Impedance spectroscopy meets microfluidics for hemostasis evaluation
(2019-08-14)
Article
Open AccessIn the case of vascular injury, a complex process (of clotting) starts, involving mainly platelets and coagulation factors. This process in healthy humans is known as hemostasis, but when it is deregulated (thrombosis), ... -
Effect of grain size and density of abrasive on surface roughness, material removal rate and acoustic emission signal in rough honing processes
(Multidisciplinary Digital Publishing Institute (MDPI), 2019-08-01)
Article
Open AccessHoning processes provide a special cross-hatch pattern to the internal surface of cylinders that favors oil flow. However, along honing operation the abrasive grains wear out and lose their ability to cut material. The ... -
The coupled effects of bending and torsional flexural modes of a high-speed train car body on its vertical ride quality
(2019-06-12)
Article
Open AccessThis study is focused on the effects of bending and torsional flexural modes of the car body on the ride quality index of a high-speed train vehicle. The Euler–Bernoulli beam model is used to extract an analytical model ... -
Laser surface texturing of alumina/zirconia composite ceramics for potential use in hip joint prosthesis
(Multidisciplinary Digital Publishing Institute (MDPI), 2019-06-06)
Article
Open AccessThe use of metal shell to fix an acetabular cup to bone in hip joint prosthesis carries some limitations, including restrictions in prosthetic femur ball diameter and in patient’s range of motion. These drawbacks could be ... -
Low temperature processing of solution-derived ceria deposits on flat surfaces of 3D-printed polyamide
(2019-06-01)
Article
Restricted access - publisher's policyDoped ceria deposits have been prepared on 3D-printed polyamide-12 components starting from inkjet-compatible solutions in an attempt to functionalize the surface of the plastic part, followed by a low temperature decomposition ... -
Enhanced fully cellulose based forward and reverse blood typing assay
(2019-05-07)
Article
Restricted access - publisher's policyThis study presents an enhanced paper-based analytical device (PAD) for forward and reverse group blood typing. The proposed PAD uses a novel methodology, which provides highly reliable results on a fully cellulose based ... -
Multicriteria analysis of renewable-based electrification projects in developing countries
(2019-01-01)
Article
Restricted access - publisher's policyThe design of wind-photovoltaic stand-alone electrification projects that combine individual systems and microgrids is complex and requires from support tools. In this paper, a multicriteria procedure is presented in detail, ... -
Wear and MnS layer adhesion in uncoated cutting tools when dry and wet turning free-cutting steels
(Multidisciplinary Digital Publishing Institute (MDPI), 2019-05-08)
Article
Open AccessFree-cutting steels are developed to produce large quantities of parts with low mechanical behavior, mainly for automotive sector. These alloys contain phosphorous, lead, sulfur, and manganese that help to improve the ... -
On the microstructure effects when using electropulsing versus furnace treatments while drawing inox 308L
(Elsevier, 2019-05-07)
Article
Restricted access - publisher's policyIn the present work, microstructure and texture evolution in a commercial 308L stainless steel wire is assessed by comparing several electropulsing configurations and thermal annealing treatments performed during and after ... -
Joining metrics enhancement when combining FSW and ball-burnishing in a 2050 aluminium alloy
(Elsevier, 2019-06-15)
Article
Open AccessThis report describes the effect of the ball-burnishing process on the mechanical properties of 2050 aluminium alloy that was previously friction stir welded. This process is a fast, environmentally-friendly and cost-effective ... -
Optimal machining strategy selection in ball-end milling of hardened steels for injection molds
(Multidisciplinary Digital Publishing Institute (MDPI), 2019-03-01)
Article
Open AccessIn the present study, the groups of cutting conditions that minimize surface roughness and its variability are determined, in ball-end milling operations. Design of experiments is used to define experimental tests performed. ... -
Comparison of mechanical and electrical characteristics of various polymers blended with ground tire rubber (GTR) and applications
(2019-04-15)
Article
Open AccessThe massive manufacture of tires and the di culty of reducing the stocks of used tires is a serious environmental problem. There are several methods used for recycling wasted tires, one of which is mechanical crushing, in ...
