Alternatives for Chemical and Biochemical Lignin Valorization: Hot Topics from a Bibliometric Analysis of the Research Published During the 2000–2016 Period
(MDPI, 2018-08)
A complete bibliometric analysis of the Scopus database was performed to identify the research trends related to lignin valorization from 2000 to 2016. The results from this analysis revealed an exponentially increasing ...
New Procedure for Compacting Prismatic Specimens of Cement-Treated Base Materials
(MDPI, 2018-07)
Understanding the long-term behaviour of cement-treated base materials is a key factor to improve its design and obtain environmentally friendly pavement base materials. Their characterization requires manufacturing prismatic ...
Bitumen modified with recycled polyurethane foam for employment in hot mix asphalt
(Universidad Nacional de Colombia, 2018-04)
A wide variety of modifiers have been applied to bitumen in order to enhance their properties and performance. Among them, polymers have been mainly used. The aim of this paper is to assess the use of polyurethane foam ...
A contact mechanics study of 3D frictional conformal contact
(Elsevier, 2018-03)
A contact mechanics study of three-dimensional conformal contact with friction is presented, based on numerical calculations with Finite Element models and an extension of Kalker's exact contact theory which takes into ...
Drilling Process in γ-TiAl Intermetallic Alloys
(MDPI, 2018-11-26)
Gamma titanium aluminides (gamma-TiAl) present an excellent behavior under high temperature conditions, being a feasible alternative to nickel-based superalloy components in the aeroengine sector. However, considered as a ...
Hole Making by Electrical Discharge Machining (EDM) of -TiAl Intermetallic Alloys
(MDPI, 2018-07)
Due to their excellent strength-to-weight ratio and corrosion and wear resistance, gamma-TiAl alloys are selected for aerospace and automotive applications. Since these materials are difficult to cut and machine by ...
Improving Stability Prediction in Peripheral Milling of Al7075T6
(MDPI, 2018-08)
Chatter is an old enemy to machinists but, even today, is far from being defeated. Current requirements around aerospace components call for stronger and thinner workpieces which are more prone to vibrations. This study ...
Super Abrasive Machining of Integral Rotary Components Using Grinding Flank Tools
(MDPI, 2018-01-01)
Manufacturing techniques that are applied to turbomachinery components represent a challenge in the aeronautic sector. These components require high resistant super-alloys in order to satisfy the extreme working conditions ...
Comparison of Flank Super Abrasive Machining vs. Flank Milling on Inconel® 718 Surfaces
(MDPI, 2018-09)
Thermoresistant superalloys present many challenges in terms of machinability, which leads to finding new alternatives to conventional manufacturing processes. In order to face this issue, super abrasive machining (SAM) ...
Computational Modelling of Rectangular Sub-Boundary Layer Vortex Generators
(MDPI, 2018-01-19)
Vortex generators (VGs) are increasingly used in the wind turbine manufacture industry as flow control devices to improve rotor blade aerodynamic performance. Nevertheless, VGs may produce excess residual drag in some ...
