Multi-criteria analysis of synthesis methods for ni-based catalysts
(Inst Za Kovinske Materiale I In Tehnologie, Ljubjana, 2016)
Catalysts based on the Ni/Al2O3 system are used in a variety of catalytic processes. Catalysts are commonly synthesized through thermochemical routes (impregnation, precipitation, coprecipitation and others). The authors ...
Geopolymerization of low-grade bauxite
(Institute of Metals and Technology, 2014)
In terms of quality, bauxite ore can be classified as high- or low-grade ore. High-grade bauxite ores are used for alumina extraction using the Bayer process, while low-grade bauxite ores have a limited application. In ...
Liquid metal/ceramic interfaces in dental practice and jewellery manufacturing
(Institute of Metals and Technology, 2010)
Metal-ceramic fusing has been the essential step in obtaining materials that benefit from both ceramic and metal constituents. i e where the combined properties of metal and ceramic layers are desirable When considering ...
Nanofoils for soldering and brazing in dental joining practice and jewellery manufacturing
(Institute of Metals and Technology, 2010)
This paper describes the development of novel, reactive Al-Au nano-multilayered foils, their possible application in different fields and a discussion of the nano-foils' suitability for dental and jewellery applications. ...
Mechanical and microstructural properties of the fly-ash-based geopolymer paste and mortar
(Institute of Metals and Technology, 2013)
In this paper we have investigated the influence of synthesis parameters on the mechanical properties of the fly-ash-based geopolymer paste and mortars. Moreover, the influence of an addition of limestone sand on the ...
Synthesis of α-Al2O3 based foams with improved properties as catalyst carriers
(Institute of Metals and Technology, 2014)
This paper explores the possibility of synthesising catalyst supports with improved properties. Alumina foams were produced with the polymer replication technique. Representative high- and low-temperature sintering ceramics ...
Optimization of the recycling processes for magnesium from a highly contaminated waste
(Institute of Metals and Technology, 2014)
With the recently increased use of magnesium alloys, especially in the automotive industry, a large quantity of generated waste, based on magnesium alloys, is expected. Such a waste often contains many impurities such as ...
Friction-stir welding of high-strength aluminium alloys and a numerical simulation of the plunge stage
(Institute of Metals and Technology, 2012)
This paper defines a set of welding parameters for the Friction-Stir Welding (FSW) of two forged panels of the alloy EN AW 7049A in a T652 temper and discusses the plunge stage of FSW using numerical modeling. This ...
Aspects of titanium-implant surface modification at the micro and nano levels
(Institute of Metals and Technology, 2012)
The shape and chemical composition, as well as the macro- and microtopography, of an implant surface have been studied widely as the major factors that positively influence implant osseointegration. Titanium and titanium ...
CFD analysis of exothermic reactions in al-au nano multi-layered foils
(Institute of Metals and Technology, 2011)
This work presents the possibility of numerical modelling using Computational Fluid Dynamics (CFD) in the field of nano-foils. The governing equations were solved using a Finite Volume Methodology (FVM). The computational ...
