Investigation of a ceramic metal matrix composite functional surface layer manufactured using gas tungsten arc welding [PDF]

open access: yes, 2014
Wear resistant surfaces with high toughness and impact resistant properties are to be created to improve the life cycle cost of brake discs for trains. A potential solution to this industrial problem is to use an arc cladding process.

Mineralogical and Chemical Analysis of Fracture and Matrix Minerals in Selected Samples of the Culebra Dolomite

open access: yes, 2001
Contaminant release scenarios proposed for the Waste Isolation Pilot Plant (WIPP) repository suggest that the Culebra Dolomite member of the Rustler Formation could be an important radionuclide release path. This thin, vuggy, highly fractured unit is the most transmissive geologic unit overlying the WIPP.

Classification of sheep category using chemical analysis and statistical classification algorithms

open access: yes, 2011
In Australia, dentition (eruption of permanent incisors) is used as a proxy for age to define sheep meat quality. Lamb is defined as having no permanent incisors, hogget as having at least one incisor and mutton is defined as having two or more incisors.

Investigation of fiber/matrix adhesion: test speed and specimen shape effects in the cylinder test

open access: yes, 2013
The cylinder test, developed from the microdroplet test, was adapted to assess the interfacial adhesion strength between fiber and matrix. The sensitivity of cylinder test to pull-out speed and specimen geometry was measured.

Shape Memory Actuator: thermomechanical training and surface optimization of shape memory wires embedded in a polymeric matrix

open access: yes, 2011
In the first part of my work I studied the mechanical and thermal behaviour of NiTi wires and strips in order to find the best training cycle to achieve a good compromise between transformation temperatures, recovery forces and phase reversibility ...

Flavonoid mixture analysis by matrix-assisted diffusion-ordered spectroscopy

open access: yes, 2012
The structural similarity of flavonoids, often present in natural product mixtures, makes their analysis by NMR methods less than straightforward. This similarity is a dual problem for one of the most powerful NMR methods for mixture analysis, diffusion ...

Monitoring and simulations of hydrolysis in epoxy matrix composites during hygrothermal aging [PDF]

open access: yes, 2014
In this paper, we studied the water transport in thermoset matrices. We used Fourier Transform Infrared analysis (FTIR) during sorption/desorption experiments to investigate the interaction between sorbed water and the epoxy network.

Influence of the Physico-chemical Characteristics of the Hybrid Matrix on the Catalytic Properties of Sol-gel Entrapped Pseudomonas fluorescens Lipase

open access: yes, 2016
Lipase from Pseudomonas fluorescens (Amano AK) was immobilized using the sol-gel entrapment technique and sol-gel entrapment combined with adsorption on a solid support (Celite 545). The sol-gel matrices were obtained using as precursors ternary mixtures

Effective theories of finite volume QCD

open access: yes, 2008
Finite volume QCD close to the chiral limit cannot be described by chiral Perturbation Theory using the usual p-expansion when the correlation length of pions becomes larger than the size of the box.

Chemical fixation of electroplating sludge and microstructural analysis of stabilised matrix using fly ash and cement

open access: yesMaterials Research Innovations, 2009
AbstractStabilisation and microstructural examination of stabilised electroplating industrial sludge has been studied. Investigations were undertaken to formulate cementitous binder by judicious blending of fly ash, sludge and cement with five mix proportions. The major metallic contaminants were cadmium, chromium, copper, nickel and lead.
