Automated mineralogy (SEM-EDS) approach to sandstone reservoir quality and diagenesis
Porosity and permeability define the reservoir quality of a sandstone. Porosity and permeability are controlled by primary sedimentary characteristics and subsequent diagenetic modification.

Electrochemical extraction of europium from molten fluoride media [PDF]
This work concerns the extraction of europium from molten fluoride media. Two electrochemical ways have been examined: (i) the use of a reactive cathode made of copper and (ii) the co-deposition with aluminium on inert electrode, leading to the formation

Automated Gunshot Analysis by SEM/EDS [PDF]
Abstract Firearms are involved in roughly 60% of all murders, 33% of all robberies and almost 25% of aggravated assaults. Given these statistics, it is easy to see why a determination of whether an individual has recently been in the immediate vicinity of a discharged firearm is important to law enforcement.

Corrosion behaviour of nitrided ferritic stainless steels for use in solid oxide fuel cell devices
Plasma nitriding was applied to ferritic stainless steel substrates to improve their performances as interconnects for solid oxide fuel cell devices. The samples underwent electrical conductivity test and SEM/EDS, TEM/EDS, environmental-SEM analyses. The
