SEM/EDS images from a laser printer

open access: yesScanning, 1989
AbstractA method for producing hardcopy images with a laser printer from scanned video images is presented. The advantages and limitations of this method are compared to the traditional Polaroid technique used for scanning electron microscopy and some methods of creating artificial grey scales using arrays of dots are discussed.

Automated mineralogy (SEM-EDS) approach to sandstone reservoir quality and diagenesis

open access: yesFrontiers in Earth Science, 2022
Porosity and permeability define the reservoir quality of a sandstone. Porosity and permeability are controlled by primary sedimentary characteristics and subsequent diagenetic modification.

Tubular microfossils from ∼2.8 to 2.7Ga-old lacustrine deposits of South Africa: A sign for early origin of eukaryotes? [PDF]

open access: yes, 2016
Unequivocal evidence for Archean eukaryotic life has been long sought for and is a matter of lively debate. In the absence of unambiguous fossils this debate has focused on biogeochemical signatures and molecular phylogenies.
