Electron work function–a promising guiding parameter for material design
Scientific Reports, 2016 Using nickel added X70 steel as a sample material, we demonstrate that electron work function (EWF), which largely reflects the electron behavior of materials, could be used as a guide parameter for material modification or design.

A Sampling Methodology for INSURV Material Inspections [PDF]
, 2012 Abstract : This technical report summarizes research into sampling methods that the U.S. Navy Board of Inspection and Survey (INSURV) could employ during Material Inspections (MIs) of ships and submarines. The goal is to improve the Board s efficiency in conducting MIs without compromising either Board effectiveness or inspection rigor.

A combined method for DNA analysis and radiocarbon dating from a single sample
Scientific Reports, 2018 Current protocols for ancient DNA and radiocarbon analysis of ancient bones and teeth call for multiple destructive samplings of a given specimen, thereby increasing the extent of undesirable damage to precious archaeological material.

Material Segmentation of Multi-View Satellite Imagery [PDF]
arXiv, 2019 Material recognition methods use image context and local cues for pixel-wise classification. In many cases only a single image is available to make a material prediction. Image sequences, routinely acquired in applications such as mutliview stereo, can provide a sampling of the underlying reflectance functions that reveal pixel-level material ...
