Roughness Measurements at Small and Uneven Surfaces of Ceramic Foam Filters

open access: yesSurface and Interface Analysis, Volume 58, Issue 7, Page 471-490, July 2026.
ABSTRACT This study investigated the possibility of roughness characterization of ceramic foam filters using a laser scanning microscope, examining the influence of magnification, measured area, cutoff wavelength (λc), measured roughness parameter, and position within the ceramic foam on the measured roughness data. Firstly, the effect of magnification

Defining the geographical level of competition: a taxonomy of industry tradability

open access: yesEconomica, Volume 93, Issue 371, Page 962-991, July 2026.
Abstract The paper develops a taxonomy of industry tradability to define the geographical level at which competition takes place. First, it creates a novel dataset that combines production and international trade data for both goods and services industries, defined at a detailed (3‐digit) level of industry aggregation for 15 European countries.

On the Conservatisms of Nepheline Predictors for Canister Centerline Cooled (CCC) High‐Level Waste (HLW) Glasses

open access: yesInternational Journal of Applied Glass Science, Volume 17, Issue 3, July 2026.
ABSTRACT Multiple models and feature sets have been generated, which attempt to predict the crystallization of nepheline (NaAlSiO4) in high‐level radioactive waste (HLW) glasses under canister centerline cooling (CCC) conditions. Earlier models were found to be overly conservative, while newer models had a not insignificant rate of false positives and ...
