Effect of surface treatment with biodegradable materials on properties of linerboard made from old corrugated containers (OCC)

TAPPI Journal, 2017
Linerboard produced from old corrugated containers (OCC) shows lower strength properties in comparison with linerboard produced from virgin fibers. This study determined the influence of surface treatment with polyvinyl alcohol (PVOH), ethylene vinyl alcohol (EVOH) (as synthesized biodegradable polymers), chitosan, and anionic starch (as biobased and ...

Structural Control, Evolution, and Accumulation Rates of Massive Sulfides in the TAG Hydrothermal Field

Geochemistry, Geophysics, Geosystems, Volume 21, Issue 9, September 2020., 2020
Abstract The Trans‐Atlantic Geotraverse (TAG) hydrothermal field on the Mid‐Atlantic Ridge is one of the best‐studied hydrothermal systems to date. However, high‐resolution bathymetric data obtained in 2016 by an autonomous underwater vehicle (AUV) reveal new information about the distribution of active and inactive hydrothermal deposits, and their ...

Wide‐Angle Seismic Imaging of Two Modes of Crustal Accretion in Mature Atlantic Ocean Crust

Journal of Geophysical Research: Solid Earth, Volume 125, Issue 6, June 2020., 2020
Abstract We present a high‐resolution 2‐D P‐wave velocity model from a 225‐km‐long active seismic profile, collected over ~60–75 Ma central Atlantic crust. The profile crosses five ridge segments separated by a transform and three nontransform offsets. All ridge discontinuities share similar primary characteristics, independent of the offset.
