Pressurized plankton observatory offers a new window into deep‐sea larval behavior

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract The High‐Pressure Plankton Observatory (HiPPO) is designed to quantify motions of zooplankton for behavioral study, including swimming and metabolic responses to environmental perturbations. It builds on prior chamber designs while filling gaps in capability for resolving orientation of small (< 1 mm) plankton, tracking their movements over ...

The Influence of Subcritical Annealing and Cold Working on the Hydrogen Embrittlement Susceptibility of X65 D Pipeline Steel

open access: yesMaterials and Corrosion, EarlyView.
This study investigated the effect of subcritical heat treatment and cold work on the hydrogen embrittlement (HE) susceptibility of the X65 D pipeline steel. Hydrogen charging reduced the ductility of all specimens. Both subcritical annealing and cold working decreased somewhat the degree of HE.

Stress Corrosion Tests for Prestressing Steels—Part 2: Susceptibility of Quenched and Tempered Wires—Influence of Chromium

open access: yesMaterials and Corrosion, EarlyView.
Cr‐alloyed quenched and tempered prestressing steel wires were found to be as highly susceptible as non‐Cr‐alloyed ones. This finding is in contrast to the known literature. A newly developed and reproducible method for assessing susceptibility to hydrogen‐induced stress corrosion cracking was used.
