Corrosion of Potential Canister Materials During Oxic to Anoxic Transient in Compacted Bentonite

open access: yesMaterials and Corrosion, EarlyView.
A comprehensive analytical approach was applied to investigate material degradation phenomena of cast iron and copper as potential canister materials for the safe disposal of high‐level radioactive waste, as well as compacted bentonite exposed to artificial water relevant for disposal. ABSTRACT The long‐term performance of the engineered barrier system

Improving Human Diving Endurance With a Field‐Deployable Exoskeleton

open access: yesSmartBot, EarlyView.
High energetic demands to overcome drag, combined with a finite supply of self‐contained breathing gas, fundamentally limit human endurance in underwater locomotion. Here, we present DiveMate, a portable exoskeleton that provides adaptive bidirectional assistance synchronized with fin‐kicking during diving, reducing lower‐limb muscle activation and ...

Multi‐Scale Mechanical Behavior of Additive‐Manufactured 316L Stainless Steel Processed by Severe Plastic Deformation

open access: yessteel research international, EarlyView.
The multi‐scale mechanical behavior of additive‐manufactured 316L stainless steel processed by directed energy deposition and high‐pressure torsion is explored. The influence of torsional strain on strength and microstructural evolution is revealed, indicating progressive grain refinement in the ultrafine regime, reaching strength levels nearing 1800 ...

Performance of gas-lubricated cruciform-mounted tilting-pad journal bearings and a damped flexibly mounted spiral-groove thrust bearing [PDF]

open access: yes, 1974
A test program was conducted to determine the performance characteristics of gas-lubricated cruciform-mounted tilting-pad journal bearings and a damped spiral-groove thrust bearing designed for the Brayton cycle rotating unit (BRU).

Gas hydrate growth morphologies and their effect on the stiffness and damping of a hydrate bearing sand

open access: yes, 2008
Using a specially constructed Gas Hydrate Resonant Column (GHRC), the University of Southampton explored different methods of hydrate synthesis and measured the properties of the resulting sediments, such as shear wave velocity (Vs), compressional wave ...

Eco‐ductile design of RC columns: Resolving the conflict between embodied carbon and curvature ductility

open access: yesStructural Concrete, EarlyView.
Abstract Reducing embodied carbon emissions in structural design is of critical importance in combating global climate change. However, the increased material usage and heavy confinement reinforcement required to meet high ductility demands in reinforced concrete columns directly conflict with environmental sustainability goals.

Do Rivals' Trade Secret Protections Affect a Firm's Trade Credit? Evidence From the Inevitable Disclosure Doctrine

open access: yesEuropean Financial Management, EarlyView.
ABSTRACT Using the staggered adoption of the Inevitable Disclosure Doctrine (IDD) across U.S. states, this study examines whether legal protection of trade secrets granted to a firm's rivals affects the firm's trade credit when it is not similarly protected.

Cortical lacunae, not xylem embolism, drive interspecific differences in freeze–thaw hydraulic dysfunction of conifer fine roots

open access: yesNew Phytologist, EarlyView.
Yellow‐cedar has experienced widespread decline as climate change reduces the snowpack that insulates its roots, but the mechanism of injury is unknown. We tested two competing hypotheses in roots of four conifers: loss of xylem conductivity from freeze‐thaw embolism, or loss of radial conductivity from direct freezing injury that forms cortical ...

The Shaft Response Characteristics of Hydrostatic Pocket Journal Gas Bearings with Fluid Damper.

open access: yesJournal of the Japan Society for Precision Engineering, 1992
Pneumatic hammer instability has been the greatest problem in realizing a high stiffness gas bearing with a large pocket in the bearing surface. The authors have already succeeded in realizing a high stiffness and heavy damping hydrostatic thrust gas bearing with a large pocket by the use of fluid damper.
