Poisoning Mechanism Map for Metal Hydride Hydrogen Storage Materials

Advanced Science, Volume 11, Issue 43, November 20, 2024.
The poisoning mechanisms of impurity gases on hydrogen storage materials are classified into two basic categories. During hydrogenation, inactive gases cause a minimal blanket effect by physically obstructing H2 diffusion in H2‐impurity mixed gas, while active gases significantly poison materials by chemically limiting H2 absoprtion at interface.

Sensitivity of seismically cued antineutrino detectors to nuclear explosions

, 2018
We evaluate the sensitivity of large, gadolinium-doped water detectors to antineutrinos released by nuclear fission explosions, using updated signal and background models and taking advantage of the capacity for seismic observations to provide an ...

Limitations of Hydrogen Detection After 150 Years of Research on Hydrogen Embrittlement

Advanced Engineering Materials, Volume 26, Issue 19, October 2024.
This article reviews the phenomenon of hydrogen embrittlement in metallurgy, tracing its historical origins and examining experimental limitations in detecting hydrogen at nanoatomic scales. It evaluates theoretical models and proposes that further development of experimental science is needed to either validate or disprove current HE theories ...

An experimental comparison of contributions in collective prevention games and public goods games

Economic Inquiry, Volume 62, Issue 4, Page 1598-1617, October 2024.
Abstract In many collective action problems individuals' contributions increase the probability of a collectively favorable event rather than affect the quantity of public goods provided. Such problems, that we refer to as collective prevention games, remain largely unexplored in the literature.

Comparative evaluation of solar, fission, fusion, and fossil energy resources, part 3 [PDF]

The role of nuclear fission reactors in becoming an important power source in the world is discussed. The supply of fissile nuclear fuel will be severely depleted by the year 2000. With breeder reactors the world supply of uranium could last thousands of

Monitoring of Allowable Bending Stress Overload in Glass‐Fiber‐Reinforced Polymer Composites Using Magnetostrictive Fe–Co Fibers

Advanced Engineering Materials, Volume 26, Issue 4, February 2024.
This article discusses the magnetostrictive behavior of Fe–Co fibers in glass‐fiber‐reinforced‐polymer (Fe–Co fiber/GFRP) composites. The magnetic flux density outside the Fe–Co fiber/GFRP composite specimens is monitored during the four‐point bending tests.

Rapid chemical separations for thermal neutron activation analysis of niobium and vanadium and application to controlled thermonuclear reactor materials studies

Journal of Radioanalytical Chemistry, 1977
Procedures are described for rapid, high yield chemical separation of niobium and vanadium from surfaces of quartz, silicon, and carbon following thermal neutron activation. Practical detection limits for stable niobium and vanadium are 7·1010 and 6·1011 atoms respectively.
