Improving Plasma‐Catalytic Ammonia Synthesis Using a Coaxial Double‐Helix‐Electrode Reactor

open access: yesChemSusChem, Volume 19, Issue 7, 14 April 2026.
A symmetric double‐dielectric, double‐helix dielectric barrier discharge (DBD) reactor enables uniform volume discharge, enhanced energetic electrons, and strong plasma‐catalyst synergy, delivering high‐efficiency ammonia synthesis under mild, low‐carbon conditions.

Damping Modification Factors for Pile–Induced Filtering Effect

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 4, Page 907-925, 10 April 2026.
ABSTRACT Period–dependent Damping Modification Factors are usually applied to the 5%–damped pseudo–acceleration response spectrum at free field conditions to derive the seismic demand for structures with damping ratio other than 5%. Likewise, the response spectrum at the foundation level of pile–supported structures may differ from the free field ...

Seismic Design of Concrete Dams: An Integrated Risk‐Informed Performance‐Based (RIPB) Framework

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 5, Page 1019-1049, 25 April 2026.
ABSTRACT This paper advances the integration of risk‐informed principles into the seismic design of dams—a domain long guided by standards‐based, largely deterministic approaches. While performance‐based earthquake engineering is well established for buildings and bridges, its systematic adoption in dam engineering remains limited. We first address two

Construction and Damage Analysis of a Three‐Factor Collision Model for Potato‐Soil‐Pole

open access: yesFood Science &Nutrition, Volume 14, Issue 4, April 2026.
In this study, the potato‐soil‐pole three‐factor collision model was constructed with the potato‐soil ratio, impact velocity and impact object as the core factors, and a new coupled pole was designed to alleviate the impact damage. The potato‐soil finite element model was constructed by reverse engineering, and the deviation of the traditional ...

Grain Boundary Fracture of a Magnesium Aluminate Spinel Bi‐Crystal: Microscale Experiments With Varying Mode Mixity

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 4, April 2026.
ABSTRACT In this work, failure of a magnesium aluminate spinel (MgAl2O4) is investigated at the microscale by concurrent in situ imaging and loading within a transmission electron microscope. The goal of the effort is to quantitively measure the grain boundary fracture toughness of a spinel bi‐crystal and study the toughness property disparity between ...
