Experimental investigation of an aggregate material behavior under confinement at high strain rate
EPJ Web of Conferences, 2010 Low velocity impacts can ignite explosives or energetic materials. Ignition depends on the mechanical behavior of the energetic material which needs to be characterized for both high pressure level and high strain rate.

Role of extracellular carbonic anhydrase in the polar diatom Fragilariopsis cylindrus
New Phytologist, EarlyView.Summary Diatoms are major primary producers in productive polar oceans, where cold temperatures and high CO2 solubility raise questions as to whether they rely on the CO2‐concentrating mechanism (CCM) to saturate photosynthesis. Knowledge of CCM function will help better predict the sensitivity of diatom primary production to warming and acidifying ...

A Constant Acoustic Impedance Mount for Sheet-Type Specimens in the Tensile Split-Hopkinson Bar
EPJ Web of Conferences, 2018 This paper addresses a problem well-known amongst practitioners of the Split-Hopkinson Tension Bar method: attaching a flat test specimen made from sheet material to the cylindrical input-and output bars.

Photosynthetic primary production in the Mesoproterozoic
New Phytologist, EarlyView.Summary The Mesoproterozoic atmosphere had more CO2 and less O2 than at present. While the upper ocean was oxygenated, the deeper ocean was euxinic or ferruginous. Primary production was performed by Chlorobia, Cyanobacteria, Proteobacteria, and Archaeplastida.

Pandemic Geographies of Home: Domestic Thresholding in Response to COVID‐19
Transactions of the Institute of British Geographers, EarlyView.Short Abstract With the home at the forefront of political and public health responses to COVID‐19, the thresholds between domestic space and the world beyond acquired a new significance in people's everyday lives. This paper introduces the concept of ‘thresholding’ to explore the ways in which internal and external thresholds are understood and ...

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.ABSTRACT Triply periodic minimal surfaces (TPMS) constitute a prominent class of cellular structures and have gained considerable attention in current research. These structures are genus‐infinite surfaces with zero mean curvature, which prevents self‐intersection. They also exhibit periodicity in all three spatial directions and exhibit enhanced multi‐

Microbial Controls on Dissolved Organic Nitrogen Cycling During Long‐Term Degradation Experiments
Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.Abstract Dissolved organic nitrogen (DON) is critical for marine microbial growth by providing carbon and nitrogen. Although DON is rapidly cycled, some compounds within this pool can persist for long‐periods of time. To better understand how DON is cycled by marine microorganisms, we conducted 548‐day incubations using surface‐derived dissolved ...

On loading velocity oscillations during dynamic tensile testing with flying wheel systems
EPJ Web of Conferences, 2015 Flying Wheels (FW) provide a space-saving alternative to Split Hopkinson Bar (SHB) systems for generating the loading pulse for intermediate and high strain rate material testing.
