Zn/Al‐NO3 Layered Double Hydroxide as Alternative Activator for Nitrile Rubber Vulcanization: Effect of the Accelerator‐to‐Sulfur Ratio on Curing Kinetics and Network Properties

open access: yesJournal of Applied Polymer Science, EarlyView.
Zn/Al‐NO3 layered double hydroxide offers a low‐zinc alternative for sulfur vulcanization of nitrile rubber, reducing nominal zinc loading by an estimated 71%. Its potential as a vulcanization activator depends on the curing system: conventional curing preserves tensile strength despite slower kinetics, whereas efficient curing maintains comparable ...

Redescription of †Eobrasilia coutoi (Metatheria: Polydolopimorphia), a unique sclerocarpophagous metatherian from the Palaeogene of South America: Systematic affinities, and paleoecological and evolutionary implications

open access: yesThe Anatomical Record, EarlyView.
Abstract The ‘Palaeogene strata’ of the Itaboraí Basin (upper Paleocene‐lower Eocene), Southeastern Brazil, has preserved 29 genera and almost 50 species of metatherians (about 65% of its mammalian diversity). Among them, Eobrasilia coutoi Simpson, 1947 is the most enigmatic due to its quite fragmentary nature.

Deciphering the Palimpsest: Chronological Uncertainty and the Interpretation of Mining Landscapes at Písečný vrch (Czech Republic)

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT We investigated the Písečný vrch (Czech Republic), a site exploited for quartz mining in both prehistoric times and the 20th century. Due to their morphological similarity across all mining periods, the differentiation between pits with archaeological potential and recent ones is challenging.

Modeling Acoustic Attenuation, Sound Velocity and Wave Propagation in Lithium‐Ion Batteries via a Transfer Matrix

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
“A simple 1D transfer matrix model of a battery is introduced and parametrized using harvested individual cell components at 0 % and 100 % SoC. This model allows for the calculation of group velocity and attenuation. The results of the model show good agreement with measured values, highlighting increased attenuation and group velocity at the ...

Expanding Metabolic Online Monitoring Capabilities in 96‐Deepwell Microtiter Plates by Combining Optoelectronic O2 and CO2 Sensors

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT To increase the information content in early stages of bioprocess development, various technologies have been introduced for monitoring cultivations in microtiter plates (MTPs). Besides spectroscopical measurements, like in the BioLector technology, optical measurements with luminescent sensors, placed directly in the cultivation medium ...
