This study investigates the impact of calcium on the performance of a large‐scale internal circulation (IC) reactor treating calcium‐rich dairy wastewater. Excessive calcium concentrations (400‐600 mg L−1) resulted in calcification of the anaerobic sludge, reactor walls, and pipes, suggesting a 17% and 25% reduction in biogas and methane production ...

Abstract Barite serves as a key proxy for reconstructing paleo‐oceanic productivity and chemistry in modern and ancient marine sediments. Although contemporary barite precipitation involves biological mediation, the mechanisms responsible for ancient barite formation remain unclear.

Abstract S, Tl, and W isotope records document pronounced early Eocene shifts in marine redox, yet the absence of a Mo isotope record obscures its progression. Here, we present ∼80 Myr Mo–Os–Be–Nd isotope profiles from a Northwest Pacific hydrogenetic Fe–Mn crust, revealing a systematic δ98Mo decline from −0.24‰ (early Eocene) to −0.83‰ (early ...

Fluorination of Silver Phosphate in Nickel Reaction Vessels for Triple Oxygen Isotope Analysis
ABSTRACT Rationale Increasingly, more laboratories are measuring the triple oxygen isotope values of phosphate. Standardization is key to having good interlaboratory results. Here, we present the triple oxygen isotope values of a suite of standards using fluorination and compare them with previously reported triple oxygen isotope values. Methods Silver
