Fluid Injection Triggers Large‐Scale Slow‐Slip Activation of the Rocky Mountain Fold and Thrust Belt
Abstract Using interferometric synthetic aperture radar (InSAR) we show that hydraulic fracturing treatments near the subsurface deformation limit of the Rocky Mountain Fold and Thrust Belt produced 12 intraplate, aseismic, slow‐slip events with magnitudes Mw ${M}_{w}$ 4.71–5.06 at 1,640–2,410 m depths.

Synthesis of functionalized polyolefins in a new continuous bench‐scale reactor apparatus
Abstract In‐reactor functionalized polyolefins (FPOs), produced by molecular catalysts, are a new class of polymer materials with applications ranging from high performance adhesives to bitumen compatibilization. In this work, we disclose a procedure for the synthesis of FPOs in a new Continuous Bench‐scale Reactor Apparatus (COBRA).

How life affects mineral formation: A reappraisal of concepts and terminology
We present a moderately revised terminology of concepts how life may influence mineral formation. This framework would be more consistent and universally applicable. Abstract Numerous biological factors have been proposed to influence the formation of minerals under Earth‐surface conditions, but the underlying concepts are often confused due to ...
