Numerical and analytical modeling of annular flow reveals the hydraulic performance of sustainable drilling muds formulated from Congolese kaolinitic clay, okra mucilage, and plant ashes. Yield stress enhances cuttings transport, while shear‐thinning behavior reduces pressure losses and pumping energy.

ABSTRACT Infected bone defects represent a dual therapeutic challenge demanding concurrent infection inhibition and osteogenesis promotion. Systemic antibiotic administration is taken as a classical treatment protocol but often yields inadequate local antibiotic concentrations and delayed bone repair.

Exhumed eo‐Alpine High‐Pressure Rocks Fed Campanian Turbidites in Eastern Sardinia
Abstract This study investigates the detrital record of the early orogenic evolution of the Sardinia‐Calabria system, preserved in Upper Cretaceous arenites exposed in eastern Sardinia. Sardinia and Corsica form a continental block that includes a segment of the Alpine orogen and of its former foreland basin.

Abstract Accurate interpretation of time‐variable gravity from GRACE (‐FO) requires correction for glacial isostatic adjustment (GIA), which has a gravitational signal similar in magnitude to that of contemporary hydrological and cryospheric mass change.

Textured Piezoelectric Ceramics Printed With Baffled Nozzles
To better align platelet particles in additively manufactured textured ceramics, baffled nozzles were simulated and tested. The simulation included a novel CFD heuristic that considers the entire print path. Printed parts were characterized via microscopy, X‐ray diffraction, and electromechanically and results were compared to the simulation, finding ...
