Mineralogy and Petrology of an Olivine Diabase Sill Complex and Associated Unusually Potassic Granophyres, Sierra Ancha, Central Arizona [PDF]

open access: yes, 1969
The Precambrian Sierra Ancha sill complex, 700 to 800 feet thick, was intruded into flat-lying sedimentary rocks of the Apache Group in central Arizona. The bulk of the complex consists of a central layer of feldspathic olivine-rich diabase and upper and

Considerations for Discrete Element Modeling of Rock Cutting [PDF]

open access: yes, 2013
This study attempts to build a framework within the Discrete Element Method (DEM) to produce a reliable predictive tool in rock cutting applications, such that the cutting forces and fragmentation process are reasonably estimated. The study is limited to

Electrospun Wood‐Derived Biopolymers as Electrodes in Electrochemical Energy Storage Technologies

open access: yesAdvanced Functional Materials, EarlyView.
Electrospinning transforms wood‐derived cellulose and lignin into architecturally defined, binder‐free carbon electrodes with tuneable porosity and functionality. This review shows how fibre design enables decoupled charge and mass transport, enhancing performance across battery systems, while identifying key challenges in spinnability, scalability ...
