Channel cut polishing machine

A device for polishing of a multi-surface workpiece is described. The device includes a base and a vertical motion platform that moves along two support rods, which carries a motor that drives a rotating shaft. The support rods extend from the base. A polishing tool is attached to the motor shaft. The workpiece being polished is placed on a linear motion stage during the polishing process.

Building a Cutting-Edge STEM to Study Nuclear Materials

The Radiochemical Processing Laboratory at PNNL is home to a new flagship JEOL GrandARM-300F scanning transmission electron microscope. This unique instrument will allow unprecedented atomic-scale characterization of nuclear materials, structural alloys, and functional systems in dynamic conditions.

Cutting-Edge Operations Concepts: Intelligent Infrastructure, Cooperative Driving, Signal Control, and Curbside Management

The objective of this breakout session at the NREL Mobility workshop was to examine emerging traffic operations concepts built on key detection technology such as radars, lidars, and imaging recognition - and identify challenges and paths forward to integrate into our current roadway system. The key objective were to identify the opportunities for intelligent infrastructure to support near-term safety, equity, energy, and congestion mitigation goals, while supporting longer term connected-automated vehicle objectives. In the plenary session, Eric Raamot, from the USDOT Highly Automated Safety Systems Office challenged the participants to think broadly about the roll of standards and reference architecture to provide both an accelerated rollout of intelligent infrastructure, but also a repeatable and supportable framework upon which many infrastructure owners and operators (IOOs) could utilize for their implementation purposes.
