Jet hadronization at LHCb
In high energy proton-proton collisions, collimated sprays of particles,
called jets, result from hard scattered quarks or gluons. Jets are copiously
produced in these collisions; however, the dynamic process through which quarks
and gluons, collectively referred to as partons, become bound state hadrons is
still not well understood. Jets provide an excellent tool to study this process
as they are proxies for the scattered parton; therefore, final-state hadrons
can be measured with respect to an observable that is correlated to the
scattered parton. The LHCb experiment is in an excellent position to measure
hadrons within jets due to its excellent tracking and particle-identification
capabilities. In this talk, new measurements of charged hadrons within jets
measured opposite a boson will be presented from the LHCb collaboration.Comment: on behalf of the LHCb collaboration. Proceedings for the 13th

An organic Rankine receiver for the SCSTPE program
The organic Rankine cycle receiver which is presently being developed is described. The receiver employs an integrated cavity/pool boiler which permits the design of a small, lightweight, low cost and efficient moderate temperature receiver for use in a dish-Rankine solar thermal system
Innovative techniques for the production of energetic radicals for lunar materials processing including photogeneration via concentrated solar energy
The Department of Materials Science and Engineering (MSE) is investigating the use of monatomic chlorine produced in a cold plasma to recover oxygen and metallurgically significant metals from lunar materials. Development of techniques for the production of the chlorine radical (and other energetic radicals for these processes) using local planetary resources is a key step for a successful approach. It was demonstrated terrestrially that the use of UV light to energize the photogeneration of OH radicals from ozone or hydrogen peroxide in aqueous solutions can lead to rapid reaction rates for the breakdown of toxic organic compounds in water. A key question is how to use the expanded solar resource at the lunar surface to generate process-useful radicals. This project is aimed at investigating that question
