Several UK CAER colleagues received funding on three of 10 U.S. Department of Energy’s (DOE) National Energy Technology Laboratory (NETL) projects. NETL funded this series of projects as part of their Recovery of Rare Earth Elements from Coal and Coal Byproducts program. The selected research projects will further program goals by focusing on the development of cost-effective and environmentally benign approaches for the recovery of rare earth elements (REEs) from domestic coal and coal byproducts.

UK CAER Team Publishes in the ACS Journal Chemistry of Materials

John Anthony and Chad Risko have joined forces in a recent publication in the ACS Journal Chemistry of Materials titled "Dynamics, Miscibility, and Morphology in Polymer:Molecule Blends: The Impact of Chemical Functionality.” Drs. Anthony and Risko are based in Lab 2 at UK CAER and also hold faculty appointments in the UK College of Arts & Sciences Department of Chemistry.

Based on a series of acceptors constructed from trialkylsilylethynyl-substituted pentacenes designed and synthesized in the Anthony laboratory, the study presents a computational chemistry investigation of polymer:molecule blends with the polymer donor poly(3-hexylthiophene) (P3HT). Essential connections are made between the chemical structure of the acene acceptor and the nanoscale properties of the polymer:molecule blend, which include polymer and molecular diffusivity, donor–acceptor packing and interfacial (contact) area, and miscibility. The results point to the very significant role that seemingly modest changes in chemical structure play during the formation of polymer:molecule blend morphologies, and how molecule design can be used to control critical aspects of thin-film morphology.

Podcast of CAER Seminar Speaker - Professor Bittnar

The University of Kentucky's Center for Applied Energy Research has published another podcast for individuals interested in energy issues.

It explored the topic of Validation of Multiscale Model for Heat Generation in Hardening Concreteby Professor Bittnar, Civil Engineering, Fellow of the Engineering Academy - Czech Technical University.

- Podcast and PPT File

Temperature rise in hydrating concrete presents a formidable problem that may lead to significant acceleration of hydration kinetics, early-age cracking, and decreased durability. Multiscale formulation was developed, coupling a cement hydration model on the microscale with the finite element method (FEM) solving heat conduction problem on the macroscale. Although discrete hydration model predicts heat evolution controlled by macroscale temperature, the FEM satisfies heat balance equation during thermal conduction. 2D validations show reasonable temperature agreement with an access to the local quantities, such as a degree of hydration. Here, this multiscale and coupled model is validated against two in situ bridge constructions.



UK CAER Makes Splash at UK Sustainability Forum

The University of Kentucky Center for Applied Energy Research (CAER) made quite the splash at the 2015 University of Kentucky Sustainability Forum and Research Showcase Tuesday. Two members of the CAER presented posters during the showcase, and two of the seven UK Sustainability Challenge Grants were awarded to UK CAER projects.

Courtney McKelphin, a undergraduate student researcher at the Center, received Best Poster Award for her project entitled on “Improving the Economics of Algae Biofuels through Optimized Extractions from Wet Algae.”

UK CAER staff member Michael Wilson presented a poster highlighting the engineering achievements in support of the 2014 Challenge Grant Project “Development of Sustainable Bus Stops” along with team members from the College of Design. The project also received 2015 grant funding.

In addition to the poster presentation portion of the event, the President’s Sustainability Advisory Committee awarded nearly $200,000 to campus sustainability projects that focused on the creation and implementation of ideas that promote sustainability by advancing economic vitality, ecological integrity and social equity, now and into the future.

This program is a collaborative effort of the President’s Sustainability Advisory Committee, The Tracy Farmer Institute for Sustainability and the Environment and the Office of Sustainability. Funding for the program was provided by the Executive Vice President for Finance and Administration, the Provost, the Vice President for Research and the Student Sustainability Council.

CAER projects receiving funding included:

Point of Departure - Awarded $49,991

CAER and the College of Design are partnering to construct critically-placed transit shelters—plugging into campus transportation to physically manifest UK’s sustainability and transportation agendas. The designs integrate sustainable site strategies, context specificity, high-performance architectural skins, sustainable materials, photovoltaic systems, storm water management, high-efficiency lighting and infographic displays to reimagine what a shelter can be. This grant will catalyze the integration of sustainability and educational aspects within the design as it transitions toward real world implementation, leveraging the impact of campus research to engage students in a dialogue about sustainability, alternate transportation, the value of design, and the possibilities of collaborative research at UK.

Team Members: Martin Summers, College of Design-School of Architecture; Michael Wilson, CAER; Regina Hannemann, College of Engineering-Electrical Engineering; Owen Duross, College of Design-School of Architecture; Thompson Burry, College of Design-School of Architecture.

From SEE(E)D to (S)STEM - Awarded $25,184

In this project, UK science, engineering, entrepreneurship, education and design – SEE(E)D – students, faculty and staff will work together to develop a system for the production of didactic tools to be used in outreach efforts designed to promote sustainability, science, technology, engineering, and mathematics – (S)STEM – to underserved K-12 students. This will be done utilizing as a case study a game that has been conceived and used to teach K-12 students about complex and often misunderstood energy and sustainability issues. While the science behind this game and the relationship between the latter and the K-12 curriculum are solid, the presentation can be improved to make the game more effective. The game will be improved by having educators and designers strengthen the graphical and pedagogical aspects of the game to ultimately facilitate and deepen the understanding of K-12 students of the important sustainability issues presented. In addition, this effort will be made sustainable from an economic standpoint through a business plan – to be developed by UK student entrepreneurs – in which any profits from the game constituting the case study can be reinvested in the development of additional didactic tools, thus translating this work into a sustainable model through which other tools can be developed. Notably, this work will also serve to advance social equity not only because the K-12 institutions involved have high percentages of minority and/or free and reduced lunch students, but also because minority engineering students will be involved in taking the didactic tool to be developed to these K-12 institutions.

Team Members: Eduardo Santillian-Jimenez, CAER; Rebekah Radtke, College of Design-Department of Interiors; Margaret Mohr-Schoeder, College of Education-Department of STEM Education.

“It was a wonderful forum for showcasing the sustainability efforts at UK, and how our Center is playing a leading role in transforming sustainability education, research and outreach here in Kentucky,” said Courtney Fisk, President’s Sustainability Advisory Committee Co-Chair, and Assistant Director for Facilities and Operations.
