The Clancy Group attends Fall MRS in Boston

The Clancy group had a strong showing at the 2017 Fall Materials Research Symposium (MRS) in Boston, Massachusetts with three group members presenting their research. Henry Herbol led the charge with two posters on his research in Bayesian optimization and hybrid inorganic-organic perovskites, respectively, and a wonderful oral presentation on his work in developing a reactive force field for perovskites. Mardochee Reveil followed up with a very insightful oral presentation on his study of Si diffusion in III-V materials, garnering significant interest from the audience. The conference was capped off with Andrew Ruttinger’s eye-catching poster on the nucleation mechanism of PbS quantum dots in solution. Congratulations to Henry, Mardochee, and Andrew on their successful deliveries at MRS, and we look forward to another good showing at MRS 2018 in Phoenix!

Ace wins the Fall 2017 Hooey Award

Yaset Acevedo (“Ace”) kept up the group’s strong record by winning the department’s Fall 2017 Austin Hooey award for thesis research. This award is the highest honor for research excellence in the Robert F. Smith School of Chemical and Biomolecular Engineering. Ace gave a presentation to about 100 students and faculty in December, highlighting his exciting new work on woven Covalent Organic Framework materials. His research and service accomplishments have also garnered him the Spring 2018 Provost’s Diversity Fellowship award.

Ace wins Outstanding TA Award

Congratulations to “Ace” (Yaset Acevedo) for winning the Outstanding TA in Chemical and Biomolecular Engineering for 2017 – the first time the Clancy group has ever won this distinction, if memory serves. Ace was chosen for his passion for teaching freshmen in the “Intro. to Chemical & Biomolecular Engineering” course and the many times he went “above and beyond” to help students learn the material.

He was also cited for organizing and leading the effort for the CBE WOMEN outreach event to high school girls from rural schools that involved managing over 100 people, and coordinating CBE’s portions of the CURIE and CATALYST Academies for high school youth. To quote from his nomination: “Ace has been instrumental in promoting many students, women and especially the underrepresented, to pursue careers in the STEM fields… Not only is he an outstanding TA, but he is also an outstanding mentor.”

Blaire Sorenson (Clancy group) wins Toni Morrison Graduate Mentoring Award

Blaire Sorenson, an MS/PhD student in the Clancy group studying solution processing of novel solar cell materials, was awarded Cornell’s Toni Morrison Award for Graduate Mentorship. This award recognizes a GSMU Mentor or OADI Graduate Assistant who has made an outstanding contribution to their proteges and OADI and to the university community. “This individual has gone beyond her role to promote diversity, scholarship and professional development. Additionally, she has successfully balanced her own educational goals and desire to help underrepresented students succeed.” OADI is Cornell’s Office of Academic Diversity Initiatives. Nobel Prize-winning author Toni Morrison is a Cornell alumna (MS. ’55).

Tori Sorg Awarded the R.F. Smith School’s Highest Honor for Research Excellence

tori_outreachVictoria (Tori) Sorg received the Austin hooey award for Fall 2016 in recognition of the excellence of her thesis research. Tori gave a departmental seminar on Dec. 5th on her experimental work to increase dopant activation in InGaAs materials. The award also requires a compelling case for the honoree’s service to the department and the community. Tori’s commitment to the CBE Grad Women’s Group and to mentoring a host of students, many of whom have now matriculated to PhD programs across the country, was a key part of her success in securing this prestigious award.

Tori is an NSF Graduate Fellow, and Intel Graduate Fellow. She will graduate in May 2017 and join Intel Corp. where she is surely poised for future success.

Jingyang Wang Passes his Admission to Candidacy Exam

jingyang_mark_wang_new_cropCongratulations to Jingyang for passing his “A” exam this month (Dec. ‘16). Jingyang discussed his ab initio studies of dopant formation energies of Si dopants in InGaAs, including accurate GW calculations of the band gap that were close to experimental values. Jingyang also described his future work on metal/InGaAs interfaces to his committee consisting of Profs. Thompson (MSE), Fennie (AEP) and DiSalvo (Chem.).

Two new Clancy group papers on Lead Halide Perovskite Complexation in Solution

We’ve just published two new papers that offer a novel approach to predict the effectiveness of solubility of lead halide perovskites precursor complexes in solution. The theory behind using the Mayer Bond Order as a metric for predicting the effectiveness of the choice of cations, halides, additives and solvents was just published in Chemistry of Materials. Validating experiments were provided by our Princeton collaborations from Prof. Lynn Loo’s group.

Proof of the practical usefulness of using this metric was shown regarding the promise of THTO as a HOIP additive in a paper published in J. Mater. Chem. A. Check out our inside front cover image!

Former graduate student, Dr. James Stevenson was first author on the Chem. Mater. Paper. Current student, Blaire Sorenson, was the computational lead on the J. Mater. Chem. A paper, which also credited the work of Blaire’s wonderful undergraduate protégée, Angela Harper from Wake Forest University. This work was led by our wonderful U. Va. experimental collaborators in Joshua Choi’s lab.
