Journal ArticleDOI
Functionalized Single Graphene Sheets Derived from Splitting Graphite Oxide
Hannes C. Schniepp,Je-Luen Li,Michael J. McAllister,Hiroaki Sai,Margarita Herrera-Alonso,Douglas H. Adamson,Robert K. Prud'homme,Roberto Car,Dudley A. Saville,Ilhan A. Aksay +9 more
TL;DR: The process yields a wrinkled sheet structure resulting from reaction sites involved in oxidation and reduction processes, and functionalized graphene produced by this method is electrically conducting.
(CdSe)ZnS Core−Shell Quantum Dots: Synthesis and Characterization of a Size Series of Highly Luminescent Nanocrystallites

Journal ArticleDOI
Crystallization Kinetics of Organic–Inorganic Trihalide Perovskites and the Role of the Lead Anion in Crystal Growth
David T. Moore,Hiroaki Sai,Kwan Wee Tan,Detlef-M. Smilgies,Wei Zhang,Henry J. Snaith,Ulrich Wiesner,Lara A. Estroff +7 more
TL;DR: In situ X-ray scattering data is used to study isothermal transformations of perovskite films derived from chloride, iodide, nitrate, and acetate lead salts and suggests that careful choice of the lead salt will aid in controlling crystal growth, leading to superior films and better performing solar cells.
Journal ArticleDOI
Thermally induced structural evolution and performance of mesoporous block copolymer-directed alumina perovskite solar cells.
Kwan Wee Tan,David T. Moore,Michael Saliba,Hiroaki Sai,Lara A. Estroff,Tobias Hanrath,Henry J. Snaith,Ulrich Wiesner +7 more
TL;DR: In situ grazing incidence wide-angle X-ray scattering and scanning electron microscopy are utilized to investigate the structural evolution and film morphologies of methylammonium lead tri-iodide/chloride in mesoporous block copolymer derived alumina superstructures during thermal annealing, demonstrating how understanding the processing parameters provides the foundation for optimal perovskite film morphology and coverage.
Journal ArticleDOI
Hierarchical Porous Polymer Scaffolds from Block Copolymers
Hiroaki Sai,Kwan Wee Tan,Kahyun Hur,Emily Asenath-Smith,Robert Hovden,Yi Jiang,Mark L. Riccio,David A. Muller,Veit Elser,Lara A. Estroff,Sol M. Gruner,Ulrich Wiesner +11 more
TL;DR: A synthesis method combining well-established concepts of macroscale spinodal decomposition and nanoscale block copolymer self-assembly with porosity formation on both length scales via rinsing with protic solvents is introduced.
