Journal ArticleDOI
Polymer Infiltration into Metal–Organic Frameworks in Mixed-Matrix Membranes Detected in Situ by NMR
Pu Duan,Jessica C. Moreton,Sérgio R. Tavares,Rocio Semino,Guillaume Maurin,Seth M. Cohen,Klaus Schmidt-Rohr +6 more
TL;DR: Simulations confirm that PEO penetrates into UiO-66 more easily than does PVDF, and are among the first to provide experimental insights into MOF-polymer interactions in an MMM.
Journal ArticleDOI
Carbon Overcoating of Supported Metal Catalysts for Improved Hydrothermal Stability
Hien N. Pham,Amanda E. Anderson,Robert L. Johnson,Thomas J. Schwartz,Brandon J. O'Neill,Pu Duan,Klaus Schmidt-Rohr,James A. Dumesic,Abhaya K. Datye +8 more
TL;DR: In this article, carbon overcoats are synthesized at mild temperatures, resulting in an open structure, as revealed by 13C NMR, which helps explain why the over-coats do not significantly block the active sites.
Journal ArticleDOI
Carbon Nitride Nanothread Crystals Derived from Pyridine
Xiang Li,Tao Wang,Pu Duan,Maria Baldini,Haw Tyng Huang,Bo Chen,Stephen J. Juhl,Daniel Koeplinger,Vincent H. Crespi,Klaus Schmidt-Rohr,Roald Hoffmann,Nasim Alem,Malcolm Guthrie,Xin Zhang,John V. Badding +14 more
TL;DR: It is shown that pyridine also reacts under compression to form a well-ordered sp3 product: C5NH5 carbon nitride nanothreads, which may improve processability, alters photoluminescence, and is predicted to reduce the bandgap.
Journal ArticleDOI
Composite-pulse and partially dipolar dephased multiCP for improved quantitative solid-state 13 C NMR
Pu Duan,Klaus Schmidt-Rohr +1 more
TL;DR: Improved multiple cross polarization (multiCP) pulse sequences for quickly acquiring quantitative 13C NMR spectra of organic solids are presented and consistently provides performance superior to that of conventional multiCP, without any trade-off.
Journal ArticleDOI
The Chemical Structure of Carbon Nanothreads Analyzed by Advanced Solid-State NMR.
Pu Duan,Xiang Li,Tao Wang,Bo Chen,Stephen J. Juhl,Daniel Koeplinger,Vincent H. Crespi,John V. Badding,Klaus Schmidt-Rohr +8 more
TL;DR: Characterization of the chemical structure of 13C-enriched nanothreads by advanced quantitative, selective, and two-dimensional nuclear magnetic resonance (NMR) experiments complemented by infrared (IR) spectroscopy reveals that almost all carbon atoms are bonded to one hydrogen atom, unlike in amorphous carbon but as is expected for enumerated nanothread structures.
