TL;DR: Energy-rich polyethylene (PE) macromolecules are catalytically transformed into value-added products by hydrogenolysis using well-dispersed Pt nanoparticles (NPs) supported on SrTiO3 perovskite nanocuboids by atomic layer deposition.
Journal ArticleDOI

TL;DR: In this paper, a Pt/SiO2 catalyst is used for the selective hydrogenolysis of high-density polyethylene into narrow alkane fractions, which is based on a mesoporous silica shell.
Journal ArticleDOI
Dynamic Nuclear Polarization Solid-State NMR in Heterogeneous Catalysis Research
TL;DR: In this paper, a revolution in solid-state nuclear magnetic resonance (SSNMR) spectroscopy is taking place, attributable to the rapid development of high-field dynamic nuclear polarization (DNP), a technique yielding sensitivity improvements of 2-3 orders of magnitude.
Journal ArticleDOI
Natural Abundance 17O DNP Two-Dimensional and Surface-Enhanced NMR Spectroscopy
TL;DR: New DNP-based measurements that extend (17)O solid-state NMR beyond its current capabilities are demonstrated and the detection of surface hydroxyl sites on mesoporous silica at natural abundance is enabled, for the first time, thereby extending the concept of DNP surface-enhanced NMR spectroscopy to the ( 17)O nuclide.
Journal ArticleDOI
Potent inhibition of ice recrystallization by low molecular weight carbohydrate-based surfactants and hydrogelators
Chantelle J. Capicciotti,Mathieu Leclère,Frédéric A. Perras,David L. Bryce,Hilary Paulin,James L. Harden,Yun Liu,Robert N. Ben +7 more
TL;DR: This paper describes the first example of low molecular weight carbohydrate-based derivatives that exhibit potent IRI activity and demonstrates that carbohydrate hydration is important for Iri activity and that the formation of micelles in solution is not a prerequisite for IRIactivity.
