Journal ArticleDOI
Tuning clathrate hydrates for hydrogen storage
Huen Lee,Jongwon Lee,Do Youn Kim,Jeasung Park,Yutaek Seo,Huang Zeng,Igor L. Moudrakovski,Christopher I. Ratcliffe,John A. Ripmeester +8 more
TL;DR: Hydrogen storage capacities in THF-containing binary-clathrate hydrates can be increased to ∼4 wt% at modest pressures by tuning their composition to allow the hydrogen guests to enter both the larger and the smaller cages, while retaining low-pressure stability.
Journal ArticleDOI
Giant nonlinear response from plasmonic metasurfaces coupled to intersubband transitions
Jongwon Lee,Mykhailo Tymchenko,Christos Argyropoulos,Pai-Yen Chen,Feng Lu,Frederic Demmerle,Gerhard Boehm,Markus-Christian Amann,Andrea Alù,Mikhail A. Belkin +9 more
TL;DR: The proposed structures can act as ultrathin highly nonlinear optical elements that enable efficient frequency mixing with relaxed phase-matching conditions, ideal for realizing broadband frequency up- and down-conversions, phase conjugation and all-optical control and tunability over a surface.
Journal ArticleDOI
Sequestering carbon dioxide into complex structures of naturally occurring gas hydrates
TL;DR: The swapping phenomenon occurring in structure I (sI) and structure II (sII) CH4 hydrate deposits is explored through spectroscopic analyses and its potential application to CO2 sequestration at the preliminary phase is explored.
Journal ArticleDOI
Efficient recovery of CO2 from flue gas by clathrate hydrate formation in porous silica gels.
TL;DR: Thermodynamic measurements and NMR spectroscopic analysis were used to show that it is possible to recover CO2 from flue gas by forming a mixed hydrate that removes CO2 preferentially from CO2/N2 gas mixtures using water dispersed in the pores of silica gel.
Journal ArticleDOI
Gradient Nonlinear Pancharatnam-Berry Metasurfaces
Mykhailo Tymchenko,J. Sebastian Gomez-Diaz,Jongwon Lee,Nishant Nookala,Mikhail A. Belkin,Andrea Alù +5 more
TL;DR: This work applies the Pancharatnam-Berry phase approach to plasmonic metasurfaces loaded by highly nonlinear multiquantum-well substrates, establishing a platform to control the nonlinear wave front at will based on giant localized nonlinear effects.
