Visible-to-ultraviolet (<340 nm) photon upconversion by triplet-triplet annihilation in solvents
Yoichi Murakami, Ayumu Motooka, Riku Enomoto +3
In this article, visible-to-ultraviolet photon upconversion (UV-UC) by triplet-triplet annihilation in the emission range shorter than 340 nm, which is previously unexplored, is pr…
Integration of Liquid Thermoelectrochemical Conversion into Forced Convection Cooling
Yutaka Ikeda, Kazuki Fukui, Yoichi Murakami
Forced convection cooling is important in numerous technologies ranging from microprocessors in data centers to turbines and engines; active cooling is essential in these situation…
Electroabsorption study of index-defined semiconducting carbon nanotubes
Nicolas Izard, Etienne Gaufrès, Xavier Le Roux +6
Electroabsorption spectroscopy of well-identified index-defined semiconducting carbon nanotubes is reported. The measurement of high definition electroabsorption spectra allows dir…
Photochemical Photon Upconverters with Ionic Liquids
Yoichi Murakami
Photon upconversion based on triplet-triplet annihilation (TTA) of excited triplet molecules is drawing attention due to its applicability for weak incident light, possessing a pot…
Aharonov-Bohm Exciton Absorption Splitting in Chiral Specific Single-Walled Carbon Nanotubes in Magnetic Fields of up to 78 T
Shojiro Takeyama, Hirofumi Suzuki, Hiroyuki Yokoi +2
The Ajiki-Ando (A-A) splitting of single-walled carbon nanotubes(SWNT) originating from the Aharanov-Bohm effect was observed in chiral specific SWNTs by the magneto-absorption mea…
Efficient Photon Upconverters with Ionic Liquids
Yoichi Murakami
This paper presents the development and characterization of photon upconverters fabricated with ionic liquids (ILs), which are novel fluids that are recently drawing attention due…
