Role of C–N configurations in the photoluminescence of graphene quantum dots synthesized by a hydrothermal route

Publication

Scientific Reports

Permatasari, F. A.; Aimon, A. H.; Iskandar, F.; Ogi, T.; Okuyama, K.

Graphene quantum dots (GQDs) containing N atoms were successfully synthesized using a facile, inexpensive, and environmentally friendly hydrothermal reaction of urea and citric acid, and the effect of the GQDs’ C–N configurations on their photoluminescence (PL) properties were investigated.
Alkoxide-intercalated NiFe-layered double hydroxides magnetic nanosheets as efficient water oxidation electrocatalysts

Inorganic Chemistry

Carrasco, J. A.; Romero, J.; Varela, M.; Hauke, F.; Abellán, G.; Hirsch, A.; Coronado, E.

Alkoxide-intercalated NiFe-layered double hydroxides were synthesized via the nonaqueous methanolic route. These nanoplatelets exhibit high crystalline quality as demonstrated by atomic resolution scanning transmission electron microscopy combined with electron energy-loss spectroscopy.

Gilks, D.; Nedelkoski, Z.; Lari, L.; Kuerbanjiang, B.; Matsuzaki, K.; Susaki, T.; Kepaptsoglou, D.; Ramasse, Q.; Evans, R.; McKenna, K.; Lazarov, V. K.

We report the existence of a stable twin defect in Fe3O4 thin films. By using aberration corrected scanning transmission electron microscopy and spectroscopy the atomic structure of the twin boundary has been determined.
Fundamentals of electron energy-loss spectroscopy

Publication

EMAS 2015 Workshop

Hofer, F.; Schmidt, F. P.; Grogger W.; Kothleitner, G.

Electron energy-loss spectroscopy (EELS) is an analytical technique that is based on inelastic scattering of fast electrons in a thin specimen. In a transmission electron microscope (TEM) it can provide structural and chemical information about a specimen, even down to atomic resolution.
Heterogeneous diamond phases in compressed graphite studied by electron energy-loss spectroscopy

Publication

Diamond and Related Materials

Sato, Y.; Bugnet, M.; Terauchi, M.; Botton, G. A.; Yoshiasa, A.

Chemical mapping imaged by electron energy-loss spectroscopy based on scanning transmission electron microscopy was conducted on a compressed graphite specimen containing different carbon allotropes (hexagonal diamond, cubic diamond, and graphite phases).

EMAS 2015 Workshop

Gaslain, F. O. M.; Le, H. T.; Duhamel, C.; Guerre, C.; Laghoutaris, P.

Alloy 600 is used in pressurized water reactors (PWRs) but is susceptible to primary water stress corrosion cracking (PWSCC). Intergranular chromium carbides have been found beneficial to reduce PWSCC.
