Self‐Assembled Cobalt Oxide Nanobeads on the Conducting Van der Waals Semi‐Metal PtTe2 for Catalytic Heterostructure

open access: yesAdvanced Materials Interfaces, EarlyView.
Self‐assembled CoO nanobeads on the Van der Waals surface of PtTe2 were synthesized through simple thermal annealing utilizing the residual oxygen in the annealing chamber. In this study, the electrocatalytic effect for oxygen evolution reaction from CoO nanobeads on conducting PtTe2 was confirmed, elucidating the new pathway to design a ...

Geometry of the Comptonization Region of MAXI J1348−630 through Type-C Quasiperiodic Oscillations with NICER

open access: yesThe Astrophysical Journal
We use the rms and lag spectra of the type-C quasiperiodic oscillation (QPO) to study the properties of the Comptonization region (aka corona) during the low/hard and hard-intermediate states of the main outburst and reflare of MAXI J1348−630.

Spectral Comparisons of Neutron Star Low-Mass X-Ray Binaries with Black Hole X-Ray Binaries

open access: yes, 2013
The study of high-resolution X-ray spectra of neutron star low-mass X-ray binaries (LMXBs) allows the investigation of the innermost parts of the accretion disk and immediate surroundings of the compact object. The weak magnetic eld of old neutron stars present in such systems allows the accretion disk to approach very close to the compact object, like
