Controlled Aggregation of Pyrene‐Based Supramolecular Nanostructures for Light‐Driven Switchable H2 or H2O2 Production

Advanced Functional Materials, EarlyView.
This work reports the self‐assembly of a pyrene derivative into two distinct nanostructures and their application in visible‐light photocatalysis. The two nanostructures exhibit completely different yet complementary photocatalytic activities, promoting either H2 or H2O2 evolution.

The Orbital Period of the Long-period and Colliding-wind Binary WR 146 from Radio Interferometry of the Shock Cone

The Astronomical Journal
We report the first measurement of the orbital period of a long-period colliding-wind-binary system Wolf–Rayet (WR) 146, derived by tracing the rotational morphology of its wind-colliding region (WCR) and the relative orientation of the two binary ...

MAXI J1659-152: the shortest orbital period black-hole transient in outburst [PDF]

, 2012
MAXI J1659−152 is a bright X-ray transient black-hole candidate binary system discovered in September 2010. We report here on MAXI, RXTE, Swift, and XMM-Newton observations during its 2010/2011 outburst.

Primary Orbital Lymphoma – A Challenging Diagnosis

Acta Medica Bulgarica, 2020
Background and purpose: The occurrence of primary orbital lymphoma comprises approximately 1% of non-Hodgkin’s lymphoma and 8% of extranodal lymphoma. The vast majority of orbital lymphomas are of B-cell origin, of which extranodal marginal zone B-cell ...

CCD Photometric Investigation of A W UMa-Type Binary GSC 0763-0572

, 2012
A photometric solution of an A-type W UMa binary, GSC 0763-0572 is examined with a revised orbital period. The overcontact degree is found to be $f$ = 40.66%, with a low mass ratio of $q$ = 0.2554.

Near‐Infrared Emitting Lanthanide Catecholate Giant Single Crystals – Morphology Control and Photon Down‐Conversion

Advanced Functional Materials, EarlyView.
Controlled syntheses of lanthanide coordination polymers based on the dihydroxybenzoquinone (DHBQ) organic linker afforded large single crystals of Ln‐DHBQ CPs (Ln = Yb, Nd). A novel structural variant of Yb‐DHBQ is identified by means of single crystal diffraction analysis.
