Advanced Engineering Materials, EarlyView.Selenium was incorporated into a sol–gel‐derived bioactive glass to enable sustained therapeutic ion release. The selenium‐containing glass preserved bioactivity while selectively inducing cytotoxicity in osteosarcoma cells and maintaining osteoblastic viability.

The Astrophysical JournalThe rising phase toward the optical maximum of a classical nova is one of the last frontiers of nova study. Constructing free–free emission model light curves based on our fully self-consistent nova explosion models, we present several theoretical light ...

Optical observations of the fast nova V1674 Herculis
Monthly Notices of the Royal Astronomical SocietyABSTRACT We present the evolution of optical spectra and light curves of the fast nova V1674 Herculis during 150 d past its eruption. Using the post-eruption AAVSO light curve, we have calculated the orbital period of V1674 Her to be 0.153 d. There is no unambiguous white dwarf spin period in our data.

Spectropolarimetric Evidence of Asymmetric Outburst in the Fast Nova V1494 Aquilae
The Astrophysical Journal, 2001 We present our extended polarimetric observations of a fast nova from the premaximum to transition stages. The observations were made for V1494 Aquilae (=Nova Aql 1999 No. 2) at the Dodaira Observatory of the National Astronomical Observatory of Japan between 1999 December 2 and 2000 March 29. We discovered that the light from the nova had already been

The critical mass ratio for W UMa-type contact binary systems [PDF]
Serbian Astronomical JournalContact binaries are close binary systems in which both components fill their inner Roche lobes so that the stars are in direct contact, and in potential mass and energy exchange.

X-ray monitoring of classical novae in the central region of M31. III. Autumn and winter 2009/10, 2010/11 and 2011/12 [PDF]
, 2014 [Abridged] Classical novae (CNe) represent the major class of supersoft X-ray sources (SSSs) in the central region of our neighbouring galaxy M31. We performed a dedicated monitoring of the M31 central region, aimed to detect SSS counterparts of CNe ...

The Rise of Nova V1674 Herculis
The Astrophysical JournalObservational constraints on classical novae are heavily biased to phases near optical peak and later because of the simple fact that novae are not typically discovered until they become bright. The earliest phases of brightening, coming before discovery,
