On the production of heavy neutron-rich isotopes during He and C burning in massive stars
, 1986 The main purpose of this lecture is a re-examination of the yields of s-elements by massive short-lived stars. He-burning conditions are reviewed and results are presented for the nucleosynthesis in this phase. The authors briefly analyse the possibility

Fundamental parameters of massive stars
, 2004 We discuss the determination of fundamental parameters of "normal" hot, massive OB-type stars, namely temperatures, luminosities, masses, gravities and surface abundances.

Advanced Functional Materials, EarlyView.For the first time, an extreme‐thick laser‐arc PVD ta‐C (DLC) coating exceeding 100 µm is demonstrated, opening up new possibilities for ultra‐high load bearing capacity. This superhard amorphous carbon architecture combines >50% sp3 bonding, robust adhesion and self‐supporting performance, shielding substrates from plastic flow under extreme contact ...

Massive stellar cannibals: How stellar mergers drive mass loss in extremely massive stars
Astronomy & AstrophysicsContext. It has been theorized that the formation of extremely massive and supermassive stars (> 103 M⊙) could plausibly be the outcome of stellar mergers in low metallicity (Z 1000 M⊙ with inspiraling companions of < 100 M⊙; hence, with mass ratios of <

Advanced Functional Materials, EarlyView.Combining field‐effect surface passivation of a narrow‐bandgap tin–lead perovskite by diammonium ions with introducing oleyl‐based amphiphiles to create insulating interface layers between the absorber and the adjacent hole and electron transporting layers increases the open‐circuit voltage to 91.5% of the detailed‐balance limit and enhances the power ...

Modeling the Progenitor Stars of Observed Type IIP Supernovae
The Astrophysical JournalType IIP supernovae (SNe IIP) are thought to originate from the explosion of massive stars >10 M _⊙ . Their luminosity is primarily powered by the explosion energy and the radioactive decay energy of ^56 Co, with the photosphere location regulated by ...

Spectroscopy of Massive Stars [PDF]
, 2006 peer reviewedAlthough rare, massive stars, being the main sources of ionizing radiation, chemical enrichment and mechanical energy in the Galaxy, are the most important objects of the stellar population. This review presents the many different aspects of

Configuration‐Encoded Cell Alignment by Light‐Gated Silicon Photovoltaic Microcell Arrays
Advanced Functional Materials, EarlyView.Light‐gated silicon photovoltaic microcells convert pulsed illumination into localized electrical cues. Arranging otherwise similar microcells into four‐lobed, six‐lobed, or circular patterns directs fibroblasts into corresponding local arrangements without wired stimulation.

Advanced Healthcare Materials, EarlyView.Single‐cell and spatially resolved impedance mapping using a high‐density CMOS‐MEA platform enables non‐invasive monitoring of osteoarthritis‐associated chondrocyte dynamics. Continuous label‐free measurements reveal heterogeneous remodeling behaviors, including proliferation, migration, and phenotypic transitions, establishing a powerful approach for ...
