A new mass-ratio for the X-ray Binary X2127+119 in M15?
, 2004 The luminous low-mass X-ray binary X2127+119 in the core of the globular cluster M15 (NGC 7078), which has an orbital period of 17 hours, has long been assumed to contain a donor star evolving off the main sequence, with a mass of 0.8 solar masses (the ...

Commissioning an Inexpensive Off‐The‐Shelf Spectrograph for Radial‐Velocity Studies
Astronomische Nachrichten, EarlyView.ABSTRACT We present a way to set up an inexpensive out of the shelf spectrograph at a local observatory. Stability and resolution of the spectrograph are high enough for radial velocity determination of binary stars or determination of stellar characteristics. Even some exoplanets might be detectable via the radial velocity method.

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.A donor–acceptor (D–A) engineering strategy is applied to construct β‐ketoenamine‐linked COFs for CO2 photoreduction in pure water without sacrificial agents or photosensitizers. The designed TP‐TAPB COF, featuring the strongest D–A interaction, achieves a complete CO production rate of 464.6 μmol g−1. Strengthened intramolecular D–A interactions favor

Decentralized Wind Energy Systems as Catalysts for Urban Resilience: A Design Framework
Energy Science &Engineering, EarlyView.ABSTRACT Confronting the escalating extreme weather events (EWEs) and intensifying winds, this study proposes an active response to these issues by exploring decentralized wind energy production for Peng Chau Island, Hong Kong. It integrates theoretical perspectives on energy democracy—empowering local communities through energy autonomy—and urban ...

Natural Sciences, EarlyView.Lead‐based perovskite solar cells deliver outstanding power conversion efficiencies, yet their commercialization is constrained by concerns over lead toxicity and stability challenges. Advanced encapsulation and chemical passivation techniques can significantly suppress lead leakage while improving long‐term device stability.
