Recent Advances in Wide‐Bandgap Perovskite Solar Cells
Advanced Materials, EarlyView.Ubiquitous defects predominately account for photo‐instability and open‐circuit voltage losses in wide‐bandgap perovskite solar cells (WBG PSCs). This review comprehensively presents the underlying impact mechanisms, summarizes the advanced optimization strategies across various functional layers and their interfaces to develop efficient and stable WBG

The Na-O anticorrelation in horizontal branch stars - I. NGC 2808 [PDF]
, 2011 The chemical composition of horizontal branch (HB) stars might help to clarify the formation history of individual globular clusters (GCs). We studied the Na-O anti-correlation from moderately high resolution spectra for 91 stars on the bimodal HB of NGC

Evolution of horizontal branch stars with extension [PDF]
Astrophysics and Space Science, 1990 The details of the evolution of a low-mass horizontal branch star through the asymptotic giant phase with the assumption of first an extended atmosphere and second with extended and mass including atmosphere are given in comparison with the evolution of the same model without extension. © 1990 Kluwer Academic Publishers.

POSSIBLE IMPLICATIONS OF THE PLANET ORBITING THE RED HORIZONTAL BRANCH STAR HIP 13044 [PDF]
, 2011 We propose a scenario to account for the surprising orbital properties of the planet orbiting the metal-poor red horizontal branch star HIP 13044. The orbital period of 16.2 days implies that the planet went through a common envelope phase inside the red

Advanced Materials Interfaces, EarlyView.Their research explores van der Waals magnets and uses a perpendicularly magnetized FGT/O‐FGT/hBN heterostructure to demonstrate gate voltage‐controlled magnetization switching. They observe bidirectional voltage control of exchange bias (EB), with the highest EB magnitude of 1.4 kOe and a blocking temperature of 150 K, both among the highest for ...

Interactive soybean variable‐rate seeding simulator for farmers
Agronomy Journal, Volume 114, Issue 6, Page 3554-3565, November/December 2022., 2022 Abstract Seed expense is a critical component affecting soybean (Glycine max L.) production cost. Achieving potential benefits of adjusting seeding rates by yield environment requires translation from theory to practice through decision support tools.

The empirical mass distribution of hot B subdwarfs: Implications for stellar evolution theory
EPJ Web of Conferences, 2013 Subdwarf B (sdB) stars are hot, compact, and evolved objects that form the very hot end of the horizontal branch, the so-called Extreme Horizontal Branch (EHB).

Horizontal Branch Stars and the Ultraviolet Universe [PDF]
, 2009 Extremely hot horizontal branch (HB) stars and their progeny are widely considered to be responsible for the "ultraviolet upturn" (or UVX) phenomenon observed in elliptical galaxies and the bulges of spirals. Yet, the precise evolutionary channels that lead to the production of these stars remain the source of much debate.
