The Application of Carbon Dots in Crops for Sustainable Agriculture

ChemistryEurope, EarlyView.
Carbon dots serve as versatile nanoagents across the crop life cycle. They promote plant growth and photosynthesis, enhance resilience to biotic and abiotic stresses, aid in postharvest preservation, and enable sensitive detection of contaminants.

Five New Sirius-like White Dwarf–Main-sequence Star Systems with MagAO-X

The Astronomical Journal
Most known white dwarfs in multiple systems with main-sequence stars have been discovered with M-type companions, because the white dwarf causes detectable UV excess and bluer colors than expected from a single M star.

“Train and Hope”: The Role of Restorative Justice Coordinators in Sustaining a Culture of Care in Schools

Conflict Resolution Quarterly, EarlyView.
ABSTRACT This article examines the role of restorative justice coordinators in supporting teachers and schools in adopting a whole‐school approach to restorative justice in education. Coordinators are often tasked with implementing a train‐and‐hope model, in which they receive initial training in restorative justice but are largely left unsupported ...

Searching for benchmark systems containing ultra-cool dwarfs and white dwarfs

EPJ Web of Conferences, 2013
We have used the 2MASS all-sky survey and WISE to look for ultracool dwarfs that are part of multiple systems containing main sequence stars. We cross-matched L dwarf candidates from the surveys with Hipparcos and Gliese stars, finding two new systems ...

Axions and White Dwarfs

, 2010
White dwarfs are almost completely degenerate objects that cannot obtain energy from the thermonuclear sources and their evolution is just a gravothermal process of cooling.

Social Media Green Marketing: How Self‐Monitoring Shapes Consumer Engagement and Eco‐Purchase Intentions

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Marketing scholars and practitioners are paying increasing attention to social media as a crucial tool for communicating firms' sustainable activities to consumers. This study examines how consumers perceive and engage with social media green marketing, and how their engagement influences their intentions to purchase green products and brands,

The neutrino emission due to plasmon decay and neutrino luminosity of white dwarfs

, 2007
One of the effective mechanisms of neutrino energy losses in red giants, presupernovae and in the cores of white dwarfs is the emission of neutrino-antineutrino pairs in the process of plasmon decay. In this paper, we numerically calculate the emissivity

White dwarf variability

There are a few different mechanisms that can cause white dwarf stars to vary in brightness, providing opportunities to probe the physics, structures, and formation of these compact stellar remnants. The observational characteristics of the three most common types of white dwarf variability are summarized: stellar pulsations, rotation, and ellipsoidal ...
