Mapping the Intellectual and Industrial Evolution of Corporate Social Responsibility: A Cross‐Sector Scientometric Analysis Using Main Path and Cluster Methods

Corporate Social Responsibility and Environmental Management, Volume 33, Issue 4, Page 5321-5346, July 2026.
ABSTRACT Corporate social responsibility (CSR) has undergone continuous expansion across industries, yet its intellectual evolution and cross‐sectoral linkages remain insufficiently understood. This study provides a comprehensive, data‐driven assessment of CSR's developmental trajectories by analyzing 3314 Web of Science articles using key‐route main ...

Asymptotic-Giant-Branch Models at Very Low Metallicity [PDF]

Publications of the Astronomical Society of Australia, 2009
AbstractIn this paper we present the evolution of a low-mass model (initial mass M = 1.5 M⊙) with a very low metal content (Z = 5 × 10−5, equivalent to [Fe/H] = –2.44). We find that, at the beginning of the Asymptotic Giant Branch (AGB) phase, protons are ingested from the envelope in the underlying convective shell generated by the first fully ...

Large Deviations of the Giant Component in Scale‐Free Inhomogeneous Random Graphs

Random Structures &Algorithms, Volume 68, Issue 4, July 2026.
ABSTRACT We study large deviations of the size of the largest connected component in a general class of inhomogeneous random graphs with iid weights, parametrized so that the degree distribution is regularly varying. We derive a large‐deviation principle with logarithmic speed: the rare event that the largest component contains linearly more vertices ...

Evidence of Third Dredge-up in Post-AGB Stars in Galactic Globular Clusters

The Astrophysical Journal
To better understand the mixing and mass loss experienced by low-mass stars as they ascend the asymptotic giant branch (AGB), I have gathered from the literature the abundances of CNO and s -process elements in post-AGB stars in Galactic globular ...

A Population of Binaries in the Asymptotic Giant Branch of 47 Tucanae?

The Astrophysical Journal, 2006
We have used a set of archived Hubble Space Telescope/ACS images to probe the evolved populations of the globular cluster 47 Tucanae. We find an excess of Asymptotic Giant Branch (AGB) stars in the cluster core. We interpret this feature as the signature of an extra-population likely made by the progeny of massive stars originated by the evolution of ...

Noble gases and nitrogen in material from asteroid Bennu

Meteoritics &Planetary Science, Volume 61, Issue 7, Page 1593-1609, July 2026.
Abstract We report the elemental and isotopic abundances of all stable noble gases (helium, neon, argon, krypton, and xenon) in eight particles from asteroid Bennu returned by NASA's OSIRIS‐REx mission. We also report nitrogen abundances and isotopic ratios that were analyzed alongside neon and argon in four additional Bennu particles.

Low Mass Stars or Intermediate Mass Stars? The Stellar Origin of Presolar Oxide Grains Revealed by Their Isotopic Composition

Frontiers in Astronomy and Space Sciences, 2021
Among presolar grains, oxide ones are made of oxygen, aluminum, and a small fraction of magnesium, produced by the 26Al decay. The largest part of presolar oxide grains belong to the so-called group 1 and 2, which have been suggested to form in Red Giant

Asymptotic giant branch stars in the Phoenix dwarf galaxy [PDF]

Monthly Notices of the Royal Astronomical Society, 2008
JHKs near-infrared photometry of stars in the Phoenix dwarf galaxy is presented and discussed. Combining these data with the optical photometry of Massey et al. allows a rather clean separation of field stars from Phoenix members. The discovery of a Mira variable (P = 425 days), which is almost certainly a carbon star, leads to an estimate of the ...

Dual‐Functional and Low‐Toxicity ZnO Nanoparticles From Pomegranate Peel: Impact of Synthesis Parameters on Photocatalytic and Supercapacitive Performance

ChemistryOpen, Volume 15, Issue 5, May 2026.
The synthesis of ZnO nanoparticles (NPs) using pomegranate peel extract at ambient temperature represents a significant advancement in the development of sustainable dual‐functional materials. These NPs demonstrated high photocatalytic efficiency in the degradation of organic pollutants and exhibited significant supercapacitive energy storage ...
