Super and Massive AGB Stars: II - Nucleosynthesis and Yields - Z=0.02, 0.008 and 0.004 [PDF]
, 2013 We have computed detailed evolution and nucleosynthesis models for super and massive AGB stars over the mass range 6.5-9.0 Msun in divisions of 0.5 Msun with metallicities Z=0.02, 0.008 and 0.004. These calculations, in which we find third dredge-up and hot bottom burning, fill the gap between existing low and intermediate-mass AGB star models and high

Tackling Environmental Impact: A New Support Tool for Sustainable Healthcare Waste Management
Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT This study proposes a novel framework integrating Environmental Risk Assessment (ERA) and Material Flow Analysis (MFA) within the Deming Cycle framework to address this gap. While valuable tools, ERA and MFA offer limited perspectives on environmental impact when used alone.

Electron, EarlyView.Porous coordination polymers (PCPs) or metal–organic frameworks (MOFs) hold promise as photocatalyst candidates for the remediation of toxic metal ions and organic pollutants. However, they often exhibit inferior removal and catalytic efficiency due to the rapid recombination of photoexcited electrons and holes.

A Ray of Hope: Gamma Radiation for Microplastic Remediation
Global Challenges, EarlyView.Gamma irradiation is a promising method for degrading microplastics in sewage sludge. Cobalt‐60 doses up to 116 kGy are used, achieving over two‐thirds degradation at the highest level. With further optimization, gamma irradiation could improve wastewater treatment sustainability by minimizing microplastic presence in biosolids and protecting ...

Mass Spectrometry Reviews, EarlyView.ABSTRACT In the 1980s, researchers discovered the remarkable ability of electrospray plumes to effectively ionize gas‐phase molecules via secondary ionization. Around 20 years later—coinciding with the ambient mass spectrometry revolution—secondary electrospray ionization (SESI) and extractive electrospray ionization (EESI) coupled to mass spectrometry

A record of atmospheric 210Pb accumulation in the industrial city [PDF]
arXiv, 2013 The deposition flux of total atmospheric 210Pb in the industrial city Rostov-on-Don, Russia from 2002 to 2010 has been measured. The variations in annual 210Pb deposition flux appear to be mainly correlated with the number of rains and significant amount of anthropogenic 210Pb, polluted into the surface layer of air in the home-heating period.
