Mineralogical and elemental analysis of Kazakh coals from three mines: Preliminary insights from mode of occurrence to environmental impacts

Open Geosciences
This study aims to comprehensively characterize coal extracted from three active mines in northeastern Kazakhstan: Lenin, Saradyr, and Bogatyr. These mines exploit two Carboniferous coal-bearing formations, Dolyn and Karagandy.

Immunoinformatics‐Based Design of a Multi‐Epitope Vaccine Targeting a Conserved Copper–Associated Protein in Neisseria gonorrhoeae

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Neisseria gonorrhoeae poses an urgent public health challenge due to rapidly increasing antimicrobial resistance and the absence of an effective vaccine. Targeting conserved bacterial pathways involved in essential physiological processes may provide new opportunities for vaccine antigen discovery.

Microbial community structure and potential functional diversity in a post-mining ecosystem of central China

Frontiers in Environmental Science
Abandoned coal mines cause severe soil degradation, water pollution, and biodiversity loss. This study characterizes microbial community dynamics across distinct microhabitats—slag-enriched soil (D-1), waterlogged sediment (W-3), and acidic wastewater (W-

From Green Governance to Biodiversity Strategy: The Role of Environmentally Experienced Directors in Chinese Firms

Business Strategy and the Environment, EarlyView.
ABSTRACT This study investigates how directors with environmental protection (EP) backgrounds influence corporate biodiversity concern (BIO) among Chinese A‐share listed firms from 2008 to 2023. Drawing on Upper Echelons Theory, we argue that directors' environmental expertise shapes firms' biodiversity strategies.

Board Networks and Corporate Carbon Emissions: A Cross‐Country Analysis of Causal Effects

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines whether board networks influence corporate carbon emissions and the strategic pathways through which firms decarbonize. Using a sample of 1952 firms across 48 countries from 2003 to 2020, we employ dynamic stacked regressions that exploit exogenous carbon‐regulation shocks affecting firms connected through shared third ...

Study of Sulfur Purification from Bituminous Material in The Mishraq Sulfur Mine Using Acidic Sulfur Waste (Foam)

Journal of the Turkish Chemical Society Section A: Chemistry
In conclusion, the sulfur wastes obtained from chemical and thermal methods for sulfur purification in the Mashreq field has been present for decades in significant quantities, approaching two million tons, with its harmful impact on the environment. Our research focused on using a different approach by utilizing the acidic sulfur wastes (foam) as a ...

Beyond Carbon: Corporate Environmental Performance Across Multiple Domains

Business Strategy and the Environment, EarlyView.
ABSTRACT We examine corporate environmental performance (CEP) as a multidimensional system rather than isolated outcomes. Combining institutional and behavioral perspectives, we analyze four domains—CO2 emissions, waste, energy, and water—using S&P 500 firms that disclosed data on all four domains (2006–2024).
