The objective for this research was to utilize hybrid amine doped with Fe2O3 nano-particles for absorbing CO2. The nano-fluid was examined for optimizing the desorption rate as well as the regeneration percent of the solvent ...

Recently, there have been increasing challenges in handling surplus biomass such as barley straw, and technologies that utilize these materials to create high value-added resources, such as electrode materials, are gaining ...

The tire antioxidant 6PPD transforms into the toxic 6PPD-quinone (6PPDQ, e.g., LC50 < 1 μg/L for sensitive aquatic species) via ozonation. However, its fate in ozone-free aqueous systems remains poorly understood. This ...

Biogas purification is essential for mitigating corrosion and environmental risks associated with acidic impurity gases. In this study, yeast–alginate hydrogel composite biosorbents prepared by Ca2+ gelation followed by ...

Bioleaching is regarded as an environmentally sustainable process for recycling spent lithium-ion batteries (LIBs). However, at high pulp densities, its application becomes challenging due to reduced microbial activity ...

To deeply investigate the micro-scale seepage characteristics and the influence law of rock physical properties in complex fluvial facies oilfields during the high water-cut later stage, as well as the mechanism of sweep ...

The development of deep coalbed methane requires large-scale hydraulic fracturing, which prompts the establishment of adsorption prediction models that take into account the influence of fracturing fluids. Based on the ...

The main objective of this work is to optimize the yield (metal recovery) of the separation of magnetite ore using the shaking table. Two methods were used for optimization: experimental designs and genetic algorithms. We ...

The deep shale gas resources in southern Sichuan province of China are abundant, accounting for over 80% of the total shale gas resources in the region. However, influenced by the superimposition of multiple tectonic ...

One of the important parameters in underground carbon dioxide storage is the CO2-brine interfacial tension (IFT). Although previous studies have estimated this parameter using machine learning methods, many methods have ...
