Response surface optimizing XG/HPMC fly ash colloid to inhabit coal spontaneous combustion: An experimental study

open access: yesCase Studies in Thermal Engineering
Fly ash grouting is an effective technical to prevent the coal spontaneous combustion. However, fly ash slurry has its problems such as being prone to sedimentation and not easy to solidify, which has a negative impact on the prevention and control of ...

Bacterial healing of cracks in metakaolin‐based geopolymer concrete exposed to high temperatures

open access: yesStructural Concrete, EarlyView.
Abstract This study examined the bacterial healing of metakaolin‐based geopolymer concrete modified with colemanite (K) and red mud (RM) exposed to high temperatures. The metakaolin‐based geopolymer concrete samples modified with 4% K and 6% RM were prepared.

Treatment of fly ash from power plants using thermal plasma

open access: yesBeilstein Journal of Nanotechnology, 2017
Fly ash from power plants is very toxic because it contains heavy metals. In this study fly ash was treated with a thermal plasma. Before their treatment, the fly ash was analyzed by many technics such as X-ray fluorescence, CHN elemental analysis ...

Geopolymers as a Sustainable Chemical Platform: From Building Materials to Advanced Functional Applications

open access: yesThe Chemical Record, EarlyView.
Geopolymers are presented as a chemically programmable platform whose properties emerge from activation chemistry, nanoscale disorder, and interfacial design. The review highlights sustainability challenges, the shift toward nanoengineered and hybrid systems, and the rise of halloysite‐based architectures enabling tunable structures across scales for ...

Spheroidal Carbonaceous Fly Ash Particles Provide a Globally Synchronous Stratigraphic Marker for the Anthropocene

open access: yes, 2015
Human impacts on Earth are now so great that they have led to the concept of a new geological epoch defined by this global human influence: the Anthropocene. While not universally accepted, the term is increasingly popular and widely used.

Variation on Toxic and Inflammatory Potential of Coal Smoke of Different Sources From a Region With High Lung Cancer Risk

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Excess lung cancer risk in Xuanwei and Fuyuan, China, has been attributed to household air pollution from use of a locally sourced smoky (bituminous) coal. However, the carcinogenic mechanisms remain unclear. Given the important role of inflammation in lung cancer development, this study compared the proinflammatory potentials of the ...

Quantifying microhabitat selection of snowshoe hares using forest metrics from UAS‐based LiDAR

open access: yesWildlife Biology, EarlyView.
Identifying the spatial and temporal scale at which animals select resources is critical for predicting how populations respond to changes in the environment. The spatial distribution of fine‐scale resources (e.g. patches of dense vegetation) are often linked with critical life‐history requirements such as denning and feeding sites.
