Experimental Study on Laminar Burning Velocity and Flame Instability of Liquefied Petroleum Gas/Dimethyl Ether Blended Gas: Effects of Equivalence Ratio and Blended Ratio

Safety Science and Technology, EarlyView.
This study reveals the regulatory effect of LPG addition on laminar burning velocity of DME/air mixtures, and elucidates the governing mechanisms of flame instability under varying initial conditions. ABSTRACT Liquefied petroleum gas/dimethyl ether (LPG/DME) blended gas is a promising clean alternative fuel, characterized by high efficiency and clean ...

In Situ Construction of Phosphorus‐Containing Crosslinked Urethane Network Combined With Ammonium Polyphosphate via Reactive Blending for Enhancing Flame Retardancy and Anti‐Dripping Performance of Polylactic Acid Composites

Safety Science and Technology, EarlyView.
By in situ reaction blending, DOPO‐HQ and THEIC were added to PLA with MDI to construct a phosphorus containing polyurethane network, which significantly improved the flame retardant and anti‐dripping properties of polylactic acid composites. ABSTRACT Polylactic acid (PLA) is highly flammable and prone to severe melt dripping during combustion, which ...

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

The 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 ...

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

Environmental 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 ...

How to stay wild in a highly domesticated landscape? Spatiotemporal behaviour of wolves in Germany

Wildlife Biology, EarlyView.
Wild animals can adapt to the increasing presence of humans by either becoming accustomed to it or by avoiding humans by spatiotemporal separation. The return of the wolf to the German lowlands raised the opportunity to study wolf behaviour in one of the most densely populated and fragmented countries in Europe, in an area where topography offers no ...

[Energy requirements of miners engaged in open-pit coal mining].

Voprosy pitaniia, 1988
It has been found that according to the value of daily energy consumption the coal miners engaged in open-cast mining should be referred to group III-IV of work intensity. The determining component of daily energy consumption is energy consumption during the working period the value of which depends on the character of working activity and duration of ...

Application of Intelligent Systems in CO2 Management: State of the Art and Future Prospects

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Machine learning (ML) integration is becoming increasingly popular in advancing the 4th industrial revolution, known as Industry 4.0. This review paper examines ML applications in CO2 management stages: emission, capture, and conversion. ML models, including multiple linear regression (MLR), multiple nonlinear regression (MNLR), and artificial

Investigation of the Evolution Mechanism and Multiphysics Coupling in Tree‐Contact Single‐Phase‐to‐Ground Fault

High Voltage, EarlyView.
ABSTRACT Tree‐contact single‐phase‐to‐ground fault (TSF) is a common and hazardous type of failure in distribution networks. TSF is likely to occur when overhead conductors contact moist tree branches, potentially leading to insulation breakdown, posing serious threats to grid safety.
