Rheological Properties of Bitumen and Bitumen-Heptane and Bitumen-Heptanol Mixtures
, 2021 The rheological changes and high viscosity of bitumen, arising from high molecular weight molecules in bitumen, are the main challenges for its production to the surface and its transportation in pipelines. To solve the environmental issues associated with bitumen recovery, such as greenhouse gas emissions from steam-based recovery processes, solvent ...

Carbon Energy, EarlyView.Dual‐nickel atom catalysts (Ni‐DACs) are developed to stabilize unsaturated Ni─N3 atomic sites by constructing N3Ni─NiN3 dual‐atom structures from coal. Benefiting from the modulated electronic structure that optimizes intermediate adsorption, Ni‐DACs outperform Ni‐SACs in CO2 electroreduction, achieving a max FECO of 98.6% at −0.8 V vs RHE and a TOF ...
