Conversion of CO2‐Derived Amorphous Carbon into Flash Graphene Additives
Macromolecular Materials and EngineeringCO2 emissions have become a significant environmental problem over the last few decades, often stemming from combustion of fossil fuels. Production and disposal of waste plastic also contribute greatly to greenhouse gas emissions, due to combustion of ...

EcoEnergy, EarlyView.A bimetallic NiAg alloy is assembled on the surface of Zn3In2S6 to construct a NiAg‐Zn3In2S6 composite using a chemical reduction method. By adjusting the different alloy ratios, the hydrogen evolution activity of the optimum Ni0.25Ag0.75‐Zn3In2S6 photocatalyst achieves 21.32 mmol·g−1·h−1. ABSTRACT A bimetallic NiAg alloy is assembled on the surface of

Taphonomy of fossilized resins: determining the biostratinomy of amber
Acta geológica hispánica, 2000 Comparing the maturity of fossilized resins with that of their enclosing bedrock can provide information on the maturity, relative age and biostratinomy of amber and copal. A method to determine this is presented here with examples of amber and copal from the Dominican Republic. Maturity of the bedrock was determined by vitrinite reflection and that of

EcoEnergy, EarlyView.A triflate‐functionalized Ni–Ce/MOF–OTf superacid enables low‐temperature (∼140°C) in situ upgrading of ultra‐deep heavy oil. It reduces viscosity by 92.11% in 12 h, maintains activity over cycles, and delivers 90.25% recovery with a lower carbon footprint by selective bond cleavage. ABSTRACT Ultra‐deep heavy oil is an important unconventional resource,

Effect of Sequential and Combined Space‐Based Stressors on Perovskite Solar Cell Stability
EcoEnergy, EarlyView.A correlation between loss in performance and mobile ion concentration has been established by sequential stressing of perovskite solar cells under Low Earth Orbit conditions with exposure to protons, light, and thermal cycling. It is shown that the loss in performance increases when ion concentration increases and vice versa.
