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.

Cretaceous mycelia preserving fungal polysaccharides: taphonomic and paleoecological potential of microorganisms preserved in fossil resins

Geologica Acta, 2015
The cortices of pieces of Cretaceous amber around the world commonly are constituted by networks of filamentous structures. Based on their morphological characteristics, such structures have previously been classified in different microorganismal groups.

Phenolic Resin‐Functionalized NH2‐UiO‐66‐Containing Mixed Matrix Membranes for CO2/CH4 Separation

EcoEnergy, EarlyView.
Phenolic resin‐functionalized small‐size RFin@NH2‐UiO‐66 nanofillers were prepared and combined with polyetherimide (PEI) matrix to construct mixed matrix membranes for effective CO2/CH4 separation. ABSTRACT For mixed matrix membranes (MMMs), the inherent structural features and composition of the embedded nanofillers play a pivotal role in governing ...

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

A Biosourced and Self‐Healable Polymer Electrolyte for Potassium Batteries

EcoEnergy, EarlyView.
A biosourced lignin‐filled gel polymer electrolyte combines suppressed crystallinity, high ionic conductivity, and UPy‐driven self‐healing for potassium batteries. The optimized formulation sustains long‐term cycling with 97.5% capacity retention after 1000 cycles and preserves electrochemical operation after intentional membrane damage.

2D/2D/2D Metallic 1T Phase WS2/TiO2/Ti3C2Tx MXene Ternary Composite for Synergistically Enhanced N2 Electroreduction

EcoEnergy, EarlyView.
TiO2 nanosheets were in situ grown on Ti3C2Tx MXene, and then 1T phase WS2 was distributed on TiO2/Ti3C2Tx MXene to form 1T‐WS2/TiO2/Ti3C2Tx MXene, which exhibits a prominent NH3 yield of 46.27 μg h−1 mg−1cat. at −0.8 V versus RHE and a superior FE of 69.26% at −0.65 V versus RHE.
