Performance Constraints of All‐Perovskite Tandem Solar Cells in Low‐Intensity, Low‐Temperature Environments

open access: yesAdvanced Materials, EarlyView.
All‐perovskite tandem solar cells are evaluated under low‐intensity and low‐temperature (LILT) conditions relevant to space environments. Distinct loss regimes emerge, where weaker entropic mixing causes halide segragation below ≈240 K going along with a strong current imbalance, while poor electron transport in C60 dominates.

Crude oil desulfurization [PDF]

open access: yes, 1982
High sulfur crude oil is desulfurized by a low temperature (25-80 C.) chlorinolysis at ambient pressure in the absence of organic solvent or diluent but in the presence of water (water/oil=0.3) followed by a water and caustic wash to remove sulfur and ...

An Integrated Stainless Steel‐Based Electrode for Durable Direct Natural Seawater Electrolysis

open access: yesAdvanced Materials, EarlyView.
We report an integrated stainless steel‐based electrode featuring Pt atomic clusters anchored on a NiFe‐LDH anticorrosive layer. By regulating interfacial water dynamics to suppress chloride attack, this hierarchical architecture achieves superior durability (over 1000 h) and energy efficiency in direct seawater electrolysis, offering a cost‐effective ...
