Solvent‐Free Manufacturing of Multifunctional Gas Diffusion Electrode Architectures for Enhanced CO2 Conversion From Low‐Concentration Streams

open access: yesAdvanced Functional Materials, EarlyView.
A tandem gas diffusion electrode (GDE) leveraging hierarchically engineered microgranules enables efficient CO2 electroreduction under dilute CO2 conditions. A key innovation lies in the solvent‐free precision assembly of metal–organic‐frameworks, carbon nanotubes, and copper nanoparticles.

The Role of Partial Ionization Effects in the Chromosphere

open access: yes, 2015
The energy for the coronal heating must be provided from the convection zone. The amount and the method by which this energy is transferred into the corona depends on the properties of the lower atmosphere and the corona itself.

Cross‐Layer Molecular Design for Coherent Interface Passivation in Rigid and Flexible Perovskite Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
A cross‐layer passivation strategy employing molecularly designed thiazol‐5‐ylmethanamine hydrochloride (TMACl) enables coherent defect regulation at the SnO2/perovskite interface, stabilizes both layers, promotes phase‐pure α‐FAPbI3 formation, and enhances charge extraction, delivering PCEs of 26.44% in rigid and 24.72% in flexible perovskite solar ...

The impact of solar corpuscular radiation on the Earth's atmosphere: the current state of the problem

open access: yesГеофизический журнал, 2010
Review of results has been given, which approve the hypothesis that solar cosmic rays (SCR) apparently play an important role in ionization of middle and lower atmosphere and may serve as a physical intermediary in solar-terrestrial climatic ...

Overview of HLLV effluents in stratosphere and above [PDF]

open access: yes, 1980
The injection of large quantities of rocket exhaust effluent into the upper atmosphere by the heavy lift launch vehicle (HLLV) of the solar power satellite system is discussed. The exhaust products considered are CO, CO2, H2O, H2, and NO.

X‐Functionality–Driven Photocatalytic Hydrogen Evolution in 2D 4‐X‐PEA2SnI4 Perovskites

open access: yesAdvanced Functional Materials, EarlyView.
We report a water‐based synthesis of 2D 4‐X‐PEA2SnI4 perovskite microcrystals with prominent photocatalytic (PC) activity for H2 production. The synergy between organic functionalization and HI‐derived iodide scavenges holes suppress octahedral distortion, and favor electron accumulation, enabling a PC H2 evolution ∼20 µmol·g−1 and long‐term stability ...
