The Effect of Water Management and Cell Compression in Bipolar Membrane CO2 Electrolysis to CO

open access: yesCarbon Energy, EarlyView.
In‐operando neutron imaging uncovers water management challenges in bipolar membrane CO2 electrolysis: Internal water generation floods the cathode, while compression dictates membrane and gas diffusion electrode integrity. Strategic adjustments are applied in this work: dry gas feed and mechanical support of the gas diffusion electrode enable stable ...

Transitioning Formamide Solvothermal Syntheses of MOFs to Less Toxic Solvents

open access: yesChemistry – A European Journal, EarlyView.
Metal‐organic Frameworks (MOFs) are commonly synthesized in toxic formamide solvents. This study investigates the synthetic factors required for effective removal of formamides across various classes of MOFs, providing a foundation for designing new sustainable MOF syntheses.

Tetradecanuclear {Ni9Ln5} Clusters Featuring Encapsulated {Ln5} Trigonal Bipyramids: Modular 3d‐4f Architectures With Broad‐Range Magnetocaloric Response

open access: yesChemistry – A European Journal, EarlyView.
The use of 2‐aminoisobutyric acid in 3d–4f chemistry affords three {Ni₉Ln5} clusters, with the Gd analogue exhibiting an unusually broad magnetocaloric effect across an extended temperature range. ABSTRACT The solvothermal reaction between Ni(HCOO)2.2H2O, 2‐aminoisobutyric acid (aibH), Ln(OAc)3·4H2O (Ln = Gd, Y, Dy) and NEt3 in MeOH/MeCN affords the ...

Effects of Biotin on a Fluorescein‐Based Photosensitizer Revealed by Multiscale Computational Modeling

open access: yesChemistry – A European Journal, EarlyView.
Biotinylation of a fluorescein‐based photosensitizer enhances its performance in PDT through a synergistic dual action. In addition to Type II singlet oxygen generation common to both dyes, the biotinylated system induces stronger membrane perturbation and higher local accumulation in lipid membranes, associated with increased water permeability and ...

The Rich Chemistry of Ionized Methanol With Sulfur Dioxide: Pathways to Prebiotic and Elusive Species in Earth's Atmosphere and Space

open access: yesChemistry – A European Journal, EarlyView.
The reaction between the methanol radical cation and sulfur dioxide is remarkably fast and forms several ionic and neutral products (HOSOH+, CH2OSO+, CH2OH+, CH2O, H2O, HSO2). The chemistry goes beyond simple proton or hydrogen transfer, revealing a close interaction between the two species, relevant to atmospheric and astrochemical environments where ...
