μ-Acetato-bis(μ-2-{[(3-chloro-2-hydroxypropyl)(2-pyridylmethyl)amino]methyl}phenolato)dinickel(II) chloride

Acta Crystallographica Section E, 2010
The title salt, [Ni2(C16H18ClN2O2)2(CH3COO)]Cl, features a dinuclear cation in which the Ni atoms are triply bridged by two phenolate O ligands and a bidentate acetate ligand with all of the bridging distances essentially symmetric.

Balancing Hydrophobicity and Hydrophilicity: Dual Filler‐Engineered Proton Exchange Membranes for Durable, High‐Power Fuel Cells

Advanced Functional Materials, EarlyView.
Polarity‐matched Zr–MOFs program Nafion's nanoscale morphology during solution casting. Hydrophilic UiO‐66 preserves hydrated pathways, while hydrophobic UiO‐67 increases the proton hopping sites by densifying ionic clusters. Combining both fillers yields a membrane that delivers 176 mS cm−1 conductivity, reaches 1.46 W cm−2 under 200 kPa, and triples ...

Crystal structures of five gold(I) complexes with methylpiperidine ligands

Acta Crystallographica Section E: Crystallographic Communications
In bis(4-methylpiperidine-κN)gold(I) chloride, [Au(C6H13N)2]Cl (1), the methyl groups are, as expected, equatorial at the piperidine ring, but the Au atom is axial; this is the case for all five structures reported here, as is the expected linear ...

Pressure‐Assisted Dimensional Transformation of 2D Hydrogenated Borophene into 0D Boron Quantum Dots

Advanced Functional Materials, EarlyView.
Hydrogenated borophene (HB) is transformed into distinct boron nanostructures through a solvent‐free thermal process. Under flowing nitrogen, hydrogen escape promotes reconstruction into B2O3 nanoplatelets, whereas hydrogen‐induced pressure under sealed conditions facilitates fragmentation into boron quantum dots.

Crystal structure of the 1:1 adduct of (E)-5-(2,3-dihydrobenzo[d]thiazol-2-ylidene)-2,6-dioxo-4-phenyl-1,2,5,6-tetrahydropyridine-3-carbonitrile and its piperidinium salt, piperidinium (Z)-5-(benzo[d]thiazol-2-yl)-3-cyano-6-oxo-4-phenyl-1,6-dihydropyridin-2-olate

Acta Crystallographica Section E: Crystallographic Communications
In the structure of the title compound, C5H12N+·C19H10N3O2S−·C19H11N3O2S, the central pyridinic rings are approximately coplanar to the benzothiazole moieties. The phenyl groups are appreciably angled to the central rings [interplanar angles of 57.30 (3)°

CO2‐to‐CO Conversion in a Gas‐Fed, Zero‐Gap, PEM Electrolyzer Enabled by Polycations and Nitrogen‐Doped Carbon‐Supported Cobalt Nanoparticles

Advanced Functional Materials, EarlyView.
A gas‐fed, zero‐gap, PEM CO2 electrolyzer is realized by incorporating PDDA+ ions onto the carbonaceous Co/N‐C electrocatalyst, with gaseous H2 and CO2 fed into the anode and cathode, respectively. Operating without an aqueous electrolyte, the system sustains a peak FECO of 65.1% at 100 mA cm−2. ABSTRACT Electrochemical carbon dioxide reduction (ECO2R)

High‐Efficiency Deep Blue Single‐Gaussian Europium(II) Emitters and Their Emitter‐Host Interactions

Advanced Functional Materials, EarlyView.
Crown‐ether ligands and carborate anions enable vacuum‐processable Eu(II) emitters with efficient single‐Gaussian deep‐blue luminescence. Combined photophysical and computational analyses reveal that excited‐electron confinement and steric shielding of the europium center jointly govern compatibility with OLED host materials, establishing molecular ...
