Adaptive Supramolecular Interactions Govern Redox‐Active Molecules in Aqueous Redox Flow Batteries

Advanced Materials, EarlyView.
Adaptive supramolecular interactions overcome the solubility‐stability trade‐off in aqueous redox flow batteries. Hydrophobic anions disrupt intrinsic π–π stacking to enable high solubility, while redox‐state‐dependent spin pairing and cation coordination dynamically stabilize reactive intermediates during operation.

Vibrational resonance in noise-induced structure

, 2002
We report on the effect of vibrational resonance in a spatially extended system of coupled noisy oscillators under the action of two periodic forces, a low-frequency one (signal) and a high-frequency one (carrier).

Wafer‐Scale Direct Growth of Ultraclean Monolayer Amorphous Carbon on c‐Sapphire by Remote Catalytic Dehydrogenation

Advanced Materials, EarlyView.
Remote catalytic dehydrogenation enables the direct growth of monolayer amorphous carbon on a 2‐inch sapphire wafer by thermal CVD. Spatial separation of the catalyst from the growth substrate eliminates metallic residue and post‐growth processing, yielding a wafer‐scale uniform film with a random polygonal sp2‐hybridized carbon network that exhibits ...

Highly Efficient Functionalization of hBN With Lithium Oxalate: A Multifunctional Platform for Composites, Ion Transport, and Spin Labeling

Advanced Materials, EarlyView.
Mechanochemical functionalization of hexagonal boron nitride with lithium oxalate produces LBNCO (Li2(BN)6C2O4${\mathrm{Li}}_{2}{\operatorname{(}\mathrm{BN})}_{6}{\mathrm{C}}_{2}{\mathrm{O}}_{4}$), a layered, intrinsically lithiated material that combines Li+${\rm Li}^+$ transport with high thermal stability and persistent paramagnetic centers.

Vibrational Spectra Of α-ge(hpo4)2· H2o Compound

, 2006
We have measured Raman and infrared spectra of alpha-Ge(HPO4)(2)center dot H2O compound at room temperature. The analysis of vibrational modes indicated the presence of two non-equivalent HPO42- units in agreement with P-31 nuclear magnetic resonance ...

Millifluidic Synthesis of Core–Shell Resonators For Tunable Sonic BandGaps in Acoustic Metamaterials

Advanced Materials Interfaces, EarlyView.
Millimeter‐scale core–shell acoustic resonators are fabricated by a gravity‐assisted dripping approach and incorporated into epoxy composites at controlled volume fractions. The resulting alumina–core resonator composites show tunable low‐frequency acoustic attenuation, demonstrating a scalable route for integrating locally resonant metamaterial units ...

A Self‐Cleaning Solar Evaporator Based on MXene/Aramid Nanofiber Aerogels for Efficient Water Desalination

Advanced Materials Interfaces, EarlyView.
This study develops a self‐cleaning solar evaporator based on MXene‐coated aramid nanofiber aerogels for efficient desalination under high‐salinity conditions. The cylindrical evaporator combines strong photothermal conversion, capillary water transport, and self‐rotation triggered by salt accumulation.

Acoustic Resonance of Microorganisms to Supersonic Vibrations

Experimental Biology and Medicine, 1955
SummarySamples of Paramoecium caudatum, length 207 ± 4.7 μ exposed to supersonic vibrations of low intensity at frequencies from .9 mc/sec. to 5.5 mc/sec. and allowed to multiply for 24 hours, show a response (reduction in multiplication rate) at the frequency expected by acoustic resonance principles, and also at subharmonic frequencies.
