Observation of Two‐Photon Resonant Raman Scattering via the Biexciton Level in Two‐Dimensional Halide Perovskite (C6H5C2H4NH3)2PbI4

open access: yesAdvanced Functional Materials, EarlyView.
Efficient two‐photon resonant Raman scattering (TRRS) is observed in the layered perovskite (PEA)2PbI4, with the biexciton level acting as an intermediate state. TRRS undergoes two‐photon frequency shift upon input frequency tuning, persists up to 90 K, and shows clear threshold behavior and polarization selection rules.

Effect of Anharmonicity on the Kondo Phenomena of a Magnetic Ion Vibrating in a Confinement Potential

open access: yes, 2011
Effect of anharmonicity of a cage potential for a magnetic ion vibrating in a metal is investigated by the numerical renormalization group method. The cage potential is assumed to be one-dimensional and of the double-well type.

Assembly of Cell‐Seeded 3D Printed Hydrogel Modules with Perfusable Channel Networks

open access: yesAdvanced Functional Materials, EarlyView.
Macroscale assembly was utilized to prepare perfusable tissue constructs from individually 3D printed hydrogel modules with embedded branched channel networks and port arrays for cell seeding. Novel multi‐material bioreactors were fabricated to facilitate the gluing of individual modules and the perfusion culture of assembled modular constructs seeded ...

Geological and glaciological controls of 21,700 active methane seeps in the northern Norwegian Barents sea

open access: yesFrontiers in Earth Science
Due to tectonic uplift in the Cenozoic and numerous shelf-wide glaciations during the Quaternary, ∼1–2.5 km of sedimentary overburden has been eroded from the Barents Sea shelf, leading to the exhumation and partial uncapping of hydrocarbon accumulations.

A Host‐Guest, Zeolite/Organocation Material With Isotropic Zero Thermal Expansion

open access: yesAdvanced Functional Materials, EarlyView.
The use of selected organic structure directing agents for the hydrothermal synthesis of targeted zeolites exhibiting negative thermal expansion provides a straightforward strategy to obtain a new class of host‐guest, nanostructured, crystalline zero thermal expansion materials made of light and abundant elements.

Structural and Chemical Engineering of Sub‐Nanochannel Membranes Toward Ion Selectivity

open access: yesAdvanced Functional Materials, EarlyView.
This review summarizes recent advances in structural and chemical engineering of sub‐nanochannels for ion selectivity. We first introduce fundamental ion transport mechanisms within sub‐nanochannels, followed by strategies to tune pore size, geometry, and surface functionalities, categorized into charge‐based, ion‐recognition, hydrophilic bonding, and ...
