Electroactive Metal–Organic Frameworks for Electrocatalysis

Advanced Functional Materials, EarlyView.
Electrocatalysis is crucial in sustainable energy conversion as it enables efficient chemical transformations. The review discusses how metal–organic frameworks can revolutionize this field by offering tailorable structures and active site tunability, enabling efficient and selective electrocatalytic processes.

Internal waves revisited

Dynamics of Atmospheres and Oceans, 2000
We describe a new laboratory technique that has been developed to examine the structure and amplitude of internal waves. As well as being relatively inexpensive to set up, the technique is sensitive to small density fluctuations: heat rising from a hand can easily be seen.

Tomographic reconstruction of internal wave patterns in a paraboloid

, 2011
Using tomographic synthetic schlieren, we are able to reconstruct the three-dimensional density field of internal waves. In this study, the waves are radiating from an oscillating sphere positioned eccentrically at the surface of a paraboloidal domain ...

Magnetic Control of Chiral Hybridized Phonon Magnetic Moments in Ferrimagnets Fe2‐xZnxMo3O8

Advanced Functional Materials, EarlyView.
Helicity‐resolved magneto‐Raman spectroscopy reveals magnetic control of chiral phonon magnetic moments in polar ferrimagnet (ZnxFe2−xMo3O₈). Large spontaneous zero‐field phonon splittings, selective phonon–magnon coupling, and asymmetric Zeeman responses demonstrate that phonon chirality is governed by magnon‐phonon coupling and magnetization.

Internal Waves and Waves of Sand [PDF]

Nature, 1960
A DESCRIPTION has been given of some large sand waves on La Chapelle Bank which lie parallel to the general direction of the edge of the continental shelf1. They occur within a zone about 10 miles wide, have a mean separation of 2,800 ft. and are up to 40 ft. high.

An All‐Optical Driven Bio‐Photovoltaic Interface for Active Control of Live Cells

Advanced Functional Materials, EarlyView.
Bio‐photovoltaic Interface (BIO‐PV‐I) for live cell manipulation is presented. BIO‐PV‐I can be activated non‐invasively and remotely to control the spatial motility, adhesion, and morphology of cells adhering to it. BIO‐PV‐I uses a patterned light‐induced electric potential in iron‐doped lithium niobate crystals whose light‐driven and reversible nature,

Dynamic response of viscoelastic foundation beams under traveling wave effect

Yantu gongcheng xuebao, 2020
The dynamic problem of elastic foundation beams is usually analyzed by using the analytical and numerical methods, but the numerical method has a large amount of calculation, and the analytical method is usually more efficient.

Circular‐Polarization‐Sensitive Organic Photodetectors with a Chiral Nanopatterned Electrode Inverse‐Designed by Genetic Algorithm

Advanced Functional Materials, EarlyView.
A chiral photodetector capable of selectively distinguishing left‐ and right‐handed circularly polarized light is experimentally demonstrated. The device, which features a nanopatterned electrode inverse‐designed by a genetic algorithm within a metal–dielectric–metal nanocavity that incorporates a vacuum‐deposited small‐molecule multilayer, exhibits ...

Himawari sea surface temperature data reveal regular internal wave activity producing cooling in the northern South China Sea

Frontiers in Marine Science
Internal wave (IW) events occur rapidly and have a short duration, but they have a great impact on nearshore ecosystems. To address the problems of short observation time, limited range based on measured data, and low accuracy based on mesoscale ...

Analysis of the Scattering Characteristics of Sea Surface with the Influence from Internal Wave

Leida xuebao, 2015
The internal wave travels beneath the sea surface and modulate the roughness of the sea surface through the wave-current interaction. This makes some dark and bright bands can be observed in the Synthetic Aperture Radar (SAR) images.
