Phase Engineering of Atomically Precise Nanoclusters (APNCs) of Gold and Beyond

Advanced Materials, EarlyView.
Engineering the structural phase of materials is of paramount importance for both fundamental research and practical applications. In this Review, we summarize the recent progress in controlling the phases of atomically precise nanoclusters (APNCs) of gold, silver and copper, as well as bimetallic systems. The phase‐enabled material properties of APNCs

Diagnosis of the solar atmosphere using solar oscillations [PDF]

Symposium - International Astronomical Union, 1988
I present a review of the art of using acoustic and gravity waves as a tool to probe the structure of the solar atmosphere. The principle ideas behind the technique are discussed and a small bouquet of results is presented. The current discrepancies are pointed out, and in the last section a few thoughts are let loose about the inversion of data to ...

Generating Unconventional Spin‐Orbit Torques With Patterned Phase Gradients in Tungsten Thin Films

Advanced Materials, EarlyView.
ABSTRACT A key aim in spintronics is to achieve current‐induced magnetization switching via spin‐orbit torques without external magnetic fields. For this, the focus of recent work has been on introducing controlled lateral gradients across ferromagnet/heavy‐metal devices, giving variations in thickness, composition, or interface quality.

Bioinspired Adaptive Surfaces for Intelligent Liquid Manipulation: Progressing From Passive and Active to Hybrid Strategies

Advanced Materials, EarlyView.
This review examines passive, active, and hybrid liquid manipulation strategies, highlighting hybrid approaches as an emerging route to reconcile energy efficiency with adaptive control. By actively reconstructing passive surfaces to store programmable interfacial energy, hybrid systems enable flexible yet low‐power liquid transport, with perspectives ...

The Role of High-frequency Transverse Oscillations in Coronal Heating

The Astrophysical Journal Letters, 2023
Transverse oscillations that do not show significant damping in solar coronal loops are found to be ubiquitous. Recently, the discovery of high-frequency transverse oscillations in small-scale loops has been accelerated by the Extreme Ultraviolet Imager ...

Solar and Solar-Like Oscillations: Theory [PDF]

Highlights of Astronomy, 1986
AbstractSolar five-minute oscillations provide a means of testing theoretical models of the sun. By judiciously combining data from low-degree modes, properties of the central and surface regions of the sun can be inferred separately. In principle, it should be possible to draw similar inferences from other stars, once adequate data are available ...

The n−n¯ oscillations in neutron fluxes running from Sun to Earth

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2011
The process of n−n¯ oscillations in the solar cosmic-rays is considered. It is shown that it has high intensity with respect to the analogic processes on the Earth (Ic−r/IEarth∝108), because magnetic field strongly suppresses n−n¯ oscillations. Energetic
