Advances in Floating Solar Desalination Systems

open access: yesWater and Environment Journal, EarlyView.
This review critically classifies floating solar desalination systems into five main categories and compares their thermal performance, productivity and technological limitations. Membrane‐based and multieffect systems showed the highest efficiencies, while traditional designs remain limited by heat losses and scaling.

The Role of Mafic Intrusion in Seismotectonics: Insights From the 1668 M 8.5 Tancheng Earthquake Rupture Zone Along the Tan‐Lu Fault Zone, Eastern China

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The Tan‐Lu Fault Zone (TLFZ), the largest lithosphere‐scale strike‐slip fault in eastern China, has experienced multiple tectonic stages and remains high seismic activity, including the 1668 Tancheng earthquake (M 8.5). Here we employ dense‐array receiver functions to resolve crustal thickness, Vp/Vs ratio, and seismic discontinuities in the ...

Current‐Driven Nonreciprocal Response of Nonequilibrium Skyrmions

open access: yesAdvanced Science, Volume 13, Issue 31, 4 June 2026.
A skyrmion holds great promise for spintronic applications owing to its intrinsic topological stability and high mobility under ultra‐low current excitation. Here, by means of in situ electron microscopy, we demonstrate a skyrmion diode effect and the associated current‐driven nonreciprocal skyrmion dynamics in a designed FeGe‐based microdevice.

Metallic Fresnel zone plate implemented on an optical fiber facet for super-variable focusing of light.

open access: yesOptics Express, 2017
We propose and investigate a metallic Fresnel zone plate (FZP/MFZP) implemented on a silver-coated optical fiber facet for super-variable focusing of light, the focal point of which can be drastically relocated by varying the wavelength of the incident ...

Imaging and Linking Spatial Magnetic Nanoparticle Distribution to Microbead Torques Using Soft X‐Ray Laminography

open access: yesAdvanced Physics Research, Volume 5, Issue 6, June 2026.
Nanoscale 3D imaging of superparamagnetic microbeads via soft X‐ray laminography reveals the structural origin of the observed torques in cell movement experiments. These microbeads are found to have an uneven distribution of magnetic magnetite nanoparticles.

First Direct Observations of Internal Flow Structures in a Powder Snow Avalanche: Turbulence, Instability and Particle Distribution

open access: yesJournal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract Powder snow avalanches are highly dynamic, multiphase gravity‐driven flows typically composed of a dense basal layer overlain by airborne layers in which snow particles are suspended within a turbulent air phase. Despite extensive work on related systems such as pyroclastic density currents and turbidity currents, all gravity current studies ...

Intracellular Reactive Oxygen Species Generation Induced by High‐Frequency Ultrasound in Thickness Vibration Mode

open access: yesAdvanced Science, Volume 13, Issue 28, 18 May 2026.
Cell‐sized high‐frequency ultrasound using a lithium niobate transducer, previously ignored in reactive oxygen species (ROS) production, generated intracellular ROS at frequencies higher than conventionally used. The intracellular generation of ROS by cell‐sized high‐frequency ultrasound revealed in this study is expected to be applied to innovative ...

Multiple-wave radial shearing interferometer based on a Fresnel zone plate.

open access: yesOptics Express, 2018
A compact multiple-wave radial shearing interferometer (MWRSI) with strong adaptability, which is based on a Fresnel zone plate (FZP), is proposed. The nominally plane beam under test passes through the FZP and diffracts into multiple orders, including ...

Nonlinear fresnel zone plate reflector [PDF]

open access: yes2016 IEEE International Symposium on Antennas and Propagation (APSURSI), 2016
This paper describes a nonlinear Fresnel zone plate reflector designed to operate at 2.8GHz. The alternating Fresnel zones of the reflector are made from two different nonlinear metamaterials: one that reflects like a short circuit at low incident power levels and another that reflects like an open circuit.
