Field‐Free, Deterministic Giant Spin‐Orbit Torque Switching of 1.3 T Perpendicular Magnetization With Symmetry‐Lifted Topological Surface States

open access: yesAdvanced Materials, EarlyView.
We show a giant, bias‐field free, deterministic, spin‐orbit‐torque switching of perpendicular hard magnets with HC over 1.3 T. By combining the three‐fold 3m symmetry from topological insulator surface states with the rectangular mm2 symmetry from the 2 x 1 intercalation in Cr3Te4, the interface symmetry is significantly reduced into a unidirectional m

Quantum Optics in Maxwell's Fish Eye Lens with Single Atoms and Photons

open access: yes, 2018
We investigate the quantum optical properties of Maxwell's two-dimensional fish eye lens at the single-photon and single-atom level. We show that such a system mediates effectively infinite-range dipole-dipole interactions between atomic qubits, which ...

Lens of Eye Dosimetry

open access: yes, 2015
An analysis of LANL occupational dose measurements was made with respect to lens of eye dose (LOE), in particular, for plutonium workers. Table 1 shows the reported LOE as a ratio of the “deep” (photon only) and “deep+neutron” dose for routine monitored workers at LANL for the past ten years.

Ultrasound in Women's Health: Mechanisms, Applications, and Emerging Opportunities

open access: yesAdvanced Materials, EarlyView.
As healthcare moves toward decentralization, ultrasound technologies are evolving from strictly imaging tools in clinical settings into versatile diagnostic and therapeutic platforms, with growing roles addressing women's health needs. This review highlights how ultrasound's underlying physical mechanisms can be harnessed to reduce disparities in women'

Dynamic Optical Lattices Through Conducting Polymer‐Gated Confinement

open access: yesAdvanced Materials, EarlyView.
The conducting polymer gate is incorporated into organic dielectric lattices to control the dynamic switching of nonlocal Mie resonances in the visible/NIR regions. The “closed gate” from oxidized PEDOT confines the light within dielectric nanocylinders and activates nonlocal Mie resonances, while the “opened gate” from reduced PEDOT facilitates ...

Comparison of Different Presbyopia Treatments: Refractive Lens Exchange with Multifocal Intraocular Lens Implantation Versus LASIK Monovision [PDF]

open access: yes, 2010
There are several methods for presbyopia treatment. Refractive lens exchange (RLE) followed by multifocal intraocular lens (MFIOL) implantation enables high rate of spectacle independance but have some visual disturbances.

Cr2AlC: A High‐Temperature Transparent Conducting Ceramic

open access: yesAdvanced Materials Interfaces, EarlyView.
The high‐quality epitaxial Cr2AlC(0001) layer combines a low resistivity of 42.5 µΩcm, 84% optical transmittance at 900 nm, and thermal stability up to 800–1100°C. It stands out as an excellent high‐temperature transparent conductor with a negligible resistivity size effect, exceptional scaling (ρoλ < 3 × 10−16 Ωm2), and a figure of merit of 0.004 Ω−1.

Flexible, Integrated‐Porous Microneedle Sensor for Biofluid Sampling and On‐Site Biomarker Detection

open access: yesAdvanced Materials Technologies, EarlyView.
A paper‐integrated porous PGA microneedle array patch capable of both high strength and absorption capacity is proposed. With an image‐processing system, an optimized colorimetric sensor achieves a low limit of detection of 0.09 mm in cholesterol.

Fabrication Technologies for Soft, Multimaterial Optical Fibers for In Vivo Diagnostics and Phototherapy, With a Focus on Extrusion Printing

open access: yesAdvanced Materials Technologies, EarlyView.
Soft multimaterial optical fibers integrate multiple functionalities—such as waveguiding, side emission, sensing, drug delivery or actuation—into a single filament for wearable, implantable, and tissue‐integrated devices for diagnostics and phototherapy.

Enhanced Self‐Phase Modulation in Silicon Nitride Waveguides Integrated With 2D MoS2 Films

open access: yesAdvanced Materials Technologies, EarlyView.
ABSTRACT On‐chip integration of 2D materials provides a promising route toward next‐generation integrated optical devices with performance beyond existing limits. Here, significantly enhanced spectral broadening induced by self‐phase modulation (SPM) is experimentally demonstrated in silicon nitride (Si3N4) waveguides integrated with 2D monolayer ...
