Deformation‐Tolerant Functional Elastomer Overlayers for Haze‐Assisted Light Extraction and Color Conversion in Stretchable Mechanoluminescent Films

open access: yesAdvanced Functional Materials, EarlyView.
Functional elastomer overlayers are integrated onto stretchable ZnS:Cu‐PDMS mechanoluminescent films to regulate light after emission without modifying the emissive composite. NLC‐PU provides haze‐assisted light extraction to enhance green mechanoluminescence, while DCM‐NLC‐PU combines green‐to‐yellow‐orange color conversion with enhanced outward light

Optical anisotropy and strain evolution of GaAs surfaces at the onset of the formation of InAs quantum dots

open access: yes, 2006
By using reflectance difference spectroscopy we have studied the in-plane optical anisotropy of GaAs surfaces covered by ultrathin InAs layers. The strain evolution of the GaAs surface with the InAs deposition thickness can be obtained.

Carrier-controlled reconfigurable mid-IR hyperbolicity in ZnO via phonon–plasmon coupling

open access: yesJPhys Photonics
Natural hyperbolic materials are attractive materials for mid-infrared nanophotonics but typically offer fixed and narrow hyperbolic bands set by optical phonons.

Molecular Bridges for 2D Nanomaterials

open access: yesAdvanced Functional Materials, EarlyView.
Molecular cross‐linking provides a versatile strategy to engineer interfaces in 2D materials. By tuning the linker backbone, binding mode, and interflake spacing, molecular bridges can regulate charge transport, mechanical integrity, chemical functionality, and processing.

A Nonlinear Organic Low‐Frequency Sound Sensor Based on Electrochemical Coupling in a Solidified Gel Membrane

open access: yesAdvanced Functional Materials, EarlyView.
A novel nonlinear infrasound sensor concept based on a free‐standing ion conductive gel membrane is introduced. Acoustic signals are directly transduced into an electrical signal using an internal application mechanisms (gating). The nonlinearity might be used for neuromorphic in‐sensor computing. ABSTRACT Measuring low‐frequency or infrasound acoustic

An optical study of dislocation-induced anisotropy in alkali halide single crystals

open access: yes, 1967
A series of investigations was carried out on four KCl single crystals and LiF single crystal to determine how the observed optical anisotropy of the samples was related to the magnetic anisotropy of alkali halide crystals detected by other experimenters.

Seismic anisotropy in siliciclastic reservoir rocks [PDF]

open access: yes, 2006
The interpretation of geophysical field measurements of seismic anisotropy is presently limited by our knowledge of the controls of the elastic anisotropy of sedimentary rocks in the subsurface. Traditionally, laboratory ultrasonic velocity measurements

Efficient Magnetization Switching Driven by Orbital Torque in Light 3d Transition‐Metal Nitrides

open access: yesAdvanced Functional Materials, EarlyView.
Efficient magnetization switching is demonstrated through orbital torque generated from light 3d transition‐metal nitride. Transition‐metal nitrides are established as effective sources of orbital angular momentum for current‐induced switching, highlighting their potential for low‐power next‐generation orbitronic devices beyond conventional heavy‐metal‐

Methods and means of polarization-interference layer reconstruction and discrete phase scanning of jones matrix images of polycrystalline films of dehydrated bile

open access: yesБіофізичний вісник
Background: Modern methods of Mueller matrix polarimetry are aimed at determining the criteria and practical application of such markers in the differential diagnosis of pathological and necrotic changes in biological tissues of human organs. At the same

Orbital Engineering through Strain‐Induced Spin–Orbit–Lattice Coupling in Sr2FeReO6 Double Perovskites

open access: yesAdvanced Functional Materials, EarlyView.
Epitaxial strain drives oxygen‐octahedral reconfiguration in Sr2FeReO6 double‐perovskite thin films, inducing orbital‐selective reconstruction of Re 5d states through modified Fe–O–Re hybridization. This coupled lattice–orbital response enables magnetic easy‐axis reversal and a transition from metallic‐like to semiconducting‐like transport.
