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,

Conversion between dipoles with different spatial parities by circularly polarized light

Materials Today Quantum
We investigate the effect of a circularly polarized light on multipoles based on the Floquet formalism. We show that the irradiation of the circularly polarized light converts the spatial parity of dipoles at the microscopic level; the electric (magnetic

Strain effect on circularly polarized electroluminescence in transition metal dichalcogenides

Physical Review Research, 2020
Strain effect on circularly polarized electroluminescence (EL) is theoretically analyzed for a p-i-n junction of transition metal dichalcogenides. The electrically controllable circularly polarized EL without the strain effect is understood by valley ...

Dual Circularly Polarized Reflectarray With Independent Control of Polarizations [PDF]

IEEE Transactions on Antennas and Propagation, 2015
A reflectarray with independent dual-circular polarizations is proposed for the first time. The reflector panel operates in X-band and contains 97 unit-cells. It is made with a lego-type configuration allowing change manually the phase aperture distribution and demonstrating experimentally the independence of both polarizations in the same frequency ...

Three‐dimensional Antimony Sulfide Based Flat Optics

Advanced Functional Materials, EarlyView.
This work presents the development of a grayscale electron beam lithography (g‐EBL) method for fabricating antimony trisulfide (Sb2S3) nanostructures with customizable 3D profiles. The refractive index of g‐EBL patterned Sb2S3 is determined based on the synergy of genetic algorithm and transfer matrix method.

Melt Grafting of Geometry‐Tailored Voltage Stabilizers for High‐Performance Polypropylene Insulation

Advanced Functional Materials, EarlyView.
A scalable one‐step melt grafting strategy is developed to enhance the dielectric properties of isotactic polypropylene by covalently incorporating thermally stable aromatic voltage stabilizers. This solvent‐free approach improves volume resistivity and DC breakdown strength through deep trap formation and charge localization, offering a sustainable ...

Circularly polarized luminescence with high dissymmetry factors for achiral organic molecules in solutions

Nature Communications
Circularly polarized luminescence (CPL) in solution offers several advantages. However, it remains challenging for organic molecules to achieve circularly polarized luminescence with high dissymmetry factor (g lum) in solution. Herein, a general strategy

Phonon-driven spin-Floquet magneto-valleytronics in MoS2

Nature Communications, 2018
In 2H semiconducting transition-metal dichalcogenides the valley-selective excitation has been achieved with circularly polarized photons. Here, the authors show that circularly polarized phonons produce a valley-dependent dynamic spin state as a result ...

Centimeter Polarimetry of the R Coronae Australis Region

, 2008
Circularly polarized 3.5 cm continuum emission was detected toward three radio sources in the R CrA region using the Very Large Array. The Class I protostar IRS 5b persistently showed polarized radio emission with a constant helicity over 8 yr, which ...

Germanane Quantum Dots Promote Metabolic Reprogramming of Immune Cells Toward Regulatory T Cells and Suppress Inflammation In Vitro and In Vivo

Advanced Functional Materials, EarlyView.
Metabolic changes in immune cells direct the phenotype and function of the host immune system. Smart nanomaterials must target metabolic pathways to direct immune cell fate. This study reports the fabrication and first application of germanane quantum dots (GeHQDs) to modulate inflammation in vitro and in vivo.
