Diffraction of a superfluid Fermi gas by an atomic grating

, 2001
An atomic grating generated by a pulsed standing wave laser field is proposed to manipulate the superfluid state in a quantum degenerate gas of fermionic atoms.

Halide‐Dependent Photoluminescence and Heavy‐Atom Effects in Low‐Melting Organic–Inorganic Manganese Halides

Advanced Functional Materials, EarlyView.
Two pyridinium‐based ionic liquid templated hybrid manganese halides, (C4Py)2[MnCl4] and (C4Py)2[MnBr4], display similar bulk structures but show significantly different photoluminescence behaviors due to the bromine heavy‐atom effect. Their stable local Mn environments remain intact even in the molten state, allowing applications such as luminescence ...

Sensitized Triplet Exciton Generation in Nanostructured Polymer Scintillators: Toward Improved γ/Neutron Discrimination

Advanced Functional Materials, EarlyView.
Rapid γ/neutron discrimination through PSD is achieved in liquid droplet containing nanostructured polymeric scintillator where a TTA‐active dye is dissolved. The inclusion of a properly selected and dosed sensitizer metalated porphyrin enhances discrimination sensitivity and speed by doubling the density of annihilating triplets and increasing the ...

Thermal grating velocimetry

Optics Letters, 1998
A method is reported for time- and space-resolved nonintrusive velocimetry of high-speed gas flows by measurement of the Doppler shift of light scattered from a laser-induced thermal grating. The principle is demonstrated by use of a pulsed frequency-doubled Nd:YAG laser to induce a thermal grating in NO(2) seeded into an argon flow.

Critical Role of Polymer Gate Dielectrics on the Charge Carrier Transport in Perovskite Field‐Effect Transistors

Advanced Functional Materials, EarlyView.
Charge transport in 2D tin perovskite FETs is shown to be governed by dielectric interface behavior. Polar polymer dielectrics induce dipolar disorder that localizes carriers, whereas nonpolar polymers suppress trapping and enable superior charge transport, ensuring stable and reliable transistor operation. ABSTRACT Understanding the role of interfaces

Laser Interferometry for Broad Area SPR-Grating Couplers in Chemical Applications

Proceedings, 2017
In this work, the fabrication of a SPR (Surface Plasmon Resonance)-grating coupler using Laser Interference Lithography (LIL) has been investigated, giving rise to large area diffraction gratings on a 100 nm-thick gold film. The period of the diffraction

3D‐Printed Hygroscopic Polymer Networks for High‐Humidity Triboelectric Nanogenerators to Wirelessly Power Implantable Electronic Devices‐ A Conceptual Pathway

Advanced Functional Materials, EarlyView.
This work develops 3D‐printable tribopolymer networks that can enhance triboelectric performance under high humidity environments. Polar hydrophilic functional groups and incorporation of zwitterionic monomers promote bound‐water–dominated interfacial polarization thereby increasing electrical outputs.
