Stopping a Multilayered Co‐Axial Flow in a 3D Printed Microchannel with Cascaded Nozzles

Advanced Materials Technologies, EarlyView.
A microfluidic device with cascaded nozzles is 3D‐printed using two‐photon polymerization. Its microchannel, featuring integrated nozzles, sculpts multilayered co‐axial flows, enabling independent regulation of four co‐flowing streams to achieve variable layer thicknesses.

The mathematics of suspensions: Kac walks and asymptotic analyticity

Electronic Journal of Differential Equations, 2000
Of concern are suspension flows. These combine directed and random motions and are typically modelled by parabolic partial differential equations.

Understanding the Optoelectronic Processes in Colloidal 2D Multi‐Layered MAPbBr3 Perovskite Nanosheets: Funneling, Recombination and Self‐Trapped Excitons

Advanced Optical Materials, EarlyView.
Mechanisms by which excitons and charge carriers can funnel and recombine in 2D multi‐layered MAPbBr3 Ruddlesden‐Popper perovskite nanosheets are missing. This femtosecond transient absorption spectroscopy study creates a comprehensive understanding of how directed transport, exciton‐exciton annihilation, and Auger recombination occur in colloidal ...

Plasmonic and Photonic Modes in Colloidal CuS Nanocrystals

Advanced Optical Materials, EarlyView.
Copper sulfide in the covellite phase (CuS) can exhibit exceptional optoelectronic properties with plasmonic and photonic absorption in its monolithic nanomaterial form. In this work, the phenomenon of near‐infrared (NIR) to visible electromagnetic field localization in ultrathin crystalline quasi‐2D CuS nanocrystals is demonstrated by mapping ...

Origin of the Laser‐Induced Picosecond Spin Current Across Magnetization Compensation in Ferrimagnetic GdCo

Advanced Optical Materials, EarlyView.
Picosecond spin current pulses generated by ferrimagnetic GdCo are studied via THz emission spectroscopy. Due to the GdCo micromagnetic structure, the spin current vanishes at compensation when a magnetic field is applied but persists for zero field. At room temperature, the THz spin current is dominated by Co. At low temperatures, Gd can significantly

Spatially Controlled Optical Vortex Generation Using Low‐Loss Antimony Telluride Metasurfaces

Advanced Photonics Research, EarlyView.
The spatially varying vortex beams with the customizable propagation trajectory and the controllable topological charge evolution are demonstrated using the Sb2Te3‐based plasmonic metasurfaces. Benefiting from the dispersion‐free property of the Pancharatnam–Berry phase and the broadband response of polarization conversion efficiency of the nanobrick ...

Microwave Monitoring by Compact Carbon Nanotube Photo‐Thermoelectric Sensors Beyond the Diffraction Limit Toward Ultrabroadband Non‐Destructive Inspections

Advanced Sensor Research, EarlyView.
This work overcomes long‐standing crucial technical difficulties in miniaturizing micro‐wave detectors, caused by the longer‐wavelength diffraction limit, with carbon nanotube (CNT) film photo‐thermoelectric sensors. The CNT film sensor exhibits sensitive micro‐wave detection operations with signal‐to‐noise ratios over 1400 at compact device sizes ...

A Theoretical Investigation on Coupled Mass‐charge Transport in a Binary Fluid

Advanced Theory and Simulations, EarlyView.
This study presents a theoretical framework for coupled mass‐charge transport in binary fluids using molecular dynamics simulations. By deriving governing equations from conservation laws and Onsager's theory, the approach introduces generalized diffusivity and electrostatic friction terms.
