Quantitative study for control of air–liquid segmented flow in a 3D-printed chip using a vacuum-driven system

open access: yesScientific Reports, 2022
The formation of droplets or bubbles in a microfluidic system is a significant topic requiring device miniaturization and a small volume of samples. Especially, a two-phase segmented flow can be applied to micro-mixing for chemical reactions and the ...

Controllable multichannel acousto-optic modulator and frequency synthesizer enabled by nonlinear MEMS resonator

open access: yesScientific Reports, 2021
Nonlinear physics-based harmonic generators and modulators are critical signal processing technologies for optical and electrical communication. However, most optical modulators lack multi-channel functionality while frequency synthesizers have deficient

Analysis of the DD¯⁎K System with QCD Sum Rules

open access: yesAdvances in High Energy Physics, 2019
In this article, we construct the color singlet-singlet-singlet interpolating current with IJP=3/21- to study the DD¯⁎K system through QCD sum rules approach. In calculations, we consider the contributions of the vacuum condensates up to dimension-16 and

Full Counting Statistics of Electrons through Interaction of the Single Quantum Dot System with the Optical Field

open access: yesNanomaterials, 2019
In this paper, using the particle-number-resolved master equation, the properties of full counting statistics (FCS) are investigated for a single quantum dot (QD) system interacting with optical fields in the thermal state, Fock state, coherent state ...
