We report an experimental study on the two dimensional flow focusing enabled by a wedge over a slit that provides similar gas flow restriction. As the wedge-to-slit distance is gradually reduced, the liquid dripping transforms into a single continuous jet that then splits into two, three, and...
we improve >2-fold spatially and >10-fold temporally the resolution of planar cellular force probing compared to its related conventional modalities by combining fast two-dimensional total internal reflection fluorescence super-resolution structured illumination microscopy and traction force microscopy. This ...
高速摄像机多相流体动力学是能源、动力、核反应堆、化工、石油、制冷、低温、可再生能源开发利用、航空航天、环境保护、生命科学、等多领域实现现代化的重要理论和关键技术基础。多相流中气液两相流动最为复杂,它能进一步揭示两相流动一些基本规律,深入研究流动与传热的特性,进而推动两相流的发展和研究,所以气液两相流...
liquid–liquid two-phase flowWhen two-phase flow enters the microscale, its flow and heat–mass transfer characteristics change significantly compared to conventional scales. Existing two-phase flow–heat transfer experiments at conventional scales cannot adequately demonstrate unique physical phenomena at ...
Formation mechanisms of two-dimensional nanostructures in wet syntheses are poorly understood. Even more enigmatic is the influence of hydrodynamic forces. Here we use liquid flow cell transmission electron microscopy to show that layered double hydroxid
A three-dimensional (3D) computational fluid dynamics (CFD) simulation of liquid–liquid two-phase flow is performed on a pilot-plant scale annular pulsed disc and doughnut column (APDDC). Two-fluid Euler–Euler method augmented with k-ε model is used. The two-phase hydraulic performance are...
Using the inner mitochondrial membrane subproteome as a model proteome, we compared for the first time the ability of three protein separation methods (two-dimensional liquid chromatography using the ProteomeLab™ PF 2D Protein Fractionation System from Beckman Coulter, one-dimensional reversed phase ...

To gain a better insight in the sample composition, liquid chromatography (LC) and (comprehensive) two-dimensional liquid chromatography (2D-LC or LC × LC) can be coupled to the MS. Low-flow separations are attractive for HRMS analysis, but they tend to be lengthy. In this work, a low...
This paper presents a neural network based approach that has been applied to Coriolis flowmeters to measure both the liquid flow rate and the gas volume fraction of a two-phase flow. Experimental tests were conducted on a purpose-built two-phase flow test rig on both horizontal and vertical ...
