Abstract:
... A horizontal liquid–solid circulating fluidized bed with a transparent single pipe is designed and built to investigate flow characteristics. The effects of the operating parameters, such as the fluid velocity, amount of added particles, particle types and pipe inner diameter on particle distribution and pressure drop in the horizontal test pipe, are systematically investigated by using the image ...

In this paper we introduce a small modular organic liquid scintillator detector array that can detect changes in mass of 238U between 3.69 g and 14.46 g. To do this, 18-h assays of various masses of 0.3% wt. of depleted uranium dioxide were as ...

This study theoretically examines the wetting of a cylindrical cavity engraved on a hydrophobic surface, in the context of the Cassie–Baxter-to-Wenzel transition of a water drop resting on such a surface. The stable, metastable, and transition states and their free energies are identified by constructing the free-energy profile of the wetting process. Wetting starts with a liquid–vapor interface p ...

Abstract:
... When multiple drops impact on a thin liquid film, the interaction dynamic between two impinging drops is prominent. High-speed (>50 m/s) oblique impacts of drops on a liquid film result in asymmetrical splashing patterns and further complicate the phenomenon. To understand the interaction between injected crowns from splashing, numerical simulations are very useful to study the flow behaviors.Thre ...

Abstract:
... Over the past decade, there has been a debate over the correct form of the Cassie–Baxter equation, which describes the expected contact angle of a liquid drop on a heterogeneous surface. The original Cassie–Baxter equation uses an area fraction of each solid phase calculated over the entirety of the surface, and its derivation is based on an assumption not all surfaces necessarily satisfy. Herein, ...

In multivariate curve resolution (MCR) analysis, a range of feasible solutions is often encountered, because of the rotational ambiguities associated with the bilinear decomposition of data matrices. For quantitative purposes, the analysis is usually applied to a carefully designed set of calibration and test samples having uncalibrated interferents. Under the usual minimal constraints (non-negati ...
