The Gas‐Liquid Separation Characteristics Inside a Drainage Self‐Priming Pump Under Different Discharge Valve Openings

open access: yesEnergy Science &Engineering, EarlyView.
To investigate the influence of discharge valve opening on the self‐priming characteristics of a self‐priming pump, numerical calculations are conducted for four different discharge valve openings based on a circulation piping system. The hydraulic performance and the internal flow characteristics during self‐priming process are obtained.

Degenerate two-phase incompressible flow problems III: Perturbation analysis and numerical experiments

open access: yesElectronic Journal of Differential Equations, 1999
This is the third paper of a three-part series where we develop and analyze a finite element approximation for a degenerate elliptic-parabolic partial differential system which describes the flow of two incompressible, immiscible fluids in porous media ...

Trash‐to‐Energy: Shedding Light on Plastic and Biomass Valorization Through Artificial Photosynthesis Towards Sustainability

open access: yesExploration, EarlyView.
To engrave a circular economy, artificial photosynthesis emerges as a promising and prosperous strategy to upcycle solid waste into clean fuel and valuable chemicals for sustainable fuel production. This review highlights the design of photocatalysts and external‐field‐assisted photocatalysis for effective solid waste conversion toward an ...

Existence and regularity of a global attractor for doubly nonlinear parabolic equations

open access: yesElectronic Journal of Differential Equations, 2002
In this paper we consider a doubly nonlinear parabolic partial differential equation $$ frac{partial eta (u)}{partial t}-Delta _{p}u+f(x,t,u)=0 quad hbox{in }Omega imesmathbb{R}^{+}, $$ with Dirichlet boundary condition and initial data given.

Strain analysis of black‐to‐yellow phase transitions in CsPbI3

open access: yesInfoMat, EarlyView.
All‐inorganic metal‐halide perovskite CsPbI3 shows strong potential for photovoltaic applications. Here strain analysis is used to probe the mechanisms behind the instability of its photoactive black phase. The results indicate that a relatively large positive (e1–e2) strain is the primary driver of the black‐to‐yellow phase transition.

Perovskite‐based time‐domain signal‐balancing LiDAR sensor with centimeter depth resolution

open access: yesInfoMat, EarlyView.
In this study, we present a monolithic high‐speed perovskite‐based photodetector capable of directly sensing the time delay between two light pulses with a temporal resolution of at least 170 ps. This outstanding time resolution is achieved through a signal‐balancing detection scheme that effectively overcomes the limitations of conventional ...
