EVSS‐Based Simulation Techniques for the Viscoelastic Fluids With Pure Polymer Melts Using Three‐Field Approach

International Journal for Numerical Methods in Fluids, EarlyView.
This paper presents a finite element method for simulating highly viscoelastic flows of pure polymer melts using the Elastic Viscous Stress Splitting formulation. The method avoids higher‐order derivatives in the weak formulation by reformulating the convective term in the constitutive equation.

Polymer Stress‐Tensor Calculation for a Laminar Submerged Viscoelastic Jet Flow Using Different Constitutive Models

International Journal for Numerical Methods in Fluids, EarlyView.
This study presents an efficient method to compute polymer stress‐tensor components in viscoelastic laminar jet flows using models such as Oldroyd‐B, Giesekus, PTT, and FENE. By assuming a stationary and parallel flow, the methodology significantly reduces computational cost.

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

InfoMat, 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

InfoMat, 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 ...
