Investigation of the Mechanical Behaviors of Waterborne Polyurethane: The Critical Influence of Hard Segment Content Over Various Strain Rates

Macromolecular Materials and Engineering, Volume 310, Issue 9, September 2025.
This study explores how hard segment content (HS) modulates waterborne polyureathane's (WPU's) dynamic mechanical properties under low/high strain rates. Increasing HS enhances hydrogen bonding and microphase separation, with abundant hard domains acting as physical crosslinks.

Speed of propagation for Hamilton-Jacobi equations with multiplicative rough time dependence and convex Hamiltonians

, 2019
We show that the initial value problem for Hamilton-Jacobi equations with multiplicative rough time dependence, typically stochastic, and convex Hamiltonians satisfies finite speed of propagation.

Performance of spiral-shaped steel fibre reinforced concrete structure under static and dynamic loads [PDF]

, 2015
Concrete is the most widely used construction material due to its impressive resistance to compressive load. The major weaknesses of concrete are its brittleness and poor resistance to tensile forces. Intensive number of studies has been conducted to add

Highly Oriented Bio‐Mimetic Hydrogels by Calendering

Advanced Science, Volume 12, Issue 30, August 14, 2025.
A facile and scalable organogel‐assisted calendering strategy is proposed to prepare bio‐mimetic anisotropic polyvinyl alcohol (PVA) hydrogels. By employing a combination of shearing and annealing during calendering, PVA chains are aligned in the calendering direction, while the compression in thickness facilitates the formation of a nacre‐like ...

Study on Energy Evolution Law of Rocks With Different Lithologies and Sizes

Energy Science &Engineering, Volume 13, Issue 8, Page 4199-4210, August 2025.
ABSTRACT Investigating the actual patterns of energy accumulation and release in roof rock, particularly with varying stiffnesses in mining environments, is crucial. By conducting cyclic loading and unloading tests on rock samples of different lithologies, different sizes, and consistent stiffness, how lithology, size, and stiffness affect the ...

Elongational Viscosity Measurements Using a Semi-Hyperbolic Die

Applied Rheology, 2006
The lubricated semi-hyperbolic die has been proposed as a technique for generating uni-axial extensional flow and, hence, as a device for measuring elongational viscosity. Two methods for extracting extensional viscosity data for polymer melts in laminar
