Freeform Manufacturing of Plant‐Based Structural Colors for Scalable Photonic and Mechanochromic Devices

open access: yesAdvanced Materials, Volume 38, Issue 35, 23 June 2026.
A green, freeform manufacturing approach that utilizes robust aqueous two‐phase systems to create intricate and scalable photonic structures and non‐planar mechanochromic hydrogel actuators from plant‐based hydroxypropyl cellulose. This approach broadens the structural possibilities of sustainable photonic devices and mechanochromic systems, offering ...

Fluid dynamic treatment of thixotropic debris flows and avalanches [PDF]

open access: yes, 2005
Some forms of mud flows and debris flows exhibit a non-Newtonian thixotropic behaviour, and this study describes a basic study of dam break wave with thixotropic fluid.

Aggregation of Ag6‐Derived Clusters in Dialdehyde Hydroxypropyl Methylcellulose for Fluorescent Security Ink

open access: yesAggregate, Volume 7, Issue 6, June 2026.
Dialdehyde hydroxypropyl methylcellulose acts as a solvent‐responsive polymer microenvironment, promoting Ag6‐derived cluster aggregation after ethanol addition and enabling bright yellow emission under UV excitation. After being formulated into an ink, the aggregation‐regulated system supports screen printing of fluorescent security patterns, latent ...

Thixotropic Hydrogels for Biomedical Applications

open access: yes, 2017
Tetraethyl orthosilicate (TEOS)-based systems are thixotropic (gel-like) under static conditions and solution-like under agitation or sheer. They can be understood as dynamically crosslinked systems that assemble and disassemble via electrostatic ...

Mechanism of thixotropic behavior at relaxed joints in the rat

open access: yes, 1987
When a relaxed joint is subjected to a small sinusoidal torque, the amplitude of the steady-state displacement response is increased up to severalfold by a transient larger perturbation.

Computational Rheo‐Hydrodynamic Analysis of Non‐Newtonian Blood Flow Through a Tilted Ellipsoidal Stenosed Vascular Segment

open access: yesEngineering Reports, Volume 8, Issue 6, June 2026.
Non‐Newtonian blood flow through multiple tilted ellipsoidal stenoses is numerically investigated using the DeKee‐Turcotte‐Papanastasiou model. The results reveal asymmetric velocity fields, elevated wall shear stress, significant pressure drops, and shear‐dependent thermal effects, highlighting the critical hemodynamic risks associated with eccentric ...

Viscoplastic Modeling the Evolving Mechanical Properties of Shotcrete 3D Printing Material

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT In recent years, additive manufacturing in construction (AMC) has gradually influenced the building industry by offering a faster and more efficient way to build with concrete. Unlike traditional methods that rely on molds, AMC deposits material layer by layer through an automated process, enabling new possibilities for custom designs and ...

Numerical simulation of MHD Sakiadis flows of convectively heated thixotropic nanofluids in a porous medium using revised transport laws and Wakif-Buongiorno's model

open access: yesPartial Differential Equations in Applied Mathematics
Due to the particular inability of Fourier's and Fick's laws in the realistic quantification of transfer processes that can occur certainly within a flowing biphasic mixture, on the one hand, and the explanation of the memory relaxation features of such ...

Process Window Optimization for Roll‐to‐Roll Slot‐Die Coating of High‐Resolution Dry Film Solder Resists for HDI PCB Applications

open access: yesPolymer Engineering &Science, Volume 66, Issue 6, Page 4095-4106, June 2026.
A hydrodynamic process window for roll‐to‐roll slot‐die coating of photosensitive solder resist (PSR) was established by systematically varying the slot‐die gap and pump flow rate. Under the optimized conditions, a highly uniform 26 μm dry‐film solder resist (DFSR) layer with a thickness variation of ±3.74% was obtained without coating defects.
