Aramid Nanofiber Aerogels: Preparation, Modification, Composite Fabrication, and Applications

open access: yesAdvanced Materials, EarlyView.
Different forms of aramid nanofibers (ANFs) and especially aerogels from them, offer a sustainable route to high‐performance biomimetic nanocomposites. Due to the cartilage‐like architecture, ANF‐based materials enable breakthroughs in energy, electromagnetic, biomedical, and water purification technologies.

On the Flow of Generalized Burgers' Fluid Induced by Sawtooth Pulses

open access: yesJournal of Applied Fluid Mechanics, 2015
This paper presents a study for the MHD flow of an incompressible generalized Burgers' fluid through a rectangular duct in porous medium. The flow is generated due to the velocity sawtooth pulses applied on the duct.

Multi‐Agent‐Network‐Based Idea Generator for Zinc‐Ion Battery Electrolyte Discovery: A Case Study on Zinc Tetrafluoroborate Hydrate‐Based Deep Eutectic Electrolytes

open access: yesAdvanced Materials, EarlyView.
An LLM‐based multi‐agent network screens academic literature to propose multiple environmentally friendly aqueous deep eutectic electrolytes for zinc‐ion batteries. Experiments identify an optimal composition of Zn(BF4)2·xH2O and ethylene carbonate, which shows high conductivity and cycling stability.

Standalone Integrated Magnonic Devices

open access: yesAdvanced Materials, EarlyView.
A standalone (not requiring external bias magnetic field) and tunable magnonic device is reported with all‐electric input and output, fully integrated on silicon (total footprint of 100 × 150 µm) and 3–8 GHz frequency band. This is achieved by monolithic integration of a CoFeB conduit with RF antennas and an assembly of NiFe and SmCo micromagnets ...

A Coinfection Model of Leptospirosis and Melioidosis With Optimal Control

open access: yesJournal of Applied Mathematics
Leptospirosis and melioidosis are emerging tropical diseases that are seriously affecting both human and animal populations worldwide. The actual incidence and fatal cases of the diseases are underreported due to a lack of awareness of the diseases ...

Programming Defects and Cavities into Colloidal Crystals Engineered With DNA

open access: yesAdvanced Materials, EarlyView.
Seed‐mediated crystallization is adapted for colloidal crystals to design cavities and defect architectures through chemically programmed DNA sequences and appropriate seed particle geometry. This synthetic approach combines tenets from both atomic and colloidal crystallization to deliberately control defect formation in superlattices and enables the ...

Some existence results for a class of Dirichlet problems with variable exponents

open access: yesBoundary Value Problems
In this paper, we study the existence and multiplicity of weak solutions of the p ( x ) $p(x)$ -Laplacian problems that are subject to Dirichlet boundary conditions, employing variational techniques as our primary analytical framework.
