Adjustment of Coatings Morphology and Particle Distribution of Layered Silicates by Freeze‐Drying for Improved Gas Barriers

open access: yesAdvanced Engineering Materials, EarlyView.
Freeze‐drying of layered silicate is the key to get coatings with superior gas barrier. Freeze‐drying of layered silicates modified with dodecylamine (DDA) is a highly effective technique for the preparation of barrier pigments that significantly mitigate the permeation of oxygen, water vapor, and hydrogen through polymer films containing these ...

Mesoscopic lattice Boltzmann modeling of soft-glassy systems: theory and simulations

open access: yes, 2009
A multi-component lattice Boltzmann model recently introduced (R. Benzi et al. Phys. Rev. Lett 102, 026002 (2009)) to describe some dynamical behaviors of soft-flowing materials is theoretically analyzed.

On the Impact Energy Absorption of an Advanced High‐Strength Bilayer Steel Composite Consisting of Carbide‐Free Bainitic Steel and High‐Mn Twinning‐Induced Plasticity Steel

open access: yesAdvanced Engineering Materials, EarlyView.
Excellent combinations of strength and impact toughness are obtained in a bilayer composite of high‐strength carbide‐free bainitic (CFB) steel and high‐ductility twinning‐induced plasticity (TWIP) steel. The composite absorbs energy at small strains when the notch is placed on the TWIP side and at high strains when the notch is placed on the CFB side ...

Polymer-tethered pyridine tunes activities of the two distinct CO2 electroreduction sites on Cu

open access: yesNature Communications
CO2 electroreduction (CO2RR) to multi-carbon products on Cu was found to occur via a two-site mode: one site is more active for CO2-to-CO conversion, and the other is primarily responsible for CO reduction.

Hierarchical self-assembly of organic heterostructure nanowires

open access: yesNature Communications, 2019
Organic heterostructures attract attention in material chemistry but the precise bottom-up synthesis is still challenging. Herein the authors present a hierarchical self-assembly approach to synthesize one-dimensional organic heterostructures by ...

Rheological hysteresis in soft glassy materials

open access: yes, 2012
The nonlinear rheology of a soft glassy material is captured by its constitutive relation, shear stress vs shear rate, which is most generally obtained by sweeping up or down the shear rate over a finite temporal window.

Soft Material Characterisation

open access: yes, 2023
A uniaxial tensile test on an Instron Universal Tester 3345 (Instron, MA) was used to investigate the various TPU. material properties and the bonding strength between different TPUs. Following ASTM 412 (Standard Test Methods For Vulcanized Rubber And Thermoplastic Elastomers) guidelines, we prepared dogbone samples following the type C die.
