A clearer understanding of the dynamic structuring of different natural rubber genotypes on a macroscopic and mesoscopic scale by asymmetrical-flow field-flow fractionation (A4F) analysis

Polymer Testing
Unlike synthetic elastomers, the structure of natural rubber (NR) evolves (dynamic structuring) and so do its properties during the storage before reaching an industrial mixer. In the rubber industry this is known as storage hardening.

Multiscale Structure of Starches Grafted with Hydrophobic Groups: A New Analytical Strategy

Molecules, 2020
Starch, an abundant and low-cost plant-based glucopolymer, has great potential to replace carbon-based polymers in various materials. In order to optimize its functional properties for bioplastics applications chemical groups need to be introduced on the

Influence of Scan Strategies in Electron Beam Powder Bed Fusion on Solidification, Microstructure, and High‐Temperature Compressive Properties of γ′‐Strengthened Inconel 738LC

Advanced Engineering Materials, EarlyView.
Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...

Rapidly Solidified High‐Strength Invar 36 Prepared by Planar‐Flow Melt Spinning

Advanced Engineering Materials, EarlyView.
The Invar 36 alloy was rapidly solidified using the planar‐flow melt‐spinning technique. Ribbon samples with thicknesses ranging from 20 to 160 mm were produced. As the grain size of the ribbon decreased to sub‐micron levels, the hardness increased by more than 2 times.

Investigating the Low‐Temperature Phase Stability of the Binary Ta–W System

Advanced Engineering Materials, EarlyView.
Atomistic simulations show that the binary Ta–W system forms ordered intermetallic phases, B2‐TaW and D03‐TaW3, as 0 K ground states. Configurational entropy, however, lowers the free energy of the disordered bcc solid solution, which becomes the stable phase above about 400 K.

Enhanced Characterization of Lignin Nanoparticles by Asymmetric Flow-Field Flow Fractionation

ChemSusChem
The unique properties of lignin nanoparticles (LNPs)—uniform shape, surface properties and nanoscale—carry great potential for the desired material utilization of technical lignins. Especially, the particle size distribution and dispersity of LNPs are the key for their successful valorization.

CE and asymmetrical flow field flow fractionation studies of polymer interactions with surfaces and solutes reveal conformation changes of polymers [PDF]

, 2020
Amphiphilic diblock copolymers consisting of a hydrophobic core containing a polymerized ionic liquid and an outer shell composed of poly(N-isoprolylacrylamide) were investigated by capillary electrophoresis and asymmetrical flow-field flow fractionation.

Simultaneous Enhancement of Performance and Stability in Dual‐Gate a‐IGZO Thin‐Film Transistors via Single‐Step Laser Annealing for Capacitor‐Less DRAM

Advanced Functional Materials, EarlyView.
A single‐step laser annealing strategy is presented for dual‐gate a‐IGZO TFTs. The steep thermal gradient induces graded oxygen doping in the channel and simultaneous WOx removal at the contacts, enabling concurrent interface and contact engineering.

Tough and Skin‐Free Porous Polyelectrolyte Complex Hydrogels via Salt‐Induced Aqueous Phase Separation

Advanced Functional Materials, EarlyView.
Controlling counterion exchange rate during aqueous phase separation enables the formation of skin‐free, homogeneously porous polyelectrolyte complex hydrogels by suppressing kinetically trapped skin layers and macrovoids. The resulting hydrogel networks exhibit exceptional toughness (∼15 MJ·m−3) and enable 3D (bio)printing and post‐functionalization ...
