Shear‐Induced Anisotropic Supramolecular Gel Noodles for Improved Cell Guidance in Polarized Tissue Engineering

Small, EarlyView.
A simple two‐stage extrusion aligns supramolecular fibrils into 1D gel noodles. The residual pressure in the viscous pre‐gel drives the formation of a thin filament that is locked by Ca2+ cross‐linker into a highly anisotropic segment. The aligned noodles show enhanced tensile strength and guide myoblast elongation along the fiber, mimicking aligned ...

Record‐Low Compressibility in [N(C2H5)3CH3]FeCl4 Expands Phase Engineering Horizons in Hybrid Molecular Ferroelectrics

Small, EarlyView.
High‐pressure studies of the lead‐free hybrid organic–inorganic ferroelectric [N(C2H5)3CH3]FeCl4 demonstrate record low compressibility, establishing it as the least compressible molecular ferroelectric known. In situ diamond anvil cell experiments identify halide selection and inorganic sublattice tuning as key compressibility controls, advancing ...

Mapping the Residual Stress Distribution in Polycrystalline Quartz Tiger's Eye Using Raman Spectroscopy

Small Methods, EarlyView.
Residual stresses in Tiger’s Eye quartz have been mapped by combining Raman spectroscopy and electron back scatter diffraction. The study quantified stress distributions likely formed during cooling due to the anisotropy of thermal contraction. This non‐destructive methodology provides a reliable baseline for mapping stress in both natural polycrystals

Additive Manufacturing of Hot‐Work Tool Steel by In Situ Alloying Using Laser Powder Bed Fusion and Directed Energy Deposition—Strategies to Improve Chemical Homogeneity

steel research international, EarlyView.
To support future alloy development a powder mixture is processed by laser additive manufacturing. The powder mixture containing Mo‐ and W‐rich tracers is processed by powder bed fusion using single and double laser exposure and by directed energy deposition which provides drastically enlarged melt pools.

In Situ Alloying of H13 Tool Steel With TiC via PBF‐LB/M

steel research international, EarlyView.
H13 tool steel is in situ alloyed with titanium carbides (TiC) in amounts up to 30 wt.%. This approach offers the advantage that the carbides melt only partially during processing, preventing excessive carbon enrichment of the steel matrix. The resulting microstructure consists of coarse, undissolved and fine, reprecipitated carbides, leading to grain ...

Exploring poly‐L‐lysine‐based particle capture for atomic force microscopy studies of extracellular vesicles

Journal of Microscopy, EarlyView.
Abstract We herein investigate the effects of varying the main experimental variables in one of the most used protocols for extracellular vesicle (EV) immobilisation on substrates for subsequent atomic force microscopy (AFM) quantitative morphometry and nanoindentation performed in liquid. We introduce the parameter Q as a quantitative measure of total
