Iterated stretching, extensional rheology and formation of beads-on-a-string structures in polymer solutions [PDF]
The transient extensional rheology and the dynamics of elastocapillary thinning in aqueous solutions of polyethylene oxide (PEO) are studied with high-speed digital video microscopy.

Defect‐Mediated Inelastic Light Scattering by Infrared Phonons in Hexagonal Boron Nitride
Optically active defects in hexagonal boron nitride enable inelastic stimulated light scattering mediated by infrared‐active phonons, relaxing conventional Raman selection rules. Defect engineering enhances the Stokes‐conversion process and activates both TO‐ and LO‐phonon scattering channels.

Magneto‐Ionic Devices With Polymer‐Based Electrolytes
Polymer electrolytes are introduced for magneto‐ionic devices based on hydroxide and hydrogen ions. The magneto‐ionic effect results in a pronounced voltage‐controlled variation of coercivity in both devices. The switching speed is in the range of 100 ms.

Shear Thickening—Shear Thinning Transitions in Chitosan Hydrogel
Shear-Thickening or dilatant behavior is difficult to observe because it is frequently confused with mechanical oscillation or with experimental deviation. In appropriated shear rate range this behavior can be identified in samples that behave as a pseudo-plastic or Newtonian fluid in large shear rate range, evidencing what is currently called the ...

Effective scraping in a scraped surface heat exchanger: some fluid flow analysis [PDF]
An outline of mathematical models that have been used to understand the behaviour of scraped surface heat exchangers is presented. In particular the problem of the wear of the blades is considered.

For the first time, an extreme‐thick laser‐arc PVD ta‐C (DLC) coating exceeding 100 µm is demonstrated, opening up new possibilities for ultra‐high load bearing capacity. This superhard amorphous carbon architecture combines >50% sp3 bonding, robust adhesion and self‐supporting performance, shielding substrates from plastic flow under extreme contact ...

Intracrystalline Void‐Mediated Toughening of Brittle Crystals in Quail Eggshells
In quail eggshells, the high density and disordered arrangement of intracrystalline voids inhibit lattice cleavage, suppress long‐range crack propagation, and promote deformation twinning and quasi‐plasticity, serving as an essential toughening motif. We show that these voids remain within a narrow subcritical size range and therefore predominantly do ...
