In situ shrinkage measurement of holographic polymer dispersed liquid crystals
TL;DR: In this article, a modified diffusion model is proposed to describe the time dependent shrinkage of the polymer matrix during formation and the relationship between polymer shrinkage and functionality in H-PDLC systems is found to be linear.

PdAu and PdAuAg composite membranes for hydrogen separation from synthetic water-gas shift streams containing hydrogen sulfide
TL;DR: Electroless deposition was used to fabricate Pd–23Au and Pd-20Au–13Ag membranes on Pall AccuSep ® ZROD supports that had higher single-gas H 2 permeability than a pure Pd membrane on a comparable support and sulfides were not detected using XRD.

Oxidation behaviour of silicon-free tungsten alloys for use as the first wall material
TL;DR: The use of self-passivating tungsten alloys as armour material of the first wall of a fusion power reactor may be advantageous concerning safety issues as discussed by the authors, however, the formation of brittle tengsten silicides may be disadvantageous for the powder metallurgical production of bulk W?Cr?Si alloys if a good workability is needed.
