Complex Pt/Al2O3 materials for small catalytic systems [PDF]
, 2007 This paper reports on the preparation of catalytic materials composed of a porous metallic preform containing winding microchannels whose surface is coated by a complex catalytic film. Al2O3 is deposited inside the pores by means of wet impregnation in a

A Systematic Comparison of Alpha‐Synuclein Seed Amplification Assays for Increasing Reproducibility
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Seed amplification assays (SAAs) enable ultrasensitive detection of misfolded α‐synuclein across biofluids and tissues. Yet, heterogeneity in protocols limits cross‐study comparability and clinical translation. Here, we review α‐synuclein SAA methods and their performance across various biological matrices.

Advanced Engineering Materials, EarlyView.A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

Preform designing approach in cold orbital forging of flange gear
Advances in Mechanical Engineering, 2018 Flange gear has a complex geometry and its volume distribution along the axial direction changes suddenly. This makes it difficult to be formed by a single step using a simple cylinder workpiece and the preform is necessary.
