Comparison of Different Electrochemical Setups for Noninvasive Impedance Measurements on Archeological Coins

The electrochemical characterization of cultural heritage objects requires noninvasive approaches. In the case of patina‐covered bronze objects, two essential features of the setups recently proposed to satisfy this requirement are (i) the use of gel electrolytes and (ii) the abs...

Optimizing LaNiO3 Perovskite as Catalyst Precursor for the Revalorization of Biogas by Dry Reforming of Methane

The Dry Reforming of Methane (DRM) is an efficient route to produce syngas (which is the feedstock for the production of synthetic fuels via the Fischer–Tropsch process) or hydrogen from methane and carbon dioxide. This work evaluates several nickel-based perovskite-type mixed ox...

Synergic Improvement of Elastocaloric Effect in Polycrystalline NiMnGaCo by Magneto-Mechanical Coupling

Among the ferromagnetic shape memory alloys (SMAs), Ni43Mn31Ga19Co7 (at%) alloys are well known as a promising ferromagnetic SMA (FeSMA) for magnetocaloric effect, and scientific interest has increased due to the possible exploitation of multicaloric function. This first example...

Characterization of Anisotropic Optical Behavior in Phase‐Change Material Sb 2 Se 3

ABSTRACT Phase‐change materials with ultralow optical losses are enabling a new generation of reconfigurable photonic devices. Sb 2 Se 3 has emerged as a leading candidate owing to its negligible optical losses across the visible and infrared, yet how polycrystallinity translates...

Mixed Multilayersof Protein Fibrils with Sodium orCalcium Alginates

Abstract A layer-by-layer approach is used for the preparation of multilayer films on the basis of biomacromolecules and their aggregates, protein fibrils. In this work, the fibrils were prepared from β-lactoglobulin and oat globulin, while sodium and calcium alginates were used...
