Comparison of yttrium and chromic oxides as inert dietary markers for the estimation of apparent digestibility coefficients in mirror carp Cyprinus carpio fed on diets containing soybean‐, maize‐ and fish‐derived proteins

open access: yes, 2006
The apparent digestibility coefficients (ADC) of protein, lipid and energy components within three selected plant protein by-products, i.e. solvent-extract soybean meal, full-fat soybean meal and maize gluten meal were evaluated for mirror carp (Cyprinus

Hot-pressed silicon nitride with various lanthanide oxides as sintering additives [PDF]

open access: yes
The effects of addition of various lanthanide oxides and their mixture with Y2O3 on the sintering of Si3N4 were investigated. The addition of simple and mixed lanthanide oxides promoted the densification of Si3N4 in hot-pressing at 1800 C under 300-400kg/

On the identification of Ti-Ta-Nb-oxides in “wiikites” from Karelia [PDF]

open access: yes, 2018
Purpose. With respect to the nature of Ti-Ta-Nb-oxides, which are included in the mineral associations that have historically gone by the now outdated name of “wiikites”, there is no unanimity of opinion.

Liquid‐Phase Synthesis of Halide Solid Electrolytes for All‐Solid‐State Batteries Using Organic Solvents

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study develops a scalable and universal liquid‐phase synthesis method of halide solid electrolytes using nitrogen‐containing solvents. The Li2YCl5−yBry (y = 0, 2, and 5) solid electrolytes synthesized via pyridine solvent exhibit an ionic conductivity over 1 × 10−4 S cm−1 at 25 °C.
