Multilayer Density Analysis of Cellulose Thin Films

Frontiers in Chemistry, 2019
An approach for the multilayer density analysis of polysaccharide thin films at the example of cellulose is presented. In detail, a model was developed for the evaluation of the density in different layers across the thickness direction of the film.

Performance of glass fiber reinforced polyamide composites exposed to bioethanol fuel at high temperature

npj Materials Degradation, 2022
The increasing use of bioethanol fuel, as a promising carbon-neutral alternative to petroleum-based gasoline, has raised concerns on compatibility issues between bioethanol and the polymer components used in the automotive fuel system.

Abstracts of the Papers Printed in the Philosophical Transactions of the Royal Society of London
Abstract The author observes, that, in the mature blood-corpuscle, there is often seen a flat filament, already formed within the corpuscle. In Mammalia, including Man, this filament is frequently annular ; sometimes the ring is divided at a certain part, and sometimes one extremity overlaps the other.

Analysis of Colorfastness in Metallic Prints Using Absorption Spectroscopy

Journal of Spectroscopy
Color is essential for the fashion and art of fabrics, with its retention being a quality measure of great significance for the brand and user. The colorfastness of some metallic fabrics has been established using absorption spectroscopy, by determining ...

Combined granulation–alkali activation–direct foaming process: A novel route to porous geopolymer granules with enhanced adsorption properties

Materials & Design, 2023
High-value applications, such as adsorbents, have drawn attention to geopolymers. In several of those applications, having the geopolymer as porous spherical particles is beneficial.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...
