TL;DR: A comparison of methods based on XRD patterns for calculating crystal size for hydroxyapatite obtained from cow, pig, and chicken bones found the Scherrer method (straight line model) for considering all peaks led to unreasonable values.

TL;DR: An overview of the properties of various natural and synthetic fibers for the fabrication of pure natural composites and the combination of both natural/synthetic fibers-based hybrid composites, bio-based resins, various fabrication techniques, chemical and mechanical properties of fibers, the effect of chemical treatment and the influence of nanoparticles on the composite materials.

TL;DR: The modified Williamson–Hall (W–H) method in the uniform stress deformation model (USDM) utilized in this paper is to provide a new approach of using the W–H equation, so that a least squares technique can be applied to minimize the sources of errors.

TL;DR: In this article, two new thermally activated delayed fluorescence (TADF) dyes obtained from D-A-D′ type, consisted of 2-(9H-carbazol-9-yl)-3-(3-methoxy-9 H-CARBASOL-9yl)-9 H H-xanthen and 2-(3,6-di-tert-butyl-9H -CARBASSO-9L-Xanthen)-3 H H xanthen derivative and carbazole derivatives have played important roles

TL;DR: In this article, an optical laser-based method is presented to visualize repli- cation of microperiodic profile structures in polymers, which can be used to test the surface relief formation during the combined ion etching of crystalline Si 100 and replication of this structure using UV light hardening and hot embossing.
