The arrangement of layers of natural long fibers that compose a polymeric composite can result in a final material with greater mechanical strength, in addition to replacing synthetic glass and carbon fibers. This study proposed different configurations of layers of loofah fibers (Luffa cylindrica) to...

inclusion of impurities, such as foreign ions, in the crystalline structure.Other minerals — for example, sulfur, which is yellow, and malachite, which is bright green — are said to have inherent coloration because their color is a consequence of their chemical makeup and does not vary ...
Why is glass an amorphous solid? Why does temperature increase when water condenses? How would a solute affect the boiling point of water? Why do minerals have different crystal shapes? How does water affect the process of mass movement?
(i) Residual thermal stresses arise when a glass object is cooled. Why? (ii) Are thermal stresses introduced when a glass object is heated? Explain. (iii) Drying shrinkage is greater for slip cast or hydroplastic products that have smaller clay pa...
Glass is made by melting the ingredients together at very high temperatures and then cooling it very rapidly. This process is known as vitrification. When the glass cools too slowly, it can become crystalline, which means that its structure is no longer amorphous. ...

Herein, we have succeeded a series of alicycle-fused Schiff bases as a new class of BioAIEgens derived from natural rosin. The alicyclic moieties help to rigidify the flexible structure of the non-emissive Schiff base to light up its fluorescence. Furthermore, the luminescence properties could...
