Marron glacé that a "marron glacé" is a confit marron that is covered in caramel. The 1767 book "L'agronome, ou dictionnaire portatif du cultivateur" claimed that the best marrons came from the Dauphiné region in southeastern France, and contained instructions for preparing marron glacés. Chestnuts are covered with a membrane, known as a pellicle or episperm, which closely adheres to the fruit's flesh and must be removed because of its astringency. Marron nuts have a pellicle which is "superficially attached to the nut", making it easily removable from the fruit. Some chestnuts have two cotyledons usually separated with deep grooves penetrating nearly
Conductive characteristics in coated synthetic fabrics the sodium perchlorate dopant system was the least effective. The power density per unit area achieved in polypyrrole coated polyester–Lycra fabric with 0.027 mol/l of AQSA acting as dopant was 430 W/m2. The power density per unit area achieved for the sodium perchlorate system, using the same synthesis conditions, was 55 W/m2. Conductive characteristics in coated synthetic fabrics Conductive characteristics in coated synthetic fabrics demonstrates an energy current across a specific woven synthetic material, such energy generation in fabrics coated with a conductive polymer as found in polypyrrole. First validated by D.D.S. developer M.H.Webb, the discovery showed that when PET
