Native corn starch has a lack of characteristics such as low thermal stability, resistance to shear force, and high tendency retrograde. To address this problem, it needs be modified improve its application in the food sector. Hydrothermal modification is one physical modifications by heating above gelatinization temperature with limited water content. In study, native was using various methods...

Key properties of polyimide-coated optical fibers, unaged and exposed to various harsh environments, were investigated. The main intent was to model extreme conditions that can be encountered in medical applications of the fibers. A fiber designed by OFS showed good strength and was able to withstand exposure to extreme heat and humidity, multiple autoclave cycles, extended water soak and immer...

They are used and known from the tanners for quite two thousand years (1) by different civilization (Mesopotamian, precolombian...) and till the XIX century mainly into the form of raw, untreated material like bark. Than chemical companies start to increase he yield of tan content by proceeding into extraction with autoclave and spraydrying leading to extract such as Chestnut or Mimosa having m...

This review considers the influence of resin-rich volumes (RRV) on static and dynamic mechanical physical behaviour fibre-reinforced composites. The formation, shape size, measurement RRV in composites, depending upon different fabric architectures manufacturing processes, is discussed. majority studies show a negative effect composite materials. main factors that cause are (a) clustering fibre...
