ISO 9227
ISO 9227 specifies the apparatus, test solutions, and procedures for conducting three types of salt spray corrosion tests: • NSS – Neutral Salt Spray • AASS – Acetic Acid Salt Spray • CASS – Copper-Accelerated Acetic Acid Salt Spray These tests are used to assess the corrosion resistance of metallic materials, with or without protective coatings.
SAE J400
SAE J400 simulates gravel impact to assess the chip resistance of coatings using a Gravelometer. Gravel is blown with compressed air onto the panel, then tape lifts the detached coating. Results are evaluated by chip counting or visual comparison with reference images and reported in a number–letter format (10–0 & A–D).

Aerogel - Materials of the century
Aerogel is a synthetic porous ultralight material derived from a gel, in which the liquid component for the gel has been replaced with a gas. The result is a solid with extremely low density and low thermal conductivity. Nicknames include frozen smoke, solid smoke, solid air, solid cloud, blue smoke owing to its translucent nature and the way light scatters in the material. It feels like fragile expanded polystyrene to the touch. Aerogels can be made from a variety of chemical compounds.

Selective Extraction of Fatty Acids and Carotenoids from Microalgae by Supercritical Fluid Systems
Selective Extraction of Fatty Acids and Carotenoids from Microalgae by Supercritical Fluid Systems Spirulina maxima, a type of microalgae, is of great interest to the cosmetic, food, and pharmaceutical industries due to its chemical composition. The blue-green cyanobacterium is a source of carotenoids, which are rich in Vitamin A and act as powerful antioxidants.
Micro Algae | Uses for Supercritical Fluids
Supercritical fluid extraction is an environmentally clean technology using carbon dioxide to isolate a variety of natural compounds from micro algae. This benign extraction process provides: - high selectivities - short extraction times - leaves no toxic solvent residues in the extract
Aerogels | Uses for Supercritical Fluids
High temperature conversion of a liquid organic solvent to the supercritical state with subsequent venting Liquid CO2 displacement of an organic solvent with subsequent supercritical CO2 venting Supercritical CO2 extraction of an organic solvent at low temperatures
Nutraceuticals | Uses for Supercritical Fluids
Compared to traditional extraction methods, natural supercritical CO2 extraction has many benefits and is Generally Recognized As Safe (GRAS). Supercritical CO2 extraction eliminates exposure of the natural product to oxygen during the process and thus reduces oxidation of sensitive bioactive compounds. It also is a low temperature operation that does not promote thermal degradation of sensitive nutraceutical compounds . In addition, when the supercritical CO2 extract is depressurized, there are

Method for producing deproteinized natural rubber latex
1. A method for deproteinizing natural rubber latex comprising steps of: adding a urea denaturing agent for proteins and a surfactant to raw natural rubber latex; transporting the mixture through a fluid channel while agitating and mixing to denature proteins in raw natural rubber latex; and separating and removing the denatured proteins resulted from the previous step. 2. The method according to claim 1, wherein the urea denaturing agent for proteins is used in the form of a 0.01% to 1% by wei
Enzyme-assisted supercritical carbon dioxide extraction of black pepper oleoresin for enhanced yield of piperine-rich extract
Piperine, along with its isomer chavicine, is the alkaloid[1] responsible for the pungency of black pepper and long pepper. It has also been used in some forms of traditional medicine and as an insecticide.
