The viscosity assay is conducted at 5% using a Brookfield RVF, spindle 2, speed 10 rpm, at 25°C. The viscosity range is provided as a quality control specification. The viscosity molecular weight (Mv) is determined through a rheological method and is an approximation. According to supplier information, this product has the ability to thicken a wide variety of organic solvents at various temperatures. Typical organic solvents include most halogenated hydrocarbons, various ketones, alcohols, aromatic hydrocarbons, and esters. However, it is generally not soluble in aliphatic hydrocarbon solvents, glycols, diols, and aliphatic ethers.

Additive manufacturing technologies based on layer-by-layer deposition of material ejected from a nozzle provide unmatched versatility but are limited in terms of printing speed and resolution. Electrohydrodynamic jetting uniquely allows generating submicrometer jets that can reach speeds above 1 m s-1, but

Previous studies have demonstrated that Separan AP-30, a drag-reducing polymer, significantly decreased the formation of atherosclerotic plaques in rabbits fed a high-cholesterol diet. Furthermore, Separan AP-273, a polymer similar to but longer than Separan AP-30, markedly increased cardiac output in
