Mutarotation was discovered by Dubrunfaut in 1846, when he noticed that the specific rotation of aqueous sugar solution changes with time.
Researchers such as Francisco Blanco et al. have used protein NMR to show that beta-hairpins can be formed from isolated short peptides in aqueous solution, suggesting that hairpins could form nucleation sites for protein folding.
Thus, it has been known for many years that, due to repulsive Coulombic interactions, electrically charged macromolecules in an aqueous environment can exhibit long-range crystal-like correlations with interparticle separation distances often being considerably greater than the individual particle diameter.
In Malay cooking, an aqueous extract is used to colour glutinous rice for kuih ketan (also known as pulut tai tai in Peranakan/Nyonya cooking) and in nyonya chang.
Standard phenol extraction is used to obtain DNA from test or reference (karyotypically normal individual) tissue, which involves the combination of Tris-Ethylenediaminetetraacetic acid and phenol with aqueous DNA in equal amounts.
The leaf aqueous-ethanol extract of Feruia foetida has shown antioxidant and antihemolytic activities.
In 1652, Olaus Rudbeck (1630–1702), a Swede, discovered certain transparent vessels in the liver that contained clear fluid (and not white), and thus named them hepatico-aqueous vessels.
The term milk of magnesia was first used for a white-colored, aqueous, mildly alkaline suspension of magnesium hydroxide formulated at about 8%w/v by Charles Henry Phillips in 1880 and sold under the brand name Phillips' Milk of Magnesia for medicinal usage.
Paper marbling, a method of aqueous surface design in which paper or fabric is decorated with a spotted pattern similar to stone, as well as other swirled and combed patterns
Kikunae Ikeda from the Tokyo Imperial University isolated glutamic acid as a new taste substance in 1908 from the seaweed Laminaria japonica, kombu, by aqueous extraction and crystallization, and named its taste "umami".
In another system with benzaldehyde, Montmorillonite K-10 and zinc chloride in aqueous THF under ultrasound the reaction time is reduced to 3 hours (composition 55:45).
Research conducted by the University of Natal found that aqueous extracts of P. myrtifolia proved effective against Candida albicans.
The demethylation of Methylene Blue in aqueous solution using heat and alkali produces a mixture of Azure A, Azure B, Methylene Violet and Methylene Blue.
Slip is an aqueous suspension of a clay body, which is a mixture of clays and other minerals such as quartz, feldspar and mica.
Latanoprost is commercially formulated as an aqueous solution in a concentration of 0.005% preserved with 0.02% benzalkonium chloride (BAC).
The Tovex family of products, sometimes generically called "water gels," were developed by the old Explosives Department at DuPont (E.I. du Pont de Nemours & Company, Inc.) in the mid-to-late 1960s when pelletized TNT was included in aqueous gels to create a slurry form of ANFO that displayed water-resistant properties in wet bore holes.
In addition some uveal regions have special functions of great importance, including secretion of the aqueous humour by the ciliary processes, control of accommodation (focus) by the ciliary body, and optimisation of retinal illumination by the iris's control over the pupil.
Water gel explosives are produced by combining nitroparaffins, usually nitromethane, with an aqueous salt solution and a gelling agent.
