This review describes protein purifications from cell culture medium or cell-lysate by high speed counter-current chromatography using the cross-axis coil planet centrifuge. Purifications were performed using aqueous two phase systems composed of polyethylene glycols and dextrans.

An efficient modular approach for single-site incorporation of two independent functionalities (amines and alkynes) into aldehyde-containing oligosaccharides concurrently by using a one-pot gold-mediated three-component coupling reaction in aqueous medium under mild conditions has been developed.

The straightforward synthesis of novel enzyme-metalNP nanobiohybrids in aqueous medium was developed. These new nanobiohybrids were excellent multivalent catalysts combining both activities in various sets of synthetic reactions even at ultra-low concentrations (ppb amount).

Previous work on the vitamin B12 content of the aqueous humour (Phillips, Ainley, van Peborgh, Watson-Williams, and Bottomley, I968) suggests that the levels found in a series of mainly elderly patients (mean: 299 pg./ml.) are of the same order as those found in cerebrospinal fluid (mean: 21 pg./ml.) (Kidd, Gould, and Thomas, I963). As an extension of this study, the response of aqueous vitamin...

This study investigated the interaction between microbial growth and cell elution, and their influence on resultant microbial distribution between the aqueous and solid phases during solute transport in a sandy, low-organic-carbon-content porous medium. Miscible displacement experiments were conducted with salicylate as the model compound, and with different initial conditions (e.g., substrate ...

Abstract. The progress of the oxidative polymerization of aniline with ammonium peroxydisulfate in aqueous medium has been monitored in situ by attenuated total reflection Fourier transform infrared spectroscopy. The growth of polyaniline film at the crystal surface as well as changes proceeding in the surrounding aqueous phase is reflected in the spectra. It has been shown that in aqueous solu...

A new experimental method for in vitro release studies of poorly soluble drugs from polymeric micelle systems was developed using a hydrotropic agent, sodium salicylate. It is difficult to maintain a good sink condition for poorly water-soluble drugs, such as paclitaxel (PTX), because of their low aqueous solubility. In this study, a good sink condition for PTX was achieved by using aqueous sod...

We compare extensive experimental results for the gravity-driven steady drainage of oil-in-water emulsions with two theoretical predictions, both based on the assumption of Poiseuille flow. The first is from standard foam drainage theory, applicable at low aqueous volume fractions, for which a correction is derived to account for the effects of the confinement of the emulsion. The second arises...

Ionically crosslinked alginate hydrogels are attractive scaffolds because of their biocompatibility and mild gelation reaction that allows for gentle cell incorporation. However, the instability of ionically crosslinked hydrogels in an aqueous environment is a challenge that limits their application. This report presents a novel method to control the dimensions and mechanical properties of ioni...
