Solvents are widely used in wood conservation for either dissolving polymers for consolidation purposes or for removing dirt or foreign matter, which was applied during previous conservation. Solvents may cause temporary swelling of the wood, and when they evaporate wood returns back to its original size. They may form complexes with wood components when unlimited swelling arises as a consequen...

Weakly ferromagnetic cobalt nanoparticles can assemble spontaneously into nanosized "bracelets" when dispersed in organic solvents containing resorcinarenes as surfactants. Bracelet self-assembly occurs in solution and is directed by magnetic dipolar interactions, whereas nanoparticle rings with larger diameters are produced by evaporation-driven flow on wetted surfaces.

A method for solubilization of pristine fullerene (C(60)) in water was proposed by directly using bovine serum albumin (BSA) as a "solubilizer" by means of the unfolding mechanism. C(60) aqueous solution with a small distribution size, excellent dispersion stability and high dispersion concentration was obtained without the use of derivatization and organic solvent.

The biomimetic reduction of anti-inflammatory drug, nimesulide (1) with sodium borohydride catalyzed by 5,10,15,20-tetraarylporphyrinatoiron(III) chlorides [TAPFe(III)Cl] has been studied in organic solvents under anaerobic and aerobic conditions.

A novel organic-inorganic hybrid of triethanolamine linked covalently with a new building block of {VMo6O25} was synthesized in aqueous solution, and the hybrid was further assembled with copper-triethanolamine complexes to form a ring-like structure. This work represents an advance in the organic functionalization of polyoxometalate performed in aqueous solution instead of an organic solvent.

Previously, we reported a method for facile purification of oligonucleotides labeled with hydrophobic dyes, based on the solubility difference between the hydrophilic DNA and unreacted dye. Here, we present a new purification method applicable to any dye regardless of its hydrophobicity. We exploited the population shift of a fluorescent dye in a low-pH aqueous solution from its anionic form to...

We show that the same low molecular weight gelator can form gels using three different methods. Gels were formed from a high pH solution either by adding a salt or by adding an acid; gels were also formed by adding water to a solution of the gelator in an organic solvent. The mechanical properties for the gels formed by the different methods are different from one another. We link this to the n...

A method for the rapid preparative isolation of highly purified avidin using h.p.l.c. on a powerful cation-exchanger TSK SP-5PW column has been developed. The method is based on the following properties of avidin: solubility at a high (NH4)2SO4 concentration, stability and relatively low solubility in organic solvents, as well as the strongly cationic nature of the molecule. Riboflavin-binding ...

Hydrogen-bond-mediated complexation of a CG base pair by a hexylureido phthalimide and a hexylureido isoindolin-1-one was studied by (1)H NMR spectroscopy in an organic solvent. Chemical shift data indicate that both receptors effectively bind the CG base pair from the major groove side.
