Water solubility in diopside
(1) Water solubility in pure diopside was measured. Water-saturated diopside crystals were synthesized using piston-cylinder and multi-anvil presses at 20-30 and 100 kbar and 800-1100oC from an oxide and hydroxide starting mixture containing 10 % excess silica. The water concentration in diopside …

Determination of the water solubility of the fungicide chlorothalonil
… procedure was developed and used to measure the water solubility of chlorothalonil at temperatures ranging from 8.5 to 37.5 °C. The effect of formulation chemicals present in BRAVO®500, a pesticide formulation containing chlorothalonil, on the apparent water solubility of chlorothalonil was also …

Biodegradation, water solubility and characterisation studies of unresolved complex mixtures (UCMs) of aromatic hydrocarbons
… particular emphasis on their biodegradability, water solubility and composition. To assess persistence in the environment, an 'aromatic' UCM was isolated from Tia Juana Pesado crude oil (Venezuela) and this UCM exposed to the hydrocarbon degrading bacterium Pseudomonas fluorescens (Texaco). Five …

Synthesis of Water Soluble Quantum Dots and their Application for Enzymatic Activity Measurements
… of "cap exchange" were tested to enable forming water-soluble QDs with minimal aggregation .The QD-mercaptoacetic acid is simple to synthesize and has good water-solubility, but the QDs are not stable. The direct attachment of peptide molecules to the QDs can passivate the surface and enable …

Organic Sulfur-Bearing Species as Subsurface Carbon Storage Vectors
… mechanisms to generate biologically refractory water-soluble organic molecules. Such molecular vectors could be sequestered in shallow, saline, contaminated aquifers through solubility trapping. Sulfur-rich oils were analyzed with gas chromatography mass spectrometry and Fourier transform ion …

Fabrication of water-soluble gold nanoparticle aggregates
… with a polar head group. A two-phase test of the water-solubility indicated that the aggregates were fully soluble. TEM images showed a slight increase in size, though similar morphology to the insoluble aggregates. The ability to induce water solubility in the aggregates opens up many potential …

Improved Properties of Natamycin Upon Formation of Cyclodextrin Inclusion Complexes
Natamycin is an antimycotic with very low water solubility and extremely high photosensitivity, which is used to extend the shelf life of shredded cheese products. The objectives of this research are: (a) to find a new delivery system for natamycin, which increases its aqueous solubility and (b) to …

Synthesis and Spectroscopic Study of Anticancer agent A-007 Prodrugs and Progress Towards the Synthesis of Tetramic acid Antibiotics
… A-007 as a broad-scale therapeutic is its poor water solubility. To make use of this promising anticancer drug either orally or intravenously, the short-term obstacle must be to overcome the limited solubility of A-007 in water. There are several approaches to overcome this obstacle. The first …

Thermodynamics of Polyamide Separation Membrane in Contact With Aqueous Solutions
The absorption of water in reverse osmosis membranes FT30 and LF10 is investigated by a combination of measurements of water mass uptake and biaxial stress as a function of relative humidity. Water solubility in polyamide active layer is 12 wt% at a relative humidity of 95%. The slope of a water …

Strain-promoted Stapled Peptides for Inhibiting Protein-protein Interactions
… the Sondheimer dialkyne suffers from poor water-solubility; it decomposes rapidly in aqueous solutions which limits its application in biological systems. This dissertation describes the design and synthesis of new substituted variants of the Sondheimer dialkyne with increased solubility …

The Reaction of a Water Soluble Platinum Compound with Methionine and Derivatives
Water soluble platinum complexes are a recent area of emphasis of cisplatin chemistry. The water soluble complexes could have a reduced toxicity compared with cisplatin. Oxaliplatin, which has an oxalate leaving group, has previously been shown to have less nephro-toxicity and higher water …

Identification of the products and mechanism of decomposition of thiazate
… transition metals similar to dithiszone but water soluble. His approach was to to sulfonate the benzene rings thus giving water solubility because of the ionic nature of the sulfonic acid. The new reagent-tensed thiazate--was quite successful in its purpose, but the sections of the compound …

Synthesis of a Water Soluble Resveratrol Derivative as a Potential Anti-Cancer Drug.
<p>Research on development of water soluble anti-cancer drugs is one of the great challenges of modern medicinal chemistry. Resveratrol (Res) is one of the many phytoalexins producing stilbenoids present in several medicinal plants, grape skin, peanuts, and red wine. It has been found to exhibit …

Studies on water-soluble taxol derivatives
… mechanism of action. Unfortunately, taxol is not water-soluble and therefore must be given in conjunction with emulsifying agents. Modifications of taxol were carried out in order to prepare water-soluble taxol derivatives. The C-2’ hydroxyl group of taxol was substituted with various groups to …

Synthesis of Resveratrol Ester Derivatives
… the lengths of the methylene chain we varied the water solubility of the resveratrol derivative. This brought the research closer to the goal of determining how this would affect the binding ability to HSA. Currently three derivatives have been synthesized and purified once by column …

Promoting pulp and paper mill material circularity: functionalised organic-inorganic cellulosic mulch films
Water scarcity, fertiliser run-off, and weeds competing for resources reduce forestry and agricultural productivity. Conventionally, fossil-fuel-based synthetic mulch films have been used to mitigate soil water loss, as a matrix for the slow-release of fertiliser, and for UV-vis light blocking to …
