The carbodiimides reacted slowly with water under acidic conditions to yield ureas. These systems were compared with solid mixtures of other PPO derivatives with sodium sulfate as a drying agent, as chemically water-binding solid scintillators in 3H and 14C counting. Both the chemically and the ...
In the case of using phenol and acrylonitrile (molar ratio of 1:4) as reactants, the reaction was carried out in a 50 ml one-necked glass flask at 80 °C fixed with a water-cooled condenser. After the reaction, the catalyst was separated from the mixture by centrifugation, and the ...
Product Description SODIUM HYDROSULFITE, also known as sodium hydroxide, is a white sandy crystal or light yellow powder chemical product, melting point 300 (decomposition), ignition temperature 250, insoluble in ethanol, soluble in sodium hydroxide solution, in contact with water It reacts ... ...

This structure has not been reported experimentally for the Li and Na case, possibly as due to a tendency to decompose into Li- or NaFeO2 and Fe2O347,48.For some of the ionic conductors like K-BASE, which consists of K-β”−Al2O3 with minor amounts of K-β-Al2O3 and ZrO2...
A solid soap is described composed of a hard and elastic gel based on starch, potassium and sodium salts of higher fatty acids and water.< P> The soap as herein described has the same detergent capacity as other soap known at the present... John A. S. Harding 被引量: 1发表: 1984年...
Borax (sodium tetraborate) acts as a weak crosslinker between the PVA polymers21. In order to assess the properties of these fluids, their storage (G′) and loss (G″) moduli were measured in a rheometer using a cone-plate geometry with an angular frequency ω of 10 rad/s (Fig. 1)....
For your information, Slime is created when PVA, in other words Polyvinyl acetate, comes in contact with sodium borate, sodium tetraborate, or disodium tetraborate. Slime is a very easy craft that me and my class love so much, that we make it every Monday! We recommend the following slimes...
going to still higher ionic strengths (e.g., 100 mM NaCl + 50 mM sodium phosphate), but the solutions become turbid, indicating the onset of precipitation of the chromatin.” As discussed above, the interpretation that the chromatin aggregates are insoluble precipitants was commonplace at...
We then modified reversibly immobilized proteins with protein-reactive ATRP initiators and, after ATRP, we released and analyzed the protein polymers. The activity and stability of PARIS-synthesized and solution-synthesized conjugates demonstrated that PARIS was an effective, rapid, and simple method to...
