The invention relates to an arrangement at measurement of pH or another chemical property detectable by dye indicators. To provide a simple and safe solution, the measuring part is formed of a glass sheet or a similar substrate, the substrate being coated with a dye film, which is arranged ...
And we analysis a physical and chemical property and relation to degradation enzyme in different trees and periods. The results are as follows 1. The optimal cultural conditions of Coriolus ver Bicolor : the optimum temperature was 30℃, pH 5.5. Lentinus edodes : the optimum temperature was 25...

Instruments register a signal due to some physical or chemical property of the solution. For example, pH meters measure the electrode potential which must be related to the [H+] or [OH-] of the solution by comparison against known [H+] or [OH-] standard buffers. In other words, the ...
The physical and/or chemical crosslinking of hydrogels in the swollen state can be tuned by hydrophobic groups (–nCH2–, –nCH2-CH2-O–, and –nSi-O–) and hydrophilic groups (–NH2,–COOH, –OH, –CONH–, and –SO3H), which can control the volume changes and the sol–gel ...
Using other biopolymers, relatively dense hydrogels can be combined in IPNs to generate stiff matrices with tougher mechanical properties, more widely controllable physical properties, and more efficient drug loading than are attainable with simple physical or chemical hydrogels (Hoare & Kohane, 2008). ...
PBS溶液的pH是恒定的,基本在7.2-7.4之间,而磷酸盐缓冲液有pH6.0-8.0等不同pH值。 磷酸盐缓冲液(PH6.8)(药典)主要由磷酸氢二盐、磷酸二氢盐组成,不含氯化钠,不含钙离子和镁离子,pH 值为 6.8。主要用于免疫组织、组织切片或其他常规用途。 磷酸盐缓冲液(PH6.8)(药典)上下游产品信息 ...

In aqueous environments, acidity is arguably the most important property dictating the chemical, physical, and biological processes that can occur. However, in a variety of environments where the minuscule size limits the number of water molecules, the conventional macroscopic description of pH is no...
