Ceramics: Sintering and Microstructure

During this stage, the microstructure of the samples evolves (see Figure 1). Figure 1 Sintered Powder and microstructure. Source Krell et al.[8]. Pores, second phases and grain size have all an important influence on many of the final properties of ceramics. In general, the porosity has a more pronounced effect than a second phase or the grain ...

Recommended SDS PAGE Stain Protocols - UF Chemistry

In this staining protocol, all reagents are prepared immediately prior to use, including the Commassie blue stain and destain solutions. It is our experience that using fresh reagents gives a darker, more consistent stain with a lower background. In addition, the use of fresh reagents will minimize any contamination (keratin) of the gel.

GUIDELINES FOR HEMATOXYLIN & EOSIN STAINING

Bluing reagents change the reddish – purple hematoxylin to a blue or purple blue color. It is a pH dependent reaction and occurs in an alkaline solution. a. Troubleshooting. Reddish color of a stained section is due to inadequate bluing. Bluing reagents should have a pH of approximately 8. It is not possible to over-blue a section.
