Crystal Initiation Structures in Developing Enamel: Possible Implications for Caries Dissolution of Enamel Crystals [PDF]

Frontiers in Physiology, 2017
Investigations of developing enamel crystals using Atomic and Chemical Force Microscopy (AFM, CFM) have revealed a subunit structure. Subunits were seen in height images as collinear swellings about 30 nM in diameter on crystal surfaces. In friction mode

Effects of cold plasma, high hydrostatic pressure, ultrasound, and high-pressure carbon dioxide pretreatments on the quality characteristics of vacuum freeze-dried jujube slices

Ultrasonics Sonochemistry, 2022
Pretreatment combined with vacuum freeze-drying is an effective technique to extend the storage period of jujube fruits and reduce energy consumption and cost; however, the effects of pretreatment on the quality characteristics of jujube during vacuum ...

Freeze-fracture-etching Electron Microscopy for Facile Analysis of Yeast Ultrastructure

Bio-Protocol, 2017
We describe a streamlined method that enables the quick observation of yeast ultrastructure by electron microscopy (EM). Yeast cells are high-pressure frozen, freeze-fractured to cut across the cytoplasm, and freeze-etched to sublimate ice in the cytosol
