Adjustment of Coatings Morphology and Particle Distribution of Layered Silicates by Freeze‐Drying for Improved Gas Barriers

Advanced Engineering Materials, EarlyView.
Freeze‐drying of layered silicate is the key to get coatings with superior gas barrier. Freeze‐drying of layered silicates modified with dodecylamine (DDA) is a highly effective technique for the preparation of barrier pigments that significantly mitigate the permeation of oxygen, water vapor, and hydrogen through polymer films containing these ...

The effect of voltage and time of exposure on surface hardness of resin modified glass ionomer cement

Dental Journal, 2007
Light intensity can affect the polymerization of resin-based material therefore it will also affect surface hardness. To compensate reduction of light intensity becaused of the input of low voltage (200 and 210 volt), the exposure time was prolonged to ...
