Application of environmental scanning electron microscopy in the development of detergents and personal products
Environmental scanning electron microscopy enables the observation of samples in their natural state with no preparation. Unilever Research employs this technology in the research and development of detergents and personal products with much success. The results presented are from various studies which demonstrate the versatility and utility of the technique. Vacuum sensitive samples such as microcapsules were successfully characterized, the efficacy of dental products was shown by monitoring an enamel surface before and after treatment, and the performance of an adhesive was assessed by dynamic experimentation. © 1993 Wiley‐Liss, Inc.
Bibliography of environmental scanning electron microscopy
Two updated lists of publications on environmental scanning electron microscopy are compiled. One list contains mainly those papers dealing with the development and instrumentation, while the other deals mainly with the applications of the technique. A brief introductory summary of the field is presented. © 1993 Wiley‐Liss, Inc.
Metabolism of individual fatty acids by sheep depot adipose tissue in vivo and in vitro.
1. 
1. Sheep adipose tissue and plasma have high stearate and low unsaturated fatty acid content compared to rat, dog and man. 
 
2. 
2. In control animals in vivo uptake as well as release of various fatty acids by adipose tissue could be demonstrated. In vitro net release occurred. Fasting resulted in a decrease in tissue stearate and increased release of fatty acids. Adrenaline and noradrenaline had minimal lipolytic effect in vivo and in vitro. 
 
3. 
3. Variations in the turnover rate of individual fatty acids were observed.
