This study, done for the joint DOE-EPA Laboratories for the 21st Century program ("Labs 21"), used a simplified computer model to analyze the effects of energy efficiency measures in laboratory buildings in four different climates: those of Minneapolis, Denver, Seattle, and Atlanta. Results show that using variable-air-volume fume hoods can reduce lab energy costs as much as$1 per square foot in any climate. Energy-recovery systems such as enthalpy wheels also save varying amounts of energy and money in all climates. Savings for other measures, such as heat pipes and evaporated cooling, are also included.

Gold has been used for immunocytochemistry since 1971 when Faulk and Taylor discovered adsorption of antibodies to colloidal gold. It is an ideal label for electron microscopy (EM) due to its high atomic number, which scatters electrons efficiently, and the fact that preparative methods have been developed to make uniform particles in the appropriate size range of 5 to 30 nm. Use in light microscopy (LM) generally requires silver enhancement (autometallography; AMG) of these small gold particles. Significant advances in this field since that time have included a better understanding of the conditions for best antibody adsorption, more regular gold size production, adsorption of other useful molecules, like protein A, and advances in silver enhancement. Many studies have also been accomplished showing the usefulness of these techniques to cell biology and biomedical research. A further advance in this field was the development of Nanogold{trademark}, a 1.4 nm gold cluster. A significant difference from colloidal gold is that Nanogold is actually a coordination compound containing a gold core covalently linked to surface organic groups. These in turn may be covalently attached to antibodies. This approach to immunolabeling has several advantages compared to colloidal gold such as vastly better penetration into tissues, …
