Inclusive laboratory activity

One of the points made in Schwenz and Moore was that the physical chemistry laboratory should better reflect the range of activities found in current physical chemistry research. This is reflected in part by the inclusion of modem instrumentation and computational methods, as noted extensively above, but also by the choice of topics. A number of experiments developed since Schwenz and Moore reflect these current topics. Some are devoted to modem materials, an extremely active research area, that I have broadly construed to include semiconductors, nanoparticles, self-assembled monolayers and other supramolecular systems, liquid crystals, and polymers. Others are devoted to physical chemistry of biological systems. I should point out here, that with rare exceptions, I have not included experiments for the biophysical chemistry laboratory in this latter category, primarily because the topics of many of these experiments fall out of the range of a typical physical chemistry laboratory or lecture syllabus. Systems of environmental interest were well represented as well. 

Packaged as a commercial product, NPVs have a remarkable shelf life. The occluded virions, within the protective inclusion-body protein, are among the most stable entomopathogens, compared with other microorganisms and microparasites, such as bacteria, fungi, protozoa, and nematodes. In the laboratory, lyophilized, frozen, or simply refrigerated NPV inclusion bodies, stored in darkness, remain active for many years, even decades... 

Inclusion protects unsaturated fatty acids from aging however, this protection is not perfect, as amylose itself also complexes oxygen753 756 (see Fig. 48). Unsaturated acids have a specific pattern of the carbon chain because at least two sp2-hybridized carbon atoms are present, causing geometrical isomerism. The frans-isomer does not fit perfectly into the cavity of amylose. Another report indicates that starch complexation with tannic acid has no effect on its activity against experimental ulcers in laboratory rats.757...
