Our interest in PDMS as an epoxy modifier lies partly in its low Tg relative to the ATBN and CTBN modifiers. Up to this time, however, improvements in K,c through copolymerization of dimethyl siloxane with TFP and DP siloxane require raising the Tg of the siloxane modifier above that of PDMS, as shown by Table 1. It is hoped that increased understanding and control of the synthesis and morphologies of siloxane-modified epoxies will make it possible to retain the low Tg of the modifier while raising the fracture toughness of the resin. The true value of this objective could eventually be shown by measurement of Klc at temperatures below ambient. 

Fig. 2.35).The synthesis and morphology of more complex trifunctional branched graft copolymers have recently been discussed. Gido et al. (1996) prepared PS2-PI-PS2 (H-shaped) and (PS-PI)PI(PS-PI) ( -shaped) copolymers (see Fig. 2.33). The observed morphology of these samples was compared to the theory of Milner, the comparison being facilitated by considering the H- and -shaped molecules to each be composed of two single graft copolymers. This generally produced a satisfactory mapping onto the phase diagram in Fig. 2.34.

Cell line selection is one of the traditional and effective approaches to enhancing metabolite accumulation, and biochemical studies provide the fundamental information for the intentional regulation of secondary metabolism in plant cells. In a carrot suspension culture regulated by 2,4-dichlorophenoxyace-tic acid, Ozeki et al. [7] found that there was a correlation between anthocyanin synthesis and morphological differentiation for somatic embryogenesis they also demonstrated the induction and repression of phenylalanine ammonia lyase (PAL) and chalcone synthase correlated with formation of the respective mRNAs. Two biosynthetic enzymes, i. e., PAL and 3-hydroxymethylglutaryl-CoA reductase, were also related with shikonin formation in Lithospermum erythro-rhizon cultures [8]. 

All products produced by three methods have similar morphology at the initial stage of the process. The morphology has undergone changes in the course of the further treatment of product. The synthesis time is one of the key moments in the nanostructure formation. The peculiarities of synthesis and morphology of some products produced by the arc method in the liquid phase are considered and discussed below.

Benz[a]anthracene was mutagenic to Salmonella typhimurium in the presence of an exogenous metabolic system. It was also mutagenic to mammalian cells in vitro in the presence of an exogenous metabolic system. In cultured mammalian cells, benz [a] anthracene induced unscheduled DNA synthesis and morphological transformation.

Rhodanine (XXXIV) has been found to inhibit the multiplication of ECHO 12 virus, one of the enteric RNA viruses. Other strains of ECHO and various other RNA and DNA viruses were insensitive. It produced 95 per cent inhibition of virus growth in monkey kidney cells at 17 pg/ml. Cellular RNA synthesis and morphological appearance were unaffected by 150 pg/ml. This work indicated that rhodanine prevented synthesis of the viral protein coat. All the substituted rhodanines examined were inactive or only slightly active and generally more toxic than the unsubstituted compound [177].

There is, thus, much interesting and important work yet to be done on the acm pathway and on antibiotic synthesis and morphological differentiation in other strepio-mycetes. One can but hope that furiding agencies around the globe will see the value of continuing this work and will provide the funds to support it.
