“…Samples came from cores, side-wall cores, or outcrops, with total organic carbon contents 21% bv weight. and the -, samples were thermally kature on the basis of kerogen pyrolysis (27). Absolute concentrations of oleanane poorly reflect the level of input of oleanane precursors because concentrations of biological markers can vary by several orders of magnitude, depending mostly on the thermal maturity of the sample (28).…”

Oleanane has been reported in Upper Cretaceous and Tertiary source rocks and their related oils and has been suggested as a marker for flowering plants. Correspondence of oleanane concentrations relative to the ubiquitous microbial marker 17alpha-hopane with angiosperm diversification (Neocomian to Miocene) suggests that oleanane concentrations in migrated petroleum can be used to identify the maximum age of unknown or unavailable source rock. Rare occurrences of pre-Cretaceous oleanane suggest either that a separate lineage leads to the angiosperms well before the Early Cretaceous or that other plant groups have the rarely expressed ability to synthesize oleanane precursors.

“…1, D to F) detected low concentrations of oleananes. 27. Because immature shales in the Niger Delta were shown to have somewhat higher relative amounts of oleananes than mature ones (40), we used artificial maturation by pyrolysis to minimize the possible problems of comparing immature and mature samples.…”

“…Light-harvesting and energy-transfer properties of linear photoactive polymer systems have also been investigated (67)(68)(69). In some of the earliest work, a trapping molecule was attached to the polymer backbone, and the effect of trap sensitization through excitation of the main polymer chromophore was studied (70).…”

This article highlights areas of research at the interface of nanotechnology, the physical sciences, and biology that are related to energy conversion: specifically, those related to photovoltaic applications. Although much ongoing work is seeking to understand basic processes of photosynthesis and chemical conversion, such as light harvesting, electron transfer, and ion transport, application of this knowledge to the development of fully synthetic and͞or hybrid devices is still in its infancy. To develop systems that produce energy in an efficient manner, it is important both to understand the biological mechanisms of energy flow for optimization of primary structure and to appreciate the roles of architecture and assembly. Whether devices are completely synthetic and mimic biological processes or devices use natural biomolecules, much of the research for future power systems will happen at the intersection of disciplines.biotechnology ͉ nanotechnology ͉ photosynthesis ͉ photovoltaic R ecently, the National Academies and the Keck Foundation held a meeting to discuss the development of new applications for nanotechnology ¶ with the goal of identifying challenges where the convergence of nanoscience and physical and biosciences could provide a revolutionary outcome. One area clearly in need of new technologies is biological and biomimetic methods of energy conversion. Within this broad area, focus was given to two specific applications: the conversion of solar energy into useful electrical or chemical energy and the production of power for in vivo medical devices. The following sections will provide both an economic perspective on current photovoltaic (PV) technology and an overview of the various research efforts toward using or mimicking biological systems to improve current and future energy-conversion systems.

“…Marie 11 prepared fluorescent coating which was applied to many aspects especially outdoor coating due to its high ultraviolet durability. The synthetic approaches of fluorescent monomers [12][13][14] were complex and needed too much time and the yield was low. Zhu and Zhang 15 synthesized fluorescent monomer from 4-bromo-1,8-naphthalic anhydride and ethanol-amine via amidation, amination and quaterization.…”

Fluorescent monomer α-N-methacrylamide-β-naphthol (NMAMN) was synthesized by Friedel-Crafts reaction and incorporated into its polymers. The structure of α-N-methacrylamide-β-naphthol was optimized through the programme Gauss03 package implementing the 6-31G basis set. The spectroscopic properties were assessed for their effectiveness and the fluorescence intensity of autopolymer was enhanced significantly. Moreover, the fluorescent compounds showed good thermodynamic stability.
