The invention relates to recombinant microorganisms that have been engineered to produce various chemicals using genes that have been repurposed to create a reverse beta oxidation pathway. Generally speaking, the beta oxidation cycle is expressed and driven in reverse by modifying various regulation points for as many cycles as needed, and then the CoA thioester intermediates are converted to useful products by the action of termination enzymes.

While studies of surface plasmons on metals have been pursued for decades, the more recent appearance of nanoscience has created a revolution in this field with "Plasmonics" emerging as a major area of research. The direct optical excitation of surface plasmons on metallic nanostructures provides numerous ways to control and manipulate light at nanoscale dimensions. This has stimulated the development of novel optical materials, deeper theoretical insight, innovative new devices, and applications with potential for significant technological and societal impact. Nano Letters has been instrumental in the emergence of plasmonics, providing its readership with rapid advances in this dynamic field. © 2010 American Chemical Society.

Localized Surface plasmon resonance (LSPR) sensors based on metal nanoparticles, a mode of signal transduction, and biological LSPR sensors, concerned with label-free detection, are studied. To find the functional form of the LSPR peak wavelength's dependence on the dielectric function of the medium, the analytical, frequency-dependent form from the Drude model of the electronic structure of metals is used. LSPR directly detects the target's refractive index and so it is a label-free sensor, in which the measured signal is due only to the presence of the target molecule. LSPR sensing is used to probe biomolecular interactions including nucleic acid hybridization and protein-carbohydrate, cytochrome-inhibitor, aptamer, protein, and toxinreceptor interactions. A scheme for LSPR-based gas sensing is developed by Karakouz et al., in which evaporated gold island films are coated with the polymers polystyrene sulfonic acid (PSS) and polystyrene (PS).

High-transition temperature (high-Tc) superconductivity in the iron pnictides or chalcogenides emerges from the suppression of the static antiferromagnetic order in their parent compounds, similar to copper oxide superconductors. This raises a fundamental question concerning the role of magnetism in the superconductivity of these materials. Neutron scattering, a powerful probe to study the magnetic order and spin dynamics, plays an essential role in determining the relationship between magnetism and superconductivity in high-Tc superconductors. The rapid development of modern neutron time-of-flight spectrometers allows a direct determination of the spin dynamical properties of iron-based superconductors throughout the entire Brillouin zone. In this paper, an overview is presented of the neutron scattering results on iron-based superconductors, focusing on the evolution of spin-excitation spectra as a function of electron and hole doping and isoelectronic substitution. Spin dynamical properties of iron-based superconductors are compared with those of copper oxide and heavy fermion superconductors and the common features of spin excitations in these three families of unconventional superconductors and their relationship with superconductivity are discussed. © 2015 American Physical Society.

Chemists have long been fascinated by metalloenzymes and their chemistry. Because enzymes are essential for biological processes and to life itself, they present a key to understanding the world around us. At the same time, if chemists could harness the reactivity and selectivity of enzymes in designed transition-metal catalysts, we would have access to a powerful practical advance in chemistry. But the design of enzyme-like catalysts from scratch presents enormous challenges. Simplified, designed systems often don't provide the opportunity to mimic the complex features of enzymes such as selectivity in polyfunctional environments and access to reactive intermediates incompatible with bulk aqueous solution.Extensive efforts by numerous groups have led to remarkable designed metalloproteins that contain complex folds, including well-defined secondary and tertiary structure surrounding complex polymetallic centers. These structural achievements, however, have not yet led to general approaches to useful catalysts; continued efforts and new insights are needed. Our efforts have combined the attributes of enzymatic and traditional catalysis, bringing the benefits of polypeptide ligands to bear on completely nonbiological transition-metal centers. With a focus on designing useful catalytic activity, we have examined rhodium(II) carboxylates, bound to peptide chains through carboxylate side chains. Among other advantages, these complexes are stable and catalytically active in water.Our efforts have centered on two main interests: (1) understanding how Nature's ligand of choice, polypeptides, can be used to control the chemistry of nonbiological metal centers, and (2) mimicking metalloenzyme characteristics in designed, nonbiological catalysts. This Account conveys our motivation and goals for these studies, outlines progress to date, and discusses the future of enzyme-like catalyst design.In particular, these studies have resulted in on-bead, high-throughput screens for asymmetric metallopeptide catalysts. In addition, peptide-based molecular recognition strategies have facilitated the site-specific modification of protein substrates. Molecular recognition enables site-specific, proximity-driven modification of a broad range of amino acids, and the concepts outlined here are compatible with natural protein substrates and with complex, cell-like environments. We have also explored rhodium metallopeptides as hybrid organic-inorganic inhibitor molecules that block protein-protein interactions. © 2012 American Chemical Society.
