Facile Synthesis of Gold Icosahedra in an Aqueous Solution by Reacting HAuCl4 with N‐Vinyl Pyrrolidone
Authors: Yavuz Mustafa S. , Li Weiyang , Xia Younan 
Published: October 2009

AbstractHerein we describe a protocol that generates Au icosahedra in high yields by simply mixing aqueous solutions of HAuCl4 and N‐vinyl pyrrolidone. Our mechanistic study reveals that water plays an important role in this synthesis: as a nucleophile, it attacks the gold–vinyl complex, leading to the production of an alcohol‐based AuI intermediate. This intermediate then undergoes a redox reaction in which AuI is reduced to Au0, leading to the formation of Au atoms and then Au icosahedra of about 18 nm in size at a yield of 94 %, together with a carboxylic acid in the final product. This new protocol has also been employed to prepare multiply twinned nanoparticles of Ag (15–20 nm in size), spherical aggregates (25–30 nm in size) of Pd nanoparticles, and very small nanoparticles of Pt (2 nm in size). Since no organic solvent, surfactant, or polymer stabilizer is needed for all these syntheses, this protocol may provide a simple, versatile, and environmentally benign route to noble‐metal nanoparticles having various compositions and morphologies.
Direct Comparison of the Reactivity of Model Complexes for Compounds 0, I, and II in Oxygenation, Hydrogen‐Abstraction, and Hydride‐Transfer Processes

Published: October 2009

AbstractThe iron(III) meso‐tetramesitylporphyrin complex is a good biomimetic to study the catalytic reactions of cytochrome P450. All of the three most discussed reactive intermediates concerning P450 catalysis (namely, Cpd 0, Cpd I, and Cpd II) can be selectively produced, identified, and stabilized for many minutes in solution at low temperature by choosing appropriate reaction conditions. In this way, their reactivity against various substrates was determined by utilizing low‐temperature rapid‐scan UV/Vis spectroscopy. Since all reactive intermediates are derived from a single model complex, the results of these kinetic measurements provide for the first time a full comparability of the determined rate constants for the three intermediates. The rate constants reveal a significant dependence of the reactivity on the type of reaction (e.g., oxygenation, hydrogen abstraction, or hydride transfer), which closely correlates with the chemical nature of Cpds 0, I, and II. The detailed knowledge of the reactivity of these intermediates provides a valuable tool to evaluate their particular role in biological systems.

AbstractBesides undesirable changes in the attractive aroma, a significant decrease in the intensity of the bitterness as well as a change of the taste into a lingering, harsh bitterness has long been known as a shelf‐life limiting factor of beer. Multiple studies have demonstrated that the aging of beer induces a decrease of the total amount of cis‐ and trans‐iso‐α‐acids, the well‐known bitter principles of beer. Although the trans‐iso‐α‐acids exclusively, not the cis‐iso‐α‐acids, were found to be degraded upon storage of beer, the key transformation products formed exclusively from the trans isomers in beer are not known. In the present study, suitable model experiments followed by LC–MS/MS and sophisticated NMR spectroscopic experiments, including the measurement of residual dipolar couplings (RDCs) in gel‐based alignment media as well as a novel broadband and B1‐field‐compensated incredible natural abundance double‐quantum transfer experiment (INADEQUATE) pulse sequence, enabled the identification of a series of previously unknown trans‐specific iso‐α‐acid transformation products, namely, tricyclocohumol, tricyclocohumene, isotricyclocohumene, tetracyclocohumol, and epitetracyclocohumol, respectively. HPLC–MS/MS analysis of these compounds, which exhibit the aforementioned harsh lingering bitter taste and have threshold concentrations ranging from 5 to 70 μmol L−1, confirmed their generation during aging of beer and, for the first time, explained the storage‐induced changes of the beer’s bitter taste on a molecular level.
Biofuel Cells Controlled by Logically Processed Biochemical Signals: Towards Physiologically Regulated Bioelectronic Devices
Authors: Katz Evgeny , Pita Marcos 
Published: October 2009

AbstractBiofuel cells with a switchable power release controlled by biochemical signals, which can be logically processed by biomolecular computing systems, have been designed. The switchable properties of the biofuel cells were based on the polymer‐brush‐modified electrodes with the activity dependent on the solution pH value. The pH changes generated in situ by biocatalytic reactions allowed the reversible activation—inactivation of the bioelectrocatalytic interfaces—thus affecting the activity of the entire biofuel cells. Boolean logic operations performed by either enzyme‐ or immune‐based systems were functionally integrated with the switchable biocatalytic process allowing logic control over them. Scaling up the complexity of the biocomputing systems to complex multi‐component logic networks with a built‐in “program” resulted in the control of the bioelectronic systems by multi‐signal patterns of biochemical inputs. Future implantable biofuel cells producing electrical power on‐demand depending on physiological conditions are feasible, as the result of the present research.
