Continuous Production of Tailored Silver Nanoparticles by Polyol Synthesis and Reaction Yield Measured by X-ray Absorption Spectroscopy: Toward a Growth Mechanism

Christian Ludwig, Heinrich Hofmann, Paul Bowen, Frank Nüesch, Andrea Testino, Jose Enrico Quijano Quinsaat

Two complementary topics are discussed: (i) the continuous production of silver nanoparticles (AgNPs) and (ii) the measurement of reaction yield by X-ray absorption near-edge spectroscopy (XANES). The continuous polyol synthesis of AgNPs in grams amount an ...

Multilevel Correlations in the Biological Phosphorus Removal Process: from Bacterial Enrichment to Conductivity-Based Metabolic Batch Tests and Polyphosphatase Assays

Christof Holliger, Julien Maillard, Alessandro Brovelli, David Gregory Weissbrodt, Alexandre Chabrelie, Jonathan May

Enhanced biological phosphorus removal (EBPR) from wastewater relies on the preferential selection of active polyphosphate-accumulating organisms (PAO) in the underlying bacterial community continuum. Efficient management of the bacterial resource requires ...

A dose-response strategy reveals differences between normal-weight and obese men in their metabolic and inflammatory responses to a high-fat meal

Martinus Gijs, Guy Vergères, Flurina Schwander, Reto Portmann

A dose-response strategy may not only allow investigation of the impact of foods and nutrients on human health but may also reveal differences in the response of individuals to food ingestion based on their metabolic health status. In a randomized crossove ...

Coating of open cell foams

Kumar Varoon Agrawal, Han Zhang

The interior surfaces of three-dimensional open cell foams were coated by a combination of dip coating and spin coating. Glycerol/water solutions were used as model Newtonian liquids, and the coating processes were studied on open cell carbon foams with 10 ...

Calorie Restriction-like Effects of 30 Days of Resveratrol Supplementation on Energy Metabolism and Metabolic Profile in Obese Humans

Johan Auwerx, Richardus Houtkooper, Dongryeol Ryu

Resveratrol is a natural compound that affects energy metabolism and mitochondrial function and serves as a calorie restriction mimetic, at least in animal models of obesity. Here, we treated 11 healthy, obese men with placebo and 150 mg/day resveratrol (r ...

"Functional Poly(ethylene glycol)": PEG-Based Random Copolymers with 1,2-Diol Side Chains and Terminal Amino Functionality

Frederik Roman Wurm

A series of poly(ethylene glycol-co-isopropylidene glyceryl glycidyl ether) (P(EO-co-IGG)) random copolymers with different fractions of 1,2-isopropylidene glyceryl glycidyl ether (IGG) units was synthesized. After acidic hydrolysis a new type of "function ...

Automated characterization of dextran/concanavalin A mixtures-A study of sensitivity and temperature dependence at low viscosity as basis for an implantable glucose sensor

Peter Ryser, Eric Meurville

Mixtures of aqueous solutions of dextran and concanavalin A have a potential use as glucose sensing substances. We investigate these mixtures at low viscosities which are especially advantageous for miniature mechanical glucose sensing devices. The glucose ...

Invertible Enantioselectivity in 6'-Deoxy-6'-acylamino-beta -isocupreidine-Catalyzed Asymmetric Aza-Morita-Baylis-Hillman Reaction: Key Role of Achiral Additive

Jieping Zhu

The beta -isocupreidine (beta -ICD) or beta -ICD-amide (I)-catalyzed aza-Morita-Baylis-Hillman reaction between N-sulfonylimines and alkyl vinyl ketones produced the (R)-enriched adducts, e.g. II. By adding a catalytic amt. of beta -naphthol, the enantiose ...

Dynamic nuclear polarization of small labelled molecules in frozen water-alcohol solutions

Arnaud Comment, Sami Jannin, Jacques Van Der Klink, Fiodar Kurdzesau

In recent years methods of creating 'hyperpolarized' substances have gained considerable attention in biomedical magnetic resonance and dynamic nuclear polarization (DNP) is one of the most promising, especially for imaging applications. Here we present re ...

Quantitative characterization of a recombinant Pichia pastoris Mut+ strain secreting avidin using transient continuous cultures

Carmen Jungo

The objective of this thesis was to characterize the growth stoichiometry, the specific recombinant protein productivity and the regulation of the alcohol oxidase (AOX) enzyme of a Pichia pastoris Mut+ strain, performing conventional chemostat cultures and ...
