Strain-relief pattern as guide for the formation of surface-supported bimolecular nanoribbons

We demonstrate the suitability of the Ag/Pt(111) strain-relief pattern as efficient template for controlling the formation of well defined heteromolecular nanostructures. Two different species of molecular building blocks with complementary end-group funct ...

Three-Phase Catalytic Hydrogenation of a Functionalized Alkyne: Mass Transfer and Kinetic Studies with in Situ Hydrogen Monitoring

Albert Renken, Lioubov Kiwi, Martin Grasemann

Systematic studies of mass transfer interactions with intrinsic reaction kinetics were performed for the threephase selective hydrogenation of 2-methyl-3-butyn-2-ol (MBY) to 2-methyl-3-buten-2-ol (MBE) over a modified Pd/CaC

Pd Nanoparticles in a Supported Ionic Liquid Phase: Highly Stable Catalysts for Selective Acetylene Hydrogenation under Continuous-Flow Conditions

Paul Joseph Dyson, Lioubov Kiwi, Gabor Laurenczy, Marina Ruta

Monodispersed Pd nanoparticles of 5 and 10 nm were obtained via reduction of Pd(acac)2 dissolved in ionic liquid (IL), [bmim][PF6], or [bmimOH][TF2N], supported on carbon nanofibers (CNF) anchored to sintered metal fibers (SMF). Using [bmimOH][TF2N], the m ...

Fast temperature cycling of the catalytic CO oxidation using microstructure reactors

Martin Luther

The possibility to increase the performance (productivity or selectivity) of a chemical reactor by using periodic variations of reaction parameters (e.g. reactant concentration or temperature) has been theoretically envisaged since the beginning of the 70t ...

Uncertainties in kinetic hard-modelling of multivariate spectroscopic data

Julien Léo Billeter, Konrad Hungerbühler

Kinetic hard-modelling of multivariate spectroscopic data [1, 2] is a well-established method for the determination of reaction mechanisms and associated rate constants. Kinetic hard-modelling relies on a hard model defined by kinetic rate laws and require ...

Online optimisation and detection of process upset in semi-batch reactors using a kinetic modelling approach

Julien Léo Billeter, Konrad Hungerbühler

Process Analytical Chemistry/Technology has tremendously evolved in the last decades due to the development of multivariate online sensors that are able to monitor the properties of industrial processes in real time [1, 2]. Online monitoring of product qua ...

Uncertainties and error propagation in kinetic hard-modelling of spectroscopic data

Julien Léo Billeter, Konrad Hungerbühler

A novel method is presented for the rigorous propagation of uncertainties in initial concentrations and in dosing rates into the errors in the rate constants fitted by multivariate kinetic hard-modelling of spectroscopic data using the Newton–Gauss–Levenbe ...

Mechanism for the Substitution of an Aqua Ligand of UO2(OH2)(5)(2+) by Chloride

François Rotzinger

Geometry and energy of the reactant (UO2(OH2)(5)center dot Cl+), the transition state (UO2(OH2)(5)center dot center dot center dot Cl+ double dagger), and the product (UO2Cl(OH2)(4)center dot OH2+) of the title reaction have been computed with complete act ...

Automatic detection of reaction start/endpoints in chemical and biotechnological reaction systems

Simon Crelier, Michael Amrhein

A classification methodology for the automatic detection of start- and endpoints of chemical and biotechnological reaction systems from spectral reaction data is proposed. In the calibration phase, several batch experiments must be conducted covering the e ...

Synthesis of monodispersed palladium nanoparticles to study structure sensitivity of solvent-free selective hydrogenation of 2-methyl-3-butyn-2-ol

Albert Renken, Lioubov Kiwi, Danièle Laub

A novel method for isolation of monodispersed Pd nanoparticles from a reverse microemulsion was developed using hydrocarbon evaporation and methanol-assisted particle purification from a surfactant. Fcc Pd nanoparticles of 6, 8, 11, and 13 nm in diameter w ...
