Hydrodynamics of orbital shaken bioreactors

Be it to aerate a glass of wine before tasting, to accelerate a chemical reaction or to cultivate cells in suspension, the “swirling” (or orbital shaking) of a container ensures good mixing and gas exchange in a simple and intuitive way. Despite being used ...

Structural cluster analysis of chemical reactions in solution

Fabio Pietrucci

We introduce a simple and general approach to the problem of clustering structures from atomic trajectories of chemical reactions in solution. By considering distance metrics which are invariant under permutation of identical atoms or molecules, we demonst ...

Quantum state-resolved gas/surface reaction dynamics probed by reflection absorption infrared spectroscopy

Rainer Beck, Li Chen, Régis Bisson, Hirokazu Ueta

We report the design and characterization of a new molecular-beam/surface-science apparatus for quantum state-resolved studies of gas/surface reaction dynamics combining optical state-specific reactant preparation in a molecular beam by rapid adiabatic pas ...

Chemistry of Doped Colloidal Nanocrystals

Raffaella Buonsanti

Review. Synthetic control over inorg. nanocrystals has made dramatic strides so that a great no. of binary and a few ternary or more complex compds. can now be prepd. with good control over size and phys. properties. Recently, chemists have tackled the lon ...

A selective chemiluminescence detection method for reactive oxygen species involved in oxygen reduction reaction on electrocatalytic materials

Christos Comninellis, Pauline Bornoz

An original selective and quantitative detection method for direct access to reactive oxygen species (ROS) generated in near-neutral aqueous solutions during transient electrochemical experiments is described herein. Several chemiluminescent probes, which ...

Cell Polarization: Mechanical Switch for a Chemical Reaction

Anterior-posterior polarity in the Caenorhabditis elegans zygote depends on two groups of PAR proteins, as well as on cortical flow. Recent work now demonstrates that this polarization results from a transition in a bistable reaction-diffusion system of PA ...

Sequential N–O and N–N Bond Cleavage of N-Heterocyclic Carbene-Activated Nitrous Oxide with a Vanadium Complex

Rosario Scopelliti, Kay Severin, Matthew Wodrich, Euro Solari, Alexander Tskhovrebov

Chemically induced bond cleavage of nitrous oxide typically proceeds by rupture of the N–O bond with concomitant O-atom transfer and liberation of dinitrogen. On a few occasions, N–N bond scission has been observed instead. We report a reaction sequence in ...

Observation of Oscillatory Surface Reactions of Riboflavin, Trolox, and Singlet Oxygen Using Single Carbon Nanotube Fluorescence Spectroscopy

Ardemis Anoush Boghossian

Single-mol. fluorescent microscopy allows semiconducting single-walled carbon nanotubes (SWCNTs) to detect the adsorption and desorption of single adsorbate mols. as a stochastic modulation of emission intensity. In this study, we identify and assign the s ...

Boosted Hybrid Method for Solving Chemical Reaction Systems with Multiple Scales in Time and Population Size

Assyr Abdulle

A new algorithm, called boosted hybrid method, is proposed for the simulation of chemical reaction systems with scale-separation in time and disparity in species population. For such stiff systems, the algorithm can automatically identify scale-separation ...

Indole Alkaloids Synthesis via a Selective Cyclization of Aminocyclopropanes

Jérôme Waser, Filippo De Simone

The continuous progress in medicinal chemistry requires more versatile synthetic strategies for the generation of large libraries of active compounds and their analogues. As a result, the research for new effective cyclization and cycloaddition reactions i ...
