Highly efficient reduction of bromate to bromide over mono and bimetallic ZSM5 catalysts

The reduction of bromate to bromide was successfully catalyzed by mono and bimetallic catalysts based on ZSM5 zeolites. This reaction is important since the presence of bromate in water is potentially carcinogenic to humans. The catalysts were prepared by ion-exchange and incipient wetness ... more

Relaxation dynamics of liposomes in an aqueous solution

The gel–liquid crystal phase transition has been studied by the temperature and frequency dependent dielectric relaxation behavior of liposomes in an aqueous solution (40 g L−1 DPPC–water mixture). Four relaxation processes were observed in the frequency range from 40 Hz to 30 GHz which wer ... more

Films of bacteria at interfaces: three stages of behaviour

We report an investigation of the formation of films by bacteria at an oil-water interface using a combination of particle tracking and pendant drop elastometry. The films display a remarkably varied series of dynamical and mechanical properties as they evolve over the course of minutes to ... more

Tandem ICP – Mass Spectrometry for Sr Isotopic Analysis without Prior Rb/Sr Separation

The use of a mixture of 10% of CH3F and 90% of He as a reaction gas in tandem ICP – mass spectrometry (ICP-MS/MS) enables the accurate determination of the 87Sr/86Sr isotope ratio in geological materials, provided that mass discrimination is corrected for by using a combination of internal ... more

High-precision Fe isotopic analysis of whole blood for biomedical purposes without prior isolation of the target element

Recently, it has been documented that Fe isotopic analysis of whole blood and serum by means of multi-collector ICP-mass spectrometry (MC-ICP-MS) is providing promising results in a biomedical context and thus, there is a demand for simple, fast and reliable methodologies, providing high sa ... more

Research highlights: surface-based microfluidic control

Microfluidic systems are often dominated by their surfaces because of the high surface area to volume ratios in microchannel flows or drop-based systems. Here we highlight recent work on engineering and exploiting surface effects to control the formation and motion of microdrops. We highlig ... more

Development and Validation of a Microfluidic Immunoassay Capable of Multiplexing Parallel Samples in Microliters Volumes

Immunoassays are widely utilized due to their ability to quantify a vast assortment of biomolecules relevant to biological research and clinical diagnostics. Recently, immunoassay capabilities have been improved by the development of multiplex assays that simultaneously measure multiple ana ... more

Direct Determination of Lead in Plastic Toys by Solid Sampling High Resolution-Continuum Source Graphite Furnace Atomic Absorption Spectrometry

In this study, lead concentrations in various plastic toys were determined directly by solid sampling high resolution continuum source graphite furnace atomic absorption spectrometry. The toys were cut into small pieces and introduced into the graphite furnace between 0.05 and 0.7 mg withou ... more

Formation, compression and surface melting of colloidal clusters by active particles

We demonstrate with experiments and numerical simulations that the structure and dynamics of a suspension of passive particles is strongly altered by adding a very small ($< 1\%$) number of active particles. With increasing passive particle density, we observe first the formation of dynamic ... more

Small polyanion recognition of triazolium cyclodextrin click cluster in water

In order to detect small polyanions (sPAs), which play important roles in many biological systems, a triazolium cyclodextrin click cluster (5, hexakis{6-(3-methyl-4-hydroxymethyl-1H-1,2,3-triazolium-1-yl)-6-deoxy}-α-cyclodextrin iodide) was synthesized and characterized. The competition bin ... more

A method for barrier‐based incident investigation

Incident investigation is a formal requirement for high hazard facilities with the aim to learn from each incident and to prevent future recurrences. There are many published investigation methods, with most driving to the management system root cause and some applying newer barrier‐based m ... more

Continuously Conducted Selective Hydrogenation of Benzene to Cyclohexene in a Four‐Phase System

Abstract Currently, the production of nylon 6 and nylon 6.6 is based on the complete hydrogenation of benzene to cyclohexane over nickel or platinum catalysts and its subsequent oxidation at very low conversions to a mixture of cyclohexanol/cyclohexanone. This mixture is further reacted ... more
