On-site biological hand washing water treatment can improve global access to safe hand washing water, but requires a thorough understanding of the chemical composition of the water to be treated, and an effective treatment strategy. This study first presen ...
Simultaneous washing and concentration of functionalized magnetic beads in a complex sample solution was demonstrated by applying a rotational magnetic actuation system to a microfluidic chip under continuous flow conditions. The rotation of periodically a ...
After the spread of COVID-19, surgical masks became highly recommended to the public. They tend to be handled and used multiple times, which may impact their performance. To evaluate this risk, surgical masks of Type IIR were submitted to four simulated tr ...
We present a novel, simple and highly efficient protocol for the extraction of magnetic particles out of individual droplets on a digital lab-on-chip in the presence of a spatially fixed magnet with a permanent magnetic field. In this approach, the particl ...
Simultaneous sample washing and concentration of two waterborne pathogen samples were demonstrated using a rotational magnetic system under continuous flow conditions. The rotation of periodically arranged small permanent magnets close to a fluidic channel ...
A solution phase combinatorial synthesis of aryl piperazines 1 and 2 is described based on the S(N)Ar reaction and Schotten-Baumann acylation. The use of excess reagent is allowed and pure arylpiperazines 1 and 2 were obtained by simple acid/base washing. ...
The antistatic and hydrophilic properties of acrylic, polyamide, and polyester fibers were improved by treatment with a polymerizable vinyl monomer contg. an ammonium group and a polymerizable monomer contg. a carboxyl or sulfo group and irradiating. Thus, ...

Simultaneous washing and concentration of magnetic microparticles was demonstrated using a rotational magnetic system under a continuous-flow condition. The rotation of periodically arranged permanent magnets close to a fluidic channel carrying a suspensio ...
Purification of magnetic microparticles was demonstrated, with a purification efficiency of (72±14) % at a flow rate of 3 μl/min, in a microfluidic chip using a rotational magnetic system under continuous flow conditions. The rotation of a periodically arr ...
Adsorption of N-2 at 77 K and scanning electron microscopy have been used to measure the changes in the support morphology, at nano- and microscale level, along the processes involved in the preparation of a supported Pd catalyst: Pd deposition, doping, an ...
