We have deposited aluminium oxide films by atomic layer deposition on titanium oxide nanoparticles in a fluidized bed reactor at 27 ± 3 °C and atmospheric pressure. Working at room temperature allows coating heat-sensitive materials, while working at atmospheric pressure would simplify the scale-up of this process. We performed 4, 7 and 15 cycles by dosing a predefined amount of precursors, i.e...

Recently, there has been a growing interest in point-of-care devices capable of detecting nucleic acids (NA) in clinical and environmental samples. Nucleic acid detection requires, however, various sample preparation steps that complicate device operation. An attractive remedy is to integrate many, if not all, sample preparation operations and nucleic acid amplification into a single reaction c...

A widely used application of the atomic layer deposition (ALD) and chemical vapour deposition (CVD) methods is the preparation of permeation barrier layers against water vapour. Especially in the field of organic electronics, these films are highly demanded as such devices are very sensitive to moisture and oxygen. In this work, multilayers of aluminium oxide (AlO x ) and plasma polymer (PP) we...

1. Plasma aluminium concentration and urinary aluminium excretion were monitored for 4.5 h in rats after the administration of 25 micrograms or 800 micrograms of aluminium as an intravenous bolus, either as aluminium chloride or as aluminium citrate (i.e. aluminium chloride together with sodium citrate). 2. Immediately after the bolus aluminium administration, the plasma aluminium concentration...

The present review deals with the recent progress made in field of electrochemical detection serotonin by means sensors based on various nanomaterials incorporated sensitive element. Due to unique chemical and physical properties these nanomaterials, it was possible develop excellent analytical performances, useful practice. main used are carbon electrodes modified nanotubes materials, such as ...

The purpose of this paper is to show the results of some work at the IRC in Materials for High Performance Applications at the University of Birmingham into the effect of processing and process parameters on the microstructure, macrostructure and chemistry of 100 mm diameter single plasma-melted ingots of a gamma-based titanium aluminide (Ti-48at%Al-2at%Mn-2at%Nb). The microstructure of the aqm...
