in this research, polyvinylchloride based composite heterogeneous cation exchange membranes were prepared by the solution casting technique. chitosan-co-iron nickel oxide nanoparticles were utilized as membrane surface modifier to improve the membranes electrochemical properties. the effect of additive nanoparticle concentration in the modifier solution on the properties of composite membranes ...

Uptake (or negative flux) of nitrous oxide (N2O) in agricultural soils is a controversial issue which has proved difficult to investigate in the past due to constraints such as instrumental precision and methodological uncertainties. Using a recently developed high-precision quantum cascade laser gas analyser combined with a closed dynamic chamber, a well-defined detection limit of 4 μg N2O-N m...

Good-quality silicon dioxide films have been deposited at low temperature (≤200 °C) using continuous and pulsed oxygen/silane plasmas coupled in a high-density, low-pressure helicon reactor. Although the total ion flux determines many of the structural properties of the deposited oxide, we have found that silicon-containing ions contribute to the film growth (up to 50 %) and appear to be respon...

Anodic aluminum oxide templates containing extended arrays of holes with 30-nm diameter and approximately 128-nm spacing were sputter-coated with Nb. We find pronounced matching effects in the transport and magnetization measurements beyond 4 kOe. In addition, we observe Little–Parks oscillations of the superconducting critical temperature. We compare the flux pinning in the patterned samples t...

We were interested to read the paper by LEHTIMÄKI et al. [1] recently published in the European Respiratory Journal, in which those authors reported that ‘‘high pre-treatment levels of J9aw,NO [bronchial nitric oxide flux] are related to symptom relief and improvement of airway obstruction’’ when inhaled fluticasone is given to patients with chronic obstructive pulmonary disease (COPD). Their d...

A memristor is a two-terminal electronic device whose conductance can be precisely modulated by charge or flux through it. Here we experimentally demonstrate a nanoscale silicon-based memristor device and show that a hybrid system composed of complementary metal-oxide semiconductor neurons and memristor synapses can support important synaptic functions such as spike timing dependent plasticity....

We present the results of a magnetoresistance study of the disorder-induced superconductor-insulator transition in an amorphous indium-oxide thin film patterned by a nanoscale periodic array of holes. We observed Little-Parks-like oscillations over our entire range of disorder spanning the transition. The period of oscillations was unchanged and corresponded to the superconducting flux quantum ...
