This study reports the effect of deposition time on the electrochemical, structural, morphological and optical properties of Cu 2 O thin films electrodeposited on ITO

In addition, as far as the authors are aware of, the influence of pH on the denaturation extent, the surface chemical composition, the water sorption isotherm, and the glass

In the case of titrations starting from acidic, alkaline and neutral pH, it is also possible to evaluate the number of protons bound to the surface of the particle by comparing the pH

Although the HDPE nets could not be directly treated by PICVD, this simulated behaviour demonstrates that, if the UV pro- tector issue can be curtailed, a 120° contact angle should

There was no stiffness increment for control tumors non-injected with CNTs and irradiated at the laser set-up of thermal ablation or mild hyperthermia considering the time

We show that the properties of superparamagnetic iron oxide nanoparticles suspended in liquids can be effectively studied using Magnetic Circular Dichroism in

Two cases are then considered: In assessment B1a, the smooth CGA-CGO concentration difference is applied to all CSIRO sites, while at CMDL sites zero values are used.. Conversely,

En utilisant l’idée de Selberg pour estimer π k (x), l’étude directe de la série génératrice adéquate nous permet aussi de démontrer le théorème suivant, qui localise le
