We have combined Piezoresponse Force Microscopy and Kelvin Probe Force Microscopy (KPFM) to study screening charge dynamics in written domains on PbZr0.2Ti0.8O3 (PZT) thin film surfaces under a controlled environment and at variable temperature. The screen ...
A multielectrode setup for protein OFFGEL electrophoresis that significantly improves protein separation efficiency has been developed. Here, the electric field is applied by segments between seven electrodes connected in series to six independent power su ...
Despite recent progress, Finite Element Analysis (FEA) of bone based on microCT imaging involves many manual steps and assumptions, being time consuming and error prone.As a consequence, these different modeling strategies may not necessary lead to the sam ...
Oil-in-water emulsions consist of oil droplets dispersed in an aqueous phase. Interfacial properties of the droplets determine the stability of emulsions. Even though this statement is widely accepted, a molecular level picture of the droplet interface is ...
Tunnel transport processes are considered in a square lattice of metallic nanogranules embedded into insulating host to model tunnel conduction in real metal/insulator granular layers. Based on a simple model with three possible charging states (+/- or 0) ...
The mass density of nanowires is determined using in situ resonance frequency experiments combined with quasi-static nanotensile tests. Our results reveal an average mass density of 7.36 g/cm3, which is below the theoretical density of bulk cobalt. The res ...
Adsorption of charged species at the interface between two immiscible electrolyte solutions (ITIES) is simulated taking into account both the mutual influence between the potential dependent surface excess charge and the potential distribution between the ...
A review. Activation of otherwise inert bonds has significant potential in the design of efficient and synthetically useful transformations. While general catalytic carbon-carbon single bond activations are still in their infancy, this emerging area examin ...
We established the charge and structure of the oil/water interface by combining ?-potential measurements, sum frequency scattering (SFS) and molecular dynamics simulations. The SFS experiments show that the orientation of water molecules can be followed on ...
On-column conductivity detection in capillary-chip electrophoresis was achieved by actively coupling the high electric field with two sensing electrodes connected to the main capillary channel through two side detection channels. The principle of this conc ...
