BACKGROUND The detection of biological and chemical species is of key importance to numerous areas of medical and life sciences. Therefore, a great interest exists in developing new, rapid, miniature, biocompatible and highly sensitive sensors, capable to operate under physiological conditions and displaying long-term stabilities (e.g. in-body implantable sensors). Silicon nanostructures, nanow...

Background: Mesenchymal stem cells (MSCs) are multipotent cells, capable of differentiating into different cell lines.They can sense their surrounding biochemical and biophysical factors, which play major roles in their differentiation toward different phenotypes. Therefore, the exposure of these cells to endothelial growth factor (VEGF) as well as hemodynamic biomechanical forces, which act on...

Abstract Boron-based two-dimensional materials are of interest for use in electronic devices and catalytic applications, which it is important that they chemically stable. Here, we explore the chemical stability hydrogen boride nanosheets water. Experiments reveal mixing water produces negligible amounts hydrogen, suggesting hydrolysis does not occur stable water, contrast to most boron hydride...

Silver films with a thickness below 50 nanometer were deposited on glass using DC magnetron sputtering. The chemical stability of the was investigated by exposure film to droplet HCl solution in humid atmosphere. affected area monitored digital microscope. increases approximately linearly time which points diffusive mechanism. slope versus plot, or diffusivity, measured as function acid concent...

Interface stability is a key factor for stable operation of electronic and electrochemical devices. This contribution introduces an approach the operando analysis interfaces using photoelectron spectroscopy employing solid oxide cell. The combined chemical information provided by experiment reveals that not only but also electrostatic boundary conditions are essential interface stability. demon...
