• (CVD) on Cu foils. Truly simultaneous operation is possible only with the use of small oscillation amplitudes. Under a typical STM imaging regime the force interaction is found to be repulsive. Force–distance spectroscopy revealed a maximum attractive force of about 7 nN between the tip and carbon

• array with maxima located in between the two carbon atoms was acquired in STM topography. Keywords: atomic force microscopy; CVD graphene; scanning tunneling microscopy; simultaneous operation; small amplitude; Introduction Graphene has been widely studied because of its potential use in future

• understood using simultaneous STM/AFM. Truly simultaneous operation is possible only with the use of sub-angstrom oscillation amplitudes. Simultaneous STM/AFM images of a graphene surface on a Cu substrate. (a) STM topography in constant-current mode (forward scan); (b) force in constant-current mode

• advantages of the two separated, up to now, research fields. For example, by integration with microfluidics technology, the simultaneous operation in both chemiresistor and SERS-based modes should readily become possible. We expect that this innovative type of dual sensor will combine and multiply the

• plastic flow of metallic glasses has been explained by the idea that a single shear band cannot accommodate the imposed strain rapidly enough at high strain rates [4]. According to the authors, at high strain rates the applied strain is instead accommodated by the simultaneous operation of multiple shear

• using the concept of “representative volume”, often invoked in analyses of transport phenomena in large systems (involving heat, mass and momentum transfer). The representative volume is assumed to be large enough to allow the operation of the unit processes relevant to a problem on hand. Simultaneous

• operation of these unit processes in different representative volumes that are present throughout the system and the summation of their effects is assumed to result in the overall response. Such an approach presupposes that the real problem is so complex that a rigorous analysis in all aspects is not
