Thin Au films (~5 nm) are known to form island-like structures with small gaps between the islands, which produce intense electric field "hot spots" under visible illumination. In this work, we perform finite difference time domain (FDTD) simulations based on experimentally observed high resolution transmission electron microscope (HRTEM) images of these films in order to study the nature of th...

A microcomputer controlled scanning stage has been developed which greatly facilitates track counting. It has been designed specifically for the external detector method of fission-track dating, although the basic hardware could be used for a variety of different scanning requirements. With this system, the microscope stage is automatically controlled to move between corresponding points on the...

In this paper, we develop nonlinear constitutive equations and resulting system models quantifying the nonlinear and hysteretic field-displacement relations inherent to lead zirconate titanate (PZT) devices employed in atomic force microscope stage mechanisms. We focus specifically on PZT rods utilizing d33 motion and PZT shells driven in d31 regimes, but the modeling framework is sufficiently ...

This paper explores a new application of structured illumination to determine the position of a microscope stage. Measuring stage position accurately is important for any experiment that spans multiple fields of view. The structured illumination pattern is provided by a design printed on the microscope slide or cover slip that modulates the image of the specimen. A novel application of frequenc...

Designing carbon-based non-precious metal hybrid materials to replace precious catalysts solve environmental pollution problems is a hot topic of research at this stage. In work, dual ligand Cu-MOF was synthesized by the solvothermal method and using as sacrificial template further vulcanized obtain Cu 1.96 S/NSC material. The morphology composition material were investigated scanning electron ...

The innovative hot stamping press of quenchable steel mainly includes two stages: hot forming of blank at elevated temperature and quenching of hot stamped part in closed water-cooled tools. Crucial stage in hot stamping process is quenching of hot formed part in water-cooled tool to achieve final high ultimate tensile strength. In quenching stage, cooling rate of hot stamped part has a signifi...
