Examination of a 19th Century Daguerreotype Photograph using High Resolution Scanning Transmission Electron Microscopy for 2D and 3D Nanoscale Imaging and Analysis
نویسندگان
چکیده
In 1839, the daguerreotype photographic process was first presented to the scientific community in France. The technology spread rapidly and was widely used around the globe until roughly 1860. Image formation can be generalized into four steps: 1) exposing silver-plated copper to an iodine plus or minus another halogen vapor(s), 2) further exposing the sensitized plate to visible light within a camera, 3) development of an image after the plate is treated with heated mercury vapor, and 4) deposition of a gilding layer via gold chloride solution and heating [1].

Scanning precession electron tomography for three-dimensional nanoscale orientation imaging and crystallographic analysis
Three-dimensional (3D) reconstructions from electron tomography provide important morphological, compositional, optical and electro-magnetic information across a wide range of materials and devices. Precession electron diffraction, in combination with scanning transmission electron microscopy, can be used to elucidate the local orientation of crystalline materials. Here we show, using the examp...

High resolution nanoscale imaging in liquid environments is crucial for studying molecular interactions in biological and chemical systems. In particular, electron microscopy is the gold-standard tool for nanoscale imaging, but its high-vacuum requirements make application to in-liquid samples extremely challenging. Here we present a new graphene based wet cell device where high resolution scan...

Using a simple hydrothermal procedure and a subsequent annealing treatment, one-dimensional (1D) cobalt oxide nanowires (Co3O4-NWs) with tunable size have been successfully in situ fabricated on a three-dimensional (3D) carbon foam (CF) network. By changing the hydrothermal treatment time (0.5, 1, or 2 h) at 180 °C, size-controlled Co3O4 nanowires can be formed on the CF. Scanning electron micr...

The semiconductor industry has seen tremendous progress over the last few decades with continuous reduction in transistor size to improve device performance. Miniaturization of devices has led to changes in the dopants and dielectric layers incorporated. As the gradual shift from two-dimensional metal-oxide semiconductor field-effect transistor to three-dimensional (3D) field-effect transistors...

Nanoscale characterization of living samples has become essential for modern biology. Atomic force microscopy (AFM) creates topological images of fragile biological structures from biomolecules to living cells in aqueous environments. However, correlating nanoscale structure to biological function of specific proteins can be challenging. To this end we have built and characterized a correlated ...
