Using state of the art scanning transmission electron microscopy (STEM) it is nowadays possible to directly image single atomic columns at sub-Å resolution. In standard (high angle) annular dark field STEM ((HA)ADF-STEM), however, light elements are usually invisible when imaged together with heavier in one image. Here we demonstrate capability recently introduced Integrated Differential Phase Contrast (iDPC-STEM) technique both and heavy atoms a thin sample We use resolve Gallium Nitrogen...

In electron cryomicroscopy (cryo-EM), molecular images of vitrified biological samples are obtained by conventional transmission microscopy (CTEM) using large underfocuses and subsequently computationally combined into a high-resolution three-dimensional structure. Here, we apply scanning (STEM) the integrated differential phase contrast mode also known as iDPC-STEM to two cryo-EM test specimens, keyhole limpet hemocyanin (KLH) tobacco mosaic virus (TMV). The micrographs show complete...
The structures and molecular packing of tribromo- triiodomesitylene are reported compared to that trichloromesitylene. Attractive triangular X3 interactions dominate the in all three structures. nonspherical atomic charge distribution on halogens results formation donor−acceptor which each halogen atom is simultaneously a donor an acceptor.

A Monte Carlo tool is presented for the simulation of secondary electron (SE) emission in a scanning microscope (SEM). The based on Geant4 platform CERN. modularity this makes it comparatively easy to add and test individual physical models. Our aim has been develop flexible generally applicable tool, while at same time including good description low-energy (<50 eV) interactions electrons with matter. To end we have combined Mott cross-sections phonon-scattering elastic scattering electrons,...

This paper describes the use of a Monte Carlo model incorporating finite-element method computing electrostatic fields inside and outside semiconductor, plus ray-tracing algorithm for determining doping contrast observed in scanning electron microscope (SEM). combined numerical also enables effects on surface band-bending to be distinguished from those external patch specimen, as well any applied macroscopic detection system SEM. Good agreement our new theory with experiment is obtained. The...
The formation of a series polymeric isostructural solids that utilize 1,4-diiodoperchlorobenzene (C6I2Cl4) as halogen bond donor has been achieved. These cocrystals are based upon C6I2Cl4 along with one three isosteric bipyridines, namely, trans-1,2-bis(4-pyridyl)ethylene (BPE), 4,4′-azopyridine (AP), or 1,2-bis(4-pyridyl)acetylene (BPA). In all cases, one-dimensional chain is formed held together by I···N bonds in which molecules stack homogeneous face-to-face π–π stacking orientation. As...
Control over thermal expansion (TE) behaviors in solid materials is often accomplished by modifying the molecules or intermolecular interactions within solid. Here, we use a mixed cocrystal approach and incorporate with similar chemical structures, but distinct functionalities. Development of cocrystals at nascent stage, here describe first sustained one-dimensional halogen bonds. Within each cocrystal, halogen-bond donor fixed, while acceptor site contains two variable ratio. X-ray...
