Three-Dimensional Visualization and Characterization of Polymeric Self-Assemblies by Transmission Electron Microtomography

19-May-2017 | Hiroshi Jinnai; Takeshi Higuchi; Xiaodong Zhuge; Akihito Kumamoto; Kees Joost Batenburg; Yuichi Ikuhara, Accounts of Chemical Research, 2017

ConspectusSelf-assembling structures and their dynamical processes in polymeric systems have been investigated using three-dimensional transmission electron microscopy (3D-TEM). Block copolymers (BCPs) self-assemble into nanoscale periodic structures called microphase-separated structures, a deep ...

A novel scale‐down cell culture and imaging design for the mechanistic insight of cell colonisation within porous substrate

15-Mar-2017 | C.M. GABBOTT, Z.X. ZHOU, G.X. HAN, T. SUN, Journal of Microscopy, 2017

Summary At the core of translational challenges in tissue engineering is the mechanistic understanding of the underpinning biological processes and the complex relationships among components at different levels, which is a challenging task due to the limitations of current tissue culture and ...

The α‐β circular scanning with large range and low noise

15-Mar-2017 | J. LIU, X. YOU, Y. WANG, K. GU, C. LIU, J. TAN, Journal of Microscopy, 2017

Summary A circular‐route scanning method called α‐β circular scanning is proposed and realized using sinusoidal signals with a constant phase difference of π/2. Experiments show that the circular scanning range of α‐β circular scanning is 57% greater than the rectangular scanning range of ...

Atom-by-Atom Construction of a Quantum Device

10-Mar-2017 | Jason R. Petta, ACS Nano, 2017

Scanning tunneling microscopes (STMs) are conventionally used to probe surfaces with atomic resolution. Recent advances in STM include tunneling from spin-polarized and superconducting tips, time-domain spectroscopy, and the fabrication of atomically precise Si nanoelectronics. In this issue of ...

Advanced digital image analysis method dedicated to the characterization of the morphology of filamentous fungus

06-Feb-2017 | N. HARDY, M. MOREAUD, D. GUILLAUME, F. AUGIER, A. NIENOW, C. BÉAL, F. BEN CHAABANE, Journal of Microscopy, 2017

Summary Filamentous fungi have a complex morphology that induces fermentation process development issues, as a consequence of viscosity increase and diffusion limitations. In order to better understand the relationship between viscosity changes and fungus morphology during fermentations of ...

Three‐Phase Segmentation of Solid Oxide Fuel Cell Anode Materials Using Lab Based X‐ray Nano‐Computed Tomography

02-Feb-2017 | T. M. M. Heenan, J. J. Bailey, X. Lu, J. B. Robinson, F. Iacoviello, D. P. Finegan, D. J. L. Brett, P. R. Shearing, Fuel Cells, 2017

Abstract Triple‐phase boundaries are an important microstructural metric to assess the performance and durability of solid oxide fuel cell electrodes and are known to significantly influence the performance at cell level. In recent years many advancements have been made in the quantification ...

Three-Dimensional Localization of Single Molecules for Super-Resolution Imaging and Single-Particle Tracking

02-Feb-2017 | Alex von Diezmann; Yoav Shechtman; W. E. Moerner, Chemical Reviews, 2017

Single-molecule super-resolution fluorescence microscopy and single-particle tracking are two imaging modalities that illuminate the properties of cells and materials on spatial scales down to tens of nanometers or with dynamical information about nanoscale particle motion in the millisecond ...

A systematic investigation of the charging effect in scanning electron microscopy for metal nanostructures on insulating substrates

02-Dec-2016 | R. FLATABØ, A. COSTE, M. M. GREVE, Journal of Microscopy, 2016

Summary Scanning electron microscopy is perhaps the most important method for investigating and characterizing nanostructures. A well‐known challenge in scanning electron microscopy is the investigation of insulating materials. As insulating materials do not provide a path to ground they ...

CuI heterogenized on thiosemicarbazide modified‐multi walled carbon nanotubes (thiosemicarbazide‐MWCNTs‐CuI): Novel heterogeneous and reusable nanocatalyst in the C‐N Ullmann coupling reactions

02-Dec-2016 | Hojat Veisi, Yalda Metghalchi, Malak Hekmati, Shiva Samadzadeh, Applied Organometallic Chemistry, 2016

Herein we described the synthesis of novel thiosemicarbazide‐MWCNTs‐CuI nanocatalyst by covalent grafting of thiosemicarbazide on carbon nanotubes surface and subsequent coordination with CuI catalyst. The formation of nanocatalyst was analyzed by Raman spectroscopy, energy dispersive ...
