Ultraslow waves on the nanoscale

20-Oct-2017 | Kosmas L. Tsakmakidis; Ortwin Hess; Robert W. Boyd; Xiang Zhang, Science , 2017

There has recently been a surge of interest in the physics and applications of broadband ultraslow waves in nanoscale structures operating below the diffraction limit. They range from light waves or surface plasmons in nanoplasmonic devices to sound waves in acoustic-metamaterial waveguides, as ...

High-Speed “4D” Computational Microscopy of Bacterial Surface Motility

01-Sep-2017 | Jaime de Anda; Ernest Y. Lee; Calvin K. Lee; Rachel R. Bennett; Xiang Ji; Soheil Soltani; Mark C. Harrison; Amy E. B ..., ACS Nano, 2017

Bacteria exhibit surface motility modes that play pivotal roles in early-stage biofilm community development, such as type IV pili-driven “twitching” motility and flagellum-driven “spinning” and “swarming” motility. Appendage-driven motility is controlled by molecular motors, and analysis of ...

Analysis of liquid suspensions using scanning electron microscopy in transmission: estimation of the water film thickness using Monte–Carlo simulations

22-Aug-2017 | J. XIAO, G. FORAY, K. MASENELLI‐VARLOT, Journal of Microscopy, 2017

Summary Environmental scanning electron microscopy (ESEM) allows the observation of liquids under specific conditions of pressure and temperature. Moreover, when working in the transmission mode, that is in scanning transmission electron microscopy (STEM), nano‐objects can be analysed inside a ...

The structure and ultrastructure of the egg capsules of stoneflies of the genus Isoperla (Insecta, Plecoptera, Perlodidae)

17-Aug-2017 | Anna Michalik, Marko Miliša, Katarzyna Michalik, Elżbieta Rościszewska, Microscopy Research and Technique, 2017

Abstract The egg capsules of five systellognathan stoneflies species representing the genus Isoperla (Plecoptera, Perlodidae) have been investigated using light and electron microscopes (SEM and TEM). We consider the structural modifications of egg coverings (egg capsules, eggshells) like: a ...

Frontispiece: High‐Throughput Optical Imaging and Spectroscopy of One‐Dimensional Materials

21-Jul-2017 | Fengrui Yao, Cheng Chen, Can Liu, Jin Zhang, Feng Wang, Kaihui Liu, Chemistry - A European Journal, 2017

Conventionally, the optical signal of individual carbon nanotubes (CNTs) is usually too weak to be probed under optical microscopes. By using a homodyne detection method, scattered light wave from the individual CNTs (ENT) interferes with the reference light (Eref), the intensity of carbon ...

Enhancing image contrast of carbon nanotubes on cellular background using helium ion microscope by varying helium ion fluence

13-Jul-2017 | M.M. DYKAS, K. PODDAR, S.L. YOONG, V. VISWANATHAN, S. MATHEW, A. PATRA, S. SAHA, G. PASTORIN, T. VENKATESAN, Journal of Microscopy, 2017

Summary Carbon nanotubes (CNTs) have become an important nano entity for biomedical applications. Conventional methods of their imaging, often cannot be applied in biological samples due to an inadequate spatial resolution or poor contrast between the CNTs and the biological sample. Here we ...
