Time-Dependent Density Functional Theory for Open Systems and Its Applications

19-Jan-2018 | Shuguang Chen; YanHo Kwok; GuanHua Chen, Accounts of Chemical Research, 2018

ConspectusPhotovoltaic devices, electrochemical cells, catalysis processes, light emitting diodes, scanning tunneling microscopes, molecular electronics, and related devices have one thing in common: open quantum systems where energy and matter are not conserved. Traditionally quantum chemistry ...


A guide to analysis and reconstruction of serial block face scanning electron microscopy data

15-Jan-2018 | E. COCKS, M. TAGGART, F.C. RIND, K. WHITE, Journal of Microscopy, 2018

Summary Serial block face scanning electron microscopy (SBF‐SEM) is a relatively new technique that allows the acquisition of serially sectioned, imaged and digitally aligned ultrastructural data. There is a wealth of information that can be obtained from the resulting image stacks but this ...


Technical implementations of light sheet microscopy

11-Jan-2018 | Zagato Elisa, Brans Toon, Stefaan C. De Smedt, Remaut Katrien, Neyts Kristiaan, Braeckmans Kevin, Microscopy Research and Technique, 2018

Abstract Fluorescence‐based microscopy is among the most successful methods in biological studies. It played a critical role in the visualization of subcellular structures and in the analysis of complex cellular processes, and it is nowadays commonly employed in genetic and drug screenings. ...


STED‐TEM Correlative Microscopy Leveraging Nanodiamonds as Intracellular Dual‐Contrast Markers

18-Dec-2017 | Neeraj Prabhakar, Markus Peurla, Sami Koho, Takahiro Deguchi, Tuomas Näreoja, Huan‐Cheng Chang, Jessica M. Rosenholm ..., Small, 2017

Abstract Development of fluorescent and electron dense markers is essential for the implementation of correlative light and electron microscopy, as dual‐contrast landmarks are required to match the details in the multimodal images. Here, a novel method for correlative microscopy that utilizes ...


Expansion microscopy of zebrafish for neuroscience and developmental biology studies [Neuroscience]

12-Dec-2017 | Limor Freifeld; Iris Odstrcil; Dominique Förster; Alyson Ramirez; James A. Gagnon; Owen Randlett; Emma K. Costa; Sho ..., Proceedings of the National Academy of Sciences current issue, 2017

Expansion microscopy (ExM) allows scalable imaging of preserved 3D biological specimens with nanoscale resolution on fast diffraction-limited microscopes. Here, we explore the utility of ExM in the larval and embryonic zebrafish, an important model organism for the study of neuroscience and ...


Bond-Selective Imaging of Cells by Mid-Infrared Photothermal Microscopy in High Wavenumber Region

27-Oct-2017 | Yeran Bai; Delong Zhang; Chen Li; Cheng Liu; Ji-Xin Cheng, The Journal of Physical Chemistry B, 2017

Using a visible beam to probe the thermal effect induced by infrared absorption, mid-infrared photothermal (MIP) microscopy allows bond-selective chemical imaging at submicron spatial resolution. Current MIP microscopes cannot reach the high wavenumber region due to the limited tunability of the ...

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 ...


From patients to partners

20-Oct-2017 | Peter DelNero; Alexandra McGregor, Science , 2017

When we started graduate school 5 years ago, we were determined to learn everything we could about cancer. We spent all our time in the lab developing an arsenal of experimental techniques. However, in our daily work with petri dishes and microscopes, we felt that something was missing. We learned


Metrology of Multiphoton Microscopes Using Second Harmonic Generation Nanoprobes

19-Sep-2017 | Pierre Mahou, Guy Malkinson, Élodie Chaudan, Thierry Gacoin, Emmanuel Beaurepaire, Willy Supatto, Small, 2017

Abstract In multiphoton microscopy, the ongoing trend toward the use of excitation wavelengths spanning the entire near‐infrared range calls for new standards in order to quantify and compare the performances of microscopes. This article describes a new method for characterizing the imaging ...
