The development of new direct electron detection as well as low-noise, high-speed CMOS cameras has enabled an entirely new realm of analytical (scanning) transmission electron microscopy, including 4D STEM and in-situ videography. In this webinar, we will discuss the integration of a ClearView camera into the JEOL ARM200CF at the University of Illinois – Chicago for atomic-resolution, in-situ, and 4D STEM analysis over a range of acceleration voltages and imaging conditions.  Specifically, we will highlight some recent results, including the in-situ transformation of Mg(Mn,Cr)₂O₄, phase analysis in complex oxide thin films, and electrochemistry measurements using an in-situ liquid-cell at elevated temperatures. Imaging with the ClearView camera is combined with high-resolution EELS measurements using the GIF Continuum.

A short introduction to Raman spectroscopy, aimed at those interested in integrating Raman measurements to their experiments.  We will review what information can be revealed by Raman spectroscopy, fundamental limitations, and typical experimental setups in the context of developments in instrumentation over the last few decades.

Some common applications for Raman spectroscopy will be explored, including chemical identification.  A brief and practical overview will be given of some Raman measurement modalities, including resonance Raman, SERS, TERS, mapping, and widefield Raman imaging.  We will contrast Raman spectroscopy to its more popular vibrational cousin, infrared absorption.

Learning Objectives

• What information content a Raman spectrum contains.  What can be trivially learned from examination of a spectrum, and further what small changes in e.g. peak energies can imply. What’s so special about the so-called “fingerprint region”?
• The minimum experimental requirements for measuring Raman spectra, as well as some specialised variations used for more niche applications.
• In what situations Raman spectroscopy can likely be used, and alternatively, when measurement of Raman spectra is likely impossible due to the fundamental limitations of the technique.

Cambridge, United Kingdom / Delft, Netherlands, 22nd April 2024: Toshiba Europe Ltd. and Single Quantum B.V. have collaborated to test and validate long-distance deployments of Quantum Key Distribution (QKD) technology. Following extended validation testing of Toshiba’s QKD technology and Single Quantum’s superconducting nanowire single photon detectors (SNSPDs), both companies are pleased to announce a solution that substantially extends the transmission range for QKD deployment over fibre connections, up to and beyond 300km.

QKD uses the quantum properties of light to generate quantum secure keys that are immune to decryption by both high performance conventional and quantum computers. Toshiba’s QKD is deployed over fibre networks, either coexisting with conventional data transmissions on deployed ‘lit’ fibres, or on dedicated quantum fibres. Toshiba’s unique QKD technology can deliver quantum secure keys in a single fibre optic link at distances of up to 150km using standard integrated semiconductor devices. Achieving longer distance QKD fibre transmission is challenging due to the attenuation of the quantum signals along the fibre length, (the optical loss of the fibre link). To provide extended QKD transmission, operators typically concatenate fibre links together with trusted nodes along the fibre route which house QKD systems that relay the secret keys.

Semrock stocks the widest selection of Raman-spectroscopy edge filters available, with edge wavelengths from 224 to 1550nm. These filters are so steep and highly transmitting that they out perform even the leading holographic notch filters, yet are less than half the price. Now you can see the weakest signals closer to the laser line than before. With deep laser-line blocking, ultra-wide and low-ripple passbands, proven hard-coating reliability, and high laser damage threshld, they offer performance that lasts.
