Electromagnetic lensing using the Aharonov–Bohm effect
Autor: Makoto Tokoro Schreiber, Cathal Cassidy, Menour Saidani, Matthias Wolf
Publikováno v: New Journal of Physics, Vol 26, Iss 4, p 043012 (2024)
We demonstrate theoretically and experimentally an electromagnetic lensing concept using the magnetic vector potential—in a region free of classical electromagnetic fields—via the Aharonov–Bohm (AB) effect. This toroid-shaped lens with poloidal

Water without windows: Evaluating the performance of open cell transmission electron microscopy under saturated water vapor conditions, and assessing its potential for microscopy of hydrated biological specimens.
Autor: Cathal Cassidy, Masao Yamashita, Martin Cheung, Chola Kalale, Hidehito Adaniya, Ryusuke Kuwahara, Tsumoru Shintake
Publikováno v: PLoS ONE, Vol 12, Iss 11, p e0186899 (2017)
We have performed open cell transmission electron microscopy experiments through pure water vapor in the saturation pressure regime (>0.6 kPa), in a modern microscope capable of sub-Å resolution. We have systematically studied achievable pressure le

Low-energy scanning transmission electron microscopy applied to ice-embedded biological macromolecules
Autor: Hidehito Adaniya, Martin Cheung, Masao Yamashita, Seita Taba, Cathal Cassidy, Tsumoru Shintake
Publikováno v: Microscopy.
In this report, we applied annular bright-field and annular dark-field low-energy (30 keV) scanning transmission electron microscopy imaging to a vitreous ice-embedded biological macromolecule, T4 phage, to investigate the applicability of these meth

Interpretation of mean free path values derived from off-axis electron holography amplitude measurements
Autor: Cathal Cassidy, Makoto Tokoro Schreiber, Marco Beleggia, Jun Yamasaki, Hidehito Adaniya, Tsumoru Shintake
Publikováno v: Cassidy, C, Schreiber, M T, Beleggia, M, Yamasaki, J, Adaniya, H & Shintake, T 2022, ' Interpretation of mean free path values derived from off-axis electron holography amplitude measurements ', Micron, vol. 162, 103346 . https://doi.org/10.1016/j.micron.2022.103346
In this work, we have explored the factors which govern mean free path values obtained from off-axis electron holography measurements. Firstly, we explore the topic from a theoretical perspective, and show that the mean amplitude reconstructed from o

New Zealand community mental healthcare provider experience in schizophrenia management with 3-monthly paliperidone palmitate
Autor: Wayne Miles, Cathal Cassidy
Publikováno v: Australasian Psychiatry
Objectives: To understand the impact of 3-monthly treatment with paliperidone palmitate on patient management, including non-adherence and relapse, from a psychiatrist and nurse perspective for 73 patients enrolled in a patient familiarisation progra

Improved sample dispersion in cryo-EM using 'perpetually-hydrated' graphene oxide flakes
Autor: Masao Yamashita, Cathal Cassidy, Tsumoru Shintake, Seita Taba, Kun-Lung Li, Martin Cheung, Hidehito Adaniya
Publikováno v: Journal of Structural Biology. 204(1):75-79
For many macromolecular complexes, the inability to uniformly disperse solubilized specimen particles within vitreous ice films precludes their analysis by cryo-electron microscopy (cryo-EM). Here, we introduce a sample preparation process using "per

Development of a SEM-based low-energy in-line electron holography microscope for individual particle imaging
Autor: Masao Yamashita, Martin Cheung, Cathal Cassidy, Tsumoru Shintake, Hidehito Adaniya
Publikováno v: Ultramicroscopy. 188:31-40
A new SEM-based in-line electron holography microscope has been under development. The microscope utilizes conventional SEM and BF-STEM functionality to allow for rapid searching of the specimen of interest, seamless interchange between SEM, BF-STEM

Bragg holography of nano-crystals
Autor: Tatiana Latychevskaia, Cathal Cassidy, Tsumoru Shintake
Publikováno v: Ultramicroscopy. 230:113376
Crystal diffraction is a well-established technique for high-resolution structural analysis of material science and biological samples. However, the recovered structure is a result of averaging over all the unit cells in the crystal, which smears out
