Metasurface-based terahertz wideband linear polarization converter

Results in Optics, 2023
We designed a linear polarization converter based on metasurface and simulated its functionality. It has a broad bandwidth and operates in the terahertz frequency range (0.4–1.2 THz).

Single Viruses on the Fluorescence Microscope: Imaging Molecular Mobility, Interactions and Structure Sheds New Light on Viral Replication

Viruses, 2018
Viruses are simple agents exhibiting complex reproductive mechanisms. Decades of research have provided crucial basic insights, antiviral medication and moderately successful gene therapy trials. The most infectious viral particle is, however, not always

Near infrared spectroscopic assessment of engineered cartilage for implantation in a pre-clinical model

Journal of Cartilage & Joint Preservation, 2022
Introduction: Articular cartilage lacks the capacity for self-repair due to its relative avascularity. Regenerative medicine approaches are now widely investigated, but optimal solutions have not been identified.

Low-temperature magnetic crossover in the topological kagome magnet TbMn6Sn6

Communications Physics, 2022
Kagome metals house a range of competing ground states leading to superconducting as well as topological features and so there has been significant recent interest in their underlying physics.

Differences in structural and functional networks between young adult and aged rat brains before and after stroke lesion simulations

Neurobiology of Disease, 2019
Neural network changes during aging may contribute to vulnerability and resilience to brain lesions in age-related neurological disorders, such as stroke. However, the relationship between age-related neural network features and stroke outcome is unknown.

Optical Imaging Spectroscopy [PDF]

Solar Physics, 2015
During the recent solar maximum the combination of imaging and spectroscopy in the visible part of the spectrum became a powerful tool for observational study of flares primarily because of the development of two-dimensional charge-coupled-device (CCD) arrays.
