Clarification on Generalized Lau condition for X-ray interferometers based on dual phase gratings [PDF]

, 2019
To implement dual phase grating x-ray interferometry with x-ray tubes, one needs to incorporate an absorbing source grating. In order to attain good fringe visibility, the period of a source grating should be subject to a stringent condition. In literature some authors claim that the Lau-condition in Talbot-Lau interferometry can be literally ...

Introduction to Interferometry [PDF]

, 1997
This tutorial gives a general introduction to optical and infrared interferometry, specifically addressing two questions: `Can I use VLTI to observe my favourite object?' and `What will it tell me?' The observables measured by an interferometer are fringe visibility and closure phase, which can then be fitted by a model or used to reconstruct an image.

Bandwidth in bolometric interferometry [PDF]

Astronomy and Astrophysics, 2010
Bolometric Interferometry is a technology currently under development that will be first dedicated to the detection of B-mode polarization fluctuations in the Cosmic Microwave Background. A bolometric interferometer will have to take advantage of the wide spectral detection band of its bolometers in order to be competitive with imaging experiments.

Film‐Based Multi‐Photon Lithography for Efficient Printing of Electromagnetic Surface Structures

Advanced Materials Technologies, EarlyView.
This work introduces film‐based multi‐photon lithography as an efficient method for fabricating electromagnetic surface structures with 2D and 2.5D geometries, particularly THz and mid‐IR metasurfaces. These structures can be fabricated on various substrates, such as glass or silicon‐on‐insulator, over areas ranging from mm2 to cm2, achieving feature ...

Femtosecond Pulse Shaping with Semiconductor Huygens' Metasurfaces

Advanced Optical Materials, EarlyView.
Spatially variant silicon Huygens' metasurfaces enable femtosecond pulse shaping by tailoring the spectral phase and amplitude of incident pulses. Two key functionalities are demonstrated: temporal stretching and pulse splitting of an input Gaussian pulse.

KEAP1‐NRF2 protein–protein interaction inhibitors: Design, pharmacological properties and therapeutic potential

Medicinal Research Reviews, Volume 43, Issue 1, Page 237-287, January 2023., 2023
Abstract The transcription factor nuclear factor erythroid 2‐related factor 2 (NRF2) is considered the master regulator of the phase II antioxidant response. It controls a plethora of cytoprotective genes related to oxidative stress, inflammation, and protein homeostasis, among other processes.
