One-dimensional ZnSe/ZnS/BK7 ternary planar photonic crystals as wide angle infrared reflectors
Results in Physics, 2021 In this work, we propose novel structures of one-dimensional ternary planar photonic crystals (1D-TPPC) consisting of periodic unit cells of dispersive materials.

Comment on “Photonic Band Gaps: Noncommuting Limits and the `Acoustic Band' ” [PDF]
Physical Review Letters, 2001 This Comment concerns the effective dielectric constant for 2D photonic crystal. We show that even in the limit of very high dielectric constant of photonic crystal's "atoms", static and quasistatic approaches give the same results, unlike it was claimed by Nicorovichi et al, PRL, 75, 1507 (1995).

Superprism phenomena in planar photonic crystals
, 2010 We utilize the anomalous dispersion of planar photonic crystals near the dielectric band edge to control the wavelength-dependent propagation of light. We typically observe an angular swing of up to 10degrees as the input wavelength is changed from 1290 ...

Majlesi Journal of Electrical Engineering, 2023 This study presents a photonic bandgap formation in a non-uniform 2D photonic crystal structure with low index rods relative to the air background. In order to find an absolute photonic band gap formation, photonic lattices of two non-uniform square and ...

Molecular Oncology, EarlyView.Ixazomib inhibits proteasome‐mediated degradation of topoisomerase I induced by irinotecan, thereby restoring drug sensitivity and promoting tumor cell death in colorectal cancer. Irinotecan, a topoisomerase I (topoI) inhibitor, is widely used for colorectal cancer, but resistance remains a major clinical challenge.

Photonic Band Gaps and Resonance Modes in 2D Twisted Moiré Photonic Crystal
Photonics, 2021 The study of twisted bilayer 2D materials has revealed many interesting physics properties. A twisted moiré photonic crystal is an optical analog of twisted bilayer 2D materials. The optical properties in twisted photonic crystals have not yet been fully

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies
FEBS Open Bio, EarlyView.We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...
