Small‐angle scattering studies on diverse peptide‐based nanotube and helical ribbon structures reveal distinct form and structure factors

open access: yesJournal of Applied Crystallography, Volume 58, Issue 4, Page 1311-1321, August 2025.
Peptide nanotubes have diverse structures, which can be elucidated by small‐angle scattering. Here, we discuss in detail appropriate models for form‐ and structure‐factor effects exemplified by analysis of data for several classes of peptide nanotubes.Peptide‐based nanotubes are bio‐based self‐assembled nanostructures with intriguing structural and ...

Angle‐ and Polarization‐Tolerant Metasurface Designs Based on the Aperiodic Tiling

open access: yesAdvanced Optical Materials, Volume 13, Issue 20, July 11, 2025.
A novel aperiodic metasurface design is introduced to mitigate the inherent angle and polarization sensitivity of conventional metasurfaces. By employing a recently discovered aperiodic tiling approach, identical elliptical scatterers are arranged with systematic variations in their spacing and orientation, effectively minimizing spectral reflectance ...

Об оценках распределения длины отрезка апериодичности в графе k-кратной итерации равновероятного случайного отображения

open access: yes, 2018
Работа посвящена исследованию случайной величины Tfk (xo), равной длине отрезка апериодичности произвольной вершины x0 € S = {1, . . . ,n}, n € N, в графе k-кратной итерации равновероятного случайного отображения f : S ^ S. Отрезком апериодичности, начинающимся в вершине xo € S, называется отрезок выходящей из х0 траектории от х0 до её первого ...
