Anomalous X-ray diffraction studies of ion transport in K+ channels

open access: yesNature Communications, 2018
The number of K+ occupied binding sites in the selectivity filter of potassium ion channels is still under debate. Here, the authors collect diffraction data on the K+ selective NaK channel NaK2K at a wavelength of 3.35 Å, close to the K absorption edge,

Static and dynamic light scattering by red blood cells: A numerical study. [PDF]

open access: yesPLoS ONE, 2017
Light scattering is a well-established experimental technique, which gains more and more popularity in the biological field because it offers the means for non-invasive imaging and detection.

Incipient ferroelectric to a possible ferroelectric transition in Te4+ doped calcium copper titanate (CaCu3Ti4O12) ceramics at low temperature as evidenced by Raman and dielectric spectroscopy

open access: yesAIP Advances, 2017
Partial replacement of Ti4+ by Te4+ ions in calcium copper titanate lattice improved its dielectric behaviour mostly due to cubic-to-tetragonal structural transformation and associated distortion in TiO6 octahedra. The relative permittivity values (23–30

Refinement of pore size at sub-angstrom precision in robust metal–organic frameworks for separation of xylenes

open access: yesNature Communications, 2020
Separation of xylene isomers is essential for the production of a wide range of materials, but current separation methods are energy intensive. Here the authors report separation of the three xylene isomers at room temperature, via refinement of the pore

Geometric Symmetry of Dielectric Antenna Influencing Light Absorption in Quantum-Sized Metal Nanocrystals: A Comparative Study

open access: yesFrontiers in Chemistry, 2018
Silica nanoparticles, optically transparent in the visible spectral region, represent a class of dielectric antenna to tune the propagation and local field distribution of the visible light through surface scattering while the energy loss is minimized ...

Simplifying the calculation of light scattering properties for black carbon fractal aggregates [PDF]

open access: yesAtmospheric Chemistry and Physics, 2014
Black carbon fractal aggregates have complicated shapes that make the calculation of their optical properties particularly computationally expensive. Here, a method is presented to estimate fractal aggregate light scattering properties

Detection of Airborne Nanoparticles through Enhanced Light Scattering Images

open access: yesSensors, 2022
A new method is proposed in this paper to detect airborne nanoparticles, detecting the light scattering caused by both the particle and the surrounding molecules, which can surpass the limitations of conventional laser optical methods while maintaining ...

Detection of nanoparticles suspended in a light scattering medium

open access: yesScientific Reports, 2021
Intentionally intensifying the light scattering of medium molecules can allow the detection of suspended nanoparticles under conditions not suitable for conventional optical microscopies or laser particle counters. Here, we demonstrate how the collective
