Ultrathin MWCNT/Ti₃C₂T_x Hybrid Films for Electromagnetic Interference Shielding

Nanomaterials
The disordered assembly and low conductivity of carbon nanotubes are the main problems that limit the application of electromagnetic interference (EMI) shielding. In this work, an ordered lamellar assembly structure of multiwalled carbon nanotube/Ti3C2Tx

An ultra-thin high-efficiency plasmonic metalens with symmetric split ring transmitarray metasurfaces

Results in Physics, 2023
Metasurface lenses (or metalenses) have aroused great attentions and efforts in the community of metamaterials or metasurfaces due to its ultrathin device dimension and superior focusing performances. High-efficiency transmissive metalenses with an ultra-

Monte Carlo simulations of a diffusive shock with multiple scattering angular distributions

, 2011
We independently develop a simulation code following the previous dynamical Monte Carlo simulation of the diffusive shock acceleration under the isotropic scattering law during the scattering process, and the same results are obtained.

The anti‐CRISPR protein AcrIE8.1 inhibits the type I‐E CRISPR‐Cas system by directly binding to the Cascade subunit Cas11

FEBS Letters, EarlyView.
In this study, we present the structure of AcrIE8.1, a previously uncharacterized anti‐CRISPR protein that inhibits the type I‐E CRISPR‐Cas system. Through a combination of structural and biochemical analyses, we demonstrate that AcrIE8.1 directly binds to the Cas11 subunit of the Cascade complex to inhibit the CRISPR‐Cas system.

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

FEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Terahertz bistatic three-dimensional computational imaging of hidden objects through random media

Scientific Reports
Random media pose limitations on the imaging capability of photoelectric detection devices. Currently, imaging techniques employed through random media primarily operate within the laser wavelength range, leaving the imaging potential of terahertz waves ...

Excitation of Terahertz Spoof Surface Plasmons on a Roofed Metallic Grating by an Electron Beam

Micromachines
In this paper, both fundamental SSP modes on a roofed metallic grating and its effective excitation of the bounded SSP mode by an injected electron beam on the structure are numerically examined and investigated in the THz regime.

Analytical Formulas for Wave Propagation at Low Frequencies in Half-Spaces Due to a Horizontal Magnetic Dipole

IEEE Access, 2020
The Sommerfeld Integrals (SIs) are re-visited in the presence of half-spaces under the assumption of γ0 ≈ iλ being valid for low-frequency propagation in order to investigate the near-field due to a Horizontal Magnetic Dipole (HMD ...

Towards spatially resolved magnetic small-angle scattering studies by polarized and polarization-analyzed neutron dark-field contrast imaging

Scientific Reports, 2021
In the past decade neutron dark-field contrast imaging has developed from a qualitative tool depicting microstructural inhomogeneities in bulk samples on a macroscopic scale of tens to hundreds of micrometers to a quantitative spatial resolved small ...
