We have studied the adhesion state (also denoted by docking state) of lipid vesicles as induced divalent ions Ca2+ or Mg2+ at well-controlled ion concentration, composition, and charge density. The bilayer structure interbilayer distance in were analyzed small-angle x-ray scattering. A strong was observed for DOPC:DOPS vesicles, indicating like-charge attraction resulting from correlations. separations ∼1.6 nm agree quantitatively with predictions electrostatics coupling regime. Although...
Transmembrane β-peptides are promising candidates for the design of well-controlled membrane anchors in lipid membranes. Here, we present synthesis transmembrane with and without tryptophan anchors, as well a novel iodine-labeled d-β(3) -amino acid. By using one or more heavy-atom labeled amino acids markers, orientation helical peptide was inferred based on electron-density profile determined by X-ray reflectivity. The were synthesized through manual Fmoc-based solid-phase (SPPS)...
X-ray free-electron lasers (XFELs) with megahertz repetition rates enable photon correlation spectroscopy (XPCS) studies of fast dynamics on microsecond and sub-microsecond time scales. Beam-induced sample heating is one the central concerns in these studies, as interval often insufficient for heat dissipation. Despite great efforts devoted to this issue, few have evaluated thermal effects beam profiles. This work compares effective three common profiles using numerical methods. Results show...
Due to the inefficiency of effective wave modulation components and dynamical metamaterial in terahertz (THz) range, an alternative approach frequency sweeping for beam scanning based on a metasurface structure is proposed here. Aiming at broadband high-efficiency circular-polarized frequency-scanning, we start with combining Pancharatnam-Berry scheme generalized Snell's law initiate fundamental schematic design. The hybrid structural unit composed I-shaped dipole two rectangular dipoles...
High repetition-rate X-ray free-electron lasers (XFELs) enable the study of fast dynamics on microsecond time scales. Split-delay lines (SDLs) further bring scale down to femtoseconds by splitting and delaying XFEL pulses. Crystals multilayers are two common types optical elements in SDLs, offering either long delay ranges or high temporal accuracy. In this work, we introduce design a hybrid SDL for coherent diffraction endstation Shanghai Repetition Rate Extreme Light Facility (SHINE). It...
Metasurfaces have shown extraordinary ability to manipulate the wavefront of electromagnetic wave and varieties functional devices been proposed. However, due dispersion phase accumulated in light path, metasurfaces suffer from large chromatic aberration thus limit their usages many domains. Here, a metasurface-based circularly polarized broadband reflective device is proposed, focusing on directional reflectors focusers constructed by metasurface elements, eliminate aberration. Utilizing...
Spoof surface plasmon polaritons (SSPP) is an electromagnetic wave that can be tightly confined near the interface between metal and medium; it solve crosstalk problem caused by strong mutual coupling in highly integrated circuits. Using this feature expected to break through bottleneck of circuit development. In paper, we construct a spoof transmission line embedding hybrid ELC resonators within grooves periodic unit achieve tunable filtering effect. For dynamic regulation, combine vanadium...
Abstract Sequential X-ray photon correlation spectroscopy (XPCS) reveals sample dynamics by analyzing a series of coherent scattering images, which is often time-consuming. For applications like real-time XPCS analysis, high efficiency desired. Pixel binning straightforward strategy to reduce the processing time, but over-binning may result in an insufficient signal-to-noise ratio. In this work, feature detection applied obtain optimal factor for image processing. Results show that under...
