Developing highly efficient and multifunctional membranes toward oil adsorption oil/water separation is of significance in oily wastewater treatment. Herein, a novel electrospun composite membrane with dual-scaled porous structure nanoraised on each fiber was fabricated through electrospinning using biodegradable polylactide (PLA) magnetic γ-Fe2O3 nanoparticles. The PLA/γ-Fe2O3 show high porosity (>90%), superhydrophobic superlipophilic performances CH2I2 contact angle 0°, good water...
The extensive use of computed tomography (CT) in diagnostic procedures is accompanied by a growing need for more accurate and patient-specific dosimetry techniques. Optically stimulated luminescent dosimeters (OSLDs) offer potential solution CT point-based surface measuring air kerma. purpose this work was to characterize the OSLD nanoDot dosimetry, quantifying necessary correction factors, evaluating uncertainty these factors.A characterization Landauer OSL (Landauer, Inc., Greenwood, IL)...
We report the investigation of a nano-scale antireflection structure in black scales Troides aeacus butterfly wing, which can be viewed as natural solar collector. The intelligence light capturing hides itself intricate architectures aside from melanin effect. Reflection and transmission spectra were obtained experimentally well with 3D FDTD (three dimensional finite difference time domain) method. Poynting vector maps show energy distribution reflection micro geometric portrayed well....
Preference optimization for diffusion models aims to align them with human preferences images. Previous methods typically leverage Vision-Language Models (VLMs) as pixel-level reward approximate preferences. However, when used step-level preference optimization, these face challenges in handling noisy images of different timesteps and require complex transformations into pixel space. In this work, we demonstrate that are inherently well-suited modeling the latent space, they can naturally...
We propose a method of computational temporal ghost imaging over single optical fiber using simple intensity detection instead coherent detection. The transfer function system is derived, which the total dispersion and power density spectrum light source. In simulations, we find that bandwidth will decrease rapidly along with increase length or source bandwidth, resulting in significantly distorted image. To improve image quality, first calculate by approximating based on as its spectrum....
The dual-comb technique is a powerful tool in industrial inspection and scientific research capable of realizing ultrahigh-resolution fast broadband spectral measurements. We propose an absolute angular-position measurement method based on spectroscopy. With simple layout, the angular position can be naturally determined through traceable wide-amplitude spectra autocollimation diffracted beams target grating. experimentally demonstrate that precision 0.12 arcsec dynamic range approximately...
Abstract Essentially all biological processes are highly dependent on the nanoscale architecture of cellular components where these take place. Statistical measures, such as autocorrelation function (ACF) three-dimensional (3D) mass–density distribution, widely used to characterize nanostructure. However, conventional methods reconstruction deterministic 3D from which statistical measures can be calculated, have been inadequate for thick structures, whole cells, due conflict between need...
A twice oblique ion beam etching method is proposed to fabricate triangular blazed gratings that have controllable both blaze angle and anti-blaze angle. The controlled by first obliquely the photoresist mask obtain an asymmetrical trapezoidal grating, one sidewall of which then evolves into facet in second etch step. grating a grating. We show key process steps fabricating with 20.9° 89.0°. verified not only increase near 90°, but also good tolerance against over-etching.
A systematic study of secondary electron collaborative the radio-frequency (RF) inductively coupled plasma (ICP) surface modification PET film and its physical chemical changes were analyzed. It was found that with a RF plasma, contact angle reduced to 17 ° in 5 seconds RMS roughness is enhanced by 7 times higher than only treatment film. The atomic force microscopy (AFM) X-ray photo spectroscopy (XPS) employed investigate characteristics treatments. amount oxygen-containing polar functional...
We analyzed fabrication errors of nonperiodic-multilayer-dielectric gratings that were designed to have a high reflective diffraction efficiency for one wavelength and transmittance another at the same time. Significant deviations found between measured calculated values although groove profile parameters very closed design values. The source error was attributed coating film stack. To explain deviation well, we estimated actual stack by reverse calculations using scanning electron...
Polarization grating (PG) divides the incident wave into left- and right-handed circularly polarized waves, intensities of two waves depending on state polarization wave. Large deflection angle commercial PG is usually made by cascade due to limit period. While using tensor holography theory, arbitrary angles PGs have been designed, where polarization-sensitive material phenanthraquinone-doped polymethyl methacrylate (PQ/PMMA) utilized as recording medium in our experiments. We with 40°.
