SFE-CO2 is a novel, promising, environmentally benign and inexpensive extracting method developed over the past few years to overcome environmental problems encountered due use of conventional solvents. One component (the extractant) separated from another matrix) using SCF-CO2 as This widely used for heavy metals contaminant, bioactive compounds like antioxidants, plant medicine natural products or remediating metal contaminated soil by good binding activity ions. The major advantages...
Steam generation through efficient utilization of solar energy is a promising technology in addressing the challenge global freshwater shortage and water pollution. One biggest hurdles for traditional photothermal membranes to function continuously high temperature, salt, corrosive environment has been attributed their rapid decline mechanical properties. In this work, highly solar-driven interfacial evaporation system developed via polydopamine/carbon/silicon (PCS) composite membrane...
Abstract Melt electrospinning is a much more simple and safe method to produce ultra fine fibers than solution electrospinning. The diameters of melt are thicker. To find the factors that affect diameter in electrospinning, orthogonal design was used examine temperature, spinning voltage, distance, flow rate (MFR) polymer. Results showed MFR at present three levels has most important impact both on average standard deviations fiber diameters. scanning electron microscopy pictures show all...
A new design method for ultrabroadband radar cross section (RCS) reduction by exploiting characteristic complementary polarization conversion metasurfaces (PCMs) is proposed and validated. The lifts the conventional bandwidth limitation enforced performance of a single PCM expands RCS bandwidth. systematic strategy developed an effective reflection coefficient amplitude composite surface ( <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML"...
The burrow microhabitats created by burrowing mammals, as a hotspot for biodiversity distribution in ecosystems, provide multiple critical resources many other sympatric species. However, the cascading effects of on animal community assemblages and interspecific interactions are largely unknown. During 2020-2023, we monitored 184 Chinese pangolin (Manis pentadactyla) burrows using camera traps to reveal utilization patterns commensal We totally recorded up 57 species, with 19 mammal 32 bird...
The terahertz (THz) band has attracted significant interest for future wireless networks. In this paper, a THz integrated sensing communications and powering (THz-ISCAP) system, where is leveraged to enhance powering, studied. For given total amount of time, we aim determine an optimal time allocation improve the efficiency along with power splitting ratio balance these two functionalities. This achieved by maximizing between either achievable rate or harvested energy while ensuring minimum...
This paper presents 70-77 GHz wideband channel characteristics of delay, spatial, and polarimetric domains for small office entrance hall scenarios. Based on measured multidimensional power spectra directions (i.e., azimuth elevation) departure arrival, multipath clusters were detected using the K-means, threshold-based, Gaussian-mixture-model clustering algorithms. The spatial positions clusters, including first- last-hop scatterers, are determined a measurement-based ray tracer method. Our...
In this article, an automatic and forward method is realized to establish attributed scattering center models directly from the computer-aided design (CAD) model of complex target. The main steps include preprocessing CAD model, separation sources, selection strong determination parameters. With proposed method, mechanisms, parameters centers can be identified derived, such that complicated manual intervention completely avoided. Moreover, establishes distributed formed by curved surfaces...
In this article, a 2-D bistatic attributed scattering center (BASC) model is developed to represent the return from perfect electric conducting (PEC) target, based on derived analytic solutions of seven canonical primitives. Because its unified and concise form, BASC useful for extracting geometrical features targets synthetic aperture radar (SAR) echoes. However, estimating parameters an ill-posed inverse problem. To reduce ill-posedness, we present sparse method that incorporates...
Laser induced graphitization of polyacrylonitrile-based carbon fibers (CFs) was carried out in a self-designed furnace with CO2 laser source. The microstructures combined mechanical properties the irradiated CFs were measured by Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), wide-angle diffraction (WAXD), scanning electron microscopy (SEM), high resolution transmission (HRTEM) and single filament tensile test, respectively. results exhibited that hierarchical structures showed...
Abstract The excavation of Chinese pangolin ( Manis pentadactyla ) is expected to alter habitat heterogeneity and thus affect the functioning structure forest ecosystems. In this study, bioturbation on soils in three regions (Heping, Tianjingshan, Wuqinzhang) across Guangdong province was quantified. Overall, a mean 2.66 m 3 ·ha −1 83.1 2 burrows bare mounds, respectively, excavated by pangolin; disturbed had significantly lower water content P, C, available N concentrations, but higher bulk...
