Endowing superhydrophobic coatings (SHCs) with photothermal properties has become a promising approach to overcoming the icephobic performance failure of SHCs in low-temperature and high-humidity environments. However, reported rely on petroleum-based resources are nonrecyclable, which is not conducive resource conservation environmental protection. In addition, they also prone external damage that shortens their service life. Herein, fully biobased epoxy vitrimer self-healing...

Uniform carbon spheres with hollow core and porous shell structures were controllably fabricated through carbonizing fine core/shell particles of polystyrene/cross-linked poly(cyclotriphosphazene-co-4,4'-sulfonyldiphenol), obtained by a simple template approach.

Highly cross-linked, intrinsically fluorescent organic–inorganic hybrid polymer microspheres bearing primary amine groups on the surface have been successfully prepared through a one-pot polycondensation of hexachlorocyclotriphosphazene with benzidine. Just by single-step introduction plentiful π-conjugated benzidine units in structure, resulting easily obtain both luminescence and abundant active amino groups, no need for more modification. Thus further using as fluorescence-based...

Abstract Despite tremendous advancements in icephobic coating technology, efficacy frequently declines or completely disappears low temperatures, high humidity, and dynamic environments. Here, a hyperbranched vanillin‐based composite with efficient properties (HVIC) is prepared by combining phosphazene compounds oil‐stored SiO 2 through imine bonds‐ HVIC exhibits excellent hydrophobicity, water sliding angle of 9°. This coating's exceptional slippery performance imparts outstanding...

Abstract Fully crosslinked, stable poly[cyclotriphosphazene‐ co ‐(4,4′‐sulfonyldiphenol)] (PZS) microspheres have been prepared via the polycondensation between hexachlorocyclotriphosphazene and 4,4′‐sulfonyldiphenol by precipitation polymerization. The diameter of PZS ranged from 0.6 to 1.0 µm with specific surface area ranging 11.7 10.1 m 2 · g −1 . formation non‐porous was observed obey an oligomeric species absorbing mechanism. fully crosslinked chemical structure were determined IR,...

In this letter, considering the simultaneous wireless information and power transfer scheme, we study robust artificial noise (AN)-aided secure transmission design in multiple-input-single-output channels where channel uncertainties are modeled by worst-case model. Our objective is to maximize secrecy rate with respect both eavesdropper among multiple eavesdroppers, under transmit constraint energy harvesting constraint. The optimal solution problem can be found two-dimensional (2-D) search....

The lower total temperature and pressure in a dual-mode scramjet engine lead to slower rates of evaporation chemical reactions, while the inflow velocity is higher than that ramjet engine. Consequently, enhancing fuel residence time becomes more critical challenge. cavity crucial device for time. However, quantitative capacity mechanism have not yet been revealed, especially wide-range speed conditions. This work employs delayed detached eddy simulation method investigate mass transport...

A comprehensive theoretical model for the primary breakup of liquid jets in subsonic crossflow was developed. The theoretically analyzed jet deformation process, mass stripping and influence several critical forces consequently provided highly accurate predictions trajectory. Deformation cross section considered as a two-stage process based on physical characteristics, including spring-mass analogy induced deformation. modeled an exponential function time experimental findings droplets....

An instrumentation system using multiple electrostatic sensing heads developed installed 510-mm bore same mill 600-MW unit PF mass flow velocity distributions. array electrodes with different axial widths housed in head. electrode greater width three narrower...

The distance over which a normal shock motion passes is generally considered to be negatively correlated with the rising rate of backpressure; however, our experiments show that independent backpressure for oblique trains. Single-pulse was constructed decouple amplitude and remove its cumulative effects first time at Ma = 1.95. Unlike shock, when begins fall, train does not immediately retreat but rather moves upstream terminal position. mixing region may play an important role in this...

In the tandem turbine-based combined cycle engine's hyperburner, complex intrusive design is usually employed to achieve ignition and stable combustion under high-speed low-temperature extreme conditions. This paper proposes a concise, non-intrusive coupled swirler-cavity configuration supply fuel with good atomization at cavity-trapped vortex center, thereby ensuring formation of initial flame kernel. Under guidance vortex, kernel grows through dynamic “rotation-diffusion” mechanism....
