“…Furthermore, the saturation of the color, as determined from the ratio of the peak reflectivity (at 682 nm, red line) to the reflectivity at short wavelengths in These saturation values are significantly higher than those previously reported in the literature for systems with angle-independent structural red colors. 15,16,37 Angle-independent Colors from Inverse Photonic Glasses.…”

“…Many recent papers discuss the use of melanin or similar materials in concert with colloidal assembly to create red colors. [15][16][17][18][19] The melanin absorbs blue light, [15][16] which can eliminate the secondary peak in the blue. Here we seek to avoid the use of melanin and other dyes, because wavelength-specific absorption is the basis of traditional color.…”

A major fabrication challenge is producing disordered photonic materials with an angle-independent structural red color. Theoretical work has shown that such a color can be produced by fabricating inverse photonic glasses with monodisperse, nontouching voids in a silica matrix. Here, we demonstrate a route toward such materials and show that they have an angle-independent red color. We first synthesize monodisperse hollow silica particles with precisely controlled shell thickness and then make glassy colloidal structures by mixing two types of hollow particles with the same core size and different shell thicknesses. We then infiltrate the interstices with index-matched polymers, producing disordered porous materials with uniform, nontouching air voids. This procedure allows us to control the light-scattering form factor and structure factor of these porous materials independently, which is not possible to do in photonic glasses consisting of packed solid particles. The structure factor can be controlled by the shell thickness, which sets the distance between pores, whereas the pore size determines the peak wave vector of the form factor, which can be set below the visible range to keep the main structural color pure. By using a binary mixture of 246 and 268 nm hollow silica particles with 180 nm cores in an index-matched polymer matrix, we achieve angle-independent red color that can be tuned by controlling the shell thickness. Importantly, the width of the reflection peak can be kept constant, even for larger interparticle distances.

“…[26] In fact, interestingly, it has been found that the B atoms prefer to substitute for some of the Ti atoms and drive the Ti into the interstitial. [31] The nature of the Ce 4f state different Ce-T M compounds is often a controversial subject. [32] The anomalies in the lattice constants as well as the magnetic moment and Curie temperature have been interpreted as evidence of the mixed-valence (between Ce 3+ and Ce 4+ ) behavior of the cerium ion.…”

To guide improved properties coincident with reduction of critical materials in permanent magnets, we investigate via density functional theory (DFT) the intrinsic magnetic properties of a promising system, R(Fe1−xCox)11TiZ with R=Y, Ce and interstitial doping (Z=H, C, N). The magnetization M , Curie temperature TC, and magnetocrystalline anisotropy energy K calculated in local density approximation to DFT agree well with measurements. Site-resolved contributions to K reveal that all three Fe sublattices promote uniaxial anisotropy in YFe11Ti, while competing anisotropy contributions exist in YCo11Ti. As observed in experiments on R(Fe1−xCox)11Ti, we find a complex nonmonotonic dependence of K on Co content, and show that anisotropy variations are a collective effect of MAE contributions from all sites and cannot be solely explained by preferential site occupancy. With interstitial doping, calculated TC enhancements are in the sequence of N>C>H, with volume and chemical effects contributing to the enhancement. The uniaxial anisotropy of R(Fe1−xCox)11TiZ generally decreases with C and N; although, for R=Ce, C doping is found to greatly enhance it for a small range of 0.7

“…Zhang et al. 47–48 studied the propagation characteristics of ultrasonic in circular, corrugated, threaded, and horizontal grain tubes. The best cavitation length of ultrasonic cavitation was 4.0 m, and because of the different turbulence intensity, the ultrasonic cavitation effect in the horizontal grain tube and threaded tube was superior to the circular tube.…”

The presence of scale substances seriously affects the normal operation of industrial equipment. Ultrasonic scaling removal technology has been getting significant attention because of cleanliness, safety and no secondary pollution. As a new heat transfer enhancement technology, ultrasonic has also achieved good results. This article reviews the research progress and innovations made in recent years on the ultrasonic scaling removal technology and heat transfer enhancement technology. A special focus is concentrated on the influence of the key factors on the comprehensive performance. These factors include ultrasonic parameters, fluid parameters, geometry parameters. At present, ultrasonic heat transfer enhancement technology mainly stays in the laboratory research stage, and there is no industrial‐scale application.
