The behavior of undergoing cosmetic surgery is a coping strategy for body-image threats and challenges. Self-objectification is associated with alienation and body image inflexibility, and all of these are associated with stronger cosmetic surgery considerations. This study evaluated the relationship between self-objectification and cosmetic surgery consideration, and whether this relationship was mediated by alienation and body image inflexibility. The participants were 650 Chinese female college students. Serial mediation analysis indicated that the relationship between self-objectification and cosmetic surgery consideration was significantly mediated by alienation followed by body image inflexibility. The total mediating effect value was 0.424, accounting for 57.5% of the total effects. These results suggest that reducing alienation and improving the flexibility of body image can reduce the influence of self-objectification on young women's willingness to undergo cosmetic surgery. These findings provide a basis for intervening or preventing the self-objectified young women's willingness for cosmetic surgery. [ABSTRACT FROM AUTHOR]

Little research has been conducted on one dimensional non-perovskite δ-CsPbBr3, due to its metastability under atmospheric conditions. However, it was discovered that the white metastable δ-CsPbBr3 can be stabilized as δ-CsPbBr2.7I0.3 by substituting 10% Br with I. [ABSTRACT FROM AUTHOR]

In this study, a new lattice Boltzmann scheme is developed for the two-phase CuO–H2O nanomagnetic fluid (ferrofluid) under a non-uniform variable magnetic field. It introduces the second-order external force term including both MHD (magnetohydrodynamic) and FHD (ferrohydrodynamic) into the lattice Boltzmann equation. The square cavity and a heat source inside the circular cavity with natural convections of nanofluid are investigated, respectively. The effects of Rayleigh number (Ra), the volume fraction of nanoparticles (φ), Hartmann number (Ha) generated by MHD, and magnetic number (MnF) generated by FHD on the nanofluid flow and heat transfer properties, as well as the total entropy generation (Stot) have been examined. The two-phase lattice Boltzmann model has demonstrated that it is more accurate in predicting the heat transfer of nanofluid than the single-phase model. Consequently, the results calculated by the single-phase and the two-phase methods show the opposite trends. It indicates that nanoparticles could enhance heat transfer with maximum values of 1.78% or deteriorate heat transfer with maximum values of 14.84%. The results of the circular cavity show that Ha could diminish the flow intensity, whereas MnF could enhance it. The average Nusselt number (Nuave) on the heat source decreases with the augments of Ha and MnF but increases with Ra. An optimal volume fraction φ = 1% for heat transfer is obtained except for Ra = 104. Stot achieves the maximum value at Ha = 40 when Ra = 105. It increases with a rise of Ra but reduces with an increment of φ. [ABSTRACT FROM AUTHOR]

In this study, the co-combustion of coal and biomass, and the tri-combustion of coal, biomass, and oil sludge in a 130 t h−1 circulating fluidized bed (CFB) boiler are investigated via the computational particle fluid dynamics (CPFD) approach. Furthermore, the effect of biomass feeding position is also comprehensively evaluated. The results show that for the co-combustion of coal and biomass, the O2 mole fraction at the furnace outlet rises from 0.0541 to 0.0640 as the biomass blending ratio enhances from 40% to 100%, while the CO2 mole fraction reduces from 0.1357 to 0.1267. The mole fraction of NOx and SO2 at the furnace outlet decreases from 4.5867 × 10−5 to 3.9096 × 10−5 and 2.8253 × 10−4 to 4.6635 × 10−5, respectively. For the tri-combustion of three fuels, the average NOx mole fraction initially grows quickly and then declines gradually, ranging from 4.1173 × 10−5 to 4.2556 × 10−5. The mole fraction of SO2 at the furnace outlet increases from 3.5176 × 10−4 to 4.7043 × 10−4 when the ratio of oil sludge rises from 10% to 20%. The uniformity of temperature and gas components distribution is "new inlet > secondary air inlet > feed inlet". As for the three inlet positions, the mole fractions of NOx at the furnace outlet are between 3.9096 × 10−5 and 5.1537 × 10−5, while those for SO2 are between 2.5978 × 10−4 and 2.5278 × 10−4.

All-inorganic halide perovskite semiconductors have received extensive attention due to their excellent photoelectronic conversion efficiency. Prior studies have reported on compounds CsPbBr 3 and CsPbCl 3 . However, the transition phases between them have not been systematically studied. Here, a series of large-size single crystals of CsPbBr x Cl 3- x ( x = 0-3) were successfully grown by the Bridgman method, which proves that the Br and Cl atoms can be miscible in any proportion in the solid solution system, and the change of lattice parameters conforms to Vegard's law. Also, the bandgap and light emission were studied. It is found that the band gap (2.90-2.29 eV) and photoluminescence characteristics (from blue light to green light) can be effectively tuned by adjusting the content of the Br atom. These results provide valuable guidance for the development and optimization of photoelectronic semiconductors that can meet different practical demands.
