Abstract Sulfides are well investigated as thermoelectric materials but their performance is typically limited by low electrical conductivity. High in Cu 3 SbS 4 reported creating high valence vacancies, which efficiently provides multiple carriers. It revealed from the perspective of a chemical bond calculations that Al can serve vacancy stabilizer its entry into lattice forms intensified bonds with neighboring atoms and lowers formation energy. As result, average power factor 9 wt% CuAlS 2...
Extraordinarily high quantum efficiency and abnormal negative thermal quenching were simultaneously achieved in oxide phosphors Ca 7 Mg 2 Ga 6− y Al O 18 :Mn 4+ by structurally confining Mn -emitters at isolated octahedral sites.
Because thermal infrared (TIR) images are not affected by light and foggy environments, which widely used in various night traffic scenarios. Especially, also play an important role autonomous vehicles. However, low contrast lack of chromaticity have always been their problems. Image colorization is a vital technique to improve the quality TIR images, beneficial human interpretation downstream tasks. Despite image methods rapidly improved, detail blurriness color distortion colorized remain...
Archetype stuffed tridymites AM2O4 typically exhibit a polar P622-structure, characterized by MO4-tetrahedra arranged in UDUDUD ring topology, where U (up) and D (down) denote the orientation of with respect to plane grids. However, most adopt centrosymmetric structures due size mismatch between A-cation cavity [M2O4]n− anionic framework, which alters topology results centrosymmetry. Therefore, innovative strategies are pressingly needed design alternative topologies facilitate fine...
Mn4+-activated phosphors have shown wide prospective applications in phosphor-converted white light-emitting diodes (pc-WLEDs) and pc-LEDs used illumination indoor plant cultivation, respectively. Recently, double perovskites A2B'B''O6 with a tunable crystal structure versatile octahedral sites been extensively studied as good host matrixes for Mn4+-emitters to realize far-red emissions.

Abstract Complex thermoelectric materials composed of multiple phases with order/disorder mixing feature have drawn intense attention due to their high performance. However, some physical mechanisms relevant properties including the relationship between carrier mobility and disorder extent in these are still elusive. Here, a phase‐dependent edge (Cu 2 Sn 1‐ y S 3 ) 0.85 (CuGaS 0.15 solid solutions is demonstrated. By control over by increasing ratio tetragonal phase less disorder, weakened...
The site-selective Al 3+ -to-Ga substitution in doubly ordered spinel Mg 4 (Ga/Al)SbO 8 :Mn 2+/4+ can manipulate the Mn distributions, thereby resulting a tunable emission color and controllable optical thermometry sensitivity.
AB2O4-type spinel oxides were extensively investigated as prospective magnetic, photocatalytic, cathode, and host materials. Herein, a new Mg4InSbO8 was rationally designed structurally characterized by high-resolution X-ray powder diffraction (XRPD) in combination with neutron diffraction. crystallizes the Imma-superstructure lattice dimensions of = √2/2·aC, b 3√2/2·aC, c aC, where aC is parameter cubic (Fd3̅m) archetype spinel. The formation this hitherto unreported Imma-spinel...
Abstract Image hiding is a task that hides secret images into cover images. The purposes of image are to ensure the invisible human and can be recovered. current state‐of‐the‐art steganography methods run risk information leakage. A safe network (SIHNet) presented reduce leakage information. Based on some phenomena which use invertible neural network, reversible processing (SIP) module proposed make suitable for stego leak less Besides, lost (LIH) used hide images, thus method recover better...
Abstract Image hiding is a task that embeds secret images in digital without being detected. The performance of image has been greatly improved by using the invertible neural network. However, current methods are less robust face Joint Photographic Experts Group (JPEG) compression. cannot be extracted from stego after JPEG compression image. Some show good robustness for some certain quality factors but poor other common factors. An image‐hiding network (RIHINNet) to all proposed. First all,...
Significant oxide-ionic conductivity has been recently reported for a family of cation-deficient hexagonal perovskite derivatives Ba3M2O8.5 (M = Mo/W6+ and Nb5+/V5+).

The A-site and oxygen-vacancy ordering in Sr 2 Nd Zn O 7 are inextricably linked, disrupting one would thus destroy the other. This compound is a mixed oxide ionic electronic conductor, exhibiting dominant conduction at elevated temperatures.
Abstract Generative Adversarial Networks (GANs) emerged thanks to the development of deep neural networks. Forgery images generated by various variants GANs are widely spread on Internet, which may be damage personal credibility and cause huge property losses. Thus, numerous methods proposed detect forgery images, but most them designed faces. Therefore, a method scenes is proposed. In this work, central difference convolution vanilla (CDC‐Mix) mixed after considering depth width features...
