130. Rational Design of a Core–Shelled Ti3AlC2@La2Zr2O7Composite for High-Temperature Broadband Microwave Absorption

Author

Abstract

Microwave-absorbing materials adapting to high temperatures and harsh environments are in great demand. Herein, a core–shelled Ti3AlC2@La2Zr2O7(TAC@LZO) composite was designed and fabricated by encapsulating the La2Zr2O7(LZO) thermal insulation ceramic on the surface of highly conductive Ti3AlC2(TAC) via chemical coprecipitation and subsequent heat treatment. The continuous LZO ceramic coating on the surface improved the oxidation resistance of the composite at 600 °C and modulated its dielectric properties. The TAC@LZO composite exhibited an excellent microwave absorption performance within the temperature range of 25–600 °C, minimum reflection loss (RLmin) < −55 dB, and effective absorption bandwidth (EAB, RL < −10 dB) of 4 GHz. This work presents an effective approach for developing stable high-temperature microwave absorbers from thermal insulation ceramics.

133. Scattering of surface traveling wave and its attenuation in absorbing coating.

Abstract

Surface traveling waves (STWs) contribute greatly to non-specular scattering, but their scattering and attenuation characteristics in an absorbing coating are unclear. Thus, the scattering peak angular location and the electromagnetic (EM) loss of the STWs are calculated. The results show that the thickness of an absorbing coating should be appropriate to achieve a large EM loss in wide frequency bandwidth, and the magnetic loss is dominant in the attenuation constant. Moreover, radar cross section (RCS) features of the STW and the effect of EM parameters' imaginary part on the RCS reduction of the STW at 6 GHz were investigated. The simulated results show that the wedge model can effectively excite the STW. Meanwhile, the permeability μ″ of the coating material has a more significant influence on the RCS reduction of the STW than the permittivity ɛ″. Furthermore, the simulated results were verified by the experimental results with an error of less than 20%. [ABSTRACT FROM AUTHOR]

Abstract

Boron carbide (B4C) has excellent high-temperature oxidation resistance, high hardness, low relative density, high melting point and excellent abrasive resistance, which is widely used in fields such as refractories, wear-resistant materials and lightweight protective materials. The research progress and application of B4C materials in China and overseas in recent years were summarized. The influences of sintering processes (pressureless sintering, hot-pressing sintering, hot isostatic pressing sintering, spark plasma sintering and microwave sintering) and sintering additives (simple substances, oxides and carbides) on the B4C densification were analyzed. The development of B4C materials was prospected. [ABSTRACT FROM AUTHOR]

Abstract

Electron backscatter diffraction (EBSD) can be employed to determine crystal structures but has not been used alone to identify defects at the atom scale due to the lack of understanding of the EBSD patterns generated by various structure defects. In the present work, the EBSD patterns of FCC‐Fe with 9‐layer, 6‐layer and 3‐layer twin structures are simulated, respectively, using the revised real space (RRS) method and compared with the counterpart of perfect crystals. Our results show that when the electron beam is incident along a direction parallel to the twin plane, the pattern appears symmetrical with respect to the corresponding Kikuchi band of the twin plane, and the diffraction details within the Kikuchi band also exhibit symmetry with respect to the middle line of the Kikuchi band. Moreover, the overall clarity of the patterns decreases, and the pattern becomes more blurred with increasing the distance from the Kikuchi band corresponding to the twin plane. By contrast, the incident electron beam along the direction perpendicular to the twin plane results in diffraction superposition of the matrix region and the shear region, which shows twofold rotational symmetry with respect to the Kikuchi pole corresponding to the normal to the twin plane. In addition, some extra Kikuchi bands appear in the EBSD patterns due to the long‐period structures of the multilayer twins. As the number of multilayer twins decreases, the number of extra Kikuchi bands decreases and the area of the blurring pattern increases. The correlation between twin structures and EBSD patterns provides theoretical insights for identifying twin structures by the EBSD technique. [ABSTRACT FROM AUTHOR]

Abstract

Recent advances in systemic and locoregional treatments for patients with unresectable or advanced hepatocellular carcinoma (HCC) have resulted in improved response rates. This has provided an opportunity for selected patients with initially unresectable HCC to achieve adequate tumor downstaging to undergo surgical resection, a 'conversion therapy' strategy. However, conversion therapy is a new approach to the treatment of HCC and its practice and treatment protocols are still being developed. Review the evidence for conversion therapy in HCC and develop consensus statements to guide clinical practice. Evidence review: Many research centers in China have accumulated significant experience implementing HCC conversion therapy. Preliminary findings and data have shown that conversion therapy represents an important strategy to maximize the survival of selected patients with intermediate stage to advanced HCC; however, there are still many urgent clinical and scientific challenges for this therapeutic strategy and its related fields. In order to summarize and learn from past experience and review current challenges, the Chinese Expert Consensus on Conversion Therapy for Hepatocellular Carcinoma (2021 Edition) was developed based on a review of preliminary experience and clinical data from Chinese and non-Chinese studies in this field and combined with recommendations for clinical practice. Sixteen consensus statements on the implementation of conversion therapy for HCC were developed. The statements generated in this review are based on a review of clinical evidence and real clinical experience and will help guide future progress in conversion therapy for patients with HCC.
