Layered rare-earth metal oxides, harnessing the dual properties of oxides and two-dimensional layered materials, exhibit remarkable thermal stability and quantum confinement effects. Therefore, this work adopts the first-principles calculation combined with the Boltzmann transport theory to predict the thermoelectric properties of NdZnSbO compound. The coexistence of weak interlayer van der Waals interactions, robust intralayer ionic bonding, and partial covalent bonding leads to remarkable bonding heterogeneity, which engenders pronounced phonon scattering and imposes constraints on thermal transport along the out-of-plane direction. The weakened chemical bonds induced by the antibonding states, together with the rattling-like behavior of the Zn atom, culminate in the profound anharmonicity in the layered NdZnSbO compound. The weakening bond and heavy element contribute to the softness of phonon modes, which significantly diminishes the phonon group velocity. The redistribution-dominated four-phonon scattering process spans a large optical gap, which effectively reduces the lattice thermal conductivity. The NdZnSbO compound exhibits direct semiconductor characteristic with a bandgap of 0.73 e V by adopting the Heyd-Scuseria-Ernzerhof(HSE06) functional in combination with spin–orbit coupling(SOC) effect. The multi-valley feature of NdZnSbO compound augur favorably for band degeneracy, thus amplifying the power factor. Consequently, an optimal figure-of-merit(ZT) of 3.40 at 900 K is achieved for the n-type NdZnSbO compound. The present study delves deeply insights into the origins for the low thermal conductivity of NdZnSbO compound and proposes an optimization scheme to enhance overall thermoelectric performance.

A novel elastic metamaterial is proposed with the aim of achieving lowfrequency broad bandgaps and bandgap regulation. The band structure of the proposed metamaterial is calculated based on the Floquet-Bloch theorem, and the boundary modes of each bandgap are analyzed to understand the effects of each component of the unit cell on the bandgap formation. It is found that the metamaterials with a low elastic modulus of ligaments can generate flexural wave bandgaps below 300 Hz. Multi-frequency vibrations can be suppressed through the selective manipulation of bandgaps. The dual-graded design of metamaterials that can significantly improve the bandgap width is proposed based on parametric studies. A new way that can regulate the bandgap is revealed by studying the graded elastic modulus in the substrate. The results demonstrate that the nonlinear gradient of the elastic modulus in the substrate offers better bandgap performance. Based on these analyses, the proposed elastic metamaterials can pave the way for multi-frequency vibration control, low-frequency bandgap broadening, and bandgap tuning.

目的明确DEPTOR在直肠癌组织中的表达情况,并进一步探讨DEPTOR的表达水平与病理组织学及预后的关系,以期为直肠癌的临床诊疗提供参考。方法回顾性分析2011年1月至2013年1月在我院接受直肠癌根治术的102例患者的临床资料。所有患者采用免疫组化及免疫印迹法评估癌组织及癌旁组织DEPTOR的表达,计算光密度值(IOD)并依据DEPTOR的IOD中位数将患者分为DEPTOR高表达组及低表达组;分析DEPTOR的表达水平与临床、病理组织学及预后的关系。结果免疫组化和免疫印迹法显示,DEPTOR在癌组织中的表达水平显著高于癌旁组织,差异有统计学意义(P 0. 05);而在肿瘤直径、T分期、N分期及分化程度上比较差异有统计学意义(P 0. 05); Spearman相关性分析显示,直肠癌患者DEPTOR表达水平与血清CEA水平呈显著正相关(r=0. 509,P <0. 01)。DEPTOR高表达组5年累积复发率高于低表达组,其5年累积死亡率高于低表达组(P <0. 05)。结论 DEPTOR在直肠癌中高表达且与疾病进展程度相关,其升高提示预后不良。
