Abstract ：
The wideband absorption and transmission of frequency-selective rasorber (FSR) remain a persistent challenge in the application of radar devices. In this article, a novel high performance wideband FSR design based on cross bend resonators was proposed. The FSR consists of an upper absorption lossy layer, which offers broad absorption and transmission bands, and a lower bandpass frequency-selective surface that enables a highly selective transmission of incident electromagnetic wave. Full wave simulation results showed that this novel design achieves an absorption bandwidth of 83.7% with more than 90% absorptivity in the frequency range of 5.2-12.7 GHz. Furthermore, the passband's fractional bandwidth for the insertion loss (IL) less than -3 dB is 33.9%, ranging from 14.9 to 21 GHz, with the minimum IL recorded at 0.69 dB at 17.7 GHz. To further verify the proposed method, a prototype FSR with 10 x 10 units of 120 mm x 120 mm was fabricated and the performance of the FSR was tested. The experiment results were in good agreement with the simulated results, and it showed a significant monostatic radar cross-section reduction in the frequency range of 5.3 GHz to 18.3 GHz compared with a metallic plane of the same size.

Abstract ：
Adopting noble metals on non-noble metals is an effective strategy to balance the cost and activity of electrocatalysts. Herein, a thorough analysis of the synergistic OER is conducted at the heterogeneous interface formed by Ir clusters and NiCo2O4 based on DFT calculations. Specifically, the electrons spontaneously bring an e(g) occupancy of interfacial Ir close to unity after the absorbed O, providing more transferable electrons for the conversion of the absorbed O-intermediates. Besides, the diffuse distribution of electrons in the Ir 5d orbital fills the antibonding orbital after O is absorbed, avoiding the desorption difficulties caused by the stronger Ir-O bonds. The electrons transfer from Ir to Co atoms at the heterogeneous interface and fill the Co 3d band near the Fermi level, stimulating the interfacial Co to participate in the direct O-O coupling (DOOC) pathway. Experimentally, the ultrathin-modulated NiCo2O4 nanosheets are used to support Ir clusters (Ir-cluster-E-NiCo2O4) by the electrodeposition method. The as-synthesized Ir-cluster-E-NiCo2O4 catalyst achieves a current density of 10 mA cm(-2) at an ultralow overpotential of 238 mV and works steadily for 100 h under a high current of 100 mA cm(-2), benefiting from the efficient DOOC pathway during the OER.

Abstract ：
采用基于密度泛函理论的投影平面波方法,对Ruddlesden-Popper(RP)层状钙钛矿结构Bi8Ba4Mn8O28的电子结构和磁学性质进行了自旋极化计算.由于A位Ba的替位掺杂,造成MnO6八面体发生显著旋转、倾斜等畸变,会对电子结构与磁性产生较大影响,对此进行了充分的讨论.考虑在位库伦作用修正的广义梯度近似(GGA+U)的计算表明,Bi8Ba4Mn8O28基态为铁磁半金属,其半金属能隙3.07 eV,晶胞总磁矩为31μB.Bi8Ba4Mn8O28的晶胞磁矩主要来自Mn原子磁矩的贡献,而Bi、Ba与O原子磁矩相对较小;而半金属性则主要源于Mn 3d自旋向上与自旋向下电子间存在较大的交换劈裂所致.使晶胞承受均匀变形,当其晶格常数在-10％～14％较大范围变化时,半金属性均可得到保持,且其晶胞总磁矩可始终稳定于31μB.

Abstract ：
The distinctive characteristics of alloy catalysts, encompassing composition, structure, and modifiable adsorption sites, present significant potential for the development of highly efficient electrocatalysts for oxygen evolution/reduction reactions [oxygen evolution reactions (OERs)/oxygen reduction reactions (ORRs)]. Machine learning (ML) methods can quickly establish the relationship between material features and catalytic activity, thus accelerating the development of alloy electrocatalysts. However, the current abundance of features presents a crucial challenge in selecting the most pertinent ones. In this study, we explored seven intrinsic features directly derived from the material's structure, with a specific focus on the chemical environment of active sites and their nearest neighbors. An accurate and efficient ML model to predict potential bifunctional oxygen electrocatalysts based on the intrinsic features of AB-type alloy active sites and intermediate free energies in the OERs/ORRs was established. These features possess clear physical and chemical meanings, closely linked to the electronic and geometric structures of active sites and neighboring atoms, thereby providing indispensable insights for the discovery of high-performance electrocatalysts. The ML model achieved R-2 scores of 0.827, 0.913, and 0.711 for the predicted values of the three intermediate (OH, O, OOH) free energies, with corresponding mean absolute errors of 0.175, 0.242, and 0.200 eV, respectively. These results indicate that the ML model exhibits high accuracy in predicting the intermediate free energies. Furthermore, the ML model exhibited a prediction efficiency 150,000 times faster than traditional density functional theory calculations. This work will offer valuable insights and a framework for facilitating the rapid design of potential catalysts by ML methods.

Abstract ：
Selective infrared radiation is crucial for achieving infrared stealth and heat dissipation. Artificially designed superstructure film (SF) provides several advantages for controlling and modulating infrared radiation, making them a promising solution for these applications. The research described in this work has successfully produced broadband selective infrared radiation by using a surface made up of circular patches that are combined. Numerical simulations show that this SF can achieve broadband selective radiation with 3-5 mu m mid-wave infrared (MWIR) suppression and 8-14 mu m long-wave infrared (LWIR) emission. The spectral selectivity can be easily switched to high emissivity in MWIR and low emissivity in LWIR by simply changing the basal layer. The resonance mechanism for achieving broadband spectral selectivity in the SF may be due to a combination of multimode plasmon resonances that are induced by the structural nonrotational symmetry of the circular patches. By applying the selective radiation SF on the tail nozzle or the vehicle, the effect of thermal management is very significant. Selective radiation SF can reduce radiant energy in the 3-5 mu m band by a significant amount at 500 degrees C, resulting in a 46 degrees C cooler temperature than that at the body without the SF. At 80 degrees C, radiated energy in the 8-14 mu m band is also considerably reduced and the temperature is 10 degrees C lower than that of the body without the SF. There will be obvious advantages in potential applications for infrared stealth and heat dissipation by the designed SF, a simple and convenient manufacturing process.
