| 1 | Disruption of adipocyte HIF-1α improves atherosclerosis through the inhibition of ceramide generation显示文摘Atherosclerosis is a chronic multifactorial cardiovascular disease.Western diets have been reported to affect atherosclerosis through regulating adipose function.In high cholesterol diet-fed ApoE^(−/−)mice,adipocyte HIF-1αdeficiency or direct inhibition of HIF-1αby the selective pharmacological HIF-1αinhibitor PX-478 alleviates high cholesterol diet-induced atherosclerosis by reducing adipose ceramide generation,which lowers cholesterol levels and reduces inflammatory responses,resulting in improved dyslipidemia and atherogenesis.Smpd3,the gene encoding neutral sphingomyelinase,is identified as a new target gene directly regulated by HIF-1αthat is involved in ceramide generation.Injection of lentivirus-SMPD3 in epididymal adipose tissue reverses the decrease in ceramides in adipocytes and eliminates the improvements on atherosclerosis in the adipocyte HIF-1α-deficient mice.Therefore,HIF-1αinhibition may constitute a novel approach to slow atherosclerotic progression. | Pengcheng Wang Guangyi Zeng Yu Yan Song-yang Zhang Yongqiang Dong Yangming Zhang Xingzhong Zhang Huiying Liu Zhipeng Zhang Changtao Jiang Yanli Pang | 2022 | Acta Pharmaceutica Sinica B2022，12，4： | 6 |
| 2 | Digital Light Processing 3D-Printed Ceramic Metamaterials for Electromagnetic Wave Absorption显示文摘Combining 3D printing with precursor-derived ceramic for fabricating electromagnetic(EM) wave-absorbing metamaterials has attracted great attention. This study presents a novel ultraviolet-curable polysiloxane precursor for digital light processing(DLP) 3D printing to fabricate ceramic parts with complex geometry, no cracks and linear shrinkage. Guiding with the principles of impedance matching, attenuation, and effective-medium theory, we design a crosshelix-array metamaterial model based on the complex permittivity constant of precursor-derived ceramics. The corresponding ceramic metamaterials can be successfully prepared by DLP printing and subsequent pyrolysis process, achieving a low reflection coefficient and a wide effective absorption bandwidth in the X-band even under high temperature. This is a general method that can be extended to other bands, which can be realized by merely adjusting the unit structure of meta-materials. This strategy provides a novel and effective avenue to achieve “target-design-fabricating” ceramic metamaterials, and it exposes the downstream applications of highly efficient and broad EM wave-absorbing materials and structures with great potential applications. | Rui Zhou Yansong Wang Ziyu Liu Yongqiang Pang Jianxin Chen Jie Kong | 2022 | Nano-Micro Letters2022，14，7： | 4 |
| 3 | Mechanism of Silurian Hydrocarbon Pool Formation in the Tarim Basin显示文摘There are three formation stages of Silurian hydrocarbon pools in the Tarim Basin. The widely distributed asphaltic sandstones in the Tazhong (central Tarim) and Tabei (northern Tarim) areas are the results of destruction of hydrocarbon pools formed in the first-stage,and the asphaltic sandstones around the Awati Sag were formed in the second-stage. The hydrocarbon migration characteristics reflected by the residual dry asphalts could represent the migration characteristics of hydrocarbons in the Silurian paleo-pools,while the present movable oil in the Silurian reservoirs is related to the later-stage (the third-stage) hydrocarbon accumulation. | Liu Luofu Chen Yuanzhuang Chen Lixin Pang Xiongqi Xie Qilai Huo Hong Zhao Suping Li Chao Li Shuangwen Guo Yongqiang Zhao Yande Li Yan | 2007 | Petroleum Science2007，4，4： | 2 |

| 9 | Shape memory alloy-based 3D morphologically reconfigurable chiral metamaterial for tailoring circular dichroism by voltage control显示文摘Three-dimensional chiral materials with intrinsic chirality play a crucial role in achieving a strong chiral response and flexible light manipulation.Reconfigurable chirality through the 3D morphological transformation of chiral materials is significant for greater freedom in tailoring light but remains a challenge.Inspired by the unique 3D morphological memory capability of shape memory alloys(SMAs),we demonstrate and discuss a chiral resonator in the microwave regime that can realize reconfigurable chirality through 3D morphological transformation.The introduction of heating film realizes voltage control of SMA’s morphology for utilizing the temperature sensitivity of SMA better,enabling arbitrary control of circular dichroism(CD)flip and CD intensity.The qualitative and quantitative analysis of the surface current distribution of chiral enantiomers reveals that the chirality of metaatoms originates from the surge of electric dipole pxand electric quadrupole Q.It is worth mentioning that the proposed strategy to achieve reconfigurable chirality using 3D morphological transformations can be directly extended to other higher frequencies,such as visible,infrared,and terahertz bands.Significantly,our paradigm to study the relationship between complex 3D morphology and chirality holds potential for application in biosensing,spin detection,and spin-selective devices. | LIXIN JIANG QI YUAN HAO YANG YONGFENG LI LIN ZHENG ZHIBIAO ZHU SHUANG LIANG YONGQIANG PANG HE WANG JIAFU WANG SHAOBO QU | 2023 | Photonics Research2023，11，3： | 0 |
| 10 | Switchable chiral mirror based on PIN diodes显示文摘Chiral mirrors can produce spin selective absorption for left-handed circularly polarized(LCP) or right-handed circularly polarized(RCP) waves. However, the previously proposed chiral mirror only absorbs the designated circularly polarized(CP) wave in the microwave frequency band, lacking versatility in practical applications.Here, we propose a switchable chiral mirror based on a pair of PIN diodes. The switchable chiral mirror has four working states, switching from the handedness-preserving mirror to the LCP mirror, RCP mirror, and perfect absorber. The basis of these advances is to change the chirality of two-dimensional(2D) chiral metamaterials and the circular conversion dichroism related to it, which is the first report in the microwave frequency band.Surface current distributions shed light on how switchable chiral mirrors work by handedness-selective excitation of reflective and absorbing electric dipole modes. Energy loss distributions verify the working mechanism. The thickness of the switchable chiral mirror is one-tenth of the working wavelength, which is suitable for integrated manufacturing. The measurement results are in good agreement with the simulation results. | ZHIBIAO ZHU ZHE QIN HE WANG LIXIN JIANG YONGFENG LI WENJIE WANG HONGYA CHEN JIAFU WANG YONGQIANG PANG SHAOBO QU | 2023 | Photonics Research2023，11，7： | 0 |
| 11 | Finite element analysis of an all-steel buckling-restrained brace显示文摘Typical all-steel buckling-restrained braces(BRBs)usually exhibit obvious local buckling,which is attributed to the lack of longitudinal restraint to the rectangle core plate.To address this issue,all-steel BRBs are proposed,in which two T-shaped steel plates are adopted as the minor restraint elements to restrain the core plate instead of infilled concrete or mortar.In order to investigate the factors that characterize the hysterical responses of this device,different finite element(FE)models are developed for the specific context.The FE models are developed based on nonlinear finite element software,which incorporate continuum(shell or brick)elements,large displacement,and deformation formulations.In these FE models,two different steel constitutive models are adopted to precisely reproduce the cyclic response of the BRB component.Meanwhile,comparisons between the numerical and experimental results are conducted to validate the effectiveness and accuracy of the robust FE model.The agreements between experimental observations and numerical predictions demonstrate that the FE method could be utilized for in depth parametric analysis.Furthermore,BRBs with detailed configurations can provide excellent hysteretic behavior and seismic performance through the optimal design process. | Jiang Tao Dai Junwu Yang Yongqiang Bai Wen Pang Hui Liu Rongheng | 2022 | Earthquake Engineering and Engineering Vibration2022，21，4： | 0 |
| 12 | A reflective-backing-free metamaterial absorber with broadband response显示文摘In this paper,we propose a polarization-independent and broadband perfect infrared(IR)metamaterial absorber(MA)without reflective backing.The proposed absorber is a periodic meta-atom array consisting of metal-dielectric-multilayer truncated cones which can absorb 80%EM wave from 50.70 to 81.87 THz,while transmit 80%EM wave from 0 to 37.71 THz.With the decreasing of frequency,the transmissivity increases,which is close to 100%from 0 to 5 THz.We can broaden the absorption bandwidth of the MA by cascading multi-layers truncated cones.Furthermore,the proposed IR MA promises to be one desirable stealth material for radar-IR compatibility. | Cuilian Xu Shaobo Qu Jiafu Wang Mingbao Yan Yongqiang Pang Wenjie Wang Hua Ma | 2017 | Journal of Advanced Dielectrics2017，7，3： | 0 |
| 13 | Optical transparent infrared high absorption metamaterial absorbers显示文摘In this work,an optical transparent infrared high absorption metamaterial absorber is proposed based on indium tin oxide(ITO)substrate.Due to the fact that ITO holds high reflectivity property in infrared region while transparent in optical region,ITO can be used in the application of Surface Plasmon Polaritons.In this design,three kinds of infrared metamaterial absorbers were proposed.All of them can achieve high absorption at 10.6μm while remaining transparent in visible region.LC equivalent circuit model was served as design foundation.The infrared absorption efficiency was numerically calculated and the mechanism analysis is given in the paper.The simulation results show that all three structures can achieve high absorption efficiency at 10.6μm under TE/TM polarization.The absorption remains high when the incident angle is less than 70°.Experimental results exhibit good accordance with simulation. | Jingfan Yang Cuilian Xu Shaobo Qu Hua Ma Jiafu Wang Yongqiang Pang | 2018 | Journal of Advanced Dielectrics2018，8，1： | 0 |
