| 1 | 3D carbon network supported porous SiOC ceramics with enhanced microwave absorption properties显示文摘Porous SiOC ceramic was successfully prepared by pyrolysis of dimethylsilicone oil,silane coupling agent and melamine foam.The microwave absorbing properties of porous SiOC were studied for the first time.At the matching layer thickness of 3.0 mm,the paraffin-based composite with porous SiOC displays a minimum reflection coefficient(RC)of-39.13 d B(11.76 GHz)and an effective absorption bandwidth(EAB)of 4.64 GHz which are much larger than that of paraffin-based composite with ordinary SiOC.It is found that the porous structure of SiOC is crucial to achieve its high microwave absorption performance by improving both the polarization loss and conduction loss.The enhanced polarization loss is originated from the dipole polarization and interfacial polarization,while the improvement of conduction loss is attributed to the carbon skeleton of porous SiOC.These results indicate that porous SiOC ceramic is a promising candidate for high-performance ceramic-based microwave absorbing materials. | Chen Chen Sifan Zeng Xiaochun Han Yongqiang Tan Wanlin Feng Huahai Shen Shuming Peng Haibin Zhang | 2020 | Journal of Materials Science & Technology2020，54，19： | 3 |

| 3 | Hybrid hydrovoltaic electricity generation driven by water evaporation显示文摘Water evaporation is a ubiquitous natural process exploiting thermal energy from ambient environment.Hydrovoltaic technologies emerged in recent years offer one prospective route to generate electricity from water evaporation,which has long been overlooked.Herein,we developed a hybrid hydrovoltaic generator driven by natural water evaporation,integrating an“evaporation motor”with an evaporation-electricity device and a droplet-electricity device.A rotary motion of the“evaporation motor”relies on phase change of ethanol driven by water-evaporation induced temperature gradient.This motion enables the evaporation-electricity device to work under a beneficial water-film operation mode to produce output of~4 V and~0.2μA,as well as propels the droplet-electricity device to convert mechanical energy into pulsed output of~100 V and~0.2 mA.As different types of hydrovoltaic devices require distinctive stimuli,it was challenging to make them work simultaneously,especially under one single driving force.We here for the first time empower two types of hydrovoltaic devices solely by omnipresent water evaporation.Therefore,this work presents a new pathway to exploiting water evaporation-associated ambient thermal energy and provides insights on developing hybrid hydrovoltaic generators. | Xuemei Li Gu Feng Yiding Chen Jidong Li Jun Yin Wei Deng Wanlin Guo | 2024 | Nano Research Energy2024，3，2： | 0 |
| 4 | YTHDF2-mediated regulations bifurcate BHPF-induced programmed cell deaths显示文摘N6-methyladenosine(m^(6)A)is a critical regulator in the fate of RNA,but whether and how m^(6)A executes its functions in different tissues remains largely obscure.Here we report downregulation of a crucial m^(6)A reader,YTHDF2,leading to tissue-specific programmed cell deaths(PCDs)upon fluorene-9-bisphenol(BHPF)exposure.Currently,Bisphenol A(BPA)substitutes are widely used in plastic manufacturing.Interrogating eight common BPA substitutes,we detected BHPF in 14%serum samples of pregnant participants.In a zebrafish model,BHPF caused tissue-specific PCDs triggering cardiac and vascular defects.Mechanistically,BHPF-mediated downregulation of YTHDF2 reduced YTHDF2-facilitated translation of m^(6)A-gch1 for cardiomyocyte ferroptosis,and decreased YTHDF2-mediated m^(6)A-sting1 decay for caudal vein plexus(CVP)apoptosis.The two distinct YTHDF2-mediated m^(6)A regulations and context-dependent co-expression patterns of gch1/ythdf2 and tnfrsf1a/ythdf2 contributed to YTHDF2-mediated tissue-specific PCDs,uncovering a new layer of PCD regulation.Since BHPF/YTHDF2-medaited PCD defects were also observed in mammals,BHPF exposure represents a potential health threat. | Jiebo Lin Guankai Zhan Jinfeng Liu Yasen Maimaitiyiming Zhiping Deng Baohua Li Kunhui Su Jiafeng Chen Siqi Sun Wanlin Zheng Xianghui Yu Feng He Xiaodong Cheng Lingfang Wang Bin Shen Ziqin Yao Xinquan Yang Jian Zhang Wentao He Hengyu Wu Hua Naranmandura Kao-Jung Chang Junxia Min Jun Ma Mikael Björklund Peng-Fei Xu Fudi Wang Chih-Hung Hsu | 2023 | National Science Review2023，10，12： | 0 |
| 5 | Five-channel frequency-division multiplexing using low-loss epsilon-near-zero metamaterial waveguide显示文摘The rapidly growing global data usage has demanded more efficient ways to utilize the scarce electromagnetic spectrum resource. Recent research has focused on the development of efficient multiplexing techniques in the millimeter-wave band(1-10 mm, or 30-300 GHz) due to the promise of large available bandwidth for future wireless networks. Frequency-division multiplexing is still one of the most commonly-used techniques to maximize the transmission capacity of a wireless network.Based on the frequency-selective tunnelling effect of the low-loss epsilon-near-zero metamaterial waveguide, we numerically and experimentally demonstrate five-channel frequency-division multiplexing and demultiplexing in the millimeter-wave range.We show that this device architecture offers great flexibility to manipulate the filter Q-factors and the transmission spectra of different channels, by changing of the epsilon-near-zero metamaterial waveguide topology and by adding a standard waveguide between two epsilon-near-zero channels. This strategy of frequency-division multiplexing may pave a way for efficiently allocating the spectrum for future communication networks. | Binbin Hong Lei Sun Wanlin Wang Yanbing Qiu Naixing Feng Dong Su Nutapong Somjit Ian Robertson Guo Ping Wang | 2022 | Science China(Physics,Mechanics & Astronomy)2022，65，7： | 0 |
