| 1 | Design and fabrication of superconducting HEB mixer显示文摘This paper describes the design and fabrication of superconducting hot electron bolometer (HEB) mixer based on ultra-thin superconducting NbN films. The high quality films were epitaxially grown on high resistance Si substrates. The device was fabricated by magnetron sputtering, electron beam lithography (EBL), reactive ion etching (RIE), lithography, and so on. The device's resistance-tempera-ture (R-T) curves and current-voltage (I-V) curves were studied. The results of THz response of the device are presented. Y-factor technique was used to measure the device's noise temperature. When the device was irradiated with a laser radiation of 2.5 THz, the obtained lowest noise temperature of the device was 2213 K. | WANG JinPing LI YangBin KANG Lin WANG Yu ZHONG YangYin LIANG Min CHEN Jian CAO ChunHai XU WeiWei WU PeiHeng | 2009 | Chinese Science Bulletin2009,54,12: | 5 |
| 2 | Gut microbiota-derived metabolites contribute negatively to hindgut barrier function development at the early weaning goat model显示文摘Early weaning induces intestinal injury,leading to a series of long-term symptoms such as inflammation,malabsorption and diarrhea.In this study,we hypothesized that microbes and theirmetabolitesmodulate the host's inflammatory response to early weaning stress in a goatmodel.A total of 18 female Tibetan goat kids(n?9)wereweaned fromtheirmothers at 28 d(D28)and 60 d(D60)postpartum.D60 and D28 groupswere fed the same solid diet ad libitum fromweaning to 75 d of age.The colonic epithelium was subject to RNAsequencing,the caecal digesta metabolomics were assessed by liquid chromatographyetandem mass spectrometry(LC-MS/MS),and the caecal microbiota composition was analysed by 16S ribosomal RNA gene sequencing.We foundthatearlyweaningsubstantially increased the colonic pro-apoptotic gene expressionof B-cell lymphoma associated X(Bax),caspase-9,and caspase-3,and decreased the expression of zonula occludens-1(ZO-1)and claudin-1(P<0.01).In addition,a significant Bacteroides acidifaciens enrichmentwas observed in the hindgut of early-weaned goats(P<0.01),which negatively correlated with lysophosphatidylcholine products.Similarly,the chemokine signaling,IL-17 signaling,and peroxisome proliferatorsactivated receptor(PPAR)signaling pathways were upregulated in the colonic mucosa of the early-weaned goats.By applying caecal microbiota transplantation from goats to defaunated C57/6J mice,we confirmed that caecalmicrobiota of D28 goat kids increased the relative abundance of B.acidifaciens and significantly upregulated the genes of Bax,G proteinecoupled receptor(GPR)109A,GPR 43,fatty acid binding protein 6,nuclear receptor subfamily 1 group H member 3,angiotensin converting enzyme 2,and IL-6 expression(P<0.05),and decreased ZO-1,and claudin-1 protein expression in the mice jejunum and colon(P<0.001).These results proposed that the hindgut microbiota andmetabolites mediate the barrier functionweakening duringearlyweaning,and the relative abundance of B.acidifacienswas negatively correlatedwiththe hindgut barrier gene expression.This studydemonstrateshowweaningstress canaffectkeyhostemicrobe interaction regulators in the hindgut,in a lysophosphatidylcholine dependent and independent manner.Furthermore,based on our mice data,these results are transferable to other mammal species. | Ke Zhang Yangbin Xu Yuxin Yang Mengmeng Guo Ting Zhang Bo Zong Shuhong Huang Langda Suo Baohua Ma Xiaolong Wang Yujiang Wu Daniel Brugger Yulin Chen | 2022 | Animal Nutrition2022,,3: | 2 |

| 6 | Dual-function perovskite light-emitting/sensing devices for optical interactive display显示文摘Interactive display devices integrating multiple functions have become a development trend of display technology.The excellent luminescence properties of perovskite quantum dots(PQDs)make it an ideal luminescent material for the next generation of wide-color gamut displays.Here we design and fabricate dual-function light-sensing/displaying light-emitting devices based on PQDs.The devices can display information as an output port,and simultaneously sense outside light signals as an input port and modulate the display information in a non-contact mode.The dual functions were attributed to the device designs:(1)the hole transport layer in the devices also acts as the light-sensing layer to absorb outside light signals;(2)the introduced hole trapping layer interface can trap holes originating from the light-sensing layer,and thus tune the charge transport properties and the light-emitting intensities.The sensing and display behavior of the device can be further modulated by light signals with different time and space information.This fusion of sensing and display functions has broad prospects in non-contact interactive screens and communication ports. | Songman Ju Yangbin Zhu Hailong Hu Yang Liu Zhongwei Xu Jinping Zheng Chaomin Mao Yongshen Yu Kaiyu Yang Lihua Lin Tailiang Guo Fushan Li | 2022 | Light(Science & Applications)2022,11,12: | 0 |
