| 8 | No tillage outperforms conventional tillage under arid conditions and following fertilization显示文摘Reduced tillage practices present a tool that could sustainably intensify agriculture.The existing literature,however,lacks a consensus on how and when reduced tillage practices should get implemented.We reanalyzed here an extensive dataset comparing how regular tillage practices(i.e.,conventional tillage)impacted yield of eight crops compared to stopping tillage altogether(i.e.,no-tillage practice).We observed that aridity and fertilization favored no tillage over conventional tillage whereas conventional tillage performed better under high fertility settings.We further show that the responses are consistent across the crops.Our reanalysis complements the original and fills a gap in the literature questioning the conditions under which reducing tillage presents a viable alternative to common tillage practices. | Stavros D.Veresoglou Junjiang Chen Xuheng Du Qi Fu QingLiu Geng Chenyan Huang Xilin Huang Nan Hu Yiming Hun Guolin C.Li Zhiman Lin Zhiyu Ma Yuyi Ou Shuo Qi Haitian Qin Yingbo Qiu Xibin Sun Ye Tao YiLing Tian Jie Wang Lingxiao Wu Ziwei Wu Siqi Xie Ao Yang Dan Yang Chen Zeng Ying Zeng RuJie Zhang | 2023 | Soil Ecology Letters2023，5，1： | 1 |
| 9 | Synthesis and Structure of trans-1,2-Bisaromatic Heterocycle Substituted Cyclopropanes显示文摘Trans-1,2-bis(2’-(5 ’-phenyl-1 ’,3’,4’-oxadiazolyl)) cyclopropane (BDCP) and its eleven substituted novel derivatives were synthesized. Besides four derivatives of l,2-bis(2’-(5’-phenyl-l ’ , 3 ’ , 4 ’ -ox-adiazo1yl))ethane (BPDS) were also synthesized as model compounds. The crystal structure of ethyl BDCP was determined and the cyclopropane ring was found to be able to transmit conjugation between the aromatic groups directly bonding with it by studying the ultraviolet and fluorescent spectra of the above compounds. | Wang Changsheng, Pan Jiaxing and Gao Zhenheng (Department of Chemistry, Nankai University, Tianjin) Yao Xinkan, Wang Ruji and Wang Honggen (Central Laboratory, Nankai University, Tianjin) | 1989 | Chemical Research in Chinese Universities1989，5，1： | 0 |
| 10 | 3D Printed Antennas for 5G Communication:Current Progress and Future Challenges显示文摘With the advent of 5G and future trends for communication systems moving to millimeter wave(MMW)and higher frequencies,antennas will be required to have high gain,wide bandwidth,and low losses.3D printing realizes structures by sequential stacking layer-by-layer,which enables the manufacturing of antennas with ar-bitrary shapes in a cheaper,faster,and flexible manner.This study provides a review of current state-of-the-art 3D printed antennas for different frequencies.First,an overview of 3D printing technology is presented.A huge number of 3D printed antennas,categorized by their material composition,have been described,including poly-mer,metallic,ceramic,composite material,and multi-material integrated antennas.Finally,the main challenges and prospects are discussed to provide insight into how 3D printing can be further progressed in antenna manu-facturing. | Yaru Wang Xueqin Zhang Ruyue Su Mingji Chen Chujing Shen Hao Xu Rujie He | 2023 | Chinese Journal of Mechanical Engineering(Additive Manufacturing Frontiers)2023，2，1： | 0 |
| 11 | Antagonizing exosomal miR-18a-5p derived from prostate cancer cells ameliorates metastasis-induced osteoblastic lesions by targeting Hist1h2bc and activating Wnt/β-catenin pathway显示文摘More than 50%of prostate cancer(PCa)patients have bone metastasis with osteo-blastic lesions.MiR-18a-5p is associated with the development and metastasis of PCa,but it remains unclear whether it is involved in osteoblastic lesions.We first found that miR-18a-5p was highly expressed in the bone microenvironment of patients with PCa bone metastases.To address how miR-18a-5p affects PCa osteoblastic lesions,antagonizing miR-18a-5p in PCa cells or pre-osteoblasts inhibited osteoblast differentiation in vitro.Moreover,injection of PCa cells with miR-18a-5p inhibition improved bone biomechanical properties and bone mineral mass in vivo.Furthermore,miR-18a-5p was transferred to osteoblasts by exosomes derived from PCa cells and targeted the Hist1h2bc gene,resulting in Ctnnb1 up-regulation in the Wnt/β-catenin signaling pathway.Translationally,antagomir-18a-5p significantly improved bone biomechanical properties and alleviated sclerotic lesions from osteoblastic me-tastases in BALB/c nude mice.These data suggest that inhibition of exosome-delivered miR-18a-5p ameliorates PCa-induced osteoblastic lesions. | Fanchun Zeng Chunrong Zhao Rujie Wang Lingyan Ren Hao Qiu Zhi Zou Haibin Ding Zhongyi Sun Jianmei Li Shiwu Dong | 2023 | Genes & Diseases2023，10，4： | 0 |
| 12 | 3D-printed strontium-incorporatedβ-TCP bioceramic triply periodic minimal surface scaffolds with simultaneous high porosity,enhanced strength,and excellent bioactivity显示文摘In bone tissue engineering,scaffolds with excellent mechanical and bioactive properties play prominent roles in space maintaining and bone regeneration,attracting increasingly interests in clinical practice.In this study,strontium-incorporatedβ-tricalcium phosphate(β-TCP),named Sr-TCP,bioceramic triply periodic minimal surface(TPMS)structured scaffolds were successfully fabricated by digital light processing(DLP)-based 3D printing technique,achieving high porosity,enhanced strength,and excellent bioactivity.The Sr-TCP scaffolds were first characterized by element distribution,macrostructure and microstructure,and mechanical properties.Notably,the compressive strength of the scaffolds reached 1.44 MPa with porosity of 80%,bringing a great mechanical breakthrough to porous scaffolds.Furthermore,the Sr-TCP scaffolds also facilitated osteogenic differentiation of mouse osteoblastic cell line(MC3T3-E1)cells in both gene and protein aspects,verified by alkaline phosphatase(ALP)activity and polymerase chain reaction(PCR)assays.Overall,the 3D-printed Sr-TCP bioceramic TPMS structured scaffolds obtained high porosity,boosted strength,and superior bioactivity at the same time,serving as a promising approach for bone regeneration. | Yanbo Shan Yang Bai Shuo Yang Qing Zhou Gang Wang Biao Zhu Yiwen Zhou Wencan Fang Ning Wen Rujie He Lisheng Zhao | 2023 | Journal of Advanced Ceramics2023，12，9： | 0 |
| 13 | Accuracy controlling and mechanical behaviors of precursor-derived ceramic SiOC microlattices by projection micro stereolithography(PμSL)3D printing显示文摘Precursor-derived ceramic SiOC(PDC-SiOC)microlattices exhibit excellent oxidation resistance,high-temperature stability,and superior mechanical properties.However,the printing accuracy of the PDC-SiOC microlattices by 3D printing is still limited,and mechanical properties of the PDC-SiOC microlattices have not been studied systematically.Here,PDC-SiOC octet microlattices were fabricated by projection micro stereolithography(PμSL)3D printing,and photoabsorber(Sudan III)’s effect on the accuracy was systematically analyzed.The results showed that the addition of Sudan III improved the printing accuracy significantly.Then,the ceramization process of the green body was analyzed in detail.The order of the green body decreased,and most of their chemical bonds were broken during pyrolysis.After that,the PDC-SiOC microlattices with different truss diameters in the range of 52–220μm were fabricated,and their mechanical properties were investigated.The PDC-SiOC microlattices with a truss diameter of 52μm exhibited higher compression strength(31 MPa)than those with bigger truss diameters.The size effect among the PDC-SiOC microlattices was analyzed.Our work provides a deeper insight into the manufacturing of PDC-SiOC micro-scaled architectures by 3D printing and paves a path to the research of the size effect in ceramic structures. | Ruyue Su Jingyi Chen Xueqin Zhang Xiong Gao Wenqing Wang Ying Li Rujie He | 2023 | Journal of Advanced Ceramics2023，12，11： | 0 |
