Retrosynthetic analysis of modestly complex molecules has been automated over the course of decades, but the combinatorial explosion of route possibilities has challenged computer hardware and software until only recently. Here, we explore a computational strategy that merges computer-aided synthesis planning with molecular graph editing to minimize the number of synthetic steps required to produce alkaloids.Asymmetric counteranion-directed photoredox catalysisbuduichengfanyinlizidingxiangguangyanghuahuanyuancuihua▲ zuozhe:SAYANTANI DAS, CHENDAN ZHU, DERYA DEMIRBAS, ECKHARD BILL, CHANDRA KANTA DE, AND BENJAMIN▲ lianjie:https://www.science.org/doi/10.1126/science.ade8190▲ zhaiyao:guangyanghuahuanyuancuihuayaoliyongguangyoudaodefasetuanhediwuzhijiandedianzizhuanyilaicujinhuaxuefanyingxing。zaidiwuyufasetuanbuxiediaodeqingkuangxia,kongzhilitixuanzexingkenengjuyoutiaozhanxing。zuozhebaodaoliaoyizhonggaodulitixuanzedefangfa,jiangyanglizifasetuanyushouxingyinlizipeidui。zaifasetuanhuanyuanhou,yinliziyuhuohuadediwupeidui,zaizhezhongqingkuangxia,yanghuabenyixiyanshengwukejinxing[2+2]huanjiacheng,congeryouliyuliangzhongqianzaijingxiangchanwuzhongyizhongdexingcheng。▲ Abstract:Photoredox catalysis enables distinctive and broadly applicable chemical reactions, but controlling their selectivity has proven to be difficult. The pursuit of enantioselectivity is a particularly daunting challenge, arguably because of the high energy of the activated radical (ion) intermediates, and previous approaches have invariably required pairing of the photoredox catalytic cycle with an additional activation mode for asymmetric induction. A potential solution for photoredox reactions proceeding via radical ions would be catalytic pairing with enantiopure counterions. However, although attempts toward this approach have been described, high selectivity has not yet been accomplished. Here we report a potentially general solution to radical cation–based asymmetric photoredox catalysis. We describe organic salts, featuring confined imidodiphosphorimidate counteranions that catalyze highly enantioselective [2+2]-cross cycloadditions of styrenes.A room temperature rechargeable Li2O-based lithium-air battery enabled by a solid electrolyteyougutidianjiezhiqudongdeshiwenkechongdianzuokongqidianchi▲ zuozhe:ALIREZA KONDORI, MOHAMMADREZA ESMAEILIRAD, AND MOHAMMAD ASADI▲ lianjie:https://www.science.org/doi/10.1126/science.abq1347▲ zhaiyao:zainengliangmidufangmian,zuokongqidianchiyounengliyuqiyoudianchijingzheng。raner,zaidaduoshutixizhong,fanyingtujingyaomeshejiyigehuolianggedianzizhuanyi,fenbiedaozhiguoyanghuazuo(Li2O2)huochaoyanghuawuzuo(LiO2)。zuozheyanjiuliaoyizhongshiyongtaoci-juyixiyanghuawujifuhegutidianjiezhidezuo-kongqidianchi,faxiantakeyitongguozuoyanghuawu(Li2O)dexingchenghefenjiejinxingsidianziyanghuahuanyuanfanying。gaifuhedianjiezhitongguosidianzizhuanyiguochengbiaoxianchujiaogaodelizidaodianxinghewendingxing。▲ Abstract:Lithium-air batteries have scope to compete with gasoline in terms of energy density. However, in most systems, the reaction pathways either involve one- or two-electron transfer, leading to lithium peroxide (Li2O2) or lithium superoxide (LiO2), respectively. Kondori et al. investigated a lithium-air battery that uses a ceramic-polyethylene oxide–based composite solid electrolyte and found that it can undergo a four-electron redox reaction through lithium oxide (Li2O) formation and decomposition. The composite electrolyte embedded with Li10GeP2S12 nanoparticles shows high ionic conductivity and stability and high cycle stability through a four-electron transfer process.diqiuwulixueGeophysicsSmoke-weather interaction affects extreme wildfires in diverse coastal regionsyan-tianqixianghuzuoyongyingxiangbutongyanhaidiqudejiduanyehuo▲ zuozhe:XIN HUANG, KE DING, JINGYI LIU, ZILIN WANG, RONG TANG, LIAN XUE, HAIKUN WANG, QIANG ZHANG, ZHE-MIN TAN, AND AIJUN DING▲ lianjie:https://www.science.org/doi/10.1126/science.add9843▲ zhaiyao:jiduanyehuoweixiezhuorenleishengming、kongqizhiliangheshengtaixitong。zuozhezhanshiliaotianqichidufankuizaidizhonghaihemeiguoxihaianhedongnanyajifengqihoutixizhongduiqudongjiduanhuozaideshouyaozuoyong。tamenfaxian,yanwuqirongjiaodefushexiaoyingkeyigaibianjindibiaofeng、kongqiganzaohejiangyu,congertongguozengqianghuoyanpaifangyijixiaoruokuosanjiajukongqiwuran。yehuo、yanwuhetianqizhijiancuozongfuzadexianghuzuoyongxingchengliaoyigezhengfankuixunhuan,dadazengjialiaokongqiwurandebaolu。▲ Abstract:Extreme wildfires threaten human lives, air quality, and ecosystems. Here, we show the primacy of synoptic-scale feedback in driving extreme fires in Mediterranean and monsoon climate regimes in the West Coast of the United States and Southeastern Asia. We found that radiative effects of smoke aerosols can modify near-surface wind, air dryness, and rainfall and thus worsen air pollution by enhancing fire emissions and weakening dispersion. The intricate interactions among wildfires, smoke, and weather form a positive feedback loop that substantially increases air pollution exposure.The magmatic web beneath Hawai‘ixiaweiyidibiaoxiadeyanjiangwang▲ zuozhe:JOHN D.

Although Ki?lauea is currently by far the most active, the other volcanoes could still erupt as well. Wilding et al. used more than 200,000 seismic events to map out the geometry of the magma feeding into these volcanoes at a 40-kilometer depth (see the Perspective by Flinders). The magma forms a sill complex that connects Ki?lauea and Mauna Loa, and there is some evidence of connection to Mauna Kea. The observations suggest far greater underground connections between the volcanoes and provide an interesting insight into magma transport.wulixuePhysicsMedium-density amorphous icezhongmidufeijingbing▲ zuozhe:ALEXANDER ROSU-FINSEN, MICHAEL B.

A substantial density gap between low-density and high-density amorphous ice with liquid water in the middle is a cornerstone of our current understanding of water. However, we show that ball milling “ordinary” ice Ih at low temperature gives a structurally distinct medium-density amorphous ice (MDA) within this density gap. These results raise the possibility that MDA is the true glassy state of liquid water or alternatively a heavily sheared crystalline state. Notably, the compression of MDA at low temperature leads to a sharp increase of its recrystallization enthalpy, highlighting that H2O can be a high-energy geophysical material.

24层楼高!首艘国产大型邮轮“爱达·魔都”号出坞,计划年底交付2023-06-07 06:22·环球网来源:环球时报【环球时报 记者 杨沙沙 褚大业 环球时报特约记者 赵乾坤】6月6日,由中国船舶外高桥造船有限公司建造的我国首艘国产大型邮轮“爱达·魔都”号出坞,标志着国产大型邮轮项目全面开启码头系泊试验、出海试航和交付的周期。这艘邮轮于2019年开始建造,计划于2023年年底交付。出坞是指将完成建造工作的船在坞内浮于水面,并将它引出坞外停在码头的作业。对于邮轮来说,具备出坞的条件,也就意味着船上的主要核心设备和管路基本安装完毕。“爱达·魔都”号的船东为中船嘉年华邮轮有限公司(简称“中船嘉年华”)。中船嘉年华是由全球最大造船集团中国船舶集团与全球最大邮轮集团嘉年华集团于2018年在中国成立的合资公司。6日,中船嘉年华发给《环球时报》记者的信息显示,“爱达·魔都”号全长达323.6米,总吨位达13.55万吨,总高约等于24层楼,可搭载乘客5246人。该邮轮拥有客房2125间,在超过4万平方米(将近6个标准足球场)总计16层的生活娱乐区域,设有大型演艺中心、大型餐厅、特色餐馆等休闲娱乐场所,还有海上最大的免税店以及5G信号覆盖的超五星级酒店。“17年以来,只有国外邮轮在中国经营。”中国交通运输协会邮轮游艇分会常务副会长兼秘书长郑炜航6日接受《环球时报》记者采访时表示,“爱达·魔都”号对中国邮轮制造业来说是从0到1、从无到有的突破,意义重大。航空母舰、大型邮轮、大型液化天然气(LNG)运输船被誉为世界造船业皇冠上的“三颗明珠”,代表当今全球船舶工业最高水平。作为设计建造难度最高的船型之一,大型邮轮是我国目前唯一未攻克的高技术、高附加值产物。据了解,“爱达·魔都”号整船零部件数量达到2500万个,相当于C919大飞机的5倍、“复兴”号高铁的13倍;全船总电缆布置长度达到4200公里,相当于上海至拉萨的距离。香港《南华早报》评论称,被称为“浮动城市”的邮轮是全球最难建造和最复杂的船只之一。中国首次涉足大型邮轮的先进制造工艺,是一个里程碑。中国国产邮轮制造在国际上处于什么水平?郑炜航认为,与德国、意大利、法国、芬兰相比,国产邮轮制造业还是“小学生”,处于一个学习、消化的阶段。资深航运专家吴明华6日接受《环球时报》记者采访时表示,“爱达·魔都”号是中国造船业学习欧洲造船领先技术的试水船,目前只能说邮轮建造“零”的突破,其建造技术、船舶性能、核心配套设施、操控能力等,有待4到5年的航行记录来检验。骆小平万分难过,夫妻一场说散就散。这世上哪有真正可以相依的人。...拟聘用人选公示 - 广西柳州市人力资源和社会保障...
