The silicon (3560 mAh/g) anode delivers a 10-times-higher specific capacity than that of the graphite counterpart (372 mAh/g).However,the large volume change of Si during lithiation and de-lithiation processes always result in poor cycling stability.Lots of studies have been focused on the nanoengineering of Si [1],but the high cost,complex fabrication,poor initial coulombic efficiency (iCE)and calendar life limit its commercial-ization.

Privacy-preserving computation realizes joint computation among multiple mu-tually distrustful participants while pre-serving the privacy of the computation,which has a wide range of applications in the data industry.In the context of cryp-tography,privac
At the time of writing(during the pan-demic),thinking about crowded spaces may make us uncomfortable,or melan-cholic at times.Some of us may even shy away from crowds by nature.But in their recent research paper in Nature,Ding Ma et al.show us that crowds

我们家有一块自留地,镶在一大片水田的边缘,形似一条幼嫩的舌头,浅浅地伸进宽阔的秋水河,啜饮清澈的河水,因而变得滋润肥沃.不过它的面积实在太小,仅有半余亩,且产权很不清晰,我的爷爷、舅爷爷、姨爹爹都以主人自居,都想按照自己的主意种点什么.可其他人也是这么想的,所以他们之间明争暗斗,互不相让.从血气方刚争到胡子花白,总算在酒桌上达成了盟约,那就是一人管一年,随你种茨菰、荸荠还是稻子,反正水田里能种的也只有这些.
段祺瑞生于1865年,与孙中山是同代人,长蒋介石一辈.1926年7月,国民革命军开始北伐,蒋介石是北伐军总司令.北伐军要打击、消灭的敌人是北洋军阀.段祺瑞是北洋军阀中最具有代表性的人物,也可以说,是继袁世凯之后的第一号人物.那么,段祺瑞应该是北伐军总司令蒋介石的头号敌人了?但事情又并非这么简单.段祺瑞与蒋介石有着师生之谊,段祺瑞能够善终,能够寿终正寝于沪滨,与蒋介石有着莫大关系.

N HK“大河剧”与织田信长相关者不少,观众每于织田军旗、帐幔或武士盔甲、背旗上赫然见“永乐通宝”钱纹.此其军徽也,信长乃日本战国间最重商之大名,特用以炫己富.人于货币,日常反应都是“钱”字,仅关贫富,其实那是货币较不重要的意义.rn货币,因人类社会趋于复杂而生.起初,生产惟自奉自给,从事何种劳动即因所获为食养,以外不能致.后当分工出现、交往扩大遂知交换,以我所有易以所无,己所不产亦因得之,然仅物物相换.
