Potassium ion batteries (PIBs) are gaining traction as an alternative scalable energy storage system due to a high abundance of potassium resources(1.5 wt% in the Earth\'s crust),fast ion transport kinetics of K+ in electrolyte and low standard reduction potential of potassium (-2.93 V vs.standard elec-trode potential (E0)) [1-4].

Digital signatures and key exchange pro-tocols are the two most important pub-lic key cryptographic primitives used in the electronic transmission of data.The goal of key exchange is to preserve the secrecy of the communication,while the goal of digital s

记得是上世纪八十年代,父亲的书房里曾经悬过一幅字,是他一生的老师、曾经的系主任朱东润先生的手书.那是苏轼的《赠孙莘老七绝》之一:rn嗟予与子久离群,耳冷心灰百不闻.rn若对青山谈世事,当须举白便浮君.rn朱先生写好这幅字后,就放进一个牛皮纸大信封,送到了当时我家住的复旦大学第四宿舍门房.那幅字写得好,父亲觉得一“那气势说高山苍松,说虬龙出海,都既无不可又不够贴切.”(潘旭澜《若对青山谈世事——怀念朱东润先生》)朱先生的字上没有写年月,但父亲的文章中说是1987年,因为父亲记忆力极佳,所以不会错.也许是想起

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.
