Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <italic>Supercapacitor:</italic> Mikio Fukuhara et al. (<ext-link ext-link-type="doi" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink">see pp. 477–480</ext-link>) discovered Ti–Ni–Si glassy alloy supercapacitors that can store electric charge on TiO₂ surfaces that contain many nanometer‐sized cavities. In contrast to the traditional electrochemical reactions, the supercapacitors do not require solutions with ions but directly charge/discharge electrons in wide temperature (∼193–453 K) and voltage (∼200 V) regions under DC and AC applications. The device consists in a distributed constant equivalent circuit of <italic>R</italic> and <italic>C</italic>. The cover picture shows de‐alloyed and anodic oxidized amorphous TiO₂ surface, where canyons of ca. 7 nm in size with higher work functions, <italic>Φ</italic>, of 5.53 eV can directly store electrons. Further gains could be attained with surface optimization.</p> <p> <boxed-text content-type="graphic" position="anchor" orientation="portrait"> <graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg271q916b" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /> </boxed-text> </p> </abstract>
