    Graphene-Like ZnO: A Mini Review
    (Basel : MDPI, 2016) Ta, Huy Q.; Zhao, Liang; Pohl, Darius; Pang, Jinbo; Trzebicka, Barbara; Rellinghaus, Bernd; Pribat, Didier; Gemming, Thomas; Liu, Zhongfan; Bachmatiuk, Alicja; Rümmeli, Mark H.
    The isolation of a single layer of graphite, known today as graphene, not only demonstrated amazing new properties but also paved the way for a new class of materials often referred to as two-dimensional (2D) materials. Beyond graphene, other 2D materials include h-BN, transition metal dichalcogenides (TMDs), silicene, and germanene, to name a few. All tend to have exciting physical and chemical properties which appear due to dimensionality effects and modulation of their band structure. A more recent member of the 2D family is graphene-like zinc oxide (g-ZnO) which also holds great promise as a future functional material. This review examines current progress in the synthesis and characterization of g-ZnO. In addition, an overview of works dealing with the properties of g-ZnO both in its pristine form and modified forms (e.g., nano-ribbon, doped material, etc.) is presented. Finally, discussions/studies on the potential applications of g-ZnO are reviewed and discussed.

    Applications of Carbon Nanotubes in the Internet of Things Era
    (Berlin ; Heidelberg [u.a.] : Springer, 2021) Pang, Jinbo; Bachmatiuk, Alicja; Yang, Feng; Liu, Hong; Zhou, Weijia; Rümmeli, Mark H.; Cuniberti, Gianaurelio
    The post-Moore's era has boosted the progress in carbon nanotube-based transistors. Indeed, the 5G communication and cloud computing stimulate the research in applications of carbon nanotubes in electronic devices. In this perspective, we deliver the readers with the latest trends in carbon nanotube research, including high-frequency transistors, biomedical sensors and actuators, brain-machine interfaces, and flexible logic devices and energy storages. Future opportunities are given for calling on scientists and engineers into the emerging topics.

    Single “Swiss-roll” microelectrode elucidates the critical role of iron substitution in conversion-type oxides
    (Washington, DC [u.a.] : Assoc., 2022) Liu, Lixiang; Huang, Shaozhuan; Shi, Wujun; Sun, Xiaolei; Pang, Jinbo; Lu, Qiongqiong; Yang, Ye; Xi, Lixia; Deng, Liang; Oswald, Steffen; Yin, Yin; Liu, Lifeng; Ma, Libo; Schmidt, Oliver G.; Shi, Yumeng; Zhang, Lin
    Advancing the lithium-ion battery technology requires the understanding of electrochemical processes in electrode materials with high resolution, accuracy, and sensitivity. However, most techniques today are limited by their inability to separate the complex signals from slurry-coated composite electrodes. Here, we use a three-dimensional “Swiss-roll” microtubular electrode that is incorporated into a micrometer-sized lithium battery. This on-chip platform combines various in situ characterization techniques and precisely probes the intrinsic electrochemical properties of each active material due to the removal of unnecessary binders and additives. As an example, it helps elucidate the critical role of Fe substitution in a conversion-type NiO electrode by monitoring the evolution of Fe2O3 and solid electrolyte interphase layer. The markedly enhanced electrode performances are therefore explained. Our approach exposes a hitherto unexplored route to tracking the phase, morphology, and electrochemical evolution of electrodes in real time, allowing us to reveal information that is not accessible with bulk-level characterization techniques.
