| 1 | Fundamental principles and development of proximity-field nanopatterning toward advanced 3D nanofabrication显示文摘Three-dimensional(3D)nanoarchitectures have offered unprecedented material performances in diverse applications like energy storages,catalysts,electronic,mechanical,and photonic devices.These outstanding performances are attributed to unusual material properties at the nanoscale,enormous surface areas,a geometrical uniqueness,and comparable feature sizes with optical wavelengths.For the practical use of the unusual nanoscale properties,there have been developments for macroscale fabrications of the 3D nanoarchitectures with process areas over centimeter scales.Among the many fabrication methods for 3D structures at the nanoscale,proximity-field nanopatterning(PnP)is one of the promising techniques that generates 3D optical holographic images and transforms them into material structures through a lithographic process.Using conformal and transparent phase masks as a key factor,the PnP process has advantages in terms of stability,uniformity,and reproducibility for 3D nanostructures with periods from 300 nm to several micrometers.Other merits of realizing precise 3D features with sub-100 nm and rapid processes are attributed to the interference of coherent light diffracted by phase masks.In this review,to report the overall progress of PnP from 2003,we present a comprehensive understanding of PnP,including its brief history,the fundamental principles,symmetry control of 3D nanoarchitectures,material issues for the phase masks,and the process area expansion to the wafer-scale for the target applications.Finally,technical challenges and prospects are discussed for further development and practical applications of the PnP technique. | Sang-Hyeon Nam Gayea Hyun Donghwi Cho Seonggon Han Gwangmin Bae Haomin Chen Kisun Kim Youngjin Ham Junyong Park Seokwoo Jeon | 2021 | Nano Research2021，14，9： | 1 |
| 2 | Liquid-like adsorbent assembled by CNTs: Serving as renewable CO_(2) capture materials for indoor air显示文摘In this study,a CO_(2) capture material in the form of liquid-like adsorbents(LLAs) is developed to overcome the limitations of conventional types of adsorbents.The increase in indoor activities necessitates the capture of CO_(2) in enclosed indoor spaces.Indoor spaces require safe and stable materials for CO_(2) capture because humans are present in these spaces.Solid adsorbents are mainly used because liquid absorbents are unsuitable owing to noise and scattering problems.In LLA,the liquid absorbent assembled by carbon nanotubes(CNTs) is solidified and prevented from flowing and scattering indoor.LLAs present to maintain 95% of initial capacity after recycling 20 times,and have characteristics that can be regenerated in a low temperature heat source(80 to 120℃) and moisture resistance.This work not only provides indoor useable CO_(2) capture materials,but also offers a new prospect in the field of adsorbents. | Jae Won Lee Minjae Kim Han Sol Jung Ronghuan Xu Seonggon Kim Yong Tae Kang | 2021 | Journal of Energy Chemistry2021，30，12： | 1 |
