Journal ArticleDOI
Gram‐Scale Synthesis of Cu2O Nanocubes and Subsequent Oxidation to CuO Hollow Nanostructures for Lithium‐Ion Battery Anode Materials
TL;DR: Nano RD program as discussed by the authors was proposed by the Korea Science and Engineering Foundation (KOSEF) and the Korean Government (MOST) for the development of artificial neural networks.
Journal ArticleDOI
Self-Powered Cardiac Pacemaker Enabled by Flexible Single Crystalline PMN-PT Piezoelectric Energy Harvester
Geon-Tae Hwang,Hyewon Park,Jeong Ho Lee,SeKwon Oh,Kwi-Il Park,Myunghwan Byun,Hyelim Park,Ahn Gun,Chang Kyu Jeong,Kwangsoo No,Hyuk-Sang Kwon,Sang Goo Lee,Boyoung Joung,Keon Jae Lee +13 more
TL;DR: A flexible single-crystalline PMN-PT piezoelectric energy harvester is demonstrated to achieve a self-powered artificial cardiac pacemaker that meets the standard for charging commercial batteries but also for stimulating the heart without an external power source.
Journal ArticleDOI

Geon-Tae Hwang,Young-Soo Kim,Jeong Ho Lee,SeKwon Oh,Chang Kyu Jeong,Dae Yong Park,Jungho Ryu,Hyuk-Sang Kwon,Sang Goo Lee,Boyoung Joung,Daesoo Kim,Keon Jae Lee +11 more
TL;DR: In this paper, a flexible piezoelectric energy harvester was used to enable self-powered DBS in mice, which achieved an extremely high current reaching 0.57 mA, which satisfies the high threshold current for real-time DBS of the motor cortex.
Journal ArticleDOI
Syntheses and Characterization of Wurtzite CoO, Rocksalt CoO, and Spinel Co3O4 Nanocrystals: Their Interconversion and Tuning of Phase and Morphology
Ki Min Nam,Jae Ha Shim,Dongwook Han,Hyuk-Sang Kwon,Yong-Mook Kang,Yan Li,Hyunjoon Song,Won Seok Seo,Joon T. Park +8 more
TL;DR: In this article, a single molecular precursor Co(acacac)3 (acac: acetylacetonate) has been selectively prepared through thermodynamically and kinetically controlled reactions of a one molecular precursor.
Journal ArticleDOI
Structural enhancement of Na3V2(PO4)(3)/C composite cathode materials by pillar ion doping for high power and long cycle life sodium-ion batteries
