Competition of the roles of π-conjugated domain between emission center and quenching origin in the photoluminescence of carbon dots depending on the interparticle separation
Autor: Do Hyun Kim, Hyo Jeong Yoo, Byeong Eun Kwak
Publikováno v: Carbon. 183:560-570
The π-conjugated domain, which is one of frequently-suggested fluorescence origin of carbon dots (CDs), can also act as fluorescence quenching origin in aggregated state. This dual role of the π-conjugated domain in CDs offers a challenge to predic

Large-Scale Centrifugal Multispinning Production of Polymer Micro- and Nanofibers for Mask Filter Application with a Potential of Cospinning Mixed Multicomponent Fibers
Autor: Hyo Jeong Yoo, Do Hyun Kim, Eungjun Lee, Byeong Eun Kwak
Publikováno v: ACS Macro Letters
Recently, the polymer nanofiber web is in high demand as a strong barrier against harmful particles due to its high capture efficiency and strong droplet-blocking ability. As an advanced spinning technique, the centrifugal multispinning system was de

Self-Quenching Origin of Carbon Dots and the Guideline for Their Solid-State Luminescence
Autor: Do Hyun Kim, Byeong Eun Kwak, Hyo Jeong Yoo
Publikováno v: The Journal of Physical Chemistry C. 123:27124-27131
Realization of luminescent carbon dots (CDs) in the solid state has been a critical issue for their applications in various fields, such as optoelectronic devices and inkjet printing. However, lumi...

Interparticle distance as a key factor for controlling the dual-emission properties of carbon dots
Autor: Do Hyun Kim, Byeong Eun Kwak, Hyo Jeong Yoo
Publikováno v: Physical chemistry chemical physics : PCCP. 22(36)
Due to their distinct and useful features, multi-color-emissive carbon dots (CDs) have gained much attention, however, their lack of red emission has so far limited their practical use for various applications, thus understanding of their emission or

Autor: Bong Gill Choi, Byeong Eun Kwak, Jo Hee Yoon, Jungwon Kim, Jae Goo Yeo, Jae-Min Jeong, Geun Young Lee, Se Bin Jin, Do Hyun Kim, Mobina Irshad, Donghyuk Seo, Seongwoo Lee
Publikováno v: Catalysts; Volume 9; Issue 1; Pages: 25
Catalysts, Vol 9, Iss 1, p 25 (2018)
We report on the high-throughput production of heterogeneous catalysts of RuO2-deposited graphene using a hydrodynamic process for selective alcohol oxidation. The fluid mechanics of a hydrodynamic process based on a Taylor–Couette flow provide a h
