Journal ArticleDOI
2-dimensional analytic approach for anion differentiation with chromofluorogenic receptors.
T. Daniel Thangadurai,N. Jiten Singh,In-Chul Hwang,Jung Woo Lee,R. Prakash Chandran,Kwang S. Kim +5 more
TL;DR: By linking the urea moiety at the 1,8 positions of the carbazole fragment, the host systems 1, 2, and 3 are synthesized having both chromogenic and fluorogenic signaling subunits, which enables us to differentiate the given set of anions.
Journal ArticleDOI
Accelerated Bone Regeneration by Two-Photon Photoactivated Carbon Nitride Nanosheets.
Jitendra N. Tiwari,Young Kyo Seo,Taeseung Yoon,Wang-Geun Lee,Woo Jong Cho,Muhammad Yousuf,Ahmad M. Harzandi,Du-Seok Kang,Kwang-Youn Kim,Pann-Ghill Suh,Kwang S. Kim +10 more
TL;DR: Red-light absorbing carbon nitride sheets lead to remarkable proliferation and osteogenic differentiation by runt-related transcription factor 2 (Runx2) activation, a key transcription factor associated with osteoblast differentiation in human bone marrow-derived mesenchymal stem cells.
Journal ArticleDOI
Fluorescent imidazolium-based cyclophane for detection of guanosine-5'-triphosphate and I(-) in aqueous solution of physiological pH.
TL;DR: A new water-soluble and fluorescent imidazolium-anthracene cyclophane effectively recognizes the biologically important GTP and I(-) over other anions in a 100% aqueous solution of physiological pH 7.4.
Journal ArticleDOI
Quantum size effects in the volume plasmon excitation of bismuth nanoparticles investigated by electron energy loss spectroscopy
TL;DR: In this paper, the volume plasmon energy and its peak width increase with decreasing nanoparticle diameter, due to the quantum size effect, confirming the semimetal to semiconductor transition in Bi nanoparticles.
Journal ArticleDOI
N-Protonation vs O-Protonation in Strained Amides: Ab Initio Study
Seung Joo Cho,Chunzhi Cui,Jin Yong Lee,Jong Keun Park,Seung Bum Suh,Jaiwook Park,Byeang Hyean Kim,Kwang S. Kim +7 more
TL;DR: In this article, the electron correlation effect was used to determine the protonation sites of strained amides, since it contributes to stabilize N-protonation somewhat more than O-proptonation.
