Geometric and electronic structures of monolayer hexagonal boron nitride with multi-vacancy
Nano Convergence - Tập 4 - Trang 1-8 - 2017
Do-Hyun Kim, Hag-Soo Kim, Min Woo Song, Seunghyun Lee, Sang Yun Lee
Hexagonal boron nitride (h-BN) is an electrical insulator with a large band gap of 5 eV and a good thermal conductor of which melting point reaches about 3000 °C. Due to these properties, much attention was given to the thermal stability rather than the electrical properties of h-BN experimentally and theoretically. In this study, we report calculations that the electronic structure of monolayer h...... hiện toàn bộ
Biomimetic and bioorthogonal nanozymes for biomedical applications
Nano Convergence -
Changjoon Keum, Cristina‐Maria Hirschbiegel, Soham Chakraborty, Soyeong Jin, Youngdo Jeong, Vincent M. Rotello
AbstractNanozymes mimic the function of enzymes, which drive essential intracellular chemical reactions that govern biological processes. They efficiently generate or degrade specific biomolecules that can initiate or inhibit biological processes, regulating cellular behaviors. Two approaches for utilizing nanozymes in intracellular chemistry have been reported. Bi...... hiện toàn bộ

Magnetic and near-infrared derived heating characteristics of dimercaptosuccinic acid coated uniform Fe@Fe3O4 core–shell nanoparticles
Nano Convergence - Tập 7 - Trang 1-9 - 2020
Changhyuk Koo, Hwichan Hong, Pyung Won Im, Hoonsub Kim, Chaedong Lee, Xuanzhen Jin, Bingyi Yan, Wooseung Lee, Hyung-Jun Im, Sun Ha Paek, Yuanzhe Piao
Among the number of hyperthermia materials, magnetic nanoparticles have received much attention. In this work, we studied the heating characteristics of uniform Fe@Fe3O4 core–shell nanoparticle under near-infrared laser irradiation and external AC magnetic field applying. The Fe@Fe3O4 core–shell nanoparticles were prepared by thermal decomposition of iron pentacarbonyl and followed by controlled o...... hiện toàn bộ
Recent advances in carbon quantum dots for virus detection, as well as inhibition and treatment of viral infection
Nano Convergence - Tập 9 - Trang 1-31 - 2022
Yuxiang Xue, Chenchen Liu, Gavin Andrews, Jinyan Wang, Yi Ge
In the last decade, carbon quantum dots (CQDs), as a novel class of carbon-based nanomaterials, have received increasing attention due to their distinct properties. CQDs are ultimately small nanoparticles with an average size below 10 nm, possessing high water solubility, alluring photoluminescence, photostability, excellent biocompatibility, low/none toxicity, environmental friendliness, and high...... hiện toàn bộ
Ultrasensitive and real-time optical detection of cellular oxidative stress using graphene-covered tunable plasmonic interfaces
Nano Convergence - Tập 9 - Trang 1-12 - 2022
Hakchun Kim, Hyun Ji An, Junhee Park, Yohan Lee, Min Seob Kim, Seungki Lee, Nam Dong Kim, Jihwan Song, Inhee Choi
Reactive oxygen species (ROS) regulate various physiological and pathological conditions in cells by interacting with signaling molecules and inducing oxidative stress. Therefore, sensitive monitoring of ROS levels in living cells is important to track cellular state and study the complex role of ROS in the development of various pathologies. Herein, we present an optically tunable plasmonic inter...... hiện toàn bộ
Progress and outlook of Sn–Pb mixed perovskite solar cells
Nano Convergence -
Hyemin Lee, Seok Beom Kang, Sangwook Lee, Kai Zhu, Dong Hoe Kim
AbstractOrganic–inorganic hybrid perovskites have revolutionized solar cell research owing to their excellent material properties. Most previous research has been done on Pb-based perovskites. Recently, efforts to discover a Pb-free or Pb-less perovskite material with an ideal bandgap ranging 1.1–1.3 eV have led researchers to investigate Sn–Pb mixed perovskites. S...... hiện toàn bộ
MHD boundary layer radiative, heat generating and chemical reacting flow past a wedge moving in a nanofluid
Nano Convergence - Tập 1 - Trang 1-13 - 2014
Md Shakhaoath Khan, Ifsana Karim, Md Sirajul Islam, Mohammad Wahiduzzaman
The present study analyzed numerically magneto-hydrodynamics (MHD) laminar boundary layer flow past a wedge with the influence of thermal radiation, heat generation and chemical reaction. This model used for the momentum, temperature and concentration fields. The principal governing equations is based on the velocity u w (x) in a nanofluid and with a parallel fre...... hiện toàn bộ
Applications of remote epitaxy and van der Waals epitaxy
Nano Convergence - Tập 10 - Trang 1-17 - 2023
Ilpyo Roh, Seok Hyeon Goh, Yuan Meng, Justin S. Kim, Sangmoon Han, Zhihao Xu, Han Eol Lee, Yeongin Kim, Sang-Hoon Bae
Epitaxy technology produces high-quality material building blocks that underpin various fields of applications. However, fundamental limitations exist for conventional epitaxy, such as the lattice matching constraints that have greatly narrowed down the choices of available epitaxial material combinations. Recent emerging epitaxy techniques such as remote and van der Waals epitaxy have shown excit...... hiện toàn bộ
Universal behaviour of high-Q Fano resonances in metamaterials: terahertz to near-infrared regime
Nano Convergence - Tập 5 - Trang 1-7 - 2018
Wen Xiang Lim, Ranjan Singh
The observation of Fano resonance phenomena is universal across several branches of physics. Photonics is one of the most important areas of physics that mainly deals with the control of light propagation and localization through its interaction with natural and artificially engineered media. In an era of miniaturization, manipulation of light at micro-nanoscales has assumed unprecedented signific...... hiện toàn bộ
