Use of the Erbium laser in treatment of peri-implantitis
Ho-yeol Jang, Jang-yeol Lee, Young-kyun Chung, Hwa-su Koong, Hyoun-chull Kim, Il-hae Park, Sang-chull Lee 대한치과이식임플란트학회 Journal of Dental Implant Research 11 Pages
대한치과이식임플란트학회 Journal of Dental Implant Research 2007, 제 26권 1호 8 49-59 (11 pages)
At the First European Workshop on Periodon tology, peri-implantitis was defined as an infla mmatory process affecting the tissues around an osseointegrated implant in function, resulting in loss of supporting bone. Peri-implant mucositis was defined as reversible inflammatory changes of the peri-implant soft tissues without any bone loss1). The infectious etiology of peri-implantitis is evident2). High levels of periodontal pathogens including Actinobacillus actinomycetemcomitans, Porphyromonas... -
A modified electrode by a facile green preparation of reduced graphene oxide utilizing olive leaves extract
Abeer Baioun, Hassan Kellawi, Ahamed Falah 한국탄소학회 Carbon Letters 8 Pages
한국탄소학회 Carbon Letters 2017, Vol.24 7 47-54 (8 pages)
Different phytochemicals obtained from various natural plant sources are used as reduction agents for preparing gold, copper, silver and platinum nanoparticles. In this work a green method of reducing graphene oxide (rGO) by an inexpensive, effective and scalable method using olive leaf aqueous extract as the reducing agent, was used to produce rGO. Both GO and rGO were prepared and investigated by ultraviolet and visible spectroscopy, Fourier-transform infrared, scanning electron microscopy,... -
Kinetic and multi-parameter isotherm studies of picric acid removal from aqueous solutions by carboxylated multi-walled carbon nanotubes in the presence and absence of ultrasound
Soheila Gholitabar, Hasan Tahermansouri 한국탄소학회 Carbon Letters 11 Pages
한국탄소학회 Carbon Letters 2017, Vol.22 2 14-24 (11 pages)
Carboxylated multi-wall carbon nanotubes (MWCNTs-COOH) have been used as efficient adsorbents for the removal of picric acid from aqueous solutions under stirring and ultrasound conditions. Batch experiments were conducted to study the influence of the different parameters such as pH, amount of adsorbents, contact time and concentration of picric acid on the adsorption process. The kinetic data were fitted with pseudo-first order, pseudo-secondorder, Elovich and intra-particle diffusion models.... -
Green synthesis of fluorescent carbon dots from carrot juice for in vitro cellular imaging
Yang Liu, Yanan Liu, Mira Park, Soo-Jin Park, Yifan Zhang, Md Rashedunnabi Akanda, Byung-Yong Park, Hak Yong Kim 한국탄소학회 Carbon Letters 7 Pages
한국탄소학회 Carbon Letters 2017, Vol.21 7 61-67 (7 pages)
We report the use of carrot, a new and inexpensive biomaterial source, for preparing high quality carbon dots (CDs) instead of semi-conductive quantum dots for bioimaging application. The as-derived CDs possessing down and up-conversion photoluminescence features were obtained from carrot juice by commonly used hydrothermal treatment. The corresponding physiochemical and optical properties were investigated by electron microscopy, fluorescent spectrometry, and other spectroscopic methods. The... -
Improving dispersion of multi-walled carbon nanotubes and graphene using a common non-covalent modifier
Youbin Kwon, Wonbo Shim, Seung-Yeol Jeon, Ji-Ho Youk, Woong-Ryeol Yu 한국탄소학회 Carbon Letters 9 Pages
한국탄소학회 Carbon Letters 2016, Vol.20 8 53-61 (9 pages)
The reportedly synergistic effects of carbon nanotubes (CNTs) and graphene hybrids have prompted strong demand for an efficient modifier to enhance their dispersion. Here, we investigated the ability of poly(acrylonitrile) (PAN) to overcome the van der Waals interaction of multi-walled CNTs (MWCNTs) and graphene by employing a simple wrapping process involving ultrasonication and subsequent centrifugation of PAN/MWCNT/graphene solutions. The physical wrapping of MWCNTs and graphene with PAN was... -
Activating needle coke to develop anode catalyst for direct methanol fuel cell
Young Hun Park, Ui-Su Im, Byung-Rok Lee, Dong-Hyun Peck, Sang-Kyung Kim, Young Woo Rhee, Doo-Hwan Jung 한국탄소학회 Carbon Letters 6 Pages
한국탄소학회 Carbon Letters 2016, Vol.20 7 47-52 (6 pages)
Physical and electrochemical qualities were analyzed after KOH activation of a direct methanol fuel cell using needle coke as anode supporter. The results of research on support loaded with platinum-ruthenium suggest that an activated KOH needle coke container has the lowest onset potential and the highest degree of catalyst activity among all commercial catalysts. Through an analysis of the CO stripping voltammetry, we found that KOH activated catalysis showed a 21% higher electrochemical... -
Effect of fiber-matrix adhesion on the fracture behavior of a carbon fiber reinforced thermoplastic-modified epoxy matrix
H.J. Carrillo-Escalante, A. ?lvarez-Castillo, A. Valadez-Gonz?lez, P. J. Herrera-Franco 한국탄소학회 Carbon Letters 10 Pages
한국탄소학회 Carbon Letters 2016, Vol.19 6 47-56 (10 pages)
In this study, the fracture behavior of a thermoplastic-modified epoxy resin reinforced with continuous carbon fibers for two levels of fiber-matrix adhesion was performed. A carbon fiber with commercial sizing was used and also treated with a known silane, (3-glycidoxy propyl trimethoxysilane) coupling agent. Toughness was determined using the double cantilever test, together with surface analysis after failure using scanning electron microscope. The presence of polysulfone particles improved... -
Carbon rich fly ash and their nanostructures
Numan Salah, Sami S. Habib, Zishan H. Khan, Ahmed Alshahrie, Adnan Memic, Attieh A. Al-ghamdi 한국탄소학회 Carbon Letters 9 Pages
한국탄소학회 Carbon Letters 2016, Vol.19 3 23-31 (9 pages)
Carbon rich fly ash was recently reported to have compositions that are ideal for use as a precursor and catalyst for carbon nanotube growth. This fly ash powder is mostly composed of pure carbon, predominantly present as sp2. In this work, the effect of sonication time on the morphology and structural properties of carbon rich fly ash particles is reported. The obtained results show that ultrasound treatment is an effective tool for producing ultrafine particles/fragments with higher porosity,...
