Relationships between dielectric properties and characteristics of impregnated and activated samples of potassium carbonate- and sodium hydroxide-modified palm kernel shell for microwave-assisted activation
Norulaina Alias, Muhammad Abbas Ahmad Zaini, Mohd Johari Kamaruddin 한국탄소학회 Carbon Letters 11 Pages
한국탄소학회 Carbon Letters 2017, Vol.24 9 62-72 (11 pages)
a mass ratio of 1.5) exhibited a high loss tangent (tan δ) indicating the effectiveness of these materials to be heated by microwaves. K2CO3 and NaOH can act as a microwave absorber to enhance the efficiency of microwave heating for low loss PKSs. Materials with a high moisture content exhibit a high loss tangent but low penetration depth. The interplay of multiple operating frequencies is suggested to promote better microwave heating by considering the changes in the materials characteristics. -

에폭시 수지 DGEBA/MDA/GN계의 트링 열화에 미치는 전압과 온도의 영향에 대한 고찰을 통하여 고분자 절연재료의 절연파괴 거동을 연구하였다. 전압 인가시간에 따라 트리의 성장속도은 역S자의 형태로 나타났다. 인가전압과 온도가 증가함에 따라 트리의 성장속도는 증가하였으며 트리형상의 복잡함, 즉 국부적인 트링열화의 정도는 인가전압이 감소하거나 온도가 증가한 경우에 높게 나타났다. 절연파괴 강도는 유리 전이온도 이상에서 급격히 감소하였다. -

Background : The one-leg standing (OLS) test is a method of evaluating trunk stability. The transverse abdominis (TrA) is an important muscle that contributes to trunk stability during functional movement through abdominal draw-in maneuver (ADIM). The gluteus medius (Gmed) is also important for functional movement and for stability of the hip joints in the muscles that prevent lateral deviation of the trunk in OLS. During ADIM, the Gmed, TrA and internal oblique (IO) muscles are activated. It... -

Mechanical and electrical properties of cement paste incorporated with pitch-based carbon fiber
Inkyu Rhee, Jin Hee Kim, Sang Hee Park, Sungho Lee, Bong Ryeul Ryu, Yoong Ahm Kim 한국탄소학회 Carbon Letters 8 Pages
한국탄소학회 Carbon Letters 2017, Vol.23 4 22-29 (8 pages)
The compressive strength and electrical resistance of pitch-based carbon fiber (CF) in cementitious materials are explored to determine the feasibility of its use as a functional material in construction. The most widely used CFs are manufactured from polyacrylonitrile (PAN-based CF). Alternatively, short CFs are obtained in an economical way using pitch as a precursor in a melt-blown process (pitch-based CF), which is cheaper and more eco-friendly method because this pitch-based CF is basically... -

morphological characteristics, particle sizes and surface area of the prepared catalyst was investigated. The prepared catalysts were characterized by several analytical methods: high resolution scanning electron microscopy (HRSEM), energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET), and X-ray photoelectron spectroscopy (XPS). The XRD patterns showed that the supported TiO₂ nanocrystals are typically anatase, polycrystalline and body-centered tetragonal... -
A review: role of interfacial adhesion between carbon blacks and elastomeric materials
Min-Joo Kang, Young-Jung Heo, Fan-Long Jin, Soo-Jin Park 한국탄소학회 Carbon Letters 10 Pages
한국탄소학회 Carbon Letters 2016, Vol.18 1 1-10 (10 pages)
Carbon blacks (CBs) have been widely used as reinforcing materials in advanced rubber composites. The mechanical properties of CB-reinforced rubber composites are mostly controlled by the extent of interfacial adhesion between the CBs and the rubber. Surface treatments are generally performed on CBs to introduce chemical functional groups on its surface. In this study, we review the effects of various surface treatment methods for CBs. In addition, the preparation and properties of CB-reinforced... -
Microwave-assisted pretreatment technologies for the conversion of lignocellulosic biomass to sugars and ethanol: a review
Pradeep Puligundla, Sang-Eun Oh, Chulkyoon Mok 한국탄소학회 Carbon Letters 10 Pages
한국탄소학회 Carbon Letters 2016, Vol.17 No.1 1 1-10 (10 pages)
Lignocellulosic biomass conversion to biofuels such as ethanol and other value-added bio-products including activated carbons has attracted much attention. The development of an efficient, cost-effective, and eco-friendly pretreatment process is a major challenge in lignocellulosic biomass to biofuel conversion. Although several modern pretreatment technologies have been introduced, few promising technologies have been reported. Microwave irradiation or microwave-assisted methods (physical and... -
Characterization and influence of shear flow on the surface resistivity and mixing condition on the dispersion quality of multi-walled carbon nanotube/polycarbonate nanocomposites
Young Sil Lee, Kwan Han Yoon 한국탄소학회 Carbon Letters 7 Pages
한국탄소학회 Carbon Letters 2015, Vol.16 No.2 3 86-92 (7 pages)
Multi-walled carbon nanotube (MWCNT)/polycarbonate (PC) nanocomposite was prepared by direct melt mixing to investigate the effect of the shear rate on the surface resistivity of the nanocomposites. In this study, an experiment was carried out to observe the shear induced orientation of the MWCNT in the polymer matrix using a very simple melt flow indexer with various loads. The compression-molded, should be eliminated. MWCNT/PC nanocomposite sample exhibited lower percolation thresholds (at 0.8... -
Preparation and characterization of carbon fiber-reinforced thermosetting composites: a review
Fan-Long Jin, Soo-Jin Park 한국탄소학회 Carbon Letters 11 Pages
한국탄소학회 Carbon Letters 2015, Vol.16 No.2 1 67-77 (11 pages)
mainly by the quality of interfacial adhesion between the CFs and the polymer matrix. Surface treatments of CFs are generally carried out to introduce chemical functional groups on the fiber surfaces, which provide the ability to control the surface characteristics of CFs. In this study, we review recent experimental studies concerning various surface treatment methods for CFs. In addition, direct examples of the preparation and properties of CF-reinforced thermosetting composites are discussed.
