We report a facile and versatile strategy to prepare multi-dimensional nanocarbons hybridized with mesoporous SiO2. Carbon nanoplatelets (CNPs, two-dimensional structure of nanocarbons) were combined with carbon nanotubes (CNTs, onedimensional nanocarbons) to form multi-dimensional carbons (2D–1D, CNP–CNTs). The CNP–CNTs were synthesized by directly growing CNTs on CNPs. A simple solution-based process using TEOS (tetraethyl orthosilicate) resulted in coating or hybridizing CNP–CNTs with mesoporous silica to produce CNP–CNTs@SiO2. The nanocarbons’ surface area significantly increased as the amount of TEOS increased. Electrochemical characterizations of CNP–CNTs@SiO2 as supercapactior electrodes including cyclic voltammetry and galvanostatic charge–discharge in 3 M KOH (aq) reveal excellent-specific capacitance of 23.84 mF cm−2 at 20 mV s−1, stable charge–discharge operation, and low internal resistance. Our work demonstrates mesoporous SiO2 on nanocarbons have great potential in electrochemical energy storage.
Benign fibrous histiocytomas that is also known asDermatofibroma,Fibrous dermatofibroma, andFibrous histiocytoma are benign skin growths. They are composed of disordered collagen laid down by fibroblasts. In rare cases, basal cell carcinoma may develop in that. Benign fibrous histiocytomas of bone are unusual neoplasms that often are confused with metaphyseal fibrous defects. It is an uncommon neoplasm of the Head and Neck region. It is a rare and usually painless oral tumor. Several cases were reported in mandible, but few in maxilla, especially in maxillary gingiva. We are reporting a case of Maxillay gingival.
Plasma cell myeloma is malignant disease of plasma cell in the bone marrow. Myeloma accounts for about 1% of all cancers. The solitary plasma cellmyeloma is rare tumors and account for less than 10% of plasma cell neoplasm. It is often progress to multiple myeloma at 30~40% despite successful local treatment with surgery and radiation therapy. We are reporting a case of solitary plasma cell myeloma on anterior Maxillary region that developed after kidney transplantation and immunosuppressive therapy.
Kwanganbyeo is a japonica rice variety developed from the cross between Namyang 7 and SR14779-HB234-31, anelite line derived from the cross between Cheonmabyeo and Aichi 37 at the National Crop Experiment Station, RDA, and washi-tecture and light-dark gre
