This paper will provide a view of the current state of technological progress in reliability of electronic package in Japan, and will discus…
Thin ZnO nanostructured films were produced by pulsed laser deposition (PLD) for surface enhanced Raman spectroscopy (SERS) studies. The experimental conditions used for preparation of the samples were chosen to obtain different types of ZnO nanostructures. The Raman spectra of rhodamine 6G (R6G) were measured at an e…
Nano-TiO 2 particles with a range of crystallite sizes were synthesized by a conventional sol-gel method, and then used as nanoparticle substrates in the synthesis of LLDPE/TiO 2 nanocomposites via in situ polymerization of ethylene/1-hexene with zirconocene/MMAO catalyst. It was found that the size of the nano-TiO 2…
Same type fabric and same cutting plan can be cut in different methods by using computer aided fabric cutting systems. This is possible with changing the parameters inside the program which is operating the cutter. In this research; the effects of cutting parameters on the cutting quality and the cutting duration were…
The effects of Al 2 O 3 on the crystallization behavior of glass compositions in the Na 2 O-CaO-SiO 2 system were investigated by differential thermal analysis (DTA), X-ray diffraction (XRD), and scanning electron microscopy (SEM). The effect of Al 2 O 3 content on the mechanical properties, density, phase formation,…
This paper reported a simple deposition-precipitation method, introducing the metal (Ni, Ag and Sn) and Na 2 S• 5H 2 O to preparedispersion metal sulfide nanoparticles on the surface of the Multi-walled carbon nanotube for synthesis of CNT-M x S y (NiS 2 , Ag 2 S, SnS) composite photocatalysts.The characterization of…
The resistance of asphaltic concrete to cracking is dependent upon its tensile strength and flexibility characteristics. Also the low tensile strength has recognized as a major contributor to other performance problems.The fatigue life of mixtures decreases exponentially with decreasing of tensile strength. This trend…
The temperature-rasing sintering method was used in this study to fabricate the aggregates of uniform pore size and distribution containing reject ash occurred in the thermal power plant.The spheric green aggregates made of reject ash were put into the box furnace of 800~1000 o C, heated with a heating rate of 5~15 o…
우리나라에는 약 6개소의 사문석광산이 존재하였으며, 그 중에 최근까지 채굴되었던 충남지역의 비봉광산에 대하여 구성광물의 산출상태, 특성 및 성인을 검토하였다. X-선회절분석, X-선형광분석, 주사현미분석, 전자현미분석, 적외선분광분석, 편광현미경관찰 등을 통하여 사문석의 광물학적 특성을 조사하였다. 비봉광산의 사문암체는 선캠브리아기의 변성퇴적암을 관입한 형태로 소규모로 분포하여 나타나며, 사문석, 포스터라이트, 휘석, 투각섬석, 자철석, 녹니석, 운모, 활석, 돌로마이트 등의 다양한 광물들이 산출되었다. 사문암체의 광물조합은 크게 A) 사문석-포스터라이트, B) 사…
Structure and superficial properties of tectosilicates found in soils with potential to retain uranium are studied in this work. These tectosilicates are largely available as natural minerals in the soil and are composed mainly by anorthite (CaAl 2 Si 2 O 8 ), albite (NaAlSi 3 O 8 ) and orthoclase (KAlSi 3 O 8 ), in w…
A novel, sensitive and convenient method for the determination of tizanidine hydrochloride (TZD) based on the fluorescence quenching of thioglycolic acid-capped CdS quantum dots (TGA-CdS QDs) is proposed. Luminescent CdS semiconductor quantum dots modified by thioglycolic acid were synthesized from cadmium nitrate and…
IPMC was considered as a polyelectrolyte membrane sandwiched between two flat electrodes in most of its theoretical models. However, structural idealization (ignorance of the interface) may lead to problematic predictions; therefore a proper model to characterize IPMC structures is expected for a more sophisticated el…
In this study, antimicrobial and dyeing properties of CI Basic Green 4 dye and dyed acrylic fabrics have been studied against the common pathogens Escherichia coli, Bacillus subtilis, Staphylococcus aureus, and Pseudomonas aeruginosa.CI Basic green 4 dye was effective against selected test bacteria E. coli, B. subtili…
Optical losses measurements were performed at 1550 nm on both porous silicon (PSi) and oxidised PSi (OPSi) planar waveguides as a function of interface roughness. The PSi waveguides were produced at different anodisation temperatures to reduce the interface roughness. The authors noticed a decrease in optical losses w…
YPO4:Eu3+ hollow microspheres were synthesised by using the spheres of PS/Y(OH)CO3:Eu3+ as a precursor. The whole process mainly consists of the hydrothermal reaction and calcination. The YPO4:Eu3+ hollow spheres were characterised by X-ray diffraction, scanning electron microscopy, transmission electron microscopy an…
Artificial muscles based on dielectric elastomers show enormous promise for a wide range of applications and are slowly moving from the lab to industry. One problem for industrial uptake is the expensive, rigid, heavy and bulky high voltage driver, sensor and control circuitry that artificial muscle devices currently…
