This study reports on Co/ $Co_2$ MnSn two-phase magnets. The Co/ $Co_2$ MnSn two-phase magnet has Co precipitates in a $Co_2MnSn$ Heusler alloy matrix, in which the two phases are exchange-coupled at the phase boundary. The as-casted Co/ $Co_2$ MnSn system, which has Co-Mn solid solution precipitates in a $Co_2$ MnSn…
In this paper, a fast responded ferroelectric liquid crystal (FLC) driven with low voltage is achieved. The switching time and contrast ratio of two different FLC materials are investigated with the temperature range from room temperature to 80°C. The switching time of 50?s and contrast of 300:1 are obtained with FLC5…
Here, we report on the synthesis of PEG-Mn 3 O 4 nanocomposite (NP’s) via a hydrothermal route by using Mn(acac) 2 , ethanol, NH 3 and PEG-400. The crystalline phase was identified as Mn 3 O 4 . The crystallite size of the PEG-Mn 3 O 4 nanocomposite was calculated as 12±5 nm from X-ray line profile fitting and the ave…
Novel copolymers of trisubstituted ethylene monomers, ring-substituted 2-phenyl-1,1-dicyanoethylenes, RC6H2CH=C(CN)2 (where R is 2,4-(CH3O)2-3-CH3, 2,3,4-(CH3O)3, 2,4,5-(CH3O)3, 2,4,6-(CH3O)3, 3,4,5-(CH3O)3, 6-Br-3,4-(CH3O)2), 2,3,5-Cl3, 2,3,6-Cl3 and 4-fluorostyrene were prepared at equimolar monomer feed composition…
Wirkstofftragende Dendrimere ermöglichten in Kombination mit massenspektrometrischer Analyse, Wirkstoffziele in vitro und in lebenden Zellen zu identifizieren. Dabei wird das wirkstofftragende Nanopolymer mit Zellen inkubiert, um einen effizienten Transport in die Zellen sicherzustellen (siehe Bild), und die Zellen we…

Abstract Ab initio calculations are performed to study the electronic and magnetic properties of the cubic inverse perovskite RRh3C (R = rare earth) compounds. In this work, we used the accurate augmented plane‐wave plus local orbital method to find the equilibrium structural parameters and to determine the magnetic s…
In this paper we discuss the fabrication of high-density InAs quantum dots (QDs) on GaAs (1 0 0) substrates by molecular beam epitaxy, via antimony surfactant-mediated growth. The structural and optical properties of the QDs were studied as a function of the amount of antimony irradiation. It was found that with appro…
Several types of phosphorus-containing dendrimers bearing fluorescent derivatives in their structures are reviewed. The fluorescent groups can be used as terminal groups, or at the core, or linked to the core or to the branches of the dendritic structure. The types of fluorescent entities used are pyrene, dansyl, phth…
Phenytoin, an antiepileptic drug is used in managing seizures. Phenytoin-associated oxidative stress causes cellular damage by the generation of free radicals. Vitamin C, a standard antioxidant and Calotropisprocera are believed to scavenge oxygen free radicals. The effect of C. procera extract on haematological and b…
본 연구에서는 원유, 휘발유, 등유, 경유를 분해하면서 생물계면활성제를 생산하는 균주인 B. subtilis JK-1을 선별하여 생물계면활성제 생산에 관한 연구를 수행하였다. 생물계면활성제생산을 위한 최적 배지를 결정하기 위해 다양한 탄소원과 질소원, 무기염류를 조사하였다. B. subtilis JK-1은 탄소원인 1.0%(w/v) soluble starch와 질소원인 0.5% (w/v) skim milk를 포함한 배지에서 96 시간 동안 배양한 결과 가장 많은 생물계면활성제를 생산하였으며, 이 때 탄소원과 질소원의 비율은 2.0이었다. 그리고 0.1% (w/v)의…
This investigates the type of pants preferred by Korean men in their 20s through a subjective wear test. Six types of men's pants were developed as experimental garments. The male subjects were university students between the ages of 20 and 24. Subjective wear sensations of the experimental pants were rated using seve…
Abstract Summary: To safeguard runaway reactions in industrial scale, qualified methods have to be used. While mechanical safety devices are usually installed, their design may be problematic as the runaway kinetics must be known. This may not be the case for many processes due to the required flexibility and possible…
We found that La${}_{5}$Mo${}_{4}$O${}_{16}$ with Mo${}^{4+}$ and Mo${}^{5+}$ ions ($S=1$ and $S=1/2$ spins) on a quasisquare lattice exhibits a distinct magnetoresistance for the current perpendicular to the square-lattice layers below the antiferromagnetic ordering temperature ${T}_{\mathrm{AF}}=190$ K. This magneto…

In this research, mechanical and microstructure properties of cold pressing (CP) and extrusion (EXTR) specimens produced via powder metallurgy were investigated and compared. For this comparison, EXTR specimens were hot extruded at 565°C with an extrusion ratio of 4:1. Likewise, CP specimens were compacted under a pre…
Pineapple (Ananas comosus (L.) Merrill.) contains many nutrients and enzyme. It is mostly grown on strongly acid soils in Taiwan. In strongly acid soils, aluminum (Al) is biotoxic and may inhibit growth of crops. This study is to evaluate the effects of different Al concentration in hydroponic solutions on the nutrien…
Abstract The formation of a nanostructured interpenetrating polymer network (IPN) via electropolymerization is described. The electro‐copolymerization of alternate layer‐by‐layer (LbL) self‐assembled polyelectrolytes with thiophene and carbazole pendant monomers was demonstrated facilitating IPN formation of π‐conjuga…
Abstract GaN‐based light‐emitting diodes (LEDs) grown on c‐plane vicinal sapphire substrates are fabricated and characterized. All the electrical characteristics demonstrate that the LED with a 0.2° tilt sapphire substrate exhibits the lowest defect density while that with a 1.0° tilt sapphire exhibits the highest one…
