Nanoscale ionic materials（NIMS） based on carbon black（CB） were prepared through a facile method. Firstly, CB was oxidized in the mixture of nitric acid and sulfuric acid, resulting in a large amounts of -COOH on surface of CB. Then oxidized CB was grafted by polyetheramine through neutralization reaction between -COOH of CB and -NH_2- of polyetheramine, and CB derivatives were obtained. This surface- functionalized CB can behave as liquid at ambient temperature in the absence of solvent by carefully varying the components. FTIR and thermaogravimelric analysis confirmed that the successively grafting of polyetheramine. TEM revealed the monodisperse core-shell structure of CB derivatives particles. The viscoelasticity of CB derivatives were closely related to the molecular weight and loading of polyetheramine. The unique core- shell and ionic structure and flowability of these CB derivatives could guide our future work on obtaining NIMs with tunable and controllable properties and broaden its commercial applications.

In recent years, a large number of structures that were built during the period of high economic growth in Japan is beginning to show signs of aging. For example, the structural performance of steel structures has degraded due to corrosion. One measure that has been proposed and studied to address this issue is the adhesive bonding method, which can be used to repair and reinforce these structures. However, this method produces brittle fracture in the adhesive layer and is difficult to maintain after bonding. To solve the problem faced by this method, a clarification of the mechanical properties inside the adhesive is necessary. Then this background, a fiber Bragg grating (FBG) sensor has been used in this study. This sensor can be embedded within the building material that needs repairing and reinforcing because an FBG sensor is extremely small. Eventually based on this, a three-point bending test of a carbon fiber reinforced plastic (CFRP) strengthened steel plate that was embedded with an FBG sensor was conducted. This paper demonstrates that an FBG sensor is effectively applicable for sensing when damage occurs.

Organic fluorophores with reversible emission switching behavior are promising materials for applications in sensors, optical recording, security inks, and optoelectronics. A variety of aggregation-induced emission (AIE) luminogens with mechanochromic luminescence has been prepared, and the transformation of efficient bluer-emitting crystals to amorphous powders with redder and weaker emission is proposed to be the cause for such behavior. However, detailed mechanistic understanding from experimental to theoretical is lacking. In this work, we present the design and synthesis of a group of bis(diarylmethylene)dihydroanthracenes with butterfly-like shapes. These molecules exhibit aggregation-induced emission characteristics due to the restriction of intramolecular motion in the aggregated state. They show mechanochromism, because of the transformation between crystal and amorphous states with different colors and efficiencies aided by grinding/heating or solvent fuming processes. By investigation of their single-crystal structures and theoretical calculations, the loose molecular packing with noncovalent intermolecular interactions, the extent of conformational twisting, and the packing density of the luminogens, as well as freedom of intermolecular motion in the excited state, are stemmed for their reversible polymorphism-dependent emission behaviors. © 2015 American Chemical Society.

Structure, magnetic properties, and thermal stability of Sm(1-x)Tm_xCo_5compounds

Structure, magnetic properties, and thermal stability of ternary Sm1-xTmxCo5 compounds were studied via X-ray diffraction（XRD）, thermal magnetic analysis（TMA）, and magnetic measurements. XRD results show that all the compounds have a main phase of hexagonal CaCu5-type crystal structure with small amount of impurity phases; increasing Tm content is associated with contraction of the hexagonal unit cell in the direction of the c axis and expansion of the a and b parameters. TMA results indicate that the Curie temperature（TC） of Sm1-xTmxCo5 compounds gets higher with the increase in Tm *** measurements show that both the magnetic anisotropy field（HA） and the magnetization at an applied field of 7 T（M7 T） decrease with the increase of Tm content. However, the thermal stability of both the HAand M7 Tof all the Tm doped compounds is remarkably improved compared with that of the pure SmCo5 compound, leading to the result that both the M7 Tand HAof Sm0.8Tm0.2Co5 .2are higher than those of SmCo5 compound at 473 K, which indicates the good potential of Tm doped compound in the practical applications at elevated temperature.

Oxidation Behaviors of C-ZrB_2-SiC composite at 2100℃ in Air and O_2

Journal of Materials science & technology 2014年第12期30卷 1223-1229页

The oxidation behaviors of graphite and ZrB2-SiC modified graphite composite were investigated at 2100℃ in1X105 Pa air and 0.2X105 Pa O2. The oxidation tests were conducted in an induction heating furnace. The oxidation of these two materials followed the linear rate law. The determined radius loss rates of graphite and C-ZrB2-Si C at 2100℃ were 2.18X10-2and 1.05X10-2%/s in 1X105 Pa air, and 3.23X10 2 and 2.21X10 2%/s in 0.2X105 Pa O2, respectively. The incorporation of ZrB2 and SiC decreased remarkably the oxidation rate of graphite because the oxide scale formed on the sample surface during oxidation helps in reducing the exposed surface area of the underneath substrate. In two different atmospheres with the same oxygen partial pressure, both graphite and ZrB2-SiC experienced more severe oxidation at 2100℃ in0.2X105 Pa O2than in 1X105 Pa air. The oxidation rate-controlling step for graphite and ZrB2-SiC was proposed to be the inward diffusion of oxygen through the boundary layer and through the pores in the oxide scale, respectively. A model based on diffusion theory was established to discuss the effect of the total gas pressure on their oxidation behaviors.

Supercapacitors, as an emerging energy storage device, have attracted growing interest in recent years. One-dimensional anodic TiO2 nanotube arrays(NTAs) hold great potential as electrode materials for high-performance electrochemical supercapacitors, and also serve as a good scaffold to support other nanoparticles with high specific capacitance. However, their poor electronic conductivity limits their practical applications. Herein, we report on the preparation and electrochemical properties of a novel MnO2/H-TiO2 NTAs composites as electrode materials for supercapacitors. First, hydrogenated TiO2 nanotube arrays(denoted as H-TiO2 NTAs) were obtained by calcination of anodized TiO2 NTAs and electrochemical hydrogenation successively. Then MnO2/H-TiO2 NTAs composites were prepared by loading large amounts of MnO2 nanoparticles onto the walls of H-TiO2 nanotubes through sequential chemical bath deposition(SCBD) method. The as-prepared samples were characterized byX-ray diffraction, field emission scanning electron microscopy, high-resolution transmission electron microscopy and X-ray photoelectron spectroscopy. The electrochemical capacitance performances of as-prepared samples were investigated by cyclic voltammetry and charge-discharge tests in a three-electrode system. The test results show that H-TiO2 NTAs electrodes yield the largest specific capacitance of 11.5 mFcm-2 at a scan rate of 10 mV s–1, which is much higher than the capacitance of air-annealed TiO2 NTAs at the same conditions mainly due to the enhanced carrier density(interstitial hydrogen ions and oxygen vacancies) through electrochemical hydrogenation. Furthermore, MnO2/H-TiO2 NTAs electrodes achieve a remarkable specific capacitance of 484.21 Fg–1 at a scan rate of 10 mV s–1(based on the mass of MnO2) as well as outstanding long-term cycling stability with only 4.2% reduction of initial specific capacitance after 5000 cycles. Developing such novel TiO2 electrode materials should provide new opportu

In this study, the PET/nylon/PET wrapped yarns are made by applying a double warp yarn process. The wrap materials are moisture transferring polyester(PET) yarns and antibacterial nylon yarns, while the core is PET yarns. Such wrapped yarns are made into moisture transferring/antibacterial knits, after which their mechanical properties, antibacterial activity, and water absorbency are evaluated. The test results show that the knits that are composed of wrapped yarns with a wrapping number being 10 turns/cm demonstrate optimal mechanical properties, antibacterial activity, and water absorbency.
