In this work, carbon quantum dots (CQDs) have been synthesized by one step hydrothermal method to detect hydrogen peroxide (H2O2). The optical H2O2 sensors were based on the fluorescent quenching of the carbon quantum dots. The optical H2O2 sensors demonstrate capable of detecting H2O2 over the range of 0-88.2 mM and…
A polycrystalline ZnO thin film prepared by atomic layer deposition was annealed in hydrogen at 10 bar and 350-450 °C. Hydrogenation induced simultaneous formation of oxygen and zinc vacancies whose concentrations were closely related to the temperature of treatment. Spatial distributions of these defects were analyze…
An in situ preparation strategy was developed via thermal decomposition towards highly active supported Pt nanocatalysts for high-temperature catalytic dehydrogenation reactions.
A novel TGFβ1 inhibitor delivery system based on fluoro-magnetic nanoparticles (fluoro-MNPs) is developed.
A sensor array consisting of six cationic fluorescent conjugated polyelectrolytes (CPEs) is reported, which could readily differentiate between nine closely related hydrophilic nitroaromatics (NACs) in separate aqueous solutions by fluorescence pattern recognition and linear discrimination analysis (LDA).
The effect of a growth mechanism on the unit cell strain and the related change in the properties of single-crystal Ba 0.8 Sr 0.2 TiO 3 films grown on MgO substrates according to the Frank–van der Merwe and Volmer–Weber growth mechanisms is studied. The unit cell strain is shown to depend substantially on the film thi…
Abnormal phase transition of VO 2 nanoparticles was observed after high-temperature thermal treatment. A single phase transition temperature at 65.1 °C for the pristine VO 2 nanoparticles split into two temperatures of approximately 74 °C and 84 °C.
A covalently anchored and spatially confined organic polymer was formed in a layered compound with a surface-modified layer. The resultant anchored and confined polymer showed tunable photochemical properties with the incorporation of a variety of guest molecules originating from the specific incorporation states. The…
4-( N -Carbazolyl)triphenylamine ( TPACz ) and its methoxy derivative MeOTPACz could be facilely fabricated into redox-active and electrochromic PTPACz polymer and (MeOTPACz)2 dimer films via electrochemical polymerization.
Temperature-dependent synthesis of hexagonal, disk-like and octahedron-like Bi–Se nanocrystals.
The perovskite structure is widely considered ideal host phases for Sr immobilization. To investigate the radiation tolerance on ceramic waste forms, the as-prepared SrZrO 3 ceramics were irradiated by external electron beam. The results indicated that the electron irradiation had different influence on the surface an…
The controllable morphology and crystalline phase of manganese oxides formed in the Hummer's method have an impact on the electrocapacitive performance of the resulting composite materials.
This paper deals with dielectric properties of hydrocarbon-based thermosetting resin to evaluate the applicability to electrical insulating materials. Higher thermal stability is needed for various devices as well as electrical insulating materials. Moreover, higher withstand voltage, lower dielectric constant and low…
Based on the bianalyte method, time-dependent surface-enhanced Raman spectrosopy (SERS) spectra were applied to observe and study the competitive adsorption of bipyridine isomerides 2,2'-bpy and 4,4'-bpy. These time-dependent SERS spectra offer a significant advantage for observing the continuous SERS spectra of analy…
Three new flavonoid glycosides named isolinariins C, D and E (1-3), two known flavonoid glycosides (4, 5) and three known flavonoids (6-8) were isolated from the whole plant of Linaria japonica. The structures of these compounds were determined mainly by spectroscopic analyses. The bioactivities of these isolated comp…
The article reports a polyacrylonitrile-derived hierarchical porous carbon nanospheres as high-performance supercapacitors via a green, facile and efficient strategy.
Silicon carbide with 50 mass% zirconia ceramic matrix composites were processed by mechanical milling (MM) followed by spark plasma sintering (SPS). By controlling the parameters of MM and SPS, an ultra-fine ZrO2 grain was homogeneously dispersed and refined on the surface of a fine SiC powder, forming a harmonic micr…
The 62 μm-thick, 1.09 g cm −3 -dense hybrid electrode of 82 wt% MnO 2 and 18 wt% CNTs realized high total capacitances of 120 F g −1 , 131 F cm −3 , and 0.81 F cm −2 at 2 mV s −1 scan rate.
A new indane based electron acceptor fragment has been developed and can be used to acquire NLO active chromophores with controlled stereochemistry.
We explore two strategies to improve the performance of hybrid solar cells fabricated using poly(3-hexylthiophene) (P3HT) and colloidal PbSe nanocrystals, which have reached a 1 sun power conversion efficiency of 2.9%.
