Photochromic molecules are widely applied in chemistry, physics, biology, and materials science. Although a few photochromic systems have been developed before, their applications are still limited by complicated synthesis, low fatigue resistance, or incomplete light conversion. Rhodamine is a class of dyes with excel…
Atomic layers of two-dimensional (2D) materials have recently been the focus of extensive research. This follows from the footsteps of graphene, which has shown great potential for ultrathin optoelectronic devices. In this paper, we present a comprehensive study on the synthesis, characterization, and thin film photod…
The quantitative correlation of the catalytic activity with the microscopic structure of heterogeneous catalysts is a major challenge for the field of catalysis science. It requests synergistic capabilities to tailor the structure with atomic scale precision and to control the catalytic reaction to proceed through wel…
Monodisperse Mn 3 O 4 nanoparticles were prepared solvothermally starting from manganese acetate by using polyether amide block copolymers (Pebax2533) as a template in isopropanol. The diameter of the nanoparticles in the range of 8.7 nm∼31.5 nm was decreased with increase of Pebax2533 concentration. The electrochemic…
The decomposition of nitric oxide (NO) was studied over carbon nanotubes (CNTs) supported Cu–Mn catalyst. CNTs were home-made by cracking of methane over the LaNiO3 catalyst. At the temperature of 500°C, 71.8% NO was decomposed into N2 (71% selectivity) with the by-products of NO2 and N2O (29% selectivity in total). X…
In this paper, we have synthesized meso-oxides (i.e., Co 3 O 4 and NiO ) by using mesoporous silica as hard template. The microstructures and chemical compositions of the corresponding meso-oxides were characterized by the Transmission electron microscope-selected area electron diffusion (TEM-SAED), X-ray diffraction…
In this paper, cross-plane thermal conductivities of the nanoporous glass alumina film (NGAF) and its composites ( Ag /NGAF, with Ag nanowires embedded in) were measured. And a model was setup to predict the thermal conductivity of the nanoporous material. Results show that the thermal conductivity of the NGAF is abou…
Abstract Supramolecular cation salt of adamantane rotator with a dithiolene complex, (fluoroadamantylammonium+)([18]crown-6)[Ni(dmit)2]− (1) was synthesized. The fluorine atom of the adamantane unit showed a large thermal factor elongated latitudinally, suggesting molecular rotation in the solid state. Crystal 1 exhib…
SrBi2Nb2O9 nanoplates were successfully synthesized by a hydrothermal method for the first time, using Sr(NO3)2, Bi2O3, and Nb2O5 as the starting materials and KOH as the mineralizer. The influences of the reaction conditions on the phases and morphologies of the products were investigated by X-ray diffraction (XRD) a…
Magnesia (MgO) nanoparticles were produced from magnesite ore (MgCO 3 ) using ball mill. The crystalline size, morphology and specific SSA were characterized by X-ray diffraction analysis, transmission electron microscopy and Brunauer-Emmett-Teller method, respectively. MgO nanoparticle-incorporated nylon 6 solutions…
Na 2 SO 4 , Na 2 SO 4 : Li, and Na 2 SO 4 : Li, Eu, Dy phosphors were prepared by using slow evaporation technique followed by subsequent calcination at 400°C for 4 h. Doping with Li + ion stabilized the thenardite phase of host matrix, while codoping with RE 3+ stabilized the phase transformation from stable thenardi…
Abstract Ni‐base metal–intermetallic laminate composites were obtained from in situ reaction synthesis between Ni and Al foils by utilizing plasma activated sintering. The effects of Ni foil thickness on the microstructure and tensile properties of the composites were investigated. The results show that the phases for…
The magnetic and thermal properties of Ce1−xErxAl2 compounds have been studied using specific heat, dc magnetization, and ac susceptibility measurements. All these compounds are isomorphic with the MgCu2 Laves phase, and the lattice parameter decreases almost linearly with the increasing Er concentration x. The dc mag…
By conjugating antibodies on magnetic nanoparticles, target antigens can be quantitatively detected by measuring the magnetic signals of the magnetic nanoparticles due to their association with target antigens. This method of detection is called magnetically labeled immunoassay. The assay characteristics of magnetical…
The thermally stimulated depolarization current (TSDC) technique has been used to study the slow molecular mobility in the amorphous part of the semicrystalline polymer, poly(ethylene oxide) (PEO). Experiments were carried out in the temperature range that includes the glassy state, the glass transformation region and…
The results of spectroscopic studies of the diffraction anomalies (the so-called resonant Wood anomalies) in spatially periodic hybrid structures based on chalcogenide ${\mathrm{Ge}}_{2}{\mathrm{Sb}}_{2}{\mathrm{Te}}_{5}$-coated opal films of various thickness are presented. A theoretical analysis of spectral-angular…
Optimization of thin‐film transistors performance is usually accompanied by an increase of the process temperature. This work presents a method to raise the field effect mobility by a factor of 3 without a change of the process parameters. The modification involves a solution doping process where an ammine zinc comple…
Catalytically synthesized methanol from H2 and CO2 using porous Cu/ZnO aggregates is a promising, carbon neutral, and renewable alternative to replace fossil fuel based transport fuels. However, the absence of surface-engineered model systems to understand and improve the industrial Cu/ZnO catalyst poses a big technol…

The production of nanoparticles from solution typically involves the use of complex solution additives or particle functionalization with organic ligands to prevent aggregation. Another approach would be to produce the particles within a nanoscale environment, such as inside a micelle. In this contribution, we produce…
