This study investigates treating polyethylene terephthalate (PET) waste water bottles with different mass of ethylene glycol (EG) using reactive extrusion technique at a temperature of 260°C. The study puts emphases on evaluating the thermal, mechanical, and chemical characteristics of the treated polyethylene terepht…
Single-crystal microsheets of a novel dimeric phthalocyanine are successfully obtained <italic>via</italic> a facile solution process with excellent carrier mobilities of 18 cm <sup>2</sup> V <sup>−1</sup> s <sup>−1</sup> for hole and 0.3 cm <sup>2</sup> V <sup>−1</sup> s <sup>−1</sup> for electron, respectively.
in 7-RE, also play a crucial role in determining the structures of these complexes. Structure evolutions make these complexes present various luminescent emissions. Complexes 3-Tm, 3-Yb, 3-Lu, 3-Y and 4-Lu exhibit ultraviolet emissions from 354 to 370 nm. Complexes 1-La and 6-La present blue emissions at 442 and 463 n…
An acrylamide modified α-zirconium phosphate was prepared by intercalating acrylamide into the α-zirconium phosphate, and was utilized to synthesize a flame retardant phosphorus-containing nanocomposite <italic>via in situ</italic> emulsion polymerization.
Electric field gradients in weakly ferromagnetic CaFe 2 O 5 remarkably change below T N , because of local electric polarizations induced by Dzyalosinskii-Moriya interactions.
The design of the elastic ring compensator of «press-and-die” system errors, the method and software for calculating its geometric parameters are given in the article. The developed method is based on the account of unevenness of the radial and altitudinal deformation (barrel-type shape) of the elastic working element…
gel electrolyte). A capacitance retention of above 90% (up to 180° folding angle) after 50 bending-relaxing cycles is obtained, implying the superior durability of the device and the worthiness of the synthesis procedure. The method reported here may pave the way for the development of an environment friendly, large s…
A facile and efficient method is used to synthesize porous iron oxide coated with graphene as electrode materials for lithium-ion batteries and supercapacitors.
Carbazole-based BODIPY dimers 2a-g were synthesized via direct arylation. They showed red-shifted solid-state fluorescence spectra as compared with the corresponding monomer. In addition, unsymmetrical dimers 2d, 2f, and 2g with two different substituents showed red fluorescence with improved quantum yields in the sol…
, suggesting that the glass ceramic is a promising gain material that can be applied to broadband amplifiers in the mid-infrared region. Furthermore, energy transfer mechanisms in glass and glass ceramics were proposed based on visible to mid-infrared emission spectra. It was found that the change in the photon energy…
The flammability issue of textile materials employed in business uniforms becomes an important part in the management of worker safety, as in the case of electricians or kitchen chefs. Among the categories that wear business uniforms, the aeronauts are trained among other activities to fight fire on board. It is part…
The differences between the Ti–C and Ti–Si chemical bonds limit the passivation ability, resulting in a decreased passivation ability.
Three new sulfides with large band gaps, NCS Ba <sub>4</sub> Ga <sub>4</sub> SnS <sub>12</sub> , CS Ba <sub>12</sub> Sn <sub>4</sub> S <sub>23</sub> and Ba <sub>7</sub> Sn <sub>3</sub> S <sub>13</sub> were synthesized for the first time. Ba <sub>4</sub> Ga <sub>4</sub> SnS <sub>12</sub> exhibits a desired balance betw…
NW film achieves non-invasive, direct detection of real-world surfaces due to its high sensitivity, high flexibility and optically transparent properties.
InN phase was successfully integrated into TiO <sub>2</sub> fiber, which greatly improved its visible-light photocatalytic property.
Considering the importance of metal nano catalysts, this research tries to apply sputtered nanoparticles as catalyst for growing carbon nanotubes and studies the effect of metals in modifying the catalytic property. One and bilayer Cu and Fe thin films were placed inside a quartz tube reactor to synthesis carbon nanot…
Ag–ZnO nanocomposites are conveniently prepared on alloy substrates, leading to much improved field emission performances.
