Remanufacturing is an active area of research due to its cost saving capabilities and emission-reduction benefits. After being disassembled, cleaned and inspected, the core components go through a series of reconditioning operations before being reassembled into the final remanufactured product, and tested to ensure q…
As an engineering material derived from renewable resources, wood possesses excellent mechanical properties in view of its light weight but also has some disadvantages such as low dimensional stability upon moisture changes and low durability against biological attack. Polymerization of hydrophobic monomers in the cel…
A novel magnetic nano-CoFe2O4supported Sb ([CoFe2O4@SiO2-DABCO-Sb]) was successfully constructed and identified as an efficient catalyst for synthesis of multisubstituted pyrrolesviaone-pot three-component reaction of amines, nitroolefin and 1,3-dicarbonyl compounds.
Electrospinning is useful for fabricating nanofibrous structure with different composition and morphologies. It offers great advantages through its geometrical structure and biomimetic property, which can provide a suitable environmental site for cell growth. The fiber diameter is entangled by the concentration of PCL…
Zinc exchanged heteropoly tungstates (Zn x TPA) are highly active catalysts for the synthesis of glycerol carbonate from glycerol and urea. The activity depends on the number of Zn 2+ ions in the secondary structure of heteropoly tungstate.

Layered photocatalyst Bi 2 O 2 [BO 2 (OH)] nanosheets efficiently separated photogenerated carriers due to the internal polar electric field, which enhances the photocatalytic activity.
Core–shell structures as LiFePO4@carbon with a continuous and uniform carbon coating were achieved by means of the in situ polymerization of dopamine. Systematic control of the coating layer identified that a 5 nm carbon coating produces the best battery performance. Our results provide conclusive evidence for an opti…
Mechanism clarification of the phase transformation in the three stages, i.e. initial crystallization, stretching and poling.
In this work, in situ transmission electron microscopy heating has been used to investigate the effects of a carbon capping layer on sintering of silver nanoparticles. For the first time, we make direct and real-time measurements of surface diffusivity of silver in nanoparticles coated with carbon. We observe that the…
The solution-shearing technique is utilized to fabricate large-area, ultrathin and continuous films of 1,4-bis((5′-hexyl-2,2′-bithiophen-5-yl)ethynyl)benzene (HTEB) for high-performance organic thin-film transistors (OTFTs), based on which highly sensitive, highly selective and reversible gas sensors exhibit outstandi…
The cleavage of C-S linkages plays a key role in fuel processing and organic geochemistry. Water is known to affect these processes, and several hypotheses have been proposed, but the mechanism has been elusive. Here we use both experiment and theory to demonstrate that supercritical water reacts with intermediates fo…
We present a facile method for producing anti-fogging (AF) and anti-reflection (AR) coating functionalized photoanodes via one-step SiO2 nanoparticle coating for high performance solid state dye-sensitized solar cells (ssDSSCs). The AF and AR coating functionalized photoanodes are prepared by spin-coating of partially…
A stable porous Ag(I)-MOF with new topology is constructed from AgSbF6 and 3,6-bis[2-(4-oxide-quinoxaline)-yl]-4,5-diaza-3,5-octadiene (L). This compound can be a highly selective porous MOF material to effectively separate benzene from its six-membered cyclic organic analogues such as cyclohexane, cyclohexene and o-,…
Novel In 2 O 3 /La 2 Ti 2 O 7 nanostructured heterojunction photocatalysts can promote the fast separation of photogenerated carriers and improve photocatalytic water splitting H 2 production.
The present work provides a simple approach for the surface modification of an acid activated montmorillonite clay with both acid and base (–SO3H and –NH2) functional groups. FTIR, 29Si and 13C CP MAS NMR spectroscopy studies confirm the grafting of the organic functional moieties. These materials were also extensivel…
In this work, novel CeCO3OH@C nanocomposites were prepared via a one-pot approach by hydrothermal carbonization of a solution of glucose as a carbon precursor in the presence of Ce(NO3)3·6H2O and urea. It was found that glucose not only facilitates the formation of CeCO3OH nanoparticles, but also leads to a uniform, g…
A molecular simulation study is reported for biofuel purification in six zeolitic imidazolate frameworks (ZIF-8, -25, -71, -90, -96 and -97) with different functional groups. For pure ethanol and water, the predicted adsorption isotherms agree fairly well with experimental data. Hydrogen bonding has an important effec…
Cobalt (Co) has been considered as one of the candidates for the barrier material in copper (Cu) interconnects. As a metal that is less noble than copper, Co poses two challenges to the integration scheme. For example, during the post-chemical mechanical planarization (CMP) cleaning step, corrosion of Co and galvanic…
One important innovation of green construction material is natural polymer modified mortar. In this research, polymer modified mortar used natural polymer from seaweeds, they are Eucheuma Cottonii (gel) and Gracilaria Sp. The research conducted in two parts, pre-experiment and main-experiment. Pre-experiment aimed to…
