Aggregation induced emission switching and electrical properties of chain length dependent [small pi]-gels derived from phenylenedivinylene bis-pyridinium salts in alcohol-water mixtures

31-10-2012 | Suman K. Samanta; Santanu Bhattacharya, Journal of Materials Chemistry, 2012

Supramolecular π-gels were formed in a mixture of aliphatic alcohols and water for a series of chromophoric phenylenedivinylene bis-N-alkyl pyridinium salts (PPV) appended with terminal aliphatic hydrocarbon chains of different lengths. Gelation could be controlled either by altering the ratio of ...

Gd(III)-doped carbon dots as a dual fluorescent-MRI probe

31-10-2012 | Athanasios B. Bourlinos; Aristides Bakandritsos; Antonios Kouloumpis; Dimitrios Gournis; Marta Krysmann; Emmanuel P. ..., Journal of Materials Chemistry, 2012

We describe the synthesis of Gd(iii)-doped carbon dots as dual fluorescence-MRI probes for biomedical applications. The derived Gd(iii)-doped carbon dots show uniform particle size (3–4 nm) and gadolinium distribution and form stable dispersions in water. More importantly, they exhibit bright ...

Hierarchically designed injectable hydrogel from oxidized dextran, amino gelatin and 4-arm poly(ethylene glycol)-acrylate for tissue engineering application

25-10-2012 | Xiaohua Geng; Xiumei Mo; Linpeng Fan; Anlin Yin; Jun Fang, Journal of Materials Chemistry, 2012

Hydrogels are high in water content and have physical properties similar to native extracellular matrix (ECM), and thus they have been widely studied as three-dimensional (3D) tissue engineering scaffolds for cell culture. In this work, a two-step process was introduced to fabricate injectable ...

Managing wetting behavior and collection efficiency in photoelectrochemical devices based on water electrolytes; improvement in efficiency of water/iodide dye sensitised cells to 4%

24-10-2012 | ChunHung Law; Omar Moudam; Silvia Villarroya-Lidon; Brian O'Regan, Journal of Materials Chemistry, 2012

We have fabricated Dye Sensitised Solar Cells (DSSCs) using only water as the solvent and guanidinium iodide–iodine as the redox couple that operate at 4% energy efficiency under 1-sun illumination. This result is [[similar]] 5 times higher than the best previously reported values. We show that ...

Solvothermal Synthesis of Nano-LiMnPO4 from Li3PO4 Rod-like Precursor: Reaction Mechanism and Electrochemical Properties

24-10-2012 | Shiliu Yang; Ru-Guang Ma; Ming-Jun Hu; Liu-Jiang Xi; Zhouguang Lu; C. Y. Chung, Journal of Materials Chemistry, 2012

A simple one-pot solvothermal approach is employed to synthesis LiMnPO4 (LMP) nanomaterials by using Li3PO4 nanorods and MnSO4H2O as the precursors. Various experimental parameters such as volume ratio of polyethylene glycol 600 (PEG 600) to water, reactant feeding order, reaction time, pH value ...

Facile fabrication of tin-doped hematite photoelectrodes – effect of doping on magnetic properties and performance for light-induced water splitting

10-10-2012 | Jiri Frydrych; Libor Machala; Jiri Tucek; Karolina Siskova; Jan Filip; Jiri Pechousek; Klara Safarova; Martin Vondra ..., Journal of Materials Chemistry, 2012

We present a new, easily scalable method for the deposition of nanocrystalline hematite photoelectrodes based on the spin-coating of a mixed solution containing tin(ii) and iron(iii) chlorides followed by thermal treatment. Our facile approach does not require any additional film-forming organic ...

In situ chemical reduction of the Ta3N5 quantum dots coupled TaON hollow spheres heterojunction photocatalyst for water oxidation

10-10-2012 | Zheng Wang; Jungang Hou; Shuqiang Jiao; Kai Huang; Hongmin Zhu, Journal of Materials Chemistry, 2012

Photocatalytic oxygen evolution with a high efficiency was achieved using tantalum nitride (Ta3N5) quantum dots (QDs) coupled TaON hollow spheres (Ta3N5–TaON). TaON hollow spheres coupled with the surface enriched Ta3N5 QDs were prepared by an in situ chemical reduction route in ammonia solution ...

Preparation, characterization and reaction mechanism of a novel silver-organic conductive ink

10-10-2012 | Yu Chang; Dong-Yu Wang; Yan-Long Tai; Zhen-Guo Yang, Journal of Materials Chemistry, 2012

A novel silver-organic conductive ink with no particle, consisting of silver-amide complex dispersed in glycol mixed water, was developed in a simply way. Reaction mechanism during sintering was also studied and a multi-mechanism was found for the first time. Silver ion in solvent can be reduced ...

A facile route to (ZnS)x(CuInS2)1−x hierarchical microspheres with excellent water-splitting ability

04-10-2012 | Yuhan Lin; Fang Zhang; Daocheng Pan, Journal of Materials Chemistry, 2012

A series of (ZnS)x(CuInS2)1−x hierarchical micro/nano-structured solid solutions with precisely controlled chemical composition were synthesized via a facile one-pot solvothermal method. ZnO, Cu2O, and In(OH)3 are used as the starting materials and dissolved in ethanol dithiocarbamic acid which ...
