Facile synthesis of complex multi-component organic and organic–magnetic inorganic nanocomposite particles

22-Nov-2012 | Marco Giardiello; Tom O. McDonald; Phillip Martin; Andrew Owen; Steve P. Rannard, Journal of Materials Chemistry, 2012

A generic in situ method for producing triple component hydrophobic inorganic–organic nanocomposite particles, using a combination of modified emulsion templating and freeze-drying, is presented. Model nanocomposite particles have been developed bearing up to three hydrophobic ingredients chosen ...


Polymer-derived nanoporous silicon carbide with monodisperse spherical pores

21-Nov-2012 | Claudia Hoffmann; Tim Biemelt; Andreas Seifert; Katja Pinkert; Thomas Gemming; Stefan Spange; Stefan Kaskel, Journal of Materials Chemistry, 2012

The synthesis of polymer-derived nanoporous silicon carbide with monodisperse spherical pores is described. An incipient wetness method was used to fill the interparticle voids of microemulsion-derived silica nanospheres with the polycarbosilane SMP-10. The spheres have a very narrow diameter ...


Assembly of oriented iron oxide and zeolite crystals via biopolymer films

21-Nov-2012 | Ming Zhou; Jonas Hedlund, Journal of Materials Chemistry, 2012

Biopolymers are developed as functional intermediate linkers for the assembly of nano and submicron-sized crystals. Mediated by the interlayers, iron oxide and zeolite crystals with varied shapes (cubic, ellipsoidal, and discoidal) are organized into uniformly oriented monolayers on glass plates ...


Nanofiber growth and alignment in solution processed n-type naphthalene-diimide-based polymeric field-effect transistors

21-Nov-2012 | Suhao Wang; Wojciech Pisula; Klaus Müllen, Journal of Materials Chemistry, 2012

The nanofiber growth of an n-type conjugated polymer poly{[N,N′-bis(2-octyldodecyl)-naphthalene-1,4,5,8-bis(dicarboximide)-2,6-diyl]-alt-5,5′-(2,2′-bithiophene)}, P(NDI2OD-T2), was studied during solution processing. Highly reproducible fibrous nanostructures obtained at various dip coating ...


Synthesis and characterization of in situ Fe2O3-coated FeF3 cathode materials for rechargeable lithium batteries

21-Nov-2012 | Wei Zhang; Lin Ma; Hongjun Yue; Yong Yang, Journal of Materials Chemistry, 2012

Here, a novel architecture of a core–shell structured FeF3@Fe2O3 composite with particle size of 100–150 nm and tunable Fe2O3 content is synthesized by a simple heat treatment process utilizing FeF3 with fine network structure as precursor. The structure, morphology and electrochemical ...


Creation of nanoporous tantalum (Ta)-incorporated titanium (Ti) surface onto Ti implants by sputtering of Ta in Ar under extremely high negative substrate biases

21-Nov-2012 | Vuong-Hung Pham; Tae-Sik Jang; Hyun-Do Jung; Hyoun-Ee Kim; Young-Hag Koh, Journal of Materials Chemistry, 2012

The development of new surface modification techniques for improving the biological performances (i.e., osseointegration) and long-term stability of Ti implants is one of the most active research areas in dental and orthopedic implant industries. We herein propose a novel, simple way of creating ...


Here's to the future

21-Nov-2012 | Journal of Materials Chemistry, 2012

Liz Dunn (Editor) and Seth Marder (Chair of the Editorial Board) commemorate Journal of Materials Chemistry and look back over some of the highlights of the last 22 years.


Near-infrared photoluminescence from molecular crystals containing tellurium

21-Nov-2012 | Hong-Tao Sun; Yoshio Sakka; Naoto Shirahata; Minoru Fujii; Tetsu Yonezawa, Journal of Materials Chemistry, 2012

We report the observation of near-infrared photoluminescence from Te4(Ga2Cl7)2 and Te4(Al2Cl7)2 molecular crystals containing Te42+ polycations. The experimental and theoretical results clearly revealed that the Te42+ polycation is a smart near-infrared emitter with characteristic emission peaks ...


Pyrene-directed growth of nanoporous benzimidazole-linked nanofibers and their application to selective CO2 capture and separation

15-Nov-2012 | Mohammad Gulam Rabbani; Ali Kemal Sekizkardes; Oussama M. El-Kadri; Bilal R. Kaafarani; Hani M. El-Kaderi, Journal of Materials Chemistry, 2012

A pyrene-based benzimidazole-linked polymer (BILP-10) has been synthesized by the co-condensation of 1,3,6,8-tetrakis(4-formylphenyl)pyrene and 1,2,4,5-benzenetetramine tetrahydrochloride in dimethylformamide. The use of pyrene as a molecular building unit leads to the formation of self-assembled ...


Lipophilic and cationic triphenylphosphonium grafted linear polyethylenimine polymers for efficient gene delivery to mammalian cells

15-Nov-2012 | R. Bansal; S. K. Tripathi; K. C. Gupta; P. Kumar, Journal of Materials Chemistry, 2012

Synthetic chemical vectors have recently provided a versatile and robust platform for the safe and efficient delivery of exogenous genes. Here, for the first time, a small series of N-butyltriphenylphosphonium bromide-grafted-linear polyethylenimine (BTP-g-lP) polymers (N–P hybrid polymers) have ...
