Broom-like and flower-like heterostructures of silver molybdate through pH controlled self assembly
(2012)Silver molybdate microrods are selfassembled into micron sized, broom-like and flowerlike structures. Our investigations indicate that through a simple hydrothermal process, large scale production of such structure is ...

A chiral dumbbell shaped bis(fullerene) oligoelectrolyte
(2007)The first icosacationic bis(fullerene) whose water solubility is provided by twenty peripheral ammonium groups has a rigid, almost cylindrical shape and was synthesized by connecting two fullerene cores with a chiral ...

Design and synthesis of new nanosized C 3-symmetrical tricarboxylic acids: Key elongated ligands for the preparation of highly porous MOFs
(2015)The synthesis of two new C 3-symmetrical nanosized tricarboxylic acids bearing triphenylmethane cores and three imines linkages is presented. The new elongated tripods were designed to stabilise highly porous metal-organic ...

Design considerations for nanotherapeutics in oncology
(2015)Nanotherapeutics have improved the quality of life of cancer patients, primarily by reducing the adverse effects of chemotherapeutic agents, but improvements in overall survival are modest. This is in large part due to the ...

Direct photon cross section with conversions at CDF
(2004)We present a measurement of the isolated direct photon cross section in p p̄ collisions at √s = 1.8 TeV and |η| T is poorly described by next-to-leading-order QCD predictions, but agrees with previous CDF measurements.

The effect of natural organic matter on the formation and solubility of M(OH)4 solid phases
(2014)In this study the formation of M(OH)4 solid phases (e.g. Th(IV), Ce(IV) and Zr(IV)) has been investigated as a function of the natural organic matter (NOM) concentration in 0.1 M NaClO4, in the pH range between 2 and 5, ...

An efficient computational fluid-particle dynamics method to predict deposition in a simplified approximation of the deep lung
(2018)High-fidelity simulations of the complete airway tree are still largely beyond current computational capabilities. Towards large-scale simulations of the human lung, the current study introduces a numerical methodology to ...

Normalization of tumour blood vessels improves the delivery of nanomedicines in a size-dependent manner
(2012)The blood vessels of cancerous tumours are leaky and poorly organized. This can increase the interstitial fluid pressure inside tumours and reduce blood supply to them, which impairs drug delivery. Anti-angiogenic ...

The phenol steam reforming reaction over MgO-based supported Rh catalysts
(2004)The phenol steam reforming reaction toward H2 formation has been investigated in the 575-730°C range over MgO, CeO2, and ZrO 2 single metal oxides and various mixed metal oxides such as Mg-Ce-O, Mg-Zr-O, and Mg-Ce-Zr-O, ...
