PMID: 25437170
Chimia (Aarau). 2014 Oct;68(10):746-7. doi: 10.2533/chimia.2014.746.

Chemical incidents are typically caused by loss of control, resulting in runaway reactions or process deviations in different stages of the production. In the case of fed-batch reactors, the problem generally encountered is the accumulation of heat. This is...

Analysis of Fine Bubble Attachment onto a Solid Surface within the Framework of Classical DLVO Theory.

Journal of colloid and interface science

Yang C, Dabros T, Li D, Czarnecki J, Masliyah JH.
PMID: 10527573
J Colloid Interface Sci. 1999 Nov 01;219(1):69-80. doi: 10.1006/jcis.1999.6421.

Fine bubble attachment onto a solid surface in an impinging jet flow was analyzed within the framework of DLVO theory. The effects of hydrodynamic convection, van der Waals (VDW) interaction, electrostatic double-layer (EDL) interaction, and gravitational force on bubble...

Chemistry (Weinheim an der Bergstrasse, Germany)

Darwish AD, Avent AG, Boltalina OV, Gol'dt I, Kuvytchko I, Da Ros T, Street JM, Taylor R.
PMID: 12740847
Chemistry. 2003 May 09;9(9):2008-12. doi: 10.1002/chem.200204549.

Co-evaporation of solutions of C(60)F(18) and tetrathiafulvalene in toluene produces an unsymmetrical C(60)F(16):tetrathiafulvalene adduct through a unique six-electron cycloaddition involving displacement of two fluorine atoms by a terminal Cdbond;C double bond of the fulvalene. The adduct rearranges into two...

Fractal structure of asphaltene aggregates.

Journal of colloid and interface science

Rahmani NH, Dabros T, Masliyah JH.

J Colloid Interface Sci. 2005 May 15;285(2):599-608. doi: 10.1016/j.jcis.2004.11.068.

A photographic technique coupled with image analysis was used to measure the size and fractal dimension of asphaltene aggregates formed in toluene-heptane solvent mixtures. First, asphaltene aggregates were examined in a Couette device and the fractal-like aggregate structures were...

Demonstration of effective control of fast-ion-stabilized sawteeth by electron-cyclotron current drive.

In a tokamak plasma, sawtooth oscillations in the central temperature, caused by a magnetohydrodynamic instability, can be partially stabilized by fast ions. The resulting less frequent sawtooth crashes can trigger unwanted magnetohydrodynamic activity. This Letter reports on experiments showing...

INTRODUCTION: Limb salvage with endoprosthetic reconstruction is the standard of care for the management of lower-extremity bone tumours in skeletally mature patients. The risk of deep postoperative infection in these procedures is high and the outcomes can be devastating....

Luminescent blooming of dendronic carbon nanotubes through ion-pairing interactions with an Eu(III) complex.

Chemistry (Weinheim an der Bergstrasse, Germany)

Maggini L, Toma FM, Feruglio L, Malicka JM, Da Ros T, Armaroli N, Prato M, Bonifazi D.

A multiwalled carbon nanotube (MWCNT) scaffold was covalently functionalized with a second-generation polyamidoamine (PAMAM) dendron, presenting four terminal amino groups per grafted aryl moiety. These reactive functions were alkylated to obtain a positively charged polycationic dendron/carbon nanotube system (d-MWCNTs⋅Cl),...
