Tension–twisting dependent kinematics of chiral CNTs

Autor: Jos Nun Canon Lop, Nuno Silvestre, Bruno Faria, Jose Nuno Canongia Lopes

Publikováno v: Composites Science and Technology. 74:211-220

This paper shows that chiral carbon nanotubes (CNTs) under twisting show highly dependent strength and fracture toughness on (i) the level of axial tension and (ii) the direction of twisting. To achieve this conclusion, numerous computational intensi

A molecular dynamics study on the thickness and post-critical strength of carbon nanotubes

Autor: Jos Nun Canon Lop, Nuno Silvestre, Bruno Faria, Jose Nuno Canongia Lopes

Publikováno v: Composite Structures. 94:1352-1358

This paper presents a molecular dynamics (MDs) study on the linear, buckling and post-buckling behaviour of carbon nanotubes (CNTs) under pure shortening and pure twisting. Its objectives are (i) to clarify the issue about the most correct thickness

Partition Coefficients of Alkaloids in Biphasic Ionic-Liquid-Aqueous Systems and their Dependence on the Hofmeister Series

Autor: Ana Rita Teles, Luis Paulo Rebelo, Isabel Marrucho, Jos Nun Canon Lop, Jose Nuno Canongia Lopes, Mara Freire, Joao Coutinho

Publikováno v: Separation Science and Technology. 47:284-291

The aim of this work is to test the potential of hydrophobic phosphonium-based ionic liquids for the extraction of caffeine and nicotine from aqueous phases through the determination of the alkaloids’ partition coefficients. It was found that the c

Interaction diagrams for carbon nanotubes under combined shortening–twisting

Autor: Jos Nun Canon Lop, Nuno Silvestre, Bruno Faria, Jose Nuno Canongia Lopes

Publikováno v: Composites Science and Technology. 71:1811-1818

A theoretical investigation on the strength and stiffness of carbon nanotubes (CNTs) under combined shortening and twisting strains is presented. CNTs with similar length-to-diameter aspect ratios, L/D, but different atomic structures (zig-zag, armch

Publikováno v: Journal of Chemical & Engineering Data. 56:4356-4363

The melting temperatures of [Cnmpy]Cl (4 ≤ even n ≤ 18) were determined by a dynamic method and confirmed by differential scanning calorimetry. The latter technique was also used to measure the corresponding enthalpies of fusion. The temperatures

Viscosity of (C2–C14) 1-alkyl-3-methylimidazolium bis(trifluoromethylsulfonyl)amide ionic liquids in an extended temperature range

Autor: Luis Paulo Rebelo, Isabel Marrucho, Jos Nun Canon Lop, Mohammad Tariq, Pedro Carvalho, Jose Nuno Canongia Lopes, Joao Coutinho

Publikováno v: Fluid Phase Equilibria. 301:22-32

Dynamic viscosities of several members of the 1-alkyl-3-methylimidazolium bis(trifluoromethylsulfonyl)amide, [Cnmim][NTf2], ionic liquids family, with the cation alkyl side-chain length varying from 2 to 14 carbon atoms, have been measured in the 278

Mutual Solubility of Water and Structural/Positional Isomers of N-Alkylpyridinium-Based Ionic Liquids

Autor: Luis Paulo Rebelo, Isabel Marrucho, Carlos Bernardes, Jos Nun Canon Lop, Karina Shimizu, Catarina Seiça Neves, Jose Nuno Canongia Lopes, Mara Freire, Joao Coutinho

Publikováno v: The Journal of Physical Chemistry B. 114:15925-15934

Despite many previous important contributions to the characterization of the liquid-liquid phase behavior of ionic liquids (ILs) plus water systems, a gap still exists as far as the effect of isomers (of ILs) is concerned. Therefore, in this work, a
