Inorganically coated colloidal quantum dots in polar solvents using a microemulsion-assisted method

Acebrón, María; Herrera, Facundo C.; Mizrahi, Martín; Navío, Cristina; Bernardo-Gavito, Ramón; Granados, Daniel; Requejo, Félix G.; Juarez, Beatriz H.

The dielectric nature of organic ligands capping semiconductor colloidal nanocrystals (NCs) makes them incompatible with optoelectronic applications. For this reason, these ligands are regularly substituted through ligand-exchange processes by shorter (even atomic) or inorganic ones. In this work, an alternative path is proposed to obtain inorganically coated NCs. Differently to…

Micro/macro-stress relationship and local stress distribution in polyethylene spherulites upon uniaxial stretching in the small strain domain

Xiong, Bijin; Lame, Olivier; Seguela, Roland; Men, Yongfeng

Local stress of polyethylene spherulites under uniaxial stretching in small strain domain has been investigated by in-situ wide angle X-ray diffraction (WAXD) in comparison with macroscopic stress. Particular attention is paid to the elastic strain range. The local stress in equatorial and polar regions both increase in absolute value and…

Multilamellar-to-Unilamellar Transition Induced by Diphenylalanine in Lipid Vesicles

Gerbelli, Barbara Bianca; da Silva, Emerson Rodrigo; Miranda Soares, Bruna; Alves, Wendel Andrade; Andreoli de Oliveira, Elisabeth

In the present work, we investigate the effect of two short phenylalanine-based peptides on lipid membranes. A simplified model membrane composed of lecithin vesicles was used to incorporate different amounts of the two amino acid sequences, the dimmer l,l-diphenylallanine (FF) and the trimmer cysteine-diphenylallanine (CFF). Spectroscopic and scattering techniques were…

Nanostructuration effect on the mechanical properties of PMMA toughened by a triblock acrylate copolymer using multilayer coextrusion

Montana, Juan-Sebastián; Roland, Sébastien; Richaud, Emmanuel; Miquelard-Garnier, Guillaume

Multilayer coextrusion was used to obtain nanolayered films of self-assembled commercial triblock copolymer poly(methyl methacrylate-b-butyl acrylate-b-methyl methacrylate) (MAM) confined by poly (methyl methacrylate) (PMMA). A double level of organization is achieved: the obtained films are made of thousands of alternating continuous nanolayers of each component, while within the nanolayers, MAM…
Nano-porous structures via self-assembly of amphiphilic triblock copolymers: influence of solvent and molecular weight

Nano-porous structures via self-assembly of amphiphilic triblock copolymers: influence of solvent and molecular weight

Nehache, S.; Semsarilar, M.; Deratani, A.; In, M.; Dieudonné-George, P.; Him, J. Lai Kee; Bron, P.; Quémener, D.

Control of film structures made from a polystyrene-polystyrene sodium sulfonate-polystyrene (PS-PNaSS-PS) copolymer micellar solution is investigated in a THF/water mixture. Four different copolymers (varying molecular weights) are synthesised via RAFT (Reversible Addition Fragmentation chain Transfer) polymerisation. Depending on parameters such as copolymer molecular weight, solvent composition…

Nonsolvent-induced morphological changes and nanoporosity in poly(L-lactide) films

Shaiju, P.; Murthy, N. Sanjeeva; Gowd, E. Bhoje

The role of a nonsolvent in controlling the crystallization and morphology of solvent-crystallized poly(L-lactide) (PLLA) films was investigated using various microscopy techniques and small- and wide-angle X-ray scattering (SAXS/WAXS). PLLA films crystallized in THF and acetone had 40–80 μm spherulites. When water was present in the solvent, a completely different…
Nanostructured Branched-Chain Carboxylate Ionic Liquids: Synthesis, Characterization, and Extraordinary Solubility for Bioactive Molecules

Nanostructured Branched-Chain Carboxylate Ionic Liquids: Synthesis, Characterization, and Extraordinary Solubility for Bioactive Molecules

Ke, Yuqi; Jin, Wenbin; Yang, Qiwei; Suo, Xian; Yang, Yiwen; Ren, Qilong; Xing, Huabin

The design of multifunctional ionic liquids (ILs) that integrate different attractive characteristics, such as strong hydrogen-bonding interactions, good lipophilicity, significant nanoscale organization, and low viscosity, in a molecular structure is of great importance for the application of ILs in extraction, biomass conversion, and catalysis but remains challenging. Here, we synthesized…
