Nanocomposites of titanium dioxide and polystyrene-poly(ethylene oxide) block copolymer as solid-state electrolytes for lithium metal batteries

There is considerable interest in developing solid electrolytes for rechargeable lithium batteries as they have the potential to increase both energy d. due to incorporation of a lithium metal anode and safety of batteries due to the fact that they are non ...

The Presence of Ultralow Densities of Nanocrystallites in Amorphous Poly(lactic acid) Microspheres

Sylvie Roke, Hilton Barbosa De Aguiar

Ultralow densities of crystalline nanospheres have been detected in amorphous polymer microspheres by utilizing the unique sensitivity of second-order nonlinear optical techniques to anisotropy. Vibrational sum frequency scattering (SFS) and X-ray diffract ...

Measuring the mesh size of hydrogels

Mohamadreza Nassajian Moghadam

Hydrogels are cross-linked, water-swollen polymer networks that are widely used as a biomaterial. Because of high amount of water, they are mechanically poor and soft. This aspect limits their applications. The suitability of hydrogels as biomedical materi ...

In-plane conduction of polymer composite plates reinforced with architectured networks of Copper fibres

Véronique Michaud

Model composite plates composed of highly conductive slender copper fibres impregnated with a poorly conductive and transparent PMMA matrix were processed with different fibrous architectures, i.e. with various controlled fibre contents and orientations. T ...

Polymer micelles with pyridyl disulfide-coupled antigen travel through lymphatics and show enhanced cellular responses following immunization

Jeffrey Alan Hubbell, Melody Swartz, Sachiko Hirosue, Conlin O'Neil, Karen Dane, Jackson Eby

Poly(ethylene glycol)-stabilized poly(propylene sulfide) core (PEG-PPS) nanoparticles (NPs) smaller than 50 nm efficiently travel to draining lymph nodes and interact with antigen-presenting cells (APCs) to induce potent immune responses following intrader ...

Arginine-specific protein modification using alpha-oxo-aldehyde functional polymers prepared by atom transfer radical polymerization

Harm-Anton Klok, Maxime Ayer, Frederik Roman Wurm, Marc Gauthier, Justyna Kowal

The residue-specific modification of peptides and proteins is a powerful strategy for preparing biomolecular-synthetic polymer conjugates with advanced properties. This manuscript aims at expanding the present toolbox of residue-selective protein modificat ...

Photo-Fenton degradation of resorcinol mediated by catalysts based on iron species supported on polymers

César Pulgarin, Félicien Mazille

Novel Fe supported catalysts were prepared by immobilizing iron species on commercial polyethylene via three different methods: (1) acidic pre-treatment of the polyethylene followed by impregnation in aqueous Fe(NO3)(3), (2) TiO2 photo-catalytic pre-treatm ...

Improving the Stability in Aqueous Media of Polymer Brushes Grafted from Silicon Oxide Substrates by Surface-Initiated Atom Transfer Radical Polymerization

Harm-Anton Klok, Dusko Paripovic

Hydrophilic polymer brushes grown via surface-initiated ATRP from silicon oxide surfaces are susceptible to detachment via hydrolytic cleavage of the anchoring siloxane bond. This paper investigates the influence of the structure of the ATRP initiator on t ...

Polyimide foam-like microstructures: technology and mechanical properties

Philippe Renaud, Martinus Gijs, Sébastien Jiguet, Pierre Joris, Jagoda Anna Dobrzynska

We report a process for the realization of polyimide films with custom-designed microporosity based on the heat-induced depolymerization of polyimide-embedded polypropylene carbonate microstructures. The foam-like microstructures are up to 40 µm thick and ...

Influence of Residual Water and Carbon Containing Molecules in Focused Electron Beam Induced Processes

Bamdad Afra

Focused Electron Beam Induced Processing (FEBIP) is a technique used for etching and deposition of micro- and nano-structures using a focused electron beam. FEBIP is commonly carried out in a Scanning Electron Microscope (SEM) with a Gas Injection System ( ...
