Determination of Nanoscale Mechanical Properties of Polymers via Plasmonic Nanoantennas
(American Chemical Society, 2020-06)
Nanotechnology and the consequent emergence of miniaturized devices are driving the need to improve our understanding of the mechanical properties of a myriad of materials. Here we focus on amorphous polymeric materials ...
Free Radical Polymerization: Heterogeneous Systems
(Wiley Blackwell Publishing, Inc, 2007)
Bulk free-radical polymerizations are carried out in the absence of a dispersion medium, and without (or with a very little) solvent. Many technical polymers such as LDPE, LLDPE, PVC, PS, HIPS, PMMA, nylon, and polyester ...
Model Block Copolymers: Synthesis, Properties and Morphological Characterization
(Nova Science Publishers, 2014)
Block copolymers constitute a fascinating group of polymeric materials belonging to the "soft matter" family. These materials are formed by blocks of polymeric chains from different monomers. In most cases, these blocks ...
Exact solution of the hydrodynamic focusing driven by hydrostatic pressure
(Springer Heidelberg, 2020-02)
Microfluidic nanoprecipitation makes use of hydrodynamic focusing (HF) to accurately control the diffusive mixing of reactants. Both stability and precise handling of flow streams are essential for this application. However, ...
Picosecond laser interference patterning of periodical micro architectures on metallic molds for hot embossing
(Multidisciplinary Digital Publishing Institute, 2019-10-18)
In this work, it is demonstrated that direct laser interference patterning (DLIP) is a method capable of producing microtextured metallic molds for hot embossing processes. Three different metals (Cr, Ni, and Cu), relevant ...
Polymeric matrices based on graft copolymers of PCL onto acrylic backbones for releasing antitumoral drugs
(Wiley-liss, Div John Wiley & Sons Inc, 2003-03-07)
Graft copolymers of poly(ϵ‐caprolactone) (PCL) on poly(dimethylacrylamide) (PDMAm), poly(methylmethacrylate) (PMMA), or on copolymers of poly(DMAm‐co‐MMA) have been synthesized and characterized by 1H NMR spectroscopy, ...
From spherical micelles to hexagonally packed cylinders: the cure cycle determines nanostructures generated in block copolymer/ epoxy blends
(American Chemical Society, 2013-06-04)
Block copolymer (BCP)/epoxy blends have been intensively investigated during the past decade. Macrophase separation of the BCP in the cured thermoset is avoided by selecting one block that is initially immiscible or that ...
Microfluidic-free encapsulation of bacteria for isothermal DNA amplification
(Universidad Nacional de Córdoba, 2019)
Linking genotype (a nucleic acid that can be replicated) and phenotype (a functional trait, such as a binding or catalytic or regulatory activity) in a unique compartment is a key aspect of protein functional analysis, ...
Gravity driven flow for the precise control of hydrodynamic focusing
(Universidad Nacional de Córdoba, 2019)
Hydrodynamic focusing is a key operation in microfluidics, withapplications that range from cell sorting and counting to mixing and reactions.For most of these operations, both stability and precise handling of thefocused ...
Control of morphologies and mechanical properties of thermoplastic-modified epoxy matrices by addition of a second thermoplastic
(John Wiley & Sons Ltd, 2003-09)
Ternary mixtures based on stoichiometric mixtures of the diglycidyl ether of bisphenol-A (DGEBA) and 4,4′-diaminodiphenyl sulfone (DDS) and two miscible thermoplastics, poly(methyl methacrylate) (PMMA) and the poly(hydroxy ...
