The linear chromatic aberration (LCA) of several combinations of polycarbonates (PCs) and poly (methyl methacrylates) (PMMAs) as singlet, hybrid (refractive/diffractive) lenses and doublets operating with wavelengths between 380 and 1600 nm - corresponding to a typical zone of interest of concentrated photovoltaics (CPV) - are compared. Those comparisons show that the maximum theoretical concen...

A novel method was developed for the preparation of highly efficient anion- and cation-exchange microHPLC columns using an on-column polymerization of methacrylates having amine or sulfonic acid functional groups onto monolithic silica capillary columns modified with 3-methacryloxypropyltriethoxysilane as the anchor groups. The chromatographic evaluation of the columns using nucleic acids, nucl...

Isosorbide monomethacrylate (IMMA) is a biobased monomer that appears as potential substitute for current petrobased methacrylates to prepare high-performance sustainable polymers by free-radical polymerization technique. However, the molecular weight of can markedly affect their physical, mechanical and processing properties, it crucial understand nature processes control growing IMMA based po...

Crosslinked polymer samples of a wide range of triacrylates, tetraacrylates, pentaacrylates and of their corresponding methacrylates were prepared by u.v. photopolymerization of the monomers using 2,2dimethoxy-2-phenyl-acetophenone as a photoinitiator. The monomers studied varied in rank, pendant group size and structure, and functionality or number of double bonds. The reaction kinetics was fo...
