Materials Chemistry - Researchers from University of Trieste publish new studies and findings in the area of materials chemistry
2010 MAR 15 - (VerticalNews.com) -- "Anisotropic nanoparticles with precisely controlled chemical functionality are attractive building blocks for the assembly of sophisticated new materials and devices," scientists in Trieste, Italy report. "Metal nanoparticles protected by self-assembled organic monolayers (MPCs) have drawn increasing attention due to potential applications in biosensing, catalysis, electronics and nanotechnology. However, a significant challenge remaining in nanoscience research is the capability to break symmetry in the isotropic ligand shell passivating these metal particles," wrote C. Gentilini and colleagues, University of Trieste ...read more
Materials Chemistry - Reports outline materials chemistry study results from M. Murakami et al
2010 MAR 15 - (VerticalNews.com) -- "A variety of supramolecular complexes were formed by associating an electron donor-substituted flavin dyad (10-[4'-(N,N-dimethylamino)phenyl]isoalloxazine: DMA-Fl) and a family of fullerene derivatives that contain single and double hydrogen bond receptors (SRC60 and DRC60). The stoichiometry of the corresponding complexes, that is, DMA-Fl and SRC60 or DRC60, were examined by Job's plot analysis of the absorption changes linked to DMA-Fl at 470 nm," scientists in Erlangen, Germany report ...read more
Materials Chemistry - Research on materials chemistry published by scientists at University of Jena
2010 MAR 15 - (VerticalNews.com) -- According to recent research published in the Journal of Materials Chemistry, "This article describes the synthesis and characterisation of poly(acrylamide) nanoparticles (NPs) with a covalently immobilised pH-sensitive fluorophore." "With a pK(a) of 6.7, good photostability, emission in the visible spectral range and large Stokes' shift the naphthalimide-based pH-indicator is well suited for bio-analytical applications. Additionally, the nanosensors contain a pH-insensitive reference fluorophore that allows the ratiometric monitoring of pH e.g. inside living cells," wrote A. Schulz and colleagues, University of Jena ...read more
