Observation of a Charmoniumlike Enhancement in the γγ→ωJ/ψ Process

Olivier Schneider, Chao Wang, Tagir Aushev, Remi Léandre Albert Louvot, Ji Hyun Kim, Jing Li

We report the results of a search for a charmoniumlike state produced in the process gamma gamma -> omega J/psi in the 3.9-4.2 GeV = c(2) mass region. We observe a significant enhancement, which is well described by a resonant shape with mass M = (3915 +/- ...

Control of morphology and nanostructure of copper and cobalt oxalates: Effect of complexing ions, polymeric additives and molecular weight

Heinrich Hofmann, Paul Bowen, Jacques Lemaître, Alke Fink, Nathalie Jongen

Precipitated oxalates are often nanostructured and can be used as precursors for nanostructured oxides for different applications. The modification of the particle shape and nanostructures of both copper and cobalt oxalates has been demonstrated using poly ...

"Functional Poly(ethylene glycol)": PEG-Based Random Copolymers with 1,2-Diol Side Chains and Terminal Amino Functionality

Frederik Roman Wurm

A series of poly(ethylene glycol-co-isopropylidene glyceryl glycidyl ether) (P(EO-co-IGG)) random copolymers with different fractions of 1,2-isopropylidene glyceryl glycidyl ether (IGG) units was synthesized. After acidic hydrolysis a new type of "function ...

An ultrasensitive vibrating channel mass sensor based on tunnelling current detection

Maurizio Migliore

We present a new design of a mass sensor capable of detecting mass values in the zeptogram range. The sensor comprises a resonant beam and two gate electrodes used to oscillate the beam at its resonance frequency. The detection method is based on the tunne ...

Strategies to prolong the plasma residence time of peptide drugs

Christian Heinis, Lisa Pollaro

Peptides are an attractive class of molecules for the development of therapeutics because they combine unique properties such as high binding affinity, excellent target specificity, low toxicity and a relatively small mass. However, the short in vivo half- ...
