Imidazole-containing triblock copolymers with a synergy of ether and imidazolium sites
(The Royal Society of Chemistry, 2015-03-06)Reversible addition-fragmentation chain transfer (RAFT) polymerization enabled the synthesis of well-defined A-BC-A triblock copolymers containing a synergy of pendant ether and imidazolium sites. The soft central BC block ... -
Imparting functional variety to cellulose ethers via olefin cross-metathesis
(The Royal Society of Chemistry, 2015-04-09)Olefin cross-metathesis is a valuable new approach for imparting functional variety to cellulose ethers. Starting from commercially available ethyl cellulose, terminally unsaturated alkyl groups were appended as metathesis ... -
Peptide-based hydrogen sulphide-releasing gels
(The Royal Society of Chemistry, 2015-07-20)An aromatic peptide amphiphile was designed for delivery of the signaling gas H2S. The peptide self-assembled in water into nanofibers that gelled upon charge screening. The non-toxic gel slowly released H2S over 15 hours, ... -
Size dependent ion-exchange of large mixed-metal complexes into Nafion® membranes
(The Royal Society of Chemistry, 2015-08-18)Perfluorosulfonate ionomers have been shown to demonstrate a profound affinity for large cationic complexes, and the exchange of these ions may be used to provide insight regarding Nafion® morphology by contrasting molecular ... -
Phosphonium-containing diblock copolymers from living anionic polymerization of 4-diphenylphosphino styrene
(The Royal Society of Chemistry, 2015-11-20)Living anionic polymerization of 4-diphenylphosphino styrene (DPPS) achieved well-defined homopolymers, poly(DPPS-b-S) styrenic block copolymers, and poly(I-b-DPPS) diene-based diblock copolymers with predictable molecular ... -
Elucidating the Potential Biological Impact of Cellulose Nanocrystals
(MDPI, 2016-07-08)Cellulose nanocrystals exhibit an interesting combination of mechanical properties and physical characteristics, which make them potentially useful for a wide range of consumer applications. However, as the usage of these ... -
3D printing vending machine
(United States Patent and Trademark Office, 2016-08-16)A vending machine for creating a three-dimensional object having an enclosure having an exterior and interior. The interior receives and houses at least one three-dimensional printer. An interface for accepting an instruction ... -
Remote Actuation of Magnetic Nanoparticles For Cancer Cell Selective Treatment Through Cytoskeletal Disruption
(Springer Nature, 2016-09-20)Motion of micron and sub-micron size magnetic particles in alternating magnetic fields can activate mechanosensitive cellular functions or physically destruct cancer cells. However, such effects are usually observed with ... -
A critical review of the current knowledge regarding the biological impact of nanocellulose
(2016-12-01)Several forms of nanocellulose, notably cellulose nanocrystals and nanofibrillated cellulose, exhibit attractive property matrices and are potentially useful for a large number of industrial applications. These include the ... -
