Professor Clare Grey (University of Cambridge, UK) has been elected as a fellow of the Royal Society in recognition of her pioneering research in using solid state NMR to study structure and function in inorganic materials. More details on the Royal Society website…
Professor Grey is also member of the Journal of Materials Chemistry advisory board. Here’s a reminder of some of the research Professor Grey has published in RSC journals:
On the outside cover is a paper on Electrochemistry-controlled metal ion release from silicone elastomer nanocomposites through combination of different metal nanoparticles by Anne Hahn, Sebastian Günther, Philipp Wagener and Stephan Barcikowski. In the paper the team report on the retardation and enhancement of metal ion release for time- and rate-controlled design of bioactive nanocomposites.
The Inside front cover highlights the work of Yonit Boguslavsky, Tania Fadida, Yossi Talyosef and Jean-Paul Lellouche and their paper on Controlling the wettability properties of polyester fibers using grafted functional nanomaterials. The paper describes a simple method for controlling the wettability properties of poly(ethyleneterephthalate) fibers. PET fibers were modified using silica nanoparticles to obtain a hydrophilic surface and multi-walled carbon nanotubes to create a hydrophobic surface.

Patterned fluorescence films with reversible thermal response based on the host–guest superarchitecture: A patterned fluorescence film that shows reversible thermal and fluorescent behaviour in the temperature range 20–130 °C has been created by a team at the Beijing University of Chemical Technology, China. The team say that the transformation of an organic chromophore from irreversible to reversible thermal response material upon incorporation into a 2D layered matrix is the most distinct feature in this work. Combining the patterning technique with the thermal responsive photoluminescence nature of the chromophore–layered double hydroxide composites could be applicable to the development of a wide selection of intelligent devices and display systems.

Tailoring hybrid glyco-nanolayers composed of chitohexaose and cellohexaose for cell culture applications: In this Hot Paper, Yuka Yoshiike and Takuya Kitaoka from Kyushu University, Japan, show that human carcinoma cells can adhere to self-assembled hybrid nanolayers of chitohexaose–thiosemicarbazide and cellohexaose–thiosemicarbazide. The surface density of bioactive chitohexaose is a key factor in cell adhesion efficiency, morphological variation and some cellular responses. Yoshiike and Kitaoka say that the Architectural design of carbohydrate-based hybrid nanolayers via the vectorial chain immobilization method is expected to provide a new concept for the functional development of glyco-decorated biointerfaces.

Superparamagnetic magnetite nanocrystal clusters as potential magnetic carriers for the delivery of platinum anticancer drugs: A magnetic drug carrier that can increase the cellular uptake of platinum drugs while maintaining the inherent cytotoxicity of the drug cargo has been developed by Chinese scientists. The drug carrier is based on superparamagnetic magnetite nanocrystal clusters modified by carboxymethylcellulose and is conjugated to the anit-cancer drug cisplatin. The advantages of this drug delivery system include the simplicity of preparation, multifunctionality of the particles, and high loading capacity of the carrier. The team led by Zijian Guo at Nanjing University, China, say that this approach may be further developed into a promising strategy for targeted delivery of other drugs or biofunctional molecules. (J.

Scientists in Singapore have prepared a coating for metals that heals itself after being scratched to prevent corrosion of the metal underneath.
Unlike other examples of such coatings, this one, developed by Mingxing Huang and Jinglei Yang of Nanyang Technological University, requires no catalyst and can be used at 40 degrees Celsius.
The team prepared the coating by encapsulating the highly reactive compound hexamethylene diisocyanate (HDI) inside polymer shells to form microcapsules. They then dispersed the microcapsules into epoxy resin and applied this coating to steel. When the coating was scratched, the punctured microcapsules released the HDI, which reacted with water to form polyurea and this sealed the damaged region… Read the rest of the article in Chemistry World or the paper by Mingxing Huang and Jinglei Yang here.
