Soft Matter Lectureship Award winner announced

We would like to congratulate Professor Michael J. Solomon, winner of the 2011 Soft Matter Lectureship, an annual award to honour a younger scientist who has made a significant contribution to the soft matter field.

Michael J. Solomon is Professor of Chemical Engineering at the University of Michigan Ann Arbor.  Solomon’s research addresses questions about the structure and function of soft matter.  His group has developed methods in confocal microscopy to understand how colloids, anisotropic particles and bacteria biofilms assemble into structures such as gels and crystals, and how these structures respond to forces due to shear flow, centrifugation and electric fields.

As the award winner, Professor Solomon will be presenting lectures at three up-coming conferences to be confirmed shortly.

Hot Articles: Temperature sensitive triblocks and Double-hydrophilic Diblocks plus Synthetic surgical sealants

Follow the links below to read these papers for FREE until July 17….

triblock copolymerTriblock copolymers: Temperature-sensitive polymer aqueous solutions showing sol-to-gel transition with temperature increase have drug delivery, tissue engineering and post-operative applications. Sequence control of the triblock copolymers studied here was observed to influence the different transitions from alpha-helix to random coils, cylindrical bundles or spherical micelles at different temperatures. Soo Hyun Park, Bo Gyu Choi, Hyo Jung Moon, So-Hye Cho and Byeongmoon Jeong, Soft Matter, 2011, DOI: 10.1039/C1SM05505D.

Double-hydrophilic block copolymers: The formed diblock copolymers undergo unusual aqueous (micro)phase separation of binary mixtures of two biocompatible hydrophilic homopolymers. This is one of the few reports on block copolymer self-assembly in aqueous solution. Adam Blanazs, Nicholas J. Warren, Andrew L. Lewis, Steven P. Armes and Anthony J. Ryan, Soft Matter, 2011, DOI: 10.1039/C1SM05771E.

surgical sealantSoft tissue sealants: A new family of copolymers were derived from poly(glycerol sebacate) and lactic acid and when used in surgical sealants exhibited significantly higher adhesive strengths than fibrin sealants or synthetic PleuraSeal(TM) for wound dressing. The materials also had improved cytocompatibility. Qizhi Chen, Shuling Liang and George A. Thouas, Soft Matter, 2011, DOI: 10.1039/C1SM05350G.

Soft Matter makes the news!

Gel fixes back problemsSoft Matter article on a gel that can fix back aches has been reported in the Daily Mail and the Telegraph. The work by Dr Brian Saunders and Professor Tony Freemont at the University of Manchester, involves the injection of a  liquid containing microgel particles into the spine where the sponge-like particles expand to form a strong, load-bearing material.

Hot Articles: Microorigami–drug nanocarriers–porous media

 

microorigamiRead these Hot Articles for free until 8 July…

Tutorial review on soft microorigami: Polymer films which are able to fold and form 3D microstructures are important for optical materials, tissue engineering scaffolds and electronic devices. This review focuses on polymer-based systems and their fabrication, design and applicability for biotechnology. Leonid Ionov, Soft Matter, 2011, DOI: 10.1039/C1SM05476G

Nanocapsules for sustained drug release: The fabricated stable drug delivery systems for podrug nanocarriersorly water-soluble drugs exhibited a narrow size distribution, which makes them potential candidates for nanocarriers in cancer therapy. Surfactant structure was compared with nanocapsule stability and the number of polyelectrolyte layers required to create exetremely long-term sustained release of active molecules determined. Urszula Bazylińska, Renata Skrzela, Krzysztof Szczepanowicz, Piotr Warszyński and Kazimiera A. Wilk, Soft Matter, 2011, DOI: 10.1039/C1SM05395G

Improved mechanical properties for macroporous polymers: Highly permeable macroporous polymers were synthesised from a Pickering-MIPE template. The mechanical properties were much improved compared to porous media synthesised using conventional high internal phase emulsion (HIPE) templates. Vivian O. Ikem, Angelika Menner and Alexander Bismarck, Soft Matter, 2011, DOI: 10.1039/C1SM05272A

Soft Matter article highlighted in ChemistryWorld

Ionic liquid advance over saline-based lenses

Ionic liquids are the key to observing improved performance and wider temperature ranges for variable focus lenses over conventional saline alternatives, report scientists in China.

Electrowetting-based variable focus liquid lenses (EVFLL) have been used in mobile phones, barcode readers and other optical equipment, in which the conductive liquid inside the lenses is currently limited to saline. In applications such as these, saline can only work in a narrow temperature range as it may evaporate or freeze in extreme temperatures. The lenses also need to operate in a wide spectral range, but again saline is restrictive here as it becomes opaque in the near infrared region – not ideal for optical devices… Read the rest of the article here…

Hot articles: Gel swelling, viscous drag friction and microdomain orientation…

Read these Hot Articles for free until June 24:

viscous drag frictionFernandez-Nieves and co-workers describe the use of hydrostatic pressure to change the size and structure of poly-(N-isopropylacrylamide) based microgel particles. These changes rely on changes in the miscibility of the polymer in the solvent. Pressure was found to play an analogous role to temperature in swelling of the gels. Juan José Liétor-Santos, Benjamín Sierra-Martín, Urs Gasser and Alberto Fernández-Nieves, Soft Matter, 2011, DOI: 10.1039/C1SM05328K

viscous drag frictionThe viscous drag friction acting on fluid drops in confined geometries is a fundamental issue when dealing with small amounts of liquid. Researchers have established unexpectedly simple scaling laws for viscous drag friction in different regimes, replacing the well-known Stokes’ friction law. Ayako Eri and Ko Okumura, Soft Matter, 2011, DOI: 10.1039/C0SM01535K

 

block copolymer thin filmSupramolecular assembly is demonstrated to efficiently control the microdomain orientation in block copolymer thin films. The effect of low-molecular-weight additives on the microdomain orientation was investigated. At low grafting density the microdomains are parallel to the surface, while above a critical grafting density they switch to perpendicular.  Chih-Hung Lee and Shih-Huang Tung, Soft Matter, 2011, DOI: 10.1039/C1SM05334E

Hot Articles: magnetic flux lines, crystal nucleation and interfacial investigations….

Read these Hot Articles for free until June 22:

Magnetic flux lines

Magnetic flux lines were accurately modelled and mapped out in a new study on the effect of applied external fields to magnetic nanoparticle assembly. Ferrimagnetic iron oxide particles were used in the fossilized liquid assembly method, and agglomeration and sedimentation of the magnetic nanoparticles were also investigated . Ryan Schmidt, Jason Benkoski, Kevin Cavicchi and Alamgir Karim, Soft Matter, 2011, DOI: 10.1039/C1SM05057E

NucleationQuestions regarding heterogeneous nucleation in colloidal model systems are answered in this recent study. Although classical theories exist for crystal growth, the actual experimental determination of this process is still a challenge. Heterogeneous and homogeneous nucleation rate densities were both determined and compared. Andreas Engelbrecht, Rafaella Meneses and Hans Joachim Schöpe, Soft Matter, 2011, Advance Article, DOI: 10.1039/C1SM05246B

surfactantNew investigations into interfacial properties of surfactant-decorated particles in interfacial layers have been performed. Nanometric dispersions of colloidal silica nanoparticles with a cationic surfactant, CTAB were studied, and surfactant rheology was studied on a broad frequency window for the first time. L. Liggieri, E. Santini, E. Guzmán, A. Maestro and F. Ravera, Soft Matter, 2011, Advance Article, DOI: 10.1039/C1SM05257H
