Materials, Vol. 6, Pages 3826-3839: Dopamine-Mediated Sclerotization of Regenerated Chitin in Ionic Liquid

06-Sep-2013 | Oh, Dongyeop X.; Shin, Sara ; Lim, Chanoong ; Hwang, Dong Soo, Materials, 2013

Chitin is a promising structural material for biomedical applications, due to its many advantageous properties and abundance in nature. However, its usage and development in the biomedical field have been stagnant, because of chitin’s poor mechanical properties in wet conditions and the ...

In Situ Grazing Incidence Small-Angle X-ray Scattering Investigation of Polystyrene Nanoparticle Spray Deposition onto Silicon

29-Aug-2013 | Gerd Herzog; Gunthard Benecke; Adeline Buffet; Berit Heidmann; Jan Perlich; Johannes F. H. Risch; Gonzalo Santoro; M ..., Langmuir, 2013

We investigated the spray deposition and subsequent self-assembly during drying of a polystyrene nanoparticle dispersion with in situ grazing incidence small-angle X-ray scattering at high time resolution. During the fast deposition of the dispersion and the subsequent evaporation of the solvent, ...

Preserving Precision of Inkjet-Printed Features with Solvents of Different Volatilities

26-Aug-2013 | Jeng-Lung Lin; Zhen-Kai Kao; Ying-Chih Liao, Langmuir, 2013

For printed micropatterns on plastic substrates, the decreasing volume because of solvent evaporation frequently leads to contact line receding and changes the original printed pattern. To prevent printing quality deterioration caused by contact line motions, an ink formulation method was ...

Biodegradable Mesostructured Polymer Membranes

21-Aug-2013 | Bozhi Tian; Sahadev A. Shankarappa; Homer H. Chang; Rong Tong; Daniel S. Kohane, Nano Letters, 2013

The extracellular matrix (ECM) has a quasi-ordered reticular mesostructure with feature sizes on the order of tenths of to a few hundred nanometers. Approaches to preparing biodegradable synthetic scaffolds for engineered tissues that have the critical mesostructure to mimic ECM are few. Here we ...

Temporal Evolution of Optical Gradients during Drying in Cast Polymer Solutions

19-Aug-2013 | Orcun Yucel; Emre Unsal; M. Cakmak, Macromolecules, 2013

The development of optical anisotropy gradient as a result of solvent evaporation for poly(amide–imide) (PAI) solution in dimethylacetamide (DMAc) was investigated for the first time. Experiments were carried out using real-time optical measurement with spectral birefringence technique coupled ...

Long‐range‐ordered, hexagonally packed nanoporous membranes from degradable‐block‐containing diblock copolymer film templates

12-Aug-2013 | Lei Lei, Yuzheng Xia, Xiaonong Chen, Shuxian Shi, Journal of Applied Polymer Science, 2013

ABSTRACT Polystyrene (PS)‐b‐polylactide (PLA) diblock copolymers with different molecular weights and fractions were synthesized through a combination of living anionic polymerization and controlled ring‐opening polymerization. Then, the PS–PLA films were guided to phase‐separate by ...

Fabrication of polymeric nanoparticles of poly(ethylene‐co‐vinyl acetate) coated with chitosan for pulmonary delivery of carvedilol

07-Aug-2013 | Jaleh Varshosaz, Somaih Taymouri, Hamed Hamishehkar, Journal of Applied Polymer Science, 2013

ABSTRACT Carvedilol is a drug with low oral bioavailability due to its high first‐pass metabolism. The purpose of the present study was to prepare a mucoadhesive dry powder inhaler of this drug loaded in poly(ethylene‐co‐vinyl acetate)(PEVA) nanoparticles for pulmonary delivery. PEVA ...

Dynamic Changes in Structural Color of a Lamellar Block Copolymer Photonic Gel during Solvent Evaporation

06-Aug-2013 | Wonmok Lee; Jongseung Yoon; Edwin L. Thomas; Hyunjung Lee, Macromolecules, 2013

A high molecular weight, lamellar block copolymer (BCP) can exhibit a photonic stop band in the visible range of wavelengths due to the one-dimensional periodic dielectric layer structure. After dissolving a high molecular weight BCP in a neutral solvent, solvent evaporation causes microphase ...
