pH response and molecular recognition in a low molecular weight peptide hydrogel

16-12-2014 | Stefanie C. Lange; Jan Unsleber; Patrick Drücker; Hans-Joachim Galla; Mark P. Waller; Bart Jan Ravoo, Organic & Biomolecular Chemistry, 2014

In this article we report the preparation and characterization of a peptide-based hydrogel, which possesses characteristic rheological properties, is pH responsive and can be functionalized at its thiol function. The tripeptide N-(fluorenyl-9-methoxycarbonyl)-l-Cys(acetamidomethyl)-l-His-l-Cys-OH ...


Ternary polymer blends based on poly(lactic acid): Effect of stereo‐regularity and molecular weight

13-12-2014 | Sukunya Ross, Sararat Mahasaranon, Gareth M. Ross, Journal of Applied Polymer Science, 2014

ABSTRACT The effects of stereo‐regularity and molecular weight of poly(lactic acid) (PLA) on ternary polymer blends was analyzed using optical clarity as the primary screening method. This enabled the ready identification of phase boundaries of optically clear and apparently miscible regions. ...


Synthesis of self‐healing polyurethane urea‐based supramolecular materials

13-12-2014 | Young Joo Kim, Pil Ho Huh, Byung Kyu Kim, Journal of Polymer Science Part B: Polymer Physics, 2014

ABSTRACT Supramolecular polyurethane ureas are expected to have superior mechanical properties primarily due to the reversible, noncovalent interactions such as hydrogen bonding interactions. We synthesized polyurethane prepolymers from small molecular weight of poly(tetramethylene ...


Degradation of poly(vinyl alcohol)‐graft‐lactic acid copolymers by Trichotecium roseum fungus

12-12-2014 | Rodica Lipsa, Nita Tudorachi, Vasile Cristian Grigoraş, Cornelia Vasile, Journal of Applied Polymer Science, 2014

ABSTRACT The biodegradation of poly(vinyl alcohol) and poly(vinyl alcohol)‐graft‐lactic acid copolymers was analyzed, using Trichotecium roseum fungus. The samples were examined during biodegradation at different periods of exposure. Structural modifications of the biodegraded samples were ...


Study on physiochemical structure and in vitro release behaviors of doxycycline‐loaded PCL microspheres

12-12-2014 | Ozlem Aydin, Baran Aydin, Aysen Tezcaner, Dilek Keskin, Journal of Applied Polymer Science, 2014

ABSTRACT This study aimed to develop drug delivery system of doxycycline‐loaded polycaprolactone (PCL) microspheres. The investigated microsphere formulation can be considered for local application in bone infections and degenerative joint diseases, which generally require long‐term treatments ...


Well-Defined Block Copolymers with Triphenylamine and Isocyanate Moieties Synthesized via Living Anionic Polymerization for Polymer-Based Resistive Memory Applications: Effect of Morphological Structures on Nonvolatile Memory Performances

12-12-2014 | Beom-Goo Kang; Jingon Jang; Younggul Song; Myung-Jin Kim; Takhee Lee; Jae-Suk Lee, Macromolecules, 2014

The anionic block copolymerization of 4,4′-vinylphenyl-N,N-bis(4-tert-butylphenyl)benzenamine (A) with n-hexyl isocyanate (B) was performed using potassium naphthalenide (K-Naph) in THF at −78 and −98 °C in the presence of sodium tetraphenylborate (NaBPh4) to afford the well-defined block ...


Formation of Titanium Nanostructures on Block Copolymer Templates with Varying Molecular Weights

12-12-2014 | Martin Kreuzer; Claudia Simão; Ana Diaz; Clivia M. Sotomayor Torres, Macromolecules, 2014

A novel and simple method for producing mesoporous titanium films and supported titanium nanoparticle hexagonal arrays is presented. During evaporation on block copolymer templates, titanium self-assembles as either a mesoporous film or as a hexagonal close-packed nanodot structure. The ...


MALDI-TOF MS Imaging of Metabolites with a N-(1-Naphthyl) Ethylenediamine Dihydrochloride Matrix and Its Application to Colorectal Cancer Liver Metastasis

12-12-2014 | Jianing Wang; Shulan Qiu; Suming Chen; Caiqiao Xiong; Huihui Liu; Jiyun Wang; Ning Zhang; Jian Hou; Qing He; Zongxiu Nie, Analytical Chemistry, 2014

Matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI MSI) is a label-free technique for identifying multiplex metabolites and determining both their distribution and relative abundance in situ. Our previous study showed that N-(1-naphthyl) ethylenediamine dihydrochloride ...


Poly‐2‐[(4‐methylbenzylidene)amino]phenol: Investigation of thermal degradation and antimicrobial properties

11-12-2014 | Nuray Yılmaz Baran, Hacı Ökkeş Demir, Sedat Kostekçi, Mehmet Sacak, Journal of Applied Polymer Science, 2014

ABSTRACT A new polyphenol (poly‐2‐[(4‐methylbenzylidene)amino]phenol) (P(2‐MBAP)) containing an azomethine group was synthesized by oxidative polycondensation reaction of 2‐[(4‐methylbenzylidene)amino]phenol (2‐MBAP) with NaOCl, H2O2, and O2 oxidants in an aqueous alkaline medium. The ...


Capping of Aβ42 Oligomers by Small Molecule Inhibitors

11-12-2014 | Ziao Fu; Darryl Aucoin; Mahiuddin Ahmed; Martine Ziliox; William E. Van Nostrand; Steven O. Smith, Biochemistry, 2014

Aβ42 peptides associate into soluble oligomers and protofibrils in the process of forming the amyloid fibrils associated with Alzheimer’s disease. The oligomers have been reported to be more toxic to neurons than fibrils, and have been targeted by a wide range of small molecule and peptide ...
