Ammonia gas detection based on polyaniline nanofibers coated on interdigitated array electrodes

28-06-2010 | Zhifeng Du, Chengchao Li, Limiao Li, Hongchun Yu, Yanguo Wang, Taihong Wang, Journal of Materials Science: Materials in Electronics, 2010

Ammonia gas sensors were fabricated from polyaniline nanofibers, which were synthesized by a simple dilute polymerization method without external template. The films of polyaniline nanofibers were deposited on interdigitated array electrodes by drop casting method. The ammonia gas sensing ...

Synthesis and crystal structures of four mixed-ligand silver(I) complexes with sandwich-like structure

28-06-2010 | Chong-Chen Wang, Peng Wang, Guang-Sheng Guo, Transition Metal Chemistry, 2010

The reaction of AgNO3, with combinations of 4,4′-bipyridine (bpy), 1,2-di(4-pyridyl)ethylene (dpe), hexanedioic acid (HA), pyridine-3,5-dicarboxylic acid (pdc) and 3,3′4,4′-biphenyltetracarboxylic acid (bptc) in aqueous alcohol at room temperature produces block-like crystals of ...

Conformation and Fundamental Properties of Novel Lubricant TA-30 for Near Contact Magnetic Recording

28-06-2010 | Norio Tagawa, Hiroshi Tani, Tribology Letters, 2010

A novel perfluoropolyether (PFPE) lubricant called TA-30 has been developed recently. We investigate the conformation of TA-30 on diamond-like carbon (DLC) thin films, by attempting the direct observation of a lubricant film by atomic force microscopy (AFM) using a fluoride probe. We ...

Quantifying Pathways and Friction of Nanoparticles During Controlled Manipulation by Contact-Mode Atomic Force Microscopy

28-06-2010 | D. Dietzel, M. Feldmann, C. Herding, U. D. Schwarz, A. Schirmeisen, Tribology Letters, 2010

Measuring interfacial friction during the manipulation of nanoparticles is becoming an increasingly important approach in nanotribology research. In this work, antimony and gold particles deposited on flat graphite surfaces have been translated by the tip of an atomic force microscope in ...

Meso-macroporous Co3O4 electrode prepared by polystyrene spheres and carbowax templates for supercapacitors

28-06-2010 | Yanhua Li, Kelong Huang, Suqin Liu, Zufu Yao, Shuxin Zhuang, Journal of Solid State Electrochemistry, 2010

Meso-macroporous Co3O4 electrode is synthesized by drop coating with a mixed solution containing Co(OH)2 colloid, polystyrene spheres, and carbowax (namely polyethylene glycol), followed by calcining at 400 °C to remove polystyrene spheres and carbowax. For comparison, nonporous Co3O4 and ...

Self-assembly based on hydrotropic counterion—single-chain amphiphile ion pairs

28-06-2010 | Kadla R. Rosholm, Alfredo González-Pérez, Ole G. Mouritsen, Colloid & Polymer Science, 2010

We investigate the effect of organic hydrotropic counterions on the self-assembled structures formed by pure counterion—single-chain amphiphile ion pairs. The effect of inorganic counterions on single-chain amphiphiles has been studied for years, taking into account the Hofmeister series that ...

Easy detectable isocyanate in the reaction with gelatin

28-06-2010 | Monica Bertoldo, Federica Cognigni, Francesco Ciardelli, Polymer Bulletin, 2010

Gelatin reactivity with isocyanate was studied by using the easy detectable 1-naphthyl-isocyanate (NphI). Four different NphI/gelatin feed ratios were investigated with NphI molar amount ranging between 1/10 and 1/1 with respect to the possible reactive groups of gelatin. The reactions were ...

Integration of spore-based genetically engineered whole-cell sensing systems into portable centrifugal microfluidic platforms

28-06-2010 | Amol Date, Patrizia Pasini, Sylvia Daunert, Analytical and Bioanalytical Chemistry, 2010

Bacterial whole-cell biosensing systems provide important information about the bioavailable amount of target analytes. They are characterized by high sensitivity and specificity/selectivity along with rapid response times and amenability to miniaturization as well as high-throughput ...

Exploratory analysis of human urine by LC–ESI-TOF MS after high intake of olive oil: understanding the metabolism of polyphenols

28-06-2010 | Rocío García-Villalba, Alegría Carrasco-Pancorbo, Ekaterina Nevedomskaya, Oleg A. Mayboroda, André M. Deelder, Anton ..., Analytical and Bioanalytical Chemistry, 2010

Olive oil polyphenols have important biological properties which closely depend on their bioavailability; it is, therefore, essential to understand how polyphenols are absorbed, metabolized, and eliminated from the body. An analytical method based on rapid-resolution liquid chromatography ...
