The present study investigates the effect of tartaric acid on anodic film morphology and on corrosion resistance of hydrothermally sealed anodized AA2024. Anodizing treatment was performed in dilute sulfuric acid electrolyte with or without addition of tartaric acid. Hydrothermal sealing was carried out in boiling wat…
Nanoscaled and nanoporous ͑La 0.5 Sr 0.5 ͒CoO 3-␦ ͑LSC͒ thin film cathodes ͑film thickness ranging from 200 to 300 nm, grain and pore size in the range of 50 nm͒ were electrochemically characterized to determine their potential for intermediate and lowtemperature solid oxide fuel cells ͑SOFCs͒.Chemically homogeneous,…
Development of biomaterials with specific characteristics to influence cell behaviour has played an important role in exploiting strategies to promote nerve regeneration. The effect of three-dimensional (3D) non-woven electrospun poly(epsilon-caprolactone) (PCL) scaffolds on the behaviour of rat brain-derived neural s…
The application range of carbon nanotubes (CNTs) has been significantly expanded by the advent of reliable chemical functionalization methods. This article surveys electrochemistry-based approaches that have been devised for the covalent and non-covalent modification of CNTs, and highlights their increasing importance…
4 nm sized metallic magnesium particles were prepared by the sonoelectrochemical method.
Silica glasses containing both ZnS quantum dots (QDs) and luminescent lanthanide ions are attractive candidates to develop new lighting displays, sensor devices or laser emitters. This work reports an easy sol–gel method to prepare Eu3+-doped and Eu3+,Mn2+-codoped ZnS nanocrystals dispersed in a transparent silica mat…
Transparent heterogeneous ultrathin films of exfoliated layered double hydroxide (LDHs) nanosheets, fabricated alternately with polyanion, have been obtained via a layer-by-layer electrostatic self-assembly which yields a series of novel LDH films with potential multifunctionality.
Investigations of the micro‐ and nanostructures and chemical composition of the sponge skeletons as examples for natural structural biocomposites are of fundamental scientific relevance. Recently, we show that some demosponges ( Verongula gigantea, Aplysina sp.) and glass sponges ( Farrea occa, Euplectella aspergillum…
Surfaces obtained by modifying poly(N,N'-dimethylaminoethyl methacrylate) (PDMAEMA) on rough silicon substrates are highly hydrophilic at low pH and highly hydrophobic at high pH; such surfaces effectively supplement the research on the wettability of solid surfaces based on the pH-responsive polymers.
We report a simple and facile solid-state approach to large-scale synthesis of multiwalled carbon nanotubes (MCNTs), for the first time, by one-step direct thermolysis of a metal-organic framework [Ni(3)(btc)(2).12H(2)O] (btc = benzene-1,3,5-tricarboxylato) in a one-end closed conventional horizontal tube furnace unde…
Superhydrophobicity has recently drawn a great deal of attention from both fundamental and practical application points of view. This paper summarizes the basic principles involved in creation of superhydrophobicity and reviews the diverse methods recently developed to make superhydrophobic surfaces and coatings. The…
A sensor for the amperometric detection of aqueous ammonia was fabricated using the inkjet printing of dodecylbenzene sulfonate (DBSA)-doped polyaniline nanoparticles (nanoPANI) onto a screen-printed carbon paste electrode. The combination of the environmentally inert, aqueous nanoparticle dispersion with the inkjet p…
A new type of hierarchical structure, copper silicate hollow spheres assembled by nanotubes, was synthesized via a simple one-pot route by using silica colloidal spheres as chemical template.
Due to their extraordinary physical and chemical properties carbon nanotubes reveal promising potential as biomedical agents for heating, temperature sensoring and drug delivery on the cellular level. Filling carbon nanotubes with tailored materials realises nanoscaled containers in which the active content is encapsu…
The aim of this tutorial review is to give an overview of the state of the art of intracellular applications of analytical SERS spectroscopy. We pay particular attention to nanoparticle-based SERS spectroscopy since this currently dominates the published literature on non-disturbing analysis of live cells. We describe…
Liquid crystal containing composite fibres were produced via coaxial electrospinning, demonstrating that this technique can be used for producing new functional fibres and/or to study the impact of extreme confinement on liquid crystal phases.
A set of three pH-responsive ratiometric Eu(III)complexes has been synthesised incorporating a coordinated azathioxanthone sensitiser and a pH dependent alkylsulfonamide moiety. Emission properties, anion binding affinities, pH response curves and protein binding constants were studied in detail in aqueous media, and…
An aggregation-induced blue shift of emission was observed for the first time from a novel amphiphilic trifluorene, TFOH, and tentatively attributed to a similar TICT mechanism; the optical properties and self-assembly behaviors of TFOH, along with their relationships, are presented.
Well-defined nanostructural control from biological motifs is gaining attention among materials scientists. We are reporting that the β-sheet structure of L-polyalanine plays a critical role in developing a fibrous nanostructure as well as the sol-to-gel transition of amphiphilic poly(ethylene glycol)-L/or DL-polyalan…
The review focuses on the relationship between the structure and the glass transition temperature in polylactide and its derivatives. Simple design rules for controlling the glass transition temperature are developed and illustrated using examples from homopolymers, copolymers, and polymers derived from AB glycolide m…
