A preliminary investigation of the fouling behaviour of smooth and roughened superhydrophobic coatings is reported. The effect of nanoscale interfacial roughness on the adhesion of single (SW8) and mixed cultures of micro-foulant for periods of up to 6 months was assessed using visual and wettability measurements. Det…
Biological organisms are able to direct the formation of patterned and hierarchical biomineral structures. Extractable organic materials have been found entrapped in diatom, sponge and plant biosilica, some of which have been isolated by selective chemical dissolution methods and their composition and structure studie…
In reduced dimensions, materials display characteristics quite different from their bulk behavior. Interestingly, most viruses, bacteria, pathogens, particles in gas phase and other chemical–biological agents, which form the basis of this investigation, also have comparable dimensions. Our present and ongoing investig…
A large-area network of polyaniline nanowires was potentiostatically deposited on a stainless steel electrode at the potential of and characterized in electrolyte for a redox supercapacitor. The specific capacitance of and specific power of was obtained at the charge-discharge current density of . A long charge-discha…
The intent of this tutorial review is to cover the recent progress accomplished in iron and manganese porphyrin-catalyzed enantioselective epoxidation of terminal olefins. The literature is covered up to the beginning of 2005. In the first part of the manuscript, we will present the results obtained with simple cataly…
The design and formation of a linear assembly of gold nanorods using a biomolecular recognition system are described. Anti-mouse IgG was immobilized on the {111} end faces of gold nanorods through a thioctic acid containing a terminal carboxyl group. The biofunctionalized nanorods can be assembled with the desired len…
Diarylethenes undergo thermally irreversible and fatigue-resistant photochromic reactions not only in solution but also in the single-crystalline phase. This article describes recent development of the single-crystalline photochromism of diarylethene derivatives. We focused on the relationship between their crystal st…
This “Applications” article focuses on superquenching of the fluorescence of conjugated polyelectrolytes and related fluorescent polyelectrolytes and its applications to biosensing. Superquenching can occur for both aqueous solutions of these polymers as well as for various supported formats. For biosensing the suppor…
Abstract Several workers from various institutions in six countries have prepared thin films and colloidal polyaniline dispersions. The films were produced in situ on glass supports during the oxidation of anilinium chloride with ammonium peroxydisulfate in water. The average thickness of the films, assessed by optica…

Soil organic matter (SOM) is a fundamental component of soil and the global C cycle. We used C (1s) near‐edge x‐ray absorption fine structure (NEXAFS) and synchrotron‐based Fourier transform infrared‐attenuated total reflectance (FTIR‐ATR) spectroscopy to speciate C and investigate the influence of land use on the com…
Carbon nanotubes (CNT) have unique mechanical properties that make them close to ideal reinforcing materials. Single walled CNT have a modulus of elasticity of approximately 1 TPa, yield strengths measured at between 20 and 60 GPa, and measured elastic strains at yield that are greater than 10%. In addition, CNT typic…
We report near infrared broadband emission of bismuth-doped barium-aluminum-borate glasses. The broadband emission covers 1.3microm window in optical telecommunication systems. And it possesses wide full width at half maximum (FWHM) of ~200nm and long lifetime as long as 350micros. The luminescent properties are quite…
Bio-nanocomposites are an emerging group of hybrid materials derived from natural polymers and inorganic solids interacting at the nanometric scale. These nanostructured organic–inorganic materials could be designed and prepared using a wide type of biopolymers and also inorganic solids with different compositions and…
To protect solid oxide fuel cells (SOFCs) from chromium poisoning and improve metallic interconnect stability, manganese cobaltite spinel protection layers with a nominal composition of Mn 1 . 5 Co 1 . 5 O 4 were thermally grown on Crofer22 APU, a ferritic stainless steel. Thermal, electrical, and electrochemical inve…
Polycrystalline aggregates are comprised of three microstructural features: grain centers, grain boundaries, and regions affected by grain boundaries. It is these features that determine the mechanical properties, and any advanced understanding of microstructure-property relations requires their quantitative descripti…
Ni(OH)2 hollow microspheres with beta-Ni(OH)2 nanosheets as the in situ formed building units were fabricated via a novel template-free approach in a strong alkaline solution of glycine, and can be converted into NiO hollow microspheres by a thermal decomposition process.
Well-ordered mesoporous alumina materials with high surface area and a narrow pore size distribution were synthesized using a sol-gel based self assembly technique.
Sol–gel derived hybrid organic–inorganic materials present several advantages to the design of materials for optical applications: they have versatile and relatively facile chemistry; are easy to shape and pattern, and they have good mechanical and excellent optical properties. Their nanocomposite structure gives oppo…
The shape of gold nanoparticles has been successfully tuned among penta-twinned decahedrons, truncated tetrahedrons, cubes, octahedrons, hexagonal thin plates by introducing a small amount of salt into a N,N-dimethylformamide (DMF) solution containing poly(vinyl pyrrolidone) (PVP), and changing the temperature or the…
