Surface plasmon enhanced Förster resonant energy transfer (FRET) between CdTe nanocrystal quantum dots (QDs) has been observed in a multilayer acceptor QD-gold nanoparticle-donor QD sandwich structure. Compared to a donor-acceptor QD bilayer structure without gold nanoparticles, the FRET rate is enhanced by a factor o…
We report that defect-free Au nanowires show superplasticity on tensile deformation. Evidences from high-resolution electron microscopes indicated that the plastic deformation proceeds layer-by-layer in an atomically coherent fashion to a long distance. Furthermore, the stress-strain curve provides full interpretation…
The increasing importance of nanotechnology in the biomedical field and the recent progress of nanomedicines into clinical testing have spurred the development of even more sophisticated nanoscale drug carriers. Current nanocarriers can successfully target cells, release their cargo in response to stimuli, and selecti…
Recent investigations on the tensile properties of natural cellulose-based fibers revealed an increasing potential as engineering materials. This is particularly the case of very thin fibers of some species such as sisal, ramie, and curaua. However, several other commonly used fibers such as flax, jute, hemp, coir, co…
Chemically modified graphene has been studied in many applications due to its excellent electrical, mechanical, and thermal properties. Among the chemically modified graphenes, reduced graphene oxide is the most important for its structure and properties, which are similar to pristine graphene. Here, we introduce an e…
Abstract Concentrated colloidal suspensions are a well‐tested model system which has a glass transition. Colloids are suspensions of small solid particles in a liquid, and exhibit glassy behaviour when the particle concentration is high; the particles are roughly analogous to individual molecules in a traditional glas…
Abstract Most of the solid materials we use in everyday life, from plastics to cosmetic gels exist in a non-crystalline, amorphous form: they are glasses. Yet, we are still seeking a fundamental explanation as to what glasses really are, why they form, and what their properties are. This book surveys the most recent t…
Abstract Physical properties of graphene depend on the number of atomic layers in the film, presence of structural defects and impurities. Low‐voltage, aberration‐corrected, high‐resolution transmission electron microscopy (HRTEM) has proven to be an excellent tool for structure analysis of graphene films. However, ex…
Abstract A combined electroless plating and sol–gel method was developed for preparing a NiP/TiO 2 bilayer coating to achieve an especial photocathodic protection effect for A3 low carbon steel. Photocathodic protection properties of the coating were investigated by the electrochemical method. Surface morphology and s…
Abstract This paper outlines how a corrosion map of zinc was developed for Abu‐Dhabi. It presents inputs into the model being databases of RH, rainfall, salt deposition and time of wetness and explains how these inputs are combined to product the corrosion map of Abu Dhabi. It is found that although the corrosion rate…
Single chain block copolymers in poor solvents with asymmetric A and B species block lengths form an interesting and potentially useful set of conformations not yet fully investigated by the literature. Self-consistent field theory simulations performed in this work predict that the chains collapse to form a sphere of…
Abstract The inhibition effect of 1‐(4‐(dimethylamino)benzylidene)thiosemicarbazide (DBT) on the corrosion behavior of 304 stainless steel and mild steel in 0.5 M sulfuric acid solution was investigated using weight loss and potentiostatic polarization methods. The experimental results suggest that DBT inhibits the co…
Abstract The weld used to connect two different metals is known as a dissimilar metal weld (DMW). In nuclear power plants, this weld is used to join stainless steel to low-alloy steel components in the nuclear pressurized water reactor (PWR). The most common weld metal is Alloy 182 (UNS W86182). Originally selected fo…
We address a central issue of phononics: the search of properties or mechanisms to manage the heat flow in reliable materials. We analytically study standard and simple systems modeling the heat flow in solids, namely, the harmonic, self-consistent harmonic and also anharmonic chains of oscillators, and we show an int…
An isochorismate-pyruvate lyase with adventitious chorismate mutase activity from Pseudomonas aerugionsa (PchB) achieves catalysis of both pericyclic reactions in part by the stabilization of reactive conformations and in part by electrostatic transition-state stabilization. When the active site loop Lys42 is mutated…
There has been tremendous recent progress in realizing topological insulator initiated by the proposal of Kane and Mele for the graphene system. They have suggested that the odd ${Z}_{2}$ index for the graphene manifests the spin-filtered edge states for the graphene nanoribbons, which lead to the quantum spin Hall ef…
Eutectic materials have potential as photoactive materials, due to their multiphase character (various available photoactive component phases and multiple band gap energies) and high crystallinity. However, larger material samples are needed to demonstrate it. In order to overcome this limitation, the growth of a plat…
Carbon-encapsulated iron nanoparticles were synthesized by pyrolysis at 1000 °C of two solid precursors: poly(vinyl alcohol) and iron citrate. The weight ratio between the precursors controlled the reaction yield, crystallinity, morphological features and magnetic properties of the products. The encapsulation yield of…
The upper critical field was measured up to 12 T for three BaFe${}_{2\ensuremath{-}\mathrm{x}}$Co${}_{\mathrm{x}}$As${}_{2}$ single crystals with estimated Co concentrations of $x$ $=$ 0.082, $x$ $=$ 0.117, and $x$ $=$ 0.143. ${H}_{\mathrm{C}2}$ versus temperature was measured from temperature-dependent resistivity fo…
The numerical analysis of a new model of metal crystallization is performed. The novelty of the model, which has recently appeared in publications, consists in modeling that is simultaneously carried out at several scale levels, from micro-to macroscales. Although experimental studies of metal crystallization revealed…
