Single-crystalline photochromism of diarylethenes: reactivity–structure relationship
Photochromic reactivity of diarylethenes in the single-crystalline phase was found to be controlled by the distance between the reactive carbon atoms in the antiparallel conformation.
Density changes upon crystallization of Ge2Sb2.04Te4.74 films
The density of sputtered Ge2Sb2.04Te4.74 thin films upon annealing has been precisely determined by x-ray reflection and compared to the values determined from x-ray diffraction (XRD) data. The film density increases in two steps around 130 and 280 °C upon annealing up to 400 °C. These increases are consequences of ph…
Architectural Control of Magnetic Semiconductor Nanocrystals
Shape- and dopant-controlled magnetic semiconductor nanocrystals have been achieved by the thermolysis of nonpyrophoric and less reactive single molecular precursors under a monosurfactant system. Reaction parameters governing both the intrinsic crystalline phase and the growth regime (kinetic vs thermodynamic) are fo…
An experimental study of the kinetics of decompression‐induced crystallization in silicic melt
Experiments were conducted to study the temporal evolution of feldspar crystallization kinetics during isothermal decompression. Pinatubo dacite was held at 780°C, 220 MPa, f O2 = NNO + 2, H 2 O‐saturated conditions for an equilibration period, decompressed to final pressures, P f , ranging from 175 to 5 MPa, and then…
Synthesis of Polymer Brushes on Silicate Substrates via Reversible Addition Fragmentation Chain Transfer Technique
Reversible addition fragmentation chain transfer (RAFT) has been used to synthesize polymer brushes. Styrene, methyl methacrylate, and N, N -dimethylacrylamide brushes were prepared under RAFT conditions using silicate surfaces that were modified with surface-immobilized azo initiators. Films with controlled thickness…
The final stage of the collapse of a cavitation bubble close to a rigid boundary
The final stage of the collapse of a laser-produced cavitation bubble close to a rigid boundary is studied both experimentally and theoretically. The temporal evolution of the liquid jet developed during bubble collapse, shock wave emission and the behavior of the “splash” effect are investigated by using high-speed p…
MICROSTRUCTURAL EVOLUTION IN POLYMER BLENDS
▪ Abstract Microstructure in an immiscible polymer blend consists of the size, shape, and orientation of the phases. Blends exhibit many interesting behaviors, including enhanced elasticity at small strains, drop-size hysteresis, enhanced shear thinning, and stress relaxation curves whose shapes are sensitive to defor…
Geno3D: automatic comparative molecular modelling of protein
Abstract Geno3D (http://geno3d-pbil.ibcp.fr) is an automatic web server for protein molecular modelling. Starting with a query protein sequence, the server performs the homology modelling in six successive steps: (i) identify homologous proteins with known 3D structures by using PSI-BLAST; (ii) provide the user all po…
Enzyme‐Carrying Polymeric Nanofibers Prepared via Electrospinning for Use as Unique Biocatalysts
Improvement of catalytic efficiency of immobilized enzymes via materials engineering was demonstrated through the preparation of bioactive nanofibers. Bioactive polystyrene (PS) nanofibers with a typical diameter of 120 nm were prepared and examined for catalytic efficiency for biotransformations. The nanofibers were…
Synthesis of a Novel, Biodegradable Electrically Conducting Polymer for Biomedical Applications
We report the synthesis and characterization of a novel biomaterial that possesses the unique properties of being both electrically conducting and biodegradable; and thus capable of electronic interfacing with tissue. This polymer was synthesized from conducting oligomers of pyrrole and thiophene that are connected to…
Harder than diamond: Dreams and reality
Analysis of correlations between various physical properties of solids provides a formulation of simple criteria applicable to the search for new superhard materials. The prospects for the synthesis of new substances with the key elastic moduli, whose values approach or even exceed those of diamond are also discussed.…

Collagen Fibers, Reticular Fibers and Elastic Fibers. A Comprehensive Understanding from a Morphological Viewpoint.
Fibrous components of the extracellular matrix are light-microscopically classified into three types of fibers: collagen, reticular and elastic. The present study reviews the ultrastructure of these fibrous components as based on our previous studies by light, electron, and atomic force microscopy. Collagen fibers pre…
Factors Affecting the Moisture Permeability of Lipid-Based Edible Films: A Review
Referee: Dr. Aris Gennadios, Senior Manager, Materials Science, Research and Development, Banner Pharmacaps Inc., P.O. Box 2210, 27261-2210, 4125 Premier Drive, High Point, NC 27265-8144 Moisture transfers inside food products could be controlled or limited by the use of edible films. These are usually based on hydrop…
Nanocapsule Technology: A Review
Nanocapsules are submicroscopic colloidal drug carrier systems composed of an oily or an aqueous core surrounded by a thin polymer membrane. Two technologies can be used to obtain such nanocapsules: the interfacial polymerization of a monomer or the interfacial nanodeposition of a preformed polymer. This article is an…
An idea for thin subwavelength cavity resonators using metamaterials with negative permittivity and permeability
We present and analyze theoretically some ideas for thin one-dimensional (1D) cavity resonators in which a combination of a conventional dielectric material and a metamaterial possessing negative permittivity and permeability has been inserted. It is shown that a slab of metamaterial with negative permittivity and per…
Biopolymers: overview of several properties and consequences on their applications
Recently, interest in composite manufacturing has shifted towards the use of natural fibres as reinforcement because of their environmental benefits. The use of a biodegradable matrix is worth considering since this would result in a completely biodegradable composite. In order to assess the most suitable matrix polym…
