The solubilities of (2 R,3 S,4 R )-2,3,4,5-tetrahydroxypentanal (xylose), (2 R,3 R,4 R,5 R )-2,3,5,6-tetrahydroxy-4-[(2 R,3 R,4 S,5 S,6 R )-3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxyhexanal hydrate (maltose monohydrate), (2 R,3 S,4 S,5 R,6 R )-2-(hydroxymethyl)-6-[(2 R,3 R,4 S,5 S,6 R )-3,4,5-trihydroxy-6-(hydrox…
The interaction between two spherical polymer brushes in solvents of variable quality is studied by molecular dynamics simulation and by self-consistent field theory, varying both the radius of the spherical particles and their distance, as well as the grafting density and the chain length of the end-grafted flexible…
Recycling: A self-contained procedure for the recycling of BNH-waste, based on the three major steps: polymer break-up, amine supported catalytic hydrodehalogenation of boron halogens, and the base exchange in borane amine adducts, is developed (see picture). Beyond the original task of recycling spent ammonia borane,…
Enhanced near band gap edge (NBE) emissions of PVA-ZnO nanoparticles were achieved by employing SiO(2)-Au core/shell nanostructures whereas the defect-level emission (DLE) is greatly suppressed. A maximum enhancement of nearly 400% was observed using SiO(2)-Au for the emission with optical resonance at 554 nm. SiO(2)-…
Dual color fluorescence cross-correlation spectroscopy (DC FCCS) experiments were conducted to study the coalescence and aggregation during the formation of nanoparticles. To assess the generality of the method, three completely different processes were selected to prepare the nanoparticles. Polymeric nanoparticles we…
The crystallization process of vanillin in a 1-propanol/water system was investigated. It was found that liquid–liquid phase separation, also termed oiling out, will happen under some conditions. To fully understand this process, the oiling out as well as the following nucleation and crystal growth of this compound we…
Elemental carbon exists in various aesthetically pleasing architectures. These forms include a group of synthesized allotropes with cubic modifications that have taken controversial or even unidentified crystal structures, which makes determining their physical properties difficult. In this study, four novel cubic car…
Shape memory characteristics of a woven glass fibre fabric reinforced epoxy composite (reinforcement content: 38 vol.%) were assessed in three-point bending mode in a dynamic mechanical analysis device and compared to those of the parent epoxy resin. From unconstrained tests, the shape fixity and recovery ratios and t…
A great number of works have focused their research on the synthesis, design and optical properties of gold nanoparticles for potential biological applications (bioimaging, biosensing). For this kind of application, sharp gold nanostructures appear to exhibit the more interesting features since their surface plasmon b…
The heterobimetallic complex CsEu[(+)-hfbc](4) (hfbc = 3-heptafluorobutyryl camphorate), prepared by Kaizaki and co-workers, displays the highest ratio of polarization versus total luminescence (measured by the g(lum) factor), i.e., ~85% of the emitted photons at 595 nm are left-circularly polarized. We present a deta…
As the utilization of advanced composites in structural applications grows, the need for improving their through-thickness properties becomes imperative. Although the behavior of composite laminates under structural and thermal loads has received much attention with their growth in safety critical structures, more eff…
When Fourier transforming radiation total scattering data to the pair distribution function it is common to use a `modification' function to help reduce the termination ripples that would otherwise occur as a result of the finite range and counting statistics of the scattering data. One of the most common functions em…
We present a finite-size scaling study of the liquid-liquid critical point in the Jagla model, a prototype model for liquids that present the same thermodynamic anomalies which characterize liquid water. Performing successive umbrella sampling grand canonical Monte Carlo simulations, we evaluate an accurate density of…

Fouling formation on heat exchanger surfaces due to crystallization of inverse solubility salts is one of the fundamental problems in process industries. Despite numerous studies carried out in recent years, comprehensive understanding of crystallization fouling mechanism remains a challenge to chemical engineers. In…
A simple and straightforward method of self-assembling grafted copolymers was developed to fabricate cross-linked polymer vesicles, which could conjugate anticancer drug cis-platinum and possess the capability of a high drug loading content, and a steady release rate.
We examine ultrafast dynamics in a coupled molecule-plasmon system. Using a new ultrafast Raman technique called surface enhanced-femtosecond stimulated Raman spectroscopy (SE-FSRS), we prove that plasmonic nanoparticles and adsorbed molecules are coupled by the appearance of Fano-like lineshapes, which arise from the…
We present a metamaterial absorber detector array that enables room-temperature, narrow-band detection of gigahertz (GHz) radiation in the S band (2-4 GHz). The system is implemented in a commercial printed circuit board process and we characterize the detector sensitivity and angular dependence. A modified metamateri…
The evolution of the crystallographic orientation field in a polycrystalline sample of copper is mapped in three dimensions as tensile strain is applied. Using forward-modeling analysis of high-energy X-ray diffraction microscopy data collected at the Advanced Photon Source, the ability to track intragranular orientat…
A strategy of surface-free-energy-distribution induced selective growth of Au nanograins (AuNGs) on specific positions of Cu2O octahedron surfaces with a series of morphological evolutions has been demonstrated. The surface energy distribution of Cu2O octahedra generally follows the order of {111} facets < crystal edg…
