The interaction between individual plasmonic nanoparticles plays a crucial role in tuning and shaping the surface plasmon resonances of a composite structure. Here, we demonstrate that the detailed character of the coupling between plasmonic structures can be captured by a modified "circuit" model. This approach is ge…
We present a simple approach to calculate the thermodynamic properties of single Kondo impurities including orbital degeneracy and crystal field effects (CFE) by extending a previous proposal by Schotte and Schotte (1975 Phys. Lett. 55A 38). Comparison with exact solutions for the specific heat of a quartet ground sta…
We consider the Jeffreys-type equation as the foundation in three different models of mass transfer, namely, the Jeffreys-type and two-phase models and the D(1) approximation to the linear Boltzmann equation. We study two classic (1+1)-dimensional problems in the framework of each model. The first problem is the trans…
A theoretical study based on the use of admittance loci method in the design of surface plasmon resonance (SPR) based structure using Ag-Au bimetallic alloy film of different alloy fractions and nanoparticle sizes has been reported along with some interesting performance related simulated results at 633 nm wavelength.…
Abstract In this study, a salt‐leaching using powder (SLUP) scaffold with penetrated macropores was proposed to enhance cell proliferation. A SLUP scaffold is a salt‐leaching scaffold with an arbitrary pore configuration. Although SLUP scaffolds have several advantage over traditional salt‐leaching scaffolds, the cell…
Single crystal x-ray diffraction, magnetic susceptibility (M), heat capacity (C), and electrical resistivity (ρ) measurements are reported for specimens of the new tetragonal compound CePd3Al9, which forms in a new structure type. X-ray diffraction measurements reveal that the nearest neighbor Ce-Ce distances are larg…
BINAP-metal complexes were prepared as extractant for enantioselective liquid-liquid extraction (ELLE) of amino-(4-nitro-phenyl)-acetic acid (NPA) enantiomers. The influence of process variables, including types of organic solvents and metal precursor, concentration of ligand, pH, and temperature on the efficiency of…
Effects of low energy electron beam irradiation (LEEBI) of planar and nanopillar InGaN/GaN multiquantum well light emitting diode structures are discussed. The bands observed in microcathodoluminescence (MCL) spectra were attributed to recombination involving two types of InGaN quantum dots with lower (2.92 eV MCL ban…
Barium calcium sulfoaluminate (C2·75B1·25A3S¯) mineral was prepared with analytical pure chemical reagents calcium carbonate, aluminium oxide, barium carbonate and barium sulfate. The sintering temperature and formation mechanism of the C2·75B1·25A3S¯ mineral were investigated by X-ray diffraction, differential scanni…
The configurational dynamics of a polyelectrolyte (PE), subjected to a simple shear flow, is studied using Brownian dynamics (BD) and Dissipative Particle Dynamics (DPD) simulations of a bead-spring model with explicit counterions. We explore the effect of counterion condensation on the tumbling and extension of PEs b…
Non-close-packed breath figure arrays were observed to form at the periphery of close-packed arrays. We propose a mechanism for their formation and show a proof-of-concept that these non-close-packed pore arrays are formed due to a reversal of breath figure formation, and hence introduce a novel route to the self-asse…
Although phosphorus adsorption on semiconductors has potential applications in sensors, adhesion promoters, wear-resistant coatings, and monolayer doping for ultrashallow junction transistors, it has been the subject of few studies. Adsorption of trimethyl phosphite at the Ge(100)-2 × 1 surface is studied in this work…
The effect of gold nanoseeds with different sizes on the gold shell was investigated. Gold nanoparticles of two different sizes (∼3 nm and ∼15 nm) were prepared and attached to the surface of amine functionalized silica coated iron oxide nanoparticles. The gold nanoparticles assembled on the surface were used as seeds…
UV-induced thiol-ene crosslinked films composed of linear methacrylate copolymers having pendant enes (MCPenes) are reported. An approach involving a combination of controlled radical polymerization to synthesize well-controlled pendant hydroxyl containing copolymers (MCPOHs) with the following facile carbodiimide cou…

The effect of hydrogen adsorption on the magnetic properties of an Fe${}_{3}$ cluster immersed in a Cu(111) surface has been calculated using density functional theory and the results used to parametrize an Alexander-Anderson model which takes into account the interaction of $d$ electrons with itinerant electrons. A n…
Composite polymer devices have gained considerable interest in biomedical applications. In this work, a composite poly(lactic-co-glycolic acid)/poly(ε-caprolactone) (PLGA/PCL) microsphere with a layered architecture and an island–sea topography was developed. PCL was found to occupy the shell layer of the microsphere,…
Small amounts of water (between and 0.05 and 0.35% V/V) critically determine the morphology and plasmon band of Au/ZnO nanostructures obtained by Au 3+ photoreduction on ZnO nanoparticles dispersed in 2-propanol. All the synthesized materials exhibit plasmon induced activity to drive the solvent oxidation; however, th…
Nanocrystalline cellulose (NCC) was used to improve the anti-yellowing property of polyurethane (PU). The NCC was modified with 3-glycidoxypropyltrimethoxysilane (GPTMS) to enhance its compatibility with PU, and the surface-modified NCC was characterized by contact angle (CA), X-ray powder diffraction (XRD), and therm…
The axolotl Ambystoma mexicanum is one of the most used model organisms in developmental and regenerative studies because it is commonly said that it can reconstitute a normal and fully functional forelimb/hindlimb after amputation. However, there is not a publication that has described in detail the regeneration of t…
