The occurrence and preservation of aragonite in eclogite-facies rocks of north-eastern Corsica is linked to an uncommon microtexture. Aragonite exclusively occurs as oriented fibres in garnet crystals of a graphitic, more or less siliceous marble that immediately overlies a serpentinite body of the meta-ophiolitic uni…
The ab initio full potential linearized augmented plane wave (FP-LAPW) method within density functional theory (DFT) was applied to study the effect of composition on the structural, electronic, optical and thermodynamic properties of SrS1−xSex, SrS1−xTex and SrSe1−xTex ternary alloys. For exchange–correlation energy…
Molecule immobilization in hydrothermally synthesized titania nanotubes is investigated by 13 C solid-state NMR aided density functional theory calculations. The changes of 13 C NMR spectra before and after immobilization indicate that phenols are chemisorbed and that aliphatic acid is possibly physisorbed in titania…
Abstract A new method has been developed to determine the probability of miscibility in binary polymer blends through hydrodynamic interaction. This is achieved by the measurement of the free volume content in blends of carefully selected systems—styrene acrylonitrile (SAN)/poly(methyl methacrylate) (PMMA), PMMA/poly(…
This study reports a calibration of Raman band positions for the determination of the Na/K ratio in disordered alkali feldspars. Crystals along the join sanidine-analbite were synthesised in steps of 10 mol% by ion exchange from a natural sanidine from Volkesfeld and were analysed by electron microprobe. Calibrations…
A diffusion model including shrinkage has been developed for predicting the change of moisture content in banana foam mats during drying. Two solution methods, moving boundary using variable grid and immobilizing boundary using the Lagrangian referential coordinate, were used in exploring their capabilities to predict…
A new cohesive micromechanical modeling framework is presented for the progressive damage analysis of laminated composite materials and structures. The cohesive micromechanics (CM) modeling approach is based on simplified 3D unit cell with incremental and damage formulations. The unidirectional CM model formulated in…
A "stable" electrohydrodynamic jet is used to print arrays of colloidal suspensions on hydrophobic surfaces. Printed lines break up into sessile drops, and capillary forces guide the self-assembly of colloidal particles during the evaporation of the liquid, resulting in arrays of colloidal single particles or particle…
Fullerene has a unique structure and notable chemical and physical properties, which have been studied in diverse fields including biological applications. The extremely poor solubility of fullerenes in water limits their usage for biomedical applications. In this study, we synthesized polyamidoamine dendrimers having…
We investigated the microstructure and flux pinning capability of the bulk (Bi,Pb) 2 Sr 2 Ca 2 Cu 3 O y system (denoted as (Bi, Pb)-2223) with 0.0–0.3 wt% nano-size ZrO 2 particles (10–20 nm) addition synthesized by solid state reaction. Phase analysis by x-ray diffraction (XRD), granular structure examination by scan…
Single-photon ionization through vacuum ultraviolet (VUV, 10.5 eV) and soft X-ray (extreme ultraviolet, EUV, 26.5 eV) laser radiation is successfully employed for the study of the reactions of neutral vanadium oxide clusters (V(m)O(n)) with sulfur dioxide (SO2) in the gas phase. V(m)O(n) clusters are generated by reac…
We report on optical measurements of the 1D Heisenberg antiferromagnet KCuF3. The crystal-field excitations of the Cu2+ ions have been observed and their temperature dependence can be understood in terms of magnetic and exchange-induced dipole mechanisms and vibronic interactions. Above TN we observe a new temperature…
Abstract The nitrogen content in tantalum nitride (TaN x ) thin films, where x indicates that TaN x is not generally stoechiometric, can be measured directly by XPS. This is the purpose of the present study. However, the XPS spectra of TaN x present electron energy loss spectroscopy (EELS) peaks that lead to a complex…
A novel three-dimensional porous coordination polymer {[CuLBr]·0.5H 2 O} n, solvothermally synthesized by the self-assembly of 4,4′-H 2 bpz (L = 4,4′-H 2 bpz = 3,3′,5,5′-tetramethyl-4,4′-bipyrazole) and CuBr, has a non-centrosymmetric polar packing arrangement, resulting in a strong second harmonic generation response…
In certain applications copolymer P123 (E21P67E21) is dissolved in water-ethanol mixtures, initially to form micellar solutions and eventually to gel. For P123 in 10, 20, and 30 wt % aqueous ethanol we used dynamic light scattering from dilute solutions to confirm micellization, oscillatory rheometry, and visual obser…
The Taguchi method is a statistical approach to overcome the limitation of the factorial and fractional factorial experiments by simplifying and standardizing the fractional factorial design. The objective of this study was to optimize the fabrication of gelatin nanoparticles by applying the Taguchi design method. Gel…
Cardiac tissue engineering has a potential to provide functional, synchronously contractile tissue constructs for heart repair, and for studies of development and disease using in vivo-like yet controllable in vitro settings. In both cases, the utilization of bioreactors capable of providing biomimetic culture environ…
We report an angle-resolved photoemission study of the electronic structure of the pseudogap state in La 1.48 Nd 0.4 Sr 0.12 CuO 4 ( T c <7 K). Two opposite dispersing Fermi arcs are the main result of this study. Several scenarios that can explain this observation are discussed.
The objective of this work was to study the changes of optical properties of apple (Golden Delicious) slices during drying. The optical parameters compared on the basis of Hunter values (L, a, b) changes as well as total color difference (Δ E) and browning index (BI). The effect of coating materials including carboxym…
Elastin is a vital structural and regulatory matrix protein that plays an important role in conferring elasticity to blood vessel wall. Previous tissue engineering approaches to regenerate elastin in situ or within tissue engineering constructs are curtailed by innate poor elastin synthesis potential by adult vascular…
