The optical mechanism for imprinting one-dimensional grating structures into thin films of a light-sensitive monodomain liquid crystal elastomer is investigated by analyzing the time dependence of optical diffraction properties. The recording kinetics shows an irregular oscillatory behavior, which is most expressed at…
In this paper, we examine the behavior of the High-Rate Brittle Microplane (HRBM) concrete model based on a series of penetration experiments. These experiments were conducted with three different slab thicknesses (127, 216 and 254 mm) that provided a significant challenge for the numerical simulations. The 127 mm sla…
The effect of change of solvent type on the rate of cure of a polyol with an isocyanate was measured using a range of different techniques. The initial stages of the cure process were followed using viscosity and Fourier transform infrared spectroscopy [FTIR] measurements. The gelation point was observed using viscosi…
Abstract Poly(ethylene terephthalate) (PET)/inorganic fillers were prepared by a melt‐spinning method, and their morphologies and properties were investigated. Four inorganic fillers were studied and compared: calcium carbonate, calcium silicate, magnesium hydroxide, and silica fume. All of the fillers were modified w…
Abstract To improve the thermal properties of linear low‐density polyethylene (LLDPE), the CaCO 3 /LLDPE nanocomposites were prepared from nanometer calcium carbonate (nano‐CaCO 3 ) and LLDPE by melt‐blending method. A series of testing methods such as thermogravimetry analysis (TGA), differential thermogravimetry ana…
The intermetallic clathrate Ba8Ga16Sn30 (BGS) is dimorphic, possessing α-phase (type-VIII) and β-phase (type-I). To determine the stability ranges of the two phases, we performed a study of the phase diagram by combining differential thermal analysis (DTA) and power X-ray diffraction (XRD) on both samples of bulk sing…
Abstract The cure kinetics of two epoxidized hemp oil (EHO) based bioresins were studied and compared under both dynamic and isothermal conditions using differential scanning calorimetry (DSC). Neat triethylenetetramine (TETA) for the first system and a combination of isophorone diamine (IPD) and TETA for the second s…
We investigate the optical properties of mono- and double-layer asymmetric fishnet metamaterials with orientated elliptical holes, which exhibit exotic spectral and polarization rotating characteristics in the visible spectral range. Our results show that nontrivial orientations of the holes with respect to the recipr…
To optimize tumor targetability of nanosized liposomes for application as drug carriers, various liposomes are prepared by incorporating different amounts (10, 30, and 50 wt%) of cationic, anionic, and PEGylated lipids into neutral lipid. In vivo near-infrared fluorescence images reveal that PEG-PE/PC liposomes displa…
We demonstrate that near-edge X-ray-absorption fine-structure spectra combined with full-field transmission X-ray microscopy can be used to study the electronic structure of graphite flakes consisting of a few graphene layers. The flake was produced by exfoliation using sodium cholate and then isolated by means of den…
The synthesis and characterization of four metalloporphycenes containing a [MCp*] + (Cp* = pentamethylcyclopentadiene; M = Rh , Ir , and Ru ) fragment directly bonded to the π-framework of the macrocycle were obtained. The electrochemical and optical properties of these complexes, studied in their respective free-base…
A new method for ultrathin grafting of pNIPAm on PDMS surfaces is introduced that employs plasma activation of the surface followed by thermal polymerization. This method is optimized for human primary SMC attachment and subsequent intact cell sheet detachment by lowering the temperature. The contractile gene expressi…
Abstract Organic/inorganic hybrid materials (hybrimers) were fabricated by the photocationic polymerization of sol–gel‐derived cycloaliphatic epoxy oligosiloxane (CAEO)/oxetane blends. The CAEO/oxetane blends showed faster photocationic polymerization rates compared to a CAEO resin. The CAEO/oxetane hybrimers showed a…
A study has been conducted on a Cu(Sn) solid solution to examine the role of the vacancy wind effect on interdiffusion. First, the interdiffusion and the intrinsic diffusion coefficients are calculated. The trend of the interdiffusion coefficients is explained with the help of the driving force. Following this, the tr…
Microwave measurements of the in-plane dielectric function of the spin-liquid candidate $\ensuremath{\kappa}$-(BEDT-TTF)${}_{2}$Cu${}_{2}$(CN)${}_{3}$ revealed anomalies below 300 K that indicate that charge and spin degrees of freedom are correlated down to 1.8 K. If the first anomaly around 100 K can be explained pa…
The influence of surface nanoroughness on the static and dynamic behavior of a solid–water–dodecane contact line is investigated. Surface roughness is found to affect the substrate static and dynamic wettability for root-mean-square roughnesses below 7 nm. The kinetics of liquid–liquid displacement is slowed down dras…
We present many-body calculations of superconducting pair-pair correlations in the ground state of the half-filled-band Hubbard model on large anisotropic triangular lattices. Our calculations cover nearly the complete range of anisotropies between the square and isotropic triangular lattice limits. We find that the s…
Abstract Dense 〈001〉‐oriented (K x Na 1 − x ) 0.946 Li 0.054 NbO 3 (K x NLN) ceramics with high texture quality (Lotgering factor F 001 > 80%) and excellent piezoelectric properties were produced by templated grain growth using plate‐like NaNbO 3 particles as templates. Compared with randomly oriented K x NLN ceram…
In recent years, it has become increasingly clear that many enzymes are catalytically "promiscuous". This can provide a springboard for protein evolution, allowing enzymes to acquire novel functionality without compromising their native activities. We present here a detailed study of Pseudomonas aeruginosa arylsulfata…

The properties of the synthesized nanostructures are studied using X-ray diffraction, Transmission Electron Microscopy (TEM), Photoluminescence (PL), Ultraviolet-Visible absorption, Laser Raman and Fourier transform Infrared (FTIR) spectroscopy. The thermal…
