The last decade has seen major progresses in studies of elementary mechanisms of deformation in amorphous materials. Here, we start with a review of physically-based theories of plasticity, going back to the identification of "shear-transformations" as early as the 70's. We show how constructive criticism of the theor…
Fusion proteins created by phage display peptides with tumor cell specificity and the pVIII major coat protein of filamentous phages have been explored recently as a simple and cost-effective means for preparing tumor-targeted liposomes that improve the cytotoxicity of anticancer drugs in vitro. The next step in the d…
Andean wetlands are characterized by their extreme environmental conditions such as high UV radiation, elevated heavy metal content and salinity. We present here the first study on UV tolerance and antioxidant defense of four Acinetobacter strains: Ver3, Ver5 and Ver7, isolated from Lake Verde, and N40 from Lake Negra…
Electromagnetic radiation of 1 - 10 THz range has been found at room temperature in a structure with a point contact between a ferromagnetic rod and a thin ferromagnetic film under electric current of high enough density. The radiation is due to nonequilibrium spin injection between the structure components. By estima…
The set of experimental data on the X-ray-excited luminescence and X-ray induced conductivity of ZnSe are compared to the data on the photoluminescence and photoconductivity. It is experimentally established that the current-voltage characteristics and the kinetics of phosphorescence and current relaxation depend on t…
While diverse fracture characteristics have been observed in liquid metal embrittlement (LME) depending on the solid-liquid metal pairs, the penetration of nanometer-thick liquid metal films along the grain boundary has been identified as one of the key mechanisms for embrittlement in many classical LME systems, such…
One of many limitations for cancer gene therapy is the inability of the therapeutic gene to transfect a sufficient number of tumor cells. Photochemical internalization (PCI) is a photodynamic therapy-based approach for improving the delivery of macromolecules and genes into the cell cytosol. The utility of PCI for the…
In this paper, we have computed the quadratic nonlinear optical (NLO) properties of a class of weak charge transfer (CT) complexes. These weak complexes are formed when the methyl substituted benzenes (donors) are added to strong acceptors like chloranil (CHL) or di-chloro-di-cyano benzoquinone (DDQ) in chloroform or…
In this paper, an MCM-41 single crystal with hexagonal circular bicone form has been observed, and the special morphology of the single crystal appears to be a combination of circular bicone and hexagonal prism forms. As far as we know, the circular bicone faces have not been reported in crystal morphologies before. T…
Using the Coulomb–Green function method and considering the nonrelativistic limit for the two-photon S -matrix element, the right nonrelativistic 2s Rayleigh scattering amplitudes are obtained. Our result takes into account all multipoles, retardation and relativistic kinematics contributions, and the old dipole appro…
Boron nitride thin layers are in situ fabricated on chemical vapor‐deposited boron in ammonia gas. Characterization by X‐ray photoelectron spectroscopy and transmission electron microscopy reveals that the nitridation is dominated by different processes with varying temperatures. Below 1300°C the surface reaction is i…
A Comment on the Letter by Atsushi Ikeda and Kunimasa Miyazaki, [arXiv:1003.5472v2, Phys. Rev. Lett. 104, 255704 (2010)].
Vibrational properties of bulk crystalline barium halides BaCl${}_{2}$, BaBr${}_{2}$, and BaI${}_{2}$ are theoretically investigated for orthorhombic and hexagonal symmetry with ab initio methods in density functional theory. It is demonstrated that the used method is capable of predicting frequencies of vibrational m…
Molecular dynamics simulations were carried out to calculate the free energy change difference of two collagen-like peptide models for Gly --> Ser mutations causing two different osteogenesis imperfecta phenotypes. These simulations were performed to investigate the impact of local amino acid sequence environment adja…
The present research focuses on investigation of the catalytic behaviors of MgCl₂-SiO₂/TiCl₄/THF Ziegler-Natta (ZN) catalysts with fumed SiO₂ variously treated with silane compounds. The non-treated silica (NTS) and other silicas treated with dimethylsilicone fluid (TSDMSF), dimethyldichlorosilane (TSDMDCS), and hexam…
The success of the model-based infrared reflectrometry (MBIR) technique relies heavily on accurate modeling and fast calculation of the infrared metrology process, which continues to be a challenge, especially for three-dimensional (3D) trench structures. In this paper, we present a simplified formulation for effectiv…
Abstract The fire‐retardant properties of a recycled poly(propylene)‐based material were investigated and compared to the non‐recycled formulation. An intrinsic intumescent system and zinc borate were used to flame‐retard these polymers. By mass loss calorimetry, the best results were obtained with 20 wt.‐% of additiv…
Modified supramolecular aggregates for selective delivery of contrast agents and/or drugs are examined with a focus on a new class of peptide-derivatized nanoparticles: naposomes. These nanoparticles are based on the co-aggregation of two different amphiphilic monomers that give aggregates of different shapes and size…
We developed an atomistic model of octamethylcyclotetrasiloxane (OMCTS) liquid confined within the nanospace between two flat mica surfaces. Molecular dynamics simulation was carried out for the liquidlike state where OMCTS liquid is not frozen, while forming molecular layers parallel to the surface. With the aid of a…
The energy and intensity distributions of multiple backscattering of 279, 320, 511 and 662 keV gamma photons emerging from targets of different elements are observed as a function of the target thickness. To characterize the backscattering, probabilities of gamma photons of different energies interacting with differen…
