porphyrin (TNPP) has been synthesized using the reaction of pyrrole and 4-nitrobenzaldehyde in the presence of propionic acid. The TNPP was used as a new fluorescent chemosensor to determine Ru 3+ with higher selectivity than other ions such as Hg 2+ , CH3Hg + , Ag + , Co 2+ , Cd 2+ , Ni 2+ , Cr 3+ , Fe 3+ , Cu 2+ , o…
BACKGROUND: The design of biomimetic materials that parallel the morphology and biology of extracellular matrixes is key to the ability to grow functional tissues in vitro and to enhance the integration of biomaterial implants into existing tissues in vivo. Special attention has been put into mimicking the nanostructu…
Casting Routes for Porous Metals Production The last decade has seen growing interest in professional public about applications of porous metallic materials. Porous metals represent a new type of materials with low densities, large specific surface, and novel physical and mechanical properties, characterized by low de…
Crystallization of l-alanine in the presence of l-valine and l-tryptophan additives on a circular poly(methyl) methacrylate (PMMA) platform designed for Metal-Assisted and Microwave-Accelerated Evaporative Crystallization (MA-MAEC) technique was investigated. Theoretical simulations predicted homogeneous temperature a…
The present work aims to compare the scratch hardness ( H s ) with the indentation hardness ( H IT ) obtained from nanoindentation measurements of exfoliated graphite/poly (methyl methacrylate) (EG/PMMA) composites. EG/PMMA composites with thickness 50 μm each were produced by in situ melt mixing method. Scratch hardn…
Relaxed force constants (RFC) and vibrational root-mean-square (VRMS) deviations are used for comparative characterization of mechanical properties of canonical 2'-deoxyribonucleosides (2DRs) and 1,2-dideoxyribose molecule, their model sugar residue. It has been shown that RFC and VRMS should be preferred over traditi…
In order to understand the fundamental charge transport in amorphous boron heterostructure devices, we have utilized X-ray photoelectron spectroscopy to determine the valence band offset present at interfaces formed by plasma enhanced chemical vapor deposition of a-B:H and a-BP:H on Si (100) substrates. For both cases…
In order to protect electronic products from Electrostatic Discharge (ESD) damage, multi-layer ceramic capacitors (MLCC) are often used to bypass the transient ESD energy. Most dielectric materials used in MLCC are nonlinear, since the dielectric constant decreases with increasing voltage, reducing the capacitance val…
We have introduced the pentafluorophenyl substituted benzimidazole as a building block of conjugated polymers for optoelectronic applications. We present the synthesis of a copolymer bearing fluorene as the comonomer. A detailed characterization of the novel material including structural, electrochemical and optical (…
It is very important to measure local deformations for an in-depth understanding of mechanical properties and fracture mechanism of structural and functional materials. In this paper, different types of model grid fabrication methods and many types of electron Moiré methods using an electron beam drawing system, a sca…
A new effective model for calculation of the equivalent uniform blast load for non-uniform blast load such as close-in explosion of a one-way square and rectangle reinforced concrete slab is proposed in this paper. The model is then validated using single degree of freedom (SDOF) system with the experiments and blast…
Intermetallics that contain rare-earth elements are particularly interesting because of their temperature- and pressure-dependent structural and physical transitions that make them potential candidates for magnetic applications. This article highlights synthetic routes and structural characterization advancements used…
Olfactory sensory neurons, located in the nasal epithelium, detect and transmit odorant information to the central nervous system. This requires that these neurons form specific neuronal connections within the olfactory bulb and express receptors and signaling molecules specific for these functions. This protocol desc…
The spacer grid is one of the main structural components in a fuel assembly. It supports fuel rods, guides cooling water and maintains geometry from external impact load and cyclic stress by the vibration of nuclear fuel rod, it is necessary to have sufficient strength against dynamic external load and fatigue strengt…
Elastic moduli of 50–250 nm thick Al‐50 at % Cu film alloys deposited by thermal evaporation on Kapton substrates and postformed by thermal diffusion are investigated. Formation of the Al2Cu alloy phase was confirmed by X‐ray photoelectron spectroscopy (XPS). Surface morphology was examined by atomic force microscopy…
Two new metal–organic frameworks based on 5-bromonicotinic acid complexes have been synthesized by hydrothermal reaction with Cd and Co metallic( ii ) salts in the presence of water.
Abstract The effects of retention on formation and drainage by using three-component retention aid systems were examined using a pilot web former. The purpose was to examine whether the relationship between retention and formation could be improved by using systems based on cationic polyacrylamide, structurally differ…
We introduce an electronic model for solar cells taking into account heterostructures with active interfaces and energy resolved volume and interface trap densities. The model consists of continuity equations for electrons and holes with thermionic emission transfer conditions at the interface and of ODEs for the trap…
Hybrid magnetic nanoparticles (mgNP) with a magnetite core diameter of 10 ± 1 nm surface functionalized with oligo(ω-pentadecalactone) (OPDL) oligomers with Mn between 1300 and 3300 g mol−1 could be successfully prepared having OPDL grafted from 200 mg g−1 to 2170 mg g−1. The particles are dispersible in chloroform re…
The antimicrobial peptide dermaseptin 01 (DS 01), from the skin secretion of Phyllomedusa hypochondrialis frogs, was immobilized in nanostructured layered films in conjunction with nickel tetrasulfonated phthalocyanines (NiTsPc), widely used in electronic devices, using layer-by-layer technique. The films were used as…
