In order to study new porphyrin complexes, a novel zinc porphyrin ZnTCPP(H2O)•MeOH [TCPP = meso-tetra(4-carboxyphenyl)porphyrin; MeOH = methanol] has been designed, prepared and characterized by a single-crystal X-ray diffraction method.The title complex crystallizes in the orthorhombic system with a Cmca space group…
In earlier rumor spreading models of the real world complex networks, nodes contact all of their neighbors at each time step.In more realistic scenario, a node may contact only some of its neighbors to spread the rumor.The rumor spreading rate may also depend on the degree of the spreader and ignorant nodes.We have gi…
Pressurized conduits transporting liquids such as freshwater, storm-water, wastewater, oil and gas often experience partial blockages or leakages during their life time due to physical and/or chemical processes. In water supply, these anomalies result in about 30% of water loss and more than 30% of energy waste. Trans…
Novel, controlled release drug delivery systems have transformed therapeutics used in modern medicine but exhibit limitations for treating various diseases. Biodegradable polymers have been extensively studied to overcome such challenges. Through incorporating therapeutic bioactives into a polymer backbone via hydroly…
A phenomenological thermodynamic theory is applied to investigate the effect of misfit strain and electric field on the electrocaloric effect of P(VDF-TrFE)/SrTiO 3 bilayer thin films. Theoretical results indicate that the low electric field results in the decrease of the average polarization with the increase of the…
The density-normalized effective ionization coefficient (α − η)/ N (α and η are the ionization and attachment coefficients respectively), the electron drift velocity V e and density-normalized longitudinal diffusion coefficient ND L in trifluoromethane (CHF 3 ) and carbon tetrafluoride (CF 4 ) were measured using a pu…
In recent years, electrically conductive fabrics have been widely used in many fields such as medicine, sensors, sport, electrostatic discharge, electromagnetic interference (EMI) shielding and military applications. This study examines the effects of weft yarn types and weave types on the surface electrical resistivi…
-1 based on the dry weight of fibres. The properties of the MDF produced were compared with control specimens. Three hot press times of 5, 6 and 7 min were used. Results showed that the highest physical and mechanical properties were observed in the 5-min 8% nanocopper treatment. Heat transfer property of copper facil…
We report on a peptide-based hydrogel that can stimulate the growth of the bacterium Delftia.
By using first principles calculations, we propose a codoping method of using acceptors and donors simultaneously to realize low-resistivity and high carrier concentration p-type ZnS with wurtzite structure. The ionization energy of single NS can be lowered by introducing the IIIZn-NS (III = Al, Ga, In) passivation sy…
Two new tridentate(NNO)-bidentate(NN) compartmental ligands, HL(5) and HL(6), are synthesized from pyridine and benzimidazole synthons. They react in aqueous solution under physiological conditions with Zn(II), Ln(III), or a mixture thereof, to yield complexes of different stoichiometries, 1:3, 2:2, 2:3, 1:1:3, the sp…
Distribution of fracture toughness value of amorphous SiC fiber (Tyranno ZMI, Ube Industries, Ltd.) and statistical feature of distribution of fracture strength at various notch sizes were studied analytically. The fracture toughness values, estimated for the fiber specimens with mode I type straight-fronted edge notc…
Silica nanospheres have attracted tremendous interest due to their importance in extensive applications. However, the direct large‐scale fabrication of silica nanospheres with controlled morphology and high purity remains a significant challenge. In this work, silica nano‐/submicron spheres were successfully synthesiz…
The influence of the functionalisation of fully or partially condensed POSS cages on the properties of engineering thermoplastic-based nanocomposites is studied. POSS with different organic substituents were selected in accordance with the structure and chemical composition of the host polymer and melt mixed with the…
The features of low-frequency dielectric losses in the improper ferroelectric crystal of terbium molybdate Tb2(MoO4)3 were investigated in the vicinity of the Curie point. To explain the relations observed, the attenuation mechanism of low frequency electrical oscillations at first order phase transitions was used, wh…
Electrogenerated chemiluminescence (ECL) behavior of a bismuth sulfide nanorods modified glassy carbon electrode (NR-GCE) was investigated in alkaline aqueous solution for the first time. One weak ECL peak of the NR-GCE was observed around -1.70 V when the electrode potential was scanned from 0.0 V to -2.0 V. The inte…
Polymer/silica nanocomposites have substantial commercial potential due to their range of useful properties. The dispersion of nanofillers in the polymer matrix is a key factor in determining the composite property enhancement. We introduced a combination of non–covalent and covalent surface modification to pre–treat…
If anyone begins to think about the term ultrasound, the first thing that comes to the mind is the fact that it is used in animal communications (e.g., bat navigation and dog whistles). Also, one may start to think that this term is familiar in daily life and has been used many times in medicine applications for foeta…
We report on the method of enhancement of the electrical conductivity of poly(3,4-ethylene dioxythiophene):poly(4-styrenesulfonate) (PEDOT:PSS) films through a treatment with newly found organic additives, such as ethylene carbonate (EC) and ethylene sulfite (ES). Addition of these secondary dopants to PEDOT:PSS aqueo…
Development and testing of a novel armor system that defeats high-velocity projectiles and penetrators is described, from a phenomenological perspective. The process is covered where fundamental principles of shock mechanics and high fidelity computational physics (HFCP) simulations are used to create the armor system…
