Due to its unique electronic properties, graphene has already been identified as a promising material for future carbon based electronics. To develop graphene technology, the fabrication of a high quality P-N junction is a great challenge. Here, we describe a general technique to grow single crystalline polyaniline (P…
A nanocrystal or nanoparticle (not fully crystalline) is defined as a particle with size in range of 1 to 100 nm (102 to 107 atoms) from zero (0D) to three dimensions (3D), which exhibits the unique physiochemical properties due to the quantum size effect that cannot be anticipated from bulk counterparts. Strictly spe…
Mg is a biodegradable biomaterial which may release particles (MP) to the environment. The possible cyto- and genotoxic effects of MP derived from magnesium powder (mesh 325) were analyzed on rat osteosarcoma UMR106 cells in order simulate the effect of Mg debris. Neutral red (NR) incorporation and acridine orange/eth…
Abstract Poly(butylene 1,4‐cyclohexanedicarboxylate) (PBCHD) is an environmentally friendly material, as it can be obtained from biomass (although nowadays it is prepared from petroleum resources) and is potentially biodegradable. Moreover, the aliphatic rings along the chains lend interesting characteristics, for exa…
Poly(propylene glycol) (PPG) of moderately high molecular weight (M(n) = 3500 Da) exhibits amphibious behavior in aqueous solution in that it is hydrophilic at low temperature but hydrophobic at high temperature. This property is utilized to generate porous titania thin films with a hierarchical structure consisting o…
Three new bisperylenebisimide-silicon phthalocyanine triads [(PBI)(2)-SiPcs 1, 2, and 3] connected with either rigid or flexible bridges were synthesized and characterized. A new synthetic approach to connect SiPc and PBI moieties through click chemistry produced triad 3 with an 80% yield. In (PBI)(2)-SiPc 1, PBI and…
Summary Reactive extrusion was utilised for starch/poly(butylene adipate co‐terephthalate) (PBAT) blown film production, using maleic anhydride (MA) and citric acid (CA), alone or combined, as compatibilisers. These compounds (2% w/w) were added to the starch/PBAT (55:45) mixture after dispersion on glycerol. More rig…
Silver nanoparticles (AgNPs) have been reductively fabricated on the hydrogen-terminated surface of germanium nanowires (GeNWs), which exhibited moderate reactivity toward the direct reduction of Ag (I) ion to metal nanoparticles in aqueous solution at room temperature. The electronic properties of the AgNPs/GeNWs sys…
We present a tight-binding theory of the Dirac point resonances due to adsorbed atoms and molecules on an infinite two-dimensional graphene sheet based on the standard tight-binding model of the graphene $\ensuremath{\pi}$-band electronic structure and the extended H\"uckel model of the adsorbate and nearby graphene c…
Abstract The mechanical behavior of semicrystalline polymers is strongly dependent on their crystallinity level, the initial underlying microstructure, and the evolution of this structure during deformation. A previously developed micromechanical constitutive model is used to capture the elasto‐viscoplastic deformatio…
In this paper, thermogravimetric analyses, Fourier transform infrared spectra, X-ray powder diffraction, photoluminescence, electron paramagnetic resonance, and superconducting quantum interference device magnetometer are applied to observe the thermal decomposition of Zn 5 (OH) 8 Ac 2 ·2H 2 O to ZnO for understanding…
This paper is dedicated to Charles and Marie-Louise Steele for their exceptional contributions to publication in the field of solids and structures, and, particularly, for founding this journal. A family of basic rate-independent strain gradient plasticity theories is considered that generalize con-ventional J2 deform…
The storage and reduction features of a family of Pt/Rh/BaO/CeO 2 /Al 2 O 3 washcoated monolith catalysts are compared in terms of NO x conversion and product selectivity using H 2 as the reductant. The catalyst composition, monolith temperature, regeneration time, and presence of H 2 O and CO 2 in the feed were syste…
We present SampleRank, an alternative to contrastive divergence (CD) for estimating parameters in complex graphical models. SampleRank harnesses a user-provided loss function to distribute stochastic gradients across an MCMC chain. As a result, parameter updates can be computed between arbitrary MCMC states. SampleRan…
Micromechanical models of porous ferroelectric ceramics have often assumed that the material is fully polarized in a particular direction and/or consists of a single isolated pore. In this work the polarization state in three-dimensional porous polycrystalline ferroelectric networks has been modelled to eradicate the…
Growing within: The reaction of added Ca2+ ions with the CO2 produced by respiration results in the endogenous production of a CaCO3 scaffold in functionalized cells (see picture). These cells act as anticancer drug carriers with pH-sensitive release, and can enhance the cytotoxicity of drugs by increasing the cellula…
To epitaxially grow graphene, metallic catalysts or carbon containing silicon carbide have been typically utilized. The embedded metallic catalyst between graphene and the substrate as well as the expensive silicon carbide substrate create hurdles in the development of graphene-based devices. However, what is inevitab…
2-Oxazolines (2-OZO) are 5-membered cyclic imino ethers whose cationic ring-opening polymerization (CROP) mechanism and resulting polymer properties are extensively studied. However, also 6- and 7-membered cyclic imino ethers can be polymerized via CROP. Together with the much less studied 4- and 5-substituted main-ch…
The dynamics of a collapsing polymer under a temperature quench in dilute solution is investigated by dissipative particles dynamics. Hydrodynamic interactions and many-body interaction are preserved naturally by incorporating explicit solvent particles in this approach. Our simulation suggests a four-stage collapse p…
The new bio-branch of nanotechnology is considered to be one of the fastest emerging fields often called as Nanobiotechnology. Recent studies on exploitation of the natures secrets for the synthesis of inorganic materials are relatively new and exciting area of research with considerable potential for development. Amo…
