The classical three-dimensional Cerruti problem of an isotropic half-space subjected to a concentrated tangential load on its surface is revisited here in the context of dipolar gradient elasticity. This generalized continuum theory encompasses the analytical possibility of size effects, which are absent in the classi…
Objective: In developing countries, population explosion is one of the most important causes of poverty and pollution. Therefore, several approaches have been investigated to decrease fertility, including hormonal, chemical and immunological approaches. However, no suitable method has been found to be effective and fr…
In the last decade, nano-structured materials have gained a significant interest for applications in solar cells and other optical and opto-electronic devices. Due to carrier confinement, the absorption characteristics in these structures are quite different from the absorption in bulk materials and thin films. Optica…
This research work was undertaken to investigate the spectroscopic, morphological and rheological properties of polymer blends made of recycled Polyethylene terephthalate (PET), Polyethylene (PE) and Polyvinylchloride (PVC). Different blends of these polymers were made by varying composition of PET. Each recycled blen…
π-Extended nine-ring-fused linear thienoacenes 1a–c with internal thieno[3,2-b;4,5-b′]dithiophene substructures were synthesized. Their optical and electrochemical properties were investigated. Thin-film transistor characteristics showed all compounds displayed high device reproducibility and nearly no dependence on s…
The transmission line method is a very efficient method for dynamic modelling of flow in pipelines and uses delay elements to represent wave propagation. In this article, an existing transmission line method model is investigated and shown to have some deficiencies. An alternative technique is introduced to enhance th…
The induction of angiogenesis and the promotion of tumor growth and invasiveness are processes critical to metastasis, and are dependent on reciprocal interactions between tumor cells and their microenvironment. The formation of a clinically relevant tumor requires support from the surrounding stroma, and it is hypoth…
Tissue engineering provides a promising tool for creating load-bearing cardiovascular tissues. Ideally, the neotissue produced by cells possesses native strength and anisotropy. By providing contact-guiding cues with microfibers, scaffold directionality can guide tissue organization. However, scaffolds transiently deg…
A novel amphiphilic chitosan derivative of N,N-dimethylhexadecyl carboxymethyl chitosan (DCMCs) was synthesized. The structure of DCMCs was confirmed via FT-IR and (1)H NMR, and the critical micelle concentration (CMC) was investigated by fluorescence spectroscopy. The results indicated that DCMCs has hydrophilic carb…
The initial step of O 2 evolution reaction on a TiO 2 surface is a long-standing puzzle. A recent scanning tunneling microscopy experiment showed that the H 2 O molecule adsorbed on rutile TiO 2 (110) surface could decompose under ultraviolet illumination (Tan, S. J.; et al. J. Am. Chem. Soc ., 2012, 134, 9978). The u…
Docking algorithms that aim to be applicable to a broad range of ligands suffer reduced accuracy because they are unable to incorporate ligand-specific conformational energies. Here, we develop a set of Carbohydrate Intrinsic (CHI) energy functions that quantify the conformational properties of oligosaccharides, based…
The self-assembly of the amyloid-β (Aβ) peptide of 39-43 amino acids into senile plaques is one hallmark of Alzheimer's disease (AD) pathology. While A2 V carriers remain healthy in the heterozygous state, they suffer from early onset AD in the homozygous state. As a first toward understanding the impact of A2 V on Aβ…
The silver surface plasmon resonance (SPR) sensor has long been explored due to its intrinsic sensitivity enhancement over the conventional single-layered gold SPR sensor. However, the silver SPR sensor has not been exploited for practical applications because of pronounced instability problems. We propose a novel gol…
We report the chemical fabrication of metallic glass nanoparticles (MG-NPs). Using commercially available Pd, Ni, and P precursors, size-controlled amorphous Pd–Ni–P NPs were obtained by a one-pot solvothermal synthesis procedure. Differential scanning calorimetry identified typical MG properties of the unsupported Pd…
Nylon 11,11 is a new odd–odd polyamide with multiple crystalline structures. The wide‐angle X‐ray scattering indicated that the structure of quenched sample was not amorphous but a γ‐form crystal with a relatively low crystallinity. The α‐form and the γ‐form crystal of nylon 11, 11 could be obtained by annealing the q…
The bicontinuous lyotropic liquid phases surrounded by the isotropic phase form monocrystals with well-developed facets. We investigate the structure and stability of the facets formed by the bicontinuous phase of Pn3̅m symmetry, at three preferred directions, which are developed on a spherical droplet of Pn3̅m phase…
Self‐hybrid thermoplastic composites (combination of two fiber sizes) were obtained by injection molding using pine or agave fibers with polypropylene (PP). The effect of self‐hybridization was determined through mechanical properties and water absorption for different total fiber contents between 10 and 30% wt. The r…
The crystallization of poly(lactic acid) (PLA) is usually slow and related to the content of d -lactide. A new approach is suggested in this work to accelerate the crystallization of PLA via the synergistic effect of nanofibril nucleating agent (dibenzylidene sorbitol, DBS), plasticizer (poly(ethylene glycol), PEG) an…
To commercially produce consumer products using engineering polymers, it is very important to control the physical properties of the material. However, quality control of the material is not easy because of many reasons such as cost reduction, cleaning issues, the use of scraps, etc. In many cases, even a small amount…
Electrochemical impedance spectroscopy was used to study the transport properties of the three-layer Dion–Jacobson phase HLa 2 Ti 2 TaO 10 in the temperature range of interest (250–475 °C) for intermediate temperature fuel cells. The compound was prepared by proton exchange of RbLa 2 Ti 2 TaO 10, which in turn was mad…
