The focus of this contribution is on the understanding of solubility that is a prerequisite to any meaningful measurement, reporting, and interpretation of solubility data. A brief reprise of the thermodynamics of solubility is followed by a summary of ‘excess solvent’ and ‘excess solid’ methods of measurement in comm…
The untreated, NaOH and silane-treated naturally woven coconut sheath/polyester composites have been developed using compression molding technique by varying the weight percentage (1, 2, 3, and 5 wt%) of organically modified montmorillonite (MMT) nanoclay to find the mechanical properties as a function of temperature.…
Ein indirekter Weg wurde erstmals eingeschlagen, um poröse organische Käfigverbindungen mit funktionalisierten Hohlräumen zu synthetisieren. Die Methode liefert quantitativ modifizierte Käfige und könnte die Möglichkeit eröffnen, poröse organische Legierungen mit verschiedenen Funktionalitäten herzustellen.
The inhomogeneous phase, which usually exists in graphene oxides (GOs), is a long-standing problem that has severely restricted the use of GOs in various applications. By using first-principles based cluster expansion, we find that the existence of phase separation in conventional GOs is due to the extremely strong at…
The buckminsterfullerene C${}_{60}$ molecules are composed of \ensuremath{\sim}99$%$ naturally abundant ${}^{12}$C carbon atoms having spinless nucleus and thus zero hyperfine interaction. Therefore it has been assumed that the spin diffusion length in C${}_{60}$-based spin-valves is large. We fabricated spin-valves b…
Paclitaxel-loaded shell cross-linked polymeric nanoparticles having an enzymatically and hydrolytically degradable poly(lactic acid) core and a glutathione-responsive disulfide cross-linked poly(oligoethylene glycol)-containing corona were constructed in aqueous solution and investigated for their stimuli-responsive r…
This experiment aimed to investigate the effects of the chitosan (CTS) and water-soluble chitosan (WSC) microspheres on plasma lipids in male Sprague-Dawley rats fed with high-fat diets. CTS microspheres and WSC microspheres were prepared by the spray-drying technique. Scanning electron microscopy (SEM) micrographs sh…
The combination of magnetic particles and layered double hydroxide (LDHs) materials leads to the formation of hierarchical composites that can take full advantages of each component; this is an effective approach for achieving multifunctional materials with intriguing properties. This Concept article summarizes severa…
Colloidal suspensions exhibit shear thinning and shear thickening. The most common interpretation of these phenomena identifies layering of the fluid perpendicular to the shear gradient as the driver for the observed behavior. However, studies of the particle configurations associated with shear thinning and thickenin…
A phase field dislocation dynamics model that can model widely extended dislocations is presented. Through application of this model, we investigate the dependence of equilibrium stacking fault width (SFW) on the material γ-surface in fcc metals. This phase field model includes a direct energetic dependence on a param…
In current study, nanoparticles of NiS were synthesized by applying microwave radiation. The effect of concentration of sulfur source, reaction time, and power of microwave irradiation on the treatment process was investigated. The morphology, structure, and composition of the as-synthesized nanostructures have been c…
Novel engineered nanomaterials (ENMs) are being introduced into the market rapidly with little understanding of their potential toxicity. Each ENM is a complex combination of diverse sizes, surface chemistries, crystallinity, and metal impurities. Variability in physicochemical properties is poorly understood but is c…
Three new series of bent-shaped molecules with 4-chlororesorcinol, 4-bromoresorcinol or 4-fluororesorcinol as the central unit, and azobenzene with different alkoxy chain length as side arms were synthesised. The mesophase behaviour was investigated by polarising optical microscopy, and differential scanning calorimet…
Abstract Open‐cell hydrophilic polymer foams are prepared through oil‐in‐water Pickering high internal phase emulsions (HIPEs). The Pickering HIPEs are stabilized by commercial titania (TiO 2 ) nanoparticles with adding small amounts of non‐ionic surfactant Tween85. The morphologies, such as average void diameter and…
In recent research it was found that the fundamental shear-localizing instability of amorphous solids under external strain, which eventually results in a shear band and failure, consists of a highly correlated array of Eshelby quadrupoles all having the same orientation and some density ρ. In this paper we calculate…
Graphene is a promising alternative to indium tin oxide for use in transparent conducting electrodes. We review recent progress in production methods of graphene and its applications in optoelectronic devices such as touch panel screens, organic photovoltaic cells, organic light emitting diodes and thin film transisto…
In this letter, we present the first graphene FET operation for zero-bias resistive FET mixers, utilizing modulation of graphene channel resistance rather than ambipolar mixer operations, up to 20 GHz. The graphene FETs with a gate length of 0.25$\mu \hbox{m}$have an extrinsic cutoff frequency$f_{T}$of 40 GHz and a ma…
Heptacoordinated nickel(II) complexes characterized by substantial Ising-type single-ion anisotropy have been involved in the construction of two pentanuclear [Ni3W2] compounds by association with [W(CN)8](3-). For one of them, slow relaxation of magnetization was observed to occur concomitantly with antiferromagnetic…
Semiconducting nanomaterials such as single-walled carbon nanotubes (SWCNTs) and nanocrystals (NCs) exhibit unique size-dependent quantum properties. They have therefore attracted considerable attention from the viewpoints of fundamental physics and functional device applications. SWCNTs and NCs also provide an excell…
The geometry, electronic structure, and catalytic properties of Pt catalyst supported on the nonmetal doped-graphene (denoted as D-graphene, where D represents the B, Si, O and P dopant) substrates are investigated using the first-principles method. The nonmetal atoms (NA) have small adsorption energies and prefer to…
