In situ synthesized TiB2-reinforced TiAl composites usually possess high strength. However, it is very expensive to use B powder to synthesize TiB2 particles. Moreover, the strength enhancement of TiB2/TiAl composite is generally at the cost of plasticity. In this study, in situ dual reinforcement TiB2-Ti2AlC/TiAl com…
ABSTRACT Superabsorbent copolymer hydrogels based on N,N‐dimethylaminoethyl methacrylate (DMAEMA) and 2‐acrylamido‐2‐methylpropane sulfonic acid (AMPS) were synthesized by free‐radical cross‐linking copolymerization using a bifunctional cross‐linking agent diethylene glycol dimethacrylate (DEGDMA). Poly(DMAEMA‐co‐AMPS…
Anatase and brookite TiO2 mesoporous layers were prepared at a low temperature (150 °C) from binder-free precursors based on the dehydration reaction of surface hydroxy groups for interparticle connection. Their electron-collecting performance in perovskite solar cells was investigated. With more uniform perovskite la…
In this paper, the experimental behavior of grid cylindrical composite structures, which are used widely in engineering structures, under ballistic impact is investigated. For this purpose, some grid cylindrical composite specimens were manufactured by the filament winding process and perforated by projectile using th…
Abstract Application of a new method—high-sensitivity measurements of periodic stress-induced induction (reversible Villari effect, RVE)—allows us to uncover new effects in the low-field behaviour of different magnetic phases of polycrystalline Dy. A loss of magnetoelastic coupling (Villari critical point) is found ar…
The effect of losses in photonic crystal structures on transmittance and reflectance has been studied by numerical techniques, and compared to fabricated macroporous silicon samples. Material absorption and tolerances of the pores play an essential role in determining performance in optical applications. The relevance…
This study quantitatively evaluates the antifouling action of the continuous physical treatment with electromagnetic fields (EMFs) of seawater used as heat exchanger fluid in an open rack vaporizer (ORV) pilot plant to reduce the growth of biofouling on external rib-tube surfaces. The results demonstrate that the biof…
The Hildebrand solubility parameters of amidium ionic liquids were investigated using the approach of intrinsic viscosity. It was discovered that the nature of the anion influences the Hildebrand solubility parameters by which distillable trifluoromethanesulfonate- (TfO-) based ionic liquids present higher Hildebrand…
A supramolecular poly-electrolyte complex (SPEC) comprising poly-electrolyte acrylic acid with supramolecularly complexed guanidium is reported. This complex shows pH responsive phase transitions, which are described and characterized using microscopy, spectroscopy, density functional theory studies and Monte Carlo si…
Young's relation is based on the equilibrium of horizontal components of surface tensions for a liquid droplet on a "rigid" substrate without addressing the substrate deformation induced by the net vertical component of surface tensions. Upon realizing the importance of wetting in controlling the integrity of flexible…
Abstract Iridium(III) complex [Ir(ppy)2(tmBBI‐H2)](PF6) (IrBBI‐H2) has been exploited as an anion receptor. In this complex, the cis‐diamine function of the bibenzimidazole is coupled in such a way to the photophysics of the iridium metal core that the photophysics is influenced by hydrogen bonds in the ligand periphe…
BACKGROUND: Salicylic acid and its derivatives are widely used drugs with potential toxicity. The main areas of salicylate derivatives determination are biological liquids and pharmaceuticals analysis. RESULTS: Silica-titania xerogel has been used for solid phase spectrophotometric determination of various salicylate…
Well‐aligned, high aspect‐ratio and open‐ended TiO2 nanotube arrays secured within a Ti foil (TiO2 nanotubes cartridge) were successfully prepared through the double‐sided anodization method. With ∼210 µm of nanotube length, the anodic growth of TiO2 was accelerated and stabilized by the lactic acid‐containing ethylen…
Titanium dioxide (TiO2) nanoparticles are extremely attractive materials for numerous applications, especially in the anatase form. We have made these shaped, <10 nm anatase nanoparticles (NPs) via the supercritical (SC) drying of a titania sol, made by a “green” aqueous sol–gel nanosynthesis route. The SC drying was…
We study the thermal and nonthermal steady-state scaling functions and the steady-state dynamics of a model of local quantum criticality. The model we consider, i.e., the pseudogap Kondo model, allows us to study the concept of effective temperatures near fully interacting as well as weak-coupling fixed points. In the…
We study the vibrational spectra of small neutral gold (Au2-Au10) and silver (Ag2-Au5) clusters using the vibrational self-consistent field method (VSCF) in order to account for anharmonicity. We report harmonic, VSCF, and correlation-corrected VSCF calculations obtained using a vibrational configuration interaction a…
Hydrogen, as an energy carrier, is widely regarded as a potential cost-effective, renewable, and clean energy alternative to fossil fuels in order to mitigate the energy shortage and environmental pollution that are currently being faced. The rapid development of advanced materials in hydrogen production, storage, and…
PURPOSE: In carbon-ion radiotherapy treatment planning, the planar integrated dose (PID) measured in water is applied to the patient dose calculation with density scaling using the stopping power ratio. Since body tissues are chemically different from water, this dose calculation can be subject to errors, particularly…
Additive manufactured scaffolds are fabricated from three commonly used biomaterials, polycaprolactone (PCL), poly (L\DL) lactic acid (P(L\DL)LA), and poly(ethylene oxide terephthalate)/poly(butylene terephthalate) (PEOT/PBT). Scaffolds are compared biologically and tribologically. Cell-seeded PEOT/PBT scaffolds cultu…
Abstract In this paper, we study theoretically spasers based on multipolar Fano resonances in disk-ring nanostructures covered with a silica layer doped with Yb 3+ :Er 3+ used as the gain material. The electric field amplitudes at the quadrupolar mode (lasing wavelength) and the octupolar mode (pumping wavelength) are…
