During the processes of nucleation and growth of a precipitate cluster from a supersaturated solution, the diffusion flux between the cluster and the solution changes the solute concentration near the cluster-solution interface from its average bulk value. This feature affects the rates of attachment and detachment of…
It has been recently observed that plasmonic nanoantennas tuned to the Stokes wavelengths associated with the G and 2D Raman bands of graphene, rather than the laser pump, not only enhance Raman scattering in graphene but also displace and broaden the Raman spectra Ghamsari et al (2015 Phys. Rev. B 91 201408(R) ). Thi…
A neutral complex [Ni(L1)Cl2] (1) with trigonal bipyramidal geometry at Ni(II) was prepared by the reaction of NiCl2 with 2,6-bis(isopropylaminomethyl)pyridine (L1) in THF and then a mono-cationic complex [Ni(L1)Cl](BF4) (2) and di-cationic complex [Ni(L1)(CH3CN)3](BF4)2 (3) could be obtained by extracting one or two…
Background: Municipal solid waste incineration (MSWI) bottom ash contains a not insignificant amount of metallic aluminum, while circulating fluidized bed combustion (CFBC) fly ash is rich in active SiO2. Objective: To reduce the materials cost of autoclaved aerated concrete (AAC) production, these two types of solid…
A new paradigm of rheological characterization, oscillatory simple shear with infinite forcing amplitudes, is introduced by Khair (J. Fluid Mech., vol. 791, 2016, R5). This pushes the technique of large-amplitude oscillatory shear (LAOS) to have two extremely large amplitudes (both strain-rate and strain), which we mi…
The energetics of defects in the presence of domain walls in LiNbO 3 are characterized using density-functional theory calculations. Domain walls show stronger interactions with antisite defects than with interstitial defects or vacancies. As a result, antisite defects act as a strong pinning center for the domain wal…
The photocatalytic activity of an amorphous titanium oxide (a-TiOx) film was modified using a two-step deposition. The fluorinated base layer with a nano-textured surface prepared by a selective fluorination etching process acted as growth seeds in the subsequent a-TiOx deposition. A nanorod-like microstructure was ac…
We determine the momentum-dependent group velocities of ( ± 1,0) and (0, ± 1) Bloch-like surface plasmon polaritons (SPPs) in two-dimensional Au nanohole array by measuring their propagation lengths and decay lifetimes at different SPP propagation length via angle- and polarization-resolved reflectivity spectroscopy a…
Two new square pyramidal iron(III)-complexes of ‘salen’-type Schiff base ligands containing 4-substituted long alkoxy arms on the aromatic rings, [Fe(4-C16H33O)2salcn)]Cl and [Fe(4-C16H33O)2salophen)]Cl {salcn = N,Nʹ-cyclohexanebis(salicylideneiminato) and salophen = N,Nʹ-phenylenebis(salicylideneiminato)}, have been…
Point kernel integration (PKI) method is widely used in the visualization of radiation field in engineering applications because of the features of quickly dealing with large-scale complicated geometry space problems. But the traditional PKI programs have a lot of restrictions, such as complicated modeling, complicate…
This paper focuses on the elastic buckling strength of typical stiffened panels under bi-axial compression. Three levels of assumptions for stiffeners are investigated: (1) Vlasov assumption; (2) stiffeners’ web plate assumed deformable; (3) both stiffeners’ web and flange plates assumed deformable. The bi-axial buckl…
We present numerical studies of dipolar spin ice in the presence of a magnetic field slightly tilted away from the [111] axis. We find a first-order transition from a kagome ice to a $\mathbf{q}=X$ state when the external field is tilted toward the $[11\overline{2}]$ direction. This is consistent with the anomalous cr…
The charge density wave (CDW) state of α -U (called α 1 -U) was studied through a first-principles total-energy minimization using the conjugate gradient algorithm. The optimized crystal structure of α 1 -U was found to have the space group Pbnm , which was proposed in the earlier Landau-type theory and is isostructur…
The study was conducted to assess the textural quality of mozzarella cheese using MAP. 300 g of mozzarella cheese was placed in high barrier bags under five different atmospheres viz., air (atm 1), vacuum (atm 2), 100 % CO2 (atm 3), 100 % (atm 4) and a mixture of 50% N2 and 50% CO2 (atm 5). Periodically, the product w…
The performance, in thiophene HDS, of a CoMo/Al 2 O 3 catalyst was successfully improved through chemical modification of its oxidic precursor by impregnation with 1,5-pentanediol solution. The gas phase activation with a H 2 /H 2 S mixture was followed by thermogravimetric analysis coupled with a rapid chromatograph;…
Abstract This paper reviews the various data flows that occur in the generation and verification of optical proximity correction (OPC) for an optical lithography photomask. First we review the models that are or can be used in the OPC model-calibration flow, with some emphasis on those models that are not yet standard…
Abstract Micrometer-scale responses of radio-photoluminescence (RPL) glass dosimeters to focused ionized particle radiation were evaluated by combining ion-beam-induced luminescence (IBIL) and proton beam writing (PBW) using a 3 MeV focused proton microbeam. RPL phosphate glass dosimeters doped with ionic Ag or Cu act…
Magnetic torque measurements using a microcantilever have been performed to investigate the superconducting phase of ${\mathrm{Sr}}_{2}{\mathrm{RuO}}_{4}$ down to 40 mK. For high-quality single crystals with the transition temperature $({T}_{\mathrm{c}})$ of 1.48--1.49 K, an abrupt jump of the torque signal is found n…
We have studied an incipient ferroelectric BaZrO3 single crystal with perovskite structure by terahertz time-domain and Raman scattering spectroscopies. The phonon-polariton dispersion relation of the low-frequency infrared active TO1 and TO2 modes was studied from the real and imaginary parts of the complex dielectri…
This paper revisits a three-dimensional analytical approach to study internal instability in layered composites, when the behaviour of each component of the material is described by the three-dimensional equations of solid mechanics. It shows the development of a unified computational procedure for numerical realizati…
