"This book provides a comprehensive coverage on nanobioceramics and their potential applications in healthcare. Ground-breaking new discoveries in bioceramics and their properties have meant an increasing interest in the development of how this can be related to nanobiomaterials, and in treating various conditions fro…
Particle Impact Drilling (PID) is a novel method to improve the rate of penetration (ROP). In order to further improve the performance of PID, an investigation into the effect of single and double particles: (1) diameter; (2) initial velocity; (3) distance; and (4) angle of incidence was undertaken to investigate thei…
The solidified microstructures of metal alloys are produced by the process of crystal growth. However, some processes of crystal growth may remain uncovered because the solidification of metal alloys usually happens at high temperature with tiny growth scale and high growth speed. In the current work, based on the sol…
Surface deposited layers of mesoporous silica particles could function as support for bio-sensing or drug release applications. It is crucial to control the surface deposition process and employ relevant techniques to characterize the properties of the particles on the surface. Here, we deposit SBA-15 particles on nat…
There is a critical need to improve the accuracy of drug screening and testing through the development of in vitro culture systems that more effectively mimic the in vivo environment. Surface topographical features on the nanoscale level, in short nanotopography, effect the cell growth patterns, and hence affect cell…
The interactions between temozolomide and chloroquine were examined via Dispersion‐Corrected Density Functional Theory and MP2 methods. Chloroquine was considered in both its lowest energy structure and in a local minimum where its aromatic system and secondary amine group are free to interact directly with temozolomi…
In spite of the current prevalence of the CVD-based processes, the electric arc remains an interesting process for the synthesis of carbon nanoforms, thanks to its versatility, robustness and easiness. It also allows performing in-situ substitution of carbon atoms by hetero-elements in the graphene lattice. Our work a…
We model the low energy dynamics of graphene in the continuum in terms of a version of reduced quantum electrodynamics (QED) restricting fermions to a [Formula: see text]-dimensional brane, while photons remain within the [Formula: see text]-dimensional bulk. For charge carriers, besides the Dirac mass gap, we conside…
We studied the structural and electronic properties of pentaerythritol tetranitrate (PETN) and erythritol tetranitrate (ETN) crystals within the framework of density functional theory with van der Waals interactions. The computed lattice parameters have good agreement with experimental data. Electronic and structural…
Abstract A significant enhancement of the yttrium‐stabilized zirconia‐supported palladium (0.2 wt % Pd/YSZ) catalytic activity for the total oxidation of methane was achieved in a dual‐bed system by the association of LaMnO 3 +Pd/YSZ materials. The combination with the best performance was 40 wt % LaMnO 3 +60 wt % Pd/…
Stacking of the metal complex [(5,6-dimethyl-1,10-phenanthroline)(1S,2S-diaminocyclohexane)platinum(ii)]2+ (56MESS) onto the surface of two different fullerenes, a carbon nanotube (CNT), and a C60-buckyball was examined. The metal complex forms a supramolecular complex with multi-walled CNTs but not with buckyballs. B…
We report a dynamic structure and band engineering strategy with experimental protocols to induce indirect-to-direct band gap transitions and coherently oscillating pure spin-currents in three-dimensional antiferromagnets (AFM) using selective phononic excitations. In the Mott insulator LaTiO3, we show that a photo-in…
We have performed density functional calculations of the vibrational and thermodynamic properties of the ternary antimonides TiXSb, ZrXSb and HfXSb (X = Si, Ge). The direct method is used to calculate the phonon dispersion relation and phonon density of states for these compounds as well as their infrared and Raman ac…
In this study, dense arrays of aligned carbon nanotubes are obtained by thermal catalytic chemical vapor deposition, using Fe catalyst dispersed on a thin Ta layer. Alignment of the carbon nanotubes depends on the original Fe layer thickness from which the catalyst dispersion is obtained by thermal treatment prior to…
The buried interface between a molecular thin film and the metal substrate is generally not accessible to the photoemission experiment. With the example of a sexiphenyl ($6\mathrm{P}$) bilayer on Cu we show that photoemission tomography can be used to study the electronic level alignment and geometric structure, where…
Black phosphorus has emerged as a promising two-dimensional semiconductor, which has a unique structure that is anisotropic in-plane. This structural anisotropy translates to some very interesting orientation dependent properties. In this paper we present directional characterization and analysis of the phonon and ele…
In this work, a convenient method to enhance the photoluminescence (PL) of single-walled carbon nanotubes (SWNTs) in aqueous solutions is provided. Dispersing by single-stranded DNA (ssDNA) and modifying with gold nanoparticles (AuNPs), about tenfold PL enhancement of the SWNTs is observed. More importantly, the selec…
The plasmonic property of Ag patchy particles fabricated using a colloid monolayer and oblique angle deposition shows significant variations due to the multidomain nature of the monolayer. A swinging oblique angle deposition method is proposed to create uniform patchy particles. Both numerical calculations and experim…
We investigate the magnetic ordering and the magnetization dynamics (from kHz to THz time scales) of the double perovskite ${\mathrm{Lu}}_{2}{\mathrm{MnCoO}}_{6}$ using elastic neutron diffraction, muon spin relaxation, and micro-Hall magnetization measurements. This compound is known to be a type II multiferroic with…
One of the greatest challenges with single-walled carbon nanotube (SWNT) photovoltaics and nanostructured devices is maintaining the nanotubes in their pristine state (i.e., devoid of aggregation and inhomogeneous doping) so that their unique spectroscopic and transport characteristics are preserved. To this effect, w…
