The atomic layer deposition (ALD) method was applied to grow thin polycrystalline BiFeO3 (BFO) films on Pt/SiO2/Si substrates. The 50 nm thick films were found to exhibit high resistivity, good morphological integrity, and homogeneity achieved by the applied ALD technique. Magnetic characterization revealed saturated…
A method for supporting palladium nanoparticles on magnetically separable organosilica nanoparticles functionalized with ionic liquid groups is described. The system was prepared by sol–gel condensation of two silica precursors: tetraethyl orthosilicate (TEOS) and bis-silylated ionic liquid monomer, on hydrophobic mag…
The Ag-based delafossite transparent conducting oxides are potential p-type materials for transparent electronics. However, they have attracted less attention due to their difficult synthetic chemistry and relatively low conductivity.
Abstract A design mode, in which a casing is filled with a charge initiated off‐centre (eccentric point initiation), is common in the field of explosion and structural protection. The fragment velocity distribution along the circumference of the casing is distinctly non‐uniform due to the difference in blast loading a…
Interaction of carbonate surfaces with water plays a crucial role in carbonate nucleation and crystal growth. This study provides experimental evidence for the existence of two different types of water having distinct energetics in amorphous carbonates, MCO 3 (M = Ca, Mn, and Mg). The adsorption enthalpy curves obtain…
Biodegradable and pH-sensitive graft copolymers based on polysuccinimide (PSI) were synthesized as intracellular drug carriers. Hydrophobic octadecylamine (C18) and hydrophilic O-(2-aminoethyl) polyethylene glycol (PEG, Mw 5000) were grafted on a PSI backbone for amphiphilicity, enabling the formation of a self-assemb…
The room temperature carrier mobility in atomically thin 2D materials is usually far below the intrinsic limit imposed by phonon scattering as a result of scattering by remote charged impurities in its environment. We simulate the charged impurity-limited carrier mobility μ in bare and encapsulated monolayer phosphore…
This research presents a simple and efficient method to synthesize porous nitrogen-doped carbon microspheres (PNCM) by the carbonization of microporous poly(terephthalaldehyde-pyrrole) organic frameworks (PtpOF). The common KOH activation process is used to tune the porous texture of the PNCM and produce an activated-…
The purpose of this study was to determine the effect of PEGylation on the interaction of poly(amidoamine) (PAMAM) dendrimer nanocarriers (DNCs) with in vitro and in vivo models of the pulmonary epithelium. Generation-3 PAMAM dendrimers with varying surface densities of PEG 1000 Da were synthesized and characterized.…
The covalent functionalization of graphene oxide (GO) with bis(3-aminopropyl)-terminated poly(ethylene glycol) (NH 2 –PEG–NH 2 ) and subsequent grafting with maleic anhydride grafted polypropylene (MAPP) oligomer matrix using reactive compatibilization were carefully analyzed and verified through detailed investigatio…
Magnetic properties and magnetocaloric effect (MCE) of intermetallic HoNiSi compound have been investigated systematically. It is found that HoNiSi exhibits antiferromagnetic (AFM) state below the Néel temperature TN of 3.8 K, which is quite close to the liquid helium temperature (4 K). A giant MCE without hysteresis…
A HA-EDA–Pt( <sc>iv</sc> ) nanoconjugate achieved tumor-targeted therapy <italic>via</italic> multiple steps, such as EPR effect, receptor-mediated endocytosis and microenvironment-based drug release and reactivation.
A complete phase diagram and its corresponding physical properties are essential prerequisites to understand the underlying mechanism of iron-based superconductivity. For the structurally simplest 11 (FeSeTe) system, earlier attempts using bulk samples have not been able to do so due to the fabrication difficulties. H…
The conditions to make nanorods functionalized fabric superhydrophobic have been optimized to obtain three kinds of self-cleaning characteristics such as physical, chemical, and biological. Physical self-cleaning is the lotus effect which is characterized by measuring both water contact and sliding angles. Chemical se…
The poor kinetics of hydrogen evolution and the irreversibility of the hydrogen discharge hamper the use of transition metal borohydrides as hydrogen storage materials, and the drawbacks of current synthetic methods obstruct the exploration of these systems. A wet-chemistry approach, which is based on solvent-mediated…
A 2D mesoporous carbon/graphene nanocomposite shows a very high power density of 135 kW kg <sup>−1</sup> at an energy density of 60 W h kg <sup>−1</sup> .
Two-photon photodynamic therapy (2P-PDT) is a promising noninvasive treatment of cancers and other diseases with three-dimensional selectivity and deep penetration. However, clinical applications of 2P-PDT are limited by small two-photon absorption (TPA) cross sections of traditional photosensitizers. The development…
Bulk silicon is a poor light emitter and absorber, but its optical properties are significantly enhanced by nanostructuring. We use first-principles calculations to investigate the electronic and optical properties of nanoporous silicon. We determine and analyze the electronic structure, optical coefficients, and phot…
A correlation between graphene domains grown on the outer and the inner surfaces of Cu pockets is found, which discloses a new graphene growth mechanism based on the fast diffusion of carbon atoms through the 25 micro-meter-thick Cu foil, confirmed by isotopic labeling. Subsequently, on the outer surface of the Cu poc…
Two grades of polyvinyl alcohol (PVA) namely partially hydrolyzed (designated as PVA-I) and fully hydrolyzed (designated as PVA-II) were studied with the aim of determining the influence of PVA degree of hydrolysis on the corrosion inhibition effect of mild steel in HCl medium. The investigation was carried out using…
