Cancer stem cells (CSCs) are thought to be responsible for the relapse of multiple myeloma (MM). The objective of this study was to target therapy of MM cancer stem cells using gamma-Fe2O3@DMSA magnetic nanoparticle combination with paclitaxel and anti-ABCG2 monoclonal antibody, and to evaluate the combined therapeuti…
We study the supercritical instability in gapped graphene with two charged impurities separated by distance $R$ using the two-dimensional Dirac equation for electron quasiparticles. Attention is paid to a situation when charges of impurities are subcritical, whereas their total charge exceeds a critical one. The criti…
The inherent properties of epitaxial oxide thin-film layers have attracted the intense interest of different research fields, such as catalysis and microelectronics. The focus of this work is the temperature-dependent oxygen release, oxygen vacancy formation, and lattice rearrangement of Ce 1– x Pr x O 2−δ thin films…
Lipid coating is a method highly used to improve the biocompatibility of nanoparticles (NPs), even though its effect on the NP properties is still object of investigation. Herein, silica NPs containing methylene blue, which is a photosensitizer used in a variety of biomedical applications, were coated with a phospholi…
Versatile ZnO nanostructures have been fabricated by a two‐step hydrothermal method. Controllable growth of ZnO is feasible by using different kinds of zinc sources. It is revealed by scanning electron microscopy that ZnO nanorods with average diameter 155 nm were synthesized by using Zn(CH 3 COO) 2 as the zinc source…
Organophosphate pesticides are applied widely in the world for agricultural purposes, and their exposures often resulted in non-cocooning of Bombyx mori in China. TiO2 nanoparticles have been demonstrated to increase pesticide resistance of Bombyx mori. While the toxicity of phoxim is well-documented, very limited inf…
Nanoclusters of noble metals like Ag and Au have attracted great attention as they form a missing link between isolated metal atoms and nanoparticles. Their particular properties like luminescence in the visible range and nontoxicity make them attractive for bioimaging and biolabelling purposes, especially with use of…
The possibility of forming quantum wells (QWs) in transition-metal dichalcogenide nanosheet assembled superlattices (SLs) was investigated by using the first principles calculations. The interfacial binding energies and electronic structures of MoS2/MX2 (MX2 = MoSe2, WS2, and WSe2) SLs were calculated. The interfacial…
Coupling therapeutic proteins to targeted nanocarriers can enhance their biodistribution. This is the case for enzyme replacement therapies where intravenously injected enzymes must avoid prolonged blood exposure while reaching body organs. We have shown enhanced tissue targeting of various lysosomal enzymes by coupli…
SiO2 films were deposited on fused silica, silicon, glass, germanium, and sapphire substrates by an ion beam sputtering technique. The optical properties of SiO2 films on different substrates and interfacial layer properties between SiO2 films and different substrates were researched by the spectroscopic ellipsometry…
Gold nanoparticles (AuNPs) exhibit unique properties that have made them a very attractive material for application in biological assays. Given the potentially interesting interactions between AuNPs and biological macromolecules, we investigated AuNPs-induced protein crystal growth. Differently functionalized AuNPs we…
A propylene/ethylene polymeric matrix was reinforced by the simultaneous addition of a β-nucleating agent (calcium pimelate) and multi-walled carbon nanotubes (MWCNTs) in various concentrations. The present manuscript explores the competitive crystallization tendency that is caused by the presence of the two fillers.…
Symmetry breaking perturbations in an electronically conducting medium are known to produce Friedel oscillations in various physical quantities of an otherwise pristine material. Here we show in a mathematically transparent fashion that Friedel oscillations in graphene have a strong sublattice asymmetry. As a result,…
We consider the structure transitions in oblate supramicrometer nematic droplets related to reorientation of the line defect in the electric field. These transitions can be used in optical devices based on polymer dispersed liquid crystal materials with high contrast ratio. We suggest a simple method for determination…
While antibiotic resistance in bacteria is rapidly increasing, the development of new antibiotics has decreased in recent years. Antivirulence drugs disarming rather than killing pathogens have been proposed to alleviate the problem of resistance inherent to existing biocidal antibiotics. Here, we report a nontoxic bi…
Ceramics in the system 0.45 Ba 0.8 Ca 0.2 TiO 3 –(0.55− x ) Bi ( Mg 0.5 Ti 0.5 ) O 3 – x NaNbO 3 , x = 0–0.02 were fabricated by a conventional solid‐state reaction route. X‐ray powder diffraction indicated cubic or pseudocubic symmetry for all samples. The parent 0.45 Ba 0.8 Ca 0.2 TiO 3 –0.55 Bi ( Mg 0.5 Ti 0.5 ) O…
A comparative morphological study of different ZnO nanostructures was carried out with different varying process parameters for energy harvesting. Molarity, temperature, growth duration and seed layer were such fundamental controlling parameters. The study brings out an outstanding piezoelectric coefficient (d(33)) of…
The reaction of 2-hydroxybenzophenone derivatives with europium ions has afforded a new family of luminescent nonanuclear Eu(III) clusters. Crystal structure analysis of the clusters reveals that the metal core comprises two vertex-sharing square pyramidal units. Most of these complexes show emissions typical of Eu(3+…
Polymer-clay nanocomposites are highly sought-after materials, mainly due to their applicability in a variety of avenues. From the standpoint of the preparation of these nanocomposites, however, organic compatibility with clay and adherence to “green chemistry” concepts and principles can be limiting factors. As such,…
In the system La – Cr – O , there are three ternary oxides ( LaCrO 4 , La 2 Cr 3 O 12 , and La 2 CrO 6 ) that contain Cr in higher valence states (V or VI). On heating, LaCrO 4 decomposes to LaCrO 3 , La 2 Cr 3 O 12 to a mixture of LaCrO 4 and Cr 2 O 3 , and La 2 CrO 6 to LaCrO 3 and La 2 O 3 with loss of oxygen. The…
