INTRODUCTION: A major limitation of current liposomal cancer therapies is the inability of liposome therapeutics to penetrate throughout the entire tumor mass. This inhomogeneous distribution of liposome therapeutics within the tumor has been linked to treatment failure and drug resistance. Both liposome particle tran…
Abstract Co 3 O 4 samples have been deposited using RF-magnetron sputtering from an oxide target. In situ x-ray and ultraviolet photoelectron spectroscopy and x-ray diffraction have been carried out to identify the phase and composition of the films. The work function of films showed variation of about 1 eV depending…
Multidrug resistance (MDR) and targeted therapies present major challenges in tumor chemotherapy. Nanoparticles (NPs) hold promise for use in cancer theranostics due to their advantages in terms of tumor-targeted cytotoxicity and imaging. In this study, we developed N-((2-hydroxy-3-trimethylammonium) propyl) chitosan…
We introduce a “grafting-through” brush polymerization mechanism where monomers are supplied through the surface on which the initiators are attached rather than from solution as in the “grafting-from” technique. This is accomplished by attaching the initiator to the surface of a dialysis membrane and supplying monome…
High density of grain boundaries in solid materials generally leads to high strength because grain boundaries act as strong obstacles to dislocation activity. We find that the flexural strength of nanoporous gold of grain size 206 nm is 33.6% lower than that of grain size 238 μm. We prepared three gold-silver precurso…
The development of polymer nanocomposites by incorporating variable nanofillers has attracted attention of scientists, researchers and industrial sectors due to their dramatic improvement in various properties. Cellulose acetate (CA) based nanocomposites have interesting history in the field of medical applications be…
Inhibition of amyloid aggregation is important for developing potential therapeutic strategies of amyloid-related diseases. Herein, we report that the inhibition effect of a pristine peptide motif (KLVFF) can be significantly improved by introducing a terminal regulatory moiety (terpyridine). The molecular-level obser…
Exciton brightening in monolayer phosphorene is achieved via the dimensionality modification of excitons from quasi-1D to 0D. The luminescence quantum yield of 0D-like excitons is >33.6 times larger than that of quasi-1D free excitons. 2D phosphorene with quasi-1D free excitons and 0D-like excitons provides a unique p…
We present a simpler and novel design of a six-band terahertz perfect metamaterial absorber (MA) composed of a metal U-shaped closed-ring resonator, a dielectric spacer, and a metal back plate. The numerical simulation results demonstrate that it can perform absorption peaks at six resonant frequencies whose peaks ave…
All transparent conducting materials (TCMs) of technological practicality are n‐type; the inferior conductivity of p‐type TCMs has limited their adoption. In addition, many relatively high‐performing p‐type TCMs require synthesis temperatures >400 °C. Here, room‐temperature pulsed laser deposition of copper‐alloyed…
The novel Cr-containing low alloy steels have exhibited good corrosion resistance in CO2 environment, mainly owing to the formation of Cr-enriched corrosion film. In order to evaluate whether it is applicable to the CO2 and H2S coexistence conditions, the corrosion behavior of low-chromium steels in CO2-H2S environmen…
Nanomaterial interfaces and concomitant thermal resistances are generally considered as atomic-scale planes that scatter the fundamental energy carriers. Given that the nanoscale structural and chemical properties of solid interfaces can strongly influence this thermal boundary conductance, the ballistic and diffusive…
Magnetostrictive actuators featuring high energy densities, large strokes, and fast responses are playing an increasingly important role in micro/nano-positioning applications. However, such actuators with different input frequencies and mechanical loads exhibit complex dynamics and hysteretic behaviors, posing a grea…
Tailor-made polymers containing specific chemical functionalities have ushered in a number of emerging fields in polymer science. In most of these next-generation applications the focus of the community has centered upon closed-shell macromolecules. Conversely, macromolecules containing stable radical sites have been…
The study of the interaction of electron irradiation with matter and the response of the material to the passage of electrons is a very challenging problem. However, the growth mechanism observed during nanostructural evolution appears to be a broad and promising scientific field in nanotechnology. We report the in si…
Abstract Discontinuous modulation functions called crenel and saw-tooth have been developed for description and refinement of strongly modulated crystal structures with abrupt changes of modulation parameters. Although used for refinement of many modulated structures and mentioned in books on aperiodic crystals, techn…
BACKGROUND: The present study focuses on biodistribution profile and pharmacokinetic parameters of EGFR-targeted chitosan nanoparticles (TG CS nanoparticles) for siRNA/cisplatin combination therapy of lung cancer. MATERIAL & METHODS: Mad2 siRNA was encapsulated in EGFR targeted and nontargeted (NTG) CS nanoparticles b…
As one of the emerging new transition‐metal dichalcogenides materials, molybdenum ditelluride (α‐MoTe 2 ) is attracting much attention due to its optical and electrical properties. This study fabricates all‐2D MoTe 2 ‐based field effect transistors (FETs) on glass, using thin hexagonal boron nitride and thin graphene…
High Resolution Image Download MS PowerPoint Slide We report the fine-tuning of the localized surface plasmon resonances (LSPRs) from ultraviolet to near-infrared by nanoengineering the metal nanoparticle morphologies from solid Ag nanocubes to hollow AuAg nanoboxes and AuAg nanoframes. Spatially resolved mapping of p…
Lipid-core nanocapsules (LNC) are formed by an organogel surrounded by poly(epsilon-caprolactone) and stabilized by polysorbate 80. LNCs increase the concentration of drugs in the brain after oral or intravenous administration. We proposed to determine whether the drug is released from the LNC to cross the blood brain…
