In this paper, we demonstrate a template-free, site-specific, and scalable electrochemical method for the fabrication of individually addressable polyaniline nanoframework electrode junctions in parallel-oriented array. These nanoframeworks, which are composed numerous intercrossing nanowires that have uniform diameters ranging from 40 to 80 nm, can be used chemical sensing HCl NH3 gases ethanol vapor pH aqueous NaCl solutions.
Rattle-structured nanoparticles with movable cores, porous shells and hollow interiors have shown great effectiveness in drug delivery cancer theranostics.Targeting autophagy glucose provided alternative strategies for intervention therapy.Herein, rattle-structured polydopamine@mesoporous silica were prepared vivo photoacoustic (PA) imaging augmented low-temperature photothermal therapy (PTT) via complementary inhibition metabolism.Methods: The multifunctional designed the nanocore of PDA...
The drying of thin nanocrystal solution films creates a varied range structured aggregate spatial patterns as function surface coverage. These images can be understood predicted kinetic stages in the fluid-fluid spinodal phase separation 2D van der Waals particle system. It is suggested that occurs due to increased nanocrystal−nanocrystal interaction presence air, compared with shielded organic solvents.
Dendritic gold (Au) nanoparticles have been successfully synthesized by the one-step hydrothermal reduction of HAuCl4·4H2O using ammonium formate (AF) as a reducing agent in presence PVP. Effects different reactant concentrations on morphologies obtained products systematically investigated. On basis observed transmission electron microscopy (TEM) and scanning (SEM), it has found that an excessive number AF molecules are origin dendritic Au particles besides PVP stabilizer. serve not only...
The environmental impact of corrosion is very dangerous and consumes much world’s efforts funds. This work discusses the safeguarding environment, metals, metal-infra structures by efficient Schiff’s base inhibitors. inhibitors [(1E,3E)-N1,N3-dibutyl-1-(thiophen-2-yl)butane-1,3-diimine] (GSB-I) [(1Z,3Z)-N1,N3-bis(4-methylhexan-2-yl)-1-(thiophen-2-yl)butane-1,3-diimine] (GSB-II) were successfully synthesized evaluated for protection API 5L X65 steel (CS) in 1 M HCl media using electrochemical...
A method for the spatially selective biofunctionalization of silicon micro- and nanostructures is reported, results are presented both single-crystal (111) or (100) surfaces. An electroactive monolayer hydroquinone was formed on surface H-terminated working electrodes via an olefin reaction with UV-generated radicals. Molecules presenting either cyclopentadiene a thiol group can be immobilized onto regions where has been oxidized. Molecular size crystal orientation evaluated as important...
For bimetallic nanoparticles (NPs), the degree of alloying is beginning to be recognized as a significant factor affecting NP properties. Here, we report an alloyed crystalline Au-Ag hollow nanostructure that exhibits high catalytic performance, well structural and chemical stability. The porous nanoshell structures (HPNSs) with different morphologies subnanoscale were synthesized by adjusting size sacrificial Ag NPs via galvanic replacement reaction. activities nanomaterials evaluated model...
The self-assembly of 12 nm PbSe nanocrystals on a graphite surface during solvent evaporation is analyzed within the two-dimensional van der Waals phase condensation model. interparticle attractive force, separation kinetics, and critical coverage in this system can be revealed from aggregation spatial patterns at different kinetic stages. Cracking nanocrystal monolayer drying high reveals limitations
In this work, we develop a facile one-step strategy for rapidly (within 1 min) preparing four kinds of nitrogen doped carbon dots (N-CDs) and construct label free sensor array protein discrimination. The monodispersed blue emitting N-CDs, with quantum yield (QY) about 7.6% (calibrated quinine sulfate as the reference), were systematically characterized by using fluorescence spectroscopy, atomic force microscopy (AFM), dynamic light scattering (DLS), X-ray photoelectron spectroscopy (XPS)...
The coordination of valeric acid (VA), glutaric (GA), and tricarballylic (TA) with Fe–OH on the Fe3O4 nanoparticle surface has been systematically studied to elucidate effects COOH, molecular configuration, ligand concentration by combined use attenuated total reflectance Fourier transform infrared (ATR-FTIR) thermogravimetric analysis (TGA). results show that binding ability acids increases increase in COOH number. Multiple conformations coexist for dicarboxylic tricarboxylic coordinated...
Porous hematite (α-Fe2O3) with branched nanostructures such as V and Y shapes were prepared through dehydration of goethite (α-FeOOH) precursor, while α-FeOOH are self-organized by straight nanorods via facet-mediated oriented attachment mechanism at high pH without the use organic additives. This novel approach is different from mechanisms reported for other α-Fe2O3 anisotropic structures. Based on combined TEM, high-resolution TEM AFM analyses, a possible formation was suggested. A...
Abstract Due to their unique optical properties and facile processability, nanorods of noble metals are promising for highly effective nanoscale devices. Specifically, the local electric field enhancement brought about by plasmon coupling between in an array configuration shows great potential sensing. Recent results demonstrate that vertical arrays metal nanorods, used as substrates surface enhanced Raman scattering, can achieve sensitivity levels required presymptomatic detection....
