Synthesis of waterborne polyurethane–silver nanoparticle

2017/11/8Waterborne polyurethane antibacterial coating (WPU-Ag-1%) was obtained by adding 0.2 g silver nanoparticle dispersion (1 wt%) and 0.02 g thickening agent into 20 g waterborne polyurethane. The mixture was cast onto synthetic leather by vacuum spin coater, then the coated synthetic leather (synthetic leather-WPU-Ag-1%) was dried at 70C for 30 min, having thickness of about 25.6 μm.

The mirror chips are coated with a high reflectivity, multilayer dielectric coating (Advanced Thin Films, target transmission of 15 ppm). A single cavity, exhibiting sufficiently high finesse, is pumped with 25 mW at a wavelength of 1547 nm (Toptica CTL-1550) to excite a TEM 00 mode, and the laser frequency is stabilized to the cavity resonance via side-of-fringe locking using the back

We observe an influence of the particle coating on the growth behavior with respect to the cytotoxic properties of the coating agent and its reactive group. The impact on surfactant-induced cell behavior was investigated in more detail by interface-sensitive impedance spectroscopy (electric cell–substrate impedance sensing, ECIS).


Although many routes have been developed to link together colloidal particles into controlled superstructures from dimers all the way up to three-dimensional lattices, they generally depend on coating the nanoparticle surfaces in specific ways to control the way they link up. By contrast, Yi et al. developed a ligand chemistry such that, when two particles link together, it changes the

Polyethylene glycol functionalized gold nanoparticles: the

2011/4/27Thiol-terminated polyethylene glycol (PEG) is commonly used to functionalize the surface of gold nanoparticles (AuNPs) in order to improve their in vivo stability and to avoid uptake by the reticular endothelial system. Although it has been reported that AuNPs functionalized with tethered PEG are stable in biological media, the influence of chain density remains unclear. This study

Polymer nanocomposites for electrical energy storage

INTRODUCTION Advances in portable electronic devices, stationary power systems, and hybrid electric vehicles create demand for low‐cost, compact, and high‐performance electrical energy storage devices. 1, 2 Among various energy storage technologies including batteries, fuel cells, capacitors, and supercapacitors, capacitors possess the advantage of high power density due to the fast


High permittivity and breakdown strength are desired to improve the energy storage density of dielectric materials based on reinforced polymer composites. This article presents the synthesis of polythiophene-encapsulated BaTiO 3 (BTO-PTh) nanoparticles via an in situ Cu(II)-catalyzed chemical oxidative polymerization of thiophene monomer on hydrothermally obtained tetragonal BTO nanocrystals.

Gold nanoparticles for cancer radiotherapy: a review

Amongst the available nanoparticle systems, gold nanoparticles have become particularly popular due to several advantages: biocompatibility, well-established methods for synthesis in a wide range of sizes, and the possibility of coating of their surface with a

Iron Oxide Nanoparticle Coatings Dictate Cell Outcomes

A critical issue in nanomedicine is to understand the complex dynamics that dictate the interactions of nanoparticles (NPs) with their biological milieu. The most exposed part of a nanoparticle is its surface coating, which comes into contact with the biological medium and adsorbs proteins, forming what is known as a protein corona (PC). It is assumed that this PC mainly dictates the

1. Introduction

Since the individual permittivity of TiO 2 is greater than that of the polymer, the latter will have an influence on the permittivity obtained for the nano- and microcomposites. SEM assessment of the morphology of the nano- and microcomposites structure shows a uniform dispersal of nano- and microparticles in the polymer, confirming the efficiency of the synthesis of these materials process


Defects are deleterious for optical coatings. Long-range nanoparticle ordering is needed to achieve high-density nanoparticle packing; the density of the final nanoparticle coatings approaches that of the bulk materials. In situ grazing incidence small-angle scattering (GISAXS) characterization has been performed to evaluate and monitor nanoparticle self-assembly during the coating process and

Disruption of brain conductivity and permittivity and

As one of the most exonerative, competitive, and abundant nanoparticles in curative uses, silver nanoparticles (AgNPs) play a growing important role in developing global neurodegeneration. Herein, we inspected the neurotoxic and histopathological effects of the oral dose of 26.9 nm citrate-coated AgNPs (100 and 1000 mg/kgbw, 28 days) on the brain conductivity and permittivity combined with

The Effect of Nanoparticle Size, Shape, and Surface

An understanding of the interactions between nanoparticles and biological systems is of significant interest. Studies aimed at correlating the properties of nanomaterials such as size, shape, chemical functionality, surface charge, and composition with biomolecular signaling, biological kinetics, transportation, and toxicity in both cell culture and animal experiments are under way. These

A nanoparticle or ultrafine particle is usually defined as a particle of matter that is between 1 and 100 nanometres (nm) in diameter. The term is sometimes used for larger particles, up to 500 nm, [citation needed] or fibers and tubes that are less than 100 nm in only two directions.

2019/4/2Here we show that nonlocality in the metallic response affects surface plasmons propagating at the interface between a metal and a dielectric with high permittivity. As a direct consequence, any nanoparticle with a radius larger than 20 nm can be expected to be sensitive to spatial dispersion whatever its size.
