The formation of aggregates in simplified industrial styrene-butadiene nanocomposites with silica filler has been studied using a recent model based on a combination of electron microscopy, computer simulations, and small-angle X-ray scattering. The influence of the chain mass (40 to 280 kg mol(-1), PI < 1.1), which s…
In this paper, the synthesis of Ag microflowers for use as manipulable and reusable substrates in surface enhanced Raman spectroscopy (SERS) is demonstrated, working with ultra-low volumes of the analyte. Flower-like AgBr crystallites with a growth direction of 〈110〉 were first obtained by thermolysing a complex obtai…
Water-soluble fluorescent silver nanoclusters (AgNCs) with almost seven and nine silver atoms and a quantum yield (QY) of 5.38 ± 0.25% were successfully prepared via one-pot hydrothermal synthesis using polymethacrylic acid sodium salt (PMAA-Na) as a template. The as-prepared PMAA-AgNCs displayed a mono-distribution,…
A novel reduction-sensitive pullulan-based biocompatible material can self-assemble into nanomicelles and release loaded drug triggered by reductive condition.
Self-healing is the ability of a material to repair mechanical damage. The lifetime of a coating or film might be lengthened with this capacity. Water enabled self-healing of polyelectrolyte multilayers has been reported, using systems that grow via the interdiffusion of polyelectrolyte chains. Due to high mobility of…
A simplified, single-step aqueous synthesis route to tunable anisotropic silver nanocrystals (NCs) has been developed by tailoring the hydrogen-bonding interactions between a mild stabilizer, sodium citrate, and a mild reductant, hydrazine hydrate. The structure directing ability of the H-bonding interaction was harne…
The thermodynamics of xyloglucan adsorption to montmorillonite clay in water was studied with molecular dynamics simulations.
The photoluminescence intensity of Bi-doped Y <sub>2</sub> O <sub>3</sub> is increased in a high oxygen partial pressure atmosphere due to the healed oxygen vacancy.
The thermal behavior, decomposition kinetics and mechanisms of 1-amino-1-(tetrazol-5-yldiazenyl) guanidine (tetrazene) and 2-(tetrazol-5-yldiazenyl) guanidine (MTX-1) have been investigated using DSC, TG techniques, and quantum chemical calculations. It has been found that MTX-1 is much more stable than tetrazene and…
The capability of bio-sourced plasticizers epoxidized palm oil (EPO) and epoxidized soybean oil (ESO) in toughening and aiding the melt-processing of PLA were investigated. At various loadings, they were melt-compounded with PLA and hot pressed into 3-mm sheets for impact strength testing. From the torque and stock te…
Synthetic methods are reported to transcribe complex characteristics of biological systems into organic materials with an unprecedented level of sophistication.
The present study explores the development of mesostructured bioelectrochemical interfaces with accurate compositional and topological control of the supramolecular architecture through the layer-by-layer assembly of ternary systems based on poly(allylamine) containing an osmium polypyridyl complex (OsPA), an anionic…
A novel type of phthalocyanine pentad containing four boron dipyrromethene (BODIPY) units at peripheral positions of the phthalocyanine framework has been designed and synthesized for the first time. The Sonogashira coupling reaction between 4,4'-difluoro-8-(4-ethynyl)-phenyl-1,3,5,7-tetramethyl-4-bora-3a,4a-diaza-s-i…
In the current study, CdS/ZnS core–shell nanoparticles were successfully synthesized from CdSO4·8H2O and Zn(NO3)2·6H2O starting reagents in the presence of ultrasonic irradiation. The effects of preparation parameters such as ultrasonic power, irradiation time, and precursor concentration on the morphology of the CdS/…
In order to overcome the serious deficiencies of the traditional aqueous centrifugation method in on-demand purification of metal nanoparticles, we have theoretically and experimentally developed a simple purification method based on the nanoparticles' surface area discrepancy, which can separate particles with the sa…
Tunable band gaps of Co <sub>3−x</sub> Cu <sub>x</sub> O <sub>4</sub> nanorods were synthesized with a solution process and first reported in this study.
The Pd decoration on graphene oxides effectively modifies the structural and electronic properties of nanomaterials and improves the adsorption of nitrogen oxides.
We grow AB2 random hyperbranched polymer structures in different ways and using different simulation methods. In particular we use a method of ad hoc construction of the connectivity matrix and the bond fluctuation model on a 3D lattice. We show that hyperbranched polymers split into two universality classes depending…
Redox-active porous organic polymers (POPs) have enormous potential in applications ranging from electrocatalysis to solar energy conversion.
The electronic properties of MoSe <sub>2</sub> can be modified by manipulating its interaction with metal electrodes using a self-assembled monolayer of polar molecules.
