Localized protonation of 4-mercaptopyridine (4-MPY), activated by light in the presence of silver nanoparticles is monitored under ambient conditions using surface-enhanced Raman scattering (SERS) and tip-enhanced Raman scattering (TERS). The reaction can be controlled by the excitation wavelength and the atmospheric…
Objective. The reinforcement effect of polymer-grade montmorillonite (PGV and PGN nanoclay) on Fuji-IX glass ionomer cement was investigated. Materials and Method. PGV and PGV nanoclays (2.0 wt%) were dispersed in the liquid portion of Fuji-IX. Fourier-transform infrared (FTIR) spectroscopy and gel permeation chromato…
Novel mono- and ball-type Co(ii), Zn(ii) and Cu(ii) metallophthalocyanines (MPcs) were synthesized from 1,1'-p-anisylidenbis(2-naphthoxyphthalonitrile). The MPcs have been characterized by elemental analysis, UV/Vis, IR and (1)H-NMR spectroscopy and MALDI-TOF mass spectrometry. The performances of organic field effect…
The ability of filtration and separation media containing fibres to remove impurities from oil, water, and blood can be enhanced using magnetic fields. The ability to regulate the dielectric and magnetic behaviour of fibrous webs in terms of superparamagnetic or ferromagnetic properties by adjusting material compositi…
During the last few decades, the photoswitching of spin crossover compounds, based on the Light-Induced Excited Spin State Trapping (LIESST) effect, has been widely studied. More recently, the synthesis and characterization of spin crossover nanoparticles have been developed. This focused review describes the recent p…
In this study, effects of surface modification of calcium carbonate (CaCO3) nanoparticles with a single-layer of stearic acid were investigated on dispersion in polypropylene (PP) matrix. Two kinds of CaCO3 nanoparticles (monolayer-coated and uncoated) were used to investigate this effect. All combinations were mixed…
In this research, the polarization behavior and kinetic pathways of an SOFC cathode have been investigated with a 1-D continuum model incorporating material physical properties and surface potential effects into a multi-step ORR kinetic formalism. It is found that (1) Two different types of 3PB-to-2PB pathway transiti…
Herein, we assessed the potential toxicities of different bimetallic Fe nanoparticles (Fe/Pd, Fe/Cu, Fe/Ni, and Fe/Pt) toward E. coli and compared them with that of unmodified Fe. The results showed that Fe/Cu was the most toxic followed by Fe, Fe/Ni, Fe/Pt, and Fe/Pd nanoparticles in descending order.
Herein, adsorption and removal of 1-naphthol from water using reduced graphene oxide (rGO) is reported.
Owing to the very different electrovalences of indium and silver, nanoparticles made of these elements are among the simplest examples of hybrid plasmonic systems retaining a full metallic character. The optical properties of small indium-silver clusters are investigated here for the first time in relation to their st…
Structural templating of organic semiconductors affords control of out-of-plane film structure and molecular orientation with respect to solid surfaces.
Ordered mesoporous γ-Al 2 O 3 with high thermal stability and low-level residual chlorine is obtained by optimizing sol–gel parameters and silicon content.
Two hexanuclear [Ni 2 Ln 4 ] aggregates exhibit either an enhanced magnetocaloric effect or slow magnetic relaxation, depending on the lanthanide ions chose.
Highly selective and sensitive detection of pepsin was developed through peptic hydrolysis of lysozyme-stabilized gold nanoclusters at pH 3.
A facile and versatile method to synthesize amphiphilic polysulfone-poly(ethylene glycol) block copolymers has been successfully developed via a macromolecular transetherification reaction at room temperature.
A spongy graphene paper with an inside foldable corrugated structure is fabricated by electrothermal reduction of the oxygen-containing groups inside an RGO paper. Reversible macroscopical length contraction of the spongy graphene paper with a strain of 2.4% under 10 V voltage is exhibited, mostly attributed to the de…
Chitin and chitosan were produced from the structures of the resting eggs of Ceriodaphnia quadrangula (Müller, 1785), of which tons are naturally produced in a dammed lake. On a dry weight basis, |$16{\rm{ - }}17\% $| chitin and |$11\% $| chitosan were extracted from the resting egg structures. The degree of deacetyla…
In situ Electrochemical Quartz Microbalance with Dissipation (EQCM-D) was employed to investigate the initial stage of solid electrolyte interphase (SEI) layer formation on bare aluminum electrodes and cathode-coated Al electrodes for lithium-ion battery (LIB) applications. EQCM reveals the SEI layer forms spontaneous…
We report a simple and straight forward approach for the synthesis of Cu-Ni graphene hybrid nano-composites. These nano-composites have been characterized using AFM, XRD, FTIR spectroscopy and HRTEM. The characterization data clearly shows uniform decoration of Cu-Ni nanoparticles on graphene layers. A thin film of th…
Two novel quadrupolar D–π–D type two-photon absorption (2PA) luminophores PA2F4H8E8 and AnA2F4H8E8 were synthesized by Wittig–Horner reaction in high yields. By using distyrylbenzene as the π-bridge center, PA2F4H8E8 shows two-photon absorption aggregation-induced emission enhancement (2PA-AIEE) and exhibits exception…
