-modes of the AgCl-Ag waveguide. The interference pattern determines the grating constant of the resulting spontaneous periodic nanostructures. Also, our studies indicate a strong dependence of the shape and size distribution of the formed Ag nano-coalescences on the wavelength of the incident beam. It also influences…
Fluorescent conjugated materials exhibiting reasonable biocompatibility that are capable of interacting with biological molecules are of interest for bio-sensing and imaging applications. Traditional approaches do not allow for the synthesis of conjugated materials in the presence of biologically relevant substrates.…
In this paper, novel approaches for the synthesis of Type-II core/shell quantum dots (ZnTe/ZnSe QDs) and Mn <sup>2+</sup> -doped Type-II core/shell quantum dots (Mn : ZnTe/ZnSe QDs) with mercaptopropionic acid (MPA) as stabilizer were proposed.
The efficient removal of trace carcinogenic organic pollutants, such as polycyclic aromatic hydrocarbons (PAHs) and ionic dyes, from water is an important technical challenge. We report a highly effective recyclable multifunctional azobenzene (AZ)-based silica-supported polymeric adsorbent which can simultaneously rem…
An analytical study is presented of the double resonant Raman scattering process in graphene, responsible for the D and ${\mathrm{D}}^{\ensuremath{'}}$ features in the Raman spectra. This work yields analytical expressions for the D and ${\mathrm{D}}^{\ensuremath{'}}$ integrated Raman intensities that explicitly show…
Due to increasing application, release of nanoparticles (NPs) and nanomaterials into the environment becomes likely. Knowledge about NP uptake in organisms is crucial for risk assessment including estimations on the behavior of NPs based on their physicochemical properties. In the present study, the authors have appli…
The noncovalent binding of the gold hemispheres of polystyrene/gold colloidal Janus spheres in aqueous solution was found to depend more significantly on the deposition thickness of the particle's gold layer than the chemistry of a covalently affixed self-assembled monolayer on the gold. By means of two-channel confoc…
Monodisperse and water-soluble Cys-Au dots with near-infrared emission successfully prepared by a one-pot synthesis approach, and the as-prepared Au dots could be used for long-term tumor cell imaging and highly selective detecting Pb <sup>2+</sup> .
Investigation of crystal structure, microstructure, local ferroelectric, and magnetic properties of the aliovalent-doped Bi0.95Ca0.05Fe1−yByO3 (B = Ti and Mn; y = 0, 0.05, 0.1) perovskites has been carried out at room temperature to illustrate the role of anion vacancies in the suppression of cycloidal antiferromagnet…
Eu 2+ doped Sr 2 Al 2 SiO 7 cyan-green emitting phosphors have been synthesized with solid-state reaction method. With Rietveld refinement technique, Sr 2 Al 2 SiO 7 equivalent sites and atomic positions were acquired. The Sr 2 Al 2 SiO 7 :Eu 2+ photoluminescence at room and high temperature were investigated. This ph…
Surface-enhanced Raman scattering (SERS) spectroscopy was employed in the present work to elucidate the adsorption of two diisocyanide molecules: 1,4-phenylenediisocyanide (PDI) and 1,4″-terphenylenediisocyanide (TPDI) on nanogaps of Ag and Au nanoparticles (NPs). The main goal of this work was the study of the adsorp…
Biomineralization is the intricate, biomedically highly relevant process by which living organisms deposit minerals on biological matrices to stiffen tissues and build skeletal structures and shells. Rapaport and coworkers ( J. Am. Chem. Soc. 2000 , 122 , 12523 ; Adv. Funct. Mater. 2008 , 18 , 2889 ; Acta Biomater. 20…
The manipulation of the heat flow in a ceramic matrix composite is of great importance in industrial and academic fields.
The X-ray powder diffraction pattern shows that at room temperature, [N(CH3)3H]2ZnCl4 is crystallized in the orthorhombic system with Pnma space group. The phase transitions at T1 = 255 K, T2 = 282 K, T3 = 302 K, T4 = 320 K, and T5 = 346 K have been confirmed by the differential scanning calorimetry. The electrical te…
The wetting configuration of a liquid droplet on a rough or physically patterned surface is typically characterized by either the Cassie wetting mode, in which the droplet resides on top of the roughness, or the Wenzel mode, in which the droplet penetrates into the roughness. For a fixed surface topology and droplet s…
The epitaxial relationship in the thermal phase transition between double gyroid (DG) and hexagonally packed cylinder (HEX) phases in polystyrene- block -polyisoprene thin films on Si wafer was investigated using transmission electron microtomography and grazing incidence small-angle X-ray scattering. Two different ty…
Oxidation–reduction potential (ORP) was applied to monitor and control the oxidation reaction of peroxide hydrogen in the degumming process of ramie fibers. The effects of original pH, hydrogen peroxide dosage, oxidation temperature, and reaction time on ORP variations and fiber degumming efficiency were fully investi…
The complex [Ph4P]2[Cu(bdt)2] (1(red)) was synthesized by the reaction of [Ph4P]2[S2MoS2CuCl] with H2bdt (bdt = benzene-1,2-dithiolate) in basic medium. 1(red) is highly susceptible toward dioxygen, affording the one electron oxidized diamagnetic compound [Ph4P][Cu(bdt)2] (1(ox)). The interconversion between these two…
Lignin was used as a template for the first time to in situ synthesize lignin-based silver nanoparticles composites using sodium borohydride or ascorbic acid as a reducing agent. The lignin-based silver nanoparticles composites were characterized by means of X-ray diffraction, scanning electron microscopy, transmissio…
Corona phase molecular recognition (CoPhMoRe) has been recently introduced as a means of generating synthetic molecular recognition sites on nanoparticle surfaces. A synthetic heteropolymer is adsorbed and confined to the surface of a nanoparticle, forming a corona phase capable of highly selective molecular recogniti…
