A chiral, tetradentate polyether ligand with a trans-1,2-cyclohexanediyl backbone, bis(methoxyethoxy)-trans-1,2-cyclohexane (5), was synthesized as both a racemate and the (S,S) enantiomer. 5 was found to form stable adducts with alkaline earth metal amides [M{N(SiMe(3))(2)}(2)(thf)(x)] (M = Mg (x = 0), Ca (x = 2) and…
Surface imprinting and adoption of a nano-sized physical form are two effective approaches to overcome the template transfer difficulty within molecularly imprinted polymers (MIPs). This work is an attempt to conquer the problem of template transfer difficulty within MIPs by using a nano-reactor as a substrate for the…
We have focused on the generation of various nanostructures of poly(ε-caprolactone) (PCL) using surface modified layered silicate. The improved and diverse mechanical, thermal and surface properties have been explored depending upon the nanostructure of the nanohybrids. The incorporation of drug into those nanohybrids…
We describe a simple and green method for preparing silver nanoparticles with an average diameter in the range from 4.0 nm to 5.0 nm and with the standard deviation as low as 0.3 nm (polydispersity: 5.5%). The pre-synthesized silver oleate precursor in oleic acid was thermally reduced to obtain the monodisperse silver…
The chemical inertness of graphite and, in the case of tubes, of rolled up few layer graphene sheets, requires some degree of “defect engineering” for the fabrication of carbon based heterostructured materials. It is shown that atomic layer deposition provides a means to specifically label anchoring sites and can be u…
Uniform and well-crystallized NaLa(MoO4)2 microspheres were prepared by a facile one-step hydrothermal synthesis without involving any surfactants or templates. The as-obtained products were systematically characterized by powder X-ray diffraction (XRD), field emission-scanning electron microscopy (FE-SEM), transmissi…
Thermally irreversible photochromic 1-tert-butyl-substituted 2,3-bisthiazolylindenol has been synthesized. It showed perfect diastereoselectivity and high ring-closing quantum yield with high conversion ratio to the closed form. The collaborative interaction of two intramolecular hydrogen bonds and the steric restrict…
Porous NiO nanospheres are synthesised with the assistance of an eggshell membrane. The resulting NiO nanospheres are composed of well distributed nanoparticles of 5–10 nm in diameter with high surface areas and good electrolyte wetting, which result in a good capacitive performance of 550 F g−1 at a current density o…
A facile dip-coating approach was developed to fabricate visible/near-IR antireflective and superhydrophobic coatings on glass substrates from hydrophobic hexamethyldisilazane (HMDS)-modified hollow silica nanoparticles (HMDS–HSNs) and poly(methyl methacrylate) (PMMA). While the coated glass substrates showed greatly…
We report nickel oxide (NiO) fine nanoparticles with an average diameter of 5.3 ± 1.3 nm as an electrode material for supercapacitor reactions. The superior pseudocapacitive behavior of NiO nanoparticles was demonstrated in three-electrode half-cells and two-electrode button cells, with a maximum specific capacitance…
A comparative study was performed on the sorption capacity of the phenoxy acid herbicide (4-chloro-2-methylphenoxyacetic acid), also known as MCPA, on a single-walled carbon nanotube (SWCNT), three multi-walled carbon nanotubes with average outer diameters of 15, 30 and 50 nm (MWCNT15, MWCNT30 and MWCNT50), and nanosc…
Liquid marbles are liquid droplets covered with hydrophobic particles. This particular layer physically isolates them from the substrate on which they are deposited. In this study, we investigate the properties of such liquid marbles when impacting onto a solid substrate. The different behaviors during impact (non-bou…
Silica fiber with highly ordered mesoporous structure and continuously long fibrous property was synthesized on a large-scale for the first time. It can be applied to the rapid (less than 3 min) and effective enrichment of endogenous peptides with a novel lab-in-syringe approach.
Sulfated polyvinyl alcohol functionalized carbon black, stable under high temperature and high salinity conditions, efficiently carries a hydrophobic compound through a variety of oil-field rock types and releases the compound when the rock contains hydrocarbons.
The homogeneous LaF3:Yb3+/Tm3+ nanocrystals (NCs) with an average diameter of 5 nm and different doping concentrations (Yb3+: 2–20%, Tm3+: 0.2–1.5%) were synthesized by a simple solvothermal approach. Their emission spectra, luminescent dynamics, and power-dependence of up-conversion (UC) photoluminescence were invest…
Using dissipative particle dynamics simulations, we have studied the effect of Janus nanospheres on the phase separation dynamics of polymer blends. We find that Janus nanospheres significantly impede domain growth and at a later stage the average domain size approaches saturation and the growth exponent n decays to n…
An ionic solid catalyst by pairing Keggin polyoxometalate-anions with Pd(II)-coordinated nitrile-tethered ionic liquid cations was synthesized, characterized, and tested for aerobic oxidation of benzene to biphenyl. A unique heterogeneous intramolecular electron transfer mechanism is proposed to understand its high ac…
Properties of free-standing nanomembranes prepared by blending poly(3-thiophene methyl acetate) and poly(tetramethylene succinate), a soluble polythiophene derivative and a biodegradable polyester, respectively, have been examined. The outstanding flexibility and robustness of the nanomembranes floating in ethanol hav…
The thin nanofibrous layer has different properties in the field of sound absorption in comparison with porous fibrous material which works on a principle of friction of air particles in contact with walls of pores. In case of the thin nanofibrous layer, which represents a sound absorber here, the energy of sonic wave…
This study employed various polyol solvents to synthesize zinc oxide polycrystalline nanostructures in the form of fibers (1D), rhombic flakes (2D), and spheres (3D). The synthetic process primarily involved the use of zinc acetate dihydrate in polyol solutions, which were used to derive precursors of zinc alkoxides.…
