The paper presents the research results of high performance modified concretes with complex hydrophobization modifiers and hydrophobic tragers. It is known that the concrete durability largely depends on its filtering characteristics, which can be lowered by adding hydrophobization additives to the concrete compositio…
The influence of neodymium (Nd) contents on the structural, electrical and dielectric properties of Nickel cobalt ferrites was studied in the ferrite series NixCO1-xNdyFe2-yO4 (x= 0.00, 0.20, 0.40, 0.60, 0.80, 1.0 and y = 0.00, 0.02, 0.04, 0.06, 0.08, 0.1). This series was prepared by sol-gel method. XRD analysis reve…
Fe 3 O 4 nanosheet arrays can grow on graphene by a mussel-inspired polydopamine adhesive towards remarkable enhancement in electromagnetic absorptions.
The starting complexes [PtCl(C^N)(dmso)], in which C^N is either ppy = 2-phenylpyridinate, , or bhq = 7,8-benzo[h]quinolinate, , were prepared by a known method using the reaction of [PtCl2(dmso)2] with ppyH or bhqH, respectively, in toluene under reflux conditions. The reaction of [PtCl(C^N)(dmso)], or , with 1 equiv…
The landmark theoretical properties of low dimensional materials have driven more than a decade of research on carbon nanotubes (CNTs) and related nanostructures. While studies on isolated CNTs report behavior that aligns closely with theoretical predictions, studies on cm-scale aligned CNT arrays (>10(10) CNTs) often…
, which is much lower than the body burden and proves its good biocompatibility. A new biocorrosion model has been established to illustrate the degradation of alloys and the formation of degradation products on the surface of the alloys. It can be concluded that the optimal concentration of Zr and Sr is less than 2 w…
In situ thermo-sensitive hydrogels have attracted increasing attention for alternative cancer therapies due to their long-term and effective drug levels at local sites. Besides synthesizing new thermo-sensitive polymers, we can also fabricate this delivery system by combining a hydrogel with a thermo-response and drug…
Two emissive Dy III complexes of crown ether macrocycles are reported. The Dy [15]-crown-5 ( 1 ) is an SMM in zero field due to a well isolated ground state, confirmed by both photoluminescence data and ab initio calculations.
New organic–inorganic hybrid compounds based on Ti-substituted polyoxometalates exhibit high photocatalytic dye (MB) degradation activities.
A biocompatible, biodegradable and redox-responsive PEGylated poly(diselenide-phosphate) nanogel was synthesized. The nanogel can potently inhibit the proliferation of tumor cells. It is a potentially efficient and self-delivery nanomedicine for cancer therapy.
Direct formation of graphene with a controlled number of graphitic layers on dielectric surfaces is achieved with an in-depth understanding of the solid-state growth mechanism.
This study demonstrates a new kind of photocatalytic system via utilization of the superior specific properties inherent in Pickering emulsions.
Agribusiness is projected to be a $ 2.9 trillion USD industry in global investment by 2030 (World Bank 2013). Nanotechnology is poised to impact dramatically on all sectors of agribusiness industry in the next 10 years. Nanotechnology could be used to enhance the possibilities of developing conventional and stranded a…
The inhibition effect of three aryl pyrazole pyridine derivatives (APPs) against the corrosion of copper in 0.5 M HCl has been investigated by electrochemical impedance, potentiodynamic polarization measurements and quantum chemical methods.
The thienoviologen series 4,4'-(2,2'-bithiophene-5,5'-diyl)bis(1-alkylpridinium)X2, with = counterion is a new class of electron acceptor materials which show very interesting electrochromic and electrofluorescence properties. Depending on the length, m, of the promesogenic alkyl chains, and on the counterion, thienov…
The structure of a glass obtained by the melt quenching of a two-dimensional (2D) coordination network was examined. X-ray analyses disclosed a 2D-to-0D structural transformation before and after glass formation. The mechanism is unique to coordination compounds, as it is characterized by labile and flexible coordinat…
A supercapacitor constructed with a partially graphitized porous carbon exhibits high energy densities of ~46 and ~43 Wh kg −1 at 50 °C and −20 °C, respectively.
Ruthenium-doped H-Montmorillonite (H-Mont) and Ti-pillared clay (Ti-PILC) were prepared then studied for oxidation of cyclohexene, with tert -butylhydroperoxide (TBHP) as the oxygen source.
The surface and near-surface chemical composition of electroceramic materials often shows significant deviations from that of the bulk. In particular, layered materials, such as cation-ordered LnBaCo2O(5+δ) perovskites (Ln = lanthanide), undergo surface and sub-surface restructuring due to the segregation of the dival…
Surfactant-modified graphene hybrids containing azobenzene groups were for the first time prepared, and the electrochemical performance was investigated. The hybrids were obtained by electrostatic interactions between cationic azobenzene-surfactants and negatively charged graphene oxide in water. The electrostatic int…
