To better understand the effect of functional molecule types to the surface properties of ZnO nanorods, three organic molecules – ethylenediamine, sodium citrate and butanethiol were used for the surface modification of ZnO nanorods.
pH responsive poly(N,N'-methylenebisacrylamide-co-4-vinylpyridine) (P(MBA-4VP)) one dimensional (1D) nanostructures have been prepared by metallogel template copolymerization, which was carried out in an Ag(i)-coordinated organogel with benzoyl peroxide (BPO) as the initiator. The product has been characterized using…
Phthalonitrile and benzaldehyde bearing α-nitronyl and α-imino nitroxide free radicals have been synthesized as precursors of nitroxide substituted phthalocyanine and porphyrin macrocycle.
In this work we present the synthesis, time-resolved spectroscopic characterization and computational analysis of a bichromophore composed of two very well-known naturally occurring dyes: 7-hydroxycoumarin (umbelliferone) and 1,2-dihydroxyanthraquinone (alizarin). The umbelliferone donor (Dn) and alizarin acceptor (Ac…
2D poly(2,5-dimethoxyaniline) nanosheets were designed via a green interfacial strategy, and demonstrated large specific capacitance and striking stability at high rates as a pseudo-capacitive electrode.
Radionuclides naturally occurring in building materials may significantly contribute to the annual doses to the public. For instance, familiar building materials such as the concrete and gypsum board have been reported to produce a dose of about 0.04 mSv per year for a typical person (NCRP 1987c). External as well as…
The structural stability, elastic modulus, hardness and electronic structure of RuB 2−x (0 ≤ x ≤ 2) borides are systematically investigated using a first-principles approach.
Molten silicate glasses are complex media in which ionic species can be easily dissolved. That typically concerns the metallic cations or oxoanions. The as-described liquids have therefore the properties of electroactive solutions in which the ions displacements allow the electrical conduction. As a consequence, the u…
Ultra-small hydrosol LBH-AuNPs were synthesized, and their application in the FRET based estimation of collagen investigated using bi-ligand functionalised LBH-AuNPs.
We investigated the role of pH in the vapor hydration at 175 oC of the French SON68 glass using controlled atmospheres. Hence, experiments were conducted under ammonia and hydrogen sulfide to respectively simulate high and low pH conditions. Results were compared with those obtained under air. Glass hydration and surf…
A novel starphene containing sulfur exhibits an excellent FET performance with a mobility of 0.56 cm 2 V −1 s −1 based on the single-crystal nanowires.
Polyelectrolyte nanocapsules, consisting of poly(allylamine hydrochloride) (PAH) and a nucleic acid, i.e. either DNA or siRNA, were prepared with calcium phosphate nanoparticles as template. This inorganic core was removed by a combination of acid treatment and dialysis, leading to capsules with a diameter of about 14…
TiO 2 @CdSe/CdS hollow nanospheres solar paint were fabricated and directly applied in quantum dot-sensitized solar cell. The reliable conversion efficiency of 0.79 was achieved with a current density of 6.6 mA cm −2 .
Geomaterials (soils and rocks) exhibit peculiar physical, chemical, mineralogical and biological properties, which influence their interaction with the contaminant(s) to a great extent. This interaction can be quantified by employing a parameter ‘Distribution coefficient’, kd, which plays an important role for determi…
Water is used globally for cooling purposes in industry.During its re-use, scaling and deposition can develop due to the high content of dissolved species.Among the toughest to combat is silica scale, or amorphous silicon dioxide.In this paper, we present how certain chemical interventions in the water chemistry can b…
Novel water-soluble metallophthalocyanines (M: Co, Ni, Cu, Zn) containing azo dye were characterized. The structures were confirmed by IR, UV/vis, ^1H NMR, ^{13}C NMR, mass spectroscopy, and elemental analysis. Photochemical properties and aggregation behavior of zinc phthalocyanines were investigated. Singlet oxygen…
This article tries to uncover the physical reason of Cu precipitation from an Fe matrix at the electronic level. The general rule is obtained that the more bonds among Cu atoms, the more stable the system is. It was shown that Cu would precipitate from the matrix with Fe spin-polarization but not without spin-polariza…
With the assist of dual‐molecules, 2‐(N‐morpholino)ethanesulfonic acid (MES) and sodium citrate, gold nanoparticles (GNPs) with different shapes can be generated in the H 2 O 2 ‐mediated reduction of chloroauric acid. This one‐pot reaction can be employed to sensitively detect H 2 O 2 , probe substrates or enzymes in…
For reversible hydrogen storage properties of 17MgH2 + 12Al ↔ Mg17Al12 + 17H2, MgH2/Al nanocomposites (I)–(IV) synthesized by ball milling of MgH2 and Al (or AlH3) were studied in connection with milling conditions. The milling processes consisting of two steps were effective to improve the hydrogen storage behavior;…
The influence of cold rolling on diffusion bondability has been systematically investigated using SUS316L stainless steel sheets with different reduction ratios (0, 35, 50 and 70%) as specimens. According to the results of tensile testing of diffusion bonds, highly rolled sheets exhibit enhanced diffusion bondability.…
