In the present part of study, the effect of thiosulfate ion on pitting corrosion of AISI 316 stainless steel in 0.1 M NaCl solution was investigated. In order to elucidate the effect of thiosulfate on pitting corrosion, the metastable pitting has been studied in more details. The results showed that the thiosulfate ad…
We investigate the self-assembly of colloidal Janus particles under shear flow by employing hybrid molecular dynamics simulations that explicitly take into account hydrodynamic interactions. Under quiescent conditions, the amphiphilic colloids form spherical micellar aggregates of different sizes, where the solvophobi…
Three-dimensional porous graphene–carbon nanotube hybrid papers were obtained as a conductive, flexible and free-standing nano-scaffold for PANI immobilization.
Recent progress in modelling the solvent vapor annealing of thin film block copolymers is examined in the context of a self-consistent field theory framework. Key control variables in determining the final microdomain morphologies include swelling ratio or swollen film solvent volume fraction, swollen film thickness,…
A potentially useful strategy for tuning the inversion parameter in spinel nanoferrites – and thus their magnetic characteristics – is demonstrated.
In order to utilize the high strength and stiffness of cellulose nanofibrils in a macroscopic material or composite, the structure of the elongated fibrils in the material must be controlled.
Nitrogen-doped graphene nanoribbons (N-GNRs) were prepared by thermal treatment of the as-zipped graphene oxide nanoribbons in NH3 gas. X-ray photoelectron spectroscopy (XPS) measurements revealed a high nitrogen content up to 6.5 atom% for the as-prepared N-GNRs. This, together with the high Brunauer-Emmett-Teller (B…
Herein, we demonstrated facile fabrication of NiCo 2 O 4 nanoparticles on a CNT film by a chemical deposition method, followed by thermal annealing treatment processing.
Naphthyridinic fluorescent receptors ( 1 and 2 ) were utilized for the selective detection of picric acid (PA) in aqueous media and are able to detect ∼1 ppm of PA via a fluorescent ‘turn off’ mode.
The metallization of plastics materials, dealing with a lot of industrial applications in the field of automotive, electronic, etc. …, is generally performed by a chemical and/or electrochemical process not so ecofriendly.
Grass-like CuCo 2 O 4 nanowire arrays (CCO NWAs) supported on nickel foam, were prepared through a facile hydrothermal process. The stability of the morphology makes the CCO NWAs promising for electrochemical applications.
It was shown that the solution mixing method is able to disperse natural and organically modified clays in novolac resin efficiently. Development of a strong interphase region around the silicate layers was also explored.
Sensitizers with high triplet quantum yields are useful for generating photovoltaics, photocatalysts and photodynamic therapy agents with increased efficiency. In this study, the heavy atom effect was used to optimize the triplet and singlet oxygen quantum yields of 5,10,15,20-tetrakis(4-carbomethoxyphenyl)porphyrin (…
An isopolyoxomolybdate-based POM is coordinated to trivalent cerium ions to afford a hybrid complex namely, [Ce(dmso)8][Ce(η2-NO3)2(dmso)4(α-Mo8O26)0.5][Mo6O19]. The original electrostatic environment created around the Ce(III) by its coordination to the isopolyoxomolybdate core induces complex single-molecule magnet…
A study on the corrosion and scaling inhibition efficiencies of some amine derivatives for carbon steel.
Hydration reaction of CO2 is one of the rate limiting steps for CO2 absorption (in aqueous solutions) and aqueous CO2 mineralization. The catalytic activity of nickel nanoparticles (NiNPs) for CO2 hydration is studied at different temperatures, pH, and low CO2 partial pressures to mimic the true flue gas conditions. R…
Herein, we have designed composite SERS-active micro-satellites, which exhibit a dual role: (i) effective probes for determining cellular composition and (ii) optically movable and easily detectable markers. The satellites were synthesized by the layer-by-layer assisted decoration of silica microparticles with metal (…
This study demonstrates the beneficial role of di-tryptophan containing short peptide amphiphiles (sPA), for the synthesis and stabilization of AgNPs in the presence of sunlight followed by garlanding of AgNPs along the fibrous network of sPA. Such hybrid structures were precisely and selectively moulded into a nanowr…
An environmental-friendly glyoxal-urea (GU) resin is synthesized from urea and glyoxal, and combined with nano-SiO 2 to treat Poplar wood and endow it superior mechanical and thermal properties.
The paper presents the development of experimental investigations and recent results of the impact on tungsten at high level of radiation damage under steady-state deuterium plasma. Tungsten is considered as a plasma facing material for a fusion reactor. The effect of fusion neutron impact is simulated by surrogate ir…
