Ключевые слова (''Своб.индексиров.''): nanodiamond--nanoparticle--metal-containing plasma
Аннотация: This paper describes coating of diamond powder with metal by plasma. Arc plasma was generated in double jet high-frequency argon-operated plasmatron with atomized metal inserts. The diamond powder was added to the plasma in a flow of helium. Copper and nickel coated particles of detonation and industrial diamonds were studied by XRD, XPS, SEM methods and electron magnetic resonance. Results of these studies are presented.

Ключевые слова (''Своб.индексиров.''): chemical change--diamond grains--experimental spectra--experimental studies--ir spectrum--mechanical force--detonation--diamonds--x ray diffraction--agglomeration
Аннотация: A diamond-containing material (DCM) produced by detonation was mechanically milled using KM-1 and AGO-2S mills. Experimental spectra for infrared (IR) absorption, Raman scattering and X-ray diffraction patterns (XRD) were obtained for the treated DCM samples. We compared the Raman and IR spectra for the KM-1 milled samples and concluded that the surface of the DCM particles was not uniform. The mechanical force that resulted from milling with the AGO-2S destroyed the non-diamond part of the particles and initiated irreversible physical and chemical changes in them. The destruction of the diamond grains was the consequence of these irreversible changes. It follows from the experiments that the dipole momentum of the DCM particle was caused by the presence of polar fragments of molecules. The constant dipole momentum of the particles facilitated the aggregation. Based on this, we proposed a model of a structurally inhomogeneous DCM particle. В© 2012 EDP Sciences.

Заглавие : Electrical and magnetic properties of nanodiamond and pyrocarbon composites
Место публикации : Russ. J. Gen. Chem. - 2013. - Vol. 83, Is. 11. - P.2173-2181. - ISSN 1070-3632, DOI 10.1134/S1070363213110376
Аннотация: The electrical and magnetic properties of the nanodiamond composites comprising nanodiamond, pyrolytic carbon, and nanosized pores were studied. The composites are p-type semiconductors and their resistance decreases by 12 orders of magnitude as the pyrocarbon-to-diamond ratio γ increases from 0 to 80 wt %. Evidence for paramagnetic properties of the nanodiamond composites was obtained. The observed properties are explained by increased concentration of surface Tamm states. The paramagnetic properties are explained in terms of the electron spins localized on the nanodiamond surface in the composite.

Ключевые слова (''Своб.индексиров.''): ferromagnetic powder--local magnetic anisotropy--nanocorundum--nanodiamond
Аннотация: In this paper we have proposed a modified expression for the fitting M(T) data in Co-P powders with nanocorundum and nanodiamond precipitates. The expression for M(T) takes into account the effects from both thermal magnetic excitations – Bloch’s T 3/2 law and temperature dependence of the magnetic anisotropy. The fitting parameters are spontaneous magnetization at absolute zero temperature, Bloch constant and order of magnetic anisotropy constant. The obtained Bloch constant is in good agreement with literature data. The order of magnetic anisotropy constant is found to be about 3 that is surprising result and supposedly comes from multiphase nature of the investigated Co-P powder.

Заглавие : Surface modification of detonation nanodiamonds with platinum and palladium nanoparticles

Ключевые слова (''Своб.индексиров.''): detonation-synthesized nanodiamond supports--platinum and palladium nanoparticles--combustion--chemical modific--dnd additional purification
Аннотация: Acetylacetonates of platinum group metals (M(acac)n, acac= CH3COCHCOCH3,n - oxidation state of metal) are the most suitable precursors for use in highly effective MOCVD (metal-organic chemical vapor deposition) processes because of their thermal properties, low price of initial ligand and accessible synthesis methods. In this study we have developed a simple, scalable inexpensive, MOCVD-like approach to the deposition of Pt and Pd nanoparticle dispersions on powder detonation nanodiamonds (DND) using combustion in air of powder mixtures of DND with Pt and Pd acetylacetonates. This one-step process requires no specialized apparatus, and is conducted at mild temperatures (180°C – 250°C). The substrate surface of DND initiates chemical thermal destruction of precursor and deposition of nanoparticle networks composed of constituent particles. DND-supported Pd and Pt nanoparticles with their loading being from 10 and 5wt. % were obtained the average of particle size 20-25 nm and 7-10nm decreases with decreasing the metal loading. For additional purification and disaggregation of the commercial detonation-synthesized nanodiamond (DNDcomm) the method of annealing of the powder mixtures DNDcomm with Na(acac) have been used. The purified diamond nanoparticulates (DND), as well as DNDcomm, Pt/DND and Pd/DND, were subjected to physicochemical characterizations, such as X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy dispersive X-ray (EDX) analysis.

Аннотация: Experimental data have been presented on the influence of silver on the viscosity and thermal conductivity of a dispersion of diamond nanoparticles. A stable dispersion (5 wt %) of detonation nanodiamond particles has been used in the experiments. Silver ions have been introduced electrolytically into the dispersion of diamond nanoparticles. Silver concentration was not higher than 0.05 wt %. It has been shown that the introduction of silver ions significantly affects the thermal conductivity and viscosity of the dispersion.

Заглавие : The effect of copper and iron adsorption on the catalytic performance of alumina nanofiber / nanodiamond composite in sensing applications

Аннотация: Phenolic compounds are common environmental pollutants, which are used in many industries and contaminate water environment due to industrial wastewater discharge. Presently, there is an increasing demand for the development and improvement of inexpensive, easy-to-use analytical tools for in-situ detection of phenolic compounds. In this work, we investigate the effect of adsorption of Cu2+ and Fe2+ ions on the catalytic activity of a composite material based on alumina nanofibers (ANF) and detonation nanodiamonds (DND) in the co-oxidation of phenols with 4-aminoantipyrine in the presence of hydrogen peroxide. We have found more than two-fold increase of the catalytic activity for ANF + DND + Cu composite, while the activity of ANF + DND + Fe composite is found to decrease by several times in comparison with the original ANF + DND material. The results of FTIR analysis indicate that the adsorption of iron ions occurs with the formation of hydroxide surface groups and hydrogen bonds, which apparently block their catalytic activity in the Fenton redox cycle. The higher catalytic performance of AND + DND composite functionalized with copper ions makes it possible to detect two times lower concentrations of analytes (phenol and 4-chlorophenol) in comparison with the original composite. It is shown that the AND + DND + Cu composite provides a linear yield of the co-oxidation reaction product in a wide range of analyte concentrations (0.25–100 μM for phenol and 0.5–25 μM for 4-chlorophenol). Model experiments demonstrate the applicability of copper-functionalized composite as a reusable sensor for the determination of phenol in aqueous samples.
