We successfully synthesized large-scale and highly pure ultrathin SnO 2 nanosheets (NSs), with a minimum thickness in the regime of ca. 2.1 nm as determined by HRTEM and in good agreement with XRD refinements and AFM height profiles. Through TEM and HRTEM observations on time-dependent samples, we found that the as-pr…

The effects of structural properties on the d.c. and a.c. electrical properties of different weight gain reaction bonded silicon nitride (RBSN) have been studied in this work. The degree of nitridation is assessed by the 'weight gain' of the ceramic, the percentage by which the weight is increased in the nitriding rea…
Owing to a technical mistake, we erroneously used the wrong computer file for plotting the magnetic structure of the solution that we found for the irreducible representation (irrep) τ 2 , which was shown in figure 4(b) in the original article. See the PDF for a full correction.
We have investigated the effect of local magnetic moment on the electrical and magneto-transport properties of thin films of the degenerate semiconductor Ti(1-x)Fe(x)O(2-d) (x = 0,0.04). The electrical measurements of these films reveal high temperature metallic behavior and resistivity minima. The behavior below the…
Silver coatings at the nanoscale became of high interest for the integration of electronic functionalities on all kinds of objects for daily use. In these thin coatings, corrosion is a big problem as it destroys these thin layers and leads to a loss of conductivity due to missing bulk material. For protection of thin…
Abstract Natural montmorillonite (MMT) clay nanomaterials were successfully dispersed in poly(ethylene terephthalate) (PET) through two new and enhanced in situ polymerization methods. In the case of PET/MMT nanocomposites prepared through the esterification (ES) reaction clay‐addition method, unmodified MMT clays wer…
In metallic systems, strong screening of the Coulomb interaction between an electron and a hole by free electrons largely prevents the formation of an exciton. In one-dimensional metallic systems, however, the screening effect is significantly reduced. Recent theoretical and experimental studies suggest that an excito…
Incubation of CaCO(3) microparticles in chitosan (CS) solution at pH 5.2 and following with ethylenediaminetetraacetic acid disodium salt (EDTA) treatment resulted in CS single-component microcapsules with an ultra-thick wall structure. Repeating the incubation caused stepwise increase of wall thickness and finally re…
Let S S be the union of finitely many disjoint intervals on R \mathbb {R} . Suppose that there are two real numbers α , β \alpha , \beta such that the length of each interval belongs to Z α + Z β \mathbb {Z} \alpha + \mathbb {Z}\beta . We use quasicrystals to construct a discrete set Λ ⊂ R \Lambda \subset \mathbb {R}…
In Chapter 7, the electric properties of tellurite glasses are explained, and the dielectric constant (ɛ) and loss factor data are summarized for both oxide and nonoxide-tellurite glasses. These values vary inversely with frequency (f) and directly with temperature (T). The rates of change of ɛ with f and T, complex d…
A series of phosphate glasses of composition 45P2O5–(40 − x)CaO–15Na2O–xAg2O (x = 0, 3, 6, 8, 10 and 12 mol%) with different Ag2O contents were prepared using the melt-quenching technique. The incorporated Ag2O highly influenced the increase of its transition tendency towards crystallisation and, on contrary, reduced…
The physical and chemical characteristics of kaolinite (kaolin) may be variable, and minor amounts of other clay minerals, nonclay minerals, and other impurities may affect the properties of kaolinites. Thus specific technical properties of pharmaceutical grade kaolinites become very important because these clays are…
Abstract Attempts have been made for the first time to employ graphitized nanodiamond with the cage‐like structure to prepare thermoplastic elastomer (TPE) nanocomposites based on polypropylene (PP) and ethylene‐propylene‐diene rubber (EPDM), with improved tribo‐dynamic properties. Samples were prepared via melt mixin…
The long-range magnetic ordering of PrMn(2)O(5) has been studied on polycrystalline samples from neutron diffraction and specific heat measurements. The onset of antiferromagnetic ordering is observed at T(N) ≈ 25 K. In the temperature interval 18 K < T < 25 K the magnetic structure is defined by the propagation vecto…
The aims of this work were to investigate the effect and mechanism of improving industrial pickling by synergistic corrosion inhibition, as well as to propose a strategy for cleaner pickling. Using the methods of weight-loss, electrochemical polarization, and scanning electron microscopy (SEM) observation, it was reve…
Thioglycolic acid (TGA)-capped CdTe nanoparticles (NPs) were synthesized in aqueous medium, and their application as fluorescence probes in the detection of adenine and guanine was studied. The TGA-capped CdTe NPs were characterized by transmission electron microscopy, X–ray diffraction spectrometry, spectrofluorometr…
The hydridoirida-β-diketone [IrHCl{(PPh(2)(o-C(6)H(4)CO))(2)H}] (1) reacts with benzylamine (C(6)H(5)CH(2)NH(2)) to give the hydridoirida-β-ketoimine [IrHCl{(PPh(2)(o-C(6)H(4)CO))(PPh(2)(o-C(6)H(4)CNCH(2)C(6)H(5)))H}] (2), stabilized by an intramolecular hydrogen bond. 2 reacts with water to undergo hydrolysis and ami…
Hot water extractives, solvent extractives and both hot water and solvent extractives were eliminated from different wood species via Soxhlet extraction. Different wood–linear low density polyethylene (LLDPE) composites were prepared using 10% wood and 7% poly(ethylene-co-vinyl alcohol) as a compatibilizer. A comparis…
The energetics of point defects in Ga stabilised δ-Pu are investigated through calculations of formation energies, migration pathways and through on-the-fly kinetic Monte Carlo (OTF-KMC) calculations. Using the Modified Embedded Atom Method as the interatomic potential, defect formation energies are found to depend gr…
