Hafnium‐containing compounds are of great importance to the semiconductor industry as a high‐κ gate dielectric to replace silicon oxynitrides. Here, the crystallization processes and chemistry of bulk hafnia powders are investigated, which will aid in interpretation of reactions and crystalli...
Hafnium oxide and silicate materials are now incorporated into working CMOS devices; however, the crystallization mechanism is still poorly understood. In particular, addition of SiO2 to HfO2 has been shown to increase the crystallization temperature of HfO2, hence, allowing it to remain amorpho...
We perform a single-shot IR nanosecond laser processing of commercial silicon wafers in ambient air and under a 2 mm thick carbon disulfide liquid layer. We characterize the surface spots modified in the liquid ambient and the spots ablated under the same conditions in air in terms of its surfac...
A synthesis of high-purity silicon disulfide SiS 2 is described, and the F.t.-Raman spectrum of the solid is reported for the first time. The standard massic energy of reaction of SiS 2 (cr) with fluorine was measured in a bomb calorimeter. The combustion reaction was shown to pr...
It was demonstrated experimentally that the spatial separation of two processes of chemical vapor deposition, one of which provides synthesis of filler (MoS2) nanoparticles and the other yields the matrix (SiO2) of the nanocomposite coating, performed ina common reactor, enables an independent c...
The synthesis and characterization of the first bis‐N‐heterocyclic carbene stabilized monomeric silicon disulfide (bis‐NHC)SiS22 (bis‐NHC=H2C[{NC(H)C(H)N(Dipp)}C:]2, Dipp=2,6‐iPr2C6H3) is reported. Compound 2 is prepared in 89 % yield from the reaction of the zero‐valent silicon complex (′...
Self-consistent density functional theory calculations of band spectra, densities of states as well as the spatial distribution of valence electron charge density were carried out for the low-pressure α-phase and the high-pressure β-phase of SiS2. Group-theoretical analysis performed for both ...
. The present paper provides a comparative analysis between nano and hybrid nanofluid axisymmetric flow towards a radially stretching porous surface along with heat transfer mechanism in the presence of magnetic force and internal heat source/sink. The effect of various shapes of nanoparticles i...
Two-dimensional transition-metal dichalcogenides (TMDCs) are very promising for photovoltaic (PV) applications due to their excellent light absorption properties and appropriate bandgap energy, Although multifunctional applications of TMDCs in photovoltaic devices have been achieved, the photovo...
The natural product triostin A is known as an antibiotic based on specific DNA recognition. Structurally, a bicyclic depsipeptide backbone provides a well-defined scaffold preorganizing the recognition motifs for bisintercalation. Replacing the intercalating quinoxaline moieties of triostin A by...
Six or seven triostin-binding sites have been identified in a 160-base-pair DNA restriction fragment containing the tyr T promoter sequence. Each is centred round a CpG step, and the minimum binding site-size appears to be six base pairs. The sites are practically the same as those reported for ...
Interferometric infrared and Raman spectra of thallium nitroprusside (Tl 2 [Fe(CN) 5 NO]), with normal isotopic composition or substituted with 1 3 C (98.5%), were obtained from 4000 to 50 cm - 1 at room and low temperature (boiling liquid air). Infrared m...
The Fourier transform infrared and NIR Raman spectra between 4000 and 50 cm - 1 of sodium nitroprusside dihydrate, Na 2 [Fe(CN) 5 NO] 2H 2 O, normal and enriched with 5 4 Fe, 1 3 C and 1 5 N(O), have been obtained. Resul...
A new force field was calculated for the nitroprusside anion, [Fe(CN) 5 NO] 2− , using density functional theory (DFT). This force field was converted to symmetry coordinates and scaled to reproduce the experimental wavenumbers of the normal vibrations. The obtained set of force ...
The bismuth‐coated electrode is known to be prone to errors caused by copper(II). This study investigates copper(II) interference at bismuth film electrode for the detection of lead(II) and cadmium(II). It was conducted using glassy carbon electrode, while the bismuth film was plated in situ si...
Interaction of ribose nucleotides with cobalt- and cadmium ferrocyanides was found maximum at neutral pH. Adsorption trend followed Langmuir isotherms. The Langmuir constants, X m and K L were calculated. Purine nucleotides adsorbed more than pyrimidine nucleotides on both the me...
Adsorption of glycine and β-alanine on nickel, cobalt and cadmium ferrocyanides has been studied at neutral pH (7.0±0.01) and room temperature (30±1°C). The progress of adsorption was followed spectrophotometrically by measuring the absorbance of amino acids solution at their corresponding λ...
Nitric oxide (NO) is a gaseous signaling molecule in plants that plays a key role in mediating a wide range of physiological processes and responses to biotic and abiotic stresses. The present study was conducted to investigate the effects of the exogenous application of sodium nitroprusside (SN...
The development of graphene/polyaniline/polystyrene (G/PANI/PS) nanoporous fiber modified screen-printed carbon electrode (SPCE) using electrospinning fabrication for simultaneous determination of lead (Pb2+) and cadmium (Cd2+) was achieved. Initially, the important factors controlling the elect...
Nitrogenous amorphous carbon (a‐CNx) thin films were deposited by radio‐frequency cathodic magnetron sputtering (13.56 MHz) on polished and etched titanium disks. While these films are cheaper to prepare than commonly reported carbon‐based electrodes, the usable electrochemical window in aque...
