Abstract In a previous paper, we described the adaptation of the generalized hybrid orbital (GHO) method for the use in fragment based quantum chemical approaches for large molecules like the field‐adapted adjustable density matrix assembler (FA‐ADMA). It soon became evident that the limitations of the available imple…
Carbon nanotube (CNT) has excellent lightweight properties, mechanical properties and electric conductivity, and therefore CNT is expected as the next generation conductive wires for the electric devices or as wire harnesses for the motor vehicles etc. However, the CNT is very small materials, for instance usually the…
Ti-Ag alloys with 20 and 25 mass% Ag were prepared; their surfaces were polished using silicon carbide abrasive papers. The polished alloys were immersed in a simulated body fluid (SBF), and their surfaces were observed by scanning electron microscope (SEM) to investigate the spontaneous formation of calcium phosphate…
Previous research at the Cavendish Laboratory has shown a change in failure mechanism, from that of intergranular to transgranular failure, when PBX Brazilian disc specimens are tested below the glass transition condition of their binder system. The current study builds on this earlier research, illustrating how the s…
This article presents the fabrication of shape-controllable crystalline nickel hydrazine complex structures via a simple sonochemical route. The morphologies of the nickel complex particles are self-organized into hexagonal plate-like and disk-like morphologies depending on the reaction conditions. A possible evolutio…
We report that gold nanoparticles were synthe-sized by reduction of HAuCl4 using halloysites. The synthe-sized samples were analyzed by a transmission electron microscope. The results show that the gold nanoparticles have strip-like, subcircle, and irregular shape, which are single crystals or polycrystals. Their shap…
In present paper, boronizing was applied to N80 steel tube by pack boronizing, and its effect on mechanical properties, wear and corrosion of N80 tube steel was investigated. A dual-phase boride layer composed of FeB and F2B phases was formed on the surface of the steel substrate in a hardness range of 1220–1340 HV. A…
Bismuth telluride nanowires were electrodeposited from aqueous acidic solutions containing different (20/20 and 20/10 mM) concentration ratios. The polarization plots predicted that combined solutions exhibit more noble reduction potentials than individual solutions. Optimized deposition potentials were obtained from…
In this paper, the molecular structure of a 1,8-naphthalimide fluorophore modified sextuple H-bond self-assembly homodimer, comprising two linear oligoamide molecular strands bearing arrays on one edge with complementary hydrogen bond sequences of DDADAA and AADADD, is characterized via1H NMR, ESI-MS, 13C NMR, and ele…
Two heterobimetallic precursors [Zn(TFA)3(micro-OH)Cu3(dmae)3Cl].THF (1) and [Zn(TFA)4Cu3(dmae)4] (2) [dmae=N,N-dimethylaminoethanolate and TFA=trifluoroacetate], have been synthesized and characterized by their melting points, elemental analysis, FT-IR spectroscopy, mass spectrometry, TGA and single crystal X-ray dif…
This study investigates the cold-rolling effect on the formation of Ti(Ni,Cu)2 precipitates and on the change of transformation temperatures for hot-rolled (HR)/annealed (HRA) and HR/cold-rolled/annealed (CRA) Ti50Ni40Cu10 specimens. Particle-like Ti(Ni,Cu)2 precipitates formed in CRA are more numerous and smaller tha…
Basic methods of the introduction of metal ions into the interlayer space of natural layered aluminosilicate (LAS) are considered. The physicochemical and structural properties of pillared LAS’s depend on the nature of the cation, as well as on the cation intercalation method and conditions. The catalytic properties a…
Abstract The analysis of low-energy electron diffraction (LEED) intensities from quasicrystal surfaces requires the use of periodic model structures that contain the same structure features as the quasicrystal. In this paper, we present the analysis of LEED data from 10-fold decagonal Al–Co–Ni using the W approximant…
This paper analyzes the effect of ultrasound on a batch wattle bark tannin extraction process. Extraction from wattle bark presents a unique case of a two-component system in the form of condensed tannins and non-tannins. Hence, quantitative analysis of tannin content in the extract by spectrophotometery as well as to…
Zn095Co005O films were prepared under different oxygen partial pressure P by magnetron sputtering. The effect of P on the magnetic and electrical properties was investigated. The effect of oxygen vacancy on the magnetic properties was also calculated by first-principles calculation. The experimental results indicate…
As researchers strive to understand the interplay between the complex molecular systems that make up living cells, tools for characterizing the interactions between the various players involved have developed. Small-angle neutron scattering (SANS) plays an important role in building a molecular-level understanding of…
The aim of this research was to study the electrical conductivity for electrical conductivity of chlorophyll with polythiophene (PT) thin film on indium tin oxide as P‐N heterojunction solar cell. The polythiophene thin film is deposited to the Indium Tin Oxide (ITO) substrate using electrochemistry method. The chloro…
-doped (GDC) thin-film electrolytes with lateral-type electrode geometry for integrated single-chamber solid oxide fuel cells (SOFCs) were prepared by dc/radio-frequency reactive magnetron sputtering. The morphological and electrical properties of the GDC films with various electrode geometries were characterized by X…
To identify the potent source of protease that can be used as ideal milk clotting enzyme(s) in handmade dairy products of latex obtained from twenty one plant species belonging to Northern (Khandesh) region of Maharashtra, India, was analyzed for caseinolytic activity, milk clotting activity, gelatinolytic activity an…
