This article took the sodium sulfate and calcium chloride as the raw material and prepared calcium sulfate whiskers by hydrothermal method. The experimental results show that the calcium sulfate precursors are prepared by the reverse feed mode in which the sodium sulfate solution drop into the calcium chloride solutio…
C/SiC composites have widely application prospects in the field of aeronautic and aerospace for their excellent properties. The joining of C/SiC composites is a key to fabricate large and complex components. In this paper, 1D C/SiC pins were prepared by precursor infiltration and pyrolysis (PIP) process and used to jo…
This paper reports the tailoring thermal conductivity of novel dense vertical and horizontal graphene (DVHG) structures, which we previously discovered. By removing horizontal graphene layers, resulting in forming vertical graphene contacts to the electrode, we not only improved the thermal conductivity by a factor of…
Single crystals of non-linear optical material, L-Serine Sodium Nitrate (LSSN) have been grown by slow evaporation technique. The crystal system and lattice parameters were found from single crystal X-ray diffraction. Some fundamental data such as valance electron plasma energy, Penn gap, Fermi energy and electronic p…
Abstract Kinetic behaviour and thermo-mechanical properties of composites based on unsaturated polyester (UP) resin and organically modified clay (OMC) are completely dependent on their preparation procedure. The investigation on the preparation procedure of the UP/OMC suspensions under high shear conditions alone (sh…
This paper presents a study on the effect of mineral filler on the polymer composite material based on waste products of heat and power engineering - fly ash. This type of waste products has never been used for the production of polymer-mineral composites. Depending on the type of ash, its chemical composition and its…
In semiconductor fabrication, pattern collapse of high aspect ratio structures after wet processing has been a critical issue and attracted a lot of interest. On the other hand, very little attention is spent on the potential wetting issues as feature dimensions are continuously scaled down and novel materials with di…
Polyisoprenes predominantly composed of cis-1,4-units are studied by the methods of NMR spectroscopy (600 MHz), GPC, and DSC. A comparative investigation of synthetic polyisoprene and natural rubbers shows that a small (up to 3–4 mol %) amount of polymer-chain disruptions, such as inverse additions of cis-1,4 units an…
Abstract This study presents a method of obtaining porous materials based on the rigid polyurethane foam (RPURF) as the matrix and containing thermoplastic polystyrene beads (EPS) as the fillers. In RPURF-EPS composites, the compact EPS were expanded after heating above a glass transition temperature of the EPS and ga…
Material properties, corrosion, and metal release from stainless steel powders are important factors to assess any occupational health hazards. This paper elucidates the corrosion behavior of stainless steel particles (inert-gas-atomized AISI 316L powders sized < 45μm, polished and non-polished) compared with correspo…
The corrosion inhibition characteristics of three Schiff bases used as inhibitors have been studied by quantum chemistry method at the level of DFT/B3LYP with the 6-31 + G (d, p) base sets. Quantum chemical parameters such as highest occupied molecular orbital energy (EHOMO), lowest unoccupied molecular orbital energy…
The effect of extract of cannabis plant on the corrosion of nickel in aqueous 0.5M sulphuric acid was investigated by electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization techniques. EIS measurements showed that the dissolution process of nickel occurs under activation control. Potentiodynamic…
Article MECHANICAL PULPING: Low consistency refining of mechanical pulp: Relationships between refiner operating conditions and pulp properties was published on December 1, 2012 in the journal Nordic Pulp & Paper Research Journal (volume 27, issue 5).
Ca 2 BO 3 Cl:Ce 3+ , Ca 2 BO 3 Cl:Tb 3+ , and Ca 2 BO 3 Cl:Ce 3+ , Tb 3+ phosphors are synthesized by a high temperature solid-state reaction. The emission intensity of Ce 3+ or Tb 3+ in Ca 2 BO 3 Cl is influenced by the Ce 3+ or Tb 3+ doping content, and the optimum concentrations of Ce 3+ and Tb 3+ are 0.03 mol and…
We theoretically investigate a switchable spin Hall effect of light (SHEL) in reflection for three specific dispersion relations at an air-anisotropic metamaterial interface. The displacements of horizontal and vertical polarization components vary with the incident angle at different dispersion relations. The transve…
Theoretical calculations of the magnitude and temperature variation of the measured thermal conductivity of undoped and doped GaAs nanobeams will present. The calculations have been performed by employing modified Callaway’s theoretical model. In the model, both longitudinal and transverse modes are explicitly taken i…
The taxonomical composition of epilithic diatoms was investigated at intertidal zone of Homa lagoon, Aegean sea, Turkey. The stations are located in different littoral zones of the study area and they are different from each other in terms of hydrological respect. The samples contained a mixture of forms growing on th…
We report a high-performance graphene/Si field-effect transistor fabricated via rapid chemical vapor deposition. Oligolayered graphene with a large uniform surface acts as the local gate of the graphene transistors. The scaled transconductance, gm, of the graphene transistors exceeds 3 mS/μm, and the ratio of the curr…
Hyperspectral cathodoluminescence mapping is used to examine a carbonado diamond. The hyperspectral dataset is examined using a data clustering algorithm to interpret the range of spectral shapes present within the dataset, which are related to defects within the structure of the diamond. The cathodoluminescence respo…
Abstract Summary: Segmented polyurethanes have been synthesized employing polyols derived from renewable resources, semicrystalline or amorphous in nature, as soft segment, and an aliphatic (1,6‐hexamethylene diisocyanate, HDI) or aromatic (4,4′‐diphenylmethane diisocyanate, MDI) diisocyanate and 1,4‐butanediol (BD) a…
