Using a simple and precise instrument system, we directly measured the thermo-physical properties of one-dimensional highly aligned carbon nanotubes (CNTs). A kind of CNT-based macroscopic materials named super aligned carbon nanotube (SACNT) buckypapers was measured in our experiment. We defined a new one-dimensional…
The mechanical behaviour of the commercial aluminium alloys EN AW-5182, EN AW-6016 and EN AW-7021 is investigated at temperatures ranging from 298 to 77 K and strain rates from 1.7 × 10 −3 to 6.6 × 10 −2 s −1 . A device that allows testing at cryogenic temperatures is developed and demonstrated, where the specimens ar…
Herein, we report evidence for the promising potential of 2-(acetylthio)ethylmethacrytale (AcSEMA), a new monomer, which copolymerizes with methyl methacrylate (MMA) by atom transfer radical polymerization (ATRP) leading to well-defined multidentate protected thiol polymer ligands for CdSe QDs capping by simple ligand…
Cross-linked poly(butylene succinate) (PBS) was prepared by the reactions of the end hydroxyl groups of PBS with toluene diisocyanate and trimethylolpropane (TDI–TMP) polyurethane prepolymer at the processing temperature. The effects of varied TDI–TMP prepolymers on properties such as mechanical properties, thermal pr…
The thermodynamic and geometric parameters of M(II) macrotetracyclic chelates (M = Mn, Fe, Co, Ni, Cu, and Zn) with the (NNNN) coordination of the donor ligand sites, formed by the complexation reactions of corresponding M(II) compounds, ethanedithioamide H 2 N-C(=S)-C(=S)-NH 2 , and acetone H 3 C-C(=O)-CH 3 in gelati…
The employment of Ni–Mo films has recently been shown to yield strictly homogeneous single-layer graphene. In this study, we systematically investigate the different stages of nucleation and growth of graphene over Ni–Mo layers. The studies reveal that the Ni film breaks up and diffuses into the underlying Mo foil, fo…
Ultra-broadband emission covering 1000?1800 and 1800?3020?nm of Bi2O3?GeO2 binary system materials, from glass to glass-ceramics to crystals, is presented in this paper. This is the first time, to our best knowledge, that broadband photoluminescence of BGO crystals (including Bi4Ge3O12 and Bi12GeO20) in the range of 1…
The role of carbon additions and oxygen content on the densification of zirconium diboride ( ZrB 2 ) was studied. ZrB 2 with up to 1 wt% added carbon was hot pressed at temperatures of 2000°C and 2100°C. Nominally pure ZrB 2 hot pressed at 2100°C achieved relative densities >95.5%. Carbon and oxygen analysis indica…
GeO2 transparent glass ceramic planar waveguides were fabricated by a RF-sputtering technique and then irradiated by a pulsed CO2 laser. The effects of CO2 laser processing on the optical and structural properties of the waveguides were evaluated by different techniques including m-line, micro-Raman spectroscopy, atom…
The temperature evolution of structural effects associated with charge order (CO) and spin order in La1.67Sr0.33NiO4 has been investigated using neutron powder diffraction. We report an anomalous shrinking of the c/a lattice parameter ratio that correlates with T(CO). The sign of this change can be explained by the ch…
Zn-based nanostructured Ba0.05Cu0.25Fe0.10Zn0.60O (BCFZ) oxide electrode material was synthesized by solid-state reaction for low-temperature solid oxide fuel cell. The cell was fabricated by sandwiching NK-CDC electrolyte between BCFZ electrodes by dry press technique, and its performance was assessed. The maximum po…
To activate a catalyst efficiently at low temperature by plasma for environmental control, we developed a hybrid reactor that combines plasma with a honeycomb-structured catalyst in a practical manner. The reactor developed generated stable cold plasma at atmospheric pressure because of the dielectric and conductive n…
Neutron scattering and magnetometry measurements have been used to study phase transitions in LaCoO3 (LCO). For H ≤ 100 Oe, evidence for a ferromagnetic (FM) transition is observed at Tc ≈ 87 K. For 1 kOe ≤ H ≤ 60 kOe, no transition is apparent. For all H, Curie-Weiss analysis shows predominantly antiferromagnetic (AF…
Stronger regulations on nitrogen oxide (NOx) production have recently promoted the creation of a diverse array of technologies for NOx reduction, particularly within the combustion process, where reduction is least expensive. In this paper, we discuss a new combustion technology that can reduce NOx emissions within in…
Physical principals and the relations between Surface Plasmon Resonance (SPR) spectra and geometrical properties of metal nanostructures specially silver and gold were reported. Applying SPR technique enable us to investigate the accuracy of some simple equations for investigating geometrical properties of metal nanos…
Cerium oxide or ceria is an inorganic compound of Cerium, a rare earth element of lanthanide series. Due to the unique ability of cerium to switch oxidation states between +3 and +4 it has various applications as ultraviolet light absorbers, catalytic converters for automobile exhaust systems, solar cells, optics, oxy…
The random non-standard peptide integrated discovery (RaPID) system has proven to be a powerful approach to discover de novo natural product-like macrocyclic peptides that inhibit protein functions. We have recently reported three macrocyclic peptides that bind to Pyrococcus furiosus multidrug and toxic compound extru…
This paper focuses on the design of natural fiber composites and analysis of multiaxial stresses in relation to yield limit stresses of composites loaded off the fibers axis. ASTM D638-10 standard for tensile test was used to design and compose composites of plantain fiber reinforced polyester (PFRP). While the rule o…
First-principles calculations are performed to investigate structural and magnetic behaviors of rare-earth orthochromates as a function of 'chemical' pressure (that is, the rare-earth ionic radius), epitaxial misfit strain and hydrostatic pressure. From a structural point of view, (i) 'chemical' pressure significantly…
The oxidative chemistry of graphite has been investigated for over 150 years and has attracted renewed interest given the importance of exfoliated graphene oxide as a precursor to chemically derived graphene. However, the bond connectivities, steric orientations, and spatial distribution of functional groups remain to…
