Periodic mesoporous titanium phosphonate (PMTP-1) materials were synthesized and used as an adsorbent for the removal of a cationic dye, methylene blue (MB), from aqueous solutions. The PMTP-1 powder has a uniform mesopore size of 2.9 nm with high surface area of 606 m 2 /g. The batch-dye adsorption experiments were p…
To prepare for projects such as the Large Hadron Collider upgrade, International Thermonuclear Experimental Reactor and Demonstration reactor, it is important to form a clear understanding of stress-strain properties of the materials that make up superconducting magnets. Thus, we have been studying the mechanical prop…
A novel braking material, C/C-ZrB 2 -ZrC-SiC carbon fibre-reinforced hybrid ceramic matrix composite, was prepared by chemical vapour infiltration and polymeric precursor infiltration and pyrolysis. Investigation of the microstructure of C/C-ZrB 2 -ZrC-SiC composite showed the homogenous dispersion of three-phase cera…
We have measured and compared surface roughness and the degree of damage for wafers cut by three different sawing techniques - slurry, Ni-based diamond wire, and resin-based diamond wire sawing. The local damage was determined by angle polishing followed by defect etching, TEM, SEM/EBSD imaging and Raman imaging. It s…
Internet traffic has been exponentially growing with the increasing demand of content dissemination. This explosive growth in traffic poses a significant challenge to the networks, especially backbones. To address the challenge, the emerging content-oriented Named Data Networking (NDN) has been proposed due to its att…
The production/consumption of greenhouse gases (GHG) in soils are of great importance in global warming, but the involved soil physico-chemical and biological characteristics affecting GHG production and consumption potentials are poorly understood in different land-use types. Carbon dioxide (CO2), nitrous oxide (N2O)…
The Central Solenoid (CS) is a critical component in the ITER tokamak providing plasma current drive and shaping. The CS final design is being completed at the US ITER Project Office (USIPO) in Oak Ridge, TN under a Procurement Arrangement with the ITER Organization (IO). Key design decisions have been made and CAD mo…
HTR50S is a small modular reactor system based on HTGR. It is designed for a triad of applications to be implemented in successive stages. In the first stage, a base plant for heat and power is constructed of the fuel proven in JAEA's 950°C, 30MWt test reactor HTTR and a conventional steam turbine to minimize developm…
A broadband gain enhancement endfire antenna is presented. The gain enhancement is achieved by loading with an I‐shaped resonator (ISR) structure in the endfire direction. Broad bandwidth is realised by using a microstrip‐to‐coplanar balun and bowtie dipole elements, while gain enhancement is achieved by loading the I…
Vapor-deposited molybdenum oxide films are used as low resistance anode interfacial layers in applications such as organic light emitting diodes (OLEDs) and organic photovoltaics (OPVs). A versatile method for the vapor deposition of molybdenum oxide layers is presented, which offers the control of the oxygen stoichio…
In the present study, the casting method has been utilized for preparing different concentrations of Rhodamine B (Rh-B) doped in different transparent polymers. The spectral characteristics of the prepared samples are studied by absorption and fluorescence spectroscopy. The optical absorption measurements have been ca…
The concept and analysis of a graphene-metal reconfigurable terahertz dipole antenna are presented. The hybrid graphene-metal implementation is proposed to combine i) dynamic frequency reconfiguration using graphene field effect and ii) high radiation efficiency enabled by metal. The good direct matching to terahertz…
In this paper, an air homogenous dielectric barrier discharge excited by bipolar nanosecond pulse voltage is obtained and used for the surface modification of polypropylene non-woven fabric at atmospheric pressure. Compared with the DBD plasma excited by sine alternating current (AC) voltage, nanosecond pulsed dielect…
Endoluminal and catheter-based ultrasound applicators are currently under development and are in clinical use for minimally invasive hyperthermia and thermal ablation of various tissue targets. Computational models play a critical role in device design and optimisation, assessment of therapeutic feasibility and safety…
The oil producing and petroleum refining industries dispose of a significant amount of oily sludge annually. The sludge typically contains a mixture of oil, water and solid particles in the form of complex slurry. The oil in the waste sludge is inextractible due to the complex composition and complex interactions in t…
Araucaria angustifolia (Bert.) O. Kuntze is the main component of the Mixed Ombrophilous forest and, in the State of São Paulo, it is associated with a high diversity of soil organisms, essential for the maintenance of soil quality, making the conservation of this ecosystem a major and pressing challenge. The objectiv…
Polymer electrolytes composed of a blend of poly(vinyl chloride)–poly(ethylene oxide) (PVC/PEO) as a host polymer, lithium triflate (LiCF3SO3) as a salt, mixture of ethylene carbonate (EC) and dibuthyl phthalate (DBP) as plasticizers and silica (SiO2) as the nanocomposite filler were studied. The variation in ionic co…
The micro-exon genes (MEG) of Schistosoma mansoni, a parasite responsible for the second most widely spread tropical disease, code for small secreted proteins with sequences unique to the Schistosoma genera. Bioinformatics analyses suggest the soluble domain of the MEG-14 protein will be largely disordered, and using…
This paper presents an experimental study on the impact of anchor losses on the quality factor (Q) of laterally vibrating AlN contour mode resonators for three different resonance frequency devices (220 MHz, 370 MHz, and 1.05 GHz). Anchors of different width (Wa) and length (La) were designed as supports for resonator…
First-principles calculations within generalized gradient approximation have been performed to investigate ideal strengths of anti-fluorite structured Mg2X (X = Si, Ge, Sn and Pb) compounds. The present calculations showed that the ideal tensile strengths of Mg2X occur in the [111] directions while the ideal shear str…
