We have newly developed an electron energy analyzer FESA (Fast Electron energy Spectrum Analyzer) for a future magnetospheric satellite mission SCOPE. The SCOPE mission is designed in order that observational studies from the cross‐scale coupling viewpoint are enabled. One of the key observations necessary for the SCO…
This study reports an investigation of the effect of carburizing variables -temperature, time and percentage of energizer -on the case properties of C2R steel obtained from HMT Ltd. India. A carburizer consisting of hardwood charcoal and coke respectively in the ratio of 2:1 was used for the research with sodium carbo…
Cathodic Protection is one of the method to Control Corrosion rate thermodynamically by applying steel as cathode. Application of this methode is by flow the DC current through electrolite to steel so that potential interface between steel and electrolite goes to immun area or until paricular value which corrosion spe…
The double‐doped CaF2:(0.14 mol% ErF3,1.31 mol% YbF3) and CaF2:0.12 mol% ErF3 crystals were grown in our crystal research laboratory using the vertical Bridgman method. The Judd‐Ofelt intensity parameters Ω2, Ω4, and Ω6 for f−f transitions of Er3+ ions were determined from the optical absorption spectra using various…
Architecturally, the conventional attachment of photovoltaic (PV) systems to buildings can often generate aesthetically displeasing results. New innovative materials and techniques are needed to facilitate the widespread use of building integrated PV façades further. Implementing and testing bonded joints in glass con…
Edible soy protein isolate (SPI)-based films were prepared using hot film-forming solutions containing SPI, glycerol and either glucose or sucrose. As a result of the Maillard reaction SPI/glucose films were darker, higher in tensile strength, lower in water vapour transmission rate, oxygen gas transmission rate, solu…
The IJkdijk project is an international test site for inspection and monitoring techniques for levees. The objectives are two-fold: firstly, to develop and validate new sensor techniques and secondly to perform full-scale failure experiments on levees to understand fundamental behaviour in order to be able to increase…

A dynamic punch test is introduced. The test is conducted by placing a punching assembly between the incident and transmitter bars of a compression split Hopkinson bar apparatus. The punch has a rounded nose that penetrates into the specimen (a thin round, flat, plate restricted around the circumference). The force of…
"Polyvinyl alcohol (PVA) films blend with phosphoric acid (PA) were obtained by annealing for different times and acid concentrations. The films turn brownish and darken as time processing and acid concentration increase, which is associated to the polyene formation. IR analyses disclose the evolution of the samples a…
ZnO:Ni films with different doping concentrations （0—7at.%） have been deposited by radio frequency magnetron sputtering. The results of x-ray diffraction, including θ-2θ mode and rocking curve mode, indicate that the film doped with 5at.% Ni shows an excellent preferred growth along c-axis orientation. The （002） diffr…
With H2C2O4·2H2O and Zn(Ac)2·2H2O as raw materials,the precursor ZnC2O4·2H2O is synthesized by solid-phase reaction at room temperature,nanometer ZnO is obtained by decomposing the precursor at 460℃ for 2h and then modified respectively using sodium dodecyl benzene sulfonate and sodium stearate.The properties of the p…
Carbonyl iron/epoxy-silicone coating is prepared by using carbonyl iron powder as absorber and epoxy-silicone resins as matrix. The effects of the carbonyl iron powder amount on the electromagnetic and mechanical properties of coating are investigated. The results indicate that there is good bonding state of carbonyl…
Saskatchewan's potash producing companies are now in the process of developing decommissioning and reclamation (D&R) plans for potash mines which were in operation many years before these plans were required by provincial regulations. The major problem is to develop a plan for the extensive piles of potash tails n…
ZnO nanorods and thin films were synthesized on Si(100) substrates at a low temperature by controlling the ZnO seed formation in an aqueous solution process. Vertically well-aligned ZnO nanorods with a single-crystalline hexagonal structure and c-axis growth orientation were obtained despite having a different crystal…
In this work anion-exchange properties of polyaniline-coated silica gel for some of anion phosphates such as, sodium, disodium hydrogen, ammonium and magnesium phosphates were investigated qualitatively and quantitatively. The concentration effects of anion phosphates and flow rates were also investigated and kinetic…
A rigorous program of type and routine testing is applied before and during the manufacturing of high voltage (HV) hydro generator stator windings. The purpose of type tests is to qualify the insulation system as suitable for its purpose, and the purpose of routine production testing is to ensure there are no manufact…
A hyperbranched polymer (HBPO–PCL) consisting of a hyperbranched polyether (HBPO) inner core and biodegradable poly(ε-caprolactone) (PCL) shell was synthesized and used as the host for molecular encapsulation. A water-soluble dye (acid orange 7, AO 7) was selected as the corresponding guest molecule. Due to the hyperb…
The long-term performance of ferritic/martensitic steel T91 and austenitic 316L in oxygen-containing flowing lead-bismuth eutectic at 550°C was investigated by exposing the materials for up to 15000 h in the CORRIDA loop. The velocity of the liquid-metal flow was 2 m/s and the concentration of dissolved oxygen average…
Achenbach-Seelecke model for shape memory alloys is able to address full thermomechanical coupling of mechanical and thermal fields. The model roots in a stringent interpretation of thermodynamical principles and interprets the behavior as resulting from an interplay of austenite with two generic martensite twin varia…
