Smectite illite (I/S) transformation is part of lithification process of fine grained sediments. We constructed and calibrated a coupled kinetic I/S transformation and mechanical compaction model in which Arrhenius equation describing the rate of transformation and I/S grains collapse accounting for porosity reduction…
Until now, the evaluation method of spalling depth using Martin et al. (1999)'s linear regression relations has long been known applicable. However, it is not likely that the proposed equation is applicable to the openings other than circular type and mostly overpredict the spalling depth in comparison with actual spa…
Titanium alloys, due to their biocompatibility and low stiffness, are among the most studied of metallic implant materials. Whereas most titanium-based biomaterials are produced from prealloyed powders, in this work the authors have utilised elemental powder to manufacture porous Ti-Nb-Ta-Zr alloys using a powder meta…
The selective CO methanation (CO-SMET) process via Ru–Al2O3 catalysts was investigated as a tool for complete CO removal in fuel processors, when the H2-rich gas so produced is employed for PEM-FCs applications to vehicles, boats, yachts and residential co-generators. CO-SMET seems, in fact, to be a good alternative t…
This chapter reviews antioxidant active packaging for food. It introduces, reviews and comments upon the state of the art, as well as discussing the principles of antioxidant packaging and antioxidant edible films, and the available systems for measuring the antioxidant capacity of these packaging materials. The chapt…
The important topic of temporal soliton propagation in double-negative metamaterials is discussed with an emphasis upon short pulses that exhibit self-steepening controlled by the frequency dependence of the relative permittivity and permeability. In addition, magnetooptic control is included, leading to some fascinat…
This Thesis is focused on the preparation of novel functional metal-oxide nanocomposite films by solution-based deposition methodologies. One of the most outstanding results of this work is the capability to prepare epitaxial nanocomposite films with embedded randomly oriented nanoparticles leading to the formation of…

采用溶胶-凝胶法在304不锈钢表面制备了铈掺杂TiO2薄膜,并采用半连续培养方式在海水中培养硫酸盐还原菌（SRB）。通过形貌观察及电化学方法研究浸泡于菌液中的空白304不锈钢及铈掺杂TiO2/304ss电极的腐蚀行为。结果指出,在304不锈钢表面涂覆铈掺杂TiO2薄膜后能显著抑制硫酸盐还原菌的附着行为;涂膜电极在硫酸盐还原菌菌液中的自腐蚀电流密度低于同期浸泡的空白304不锈钢电极,而电化学阻抗值则高于同期浸泡的空白304不锈钢电极,表明在304不锈钢表面涂覆铈掺杂TiO2薄膜能起到抗海水中硫酸盐还原菌附着腐蚀的作用。 更多还原
For this chapter, we have collated from the authors in this book approaches and techniques for the quantification and qualification of biofouling and have presented most of it in referenced tabular form to permit easy access to the information (Table 22.1). There are also two more thorough sections neither of which ha…
Aims: To compare the mean shear bonding force and mode of bond failure of metallic brackets bonded and rebounded (using new and pre-used brackets) to sandblasted and acid-etched enamel is described. Materials and methods: The buccal surfaces of 40 extracted human premolars were sandblasted for 5 seconds with 50 μ alum…
A systematic study of four parameters within the alkaline hydrothermal treatment of three commercial titania powders—anatase, rutile, and Degussa P25—was made. These powders were treated with 5, 7.5, 9, and 10 M NaOH between 100 and 220 °C for 20 h. The effects of alkaline concentration, hydrothermal temperature, and…
Si/graphene composite was prepared by simply mixing of commercially available nanosize Si and graphene. Electrochemical tests show that the Si/graphene composite maintains a capacity of 1168 mAh g-1 and an average coulombic efficiency of 93% up to 30 cycles. EIS indicates that the Si/graphene composite electrode has l…
Successful implantation of any biomaterial depends on its mechanical, architectural, and surface properties. Materials with good bulk properties seldom possess the appropriate surface characteristics required or good biointegration. The present study investigates the results of surface modification of a highly porous,…
Structural reliability is a hurdle for the large-scale commercialisation of solid oxide fuel cell (SOFC). The cells are prone to cracking, due to the brittleness of their constitutive materials. In operation, the failure of one of them can arise from the non-uniform temperature distribution, coupled to detrimental int…
The phase-field model coupled with a flow field was used to simulate the solidification of pure materials by the finite difference method.The effects of initial crystal radius,the space step and the interface thickness on the dendrite growth were studied.Results indicate that the grain grows into an equiaxial dendrite…
Amine-functionalized and amine-carboxylate double-functionalized polymers (I and II, respectively) have been synthesized by a selective single addition of a protected 2-aminoethyl vinyl ether (BocVE) {CH₂ = CH[OCH₂CH₂N(Boc)₂]; Boc = t-butoxycarbonyl} onto a living cationic poly(n-butyl vinyl ether) [poly(NBVE)] initia…
The effect of ecap and grain size on corrosion resistance of AA 2024-T3
A comprehensive consideration of loading effects is essential to the design/analysis of high-frequency MRI radio frequency (RF) coils. In this study, a hybrid finite difference time domain (FDTD)-method of moments (MoM) simulation method is implemented for the accurate evaluation of RF coil-tissue interaction. Using t…
We report on the reduction of the threading edge dislocation density of Al 0.15 Ga 0.85 N buffer layers for efficient 350nm light-emitting diodes (LEDs). Structures were grown by metalorganic vapor phase epitaxy (MOVPE) on (0001) sapphire substrates using three-dimensional (3D) facetted GaN nucleation islands. The fla…
