The clinical applications of tissue engineering are still limited by the lack of a functional vascular supply in tissue-engineered constructs. In order to improve the pre-vascularization of tissue-engineered scaffold during in vitro culture, in this study, based on three-dimensional (3D) printing technology, using the…
In order to improve the anti-corrosion characteristic of Ag-coated 316SS bipolar plates in PEMFC environment, self-assembled monolayer (SAM) was prepared on its surface by chemical methods. The electrochemical characteristic of modified bipolar plate was also investigated. The results indicated that the SAM was compos…
The concept of the macromolecular structure of solids and quantitative estimation of surface reactivity using inductive constants is applied to the estimate of surface nanostructures on dispersed and single-crystal matrices. The possibilities of the proposed approach are demonstrated by the example of the synthesis of…
New dielectric metamaterial based on the Bragg filter comprising ten dielectric bilayers was investigated. Each bilayer is the thin films of silicone dioxide (SiO2) and another film of zirconium dioxide (ZrO2). The surface of the multilayer film is profiled. It has a form of periodic system of rectangles separated by…
In view of the difficulty of manufacturing titanium alloy tubes, a U–O forming process was proposed to manufacture tubes with TA15 titanium alloy. The effect of the U–O forming process on the microstructure evolution of typical regions of TA15 tubes was investigated using electron backscattered diffraction technique.…
In this work, we present the recent work on self-forming barriers. Focus on investigation laid on the barrier formation and its stability against copper diffusion. The investigated alloys were Cu(Mn), Cu(Ti) and Cu(Zr) respectively. It can be shown that these alloys are capable to form an enrichment layer on the SiO2i…
A dual-side cooling topology is proposed that is achieved by embedding a power insert into the organic substrate of a chip or chip stack. The power insert consists of vertical copper lamellas supporting lateral current feed in addition to vertical heat dissipation at minimal electrical and thermal gradients. The later…
In case of transformer failure there is a high risk of losing part of power system, which can result in disruption for consumer power supply. This is main reason for power transformer protection requirement to be so high. Power transformer is a complicated object considering its protection. Sensitivity level is a key…
The power cable has been widely used for decades. As an important accessory of power cable, the cable joint is the weak link because of site installation conditions. Partial discharge and insulation aging in it cause temperature rise, which may lead to explosion of the cable joint in serious conditions. There are many…
The microstructure and the mechanical properties of Mo–Cu alloys fabricated by mechanical alloying and vacuum sintering from mixed elemental powders were investigated. The activating element of Fe improved the Archimedes density of the Mo–20 (wt-%)–Cu alloy. The results showed that the Mo–20Cu alloy with 0·7 wt-% Fe c…
The use of thin polyaniline films for solar cell development, effective electron field emission and organic field-effect transistors was investigated. The solar cells based on binary donor-acceptor systems in the form of a combination of polyanilines with fullerene-containing polymers were developed and researched. Th…
“Hard” piezoelectric materials of Fe modified 0.37BiScO3-0.6PbTiO3-0.03Pb(Mn1/3Nb2/3)O3(BS-PT-PMN-Fe) ceramics were prepared by traditional solid state reaction method. X-ray diffraction (XRD) analysis revealed that BS-PT-PMN-Fe ceramics showed single perovskite structure with dominant tetragonal phase, and the c/a ra…
Superhydrophobic cathodic cobalt and anodic copper surfaces were fabricated by one-step electrodeposition process. The superhydrophobicity properties, morphological features and chemical composition of the coatings were characterised. The results show that a short time of 0·5 minute is sufficient to render superhydrop…
The use of temporary implants, which is widely diffused in orthopedic surgery requires surgical procedures to remove the implants after bone healing. A bioresorbable implant, which does not need to be surgically removed, would reduce both patient morbidity and risks of future diseases. Thanks to their biocompatibility…
Plasma-assisted molecular beam epitaxy (PAMBE) growth of ultra-thin Al0.2Ga0.8N/GaN heterostructures on Si(111) substrate with three buffer thickness (600 nm/400 nm/200 nm) have been reported. An unique growth process has been developed that supports lower temperature epitaxy of GaN buffer which minimizes thermally ge…
The objective of this work was to study the interphase precipitation of carbides during isothermal transformation at 750°C after being deformed at 900°C in Ti bearing steels. The effects of isothermal time on the microstructures and precipitation behaviours have been investigated using optical microscopy, transmission…
A 2D-3D hybrid finite element method (FEM) approach is proposed for fast analysis of eddy current loss in magnets of permanent magnetic synchronous motors (PMSM) driven by a pulse width modulation (PWM) inverter. A voltage-source PWM inverter circuit coupled 3D FEM model of a PMSM was built with the commercial FEM cod…
Heat assisted magnetic recording (HAMR) is a likely candidate for achieving higher areal densities in future magnetic recording technologies [1]. HAMR employs the use of a laser and near field optical transducer to locally heat the medium, such that the magnetic field required for writing is reduced. This is required…
To deal with the soil polluted by radioactive nuclide Cs like that in Fukushima, Japan. As pollucite evolves via analcime into clay mineral finally in nature, the analcime and final pollucite should be synthesized from clay minerals. A hydrothermal technology has been applied to synthesize rock to immobilize radioacti…
Because of the high saturation magnetization (μ0Ms=1.6 T) and high magnetocrystalline anisotropy (Ku=4.5 MJ/m3) of the Nd2Fe14B phase, anisotropic Nd-Fe-B sintered magnets exhibit the highest energy product (474 kJ/m) of all the permanent magnetic materials. However, the issue on substitution of Pr-Nd or Nd by Ce attr…
