Porous graphitic carbon sheets grafted on microfibers were synthesized with the aid of a green activating–graphitizing agent K<sub>3</sub>[Fe(C<sub>2</sub>O<sub>4</sub>)<sub>3</sub>].
In this study, we have introduced gelcasting for prepared near-shape porous Ti-Mo and Ti-Nb alloys implants. The microstructure the total porosity of vacuum sintered Ti were analyzed by using electronic microscopy (SEM) X-ray diffraction (XRD). Moreover, compression bending tests conducted to investigate their mechanical properties. results shows that three-dimensional pore morphologies range from 39% 50% can be achieved. Ti-Nab contained a mixture α β phase. compressive strength was...
ABSTRACT In recent years, some Cu‐based complexes and nanomaterials that can better adapt to tumour microenvironments produce chemodynamic therapeutic effects have been synthesised. Ferrocene its derivatives garnered increasing attention as a option in therapy owing their excellent catalytic activity. Herein, two ferrocene‐modified Cu(I) complexes, Fc‐ AD ‐Cu Fc‐IH‐Cu , were synthesised with atomically precise structures. Both exhibit good Fenton/Fenton‐like activity, inducing the generation...
Porous titanium alloys have been prepared by gelcasting in this study. The elastic solid green body was first polymerized and then vacuum sintered to porous with low contamination controlling sintering conditions. microstructure the total porosity of Ti-Co Ti–Mo were analyzed using scanning electron microscopy x-ray diffraction. Moreover, compression bending tests conducted investigate their mechanical properties. results show that open closed three-dimensional pore morphologies ranging from...
A setup based on dynamic method was developed for fast Seebeck coefficient measurement from room temperature to 473 K. Two T-type thermocouples with a response time of less than 0.1 s were used measure the temperatures sample. The Cu wires two served as leads voltage measurement. feature characterized. Test measurements conducted LaCo0.9Cu0.1O3 and LaCo0.85Cu0.15O3 samples customized setup, results had difference ±8.4% compared data provided by ZEM-2 (Ulvac-Riko, Japan), which showed that...
We have prepared spherical Ti–6Al–4 V (TC4) alloy powder by radio frequency (RF) plasma with irregular TC4 for obtaining the stable suspension slurry. The results showed that fine powders smooth surface and favorable dispersion were obtained spheroidization efficiency of was almost 100%. solid loading slurry using greatly improved to 63 vol.% compared 40 powder, at which viscosity is lower than 1 Paás. green bodies bending strength 20 MPa had a surface.
BEA-type core–shell catalysts consisting of a core supporting Cu and Fe Ni-based shell were investigated for their ethanol steam reforming (ESR) activity.
Purpose Low-Ag SAC solder will lead to a series of problems, such as increased the melting range and declined solderability so on. These research studies do not have too much impact on improvement solders’ performance but were difficult achieve satisfactory results. It is urgent develop new soldering technology avoid bottleneck lead-free solder. low-temperature-stirring ultrasonic-assisted was developed in authors’ early work, slag inclusion pore would gather grow up decreasing shear...
Purpose With continuous concerning on the toxic of element Pb, Pb-free solder was gradually used to replace traditional Sn-Pb solder. However, during transition period from solder, mixing and is inevitable occurred in certain products, China where still extensively areas especially. Correspondingly, understanding reliability joints very important, further studies were needed. Design/methodology/approach Thermal shock test between −55°C 125 °C conducted Sn-37Pb bumps BGA package investigate...
The wettability of the molten lead-free solder on substrate is an important property for joints in electronic products. In this paper, we investigated pastes electroplated Co-P films. We measured contact angles one kind Sn-Bi and two kinds Sn-Ag-Cu (SAC305 SAC387) films with nanocrystalline, amorphous mixed structures studied dependence solders microstructure film. experimental data showed that general film a large phosphorous content was favorable all three terms wettability. SAC305 had...
