In order to improve the performance and endurance of steel rings used for twisting and winding yarns in the textile industry, a\nmore wear-resistant ceramic version is studied and examined by conducting multiple simulations combined with microwave\nsintering experiments of the ring preparation process, aiming to reduce manufacturing costs and improve efficiency. The threedimensional\n(3D) electromagnetic field simulation software HFSS is used to simulate the electromagnetic field distribution in the\nmicrowave sintering cavity and to determine the electromagnetic region with the most uniform electromagnetic field to guide the\nmicrowave sintering experiments. The 3Y-TZP ceramic rings are shaped by gel-casting. The effect of presintering on the\nperformance of ceramic rings is investigated by applying conventional sintering and microwave sintering methods. The experimental\nresults show that the simulation-guided microwave sintering process can resolve the deficiency of uneven microwave\nsintering at low temperatures....
This work is aimed at improving the electrosorption capacity of carbon nanotube/reticulated vitreous carbon- (CNT/RVC-) based\n3D electrodes and decreasing the duration of electrosorption-desorption cycles by facilitating the ionsâ?? adsorption and desorption\non the electrode surface. This was achieved by preparing composites of microwave-irradiated graphene oxide (mwGO) with CNT.\nAll composite materials were coated on RVC by the dip-coating method. The highest loading level was 50 mg. This is because it\nexhibited the maximum electrosorption capacity when tested in terms of geometric volume....
As a newly proposed high resolution computational imaging technique, Microwave Staring\nCorrelated Imaging (MSCI) requires elaborate design of the temporal-spatial stochastic radiation fields\n(TSSRF). Conventional implementation of MSCI radiation source consists of multiple transmitters\nconfiguration and simultaneous emitting scheme, which remains underutilization of the available\ndesign resources. In this paper, a time-division MSCI (TD-MSCI) method is proposed to virtually\ngenerate the TSSRF and make further use of the available design resources. Different from convention\nsimultaneously transmitting based MSCI, the detection scheme in TD-MSCI is achieved by alternately\ntransmitting of each transmitter, rather than simultaneous transmission of multiple transmitters.\nEcho enhancement is conducted to improve the SNR level of the echo waveform and to resolve\nthe power coastdown caused by single transmitting scheme....
