Materials science can pave the way toward developing novel devices at the service of human life. In recent years, computational materials engineering has been promising in predicting material performance prior to the experiments. Herein, this capability has been carefully employed to tackle severe problems associated with kidney diseases through proposing novel nanolayers to adsorb urea and accordingly causing the wearable artificial kidney (WAK) to be viable. The two-dimensional metal carbide and nitride (MXene) nanosheets can leverage the performance of various devices since they are highly tunable along with fascinating surface chemistry properties. In this study, molecular dynamics (MD) simulations were exploited to investigate the interactions between urea and different MXene nanosheets. To this end, detailed analyses were performed that clarify the suitability of these nanostructures in urea adsorption. The atomistic simulations were carried out on MnC, CdC, CuC, TiC, WC, TaC, and urea to determine the most appropriate urea-removing adsorbent. It was found that CdC was more efficient followed by MnC, which can be effectively exploited in WAK devices at the service of human health.
材料科学可为开发服务于人类生活的新型设备铺平道路。近年来,计算材料工程在实验之前预测材料性能方面颇具前景。在此,通过提出新型纳米层来吸附尿素,从而使可穿戴人工肾(WAK)可行,这种能力已被谨慎用于解决与肾脏疾病相关的严峻问题。二维金属碳化物和氮化物(MXene)纳米片因其具有高度可调节性以及迷人的表面化学性质,能够提升各种设备的性能。在本研究中,利用分子动力学(MD)模拟来研究尿素与不同MXene纳米片之间的相互作用。为此,进行了详细分析,以阐明这些纳米结构在尿素吸附方面的适用性。对MnC、CdC、CuC、TiC、WC、TaC和尿素进行了原子模拟,以确定最合适的尿素去除吸附剂。结果发现,CdC效率更高,其次是MnC,它们可有效应用于服务人类健康的WAK设备中。
