Understanding and modulating the interaction between various reactive molecules and oxygen carriers are the key issue to achieve process intensification of chemical looping technology.C1 chemical molecules play an important role in many reactions involved with chemical looping ***,up to now,there is still a lack of systematic and in-depth understanding of the adsorption mechanism of C1 molecules on the surface of oxygen carriers(OCs).In this work,the intrinsic interaction between a series of C1 molecules composed of CH4,CO,CO2,CH3OH,HCHO and HCOOH and surface of Ni O OCs in the chemical looping process have been studied using density functional theory *** adsorption configurations of C1 molecules and also different adsorption sites of Ni O have been *** structural features of stable configuration of C1 molecules on the surface of NiO OCs have been ***,the interacted sites,types and strengths of C1 molecules on the surface of NiO have been directly pictured by the independent gradient model ***,the nature of the interaction between C1 molecule and Ni O surface has been investigated with the aid of energy decomposition analysis from a quantitative view.

传统委托计算中,由于参与者双方的自利行为,存在委托方抵赖和计算方不诚实计算等问题。在支付阶段,需采用第三方来保证支付的公平性,从而导致额外的开销且存在泄露参与者隐私的风险。利用博弈论分析了支付过程中双方达到纳什均衡解,提出一种基于比特币时间承诺的公平支付协议。首先,利用比特币时间承诺技术保证参与者支付的公平性;其次,利用区块链去中心化的特性来取代第三方服务保护各方隐私且实现责任溯源;最后从安全性和正确性对方案进行分析,证明了参与者在支付过程中诚实选择行为策略。所提方案不仅解决了传统委托计算中公平支付的难题而且保护了参与方的隐私。
