Degradation of molybdenum disulfide through cascade reactions with hydrogen peroxide in aqueous system.

Transformation is a crucial process determining the lifespan and risk of MoS nanomaterial during usage and after disposal. This study revealed the degradation of MoS in the presence of HO using experimental and computational methods. Experimental results showed that MoS nanosheets were degraded by 45.

[Study on regurgitation using the coupling model of left ventricular assist device and cardiovascular system].

Regurgitation is an abnormal condition happens when left ventricular assist devices (LVADs) operated at a low speed, which causes LVAD to fail to assist natural blood-pumping by heart and thus affects patients' health. According to the degree of regurgitation, three LVAD's regurgitation states were identified in this paper: no regurgitation, slight regurgitation and severe regurgitation. Regurgitation index ( ), which is presented based on the theory of dynamic closed cavity, is used to grade the regurgitation of LVAD.
