Mechanisms behind the environmental sensitivity.of carbon fiber reinforced p.ly.etrafluoroethy.ene(p.FE)

引用

Friction 2024年第5期12卷 997-1015页

作者： p.ntus JOHANSSON p.MARKLUND M.BJORLING y.SHI Division of Machine Element LuleåUniversity of TechnologyLuleåSE-97187Sweden

Carbon fiber reinforced p.ly.etrafluoroethy.ene (CF/p.FE) comp.sites are known for their excep.ional tribological p.rformance when sliding against steel or cast iron in inert gas environments. Comp.red to exp.riments in humid air, about an order of magnitude lower wear rate and several times lower coefficient of friction have been rep.rted for tests conducted in dry.nitrogen and hy.rogen. Moreover, trace moisture has been shown to affect the friction and wear significantly.of this tribosy.tem, although a p.ssible effect of oxy.en cannot be ruled out due to uncertainties regarding the oxy.en concentrations. While several studies have p.inted out the environmental sensitivity.of CF/p.FE, the understanding of the underly.ng mechanisms are very.limited. The objective of this research is to investigate the individual and combined effect of oxy.en and moisture on the tribological behavior of CF/p.FE sliding against steel. Additionally. this study.aims to elucidate the underly.ng mechanisms that govern the environmental sensitivity.of the sy.tem. Climate-controlled three-p.n-on-disc exp.riments were conducted in nitrogen atmosp.eres at various concentrations of oxy.en and moisture. The tribological results clearly.demonstrate that both moisture and oxy.en contribute to increased friction and wear. However, the adverse effect was much more p.onounced for oxy.en than moisture. A qualitative method was develop.d to estimate the tribofilm coverage on the CF/p.FE surface. Results showed strong correlation between high coverage of strongly.adhered tribofilm and low wear rate. Moreover, a loosely.adhered tribofilm was observed on top.of the CF/p.FE surface in p.esence of moisture. FTIR analy.is indicated that the loosely.adhered tribofilm found in the moisture-enriched environment contained a significant amount of adsorbed water, which may.exp.ain the lower coefficient of friction in p.esence of moisture comp.red to oxy.en. The adsorbed water in the loosely.adhered tribofilm coul

Nonadiabatic Holonomic Quantum Comp.tation Based on Ry.berg Ground State Blockade

引用

Chinese p.y.ics Letters 2024年第4期41卷 25-31页

作者：苏石磊王琛宋佩瑶陈刚 School of p.y.ics Zhengzhou UniversityZhengzhou 450001China

Quantum gates are crucial for quantum comp.tation and quantum information p.ocessing. However, their effectiveness is often hindered by.sy.tematic errors and decoherence. Therefore, achieving resilient quantum gates to these factors is of great significance. We p.esent a method to construct nonadiabatic holonomic single-and two-qubit gates in a Ry.berg ground-state-blockade regime. Our ap.roach utilizes a far-off-resonant technique for the single-qubit gate and a modified Ry.berg antiblockade for the two-qubit gate. The reduction of the p.p.lation of single-and two-excitation Ry.berg states and the nonadiabatic holonomic p.ocess during the construction of the gates ensure robustness to decoherence and sy.tematic errors, resp.ctively. Numerical results demonstrate the fidelity.and robustness of our scheme. The p.op.sed scheme holds p.omise for future ap.lications in quantum comp.tation and quantum information p.ocessing tasks.
