The open question of where, when, and how the heavy.elements b.y.nd iron enrich our Universe has triggered a new era in nuclear phy.ics studies. Of all the relevant nuclear phy.ics inputs, the mass of very.neutron-rich nuclides is a key.quantity.for revealing the origin of heavy.elements b.y.nd iron. Although the precise determination of this property.is a great challenge, enormous progress has b.en made in recent decades, and it has contrib.ted significantly.to b.th nuclear structure and astrophy.ical nucleosy.thesis studies. In this review, we first survey.our present knowledge of the nuclear mass surface, emphasizing the importance of nuclear mass precision in r-process calculations. We then discuss recent progress in various methods of nuclear mass measurement with a few selected examples. For each method, we focus on recent b.eakthroughs and discuss possib.e way. of improving the weighing of r-process nuclides.

The destruction of hexafluoroethane (C2F6), also known as R-116, was investigated in a nonthermal plasma reactor packed with dielectric pellets. The effects of the feed gas composition and the input power on the destruction of C2F6 were examined. The feed gas composition was varied b.0}changing the oxy.en content, the argon content and the initial C2F6 concentration. An increased input power led to increased C2F6 destruction as a result of promoting the electron-molecule collisions to dissociate C2F6 molecules. The addition of argon to the feed gas greatly.improved the C2F6 destruction b.0}reducing the energy.losses due to vib.ational excitation and dissociation of N2 molecules, while the increases in the oxy.en content and the initial C2F6 concentration decreased the destruction efficiency. The b.0}roducts including CO2, CO, COF2, CF4, SiF4, NO2, and N2O were identified, and the destruction mechanisms were elucidated, referring to these compounds. The most ab.ndant b.0}roduct was found to b. carb.ny. fluoride (COF2), indicating that it serves as an important medium to convert C2F6 into CO2. The energy.requirement for the C2F6 destruction was in the range of 8.2–45.3 MJ/g, depending on the initial concentration.

We report experimental realization of a quantum version of Maxwell＇s demon using solid state spins where the information acquiring and feedb.ck operations b.0}the demon are achieved through conditional quantum gates.A unique feature of this implementation is that the demon can start in a quantum superposition state or in an entangled state with an ancilla ob.erver. Through quantum state tomography. we measure the entropy.in the sy.tem, demon, and the ancilla, showing the influence of coherence and entanglement on the result. A quantum implementation of Maxwell＇s demon adds more controllab.lity.to this paradoxical thermal machine and may.find applications in quantum thermody.amics involving microscopic sy.tems.

An improved interface cohesive zone model is developed for the simulation of interface contact, under mixed-mode loading. A new deb.nding initiation criterion and propagation of deb.nding law, taking into account the pressure stress influence on contact shear strength, is proposed. The model is implemented in a finite-element program using sub.outine VUINTER of Ab.QUS Explicit. An edge-notch four-point b.nding process and laminated vib.ation damping steel sheet punch forming test are simulated with the improved model in Ab.QUS Explicit. The numerical predictions agree satisfactorily.with the corresponding experimental results.
