Two-dimensional (2D) lamellar materials have unique molecular structures and mechanical properties, among which molybdenum disulfide (MoS2) graphitic carbon nitride (g-C3N4) with different interaction forces served as reinforcing phase for polytetrafluoroethylene (PTFE) composites in the present study. Thermal stability, tribological thermomechanical properties of were comprehensively investigated. It was demonstrated that g-C3N4 improved elastic deformation resistance thermal degradation...

Electrocatalytic conversion of biomass platform chemicals to jet fuel precursors is a promising approach alleviate the energy crisis caused by excessive exploitation and consumption non-renewable fossil fuels.

We propose to jointly explain the electron/muon $g-2$ anomalies in framework of anomaly mediated SUSY breaking (AMSB) scenario. Two Yukawa deflected AMSB models are proposed and discussed depth: one with lepton-specific interactions other messenger-matter interactions. Both found be able at $2 σ$ level by naturally realizing preferred parameter space $μM_1,μM_2&lt;0$ very heavy left-handed smuon.

Acidic promoters are significant in the hydrodeoxygenation (HDO) of bioderived furans into alkanes over metal-acid bifunctional catalysts. Here, a supported Pd/HPW-SiO2 catalyst was prepared to investigate promotion effect phosphotungstic acid (HPW) on HDO HMF-acetone adduct (H-Ac). Characterizations suggested that an intimate contact between Pd and HPW established Pd/HPW-SiO2. significantly reduced reduction temperature oxides with enhanced hydrogenation capability.

Abstract Polyimide composites have been extensively used as motion components under extreme conditions for their thermal stability and special self-lubricating performance. In the present study, Ag-Mo hybrids lubricant fillers were incorporated into thermosetting polyimide to prepare a new type of tribo-materials (TPI-1) at high temperature. Comprehensive investigations different temperatures reveal that newly developed TPI-1 exhibits better reduction in friction wear rate below 100 °C, but...

The minimal supersymmetric standard model (MSSM) with complex parameters can contribute sizably to muon/electron anomalous magnetic dipole momemnt ($g-2$) and electric moment (EDM). electron $g-2$ interplays EDM; the muon also interplay EDM assuming universality between smuon selectron masses, either of which constrain relevant CP-phases in MSSM. In this work, we first use such an derive approximate analytical upper limit on CP-phase. Then extensively scan parameter space obtain more...

Abstract In this article, thermosetting polyimide (TPI) composites based on two ideal ingredients (graphite/graphene‐like carbon nitride, g‐C 3 N 4 ) were designed with different fibers and their tribological performance was comprehensively investigated at high temperatures. It found that the synergistic effect between solid lubricants graphite blended reinforced friction wear performance. Extremely lower behavior of TPI composite is attained aramid pulps (APs) More importantly, an obvious...
