| 1 | Running-in friction of hip joint replacements can be significantly reduced:The effect of surface-textured acetabular cup显示文摘Hip joint replacements represent the most effective way of treatment for patients suffering from joint diseases.Despite the rapid improvement of implant materials over the last few decades,limited longevity associated with wear-related complications persists as the main drawback.Therefore,improved tribological perfor-mance is required in order to extend the service life of replacements.The effect of surface texturing of ultra-high molecular weight polyethylene(UHMWPE)acetabular cup was investigated in the present study.Unique tilling method was utilized for manufacturing the dimples with controlled diameter and depths on the contact surface of the cup.The experiments with four commercial femoral components and two model lubricants were realized.The main attention was paid to a coefficient of friction considering the differences between the original and the dimpled cups.Results showed remarkable lowering of friction,in general.Focusing on the simulated human synovial fluid,friction was reduced by 40%(alumina ceramic),38.8%(zirconia toughened ceramic),25.5%(metal),and 9.9%(oxinium).In addition,the dimples helped to keep the friction stable without fluctuations.To conclude,the paper brings a new insight into frictional behaviour of the hip replacements during running-in phase which is essential for overall implant lifespan.It is believed that proper surface texturing may rapidly improve the life quality of millions of patients and may lead to considerable financial savings. | David NECAS Hatsuhiko USAMI Tatsuya NIIMI Yoshinori SAWAE Ivan KRUPKA Martin HARTL | 2020 | Friction2020，8，6： | 2 |

| 10 | Calculated Lattice Energies of Energetic Materials in a Prediction of their Heats of Fusion and Sublimation显示文摘The paper specifies an unambiguous basic relationship between the published results of ab initio calculations of lattice energies, E L,and heats of sublimation, ΔH s,of individual energetic materials. In this relationship,the ΔH s value has been replaced by heats of fusion, ΔH m,tr . Thereby its unambiguity has been lost,and the similarity of details of molecular structure begins to be of decisive importance. The resulting partial relationships,together with the basic relationship,have been used for prediction of ΔH s,and ΔH m,tr values of technically attractive polynitro compounds. | Svatopluk Zeman, Miloslav Krupka (Department of Theory and Technology of Explosives,University of Pardubice CZ 532 10 Pardubice, Czech Republic) | 2002 | 含能材料2002，10，1： | 1 |
