We note that while NNRF enables longer integration timesteps as compared to ReaxFF, energy and force calculations take, approximately, a factor of four times longer; scaling with system size and parallel performance are similar between ReaxFF and NNRF. The crystal structure and the equilibrium ...
张曦 等[53]利用 CyMe4-BTBP 作为萃取剂将其灌装到 SiO2 内制备得到 CyMe4-BTBP/SiO2,该萃取剂与 BTP 类 萃取剂相比 ,其耐酸性和耐辐照性更好.CyMe4- BTBP 在 0.1~4 mol∙L−1 HNO3 浓度下的负载量小于 9.1%,但吸附材料对 Am(III)和 Eu(III)的分离因子 (Separation Factor,SF)均在 100 ...
新型n-吡唑咔唑类化合物合成-工业催化专业论文.docx,4-硝基吡唑,通过单因素实验,得到较佳工艺条件:1-硝基吡唑5.7g,浓硫酸5mL,反应温度0℃,反应3h。在此条件下平均收率可达74.5%。最后,以4-硝基吡唑和9-(3-溴丙基)-9H-咔唑为原料合成9-(3-(4-硝基吡唑-1-基)丙基)-9H-
The generation of nitrous acid (HNO2) by ultrasound was investigated for an organic solution consisting of tri-n-butylphosphate, nitric acid (HNO3) and water under several conditions. The amount of HNO2 was found to increase by a factor of 40 upon ultrasound irradiation, and the concentration...
