Different Complexation of Nd3+ and Sm3+ with L-Malic Acid

Complexation of Nd³⁺ and Sm³⁺ ions with L-malic acid (H₃Mal) in aqueous solutions (I = 0.1 mol/l KCl) was studied by pH-metric titration at the molar concentration ratios of H₃Mal : lanthanide equal to 1 : 2, 1 : 1, 2 : 1 in the pH range 2.8–9.5. Mathematical modeling of composite equilibrium processes was used to determine the compositions and stability constants of Nd(III) and Sm(III) L-malate complexes. It was found that in addition to the 1 : 1 and 1 : 2 complexes with different degree of deprotonation, the protonated L-malate complexes and hydroxo complexes of these metals were also formed. The Sm³⁺ and Nd³⁺ ions were established to behave differently during complexation with H₃Mal.

真空中紫外辐射冲量与铝表面作用的模拟

为研究激光脉冲与真空中被照射的铝靶的耦合作用，进行了理论分析和数值计算，所给的结果是依据包括热传导、气化和等离子体燃烧在内的数学模型得到的。指出了对汽化过程的正确描述和重要性。同时发现双光子电离可导致初始电子数密度和其温度的增加。这一效应，从长远来看会导致激发态原子密度和电子产生速率的增加，但这是以降低光电离的产生为代价的。计算所得冲量耦合和等离子体阈值数据与实验结果吻合的较好。
