A series of thiophenyl-containing 3-thiophene derivatives （4a--4i） were prepared via the reaction of chalcone-analogua compounds （3a--3i） and thiophenol in the presence of catalytic amount of KOBu-t in CH2C12 with moderate to high yields. The mechanistic pathway of the reaction was explained by the Michael-type addition of thiophenol to chalcone derivatives （3a--3i）.

作者： yakup Yιldιrιm Emrullah Yasar Department of Mathematics Faculty of Arts and Sciences Uludag University

We applied the multiple exp-function scheme to the（2＋1）-dimensional Sawada-Kotera（SK） equation and（3＋1）-dimensional nonlinear evolution equation and analytic particular solutions have been deduced. The analytic particular solutions contain one-soliton, two-soliton, and three-soliton type solutions. With the assistance of Maple, we demonstrated the efficiency and advantages of the procedure that generalizes Hirota＇s perturbation scheme. The obtained solutions can be used as a benchmark for numerical solutions and describe the physical phenomena behind the model.

The sputtering process of Ar＋Ni（100） collision systems is investigated by means of constant energy molecular dynamics simulations. The Ni（100） slab is mimicked by an embedded-atom potential, and the interaction between the projectile and the surface is modelled by using the reparametrized ZBL potential. Ni atom emission from the lattice is analysed over the range of 20-50 eV collision energy. Sputtering yield, angular and energy distributions of the scattered Ar and of the sputtered Ni atoms are calculated, and compared to the available theoretical and experimental data.

Linear thermal expansion coefficient （TEC） of Ti bulk is investigated by means of molecular dynamics simulation. The elastic minimum image convention of periodic boundary conditions is introduced to allow the bulk to adjust its size according to the new fixed temperature. The TEC and the specific heat of Ti are compared to the available theoretical and experimental data.

以胡桃壳在450℃裂解得到生物质炭BC450,以胡桃壳与20%沥青砂在450℃裂解得到BCTS20,与商业活性炭(CAC)进行对比研究去除污水中Cr(Ⅵ)的能力。与BC450相比,BCTS20具有更丰富的表面官能团。在适当条件下,BC450、BCTS20、CAC对Cr(Ⅵ)的去除率分别为80.47%、90.01%、95.69%。采用Langmuir、Freundlich、D-R模型研究吸附等温线,其中Langmuir模型最佳。BC450、BCTS20、CAC的最大Langmuir吸附容量分别为36.55、49.76、51.94 mg/g。这些炭材料对Cr(Ⅵ)的吸附可能归因于由离子交换、静电作用与螯合作用引起的化学过程。
