摘要：
A specialized ethylamine-bridged β-cyclodextrins (EB β-CD) was synthetized. EB β-CD’s adsorption properties of thorium ions were performed. Experimental results show that the adsorption of thorium using the EB β-CD can achieve equilibrium within 60 min at room temperature under the condition of pH 4, the adsorbance is 10.49 mg g−1. The results of SEM and BET nitrogen adsorption show that, EB β-CD is typical mesoporous material. According to pseudo-second-order kinetics, the adsorption of Th(IV) indicating the influence of textural properties of EB β-CD on the rate of adsorption. The thermodynamic parameters obtained showed that the adsorption process is exothermic, spontaneous process. © 2015, Akadémiai Kiadó, Budapest, Hungary.

摘要：
In this paper, a new core-shell composite of nordihydroguaiaretic acid (NDGA) molecularly imprinted polymers layer-coated silica gel (MIP@SiO<inf>2</inf>) was prepared through sol-gel technique and applied as a material for extraction of NDGA from Ephedra. It was synthesized using NDGA as the template molecule, γ-aminopropyltriethoxysilane (APTS) and methyltriethoxysilane (MTEOS) as the functional monomers, tetraethyl orthosilicate (TEOS) as the cross-linker and ethanol as the porogenic solvent in the surface of silica. The non-imprinted polymers layer-coated silica gel (NIP@SiO<inf>2</inf>) were prepared with the same procedure, but with the absence of template molecule. In addition, the optimum adsorption affinity occurred when the molar ratio of NDGA:APTS:MTEOS:TEOS was 1:6:2:80. The prepared MIP@SiO<inf>2</inf>and NIP@SiO<inf>2</inf>were analyzed by scanning electron microscopy (SEM), thermogravimetric analysis (TGA), and Fourier transform-infrared spectroscopy (FT-IR). Their affinity properties to NDGA were evaluated through dynamic adsorption, static adsorption, and selective recognition experiments, and the results showed the saturated adsorption capacity of MIP@SiO<inf>2</inf>could reach to 5.90 mg g<sup>-1</sup>, which was two times more than that of NIP@SiO<inf>2</inf>. High performance liquid chromatography (HPLC) was used to evaluate the extraction of NDGA from the medicinal plant ephedra by the above prepared materials, and the results indicated that the MIP@SiO<inf>2</inf>had potential application in separation of the natural active component NDGA from medicinal plants. ©2015 Elsevier B.V.

摘要：
文章利用Gaussian03程序,采用密度泛函理论（DFT）,结合B3LYP方法和组合基组水平上研究了噻吩分子在过渡金属Co或Mo的催化作用下裂解开环反应的机理。计算结果表明,反应物中硫原子首先与过渡金属原子结合而形成稳定的中间体,然后进行分子内裂解,而脱硫过程主要依赖了高活性Co-H或Mo-H基团的参与。反应途径的势能剖面分析得知,两种金属上噻吩的裂解脱硫有不同的通道,过渡金属Mo较Co更容易促进噻吩的开环裂解,需要克服的最大势垒仅为48.63 kJ/mol,最大活化能仅为40.93kJ/mol,共同的产物为丁二烯碳正离子基团。

摘要：
L-3-n-butylphthalide molecularly imprinted polymers (MIPs) were synthesized using l-3-n-butylphthalide as template molecule, acrylamide as functional monomer, ethylene glycol dimethacrylate as cross-linking agent, and acetone as the porogenic solvent through precipitation polymerization. The non-imprinted polymers (NIPs) were prepared with the same procedure, but with the absence of template molecule. The optimum preparation conditions of the MIPs such as the functional monomer, the porogenic solvent, the molar ratio of the template to the functional monomer and the molar ratio of the template to the cross-linker were investigated in detail. Prior to the polymerization, the molecular simulation with the computer-aided design was used to help choose a suitable polymerization porogen for the molecularly imprinted pre-assembled system and study the interactions between l-NBP and the functional monomers. The synthesized polymers were characterized with FTIR and SEM to observe their structures as well as the morphologies, and their adsorption properties were respectively evaluated by static and dynamic adsorption as well as selectivity experiments. Scatchard analyses revealed that there were high and low affinity sites formed in the MIPs, which elucidated good affinity to l-NBP in the ethanol system. The adsorption capacity of the MIPs for l-NBP was 3.561 mg g<sup>- 1</sup>, with an imprinting factor (α) of 2.321 when compared with that of the NIPs. Scatchard analysis illustrated that the binding sites with affinity for l-3-n-butylphthalide molecules were formed in the prepared MIPs. ©2015 Elsevier B.V. All rights reserved.

Abstract: How to realize high catalytic desulfurization of thiophene cracking of transition metals is the major problem of petroleum processing. On the basis of the existing experiment, we combine Gaussian03 progress with the density functional theory (DFT) and B3LYP method to study the thiophene molecular adsorb microscopic behavior on the four kinds of transition metal as M = (Co,Ni,Cu,Zn) on Genecp basis set level. Calculation results show that: different transition metal atoms of thiophene molecular adsorption, adsorption exists different; transition metal Co and Cu adsorption is given priority to with alpha, the energy of which after the adsorption decreased 479.621 and 369.203 kJ/mol respectively; transition metal Ni adsorption is given priority to with beta, the energy of which after the adsorption decreased as high as 671.241 kJ/mol; transition metal zinc adsorption to the delta is given priority to, the energy of which after the adsorption decreased after 165.094 kJ/mol; There is another adsorb behavior as θ position exists about thiophene molecule on the transition metal Cu and Zn. The calculation of adsorption energy should consider the zero-point energy correction.#@#@#摘要: 如何实现过渡金属高效催化噻吩裂解脱硫是石油加工环节的重大难题。在已有的实验基础上，我们利用Gaussian03程序，采用密度泛函理论(DFT)，使用B3LYP方法在Genecp基组水平上研究了噻吩分子与四种过渡金属M = (Co, Ni, Cu, Zn)的吸附微观行为。计算结果表明：不同的过渡金属原子对噻吩分子的吸附存在着不同的吸附位，过渡金属Co与Cu吸附以α位为主，吸附后能量分别降低了479.621 kJ/mol和369.203 kJ/mol；过渡金属Ni吸附以β位为主，吸附后能量降低了高达671.241 kJ/mol；过渡金属Zn吸附以δ位为主，吸附后能量降低了165.094 kJ/mol，过渡金属Cu与Zn原子吸附噻吩分子还存在有θ位的吸附。吸附能量的计算应考虑零点能的校正。

摘要：
A novel and highly sensitive electrochemical DNAzymes biosensor was fabricated using Au nanoparticles (AuNPs) immobilized on the surface of Au electrode that had been previously modified with self-assembled monolayers of 1,6-hexanedithiol. Different modified electrodes were prepared and characterized by cyclic voltammetry and electrochemical impedance spectroscopy. The AuNPs were found to have a large surface area to anchor a large number of negatively charged phosphate backbones of DNAzymes, which further absorbed the electroactive indicator of hexaammineruthenium(III) ([Ru(NH 3 ) 6 ] 3+ ) to amplify the electrochemical signal. In the presence of target molecules, a large amount of DNA partly associated with [Ru(NH 3 ) 6 ] 3+ were removed from the electrode surface, leading to a significant decrease in peak current. Differential pulse voltammetry signals of [Ru(NH 3 ) 6 ] 3+ provided quantitative measures of the concentrations of uranyl ion (UO 2 2+ ), with linear calibration ranging from 13 pM to 0.15 nM and a detection limit of 5 pM. The presence of other metal ions did not affect the detection of UO 2 2+ , which indicated the high specificity of UO 2 2+ . Therefore, a new electrochemical DNAzymes sensor was designed with specific DNAzymes and AuNPs as immobilization platform and signal amplifier. © 2014 Akadémiai Kiadó, Budapest, Hungary.

摘要：
The geometric structure optimization, frequency analysis, infrared spectroscopy, natural charge population, the natural bond orbital (NBO) analysis, the molecular and the frontier orbital energy are calculated about glucose, pyran-fructose, furfuran-fructose and inulin molecule by using density functional theory (DFT) method in B3LYP on the 6-311+g(d,p) basis set level. It is shown the stability order is: furfuran-fructose > pyran-fructose > glucose > inulin. We find that inulin's chemical potential is maximum, the chemical hardness is minimum and the electrophilicity index is maximum using the concept DFT method, which could account for it's pharmacological activity. The Fukui function scanning has shown the C2 atom in inulin molecule has strong electron-losing ability and it is the active center in the molecule. The EBDE calculation has shown the position of O2--H is the most easily broken off and the bond energy is only 94.65 kcal mol-1, which is far less than the adiabatic ionization potential value, all of that could be a reasonable theoretical interpretation for the pharmacological activity of inulin. © 2014, Chemical Publishing Co.

摘要：
采用密度泛函（DFT）中B3LYP方法,在6-311 ＋G（d,p）基组水平上对葡萄糖、吡喃型果糖、呋喃型果糖、D-万寿菊糖进行了几何构型优化、频率分析、红外光谱、自然电荷布居、NBO分析、分子能量及前线轨道能级计算,推导出分子的稳定性顺序为：呋喃型果糖＞吡喃型果糖＞葡萄糖＞菊糖.引入概念DFT活性指数分析表明菊糖分子的化学势μ数值大、化学硬度η小、亲电指数ω大,表明了它具有特殊的活性.Fukui指数扫描表明菊糖分子中C2原子具有较大的给电子能力,是整个分子的活性中心.抗氧化能力的EBDE数值计算表明2-H最容易断裂,其数值是为94.65 kcal· mol-1,远小于它的绝热电离势,这可为解释菊糖分子的抗氧化活性做合理的理论指导.

摘要：
在传统的制药工程专业实验培养体系的研究基础上,我们提出了新的自选型专业实验培养体系,通过实践表明:新的自选型专业实验培养体系有利于提高本科学生的专业兴趣和积极性,又有利于实验资源的整合与节约,符合新时代高等教育教学改革的发展需要,对实验教学改革具有重要的促进作用.
