In this study, new nano spherical graphene modified with LDH(Layered Double Hydroxide) was prepared and used to remove As(Ⅲ) ion from aqueous solutions. At first, graphene oxide was synthesized from graphite using a well-known Hammer method. The obtained graphene oxide solution was sprayed in octanol solution under different temperatures and sprayed speed as influenced variables. The structure and physical characterization of synthesized spherical graphene oxide were determined by various techniques,including FT-IR, N_(2) adsorption–desorption, SEM, TEM, and EDX. In the next step, the hydrothermal method was applied to deposition LDH on the spherical graphene oxide. The synthesized spherical graphene modified by LDH was used to remove As(Ⅲ) as a toxic heavy metal ion. The effect of influenced variables including p H, contact time, amount of sorbent, and type eluent studied and the optimum values were as 8, 30, 50, and HCl(0.5 mol·L^(-1)), respectively. After optimization, the studied sorbent was shown a high adsorption capacity(149.3 mg·g^(-1)). The adsorption mechanism and kinetic models exhibited good agreement with the Langmuir isotherm and pseudo-second-order trends, respectively. besides, the synthesized product was tested for seven times without significant loss in its sorption efficiency.

Fusobacterium nucleatum is an anaerobic, commensal, gram-negative oral bacterium that is carcinogenic and causes a wide range of human diseases. The present study focused on the analysis of the hypothetical protein, HMPREF3221_01179, derived from F. nucleatum strain MJR7757b, employing various computational methods to anticipate both its structure and functional characteristics. NCbI conserved domain analysis, NCbI bLASTp and MEGA Phylogenetic tree study characterize the target protein as an outer membrane efflux protein (ToIC family) which facilitate the bacterial transmembrane transport. With a molecular weight of 52120.02 Da, an isoelectric point (pI) of 8.33, and an instability index of 29.47, the protein is anticipated to exhibit good solubility in the extracellular space and crucial stability for pharmaceutical applications. The protein’s structure meets quality standards during the construction and refinement of its 3D model. The efflux inhibitor Arginine beta-naphthylamide exhibits a significant binding affinity (-7.1 kcal/mol) to the binding site of the target protein. The in-silico analysis improves the understanding of the protein and facilitates future investigations into therapeutic medication.

目的通过对电控差速锁壳体热锻工艺方案进行优化，解决其形状复杂而导致的填充不满、折叠等锻造缺陷问题。方法依据壳体的结构特征，设计了三种闭式热模锻工艺方案。建立了壳体热锻过程热力耦合有限元模型及模具应力分析数值模型。利用该模型对三种模锻工艺方案进行模拟，通过对模拟结果的对比分析，获得优化工艺方案。结果通过对三种工艺方案进行模拟分析，发现在镦粗方案和缩颈方案下金属能够完整填充终锻模具型腔，而小孔方案在终锻中出现了空穴-回填现象，可能导致折叠的产生，因此仅对镦粗方案和缩颈方案做进一步对比。通过两种方案在成形载荷、锻件温度/应变、模具应力以及坯料体积等方面的对比研究，发现与缩颈方案相比，镦粗方案的坯料体积略大，但锻件温度范围和分布更合理，制坯和终锻工序的锻件应变较小，制坯和预锻工序的最大模具应力更小。结论通过综合对比分析，确定镦粗方案为优化方案。采用壳体热锻实验，从锻件外形、微观组织和硬度等方面验证了该优化方案的有效性。

利用光催化的方法将太阳能转化为氢能,是生产可持续燃料的有效途径之一.金属有机框架(MOFs)作为一类新兴的有机-无机杂化材料引起了研究者的广泛关注.由于MOFs材料的结构可调性,在框架中引入具有良好光吸收性能的基元,可以使MOFs在分子尺度有序排列的同时实现光催化析氢.单组分MOFs由于结构的相对有限性,存在电荷分离效率低的问题,而供体-受体(D-A)型双组分MOFs能够有效地促进电荷转移,同时电荷转移相互作用可以扩大光谱吸收范围,这些优良性能使之成为极具潜力的光催化剂.因此,寻找能够形成D-A结构的MOFs材料,实现高效光催化析氢仍然是一项亟需解决的科学问题.本文采用简单的溶剂热法将供体卟啉与受体二苯并噻吩砜(bTDO)相结合,构筑了一种卟啉基(TCPP)的D-A型MOF(TCPP-Zn-bTDO),其中, TCPP供体分子和bTDO受体分子通过Zn2+离子配位连接.红外吸收光谱中砜基的特征吸收峰以及电感耦合等离子体质谱表明有硫元素存在,说明成功引入了电子受体***-Zn-bTDO的光催化析氢效率较好,为1.48 mmolg-1h-1,是单组分MOF(TCPP-Zn)的3.14倍.此外, TCPP-Zn-bTDO具有较好的光催化稳定性,连续40 h实验后,光催化活性没有显著降低.紫外可见吸收光谱和光电流测试结果表明, TCPP-Zn-bTDO具有更高的光吸收效率和更强的光电流响应,说明TCPP-Zn-bTDO可以产生更多的光生载流子,从而有利于光催化析氢反应.同时, bTDO的加入增大了分子偶极子,有效增强了内建电场.表面电荷密度以及开路电压等表明, TCPP-Zn-bTDO的内建电场强度是单组分MOF的1.44倍.通过莫特肖特基曲线与禁带宽度计算出TCPP-Zn-bTDO具有更负的导带位置,因而具有较强的热力学驱动力和电子还原能力,从而促进光催化析氢.综上,本文设计了一种简单的方法来构筑高活性的D-A型MOF, D与A之间的电荷转移相互作用能有效促进光生载流子分离,为光催化析氢材料的设计提供参考.

Optical features of a semiconductor–dielectric photonic crystal are studied theoretically. Alternating layers of micrometer sized SiO2/In Sb slabs are considered as building blocks of the proposed ideal crystal. by inserting additional layers and disrupting the regularity, two more defective crystals are also proposed. Photonic band structure of the ideal crystal and its dependence on the structural parameters are explored at the first step. Transmittance of the defective crystals and its changes with the thicknesses of the layers are studied. After extracting the optimum values for the thicknesses of the unit cells of the crystals, the optical response of the proposed structures at different temperatures and incident angles are investigated. Changes of the defect layers’ induced mode(s) are discussed by taking into consideration of the temperature dependence of the In Sb layer permittivity. The results clearly reflect the high potential of the proposed crystals to be used at high temperature terahertz technology as a promising alternative to their electronic counterparts.
