Redox modulated hydrogelation of a self-assembling short peptide amphiphile

Hydrogels resulting from the self-assembly of small peptides are smart nanobiomaterials as their nanostructuring can be readily tuned by environmental stimuli such as pH,ionic strength and temperature,thereby favoring their practical applications.This work reports experimental observations of formation of peptide hydrogels in response to the redox environment.Ac-I 3 K-NH 2 is a short peptide amphiphile that readily self-assembles into long nanofibers and its gel formation occurs at concentrations of about 10 mmol/L.Introduction of a Cys residue into the hydrophilic region leads to a new molecule,Ac-I 3 CGK-NH 2,that enables the formation of disulfide bonds between self-assembled nanofibers,thus favoring cross-linking and promoting hydrogel formation.Under oxidative environment,Ac-I 3 CGK-NH 2 formed hydrogels at much lower concentrations(even at 0.5 mmol/L).Furthermore,the strength of the hydrogels could be easily tuned by switching between oxidative and reductive conditions and time.However,AFM,TEM,and CD measurements revealed little morphological and structural changes at molecular and nano dimensions,showing no apparent influence arising from the disulfide bond formation.     

个体主义集体主义文化价值理论的细化和发展——以广告研究为例

个体主义集体主义二元文化价值理论已经发展成为垂直性和平行性的个体主义和集体主义的四维体系。本文梳理了该理论的发展,并以广告研究为例,在新的理论框架下,讨论如何预测多种消费行为和消费满意。研究结果表明垂直性和平行性的细分有助于更好地理解个体主义/集体主义理论解释下的已知现象。虽然在起动方法上存在挑战,以等级和地位为动机的文化模式研究在未来势必会成为新的研究热点,丰富跨文化理论的研究内容。

Synthesis process of Ba-ferrites from α-FeOOH and γ-FeOOH and investigation of magnetic properties

The claviform BaFe₁₂O₁₉ crystals were synthesized by the precipitation-toptactic reaction method using α-FeOOH and γ-FeOOH as raw materials respectively. The synthesis processes of BaFe₁₂O₁₉, studied by XRD, SEM, EDS, FT-IR, and TG-DTA techniques, included preparations of precursor γ and precursor α, formations of α-Fe₂O₃ and BaFe₂O₄, and production of rod-like BaFe₁₂O₁₉ through dehydroxylation of pod-like FeOOH, followed by reactions of α-Fe₂O₃ with BaCO₃ and BaFe₂O₄. The crystallinity of α-Fe₂O₃ and BaCO₃ from precursor α was better than from precursor γ due to the direct dehydroxylation of α-FeOOH, resulting in a lower nucleation rate and better crystallinity of BaFe₂O₄. BaFe₁₂O₁₉ prepared from precursor α showed lower crystallinity and purity with a higher length-diameter ratio than from precursor γ. The VSM results proved that the appearance of final products had an important influence on magnetic properties.

随机粗糙面电磁散射特性的研究方法

随机粗糙表面电磁散射理论在光学、声学、电磁学、医学等领域有着广泛的应用.由Maxwell方程结合边界条件导出的积分方程是粗糙面电磁散射问题的基本理论依据.本文将研究粗糙面电磁散射的方法分为两类-近似法与数值法.近似法主要有基尔霍夫近似与微扰法;数值法主要有矩量法与时域有限差分方法等.近似法简单,但有一定的适用范围;数值法较精确,但其计算复杂.实际中往往采用近似法计算粗糙面的电磁散射,而用数值法来研究近似法的有效性.
