解读历史小说的大众化审美取向

历史小说受到了读者的青睐，受到了世人的关注，历史小说的大众审美取向是小说受到关注的关键因素。如何正确看待历史小说的大众审美取向，如何把握大众审美取向的度，便是进行历史小说创作的作家们应该深思的．     

INVESTIGATION OF STRUCTURE AND PROPERTIES FOR POLYMER SYSTEMS BASED ON DYNAMIC RHEOLOGICAL APPROACHES

The dynamic theological measurements have been a preferred approach to the characterization of the structure and properties for multi-component or multi-phase polymer systems, due to its sensitive response to changes of structure for these heterogeneous polymers. In the present article, recent progresses in the studies on dynamic theology for heterogeneous polymer systems including polymeric composites filled with inorganic particles, thermo-oxidized polyolefins, phaseseparated polymeric blends and functional polymers with the scaling and percolation behavior are reviewed, mainly depending on the results by the authors‘ group. By means of theological measurements, not only some new fingerprints responsible for the evolution of morphology and structure concerning these polymer systems are obtained, the corresponding results are also significant for the design and preparation of novel polymer-based composites and functional materials.     

Synthesis of novel aza analogues of 2-substituted-2,3-dihydro-1,4-benzodioxins as potential new scaffolds for drug discovery

New synthesis approaches that have led to a series of novel aza analogues of the 2-substituted-2,3-dihydro-1,4-benzodioxin core, bearing versatile bromomethyl group on the non aromatic oxygenated ring, are described. According to their structures these novel scaffolds can be useful intermediates for the preparation of potential new therapeutic agents.

Synthesis of iron‐based metal organic framework and its visible light‐driven photocatalytic degradation of dye pollutants

A novel metal–organic compound [Fe (ox)(phen)]_n (phen = 1,10‐Phennannthroline, ox = oxalate acid) has been hydrothermally synthesized and structurally characterized by X‐ray single‐crystal diffraction, X‐ray diffraction, IR, UV–vis diffuse reflectance spectroscopy and X‐ray photoelectron spectroscopy. The compound crystallized in monoclinic,space group P2₁ with a = 0.92289 (3) nm, b = 1.35719 (3) nm, c = 1.02012 (4) nm,β = 94.372 (2)°,V = 1.27402(8)nm³,Z = 2,and exhibited a 2D layer structure. The photocatalytic activities of the compound were evaluated by decomposing Rhodamine B (RhB) and methyl orange (MO) under the visible light irradiation. In addition, the mechanism of the photocatalytic properties were proposed during this process.     

Synthesis and characterization of MgO nanoparticles supported on ionic liquid‐based periodic mesoporous organosilica (MgO@PMO‐IL) as a highly efficient and reusable nanocatalyst for the synthesis of novel spirooxindole‐furan derivatives

The synthesis and catalytic application of a novel MgO containing periodic mesoporous organosilica with ionic liquid framework (MgO@PMO‐IL) is described. The prepared MgO@PMO‐IL was characterized by Fourier transform‐infrared spectroscopy, N₂ adsorption/desorption, transmission electron microscopy, field emission‐scanning electron microscopy, thermogravimetric and inductively coupled plasma analyses. This nanocatalyst was successfully applied as a highly efficient and recoverable catalyst for the synthesis of novel spirooxindole‐furan derivatives via the three‐component reaction of 1,3‐dicarbonyl compounds, N‐phenacyl pyridinium salts and isatin derivatives. The products were achieved in high to excellent yields with a simple work‐up procedure and short reaction times, and the catalyst could be recovered through a simple filtration process and successfully reused seven times without any significant decrease in its efficiency.     

《歧路灯》的文类归属及家训主题解读

长期以来,学界多将《歧路灯》视为世情小说、教育小说或家庭小说。然而其对程朱理学的推崇、明显的训诫教化特征和略显疏散的叙事风格,始终与上述定位不甚匹配,影响其在文学史上的价值认定和评价。鉴于明清时期家训撰写的普遍性,结合李绿园的社会身份及写作意图,依据《颜氏家训》等确立的家训文学类属标准,将《歧路灯》视为"家训小说",更利于其主题阐释和价值评估。     

论《水浒传》作者思想的矛盾性

忠君观念与绿林化精神的冲突是作痛苦和悲剧心理产生的根源，同时也是作并不一味颂扬这些英雄行为的原因。作强烈的忠君观念指引着梁山英雄接受招安，但他又清楚招安的结果势必带来英雄的覆灭。宋、方挥戈，实为同类相残。鹬蚌相争，将同归于尽。忠义本应两全，但义不得已而毁灭。所热爱的英雄必须毁灭，使他产生浓烈的悲剧意识。这些矛盾长期撕扯着灵魂，使他产生近似于自虐的心理倾向，产生一种刺痛自己的需要和满足。《水浒传》这一悲剧的创作使作获得了刺疼自己的快感。作在作品中表达的他对传统思想某些领域的思考，使他成为明代反传统思潮发轫前，对传统思想产生重大疑问的思想。

定量研究环糊精聚合物包合作用的新方法

通过聚合物接枝改性的方法制备了β-环糊精改性聚丙烯酸(PAAβCDen)和丹磺酰基团改性聚丙烯酸(PAADSen),并用二维氢核磁、流变学、紫外-可见分光光度法等方法对接枝于聚合物上的环糊精主客体相互作用进行了定量研究。结果表明:接枝于聚丙烯酸链上的β-环糊精和丹磺酰基团之间能够形成主客体包合结构,从而使PAAβCDen和PAADSen之间产生交联,并且首次采用紫外-可见分光光度法测得接枝于不同聚合物链上环糊精基团和丹磺酰基团之间的结合常数为(27.5±3)L/mol,远小于自由状态下β-环糊精与丹酰胺之间的结合常数((103±5)L/mol)。
