Abstract :
Viologen is capable of generating radicals in response to an applied stimulus, giving it an abundance of stimuli responsive properties. However, the radical state of viologen is often unstable, which hinders further studies on the radical properties of viologen. In this paper, the salicylhydrazide group was chosen as a donor group to bond with mono-substituted bipyridyl groups to obtain three novel D-A type viologen compounds. The compounds were harvested and characterized by X-ray single crystal diffraction, optical spectroscopy, EPR and DFT calculation, etc. The results show that compounds 1-3 adopt certain free radical states at room temperature under ambient light, which may be attributed to the electron-donating properties of the salicylhydrazide group and the degree of system conjugation. In addition, compound 1 has a hydrochromic property and compounds 2 and 3 have photocurrent effects under UV radiation. Three novel hydrazide viologen compounds were synthesized and studied by X-ray single crystal diffraction, and their stable free radical properties, hydrochromic properties and photocurrent effects were studied.

Abstract :
本文针对现有物理化学实验教材中的“乙酸乙酯皂化反应速率常数的测定”实验进行改进和拓展。首先,以夹套烧杯为皂化反应池,通过恒温水循环及磁力搅拌确保了实验过程中溶液浓度均匀、温度恒定;其次,取一定体积浓度为0.01 mol·L~(-1)的氢氧化钠溶液于反应池中待恒温后测定电导率值,记为κ_0,再使用微量取样器取等摩尔数的乙酸乙酯加入到反应器中并同时计时,测定不同时间的电导率值,记为κ_t;第三,通过数据归一化处理消除了电极常数的影响,使物理量意义明确、实验现象直观。改进后的实验步骤减少、数据测量准确性提高,可以测量高温条件下、快速的皂化反应速率常数,在有限的课时内学生可以通过分工协作、共享数据,获得表观活化能及指前因子。

Abstract :
The 6p orbit coupling of bismuth ions and the magnetism of iron ions endow bismuth-iron compounds with magnetic, optical and electrical properties. In this paper, non-rare-earth bismuth-iron crystals, KBa8Fe12(Bi6-xFex)O-38 (x = 0.2, 1.1, 2.0, 2.9, and 3.8), with a large magnetocaloric effect were prepared by a hydrothermal method. The structure-function relationship is discussed. With the increase of the Fe content, the lattice parameters and unit cell volume decrease, while the magnetization intensity shows an increase on the whole and a fluctuation at the same time. The increase of the Fe content can improve the magnetocaloric effect. Importantly, the maximum magnetic entropy change (Delta S-M) of KBa8Fe12(Bi4.9Fe1.1)O-38 is as high as 1.54 J kg(-1) K-1 at the low temperature of 2 K.

Abstract :
The skins of frogs of the family Ranidae are particularly rich sources of biologically active peptides, among which antimicrobial peptides (AMPs) constitute the major portion. Some of these have attracted the interest of researchers because they possess both antimicrobial and anticancer activities. In this study, with 'shotgun' cloning and MS/MS fragmentation, three AMPs, homologues of family brevinin-1 (brevinin-1HL), and temporin (temporin-HLa and temporin-HLb), were discovered from the skin secretion of the broad-folded frog, Hylarana latouchii. They exhibited various degrees of antimicrobial and antibiofilm activities against test microorganisms and hemolysis on horse erythrocytes. It was found that they could induce bacteria death through disrupting cell membranes and binding to bacterial DNA. In addition, they also showed different potencies towards human cancer cell lines. The secondary structure and physicochemical properties of each peptide were investigated to preliminarily reveal their structure-activity relationships. Circular dichroism spectrometry showed that they all adopted a canonical a-helical conformation in membrane-mimetic solvents. Notably, the prepropeptide of brevinin-1HL from H. latouchii was highly identical to that of brevinin-1GHd from Hylarana guentheri, indicating a close relationship between these two species. Accordingly, this study provides candidates for the design of novel anti-infective and antineoplastic agents to fight multidrug-resistant bacteria and malignant tumors and also offers additional clues for the taxonomy of ranid frogs.

Abstract :
Chiral compounds are known to be important not only because they are the fundamental components of living organisms, but also for their unique chiroptical properties. In recent years, scientists have fabricated several chiral organic supramolecular aggregates by using chiral physical fields, such as vortex flow. Herein, the relationship between dynamic chiroptical properties and rheological nature is discussed, suggesting the shear thinning properties of non-Newtonian fluids might help colloidal particles adopt a chiral arrangement in vortices. Furthermore, the storage modulus of colloids could be increased by adding a linking agent, which successfully kept the dynamic chiroptical properties in the static state. Moreover, the salt effect on the host-guest interaction involved in the colloids was studied, the results suggested a significant enhancement of the transferred dynamic circular dichroism for the achiral guest molecule.

Abstract :
Recently, scientists have reported a range of chiral fluorescence materials or chiral composites that can emit circularly polarized luminescence. Herein, two achiral metal-organic colloidal solutions were studied, showing active circularly polarized luminescence, which is observed in vortex stirring. The absolute values for g(lum) are 0.05 and 0.03 and the plus or minus sign of g(lum) depends on the colloidal structure and stirring direction, which make the property easy to manipulate. Further, the host-guest interaction study suggests both electrostatic interactions and coordination bonding may influence the chiroptical property from the colloidal solution to the guest molecule. Rhodamine 6G and its carboxylic acid derivative exhibit good quantum yields and acceptable g(lum) values in the colloidal solution.

通过改装二元气液平衡系统相图绘制实验的装置,同时测定了环己烷-乙醇气液系统建立平衡时的沸点和露点温度,绘制并对比未保温、保温和温度补偿条件下的环己烷-乙醇气液相图.研究发现,由于分馏效应的存在,未保温和简易保温情况下,测得的溶液的沸点与露点两者温度均存在较大的差异,利用沸点温度绘制的气相线存在严重失真;对系统进行了温度补偿后根据沸点和露点温度绘制的两条气相线能吻合较好,即气相分馏效应得到了解决.
