Limb reduction in Squamata present the dramatic characteristic to focus and usually accompanied with particularly morphological modifications, impacting tremendous locomotion changing and might generate different energy requirement. Herein, we combined both morphological and mitochondrial genomic data to explore the evolution of phenotypic transformation and mitochondrial genome of limbless and body-elongated squamates. We collected phenotypic measurements of 503 individuals, representing limbed or limbless taxa across all major lineages in Squama ta to investiga te the morphological correla tions with limb-reduction. Furthermore, we provided the mitochondrial genome of the representative limbless and elongated species Dibamus bourreti(Angel, 1935) to detect selective constraints on limbless clades with published mitogenomes of other squa ma te reptiles. Our results evidenced tha t body elongation had certain negative relationship with limbreduction in Squamata lineage and Lacertilia lineage(R = –0.495, P < 2.2 e-16;R= –0.332, P = 1.1 e-13, respectively), while tail length showed slight correlation in both clades(R = 0.156, P = 4.3 e-04;R= 0.192, P = 2.1 e-05, respectively). Besides, detection demonstrated that ATP6 has experienced accelerated evolution among limbless lineages, suggesting selective pressure on mitogenomes may play an essential role in energy disparity for locomotion of limbed and limbless squamates.

Halogen bonding interactions between several halogenated ion pairs and CO2 molecules have been investigated by means of density functional theory calculations. To account for the influence of solvent environment, the implicit polarized continuum model was also employed. The bromide and iodide cations of ionic liquids (ILs) under study can interact with CO2 molecules via X O interactions, which become much stronger in strength than those in the complexes of iodo-perfluorobenzenes, very effective halogen bond donors, with CO2 molecules. Such interactions, albeit somewhat weaker in strength, are also observed between halogenated ion pairs and CO2 molecules. Thus, the solubility of CO2 may be improved when using halogenated ILs, as a result of the formation of X O halogen bonds. Under solvent effects, the strength of the interactions tends to be weakened to some degree, with a concomitant elongation of intermolecular distances. The results presented here would be very useful in the design and synthesis of novel and potent ILs for CO2 physical absorption.

The vapor-liquid equilibrium data of four binary systems (acetic acid +p-xylene, methyl acetate +n-propyl acetate, n-propyl acetate +p-xylene and methyl acetate +p-xylene) are measured at 101.33 kPa with Ellis equilibrium still, and then both the NRTL and UNIQUAC models are used in combination with the HOC model for correlating and estimating the vapor-liquid equilibrium of these four binary systems. The estimated binary VLE results using correlated parameters agree well with the measured data except the methyl acetate +p-xylene system which easily causes bumping and liquid rushing out of the sampling tap due to their dramatically different boiling points. The correlation results by NRTL and UNIQUAC models have little difference on the average absolute deviations of temperature and composition of vapor phase, and the results by NRTL model are slightly better than those by UNIQUAC model except for the methyl acetate +n-propyl acetate system, for which the latter gives more accurate correlations.

非常规离子是指伴随离子液体(ILs)不断创制而出现的离子,其最大特点是具有可设计性.当ILs处于无限稀释状态时,最为重要的传递性质是单个离子的无限稀释摩尔电导率(λ∞B),其能反映离子的溶剂化作用,是联系不同传递性质的重要纽带.建立了基团贡献法预测咪唑类阳离子和季铵类阳离子的无限稀释摩尔电导率模型(λ∞B-GCM),获得了咪唑中心离子[Im]、烷基铵[N]、甲基[—CH3]、亚甲基[—CH2—]、环氢[ring-H]、醚基[—O—]和羟基[—OH]等基团对无限稀释摩尔电导率的贡献值.建立的λ∞B-GCM不仅能反映不同基团对无限稀释摩尔电导率的影响,还能体现温度对无限稀释摩尔电导率的影响.研究结果表明,GCM预测的lnλ∞B含有超过70%的数据点的绝对相对偏差小于2%,绝对相对偏差超过5%的数据点不足1%,总的平均绝对相对偏差为1.57%,说明采用基团贡献法预测非常规阳离子无限稀释摩尔电导率是一种简单可靠的方法.
