【内容简介】
Poly(N-acylurea)–clay nanocomposites consisting of a modified montmorillonite and poly(N-acylurea) were prepared from which poly(amide-imide)–clay nanocomposites were subsequently obtained via the sequential self-repetitive reaction of poly(N-acylurea). The moderate Tg of poly(N-acylurea) allows the nonlinear optically active polymer to exhibit high poling efficiency; in situ poling and curing increased the Tgs of poly(amide-imide)–clay nanocomposites. Electro-optical coefficients, r33 of 17–20 pm/V (830 nm), were achieved; high temporal stability (120 °C) and waveguide optical losses of 3.4–3.9 dB/cm at 1310 nm were also obtained for poly(amide-imide)–clay nanocomposites.

【内容简介和体会】
08年9月份自然纳米的封面文章-纳米称的研究,声称可以做到单个金原子的测量精度;
本人以为文章及surplement中的实验数据没有出现原始的频谱数据,人为因素难以预计;另外射频测量过程中可能会受到金原子沉积过程中因为微波在腔壁反射率变化引起“共振”的移动。即,从实验数据上看不到"共振","共振"源于纳米线质量变化的结论更是虚无飘渺。不过质疑归质疑,这只是个人观点。

【文献题目】Characterization of the High-Pressure Structural Transition and Thermodynamic Properties in Sodium Chloride: A Computational Investigation on the Basis of the Density
Functional Theory
【期刊来源】J. Phys. Chem. B  2008, 112, 13898–13905

【内容简介】Using first-principles calculations, the elastic constants, the thermodynamic properties, and the structural phase
transition between the B1 (rocksalt) and the B2 (cesium chloride) phases of NaCl are investigated by means
of the pseudopotential plane-waves method. The calculations are performed within the generalized gradient
approximation to density functional theory with the Perdew-Burke-Ernzerhof exchange-correlation functional.
On the basis of the third-order Birch-Murnaghan equation of states, the transition pressure Pt between the
B1 phase and the B2 phase of NaCl is determined. The calculated values are generally speaking in good
agreement with experiments and with similar theoretical calculations. From the theoretical calculations, the
shear modulus, Young’s modulus, rigidity modulus, and Poisson’s ratio of NaCl are derived. According to
the quasi-harmonic Debye model, we estimated the Debye temperature of NaCl from the average sound
velocity. Moreover, the pressure derivatives of elastic constants, ∂C11/∂P, ∂C12/∂P, ∂C44/∂P, ∂S11/∂P, ∂S12/∂P,
and ∂S44/∂P, for NaCl crystal are investigated for the first time. This is a quantitative theoretical prediction
of the elastic and thermodynamic properties of NaCl, and it still awaits experimental confirmation.
