1. 相反/不同于
A. On the contrary, mononuclear complexes, called single-ion magnets (SIM), have shown hysteresis loops of butterfly/phonon bottleneck type, with negligible coercivity, and therefore with much shorter relaxation times of magnetization. (Angew. Chem. Int. Ed., 2014, 53: 4413–4417)

B. In contrast, the Dy compound has significantly larger value of the transversal magnetic moment already in the ground state (ca. 10⁻¹ μ_B), therefore allowing a fast QTM. （Angew. Chem. Int. Ed., 2014, 53: 4413–4417）

C. In contrast to the structural similarity of these complexes, their magnetic behavior exhibits strong divergence. (Angew. Chem. Int. Ed., 2014, 53: 4413–4417)

D. Contrary to other conducting polymer semiconductors, carbon nitride is
chemically and thermally stable and does not rely on complicated device manufacturing. (Nature materials, 2009, 8(1): 76-80.)

E. Unlike the spherical particles they are derived from that Rayleigh light-scatter in the blue, these nanoprisms exhibit scattering in the red, which could be useful in developing multicolor diagnostic labels on the basis not only of nanoparticle composition and size but also of shape. (Science 2001,  294, 1901-1903)

举例：

A. These stacks appear as nanorods in the two-dimensional TEM images, but tilting experiments confirm that they are nanoprisms. (Science 2001,  294, 1901-1903)

B. Note that TEM shows that about 20% of the nanoprisms are truncated. (Science 2001,  294, 1901-1903)

C. Therefore, these calculations not only allow us to identify the important features in the spectrum of the nanoprisms but also the subtle relation between particle shape and the frequency of the bands that make up their spectra. (Science 2001,  294, 1901-1903)

D. We observed a decrease in intensity of the characteristic surface plasmon band in the ultraviolet-visible (UV-Vis) spectroscopy for the spherical particles at λ_max = 400 nm with a concomitant growth of three new bands of λ_max = 335 (weak), 470 (medium), and 670 nm (strong), respectively. (Science 2001,  294, 1901-1903)

E. In this article, we present data demonstrating that opiate and nonopiate analgesia systems can be selectively activated by different environmental manipulations and describe the neural circuitry involved. (Science 1982, 216, 1185-1192)

F. This suggests that the cobalt in CoP has a partial positive charge (δ⁺), while the phosphorus has a partial negative charge (δ⁻), implying a transfer of electron density from Co to P. (Angew. Chem., 2014, 126: 6828–6832)

3. 如何指出当前研究的不足

A. Although these inorganic substructures can exhibit a high density of functional groups, such as bridging OH groups, and the substructures contribute significantly to the adsorption properties of the material, surprisingly little attention has been devoted to the post-synthetic functionalization of the inorganic units within MOFs. (Chem. Eur. J., 2013, 19: 5533–5536.)

B. Little is known, however, about the microstructure of this material. (Nature Materials 2013,12, 554–561)

C. So far, very little information is available, and only in the absorber film, not in the whole operational devices. （Nano Lett., 2014, 14 (2), pp 888–893）

D. In fact it should be noted that very little optimisation work has been carried out on these devices. (Chem. Commun., 2013, 49, 7893-7895)

E. By far the most architectures have been prepared using a solution processed perovskite material, yet a few examples have been reported that have used an evaporated perovskite layer. (Adv. Mater., 2014, 27: 1837–1841.)

F. Water balance issues have been effectively addressed in PEMFC technology through a large body of work encompassing imaging, detailed water content and water balance measurements, materials optimization and modeling, but very few of these activities have been undertaken for anion exchange membrane fuel cells,  primarily due to limited materials availability and device lifetime. (J. Polym. Sci. Part B: Polym. Phys., 2013, 51: 1727–1735)

G. However, none of these studies tested for Th17 memory, a recently identified T cell that specializes in controlling extracellular bacterial infections at mucosal surfaces. (PNAS, 2013, 111, 787–792)

H. However, uncertainty still remains as to the mechanism by which Li salt addition results in an extension of the cathodic reduction limit. (Energy Environ. Sci., 2014, 7, 232-250)

I. There have been a number of high profile cases where failure to identify the most stable crystal form of a drug has led to severe formulation problems in manufacture. (Chem. Soc. Rev., 2014, 43, 2080-2088)

J. However, these measurements systematically underestimate the amount of ordered material. ( Nature Materials 2013, 12, 1038–1044)
