最近读到一条有意思的社论,与大家分享一下: 众所周知,向期刊投稿的稿件数量要远远超出刊物有限篇幅内可以刊登的文章的数量,为了确保送交同行评审的稿件是达标的,审稿过程就显得尤为重要。ACS Nano 副编辑Jillian M. Buriak在最近一期(2010年9月28日) 的一篇 社论 中介绍了如何避免稿件在进入同行评审前被拒稿。第一,你的文章中是否有亮点足够吸引住读者的眼球。其次是新颖性、原创性,这与第一点紧密相关。有趣的是,这篇社论里面提到了编辑会通过网络搜索来判断文章的新颖性。第三,也是所有作者最容易实现的,就是使稿件的语言符合期刊的投稿要求。文章语言的好坏直接影响到读者对你工作的评价,评论中的一句话就提到如果稿件读起来就很松散,那么读者会自然而然地认为其科学性也同样松散。因此,提交语言过关的稿件以避免在进入同行评审前就被拒稿是至关重要的。有很多方法可以帮助你的稿件顺利进入同行评审,例如,在写作中使用简单易读的句子,让一位同事(两位更好)帮助通读全文,格外注意稿件是否符合期刊的投稿须知。语言清晰简洁、没有语法错误的稿件将为你争取到更多的机会让审稿人对文章的学术价值和作出正确的判断。 原文: As we all know, the number of manuscript submissions to journals vastly outweighs the amount of space journals have to publish. To handle this process and ensure that appropriate manuscripts are sent for peer review, the editorial process has become more important than ever. The editorial in a recent issue ACS Nano (Sept 28 2010) http://pubs.acs.org/doi/full/10.1021/nn1022318 by associate editor Jillian M. Buriak describes rejecting without review and how to avoid it. There are three points that editors use to select the best papers for peer review. First, does your manuscript have the wow factor, will it grab the attention of the journals readership. Second, which is closely related to the first, is novelty, is the work original. Interestingly, editors use internet searches, described in the editorial, to evaluate a manuscripts novelty. The third, and arguably the easiest to achieve for all researchers, is submitting a well-written manuscript that follows the journal requirements. The way a manuscript is written directly affects what people will think about your work, quoting from the editorial If your manuscript looks sloppy, then everyone will assume that your science is equally sloppy. Thus, it is imperative to only submit manuscripts of a high quality language and avoid being rejected without peer review. There are many ways to make sure your manuscript is not rejected prior to peer review including, write the manuscript in simple and easy to read sentences, have a colleague (or two!) read the manuscript and pay close attention to the journals guidelines for authors. By ensuring the manuscript is clear, concise, and free of grammatical errors will give the journal editors the best opportunity to judge your work on the scientific value and suitability for their journal.

ChuWei, Chernavskii,Khodakov, et al. J. Catal., 252 (2007) 215-230. Cobalt species in promoted cobalt alumina-supported FischerTropsch catalysts J Catal 252 (2007) 215-230 Abstract: The structure of cobalt species at different stages of the genesis of monometallic and Pt-promoted cobalt alumina-supported FischerTropsch catalysts was studied using X-ray diffraction, UVvisible spectroscopy, in situ X-ray absorption, in situ magnetic method, X-ray photoelectron spectroscopy, and DSCTGA thermal analysis. The catalysts were prepared by incipient wetness impregnation using solutions of cobalt nitrate and dihydrogen hexachloroplatinate. Both variation of catalyst calcination temperature between 473 and 773 K and promotion with 0.1 wt% of Pt had no significant affect on the size of supported Co3O4 crystallites. The size of cobalt oxide particles in the calcined catalysts seems to be influenced primarily by the pore diameter of the support. Cobalt reducibility was relatively low in monometallic cobalt alumina-supported catalysts and decreased as a function of catalyst calcination temperature. The effect was probably due to the formation of mixed surface compounds between Co3O4 and Al2O3 at higher calcination temperatures, which hinder cobalt reduction. Promotion with platinum spectacularly increased the rate of cobalt reduction; the promotion seemed to reduce the activation energy of the formation of cobalt metallic phases. Analysis of the magnetization data suggests that the presence of Pt led to the reduction of smaller cobalt oxide particles, which could not be reduced at the same conditions in the cobalt monometallic catalysts. Promotion of cobalt alumina-supported catalysts with small amounts of Pt resulted in a significant increase in FischerTropsch cobalt time yield. The efficient control of cobalt reducibility through catalyst calcination and promotion seems to be one of the key issues in the design of efficient cobalt alumina-supported FischerTropsch catalysts.

Vertically aligned, dense ZnO nanorod arrays were grown directly on zinc foils by a catalyst-free, low-temperature (450500 C) oxidization method. The zinc foils remain conductive even after the growth of ZnO nanorods on its surface. The success of this synthesis largely relies on the level of control over oxygen introduction. By replacing zinc foils with zinc microspheres, unique and sophisticated urchin-like ZnO nanorod assemblies can be readily obtained. ACS Nano , Article ASAP DOI: 10.1021/nn800759y
这个假期,除了陪爱人和儿子去逛了一下光谷步行街(吃喝玩乐一条龙,真的挺值得去的,儿子困的眼睛都睁不开了还不想回来呢),基本上都在实验室忙活,觉得还挺累的。刚刚看到下面在Nano Letters上的论文已经在线发表(ASAP)了,又给自己增添了一些动力。这篇论文经过反复的修改和补充重复与对照实验,有幸得到审稿人的肯定,得以发表,本来还有一些性能结果,不过主编认为仅仅组装与择优取向排布已经是比较系统的工作了,没必要再加性能进去。 欢迎各位同行提出宝贵的建议和评论。并祝各位朋友在新的一年里工作顺利,身体健康,合家欢乐!

This years Nobel Prize of Chemistry went to three scientists who made significant contribution toward marking proteins in the living cell with Green Fluorescent Protein (GFP). Nobel prizes usually cause a sensation in the media but not among real researchers. Since if the discovery could be bestowed with the honor, it has already been widely known or widely used for quite a while. Now what researchers really care is what will come after Green Fluorescent Protein technology since GFP certainly has some limits. There are still many urgent demands from biologists which GFP can not meet. Current technology of protein dyes The revolution of GFP is to enable researchers to see when and where certain proteins are expressed. You could even associate the intensity of GFP with the protein concentration. Then you can derive some quantitative measurements for your modeling. The most impressed GFP image which I have seen is from Robert Kays research of the Chemotaxis of E Coli. He showed that when certain genes of molecular motors are knocked out, the cell can not move at all even GFP images show signaling proteins are correctly synthesized in the chemical gradient direction. Fig. 1 GFP to show the expression of Chemotaxis signaling proteins You can see a video here: http://www2.mrc-lmb.cam.ac.uk/groups/rrk/movie2.html Gene Myers from Janelia Farm Research campus of HMMI even introduced computerized visual identification to scan thousands of GFP images from genome-wide experiments. Therefore, not just single biochemical pathway could be made clear from GFP. The total protein interaction network dynamics could be inferred from genome-wide protein expression pattern with GFP. Limitation of protein dyes Protein dyes technology is hugely improved fby the mutations leading to various colors and increased Fluoresce in the Roger Tiens hands. However, the number of different color is still too limited with the respect to the increasing demands from biologists to see the expression patterns of the large number of different proteins simultaneously. We could learn when and where proteins are expressed by GFP but the number is usually very small. Fig. 2 Three color scheme GFP image for cell mitosis To make up for this limitation, the current high-throughput technology is usually used to quench cells and extract cell extracts every few minutes or even hours to capture the cell dynamics. Then concentrations of different proteins are separated by mass-spectrometer. However, there are several disadvantages: First, we lose the information of spatial distribution of those proteins. Secondly, it is highly efforts-consuming job so it is quite coarse-grained in time resolution. Thirdly, there certainly are some unexpected changes when we crash the cells. Therefore, high-throughput mass-spectrometry technology can handle with hundreds of proteins at the same time but lose much information of space and time. Outlook of protein marking technology It is urgent to develop a new technology to mark hundreds of different proteins simultaneously and to detect their expression without any damage to the cell. There are many wild speculations. Nobody has really developed some feasible technology, yet. One possibility is to use some proteins with hundreds of different conformations if it is mutated. They can be attached to any proteins which the biologists are interested. Then an nano-NMR array scanner could be used to scan the cell for its spatial-temporary protein expression pattern. There is no need for the nano-scanner to have a high resolution. It is enough if it can distinguish various shapes of mutated protein markers. However, it has to be fast enough to give a better time resolution. Feynman once said that what Biology needs is to see better at the atomic Level: We have friends in other fields--in biology, for instance. We physicists often look at them and say, You know the reason you fellows are making so little progress? (Actually I don't know any field where they are making more rapid progress than they are in biology today.) You should use more mathematics, like we do. They could answer us--but they're so polite, so I'll answer for them: What you should do in order for us to make more rapid progress is to make the electron microscope 100 times better. This observation is still valid if we want to study the details of the biochemical reactions. However, if we want to study the dynamics of hundreds or even thousands of proteins within one cell, a automatic protein marking and detecting technique with high spatial-temporary resolution is what biologists desperately need. This years Nobel Prize does not signify the beginning of the end of protein marking technology; instead, it is just the end of the beginning. END
