I regret to inform you that on the basis of the reports we are unable to accept the manuscript for publication in ADVANCED MATERIALS in its present form.However, if you were to substantially revise the manuscript taking into account the comments of the referees we would be pleased to have the manuscript reassessed.I am sorry not to be able to be more positive at this time but hope that this does not deter you from continuing to enjoy, and submit your work to, the journal.I look forward to hearing from you.Yours sincerely,Dr. David FlanaganDeputy Editor,Subject: Your Manuscript adma.,Subject: Your manuscript adma.200602256 for ADVANCED MATERIALSYOUR SUBMISSION OF: 03.10.2006_Dear Professor Fan,Thank you for your letter and the above-mentioned manuscript.I regret to inform you that we are still unable to accept the manuscript for publication in ADVANCED MATERIALS, a decision that is in accord with the opinion of the referee (see below).I am sorry not to be able to be more positive in this case but hope that you continue to enjoy ADVANCED MATERIALS and soon submit more work to the journal. I hope then to be able to offer you a better service.Yours sincerely,Dr. David FlanaganDeputy Editor,Subject: Your manuscript adma.,Dear Professor Fan,Thanks for your e-mail, in which you asked whether it is possible for me to reconsider my earlier decision to reject your above-mentioned revised manuscript. In principle every author of a rejected paper at ADVANCED MATERIALS has the right to appeal. For this it is necessary to submit a revised (or the original) manuscript and to present a rebuttal to the referees arguments. It certainly helps when an author sees major factual errors in the referees statements. If the whole case is only a matter of different opinions I recommend that one does not appeal.The rebuttal and the revised version are then sent to the referee whose recommendation caused the rejection. If necessary the whole case can be presented additionally to a court-of-appeal referee. When all statements are available, the editor makes the final decision.If you wish to start the appeal process, let me know and I will set the status of the above-mentioned manuscript to Manuscript to be revised on your homepage, and you can upload the revised version and rebuttal letter directly into our online system.Yours sincerelyDr. David FlanaganDeputy Editor,Dear Professor Fan,Thanks fo,Subject: Acceptance of Your Revised Manuscript adma.200602256 for ADVANCED MATERIALSPLEASE ANSWER BY: ASAP_Dear Professor Fan,Thank you for your manuscript.

Because competition for our limited space is becoming increasingly keen, I must decline papers that might have been accepted in the past. Guided by our constraints on space, two editors have concluded that your paper is likely to interest fewer readers than will others and that you and your readers will be better served if you submit the work elsewhere. While we are always sorry to decline papers for this reason, we hope that you will accept this verdict in the constructive spirit in which it is offered. We hope that our prompt response will enable you to submit your manuscript to a specialty journal, which will probably welcome this account of yourwork.,Thank you for allowing us to see it.,Sincerely, Dr. Carl WittwerAssociate Editor,RE: Clinical Chemistry MSID:,Subject: Acceptance of Your Manuscript adma.200701918 for ADVANCED MATERIALSADVANCED MATERIALSManuscript number: adma.200701918MS-Type: Communication Title: Enzyme-based multi-component optical nanoprobes for sequence-specific detection of DNA hybridizationCorrespondence Author: FanPLEASE ANSWER BY: ASAP_Dear Professor Fan,Thank you for your manuscript.

They observe picomolar detection limits (by eye!) and their approach is selective enough to deploy directly in blood serum.To the best of my knowledge no one has previously done such a good and compelling job of using a larger nanocrystal as a substrate for the attachment of both capture probes and reporter groups. The specificity, selectivity and sensitivity of the test-bed assay the authors developed are impressive, and I suspect the described technology will be applicable to many other assay formats.,IMPORTANCE: important (top,常见问题,SCI,简介,如何撰写,如何投稿,示例解析,常见问题,常见问题SCI简介如何撰写如何投稿示例解析常见问题,常见问题,中译英,少用长句,少用,In this paper (,可以用,In this study),少用或不用,Obviously, for the first time,重点在前(段落、句子),Incorrect,:,For the application in automobile interiors, this paper studies the nesting optimization problem in leather manufacturing.,Correct,:,This paper studies the nesting optimization problem in leather manufacturing for application in automobile interiors.,常见问题中译英,Which/that,Shown/showed,the results are,shown in,Figure 2,Such as/etc,Research work; Knowledge memory; Sketch map; Layout scheme; Output performance; Simulation results; Calculation results; Application results,How to,No:,How to find the optimal parameter is the main objective.,Yes:,Determining how to find the optimal parameter is the main objective.,阿拉伯数字不能开头,No:,12,parameters were selected for the experiment.,Yes:,Twelve,parameters were selected for the experiment.,Respectively,No:,The weights of the two experts are,respectively,0.600 and 0.400.,Yes:,The weights of the two experts are 0.600 and 0.400,respectively,.,Which/that,不要将名词作为形容词:,No,:,ATP formation; reaction product,Yes,:,formation of ATP; product of the reaction,单词“,this”,后面必须始终带有一个名词,这样它的指向才是明确的。,No,:,This is a fast reaction; This leads us to conclude,Yes,:,This reaction is fast; This observation leads us to conclude,始终用过去时态描述实验结果。,No,:,Addition of water gives product.,Yes,:,Addition of water gave product.,尽可能使用主动语态。,No,:,It was observed that the solution turned red.,Yes,:,The solution turned red.,或,We observed that the solution turned red.,比较式的主宾词要完整。,No,:,The yield was higher using bromine.,Yes,:,The yield was higher using bromine than chlorine.,不要将名词作为形容词:,Checklist,题目,题目概括了主要结果吗?,摘要,摘要叙述了你的故事吗?,前言,前言中的第一或第二句话,是否已经为你要回答的问题设好了序幕?你的描述是否“勾住”了读者呢?,你是否已经对你的科学问题进行了解释和阐述,而不是夸耀你的研究对象如何如何好?,你是否已经简要概括了与你要研究的问题相关的那些前人的工作?(要简要,不需要详细的文献综述)。,在前言的最后你是否意见很清楚地说明了你要回答的科学问题?,Checklist题目,方法,你是否已经简要地解释了你的研究对象(系统)的相关特征?,你是否已经详细说明了你的实验方法,其他的研究者可以来重复你的实验?方法要简洁,(,详细的内容可以放入,Supporting Information),。,你是否在叙述每个方法时,在开头都已经说明了为什么要进行这个测定?,你是否简要说明了你所使用的各种统计分析方法?,你所用的方法都与你的研究相关吗?,方法,结果,结果展示是否符合读者理解的逻辑性?(不一定要与你做的顺序相同),结果是否充分展示?(以图、表表示)。,文字是否充分解释说明了你的结果?而不是只是简单地告诉读者去看哪个图表?,结果描述是否是用该学科的术语来描述的?,你所展示的结果都是你的故事所需要的吗?,讨论,你是否强调了主要结果,并进行了解释?,你是否将结果上升到了一个更一般的层面?,讨论中的信息是否与你开始提出的问题相关?你的故事看起来严密吗?,结果,结论,你是否有一条很重要的建议?,图和表格,图表是否已经尽量简洁?,表头和图例是否全面?图表是否自明?读者不需要看文章是否就能明白其含义?,你在图中标出了标准误差吗?,你的散点图是否有一条合适的趋势线?,图例中是否有图注说明?,你对图的编辑是否符合出版的要求?,你的图表数量是否已经降到最低,但却足够清楚说明你的故事?,结论,Thank You !,Questions?,Thank You !Questions?,53,
