Nano-Micro Letters 最新在线文章(Open-Access): 大面积定向单晶有机纳米带阵列:控制生长、晶体管和LED驱动应用 论文概述 基于有机微纳晶体的有机场效应晶体管(OFET)在过去十几年受到广泛关注,目前报道的载流子迁移率已获得极大提高,在高性能、廉价有机电子领域具有广阔的应用前景。有机微纳晶体的定向排布及阵列化有助于降低寄生漏电流,提高器件的均匀性和可重复性。然而如何高效制备晶体生长方向一致的大面积有机微纳晶体阵列是面临的重要技术挑战。现有沉积方法往往需要生长模板、复杂设备及工序,不利于简便及大面积制备,阻碍了其商业化应用前景。有鉴于此,苏州大学功能纳米与软物质研究院(FUNSOM)的揭建胜教授课题组利用一种简便的液相浸涂方法,成功制备出大面积、定向排布的BPEA和TIPS-PEN有机单晶纳米带阵列。该方法满足大批量制备的需求:在 5 × 10 cm^2硅片基底上可覆盖60%的定向晶体。在BPEA和TIPS-PEN阵列基础上所制备的OFET空穴迁移率分别超过2.0 和3.0 cm^2/V s,同时电流开关比(Ion/Ioff) 大于109。该OFET完全满足发光二极管(LED)驱动的性能要求。 文章引用信息 Wei Wang, Liang Wang, Gaole Dai, Wei Deng, Xiujuan Zhang, Jiansheng Jie, XiaohongZhang, Controlled Growth of Large-Area Aligned Single-Crystalline OrganicNanoribbon Arrays for Transistors and Light-Emitting Diodes Driving.

读文献偶感
热度 1 redrum 2011-8-3 20:23
今天读了一篇新的ACS Nano :《 Synthesis and Catalytic Properties of Au–Pd Nanoflowers 》( DOI: 10.1021/nn201161m ),受益匪浅。看完后小有感触,那就是做科学一定要实事求是、认真自信。文中作者成功地合成出了形貌很新颖独特的以金为心以钯为瓣的纳米花,并进行了催化Suzuki偶联的催化应用。结果与一般的结构相比,催化活性却没有提高。一般说来,我们合成一种材料,总是想找到一种出众的应用,那么一篇文章也就出来了。如果所尝试的应用效果不好,一定大失所望,可能会就此打住并再去找别的应用,也可能会怀疑自己实验结果有问题,甚而有的人会牵强附会地说自己材料的优点。可是本文作者却并没有这样做,他们详细地研究了催化机理,最后得出结论:该类型催化剂与形貌关系不大,并提出这一反应不适合作为研究结构敏感催化剂的模型反应,这无疑也是一个很大的贡献,很有“山穷水复疑无路,柳暗花明又一村”的味道。这篇paper告诉我,科研,一定要灵活,要认真,要大胆探索,要实事求是。只有这样,才能做好啊。。。

label or label free proteomcis
sunymor 2011-5-27 21:24
今天和Thermal工程师交流一下,谈到label free定量的问题,我是一直想做这种的,因为简单,线性范围较宽,可以同时比较多个样品。不过工程师不建议我这样做,原因是设备条件要求比较高,例如要用nano liter的色谱泵,商品化的nano column and emmiter,以保证每次进样的重复性。这么说来,我目前的条件还不能做,因为用的是micro liter进样,通过分流达到的纳升进样,这样流速其实很不稳定。其次,我使用手工的毛细管填料柱,手工拉制emmiter,这些硬伤无法保证样品的重复性。 预实验表明,用如此系统,分析重复仅有60%左右的重复结果,若是不同样品进行label free,真是不行的。 如此看来,只能尽量提高标记样品的鉴定率了,标记效率还可以,不用考虑。 另外,磷酸化肽段真是讨厌,总是那么少,用Orbitrap velos也没好多少。 有一段时间了,有点烦乱,是自己的问题。

[转载]如何避免稿件在同行评审前被Pass
liwenbianji 2010-10-14 15:08
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.

昨天China Nano2009会议正式在北京国际会议中心拉开序幕。很遗憾没能做成志愿者,不能为大会出点力。但是,还是有机会进入会场聆听大师们现身说法。 此次会议的注册人数再创历史新高(中国的传媒比较喜欢用这句话)。偌大的会场,都是黑压压的人群。大会准备工作也不错。音响,投影仪等都合适。宿舍一做志愿者哥们每天都拖着疲惫的身体回来。真的需要好好感谢他们。领导讲完话,就开始大会报告,请的都是牛人,可能是综合原因,听的有点犯困。中午是自行解决午餐,轩轩带着我们跑到麦当劳,吃了点东西,又急急忙忙的往会场赶,第一会场讲纳米材料的,最爆满,特别是唐智勇老师做报告时,人都挤到外边。师兄和师姐选择听自主装,而我和原原去了第二会场,导师正好也在,没座位了,就蹲在地上,不过也值,报告很精彩,思路很新,参杂N的半导体复合结构能够更好的实现电子-空穴分离。之后cui yi的报告也很精彩,工作很出色,讲的特有范,偶像!其他的报告,印象一般,今天的也是。 大会的一个附加品就是很多与纳米相关的展台,各种公司都有。在纳米粒子制备的Ocean公司的展台前观赏了很久,了解了下他们产品的制备,来源以及合作的事项。感觉之一,产品还真赚钱。 总而言之,大会是成功的,大部分人应该也是满意的。但是可能全国的大会都存在这样的通病,譬如说普通报告质量不高,例如一个量子点核壳结构的报告,基本是原先的方法组合;真正有价值的还是邀请报告,大部分的文章都是混毕业的吧。在此也勉励自己,每个报告都应拿的出手。加油! 附:会议新闻通告 2009中国国际纳米科学技术会议召开 2009中国国际纳米科学技术会议(ChinaNANO 2009)于2009年9月1日在北京国际会议中心召开。这是继2005、2007中国国际纳米科学技术会议(ChinaNANO 2005、ChinaNANO 2007)在北京成功举办之后,由国家纳米科技指导协调委员会主办、国家纳米科学中心承办的第三次国际会议。中国科学院常务副院长、国家纳米科技指导协调委员会副主任白春礼院士担任大会主席。本次大会得到教育部、科技部、中国科学院、国家自然科学基金委员会、中国科协等单位的大力支持。 本次大会旨在促进国际纳米科技前沿问题的研讨与交流,进一步提高我国纳米科技的整体研究水平和自主创新能力,推动我国纳米科技界与国际同行的合作。会议将围绕纳米信息材料、纳米能源与环境材料、纳米器件与传感器、纳米医药学和生物医学工程、纳米加工与纳米计量、纳米结构表征、纳米光学与表面等离激元学、纳米结构建模与模拟等领域,分为八个分会展开广泛而深入的学术交流。会议共收到论文摘要1300多篇,来自美国、俄罗斯、日本、英国、德国、法国、瑞典、丹麦、挪威、加拿大、意大利、比利时、西班牙、荷兰、波兰、印度、韩国、马来西亚、伊朗、巴西、泰国和中国等近40个国家和地区的1500余名代表到会注册,其中海外学者近500人。 大会邀请德国卡尔尔斯鲁厄研究中心Horst Hahn教授、美国加州大学纳米技术研究所主任Paul Weiss教授、日本东北大学校长Akihisa Inoue教授、丹麦奥尔胡斯大学纳米科学研究中心主任Flemming Besenbacher教授、日本东京大学Hiroyuki Sakaki教授、美国斯坦福大学戴宏杰教授和美国德克萨斯大学Mauro Ferrari教授等7位国际纳米科技界活跃的专家将作大会特邀报告,同时邀请了美国、日本、英国、德国、瑞士等国家和地区的68位科学家作分会邀请报告。 全国人大常务委员会副委员长、中国科协主席韩启德院士,科技部曹健林副部长,北京大学周其凤校长等中国科技界、教育界领导同志莅临了大会开幕式并致辞。同时,中国科学院、教育部、国家自然科学基金委还向大会发来贺电。 作为中国最大规模的纳米科技国际会议,两年一度的中国国际纳米科学技术会议的召开不仅扩大了我国在国际纳米科技界的影响和地位,促进了国际纳米科技界的学术交流,而且将有力地推动我国纳米科技事业的持续、健康和快速发展。

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.

Aligned ZnO Nanorod Arrays Grown Directly on Zinc Foils and Zinc Spheres by a Lo
zjgu 2009-2-4 00:59
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

在Nano Letters上的第一篇文章
麦立强 2009-1-3 23:55
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!

谁将是荧光蛋白质的后继者?

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
