KGaA, Weinheim 1879 The fact that our readers not only appreciate the mix of materials science research presented within the pages of EDITORIAL Advanced Materials but also find it highly relevant to their research is reflected in the journal's citation figures. The jour- nal enjoyed a further substantial increase in Impact Factor[1] (IF) in 2003 to 7.305 (cf. 6.801 in 2002). Its sister journals Advanced Functional Materials and Chemical Vapor Deposi- tion have also faired well: The 2003 IF of Advanced Func- tional Materials was 4.798, which is very impressive for a full paper journal, and for the past several years the IF of Chemi- cal Vapor Deposition has been consistently steady at around 2 (2.071 in 2003Ðthe second highest in the films and coating category). This is a very good sign for the imminent indepen- dence of the journal (which can be subscribed to separately from Advanced Materials from 2005). Our author and referee services are also proving popular. The online submission and personal homepage system manu- scriptXpress has been used by our authors and referees since August 2003, and continual improvements are being made based on feedback from its users.

  • Reviewing Guidelines
    www.advmat.de www.afm-journal.de www.small-journal.de REVIEWING GUIDELINES 1. GENERAL We try to ensure that the reviewers we select are experts in the relevant field(s) and do not have a conflict of interest, and can thus assist us in evaluating whether a manuscript is suitable for publication. In rare cases it can happen that we select an inappropriate reviewer—if this occurs, please inform us immediately. Time is a scarce resource—especially for reviewers. Therefore, we pre-screen manuscripts for quality, relevance, and interest. Initially, we do not contact more than three reviewers. If a reviewer is not able to review a manuscript at all, or by the deadline provided, they should inform us immediately so that an alternative reviewer can be found. A short extension of the reviewing deadline is certainly possible; please let us know if this is required. Suggestions for suitable alternative reviewers are greatly appreciated, but reviewers should not approach alternative reviewers directly, as manuscripts should be kept confidential. If we do not hear from a reviewer we assume that a report will be sent in time. Reviewers may be asked to evaluate a revised version of a manuscript; however, we will not send a manuscript back for re-review if we judge the authors have not made a serious attempt to revise their manuscript in response to the reviewer comments. Reviewers can use the To-Do list on their personal homepage at www.manuscriptXpress.com to download a PDF of the manuscript for review and to upload their completed review.

    U.S. Citizenship Non-Precedent Decision of the and Immigration Administrative Appeals Office Services In Re: 7977790 Date: MAY 27, 2020 Appeal of Nebraska Service Center Decision Form 1-140, Immigrant Petition for Alien Worker (Extraordinary Ability) The Petitioner, an assistant project scientist engaged in biomolecular and biomaterials research, seeks classification as an individual of extraordinary ability. See Immigration and Nationality Act (the Act) section 203(b)(l)(A), 8 U.S.C. § 1153(b)(l)(A). This first preference classification makes immigrant visas available to those who can demonstrate their extraordinary ability through sustained national or international acclaim and whose achievements have been recognized in their field through extensive documentation. The Director of the Nebraska Service Center denied the petition, concluding that although the record established that the Petitioner satisfied the initial evidentiary requirements, it did not establish, as required, that the Petitioner has sustained national or international acclaim and is an individual in that small percentage at the very top of the field. The matter is now before us on appeal. The petitioner bears the burden of proof to demonstrate eligibility by a preponderance of the evidence. Section 291 of the Act; Matter of Chawathe, 25 I&N Dec. 369,375 (AAO 2010). The Administrative Appeals Office (AAO) reviews the questions in this matter de novo. See Matter of Christo 's Inc., 26 l&N Dec. 537, 537 n.2 (AAO 2015). Upon de nova review, we will dismiss the appeal. I.

  • Invitation to Join the International Advisory Board of Advanced Electronic Materials
    Invitation to join the International Advisory Board of Advanced Electronic Materials Dear Professor Martins, The Advanced Materials journal family is recognized around the world as a leading forum for cutting‐edge materials science research, and has served the community for a quarter of a century. The 2012 ISI impact factors of 14.8 for Advanced Materials, 10.0 for Advanced Energy Materials, and 9.8 for Advanced Functional Materials are testimony to the seminal nature of the research presented. We are currently working on the launch of the newest member of the family, Advanced Electronic Materials, a new space to feature the best research in the fields of electronic and magnetic materials; space that we hope will become the go‐to forum for scientists and engineers alike working in related areas. The journal’s launch is scheduled for January 2015, and given the excellent content which we see submitted in our other related journals, we expect to be as successful as our other recent sister‐journals Advanced Energy Materials, Advanced Healthcare Materials, Advanced Optical Materials, and Advanced Materials Interfaces. The Editorial Advisory Board of Advanced Electronic Materials will have a two‐tier structure. The smaller Executive Advisory Board is complemented by the larger International Advisory Board, and we are now actively recruiting recommended experts from the very top of the field to be part of this International Advisory Board. The members of the Executive Advisory Board are: Rainer Waser John Rogers Henning Sirringhaus Xiaohui Qiu Takao Someya Sang‐Woo Kim Advanced Electronic Materials hereby invites you to join its International Advisory Board.

Nonetheless, few-layer GaSe is not stable under ambient conditions and it tends to degrade over time. Here we combine atomic force microscopy, Raman spectroscopy and op- toelectronic measurements in photodetectors based on thin GaSe to study its long-term stability.

  • Strategies for Publishing
    Strategies for Publishing • Visualize content for papers early in the project • Generate research outlines that predict paper activity • Engage your students and postdocs in paper writing and planning. • Prioritize experiments to expedite paper completion over extension of unrelated data. • Generate paper outlines early! Basic Strategies Continued • Avoid Conference Proceedings (unless you are in an EE/CS related field) that preclude publication elsewhere • Shoot for the highest impact reasonable for the topic/accomplishment in your paper. • Be strategic about communications versus full papers • Recognize opportunity for papers in unexpected but important findings • Tell students that a paper = a thesis chapter - then encourage the papers to come first! (Avoid post-graduation writing as much as possible) Aspects of Writing • Look at the journal’s papers that you are aiming for, recognize style and subject matter that “fit”. • The introduction and the cover letter are key to persuading others the work is important • Avoid dry or esoteric language in titles • Choose the right title to ensure citation in the future. • Big name journals require a significant accomplishment - and data presented in a convincing and often striking manner (plan experiments accordingly). EMPHASIZE SIGNIFICANCE, IMPACT, SIGNIFICANCE!!! Keep track of impact factors in your field(s) 2006 Impact Factors (most rounded to one significant digit): From the RSC: From ACS: Soft Matter: 4.4 (see also weblink http://pubs.acs.org/4librarians/isi.html) Journal of Materials
