Download or read book Mass Deacidification Systems written by Karen Turko and published by Association of Research Libr. This book was released on 1990 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Library administrators, faced with the problems of acid-paper deterioration, are examining mass deacidification procedures. Mass deacidification of acidic books while they are still physically sound and not yet brittle is the most cost-effective corrective action to extend the life of the paper. There are currently at least five mass deacidification processes available or under development, so that library administrators can begin to plan for the process. A brief and nontechnical description is given of the following five techniques: (1) DEZ (diethyl zinc), a process at the pilot stage; (2) Wei T'o, a liquified gas process that is in use in at least two locations; (3) BPA, the Book Preservation Associates System, currently available in New Jersey; (4) Bookkeeper, a process under development that involves magnesium oxide; and (5) the Lithco process, in the pilot stage. A table summarizes the properties, selection requirements, cycle times, and development stages of each of these processes. Considerations of process use, such as length of time required to treat a collection, potential damage or strengthening effects, and evaluation issues are reviewed. (Contains 103 references.) (SLD)
Download or read book Mass Deacidification written by Henk J. Porck and published by Washington : Commission on Preservation and Access. This book was released on 1996 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides an update of the possibilities and limitations of currently available mass deacidification methods, focusing on the major developments in research and application of the main operational systems. This study is intended primarily to support the development of a well-considered preservation policy by librarians and archivists, with a focus on the practical implications of mass deacidification rather than the technical details of the deacidification process. The study provides a brief history of the development of the technical process, a condensed description of the treatment principle, an overview of available research and test results, indicating the main advantages and disadvantages of the process, and an inventory of actual applications for five mass deacidification systems: (1) "Battelle"; (2) "Bookkeeper"; (3) "DEZ"; (4) "FMC"; and (5) "Wei T'o." Several other initiatives are also described, involving large-scale rather than mass treatment technologies, and essentially combining deacidification with strengthening of paper. The main findings are discussed within the framework of a critical evaluation of the current possibilities and limitations of mass deacidification in general. A list of contacts is provided.

Download or read book Nanotechnologies in the Conservation of Cultural Heritage written by Piero Baglioni and published by Springer. This book was released on 2014-11-20 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents novel applications of nanotechnology for the preservation of artistic and historical artifacts. It explains the scientific principles behind numerous nanomaterials and discusses their applications to different types of common movable and fixed artistic substrates. It starts with an overview of the nano-tools developed over the last three decades, such as dispersions of nanoparticles, micellar solutions, microemulsions and gels. Compared to traditional methods, these new tools have the benefit of considerably less impact on both the operators and the environment. Each chapter is dedicated to a specific type of cultural heritage material (wall and easel paintings, stone, paper, canvas and wood) starting with the main degradation paths and discussing protocols for the application of innovative nanomaterials-based tools for cleaning, consolidation, or deacidification, which represent the majority of the case studies encountered in restoration facilities, workshops and ateliers. The book provides step-by-step descriptions that are meant to support conservators in the application of these novel materials and methods. The aim of the book is to equip end-users and conservators with essential information and knowledge on the availability and applicability of different nano-materials and dispersed systems. While the book’s focus is on the practical aspects, interested readers will also find references to the relevant advanced colloid and material science literature. Main audience: Expert conservators, restorers and technical staff at conservation institutes and museums, students at conservation and restoration schools, and scientists who are new to the field of conservation of artistic and historical artifacts.

Download or read book Double Fold written by Nicholson Baker and published by Vintage. This book was released on 2002-08-13 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ostensible purpose of a library is to preserve the printed word. But for fifty years our country’s libraries–including the Library of Congress–have been doing just the opposite, destroying hundreds of thousands of historic newspapers and replacing them with microfilm copies that are difficult to read, lack all the color and quality of the original paper and illustrations, and deteriorate with age. With meticulous detective work and Baker’s well-known explanatory power, Double Fold reveals a secret history of microfilm lobbyists, former CIA agents, and warehouses where priceless archives are destroyed with a machine called a guillotine. Baker argues passionately for preservation, even cashing in his own retirement account to save one important archive–all twenty tons of it. Written the brilliant narrative style that Nicholson Baker fans have come to expect, Double Fold is a persuasive and often devastating book that may turn out to be The Jungle of the American library system.

Download or read book Cellulose written by Arnaud Lejeune and published by Nova Biomedical Books. This book was released on 2010-05-18 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cellulose is the most widely spread organic polymer found in nature, since it constitutes the main component of the membrane of plant cell. It is well-known that cellulose is a very important and fascinating biopolymer and an almost inexhaustible and renewable raw material. This book provides a synthesis of the old knowledge and the development of different studies which contribute to the understanding of the structure of cellulose allomorphs. In addition, cellulosic ethanol has been taken as a promising alternative energy source for the non-renewable fossil fuel. This book reviews the development of biochemical conversion of biomass materials into cellulosic ethanol, including previous achievements, current status, and future work. The various aspects of natural and accelerated ageing of cellulose are also presented and discussed. Other chapters in this book explore the basic principles of cellulose oxidation chemistry with a focus on different products of the reactions. The main part of the chapter focuses on both known and newly proposed applications of oxidised celluloses in medical, cosmetic, hygiene and food industry. A critical analysis is also made of the literature concerned with the kinetics of cellulose degradation. Furthermore, this book reviews bacterial cellulose (BC), an outstanding biomaterial with unique properties, including high water holding capacity, high crystallinity and ultrafine fibre network. These properties support a wide range of applications, in human and veterinary medicine, odonthology, pharmaceutical industry, acoustic and filter membranes, biotechnological devices and in the food and paper industry.
