Cellulose Nitrate in Conservation
Author: Charles M. Selwitz
Publisher: Getty Publications
ISBN: 0892360984
Category : Art
Languages : en
Pages : 75
Book Description
This report attempts to isolate and separately examine each of the factors known to lead to cellulose nitrate decomposition, and then relate their contribution to the instability of the polymer when it is used as a bonding agent for ceramics and as a lacquer for metal objects. These factors include deterioration caused by heat, radiation, or acid impurities, or through the loss of plasticizer. There is, moreover, decomposition caused autocatalytically by the initial breakdown products. In particular, the publication examines new information on chemical changes under ambient conditions that has been developed recently through advances in analytical procedures such as chemiluminescence, X-ray scanning spectroscopy (ESCA), and more sophisticated viscometry. This new information will be added to the large body of data, collected over the past 150 years, on the instability of cellulose nitrate under more severe conditions.

Advances in Sonochemistry

Publisher: Elsevier
ISBN: 0080521606
Category : Technology & Engineering
Languages : en
Pages : 284
Book Description
Ultrasound in Environmental Protection focuses on one of the more significant developments in the subject - environmental remediation - providing an overview on both the fundamentals and applications of ultrasound in environmental protection, incorporating recent research and state-of-the-art information on the scientific basis, modes of use, and engineering developments. A broad spectrum of topics are covered: reactor design, sonochemical pollutant degradation, integrated unltrasonic/ biological treatment, ultrasound in disinfection, leaching by ultrasound, and ultrasonically enhanced removal of suspended solids.Ultrasound is generated and applied at frequencies from 20 kHz to several MHz. The physio-chemical parameters of the sonicated media, reactor design, applied intensity, and duration of sonication, dramatically influence the effects that can be achieved. It is hoped that this compilation will contribute to a better understanding and further development of sonochemistry as a clean technology not only for environmental remediation but also more generally.The foundation of this compilation was formed during a workshop that was held at the Technical University of Hamburg-Harburg, Germany, in March 1999. This was the first workshop to be devoted to 'Ultrasound in Environmental Engineering' and brought together experience and knowledge from a broad spectrum of disciplines including chemistry, biology, engineering, equipment manufacturing, and plant design.
