Adsorption is the most common method for controlling volatile organic compounds (VOCs) emission from automotive painting process. However, unwanted accumulation of adsorbate during cycling (heel buildup) is a common challenge in this process. The objective of this research is to identify the impact of regeneration conditions such as temperature, heating rate and purge flow rate on heel buildup and adsorption capacity. For this purpose, five cycle adsorption/regeneration experiments using 1,2,4-trimethylbenzene (TMB) on activated carbon fiber cloth (ACFC) were completed using resistive heating. Increasing temperature from 288 to 400°C worsened adsorbent performance, as indicated by smaller adsorption capacity and larger heel buildup. Decreasing heating rate from 100 to 5°C/min and increasing flow rate from 5 to 0.1 SLPM decreased heel buildup (by 56% and 90%, respectively) and capacity loss (by 85% and 97%, respectively). These observations are the result of carbon deposition due to thermal degradation of TMB during regeneration which is the impact of rapid adsorbent heating rates. The results of this work will help to optimize regeneration condition to allow fast desorption with minimal adsorbate decomposition.

High surface area, a microporous structure, and a high degree of surface reactivity make activated carbons versatile adsorbents, particularly effective in the adsorption of organic and inorganic pollutants from aqueous solutions. Activated Carbon Adsorption introduces the parameters and mechanisms involved in the activated carbon adsorption

The relatively new technique of solid phase microextraction (SPME) is an important tool to prepare samples both in the lab and on-site. SPME is a "green" technology because it eliminates organic solvents from analytical laboratory and can be used in environmental, food and fragrance, and forensic and drug analysis. This handbook offers a thorough background of the theory and practical implementation of SPME. SPME protocols are presented outlining each stage of the method and providing useful tips and potential pitfalls. In addition, devices and fiber coatings, automated SPME systems, SPME method development, and In Vivo applications are discussed. This handbook is essential for its discussion of the latest SPME developments as well as its in depth information on the history, theory, and practical application of the method. - Practical application of Solid Phase Microextraction methods including detailed steps - Provides history of extraction methods to better understand the process - Suitable for all levels, from beginning student to experienced practitioner

This easy-to-consult guide examines the most advanced techniques in the radiological evaluation of the disc and degenerative disc disease, using conventional, functional, dynamic and advanced imaging. It provides clear information on a range of CT, X-ray, and MRI guided techniques, presents all disc treatments in connection with symptomatic disc herniations, evaluates conservative, chemical (ESI, steroid, Ozone, ethanol gel injections) and physical treatments (coblation, laser, decompressors, endoscopy), and assesses the possibility of repairing and/or regenerating the disc in the context of reversible disc degeneration. Like other books in the Springer series New Procedures in Spinal Interventional Neuroradiology, this practice-oriented volume will fill a significant gap in the literature and meet the need expressed by many specialists (interventional neuroradiologists and radiologists, neurosurgeons, and orthopedists) for a topical and handy guide that specifically illustrates the currently available materials and methods.

Our interest in Mulhouse for carbon black and soot began some 30 years ago when J.B. Donnet developed the concept of surface chemistry of carbon and its involvement in interactions with gas, liquid and solid phases. In the late sixties, we began to study soot formation in pyrolytic systems and later on in flames. The idea of organ1z1ng a meeting on soot formation originated some four or five years ago, through discussions among Professor J.B. Howard, Dr. A. D'Alessio and ourselves. At that time the scientific community was becoming aware of the necessity to strictly control soot formation and emission. Being involved in the study of surface properties of carbon black as well as of formation of soot, we realized that the combustion community was not always fully aware of the progress made by the physical-chemists on carbon black. Reciprocally, the carbon specialists were often ignoring the research carried out on soot in flames. One objective of this workshop was to stimulate discussions between these two scientific communities. During the preparation of the meeting, and especially during the review process by the Material Science Committee of the Scientific Affairs Division of N.A.T.O. the toxicological aspect emerged as being an important component to be addressed during the workshop. To reflect these preoccupations we invited biologists, physical chemists and engineers, all leaders in their field. The final programme is a compromise of the different aspects of the subject and was divided in five sessions.
