Book Description
The effect of exposure duration was also studied; when exposure duration increases, the crystallinity structure decreases and phase changes can occur which caused the broadening of the XRD peaks and IR bands. Oxidation in ambient oxygen gas at high pressures enhances the crystallinity of the Mn3O4 phase with no MnO2 formation.

Book Description
This Book's focus and intent is to impart an understanding of the practical application of atmospheric plasma for the advancement of a wide range of current and emerging technologies. The primary key feature of this book is the introduction of over thirteen years of practical experimental evidence of successful surface modifications by atmospheric plasma methods. It offers a handbook-based approach for leveraging and optimizing atmospheric plasma technologies which are currently in commercial use. It also offers a complete treatment of both basic plasma physics and industrial plasma processing with the intention of becoming a primary reference for students and professionals. The reader will learn the mechanisms which control and operate atmospheric plasma technologies and how these technologies can be leveraged to develop in-line continuous processing of a wide variety of substrates. Readers will gain an understanding of specific surface modification effects by atmospheric plasmas, and how to best characterize those modifications to optimize surface cleaning and functionalization for adhesion promotion. The book also features a series of chapters written to address practical surface modification effects of atmospheric plasmas within specific application markets, and a commercially-focused assessment of those effects.

Book Description
This book contains both the invited and the contributed papers presented at the Symposium "Surface Processing: Laser, Lamp, Plasma" held during the annual Spring Meeting of the European Materials Research Society in Strasbourg, France, June 16-19 1998. Surface processing of materials using laser, lamp or plasma is one of the most active fields of research in Europe and, as such, requires to be periodically reviewed at International Conference level. This year, the expanded surface processing symposium lasted for 3.5 days and, as an international forum, addressed not only fundamental questions in the field but also progress and new perspectives in various applications. The major subjects discussed during the meeting included fundamental process studies, modelling of growth mechanisms and surface modification, characterization of synthesised or modified materials, material modification at a nanometric scale, development of in-situ analytical techniques and applications towards device fabrication. About 200 papers were presented by some 120 participants.

Book Description
This book is a collection of invited papers (previously published in special issues of the Journal of Adhesion Science and Technology) written by internationally recognized researchers actively working in the field of plasma surface modification. It provides a current, comprehensive overview of the plasma treatment of polymers. In contrast to plasma polymerization, plasma surface modification reactions do not cause thin-film deposition, and can therefore only modify the surface properties of organic substrates. Plasma surface modifications are fast, efficient methods for improving the adhesion properties and other surface characteristics of a variety of polymeric materials. The focus of this volume is on adhesion phenomena, surface properties and the surface characterization of plasma-treated materials. This book opens with a critical review of the plasma surface modification of polymers for improved adhesion. The remainder of the papers are divided into two sections, one dealing with the characterization of plasma-treated surfaces and the second concerned with various practical applications of plasma-treated surfaces

Book Description
The purpose of this research has been to characterize the parameters of an Atmospheric Plasma Device used for surface modifications and functionalization of textile materials. Device parameters are determined in absence and presence of a substrate to quantify the optimal operational conditions. Neutral gas temperature profiles were determined for a variety of gas mixtures including 100% helium and helium with 1 or 2% reactive gases, such as oxygen and carbontetrafluoride. A plasma model was developed to solve for other plasma parameters including the electron-neutral collision frequency and the electron number density. Wool substrates were treated with various gas mixtures for a range of exposure durations and the effects of plasma treatment on weight, surface-functionality, and strength were assessed. Assessment methods include percent weight change calculations, energy dispersive X-ray spectroscopy (EDS), and tensile testing. In addition, cellulosic paper was exposed to 1% oxygen plasma to determine the feasibility of permanently grafting the anti-microbial agent HTCC (quaternized ammonium chitosan). The success of the bond was tested using Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), colorimetry, and percent weight change, and the permanency of the bond was tested though soxhlet extraction.

Book Description
This book addresses plasma modification of polyolefin surfaces. It comprises 21 chapters divided into three major sections. The first section covers the different techniques used for plasma modification of polyolefin surfaces and the effects of various gases as a surrounding medium, while the second provides a detailed analysis of the physics and chemistry of plasma modification and discusses various innovative characterization techniques, as well as ageing of the modified surface. It focuses on the analysis of changes in polymers’ surface chemistry using various spectroscopic techniques, and of changes in their surface morphology after plasma treatment using optical microscopy, electron microscopy and atomic force microscopy. In addition, it provides detailed information on the characterization of modified polymer surfaces. The book’s third and last section covers a range of applications of plasma-modified polyolefin surfaces varying from the packaging industry to the biomedical field, and shares valuable insights on the lifecycle analysis of plasma modification and modified surfaces.
