  • Surface Modification on Soda Lime and Alumina Silicate Glass Surfaces By
    Surface modification on soda lime and alumina silicate glass surfaces by Ion implantation – developments by AGC Amory Jacques, Benjamine Navet. AGC Plasma Technology Solutions, Rue Louis Blériot 12, 6041 Charleroi, Belgium 1. Introduction Ion implantation technologies have been used for many years in electronic industries but never on a large scale for materials surface treatment and especially for flat glass. This technology consists in bombarding in a vacuum chamber the surface of a material with highly energetic ions. The ions penetrate violently into the surface of the material, then stop and lose their energy because of a cascade of collisions. The surface reorganization and the implantation of ions into the surface of the material can modify the physico-chemical properties of various materials from polymers to metals, from glass to crystals. The judicious choice of the implanted ions allows obtaining re-alloying, amorphization or nano-restructuring of the surface, improving the material’s properties or adding new functionalities. 2. Ion source AGC uses the Hardion+ ion gun (Figure 1. left part) developed by its partner Ionics. This ion gun is based on the Electron Cyclotron Resonance (ECR) technology that allows the formation of multi-charged ions (dissociation of the molecule and up to 4 positive charges) thanks to the use of high frequency microwaves (10 GHz) and strong permanent magnets to confine the plasma. Since the ion kinetic energy is the product of its charge and the applied voltage, lower voltages are required to obtain high energy ions (40 kV to have N4+ ions with an energy of 160 keV) compared to ion gun generating mono-charged ions.

It is demonstrated that an optical waveguide can be obtained by a simple proton implantation in gallium lanthanum sulphide (GLS) glass. Two modes exist in the waveguide at a wavelength of 632.8 nm and the refractive index profile of the waveguide is reconstructed. The near-field pattern of the transmitted light is obtained, and the propagation loss is about 3.2 dB/cm. Based on the data of proton implanted waveguides, a titanium doped gallium lanthanum oxysulfide (Ti:GLSO) glass waveguide is fabricated by the double proton implantation. That waveguide does not exhibit tunneling effect, which is consistent with our design. Based on Raman analyses, we conclude that the glass matrix expansion due to nuclear damage causes the optical barrier formation. Little change in the guiding layer and low propagation loss present that Ti:GLSO glass waveguide may be a candidate of tunable lasers and has a possibility to take place of versatile but expensive Ti-sapphire lasers. Swift-heavy ion implantation (SHI), as a novel technique to fabricate waveguides, is explored to form waveguides in GLS and GLSO glasses.

Jules Henri Poincaré Abstract This thesis reports on the microstructural analysis of metal ion implanted Polydimethylsiloxane (PDMS), and on the characterization and modeling of its electrical and mechanical properties. Low energy (below 35 keV) metal ion implantation into PDMS forms metal nanoparticles in the top 10 nm to 120 nm of the polymer, creating a metal–insulator composite. Above a certain ion dose, the percolation threshold, the particles form a conductive path. By suitable choice of the volume-ratio between the two constituents (metal atoms and PDMS), one is able to create stretchable electrodes capable of sustaining uniaxial strains of up to 175% while remaining conductive, and remaining operational after 105 cycles at 30% strain. These outstanding properties are especially required for flexible electronic and for polymer actuators and sensors. Low energy metal ion implantation into 30 μm thick PDMS was performed at 10 keV and 35 keV with Low Energy Broad Beam Implanter (LEI), and at 2.5 keV, 5 keV and 10 keV with Filtered Cathode Vacuum Arc (FCVA).

Plaque biofilm—a major cause of caries, periodontitis and other dental diseases—is a complex community of bacteria or fungi that causes infection by protecting pathogenic microorganisms from external drug agents and escaping the host defense mechanisms. Antimicrobial nanoparticles are promising because of several advantages such as ultra-small sizes, large surface-area-to-mass ratio and special physical and chemical properties. To better summarize explorations of antimicrobial nanoparticles and provide directions for future studies, we present the following critical review. The keywords “nanoparticle,” “anti-infective or antibacterial or antimicrobial” and “dentistry” were retrieved from Pubmed, Scopus, Embase and Web of Science databases in the last five years. A total of 172 articles met the requirements were included and discussed in this review. The results show that superior antibacterial properties of nanoparticle biomaterials bring broad prospects in the oral field. This review presents the development, applications and underneath mechanisms of antibacterial nanoparticles in dentistry including restorative dentistry, endodontics, implantology, orthodontics, dental prostheses and periodontal field.

  • Using Ion Implantation for Figure Correction in Glass and Silicon Mirror Substrates for X-Ray Telescopes Brandon Chalifoux*A, Claire Burchb, Ralf K

Schattenburgc aDept. of Mechanical Engineering, MIT, Cambridge, MA, USA 02139 bHarvard University, Cambridge, MA, USA 02139 cSpace Nanotechnology Lab, MIT Kavli Institute, Cambridge, MA, USA 02139 dDept. of Aeronautics and Astronautics, MIT, Cambridge, MA USA 02139 *[email protected]; phone: (617) 253-3130; snl.mit.edu ABSTRACT Ion implantation is a method of correcting figure errors in thin silicon or glass substrates. For future high-resolution, high- throughput x-ray observatories, such figure correction may be critical for thin mirror substrates. Ion implantation into both glass and silicon results in surface stress, which bends the substrate. We demonstrate that this stress may be used to improve the surface figure of flat glass wafers. We then describe three effects of ion implantation in glass and silicon. The first effect is the stress resulting from the implanted ions, and the implications for figure correction with each material. Second, each material studied also shows some relaxation after the ion beam is removed; we report on the magnitude of this relaxation and its implications. Finally, the surface stress may affect the strength of implanted materials. We report on ring-on-ring strength tests conducted on implanted glass samples. Keywords: X-ray telescope mirrors, figure correction, ion implantation, glass, silicon 1. INTRODUCTION The Lynx X-ray telescope mission concept1 calls for a sub-arcsecond half-power diameter (HPD) angular resolution with large effective area that requires thin mirrors, which have low stiffness.

Therefore, there are enormous demands for innovative techniques which would improve the surface properties of implantable materials. Plasma technologies present one of the compelling ways to improve metal’s antibacterial activity; plasma treatment can significantly alter metal surfaces’ physicochemical properties, such as surface chemistry, roughness, wettability, surface charge, and crystallinity, which all play an important role in the biological response of medical materials. Herein, the most common plasma treatment techniques like plasma spraying, plasma immersion ion implantation, plasma vapor deposition, and plasma electrolytic oxidation as well as novel approaches based on gaseous plasma treatment of surfaces are gathered and presented. The latest results of different surface modification approaches and their influence on metals’ antibacterial surface properties are presented and critically discussed. The mechanisms involved in bactericidal effects of plasma-treated surfaces are discussed and novel results of surface modification of metal materials by highly reactive oxygen plasma are presented.

  • Surface Modification of Stainless Steel by Plasma-Based Fluorine and Silver Dual Ion Implantation and Deposition Yukari SHINONAGA and Kenji ARITA
    Dental Materials Journal 2009; 28(6): 735–742 Surface modification of stainless steel by plasma-based fluorine and silver dual ion implantation and deposition Yukari SHINONAGA and Kenji ARITA Department of Pediatric Dentistry, Social and Environmental Medicine, Integrated Sciences of Translational Research, Institute of Health Biosciences, The University of Tokushima Graduate School, Tokushima, Japan Corresponding author, Yukari SHINONAGA; E-mail: [email protected] The aims of this study were to modify dental device surface with fluorine and silver and to examine the effectiveness of this new surface modification method. Stainless steel plates were modified by plasma-based fluorine and silver ion implantation-deposition method. The surface characteristics and brushing abrasion resistance were evaluated by XPS, contact angle and brushing abrasion test. XPS spectra of modified specimens showed the peaks of fluoride and silver. These peaks were detected even after brushing abrasion test. Water contact angle significantly increased due to implantation-deposition of both fluorine and silver ions. Moreover, the contact angle of the modified specimen was significantly higher than that of fluorine only deposited specimen with the same number of brushing strokes. This study indicates that this new surface modification method of fluorine and silver ion implantation- deposition improved the brushing abrasion resistance and hydrophobic property making it a potential antimicrobial device.
