All You Ever Wanted to Know (and more) About UV-C LED’s and Applications

iuva
Sunday, May 15, 2016, 1:00 PM - 5:00 PM

Speaker: Jennifer Pagan,Ph.D., Aquisense, IUVA Member Company, Rajul Randive, Ph.D., Crystal IS, and Tatiana Koutchma, Novel Food Technologies

COURSE DESCRIPTION
UV-C LEDs have been available for a decade, mainly used as research tools and as low power instrumentation sources. Manufacturing developments in the last two years have opened the door for more widespread use of UV-C LEDs in disinfection applications. UV disinfection is often a last line of defense against food or water borne illnesses, and the use of UV is proliferating in a number of industries. As an emerging technology, employing UV-C LEDs as a disinfection solution requires a holistic design approach. UV-C LEDs offer more challenges, and potentially more benefits, than UV-A LEDs for systems level designers. The focus of the course will be on the following topics:

  1. Introduction to UV Disinfection
  2. Application of UV Disinfection in the food, beverage, and water industries
  3. Basics of UV-C LED technology
  4. Progress in UV-C LED manufacturing
  5. Adoption of UV-C LEDs in disinfection applications-what is current and what is coming
  6. UV-C LEDs in disinfection systems-design approaches

Questions answered by this course:

  • What is UV disinfection? Where is it used?
  • What is the technology behind a UV-C LED and what distinguishes a UV-C LED from a UV-A LED?
  • What is the current state of the art for UV-C LED production?
  • What are the implications of using UV-C LED at a systems level?
  • What are the current and future applications of UV-C LEDs?

Please Note: This short course will focus primarily on disinfection applications for UV-C LED.

UV/EB Professional Short Course (Undergraduate-Level)

Sunday, May 15, 2016, 1:00 PM - 5:00 PM

Faculty: Dr. Mike Idacavage, Colorado Photopolymer Solutions; Dr. Byron Christmas, University of Houston Downtown; Dr. Molly Hladik, Actega North America

WHO SHOULD ATTEND?
Attendees for this course should be UV/EB professionals who are employed in the polymer or coatings industry but who have not had an extensive college-level course in polymer chemistry or photo polymerization. As a minimum, attendees should have had an undergraduate course in general chemistry and at least one semester of organic chemistry.

COURSE DESCRIPTION
This half day course is designed to acquaint UV/EB chemists and other technical professionals with the fundamentals of polymer chemistry at an undergraduate level. It will involve an overview of step-growth and chain-growth polymerization processes with special emphasis on the latter. Specifically, it will cover the chemistry of free-radical and cationic polymerization processes including kinetic and thermodynamic aspects of the subject. The session will include a detailed discussion of the chemistry of the photo initiation process and will highlight a variety of polymer characterization techniques for UV/EB polymers. In addition, formulation strategies for UV and EB curing will be discussed along with brief discussions on a wide range of applications.

Advanced Photopolymerization Topics (Graduate level)

Sunday, May 15, 2016 1:00 PM - 5:00 PM

Faculty: Dr. Susan Bailey, IGM Resins; Dr Molly Hladik, Actega North America

WHO SHOULD ATTEND?

Attendees for this course may have extensive polymer or chemistry backgrounds who looking for an introduction into radiation curing. Alternatively UV/EB professionals that have experience in the field but are looking to gain new depth would also benefit.

COURSE DESCRIPTION
This course will begin with a brief review of photochemical and polymerization processes in UV/EB chemistry. From this common language, we will explore the implications of pigments, radiation sources, and environmental conditions on the cure reaction and performance of the final product. By focusing on the reactions and structure-property relationships, ways to understand and control the final product properties will be discussed. In addition to photo-initiated radical polymer chemistry, cationic, thiol-ene and hybrid chemistries will be used in examples. The course will cover implications for developing applications in low migration materials as well as requirements for inkjet, 3D printing and LED curing.

Design of Experiments for UV/EB Scientists and Engineers

Pt 1 - Monday, May 16, 6:30 PM - 9:00 PM
Pt 2 - Tuesday, May 17, NOON - 2:00 PM

FACULTY: Dr. Allan Guymon, University of Iowa

WHO SHOULD ATTEND?
This course will provide the foundation and motivation for using Design of Experiments to improve and optimize UV/EB curing processes and formulations. Students attending the course do not need previous experience in Design of Experiments or statistics. The course is appropriate for individuals with backgrounds ranging from technicians to Ph.D. scientists and engineers.

COURSE DESCRIPTION
Design of Experiments (DOE) is a powerful technique that allows the maximum amount of information to be obtained by performing the minimum number of experiments. For those in production, product design, or quality control, knowledge of DOE can dramatically enhance effectiveness in solving problems and optimizing systems. Most experiments not based on DOE concepts are two-dimensional, i.e. one variable is changed while a response is measured. DOE, on the other hand, varies all of the important variables simultaneously and systematically, thereby examining the response(s) in many dimensions.

Even with the great potential of DOE, few are familiar with its concepts. The goal of this course is to provide the basic tools needed for DOE implementation in the UV/EB industry. While DOE is based on statistical principles, primary emphasis will be placed on practical aspects in using and applying DOE techniques and on the motivation behind using DOE. Specific topics that will be addressed include:

• Background and History of DOE
• Steps in a DOE
• DOE Terminology
• Screening Designs
• Model Building Designs
• Mixture (Formulation) Designs

CEU CREDIT
Attendees taking this course will receive 0.6 CEU credits from the University of Iowa. CEU credit forms will be handed out to students the day of the course

Click Chemistry in Radiation Curing

Sunday, May 15, 2016 - 7:00 PM - 8:30 PM

Faculty: Christopher N. Bowman, University of Colorado Boulder

COURSE DESCRIPTION
A new paradigm encompassing several distinct chemical reactions and, more importantly, a generalized approach to molecular design and synthesis has been rapidly adopted in the fields of chemical synthesis, biotechnology, materials science, drug discovery, surface science, and polymer synthesis and modification. The Click Chemistry paradigm focuses on implementation of highly efficient reactions that achieve quantitative conversion under mild conditions. As such, these reactions represent ideal candidates for further development, understanding and implementation. In particular, the synergistic combination of these click chemistries with photochemical initiation and polymer formation has been used to afford 4D control of polymer formation, structure and function. Here, we will focus the discussion on the general click chemistry paradigm, specific examples of click reactions that are most relevant to radiation curing, the ability to initiate these reactions by exposure to light, and a survey of numerous examples of the implementation of click chemistry in radiation curable materials development. This discussion will focus on the great potential for click chemistry in radiation curing but also highlight some of the difficulties associated with bringing this new and powerful approach to chemical synthesis into the UV Curing field.
