The activity is adapted from Kim et. al’s 2012 article in the Journal of Chemical Education (see references). Background Information: Teacher Background: Commercial products have frequently taken their inspiration from nature. For example, Velcro® resulted from a Swiss engineer, George Mestral, walking in the woods and wondering why burdock seeds stuck to his dog and his coat. Other bio-inspired products include adhesives, waterproof materials, and solar cells among many others. Scientists often look at nature to get ideas and designs for products that can help us. We call this study of nature biomimetics (see Resource section for further information). -

Occurrence of Reverse Side Effects in Corona Treatment of Dispersion
RESEARCH ARTICLE Occurrence of Reverse Side Effects in Corona Treatment of Dispersion-coated Paperboard and its Influence on Grease Barrier Properties PREFACE API 2015 Sami-Seppo Ovaska Ringaudas Rinkunas Lappeenranta University of Technology Vilnius University [email protected] [email protected] Tadeusz Lozovksi Robertas Maldzius Vilnius University & University of Bialystok Vilnius University Vilnius Branch [email protected] [email protected] Jonas Sidaravicius Leena-Sisko Johansson Vilnius Gediminas Technical University Aalto University [email protected] [email protected] Monika Österberg Kaj Backfolk Aalto University Lappeenranta University of Technology [email protected] [email protected] ABSTRACT The uncoated side of dispersion-barrier-coated paperboards was exposed to positive and negative direct current corona treatments in order to confirm the occurrence of backside treatment and clarify its effects on the usability of the paperboard. The main component of the coating dispersions was hydroxypropylated potato starch and the effects of talc and styrene-butadiene latex additions on backside treatment were evaluated. Coatings with a high talc proportion showed excellent initial grease resistance, but corona-induced strikethroughs caused a drastic decrease in grease penetration time. The root-mean-square roughness measurements revealed moderate surface roughening at the backside, indicating thus backside treatment. The alterations in surface free energies and rapeseed oil contact angles confirmed the occurrence of backside treatment. The high polarization potential of latex played a key role in these observations. At the same time, the inertity of talc had a stabilizing effect but it did not prevent backside treatment completely. X-ray photoelectron spectroscopy results verified that backside treatment occurs also when the barrier-coated side of the substrate is treated with corona, indicating that a dispersion coating layer does not prevent this undesired phenomenon. -
Oxygen-Reducing Enzymes in Coatings and Films for Active Packaging |
Kristin Johansson | Oxygen-reducing enzymes in coatings and films for active packaging | | Oxygen-reducing enzymes in coatings and films for active packaging Kristin Johansson Oxygen-reducing enzymes in coatings and films for active packaging Oxygen-reducing enzymes This work focused on investigating the possibility to produce oxygen-scavenging packaging materials based on oxygen-reducing enzymes. The enzymes were incorporated into a dispersion coating formulation applied onto a food- in coatings and films for packaging board using conventional laboratory coating techniques. The oxygen- reducing enzymes investigated included a glucose oxidase, an oxalate oxidase active packaging and three laccases originating from different organisms. All of the enzymes were successfully incorporated into a coating layer and could be reactivated after drying. For at least two of the enzymes, re-activation after drying was possible not only Kristin Johansson by using liquid water but also by using water vapour. Re-activation of the glucose oxidase and a laccase required relative humidities of greater than 75% and greater than 92%, respectively. Catalytic reduction of oxygen gas by glucose oxidase was promoted by creating 2013:38 an open structure through addition of clay to the coating formulation at a level above the critical pigment volume concentration. For laccase-catalysed reduction of oxygen gas, it was possible to use lignin derivatives as substrates for the enzymatic reaction. At 7°C all three laccases retained more than 20% of the activity they -
Tyvek ® Printing Guide
, China 兽桃 Mask Bag, designed by Shou Tao Tao Mask Bag, designed by Shou DuPont™ Tyvek ® Graphics EMEA Printability Guide Water Resistant Paper-like Light Tear Resistant Recyclable Printable DuPont™ Tyvek ® Graphics EMEA Printability Guide DuPont™ Tyvek® is a popular printing substrate due to its light weight, smooth surface, high dimensional stability, opacity, toughness and durability. Uncoated Tyvek® can be printed using most digital and commercial printing processes. Some digital presses and some aqueous ink jet printers require a special coating. Tyvek® can be printed either sheet or web-fed. Tyvek® can be printed the same way as paper, although some of its physical properties do require special attention. To achieve excellent print quality, both the designer and printer must understand the unique properties and characteristics of Tyvek®. Tyvek® is made of continuous high-density polyethylene filaments. By using heat and pressure, these filaments are bonded into a base material for printing which turns out to be neither paper, cloth nor plastic film, but it integrates the advantages of those three materials. Tyvek® material has a melting point of 135°C and is a water-resistant and non-absorbent material with superior dimensional stability, high strength, and a smooth matt surface. Most traditional printing technologies can be used for Tyvek® printing, as well as some digital printing. The following Tyvek® printing quick reference guidelines have been summarized based on our current knowledge and the relevant contents will be updated -
Pet Food Storage and Automated Feeder
Pet Food Storage and Automated Feeder by RYAN HALL Submitted to the MECHANICAL ENGINEERING TECHNOLOGY DEPARTMENT In Partial Fulfillment of the Requirements for the Degree of Bachelor of Science In MECHANICAL ENGINEERING TECHNOLOGY at the College of Applied Science University of Cincinnati May 2007 © ...... RyanHall The author hereby grants to the Mechanical Engineering Technology Department permission to reproduce and distribute copies of the thesis document in whole or in part. Signature of Author hanical Engineering Technology Certified by Kettil Cedercreutz, Thesis Advisor Accepted by ~~~-L~Dr. Muthar Al-Ubaidi, Department Head Mechanical Engineering Technology ABSTRACT The problem addressed in this technical report is the lack of an effective system for feeding the family pet. The basic system for completing this task is to have a pet food storage container, to hold the food until feeding, and having a bowl for the food which is filled by the pet owner as a chore designated for a specific person in the family. There are some distinct flaws with this system. Some of which are that the food storage container is unsightly and it takes up too much space, and the task of feeding the pet has become cumbersome and sometimes goes undone (or is done too much due to a lack of communication.) In order to eliminate this problem a Pet Food Storage and Automated Feeder was developed in order to store all pet food up and out of the way while being able to feed the pet with little or no effort and at programmable times. Many different steps were taken in the design and development of this project. -

Diving Into the Flexible Packaging Market
PUBLISHED NOVEMBER 2015 BAGS& POUCHES: Diving into the flexible packaging market SPONSORED BY: BAGS&POUCHES: Diving into the flexible packaging market WELCOME TO OUR FIRST eBOOK elcome to Packaging Strategies’ first eBook focusing on the flexible packaging mar- ket. This market is still expanding and growing each year. A report from Trans- W parency Market Research states that the global demand for flexible packaging was valued at USD 73.56 billion in 2012, and is expected to reach USD 99.10 billion in 2019. There is a lot of growth potential here, as the flexible packaging market spreads across several industries—including processing and packaging of pharmaceuticals, personal care products, household items, and food and beverages. Looking back through my years covering the packaging industry, I am amazed at how many more markets have adopted this packaging material, from baby food to laundry soap, motor oil and even body wash. It is an exciting time to be a part of the changes in the packaging industry. Look through this eBook for package inspiration, technical pieces, and articles that show successful product launches. Each article within the eBook focuses on this expanding market. We hope you enjoy reading all about the ever-growing segment of flexible packaging.
