The ability of nanocellulose and microfibrillated cellulose to provide strength in different products has been discussed and studied for a long time. MFC fibers are strong and lightweight and has large surface area which makes it an excellent candidate for strengthening aid. Some are referring to the composites containing MFC as being “the next world-changing supermaterial” (Gizmodo, 2014), while others believe that they can be part of car production (Financial Post 2017). So how is this actually working?
Three dimensional (3D) printing and tissue engineering are two fields that are currently developing rapidly and are both exciting technologies on their own. What if you combine them? That creates a new manufacturing process, bioprinting. It is a promising technology that might be the key to the on-demand tissue engineering. Microfibrillated cellulose (MFC) or nanocellulosic materials generally have an important role in the development.
Professor Lars Berglund, Head of the Biocomposites Division at KTH Royal Institute of Technology in Stockholm (Sweden), guides us through the relationship between cellulose and epoxy in this blog post. Not only do they matter, the properties created by this reaction are also excellent. Learn more about this in this weeks guest blog post.
Have you ever had problems with your inkjet printer? I bet that several people have experienced that during the years. The typical pattern is as follows: Your printer has been lying unused on your desk for weeks when suddenly you have an urgent need to print something. Often the outcome is that either the printing is messy or you end up having a blank paper in your hand. This is usually due to the drying of the ink on the printer head which is also known as nozzle clogging.
There is a lot of written and unwritten examples of defining sustainability. The following definition is given by Mirriam Webster: “a method of harvesting or using a resource so that the resource is not depleted or permanently damaged”. There are a lot of opinions on what’s sustainable. So what’s to know about this subject?
In many end products, and specifically in cosmetics, the first thing that attracts the consumer is the packaging format. This implies that the packaging should look good and luxurious as a sign of product performance.There are many possible technical solutions for packaging of cosmetic products: jars, spray bottles, pumpable dispensers. Have you wondered why some come in jars and others in spray bottles?
Solving problems you have or initiate new innovations can lead down quite different paths. Sometimes the urge to get rid of a problem can lead to many quick decisions, but what should one really look for in these types of situations? Should your standard tool box of problem solvers be used, or do you have the opportunity to focus on upgrading this box? In this blog post, I will try to show you some concrete examples why adding new tools to your tool box can improve your functionalities beyond your scope, using the microfibrillated cellulose as an example. Simply, why new functionality beats substitution.
Have you run into problems with incompatibilities between the surfactant you would like to use and other ingredients in your formulation? This is a common problem since surfactants are quite versatile in charge and chemical structure as well as in functionalities. This could for example lead to undesired interactions with oppositely charged ingredients.
In this blog post I will try to explain why this would not be an issue when you are planning to introduce microfibrillated cellulose (MFC) in your surfactant based system. You will also find a few recommendations on do’s and don’ts when mixing MFC and surfactants.
A lot of work on the MFC and nanocellulose is going on in an increased amount of business fields, all over the globe. We have seen a significant pick up in the strength and reinforcement functionalities of microfibrillated cellulose during the last 6-12 months, where its ability to provide significant strength improvements is clear. This week we have collected three new interesting areas of giving strength and barrier improvements, with exciting opportunities like bone construction with 3D printing, carbon fiber replacement, and water purification. This is your Exilva blog on exciting innovation, don’t miss out on our collection of news this week, and enjoy your reading!
