Nanocellulose has been a hot topic for several years and numerous applications have been proposed, some of them more potential than the others. The major limitation for the wider use of nanocellulose has been the limited commercial availability. The term nanocellulose, however, covers several different types of nano- and microfibrillated and fibrillar cellulose products. One of those is bacterial cellulose which is also more commonly referred as bio-cellulose. It might come as a surprise for many of us, but bio-cellulose is in fact present in several commercially available products. One of those were the legendary Sony MDR-R10 headphones which were introduced already as early as 1988.
If you google the word medical device, you will get pictures of sophisticated hospital equipment and diagnostic devices. In practice, a term medical device is wider than just that and covers a range of different kinds of articles, starting from plasters and bandages to endosseous implants and implantable pacemakers, intended to be used for therapeutic purposes of humans or animals. We have previously written about the role of MFC in wound care products and today we are going to take a step deeper to the current status of nanocellulose in medical devices, especially topical and implantable ones.
You might have noticed how the air quality around us is changing constantly. Do you remember the last time that you have filled your lungs with fresh and clean air? Every day we are exposed to pollutants in the air we breathe - chemicals as well as fine particles - whether we are staying outdoors or indoors. This problem not only affects the people in developing countries, but the majority of the population on Earth.
Many household and industrial cleaners are strongly alkaline, highly acidic or contain oxidizing agents. This creates challenges when one would like thicken them or to have a gel formulation instead of the corresponding thin liquid version. In many cases, viscous, gel or foam formulations are preferred, as they ensure longer residence time on the vertical surfaces and are also safer to use as they are good at preventing any unwanted splashing. Today we will look at how MFC allows you to manufacture stable gel formulations at low to high pH as well as with oxidizing compounds, such as hydrogen peroxide.
Introducing a totally new material or technology to the market can often be challenging. Most people tend to have their favorite products which they know and prefer to work with. The natural way of testing of a new material is to compare it with the current products and apply the existing working routines to the first test runs. In some cases this approach might work but unfortunately in many cases it leads to a failure.
Today we will discuss about the important things that you should keep in mind when taking the first steps into the world of microfibrillated cellulose (MFC) and tell you how to gain the full potential out of it.
The transformation from cathode ray tubes to LCD displays has been rapid since the early 2000s. We now have thinner, lighter and bigger screens available with affordable prices. You have probably also seen pictures of flexible displays and read stories about flexible mobile phones and foldable screens. I'm sure many of you have also thought if we really need those and would it in the end be practical to have a foldable display in your pocket. Probably not, but flexible displays allow new product opportunities for many industries such as car industry and consumer products. However, one of the biggest drivers for the flexible displays is actually related to the manufacturing of the displays.
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 growing interest to increase the portion of bio-based components in various consumables. We have previously discussed about the challenges to incorporate microfibrillated cellulose (MFC) into composite materials with hydrophobic matrixes, such as PLA. Today we will take a step to even further and see how MFC can support the development of more environmentally friendly tires with high performance and durability.
The market for packaging and packaging solutions is expected to grow in the next four years due to factors like increased online shopping*. At the same time, the demand for sustainable packaging becomes more evident. In this article, we explore the compatibility of MFC with PLA and discuss what could be the benefits of such a mixture in various packaging products.
The biggest change in the coffee culture in recent years has been the way people prepare their coffee at home. An increasing number of households use single serve brewing (pods, capsules) for producing a fresh cup of coffee, resulting in an increased amount of waste. Replacing the current coffee packing materials is not straightforward, and obviously there are several challenges related to it. In this blog post I will play with the idea how microfibrillated cellulose (MFC) could support the development of new, more environmentally friendly, compostable or biodegradable coffee capsules.
