What has cellulose fibrils to do with air quality?

By Otto Soidinsalo 3. October 2017

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.

Why sustainable innovations will make our planet healthier; our globe is changing

By Mats Hjørnevik 26. September 2017

2017 has been a year of record storms and hurricanes. In August and September, the hurricanes lined up in the Atlantic and entered into populated areas one after another. The National Oceanic and Atmospheric Administration (NOAA) in the US reports that the statistics show an upward trend, also correlating to the size and magnitude of these hurricanes. The statistical data show uncertainties during the period from 1880s to 2016, but NOAA believes that the trend (based on research) shows a significant increase both in frequency and magnitude going forward. Why do I start my blog post on a nanocellulose blog with this? Well, because the link NOAA put between the Atlantic hurricane trends and global warming is obvious.

What is the effect of MFC on emulsion stability

By Rebecca Blell 19. September 2017

Have you heard the saying “Oil and water don’t mix”? This is a proverb said of things with such different natures that they cannot be combined. It is however not totally true since oil and water can be mixed into an emulsion. In many different industries such as cosmetics, pharma, paints, coatings, household products and many more, professionals mix different oils and water to create the desired performance of a product. They overcome the hurdle of “mixing” oil and water by using emulsifiers, surfactants and stabilizers. So how can MFC contribute?

MFC in cleaners - how to thicken your advanced cleaning products

By Otto Soidinsalo 12. September 2017

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.

Nanocellulose Research Review: Commercial update Sept. 2017

By Mats Hjørnevik 5. September 2017

The field of nanocellulose, fibrils of cellulose and microfibrillated cellulose is moving rapidly in the direction of full commercialization. Still, there are many undescribed application areas that are appearing, with higher and lower levels of innovation. In this week’s review, I am covering two very interesting stories; the increased interest from Japanese motor industry in utilizing the nanocellulose as components for their vehicles, and 3D printing of a nanocellulose alginate product.

Developing VOC-free formulation with microfibrillated cellulose

By Anni Karppinen 29. August 2017

Governments around the world are pushing industries to reduce their volatile organic compound (VOC) emissions. VOCs include very different type of chemicals but they may be dangerous to human health and therefore there is a common desire to reduce the use of them. Health effects vary from eye, nose and throat irritation to causing cancer.

Surfactants – a tool to tailor surface chemistry of MFC?

By Rebecca Blell 22. August 2017

One of the advantages of cellulosic materials (including nanocellulose and microfibrillated cellulose (MFC)) compared to synthetic materials, is their environmentally friendly profile as well as their biodegradability. This profile is impacted by the number of chemical reactions the product will undergo during the manufacturing process. It would therefore be favorable to obtain desired chemical properties via physical adsorption instead of chemical reactions.

In this blog post, you will find examples on possible effects of surface adsorbed surfactants on cellulosic materials.

3 things to remember when using MFC in the lab

By Otto Soidinsalo 15. August 2017

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.

Microfibrillated cellulose (MFC) in future advanced wound dressing

By Harald G. Rønneberg 8. August 2017

Wound dressings are advanced materials designed for securing sufficient healing of exterior wounds. These dressings have been around for a while, often containing hydrocolloids to be able to protect and absorb moist as well as increase the wound healing speed.  I will  give you a short overview of what types of wound dressings that are available and how microfibrillated cellulose (MFC) may give a new addition to this field of technology.

The role of MFC in flexible displays and electronics

By Otto Soidinsalo 1. August 2017

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.
