Over the last century, human activities have been affecting the global environment, most noticeably with the general increase in greenhouse gases, such as carbon dioxide (CO2). This rise in greenhouse gases has mainly been due to the upsurge in fossil fuel consumption over the last fifty years. This consumption has had a knock-on effect with global temperatures, with a general increase of 1°C over the last century and this is projected to rise by 2°C over the next century.1 This increase in temperature has also affected climate change by giving more extreme weather conditions. But how has this affected the construction industry? Have we been developing alternatives that could point us in a more bio-based direction?
Trends are clear; today's technology demands expect smaller and lighter devices, while at the same time the need for digital speed, pace and stamina is a potential deal breaker. How do you cope with this when developing tomorrows technology? In today's Topic Tuesday we serve you some interesting thoughts on how to keep your batteries safer, so you can focus on staying in front in the ongoing development marathon.
A fast viscosity recovery is good, and some times crucial, but that would also affect the leveling, right? In this weeks Topic Tuesday, we discuss how you can cope with the issue of getting fast recovery - and avoid sag - while getting your coating layer in level. We may also have some exciting ideas for you if you have problems with cracking.
There are several solutions to improve strength performance, and there are new materials available on the market. But how do you find the reinforcement additives and agents that provides the benefits you are looking for? And can this be done inline with the increased demand for sustainability at the same time? Spend a couple of minutes on this weeks blog post, and get some inputs and ideas on what to expect from one of these new materials.
A familiar problem for producers of coatings and polyolefins is what literature calls blocking. When blocking occurs, it is the coatings ability to create adhesion to itself that causes the problems. There are many available technologies for avoiding this, in which some are synthetically derived, and others are derived directly from nature. Could a bio-based alternative give you the effect you are looking for? If you are looking for some ideas, this is the blog post to read.
One of my favorite characteristics of the cellulose fibrils is its behavior when drying or involved in the drying process of a product system. I have learned through some of our conducted tests that cellulose fibrils can act in an interesting and often beneficial way towards obtaining desired end product characteristics. Most of the examples on how the fibrils influence the drying are related to coatings. I however believe that similar behavior is possible to observe in application areas where a tight control of dry-out properties is desired. Evaporation of solvents is often the main technique for drying in many applications. I will therefore focus my blog post this time on this specific drying technique. Let me share some very interesting insights into why cellulose fibrils are improving the products upon drying.
OK, so this case fascinated me a great deal. I have previously learned a lot on film forming properties, oxygen barrier properties and other related topics to this in the past. But recently I learned that the properties from microfibrillated cellulose and cellulose fibrils is starting to show potential in art preservation or conservation. But how does this take place, and what’s the main functionalities behind all this? I spent some time researching the subject, and today I am sharing my findings with you. Some key words: stability, transparency and mechanical strength. Dig in to learn more!
Making nanopaper is an good test on the characteristics of cellulose fibrils, and especially strength and durability. In this weeks blog from the Exilva blog, our H2020 partners at KTH are showing you how to make the nanopaper in a "step-by-step" practical example. The making of nanopaper quickly illustrates the strength performance you can get from this material once it forms paper or film. Spend a couple of minutes, and you will quickly understand why this material can take a leading part in the dual focus of increased sustainability and performance.
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.
Dust originating from abrasion of dry materials can cause a danger to the health and environment. One of the industries that is paying a lot of attention to dust control is the seed treatment industry. Seed treatments are an essential part of today’s agriculture and it means applying the crop protections products, like insecticides and fungicides, directly on the seeds before planting. This is regarded as an effective way to apply the crop protection products and can reduce the needed amount of the products in total. However, the applied substances can start wearing off from the seeds when they are transported and handled which can cause unhealthy dust.
