Combined Effect of Topography and Strontium on Mineralization
It has been established that the osteogenic expression and mineralization of bone-forming cells at surfaces of artificial materials depends on a number of cues including elastic modulus, chemistry, pattern shape as well as topography at the nanometer and micrometer scale. At iNANO, we have developed a topographical screening assay, which has already been able to provide further insight into the interaction between surface topographies and osteogenic differentiation. Furthermore, soluble factors may influence the differentiation as well. It has been shown both in vitro (data not published) and in vivo that Strontium (Sr) may guide mineralization.
Evanescent Wave Photocatalysis and Photopolymerisation for Surface Functionalisation
Anti-fouling materials are essential in industries ranging from the pharmaceutical industry to the energy industry. Making antifouling materials in a better, smarter, and cheaper way as well as understanding the chemistry and specifications of these materials, are thus very interesting areas of research.
Several graphene projects are run under SPOMAN. The material have huge potential for many industrial and research purposes. Functionalization and purification are key for the future potential of graphene.
Reversible Adhesives Based on Catechols and Metal Ions
Strong adhesion between different substrates is of highest importance in many different industries and is used both in protection of material-surfaces and in joining different materials together. Often materials are joined by physical joining, but it is also possible to do chemical joining of different materials. Especially when going for waterproof joining of different materials, the chemical approach may be most attractive.
According to the European PET Bottle Platform (EPBP), PET is the most recycled plastic packaging material in Europe with 1.8 million tons of PET bottles recycled in 2015. Clear and light blue PET bottles can be decontaminated and thereby upgraded to food grade recycled (r)PET, which gives them the potential to provide a high value market. The fraction of opaque rPET has very limited end-use applications meaning that sorting facilities systematically remove it from their recycling streams or reject it prior to the recycling process. The result is a high proportion of opaque PET bottles that cannot be recycled into current applications.
Synthesis of Self-immolative Disulfide Linear Polymers
The self-immolative linear polymers would be interesting materials for industrial and biomedical applications as a self-immolative polymer is a polymer which can be triggered by an external signal to depolymerize. It is simply a system which can dissolve on demand.
Chemical exfoliation and functionalization of graphene
Graphene is a rapidly developing area of research as the potential applications are very broad ranging. Graphene poses a range of interesting characteristics, making graphene a relevant material in many very different industries. Graphene production, however, do pose some challenges. Depending on the use of the graphene, the graphene must be of a certain quality and perhaps functionalized before being incorporated into relevant products or production lines.
Fiber Implementation in 3D Printing
CLIP (Continuous Liquid Interface Production) revolutionizes 3D printing as an industrial manufacturing process. CLIP makes it possible to make products up to 100x the speed of conventional DLS or SLA printers, and features isentropic material properties in the object comparable to those of injection molding. However, printing in fiber materials, such as carbon fiber, is still out of reach in this process or any other process using UV lights for curing the material. Fiber materials are used in a wide range of production lines of anything between shoes and cars.
This device can be used to measure static and dynamic friction with automatic repeatability, while choosing various parameters, including: Load (grams to 20-30 kg), resting time, temperature (-20 to ~ +100 C), sliding velocity (depending on DC-motor), and solid materials
The infusion table (IT) is used for vacuum assisted resin transfer molding (VARTM). VARTM finds it use in both industry, laboratory, and hobby use and gives flexible and light weight panels with comparable mechanical strength as various steel types. The IT consists of an insulated base with a silicone heater and a stainless steel surface.
Development of a micro-flow system for the formation and manipulation of droplets in a two-phase flow. The aim of the project involves a flow-system design capable of merging, mixing and sorting droplets through channel geometries.
