Emergence is the phenomenon of collective behaviour that cannot predicted from considerations of the individual constituents but rather through complex interactions resulting in novel and diverse states of matter. A well-known example is the benzene ring, a loop of six carbon atoms, that can be further interconnected to create carbon nanotubes. Emergent behaviour in magnetic […]
Directed self-assembly offers an excellent route for the fabrication of nano-structured materials over large length scales. The final structure is determined by the interaction between the different building blocks, which can be, for example, steric, Coulomb or hydrophobic. From magnetic nano-particles the magnetic induction provides an additional design opportunity, with the particular advantage that the […]
Surfactants are amphiphilic molecules, meaning that one part is hydrophobic and the other hydrophilic. This leads to that they adsorb at interfaces and self-assembles in solution into various structures. These properties make surfactants important ingredients in several products as eg. detergents, emulsifiers and rheological modifiers. The extensive use of surfactants results in a significant environmental […]
Lipid based Nanoparticles (LNPs) constitute a potent nanotechnology used in drug and gene delivery. Indeed, the Covid19 vaccines by Pziffer and Moderna use this technology. LNP efficiency, however, is low (as determined by the protein expression capacity per loaded RNA) and efforts are continuously being made to increase their potency. For example, improving the uptake […]
Carbon materials are used in a wide range of applications from gas filtration to energy storage in batteries and supercapacitors.
