The present invention relates to a method for the production of a particle-containing aerosol, which includes comminutating a particle-containing cylinder. These aerosols are for example particularly suitable for use in the form of an aerosol stream in a coating process. The present invention further relates to particle-containing cylinders which can be dispersed and converted into aerosol form by simple methods.


An ink jet printer ink comprising effect pigments and organic solvents or solvent mixtures, wherein the effect pigments comprise a) aluminum effect pigments having a mean thickness in a range of 10 to 100 m and a d_(98 )value of the cumulative frequency distribution of the volume-averaged size distribution function of less than 15 m and/or b) pearlescent pigments having a d_(90 )value of the cumulative frequency distribution of the volume-averaged size distribution in a range of 3.5 to 15 m. The viscosity of the ink jet printer ink is 1 to mPa*s and the weight ratio of effect pigment to binder is 2 to 15. The invention further relates to the use of the ink jet printer ink.

The project proposal InFluENCE aims at improving the fundamental understanding and control of interfaces of a battery type based on Li-ion and Na-ion active materials: semi solid flow batteries (SSFB). The fact that the case study will be a SSFB set-up instead of classic lithium ion batteries is an asset, given that the methods and techniques developed are generic and could as well be implemented for conventional Li- and Na-ion systems for the techniques that are not concentrated on flow aspects. A main objective is the investigation and optimization of the interfaces developing between the electrolyte and the electrochemically active material particles in fluid electrodes. The acquired knowledge would allow the chemical and morphological optimization of active materials as well as the design of optimized interfacial layers (also called artificial Solid Electrolyte Interfaces, art-SEI) capable of warrant stable interfaces. A second main objective is the understanding and control the mechanical and conductive behaviours of the slurries. For this, it is necessary to determine the role of shape anisotropy and the overall nature (attractive or repulsive) of the short ranged interactions of the active materials besides the strength of the attractive forces for conductive nano-particles. The cross interaction should allow intimate contact between active material and the conductive particles. The experimental work is accompanied by thorough modelling to understand the physical phenomena occurring at the microscopic scale, to derive scaling rules towards macro-scale and to enable design recommendations leading to optimal interface behaviour (size of anodic and cathodic compartments, geometry of collectors, etc.).


The invention relates to a pigment which reflects IR radiation, comprising an IR-reflecting core, the IR-reflecting core being provided with a substantially enveloping coating which is transparent to IR radiation, and in that the IR-reflecting pigment is substantially white. The invention further relates to a process for producing these pigments and also to their use.
