The invention discloses a method for testing of injectable biomaterials and their performance in the treated materials, to obtain functional properties of the biomaterials and of the specimen injected with that biomaterial. The purpose of the method is to measure these properties during injection of a biomaterial into a target object, then measure the properties of a target object specimen after the injection, and then combine these results using material model-free data processing with possible prediction.

Method for measurement and model-free evaluation of injectable biomaterials properties

The invention discloses a method for in vitro testing of specimens, such as biomaterials, to obtain history-dependent, time-invariant functional materials properties using time-convolution and idempotent analysis. The purpose of the method is to measure these properties using a data processing without limitations of materials models, the properties linearity or material homogeneity.

In vitro method for measurement and model-free evaluation of time-invariant biomaterials functions

The invention relates to a method for in vitro testing of specimens, such as biomaterials or implants, wherein the method comprises at least immersing at least a part of the test specimen into a liquid media, controlling the liquid media, controlling surrounding environment, providing a predetermined non-destructive force to the specimen, and measuring reactions of the specimen or constituents of the liquid media. Further it relates to an apparatus for in vitro testing.

In vitro test method for implant materials

A phase change material (PCM) heat exchanger device comprising heat exchanger cells (,) operating on the regenerative countercurrent principle, one or more phase change material (PCM) accumulators () provided in the heat exchanger cells and one or more vortex tubes (). When the directions of the air, gas and liquid flows are cyclically reversed in the apparatus, energy is recovered into the heat exchanger cell and the PCM accumulator, and during the subsequent cycle, the energy is released from the heat exchanger cell and PCM accumulator. While one heat exchanger cell and PCM accumulator is being charged, the other heat exchanger cell and PCM accumulator is simultaneously discharged. Warm air exits a first outlet port while cold air exits a second outlet port of the one or more vortex tubes. The fluid flows heat or cool the heat exchanger cells and associated PCM accumulators.

The invention relates to a method for producing gaseous hydrogen and strong sulphuric acid (97-100 wt-%) simultaneously from sulphur dioxide gas and water. Sulphur dioxide gas stream is divided into two separate sub-streams, the first sub-stream is routed for water decomposition in a partial thermochemical cycle of the hydrogen and sulphuric acid production and the second sub-stream is fed to the oxidation of the sulphur dioxide to sulphur trioxide.
