Two Dutch researchers have developed a method for managing so-called batch productions. During a batch production, substances react in a reactor vessel according to a certain recipe to produce an end product. After the reaction the reactor is emptied and a new reaction with the same recipe is started.
Chemist Eric van Sprang and chemical engineer Henk-Jan Ramaker have developed a control method that also takes the relationship between various process parameters into account. The current methods of process control monitor all of the parameters during the reaction, such as pressure and temperature, separately. As a result of this the control process costs a lot of time and not all of the process disruptions are clearly visible.
Batch control is important for safety, the environment and product quality. The quality of the product made in a batch process depends on the various parameters involved in the chemical reaction. However, these parameters are never the same for all batches.

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
