Unfortunately, reactions going with extensive calorification and/or participation of unstable components and reaction products are not infrequent in chemistry. Here lies potential hazard of chemical manufacturing. Even minor deviations from technology and simply changes in reagents’ storage or transportation conditions, to say nothing about hazard situations, for instance, sudden power outages, may result in unexpected consequences. Therefore, emergency events evolution in the most inconceivable situation of chemical manufacturing should be considered in advance and an appropriate protection system should be elaborated. The saying that “forewarned is forearmed” is true in chemistry like nowhere else.
The new generation of chemical manufacturing protection systems is being developed by researchers from the Russian Research Center “Applied Chemistry” in cooperation with the Open Joint Stock Company “Khiminform” and foreign colleagues from the “Berwanger” company. In the course of the project which is sponsored by the CRDF international foundation and Rosnauka, the authors plan to design the software that would not only allow to discover trouble spots in manufacturing processes at the chemical and petrochemical industry enterprises, but also to ensure safety of these processes. This deals with equipment protection from abnormal high pressures in case of emergency, in other words – i.e., this deals with explosions and the ways to fight with them.
Naturally, chemical plants use double and triple security circuits now, as professionals put it, particularly in the most potentially hazardous sections of manufacturing process. However, what these trouble spots requiring additional protection are gets sometimes apparent only when the process is already beyond control. However, explosion is not the price to be paid in order to learn how the equipment would behave in emergency event. This is certainly obvious. As well as the fact that chemical and physical processes proceeding in the damaged reactor are so complicated that the researchers have failed so far to forecast them and particularly to develop really efficient equipment to protect reactors from explosion.

Solar cells based on perovskite compounds could soon make electricity generation from sunlight even more efficient and cheaper. The laboratory efficiency of these perovskite solar cells already exceeds that of the well-known silicon solar cells. An international team led by Stefan Weber from the Max Planck Institute for Polymer Research (MPI-P) in Mainz has found microscopic structures in perovskite crystals that can guide the charge transport in the solar cell. Clever alignment of these "electron highways" could make perovskite solar cells even more powerful.
Solar cells convert sunlight into electricity. During this process, the electrons of the material inside the cell absorb the energy of the light....
Empa researchers have succeeded in applying aerogels to microelectronics: Aerogels based on cellulose nanofibers can effectively shield electromagnetic radiation over a wide frequency range – and they are unrivalled in terms of weight.
Electric motors and electronic devices generate electromagnetic fields that sometimes have to be shielded in order not to affect neighboring electronic...

With an X-ray experiment at the European Synchrotron ESRF in Grenoble (France), Empa researchers were able to demonstrate how well their real-time acoustic monitoring of laser weld seams works. With almost 90 percent reliability, they detected the formation of unwanted pores that impair the quality of weld seams. Thanks to a special evaluation method based on artificial intelligence (AI), the detection process is completed in just 70 milliseconds.
Laser welding is a process suitable for joining metals and thermoplastics. It has become particularly well established in highly automated production, for...
