AkzoNobel Industrial Chemicals will apply a unique caustic soda evaporation system to its new membrane electrolysis plant at the Industry Park Höchst in Frankfurt, Germany. The system will enable 20% energy savings and will be supplied by Alfa Laval. The evaporation system which will concentrate cau more
Different methods of vacuum regulation in rotary evaporators are compared according to their benefit for the user. Essential criteria of such analyses are process time, rate of solvent recovery, ease of handling, and flexibility. Speed controlled diaphragm pumps with automatic regulation feature obvious advantages and an extremely long performance life of wear parts more
In modern chemical and pharmaceutical lab buildings vacuum supply has become a standard for each work station, just as water or gas supply. Therefore vacuum supply solutions are considered at earliest stage for new laboratory buildings and are fully integrated in the planning and layouting procedure in many cases. Demands for vacuum vary over a wide range of applications – e.g. evaporation, distillation, vacuum drying, or simply filtration and aspiration. All of these can be covered well by Chemistry Diaphragm Pumps more
The production of SERS-active substrate with uniform, sensitivity, reproducibility and durability still remains an important issue. Here, we report a fabricating strategy for large-area Ag-decorated TiO2 nanograss SERS-active substrate by a simple solvothermal approach combined with Ag evaporation. more
The contact line dynamics during the evaporation of nano-droplets sessile on textured solid substrates is investigated using molecular dynamics method. Our simulations reproduce the nanoscale physical phenomena such as the constant contact angle (CCA) and constant contact radius (CCR) evaporation mo more
The presence of organic surfactants in atmospheric aerosol may lead to a depression of cloud droplet growth and evaporation rates affecting the radiative properties and lifetime of clouds. Both the magnitude and mechanism of this effect, however, remain poorly constrained. We have used Raman thermom more
Dimethyl formamide, as a solvent with low evaporation rate, is comprehensively used in the production of chemical fiber, plastics, and pharmaceuticals, etc. In the 1990s, with the fast development of DMF’s downstream industries, polyurethane industry and acrylon industry, DMF production in China bec more
