free carbon–carbon bond-forming coupling between tosylhydrazones and boronic acids. This reaction is very general and functional-group tolerant. As the required tosylhydrazones are easily generated from carbonyl compounds, it can be seen as a reductive coupling of carbonyls, a process of high ...
This process obeys the Lindemann criterion13,17 of melting which requires large enough amplitude of ligand and metal node displacements to exchange with their nearest neighbors16,18. In this context, both the high coordination number (CN) and large porosity of metal nodes are detrimental to the ...
Finally, the colony-forming units (CFU) were counted after 24 h of incubation at 37 °C. 3. Results and Discussions Metal-free photocatalysts are of great interest for solar energy conversion due to their low cost of production. Herein, we prepared heterojunction composites between g-C3N4 ...
Due to efficiency and cost reduction requirements, numerical simulation has been applied to sheet metal-forming processes since the 1960s [1]. Currently, numerical simulations can accurately replicate the forming process due to the ability to process complex iterative calculus using material properties,...

idea. In simple terms, the process of metal forming requires a piece of metal to be mechanically deformed (as in pushed and squashed through a device or rollers to change its shape) but no elements are removed or cut off during the process nor does the weight of the metal change in any...

One of ElringKlinger AG's core competencies is the manufacture of metal sealing elements for the automotive industry. A stamping and bending process is used as the standard procedure. This is also state of the art in the production of ring gaskets, which
Traditional sheet metal forming is a capital- and time-intensive process that requires an expensive stamping press, which often costs about $1 million, as well as tools and dies that take months to produce. While similar processes such as hydroforming, fluid cell presses, and zinc low-cost die...
