Invention: Filaments made of a thermoreversible thermoset based on Diels Alder cycloadductsare used in 3D filament printing to create 3D artifacts that will irreversibly cure via reaction ofreactive diene or dienophile components. This allows filaments to be made and a thermoset tobe formed in the f.....

Zeolites have found wide application in catalysis and separation processes due to their tunable pore structure and active sites, and they show remarkable stability in commercial use. Recently, ultra-thin two-dimensional (2D) zeolite nanosheets have been synthesized from zeolite precursors. These ult.....

A new hybrid, 3D, Metal, Prototyping Device combines welding technology, instead of laser sintering of a metal powder, with a subtractive/machining process (Computer Numerical Controlled Machining - CNC) to create metal parts with unmatched complexity, precision, and quality. The device has a low, i.....

Introduction The Wood Plastic Composite (WPC) industry is moving towards using petroleum-free components for WPC blends, while attempting to retain or improve performance of their products. Wood plastic composite products have strength and stiffness properties that are somewhere between plastic and .....
