Olefin (co) trimerization catalyst systems, their preparation, as well as olefin (co) trimerization and for the olefin oligomers (co) polymerization process using the catalyst system This invention regards the polymer of the olefin oligomer which generates by the trimer conversion reaction of the ...
Inventing a new process For years, researchers have attempted to develop mechanically interlocked molecules with polymers but found it near impossible to coax polymers to form mechanical bonds. To overcome this challenge, Dichtel’s team took a whole new approach. They started with X-shaped monomers...
Metal production is anenergy-intensive processthatgenerates significant greenhouse gas emissions, while metal mines are often associated with thedestruction of biodiverse environments. PPSU also requires significant energy use and is produced from non-renewable petrochemical feedstocks, which...
Macroautophagy generates energy and amino acids during nutrient deprivation. Because of its nature, it has long been thought an unselective process for bulk degradation of long-lived proteins and organelles. However, recent studies revealed significant selectivity in autophagic degradation of various cellul...
PROBLEM TO BE SOLVED: To provide a polyoxymethylene resin material for cutting, extremely improved so that a molded product therefrom scarcely generates a white spot in the central area of its cross-section when subjected to extrusion molding, while keeping various excellent characteristics inherent in...
Laser-induced ablation of polymers using a patterned dopant generated from a leuco-dye precursor via flood exposure: A "portable conformable mask" approach to laser ablation of PMMA at 351 nm A two-stage laser ablation process is described, which initially generates a laser-light absorbing image ...
The functional part is at least partially formed from an at least partially laser-permeable material. An at least partially laser-impermeable barrier layer is arranged such that after the laser light has penetrated the functional part, the laser light within the barrier layer generates heat by abs...
The process of the invention generates surfaces with self-cleaning properties by, prior to the thermal shaping, applying microparticles to the inner surfaces of the mold and then carrying out the molding process, in which the microparticles are pressed into and anchored into the surface of the ...
