The paper examined the strength of rotationally welded joints between untreated beech dowels and samples thermally modified unmodified oak wood (used as substrates). results were compared with control group where glued using PVAc (polyvinyl acetate) glue for same types samples. Maximum dowel pull-out force was significantly higher connection to in both groups - treated wood. Welded joint group,...
Valuable chemical by-products can increase the economic viability of renewable transportation fuel facilities while increasing the sustainability of the chemical and associated industries. A study was performed to demonstrate that commercial quality chemical products could be produced using the non-catalytic cracking of crop oils. Using this decomposition technique generates a significant conce...
Arylalkynes can be converted into α-diketones with the use of a copper catalyst, and also be transformed into vinyl acetates under metal-free conditions, both in the presence of PhI(OAc)2 as an oxidant at room temperature. A series of substituted α-diketones were prepared in moderate to good yields. A variety of vinyl halides could be regio- and stereo-selectively synthesized under mild conditi...
