Groove is made of metal, as a transition from the industrial floors to various wallsGroove is made of metal (1), characterized as a modular element in the required lengths, on the bottom (9) and (11) is screwed.
Currently, atom transfer radical polymerization (ATRP), as a transition metal-catalyzed CRP, is one of the effective procedures. The benefits of ATRP include wide applications in the preparation of well-defined polymers with sophisticated architecture, predicted molecular weight, and narrow polydispersity...

The invention relates to new triaza transition metal complexes and their use as polymerization catalysts. They have the formula (1): LnMXm-n, wherein each L is independently a ligand which is multidentate by adjacent cooordinating atoms, M is the central atom which is a metal selected from ...
The aim of the invention is to suggest a use of a catalyst for eliminating tar substances from raw syngases, said use being characterized by greater economy. Said aim is achieved by using transition metal oxides as transition metal oxide catalysts for selectively oxygenating tar substances in syng...
·H2O [3MeO-H2salbn =N,N′-bis(3-methoxysalicylidene)butane-1,4-diamine] and are best represented as the intimate ion-paired adducts [SnR2]2+·[NiL(NCS)2]2–[L = Schiff-base ligand; R = Me or Bun] in each of which the tin atom sits in the plane of, and is held by ...
Moreover, it is preferable to find cocatalysts made of non-noble metals because of their availability and cost. Hematite (α-Fe2O3,α is omitted henceforth) is a transition metal oxide that has been widely used and studied as photocatalyst and cocatalyst in water splitting and other chemical ...
