A Homoleptic Copper(I) Acetylene Complex

Chemistry – A European Journal, EarlyView.
Ligand substitution of weakly coordinated N2 in [(N2)Cu{Al(ORF)4}] (RF = C(CF3)3) leads to the homoleptic acetylene complex [Cu(C2H2)3]+[Al(ORF)4]−, which was characterized by single crystal x‐ray diffraction, NMR, and Raman spectroscopy, as well as by extensive quantum chemical calculations. ABSTRACT We report the synthesis and characterization of the

Improving Welding Behavior of ETPU Bead Foams by Surface Modification with Plasticizers

Journal of Polymer Science, EarlyView.
Tributyl citrate (TBC) and stearic acid (SA) modify ETPU beads through different diffusion mechanisms. TBC diffuses the bead structure directly after coating, whereas SA remains on the surface until melting and subsequent diffusion during heating. The resulting plasticization improves bead fusion, allowing RF processing at reduced temperature and ...

Additive Manufacturing of Hot‐Work Tool Steel by In Situ Alloying Using Laser Powder Bed Fusion and Directed Energy Deposition—Strategies to Improve Chemical Homogeneity

steel research international, EarlyView.
To support future alloy development a powder mixture is processed by laser additive manufacturing. The powder mixture containing Mo‐ and W‐rich tracers is processed by powder bed fusion using single and double laser exposure and by directed energy deposition which provides drastically enlarged melt pools.
