Production of ultra-steep dichroic filters with broad band …

The feasibility of using direct broad band optical monitoring control in the fabrication of the ultra-steep dichroic filters based on resonant structures is investigated. Using computational manufacturing and deposition experiments, the role of the errors self-compensation effect is clarified by comparing the results of direct broad band optical monitoring and time monitoring. …

Production of ultra-high temperature carbide (Ta,Zr)C by …

The combustion temperatures and rates of mechanically activated (MA) Ta–Zr–C mixtures depending on the initial temperature T 0 are determined. The self-heating phenomenon is observed in argon atmosphere at T 0 >380 K due to oxidation of the surface of zirconium particles by adsorbed oxygen. Zirconium oxide is formed in the combustion zone at the initial …

Production of ultra-high-molecular-weight poly-γ-glutamic …

Poly-γ-glutamic acid (γ-PGA) is a microbial-derived polymer with molecular weight (Mw) from 10 4 to 10 7 Da, and the high-Mw (> 7.0 × 10 5 Da) or ultra-high-Mw (> 5.0 × 10 6 Da) γ-PGA has important application value as a tissue engineering material, as a flocculant, and as a heavy metal remover. Therefore, how to produce these high-Mw γ-PGAs with low cost and high efficiency …
