Influence of the heat treatment on corrosion characteristics of the Superston alloy
PublikacjaW artykule przedstawiono wpływ hartowania i odpuszczania na twardość i właściwości korozyjne stopu Superston, stosowanego na śruby okrętowe. Stwierdzono, iż hartowanie z temperatury 900 st.C i odpuszczanie w temperaturze 550 st.C znacząco podwyższa odporność na korozję stopu Superston w 3% roztworze NaCl w porownaniu ze stanem odlanym.

Integrating conventional nitrogen removal with anammox in wastewater treatment systems: Microbial metabolism, sustainability and challenges
PublikacjaThe various forms of nitrogen (N), including ammonium (NH4+), nitrite (NO2−), and nitrate (NO3−), present in wastewaters can create critical biotic stress and can lead to hazardous phenomena that cause imbalances in biological diversity. Thus, biological nitrogen removal (BNR) from wastewaters is considered to be imperatively urgent. Therefore, anammox-based systems, i.e. partial nitrification and anaerobic ammonium oxidation (PN/anammox)...
