The influence of varying the manganese (Mn) contents high-strength copper-containing hull steel on its microstructural evolution and mechanical properties was investigated. With increasing Mn content from 2 to 5%, tensile strength increased by ~100 MPa, while elongation remained at ~23.5%, indicating good plasticity. However, 2Mn sample had 128 J higher low-temperature (−84 °C) impact work than 5Mn sample. microstructures different steels were composed fresh martensite (FM), ferrite/tempered...
Low carbon medium manganese steel with chromium and molybdenum addition (4MnCM), alongside a control group without these additions (4Mn), was developed. The quenching (860 °C) tempering (620 heat treatment process applied to both groups. influence of Cr Mo on the microstructure evolution mechanical properties examined. findings revealed that, low−temperature impact energy values (KV2) 4MnCM at −60 −84 °C were enhanced by 104 107 J, in comparison 4Mn. yield tensile strength saw an increase...
Volatile organic compounds (VOCs) emission on the working face of a large sanitary landfill in northern China was characterized one-year long sampling campaign. A total 67 VOCs with average annual concentration 2903.01 μg/m3 were detected. Ethanol dominant species detected VOCs, accounting for 76.4% - 82.3% volatile (TVOCs) concentration. showed seasonal variation as highest summer and lowest appeared winter. Furthermore, 50 identified non-carcinogenic chemicals 21 them carcinogenic...
Acid hydrothermal treatment of biowaste is beneficial for producing hydrochar and solution (HS) while alkaline condition fit hydrochar-derived humic acid (HA) production. Herein, HS was recycled as a solvent production used to prepare HA. Lower acidity (pH>1) led decrease in HHA yield (65.0 wt% 20.2 wt%). Sufficient (pH 0) the not only improved from 29.6 33.1 but also maintained HA at high level (68.2 71.2 wt%), ascribing adequate hydrolysis polymerization large number soluble chemicals into...

Volatile organic compounds (VOCs) emission on the working face of a large sanitary landfill in northern China was characterized one-year long sampling campaign. A total 67 VOCs with average annual concentration 2903.01 μg/m3 were detected where oxygenated most significant contributors samples. In particular, ethanol dominant species VOCs, accounting for 76.4% - 82.3% volatile (TVOCs) concentration. showed seasonal variation as highest summer, followed by spring and autumn, lowest appeared...
The humification behavior of lignocellulosic components (i.e., cellulose, hemicellulose and lignin) under acid-alkali two-step hydrothermal treatment was investigated with particular interest revealing the contribution single as well their interaction to humic acid (HHA). Lignin its rich aromatic structures, had highest HHA (51.8 1.0 wt%), while cellulose only contributed 8.8 1.6 wt% 20.1 4.4 yields, respectively. conversion pathway these toward indicated that hydrochar (HC) rather than...
