Grazing plays a crucial role in regulating SOC storage in grassland ecosystems. However, the mechanistic understanding of how grazing influences the SOC dynamic still needs to be improved. We investigated how grazing-induced microenvironment changes influence the microbial assimilation of plant litter C and SOC formation from decomposed litter C in a multi-year field experiment, where grazing was simulated with mowing, dung and urine return, and trampling. We incubated 13C labeled litter in PVC collars to trace the microbial assimilation of litter C and the fate of litter C in the SOC after decomposition. While the grazing treatments changed soil properties marginally, mowing decreased above-ground plant biomass, litter mass, plant height, and plant cover (-12 \% to -79 \%). Accordingly, mowing treatment increased the exposure of litter to UV radiation (+38 \%) and therefore facilitated the microbial assimilation of litter C (+20 \%) and the SOC formation (+15 \%). Trampling treatment promoted the transformation of litter C to SOC pools by mixing litter and soil (+34 \%). Dung and urea return treatment did not affect SOC formation due to a marginal change in available nitrogen. Collectively, our results suggest that grazing facilitates litter-derived SOC formation by regulating microbial involvement through changes in the microenvironment. Our study indicates that grazing promotes SOC formation from plant litter, which maintains SOC storage in grasslands. Accurate quantification of the contribution of plant C input to SOC pools in different grasslands under various utilization is the next step to better predict SOC dynamics.}, language = {en} } @misc{LiuDongZhangetal., author = {Liu, Wen-Cai and Dong, Jie and Zhang, Ping and Zheng, Xing-Wei and Ding, Wen-Jiang and Li, De-Hui and Korsunsky, Alexander M.}, title = {Smooth and notched fatigue performance of aging treated and shot peened ZK60 magnesium alloy}, series = {Journal of materials research}, volume = {25}, journal = {Journal of materials research}, number = {7}, issn = {2044-5326}, pages = {1375 -- 1387}, language = {en} } @inproceedings{DreibatiZhangWolfetal., author = {Dreibati, Ossama and Zhang, Wei and Wolf, Matthias and Ossenbrink, Ralf and Michailov, Vesselin}, title = {Thermo-mechanical properties of refractory ceramic for the numerical simulation of their thermo-shock behaviour}, language = {en} } @misc{WangZhangLiangetal., author = {Wang, Pu and Zhang, Wei and Liang, Owen and Pantoja, Marcos and Katzer, Jens and Schroeder, Thomas and Xie, Ya-Hong}, title = {Giant enhancement and anomalous behavior of Graphene Raman spectra on plasmonic nanostructures}, series = {ACS Nano}, volume = {6}, journal = {ACS Nano}, number = {7}, issn = {1936-086X}, pages = {6244 -- 6249}, language = {en} } @misc{ZhangDoynovWolfetal., author = {Zhang, Wei and Doynov, Nikolay and Wolf, Matthias and Dreibati, Ossama and Ossenbrink, Ralf and Michailov, Vesselin}, title = {Investigation of the Thermal Shock Behavior of Ceramic Using a Combination of Experimental Testing and FE-Simulation Methods}, series = {Advanced engineering materials}, volume = {15}, journal = {Advanced engineering materials}, number = {6}, issn = {1527-2648}, doi = {10.1002/adem.201200241}, pages = {480 -- 484}, abstract = {Thermal shock behavior of ceramics plays a decisive role in their broad industrial applications. For enhanced understanding of damage and failure mechanism under thermal shock loading, in the present work, a combination of experimental testing and numerical simulation methods has been used. The thermal shock behavior of the alumina (99.7\%) disk samples has been investigated by using a plasma test stand: the bottom of the ceramic disks were locally heated in the center by plasma beam; during the heat treatment the temperature distribution at the top of the sample was recorded with a thermographic system. To characterize the thermal shock resistance, a thermomechanical simulation was subsequently carried out. It calculates the temperature and stress distribution within the ceramic disks. The calculated critical thermal tension stresses are reported, which led to the failure of the ceramic disks under thermal shock loading. The effect of the sample thickness on the temperature and stress distribution is presented. Compared with the experimental results the simulated results show excellent agreement. As conclusion, it is possible to determine the thermal shock behavior of ceramic materials by the combination of experimental testing and numerical simulation.}, language = {en} } @misc{WangLiangZhangetal., author = {Wang, P. and Liang, O. and Zhang, Wei and Schroeder, Thomas and Xie, Y.
