Gongye shui chuli, 2021 研究了采用以聚氨酯海绵和沸石粉为单体制备的新型载体与普通聚氨酯海绵载体的MBBR体系的脱氮效果，并利用微电极技术对2种载体内部的DO和ORP分布特征进行了分析。结果表明，新型载体MBBR体系具有更高效的脱氮性能，TN去除率和同步硝化反硝化（SND）性能比聚氨酯海绵载体MBBR体系高约10%；新型载体内部的DO和ORP比聚氨酯海绵载体下降快，其内部具有更大范围的缺氧区域，从而有利于反硝化过程的发生，提高了体系的SND性能。

Taxonomic and functional diversity of urban bees of the world
Conservation Biology, EarlyView.Abstract Bees play a pivotal role in terrestrial environments. Urbanization can affect these organisms and the ecosystem services they provide. However, knowledge of the global diversity of urban bees is limited. Thus, we summarized data on urban bee species identities and occurrences; compared distributions of all bees with those found in urban ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT The deformation behavior of NiTiNb shape memory alloys is governed by microstructural heterogeneity, specifically the interconnected topology of the β‐Nb phase. The regulatory role of the eutectic structure in load partitioning and the evolution of deformation mechanisms, particularly in high‐Nb systems, has not been clearly understood.

Tracing change in the public perception of plants: insights from archives and social media in China
PLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1853-1871, September 2026.As urbanization accelerates, historic gardens serve as vital cultural treasures that offer spiritual and cultural support to the public. This study proposes an innovative approach that merges historical records from the Qing Dynasty with contemporary social media data to explore changes in public perceptions of these gardens.
