Gongye shui chuli, 2023 漆酶（LAC）能够有效催化氧化废水中多种难降解的有机污染物，但其游离态不够稳定，且难以回收再利用。采用动态晶化法合成了一种由MWW结构纳米片交错共生而成的分级孔空心分子筛微球（HZM），并将其用于LAC的固定化。结果表明，通过戊二醛（GA）交联法可将LAC固定于氨基功能化的HZM上，固载量可达198.6 mg/g，酶活性回收率约为52.4%；与游离态LAC相比，固定化LAC对酸度和温度敏感性降低，储藏和操作稳定性有明显提升；固定化酶循环使用8次后，仍可保留初始活性的50%以上 ...

Gongye shui chuli, 2011 采用SA—CaCl2包埋法和PVA—H3BO3交联法固定化白腐真菌,并进行固定化组分优化,并对两种方法所形成的固定化小球性能进行了比较。结果显示:固定化组分优化后,两种方法均能得到较好的固定化效果。由性能比较结果可知:SA、PVA固定化小球均有较好的细胞增殖能力和良好的传质性,SA固定化小球机械强度较低,剧烈搅动易破裂,只适宜保存在潮湿环境中,而PVA固定化小球强度较高,原料价格较低,固定化小球在空气或水中均适宜保存。

There Is Always a Bigger Fish. Determinants of Power Perceptions in Swiss Biodiversity Policy
Policy Studies Journal, EarlyView.ABSTRACT The Advocacy Coalition Framework (ACF) views power as crucial in policy processes, but the nature of coalition power, its determinants, and how to empirically measure it remain understudied. In this article, we use a mixed method approach and social network analysis to explore power relationships in the biodiversity policy subsystem in ...

From the Margins: Potential Coalitions in Centralized, High‐Capacity States
Policy Studies Journal, Volume 54, Issue 4, November 2026.ABSTRACT The early stages of coalition formation remain an understudied area, particularly in centralized, high‐capacity political systems. Examining actor dynamics at this formative stage can reveal how coalitions form and how limited pluralism constrains their development.

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT To improve the strength–toughness balance of IN718, and alleviate the brittleness commonly associated with refractory high‐entropy alloys, this study proposes a novel strategy to fabricate defect‐free IN718/WMoTaNb heterogeneous multiprincipal element alloy coatings via laser‐directed energy deposition.

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.
