Investigating the Origin of Topological‐Hall‐Like Resistivity in Zn‐Doped Mn2Sb Ferrimagnet
ABSTRACT Skyrmions and other chiral spin textures have been extensively studied as potential building blocks for novel spintronic devices. Hall‐resistivity anomalies that deviate from magnetization scaling, known as the topological Hall effect, have been widely employed as evidence for the presence of chiral spin textures in magnetic materials. However,

目的本试验探讨如何建立结核菌生物被膜体外模型。方法选取生长良好的非耐药结核菌在罗氏固体培养基中复苏,在7H9OADC培养基中重新培养1周,使其活力相同,配置苏通培养基分别在烧瓶及孔板中培养结核菌观察生物膜的生长情况。结果 36株结核菌在孔板中培养时使用封口膜的全部培养出生物膜,而未使用封口膜的均培养失败。烧瓶中培养:在培养3周时需要松开瓶盖,否则生物膜生长不良。时间:培养2周时可看到有生物膜出现,5周时生物膜培养成熟。结论结核菌有生物被膜,通过体外培养可以成功获得。

ABSTRACT Diffusion bonding (DB) of near‐α titanium alloys requires high temperatures, which can cause grain coarsening, structural deformations, and degradation of the workpiece's mechanical characteristics. In this study, thermal hydrogen processing (THP) was applied to Ti65, combined with selective magnetron sputtering of a Ti‐Al thin film to promote

Unlocking grass leaf development: foundations for tunable cereal design
Summary The grass leaf plays a critical role in global food security, generating the carbon stores in cereal grains, which provide > 50% of global calories. As the global population grows, there is an urgent need to increase food production using fewer resources and to develop more resilient agricultural systems to withstand variable climate conditions
