, 2000 用ＲＡＰＤ技术对稀有Ｊｕ鲫近交１０代及３个野生群体的遗传多样性和群体间差异进行了研究。无论从多态位点的比例，个体间的共带率还是多样性指数来看，近交１０代的遗传多样性极低。在２２６个ＲＡＰＤ位点中，野生群体有近半数的位点是多态的，Ｓｈａｎｎｏｎ多样性指数在０．２９１１－０．３２３５间，表明自群本保持了较丰富遗传多样性。近交１０代与野生群体间遗传差异十分明显。野生群体间在１１ ...

Uncovering Cu Involved Nanophase Structures and Transformation in a Novel 7075B Aluminum Alloy
Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT In this study, aberration‐corrected transmission electron microscopy combined with first‐principles calculations was employed to systematically investigate the Cu‐involved crystal structures and evolution mechanisms of nanoprecipitates in a novel 7075B Al alloy. Firstly, an atomic model of the early‐stage GP‐ηp structure together with specific

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Currently, the photocatalytic performance of ZnO has been severely limited by its weak light response ability and sluggish charge carrier dynamics, which considerably hinder its extensive application in photocatalytic fields. Herein, through anchoring the synthesized K6PMo11FeO40·nH2O (PMo11Fe) onto ZnO nanosheets, a novel S‐scheme ...

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT The escalating severity of global environmental pollution necessitates the development of sustainable and efficient adsorption materials. Nanocellulose (NC), sourced from the most abundant natural polymer on earth, has shown great potential in this field due to its renewability, biodegradability, and exceptional nanoscale properties.

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Lignin hydrogenolysis is a promising route to separable aromatic monomers, yet practical upgrading is still hindered by macromolecular mass‐transfer limitations and the aggregation/deactivation of metal sites. Herein, we propose a “dual‐confinement” strategy to construct ultrafine Ru nanoclusters supported on lignin‐based N‐doped hierarchical ...
