Rare Metals, EarlyView.ABSTRACT Fluxgate sensors with Co‐rich amorphous microwires, widely used for their low noise in magnetic field measurements, encounter significant challenges in high‐temperature environments such as well drilling and geological exploration. Prolonged thermal aging degrades the performance of Co‐rich amorphous microwires, resulting in increased noise ...

Rare Metals, EarlyView.ABSTRACT Reliable operation of high‐performance magnetostrictive devices, composed of the giant magnetostrictive material (GMM), that is, the TbDyFe alloy, critically depends on an optimally tailored bias magnetic field. Sufficient intensity and uniformity are essential to induce the ideal initial strain in the GMM, enabling peak reciprocating output ...

Analysis on amide synthase and methyltransferase in biosynthesis of streptovaricin from the strain NRRL 2494 [PDF]
, 2015 曲张链菌素（streptovaricin）是由壮观链霉菌（Streptomycesspectabilis）NRRL2494产生的安莎类抗生素，与抗结核药物利福霉素具有相似的化学结构骨架，具有抗菌及免疫抑制等多种生物活性。本论文在对NRRL2494菌株基因组测序的基础上，获得曲张链菌素生物合成基因簇，并通过构建稳定的遗传操作体系，研究其生物合成途径中重要基因的功能，为利用组合生物学手段获得成药性好的曲张链菌素类化合物奠定基础。 本论文首次分析了NRRL2494菌株的基因组全长17.5MB序列 ...
