主要研究磷（P）和硼（B）对Nb—Ti无间隙原子钢（iF钢）动态再结晶及组织的影响。为实现该目的，采用4种不同P和B的加入量进行Nb＋Ti—iF钢的研究。热压缩实验进行动态再结晶行为研究，采用拉伸试验机进行热轧iF钢机械性能研究，电子背散射衍射技术（EBsD）研究微观组织织构。研究表明在900—1000℃时B元素强烈推迟iF钢动态再结晶。然而，P元素在1100℃时也不会延迟动态再结晶。P对动态再结晶的影响远小于B对动态再结晶的影响。EBsD分析表明P和B都会细化铁素体晶粒并且形成许多大角度晶界。含有0．1％P和0．001％B的iF钢铁素体晶粒细化程度是不含P和B的46．4％。

irisin is a myokine that is generated by cleavage of the membrane protein fibronectin type Ⅲ domain-containing protein 5(FNDC5) in response to physical exercise. studies reveal that irisin/FNDC5 has neuroprotective functions against Alzheimer's disease, the most common form of dementia in the elderly, by improving cognitive function and reducing amyloid-β and tau pathologies as well as neuroinflammation in cell culture or animal models of Alzheimer's disease. Although current and ongoing studies on irisin/FNDC5 show promising results, further mechanistic studies are required to clarify its potential as a meaningful therapeutic target for alleviating Alzheimer's disease. We recently found that irisin treatment reduces amyloid-β pathology by increasing the activity/levels of amyloid-β-degrading enzyme neprilysin secreted from astrocytes. Herein, we present an overview of irisin/FNDC5's protective roles and mechanisms against Alzheimer's disease.

Quasi-isotropic laminates have isotropic elastic properties in all in-plane directions. Therefore, this kind of laminate is widely used for structural elements. The simplest stacking sequence of quasi-isotropic laminates is [0/-60/60]s. When the direction of applied axial load to [0/-60/60]s laminate is inclined at a 30-degree angle, we have the other quasi-isotropic laminate [30/-30/90]s under axial load. The failure mechanisms of these two laminates are, however, entirely different from each other because these two laminates have different distribution of the interlaminar stresses. it was confirmed by tensile fatigue tests that the [0/-60/60]s laminate does not show any visible fatigue damage, but the [30/-30/90]s laminate develops edge-delamination during cyclic loading. The analytical results were in good agreement with the experimental results.
