Rare Metals, EarlyView.ABSTRACT Nb‐Si‐based superalloys are considered as the most potential candidate materials for nickel‐based superalloys due to the lower density and higher using temperature. Here, a type of stable Nbss/γNb5Si3 bi‐phases structure with a coherent interface has been successfully designed. Additionally, the Nbss and γNb5Si3 phases showcase the orientation

Rare Metals, EarlyView.ABSTRACT Nanocomposite permanent magnets with reduced rare‐earth content represent a promising class of materials for next‐generation high‐performance applications. However, asynchronous precipitation of soft and hard magnetic phases often results in grain size mismatch and limited coercivity.

Temperature Distribution Analysis of Wood Cutting Tool with Differential Method [PDF]
, 1972 切削中の木材切削工具の温度分布を実測することには種々の困難があるので, 理論的に温度分布を求める一方法を示した。すなわちいくつかの仮定を置いて作った温度分布に関する微分方程式を差分方程式に変換し, それをし緩法によって近似的に解いた。その結果, たとえば切削速度が40m/secの時, 定常状態において刃先の温度は500 ...

Novel Non‐Equimolar High‐Entropy Zirconates With Superior Thermophysical Properties
Rare Metals, EarlyView.ABSTRACT Rare‐earth zirconates (RE2Zr2O7) are promising candidates for topcoat materials in thermal barrier coatings (TBCs). However, their practical application in TBCs is limited by poor fracture toughness and low thermal expansion coefficient (TEC).

Rare Metals, EarlyView.ABSTRACT Converting CO2 to CH4 under mild conditions is a promising strategy for solving environmental and energy problems, but also a challenge. In this work, the low‐temperature CO2 hydrogenation process over Ni/CeO2 catalysts was significantly accelerated by optimizing the H2 dissociation ability of Ni through the size effect, thus A‐Ni/CeO2 with an

線虫Caenorhabditis elegansの低温耐性における精子から神経へのフィードバック制御 [PDF]
, 2017 全ての生物にとって、環境温度は生存と繁殖に非常に重要な環境情報である。そのため、全ての生物には環境温度に適応するための生体メカニズムが存在する。動物の温度耐性メカニズムには多くの組織が関与するが、それらの組織間の相互作用による統合的な制御メカニズムは詳細がまだ明らかとなっていない。そこで、シンプルなモデル動物である線虫Caenorhabditis elegansの低温耐性現象をモデルとして、動物の温度耐性メカニズムの解明を目指した。線虫の低温耐性とは、20℃で飼育した個体は2 ...

Rare Metals, EarlyView.ABSTRACT Early detection of thermal runaway (TR) is essential for lithium‐ion battery (LIB) safety, as unchecked TR risks catastrophic failures in energy storage systems. Gas‐based sensing offers a faster and more direct approach by detecting decomposition products at the molecular level.
