Sodium‐Based Battery Component Design: Imitating Lithium or Forging New Paths?

open access: yesSmall, EarlyView.
This Perspective elucidates the decisive yet underexplored impact of cation chemistry, Na+ vs. Li+ charge carriers, on the design, selection, and formulation of their corresponding battery systems, addressing common misconceptions and the pitfalls of overreliance on Li+ design principles. Leveraging the unique characteristics of Na+, it comprehensively

Near‐Atomic Investigation on the Elemental Redistribution During Coprecipitation of Nano‐Sized Kappa‐Type and B2 Precipitates in an Al‐Alloyed Lightweight Steel

open access: yessteel research international, EarlyView.
Elemental redistribution during coprecipitation of kappa (κ)‐type and B2 precipitates in an Al‐alloyed lightweight steel is revealed by atom probe tomography (APT) and density functional theory (DFT). Fe and Ni redistribution promotes the evolution of B2 phase from NiAl‐type toward FeAl‐type and improves the stability of κ and B2 phases during ...

Damage Investigation of the Preform Operations for the Production of Rings for Ring Rolling

open access: yessteel research international, EarlyView.
Void evolution during the preforming operations of two industrial ring rolling process routes is investigated by combining metallographic characterization with a two‐scale finite element simulation approach. The results reveal that, despite differing initial void conditions, the preforming operations can be designed to effectively influence void ...

An efficiency enhanced cluster expanding block algorithm for copy-move forgery detection

open access: yes, 2016
碩士本論文提出一個以多重分類為基準的複製移動竄改偵測技術,在多重分類的方法流程中,首先對影像所分割出來的區塊進行兩種不同的特徵提取,接著以兩種特徵值對區塊分別進行分類,並且將每個類別集合成大類以增加區塊相似度的範圍,透過多重分類篩選相似的區塊後,取在兩種分類中皆為同類別的區塊進行比對,可以有效的降低區塊間比對次數,使得在比對階段效率大幅提升,且同時過濾不相似區塊。比對階段時,利用由小到大的區塊擴張比對方式,可以在大量的比對動作中,有效減少其計算量,最後將偵測出區塊以記綠水平垂直距離的方式進行匹配 ...

Concrete in architecture: Redefining form, space, function, and insights from bibliometric analysis

open access: yesStructural Concrete, EarlyView.
Abstract Concrete has become a cornerstone in architectural and engineering innovation, as it seamlessly integrates structural performance with artistic expression. Its evolution from ancient opus caementicium to contemporary ultra‐high‐performance concrete illustrates its adaptability to the change in technological, environmental, and design paradigms.
