Stretching the Printability Metric in Direct‐Ink Writing with Highly Extensible Yield‐Stress Fluids
This study introduces “drawability” as a new metric for assessing printability in direct‐ink writing, focusing on gap‐spanning performance and speed robustness. By designing yield‐stress fluids with high extensibility, we demonstrate that extensional strain‐to‐break significantly enhances printability.

Laser‐Induced Graphene from Waste Almond Shells
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Traditionally, it is well known that the lowest‐order and the pole‐order (2pth‐order) radial forces play a leading role in the vibration response of fractional‐slot concentrated‐winding (FSCW) permanent magnet synchronous machines (PMSMs).

Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Slight Truncation Changes in Iron Oxide Nanocubes Strongly Affect Their Magnetic Properties
Subtle variations in nanoparticle morphology can lead to significant changes in functional properties. An automated shape‐fitting method captures minor differences in corner truncation between iron oxide nanocubes of similar sizes synthesized under identical conditions, revealing pronounced disparities in their magnetic and hyperthermia behavior ...

Ferroelectricity in Antiferromagnetic Wurtzite Nitrides
We establish MnSiN2${\rm MnSiN}_2$ and MnGeN2${\rm MnGeN}_2$ as aristotypes of a new multiferroic wurtzite family that simultaneously exhibits ferroelectricity and antiferromagnetism with altermagnetic spin splitting. By strategically substituting alkaline‐earth metals, we predict new materials with coexisting switchable polarization, spin texture, and

博士本論文主要目的為建立12/8極磁阻馬達之徑向力控制法則,且將所提出之法則應用於降低馬達震動與建立自軸承控制系統。透過有限元素分析軟體分析並建立馬達之數學模式,其中馬達定子與轉子凸極間之吸引力模式為轉子角度與激磁電流之函數,並且在模式中考慮互感之影響。分析此吸引力可分解出馬達之轉矩與徑向力,最後得到轉矩與徑向力模式。 本論文提出三種徑向力控制法則,研究最初首先提出利用具有相移之單相弦波激磁法則控制磁阻馬達之轉矩及徑向力,之後再提出兩相弦波激磁法則用以提昇單相弦波激磁法則徑向力之操作能力。另外 ...
