Biomimetic Self‐Reconfigurable Soft Gripper for Cross‐Scale, Multi‐Particle, and High‐Load Multifunctional Manipulation

open access: yesAdvanced Science, EarlyView.
A fully soft, self‐reconfigurable gripper inspired by rapeseed flowers is monolithically 3D‐printed and electronics‐free, switching between diagonal and parallel finger arrangements. Establishing a self‐reconfigurable grasping paradigm, the gripper enables diverse manipulation tasks, including rotating bulbs, picking fruits, grasping cross‐scale ...

Chemically Gradient Ordered Nanodomains Enable Large Tensile Ductility in Gigapascal Lightweight Refractory High‐Entropy Alloys

open access: yesAdvanced Science, EarlyView.
A high‐strength lightweight refractory high‐entropy alloy achieves extraordinary ductility owing to the introduction of coherent chemically gradient ordered nanodomains (CGONs). The CGONs not only serve as effective barriers to dislocation motion (strengthening) but also significantly promote dislocation nucleation and multiplication (ductilizing) upon

Separation of microalgae suspension using rotating-disk dynamic microfilter

open access: yes, 2013
碩士本研究以旋轉盤薄膜微過濾進行微藻懸浮液之分離,提升微藻之採收與分離效率。利用旋轉盤造成之高剪切力降低濾餅之生成與過濾分離。以實驗與理論分析並行,探討旋轉盤轉速、進料速度與透膜壓差對過濾濾速、結垢阻力、濾餅性質與微藻粒徑大小之影響。 由實驗結果發現,對微藻粒子之阻擋率可達99.9 %,主要阻力來源為微藻形成之濾餅,而此濾餅具高壓縮性,壓縮係數為0.66。而增加進料速度與旋轉盤轉速,皆可提升膜面剪切力,掃除膜面濾餅與降低濾餅層厚度;故以低透膜壓差與高膜面剪切力之操作條件,即可得到最高的擬穩態濾速 ...

Nanoscale Optical Inhomogeneities From Compositional Segregation Within Individual GaN‐on‐Si Quantum Wells

open access: yesAdvanced Science, EarlyView.
This work visualizes local variations in luminescence and relates them to nanoscale chemical inhomogeneities in single InxGa1−xN quantum wells. We demonstrate that the elemental segregation is only inherent to quantum wells with high indium content. Density functional theory shows this to be the result of strain‐induced phase stabilization, explaining ...
