Advanced Materials, EarlyView.Topological insulator–metamaterials integrated with electrically driven terahertz quantum cascade lasers enable parity‐dependent harmonic generation. Bulk‐dominated Bi2Se3 favors third‐harmonic emission at 9.96 THz, whereas topological‐surface‐state‐dominated Bi2Se3, Bi2Te3, and (Bi,Sb)2Te3 generate strong second harmonics near 6.5 THz.

Factors influencing snatch performance in elite weightlifters
In the snatch, an athlete's success is dictated by the mass they are able to lift and hold overhead in one smooth movement. Optimal technique during the pull has only been hypothesized from collected barbell trajectory and joint kinematic data of top ...

Evolution of OLED Lamination Technology With Development of Display Form Factors
Advanced Materials Technologies, EarlyView.This review evaluates the evolution of organic light‐emitting diode (OLED) lamination technologies alongside advancing display form factors. It contrasts optically clear adhesives and resins, highlighting uniformity control for rigid screens, bubble‐free optimization for bended architectures, and visible‐light curing for foldable layers.

Advanced Materials Technologies, EarlyView.Graphical abstract illustrating the fabrication of Ni–P–O–C porous carbon microlattice electrodes by DLP printing of Ni/P precursor‐containing resin followed by high‐temperature carbonization. The resulting conductive microlattice acts directly as the HER cathode in alkaline electrolyte, where in situ formed Ni–P–O–C interfaces provide active sites for

Kinematical and Kinetical Analyses on Hand Snatch and Jerk of EliteMale Weightlifters in Taiwan
, 2010 [[abstract]]本研究之目的在探討我國男子舉重選手實施抓舉與挺舉動作並以進行運動學及動因學予以比較與分析。茲因舉重比賽的舉法中，抓舉與挺舉的動作，技術與難度常為舉重選手比賽勝負的關鍵；若能針對抓舉與挺舉動作，技術與難度，以進行運動學及動因學加以比較與分析，將結果提供參賽選手參考，應可增加獲得獎牌機會。本研究是根據攝影機及測力板獲得五位優秀男子舉重選手的抓舉與挺舉在各階段過程中之差異，所獲得結論如下：踝關節、踝關節和髖關節之角度，經過三種不同試舉重量時，提鈴期與發力期，在抓舉角度是比挺舉角度大 ...

Acute Effects of the Power Snatch on Vertical Jump Performance
, 2017 PURPOSE: Very slight improvements in sport performance can mean the difference between a win and a loss. One of the most common assessments of lower limb performance is the vertical jump. This study examined the acute effects of the power snatch exercise
