Advanced Engineering Materials, EarlyView.A combined experimental–computational framework identifies energy‐dependent laser absorptivity for NiTi in laser powder‐bed fusion, applicable to conduction and transition modes. Single‐track experiments and thermofluid smoothed particle hydrodynamics simulations are coupled through inverse analysis of melt pool geometry.

Advanced Engineering Materials, EarlyView.Binder‐free laser powder bed fusion of 8YSZ with a femtosecond laser is used to map process windows linking scan strategy, heat accumulation, and grain growth. Time‐resolved thermography and simulations reveal thermal regimes that enable continuous, vitrified, and fine‐grained 8YSZ surface layers without absorptive additives and demonstrate ...

A Novel Approach to Estimate the Transition Temperature via Dynamic Nanoindentation
Advanced Engineering Materials, EarlyView.A new dynamic nanoindentation‐based method was developed that uses the stiffness ratio as an indicator of the elastic–plastic deformation contributions at different temperatures. The approach successfully identified transition temperatures in ferritic steel and distinguished them from continuously ductile austenitic steel.

Design of a Time-To-Digital Converter with Resolution of Sub-Pico Second
, 2012 計畫編號：NSC100-2221-E032-066 研究期間：20110801~20120731 研究經費：463,000隨著半導體製程之進步，電晶體的操作速度越來越快。相反的，電晶體的操作電壓卻 越來越低，使得以往在電壓域(Voltage Domain)設計電路變得越來越困難。尤其是在 類比數位轉換器的設計上，要達到高解析度變得十分困難。反之，由於電晶體的操作 速度越來越快，因此在時間域(Time domain)上處理訊號可達到的解析度越來越高。因 此運用時間數位轉換器處理訊號可達具有高解析度、省電 ...
