FEM thermal analysis of Cu/diamond/Cu and diamond/SiC heat spreaders

AIP Advances, 2017
The effects of thermal stress resulting from thermal cooling in copper/diamond/copper heat spreader is investigated using finite element method. A similar model of diamond/SiC heat spreader is compared without addition of interlayer.

A Diamond Temperature Sensor Based on the Energy Level Shift of Nitrogen-Vacancy Color Centers

Nanomaterials, 2019
The nitrogen-vacancy (NV) color center in chemical vapor deposition (CVD) diamond has been widely investigated in quantum information and quantum biosensors due to its excellent photon emission stability and long spin coherence time.

Gallium Microalloying in Bi–Sn Solders: Interfacial Phase Formation, Wettability, and Long‐Term Shear Reliability Under Isothermal Aging

Advanced Engineering Materials, EarlyView.
Gallium microalloying redirects interfacial reactions in low‐temperature Bi–Sn solders from Cu–Sn toward Cu–Ga intermetallic formation. The resulting Cu–Ga layer suppresses intermetallic growth during thermal aging, alters fracture pathways, and improves interfacial stability.

Proposal of a Double Diamond Model of Social Response

Review of General Psychology, 2013
Models of social response concern the identification and delineation of possible responses to social pressure. Previous efforts toward a unified model have been limited to conceptualizations that define conformity and its alternatives based on discrete categories (e.g., Montgomery, 1992 ; Nail et al., 2000 ). Social response in many settings, however,

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.

Axial collapse behavior of stainless steel circular tubes with thin walls in diamond mode

Scientific Reports
As a commonly used axial crushing energy-absorbing component, the theoretical model of the diamond mode of thin-walled circular tubes is less successful than the ring mode.

Effect of Cu and CuP Additions on the Microstructure and Nanoindentation‐Based Fracture Behavior of CoNiAlSi Ferromagnetic Shape Memory Alloys

Advanced Engineering Materials, EarlyView.
Cu and combined Cu–P microalloying refine the microstructure and enhance the nanoindentation‐derived fracture resistance of CoNiAlSi ferromagnetic shape memory alloys without suppressing the martensitic transformation. Comparative SEM, DSC, and nanoindentation results reveal that the CuP‐containing alloy provides the most balanced response, achieving ...
