In the present paper, the dislocation-precipitate interaction in the Inconel 718 superalloy is studied by means of molecular dynamics simulation. The atomistic model composed of the ellipsoidal Ni3Nb precipitate (γ″ phase) and the Ni matrix is con

Abstract The past decade has witnessed the significant efforts in novel material discovery in the use of data-driven techniques, in particular, machine learning (ML). However, since it needs to consider the precursors, experimental conditions, and av

A facile, one-pot two-step synthesis of 7-methylene-1,5-piperazine-fused 1,2,3-triazole derivatives has been developed. The protocol employs an N-allylation of N-propargylated amines with 2,3-dibromopropene in the presence of K2CO3 in DMSO and a CuI-

A new method for Cd-rich annealing of mercury cadmium telluride (MCT) was developed based on the observation that the deposition of Cd onto MCT by vacuum evaporation became self-limiting whenever the substrate temperature was above 70°C regardless o

The high-operating-temperature (HOT) midwave infrared (MWIR) n-on-p detector has been pursued using the high-density vertically integrated photodiode (HDVIP®) architecture. In this device, arsenic-doped HgCdTe grown by liquid-phase epitaxy (LPE) is

Electron injection avalanche photodiodes in short-wave infrared (SWIR) to long-wave infrared (LWIR) HgCdTe show gain and excess noise properties indicative of a single ionizing carrier gain process. The result is an electron avalanche photodiode (EAP
