Fabrication of wide-IF 200–300GHz superconductor–insulator–superconductor mixers with suspended metal beam leads formed on silicon-on-insulator
This article reports on a fabrication process that uses silicon-oninsulator (SOI) substrates and micromachining techniques to form wide-IF superconductor–insulator–superconductor (SIS) mixer devices that have suspended metal beam leads for rf grounding. Aside from a description of the fabrication process, electrical measurements of these Nb/Al–AlNₓ /Nb trilayer devices will also be presented.

Fabrication and characterization of inkjet-printed 2D perovskite optoelectronic devices
Article presents the large scale synthesis of solution-processed 2D (CH₃(CH₂)₃NH₃)₂(CH₃NH₃)ₙ − 1PbₙI₃ₙ + 1 (n = 2, 3, and 4) perovskites, a family of layered compounds with composition-tunable bandgap, where inkjet printing was used to fabricate heterostructure, flexible photodetector devices. The flexible, inkjet-printed perovskite 2D heterostructures have significant potential for optoelectronic devices, which can enable broad possibilities with compositional tunability and versatility of the organohalide perovskites.

3D-printed and injection molded polymer matrix composites with 2D layered materials
This article reports on a study where 2D TMDs (MoS₂ and WS₂) and the 3D allotrope of carbon and graphite were incorporated into acrylonitrile butadiene styrene (ABS) and polyethylene terephthalate glycol (PETG) matrices in order to form polymer matrix composites (PMCs). The multipronged analysis described in this study was motivated by the purpose to fuse together topics of low-cost, additive manufacturing with 2D layered materials, and studying their ensuing mechanical and tribological properties.

On Batch-Processing Based Coded Computing for Heterogeneous Distributed Computing Systems
This article focuses on practical computing systems with heterogeneous computing resources, and designs a novel CDC approach, called batch-processing based coded computing (BPCC), which exploits the fact that every computing node can obtain some coded results before it completes the whole task. The scheme demonstrates promising performance in terms of high computational efficiency and robustness to uncertain disturbances.
