Summary: This article investigates a UAV-assisted wireless powered Internet-of-Things system, formulating an optimization problem to minimize the average Age of Information (AoI) of data collected from all ground sensor nodes. By decomposing the problem into two subproblems and using dynamic programming and ant colony heuristic algorithms, optimal solutions are found for reducing the average AoI of the system. The results demonstrate that the flying altitude of the UAV and the size of collected data at each ground sensor node have a linear impact on the average AoI.

Summary: This paper investigates the influence of nanopillars on the thermal boundary resistance of AlN/diamond interfaces using Non-equilibrium Molecular Dynamics method. The optimal AlN/diamond interface with nanopillar structures can reduce the thermal boundary resistance by 28%. The analysis of vibrational density of states reveals that the enhancement of AlN intermediate frequency phonons and the shift of diamond VDOS towards lower frequency contribute to the optimization of interfacial thermal transport.

Summary: This article introduces the use of strain-induced polarization to enhance the performance of piezoelectric solar cells. Nonuniform strain can effectively increase the piezoelectric polarization, improving the power-conversion efficiency (PCE) of piezoelectric solar cells. By strain-induced polarization, the PCEs of solar cells based on 2D WS2 and MoS2 are boosted to 48.1% and 42.8%, respectively. Strain-induced polarization not only increases the built-in field, but also simplifies bandgap gradients through inexpensive strain regulation. In this article, a tandem and parallel piezo-phototronic solar cell with single-type 2D piezoelectric semiconductor materials is proposed, providing a novel way to develop an ultrahigh efficiency 2D material solar cell.
