Summary: This study aims to develop a single solar still that is directly connected with a solar parabolic trough and does not utilize any heat exchanger. Through field experiments, it was found that the overall water productivity of the modified solar still increased by 177% compared to the conventional still. The study also proposed future investigation of a step-shaped conical unit for the same device, which appears more promising and easier to handle, install, and maintain.

Summary: In this study, a novel self-powered and high-efficiency negative air ion (NAI) generator in pipeline is proposed for air purification in the ventilation system. The self-power is achieved by utilizing a novel device of wind energy triboelectric nano-generator (WE-TENG) to efficiently harvest wind energy in the pipeline. The self-powered NAI generator efficiently generates a high volume of NAIs in the pipeline, harnessing the air-purifying properties of NAIs, thereby making a significant impact on the practical application of self-powered indoor air purification systems based on TENG.

Summary: This article investigates the task scheduling problem in solar-powered Internet of Things (IoT) networks with wireless energy sharing capabilities. The objective is to minimize the completion time of all tasks. A novel mixed-integer linear program (MILP) is proposed to schedule tasks and determine whether devices share harvested energy through radio frequency (RF) in each time slot. The MILP considers the relationship between the energy level of devices across time slots and the dependency of tasks. Additionally, a heuristic algorithm called MinTime-ES is proposed for large scale networks, achieving significant reductions in task completion time compared to algorithms without energy sharing.

Summary: Smart transportation should tackle utility waste, traffic congestion, and air pollution in future smart cities with minimal human intervention. In order to achieve sustainable operation, solar-harvesting charging stations and rooftops are utilized to power electric autonomous vehicles (AVs) through design. The framework optimizes the locations of charging stations based on solar energy distribution and proposes a stochastic algorithm to adapt to changes in distribution. Route planning is also optimized to balance energy consumption and harvesting, and a utility optimization algorithm for shared electric AVs is proposed. Extensive simulations show significant improvements compared to other strategies.
