A review of energy harvesting using piezoelectric materials: state-of-the-art a decade later (2008–2018)

open access: yesSmart materials and structures (Print), 2019
Energy harvesting technologies have been explored by researchers for more than two decades as an alternative to conventional power sources (e.g. batteries) for small-sized and low-power electronic devices. The limited life-time and necessity for periodic

Exploiting radiative cooling for uninterrupted 24-hour water harvesting from the atmosphere

open access: yesScience Advances, 2021
This work presents a continuously operating (24-hour), energy-neutral, radiative cooling system, to harvest water from the air. Atmospheric water vapor is ubiquitous and represents a promising alternative to address global clean water scarcity ...

Comparison of energy-wood and pulpwood thinning systems in young birch stands [PDF]

open access: yes, 2011
In early thinnings, a profitable alternative to pulpwood could be to harvest whole trees as energy-wood. In theoretical analyses, we compared the extractible volumes of energy-wood and pulpwood, and their respective gross values in differently aged ...

Interdigitated Horizontal Electrodes for Organic Solar Cells

open access: yesIEEE Access, 2018
We first introduce a new electrode structure for organic solar cells (OSCs), the so-called interdigitated horizontal electrode (IHE), in which an electron-collecting electrode and a hole-collecting electrode are horizontally separated.
