Moisture Harvesting by the Structure Regulation of Hygroscopic Hydrogel for Energy and Water Sustainability

open access: yesAdvanced Electronic Materials, EarlyView.
Hygroscopic hydrogels are capable of utilizing the moisture from air, which can transfer the gaseous water to liquid by a surface phase transition. Taking advantage of this water, sustainable water production, thermal management, and electricity generation can be realized.

Ultra‐thin ISFET‐based sensing systems

open access: yesElectrochemical Science Advances, Volume 2, Issue 6, December 2022., 2022
Abstract The ion‐sensitive field effect transistors (ISFETs), proposed little over 50 years ago, today make the most promising devices for lab‐on‐a‐chip, implantable, and point‐of‐care (POC) diagnostics. Their compatibility with CMOS (Complementary Metal Oxide Semiconductor) technology and the low cost through mass production have been the driving ...

Effects of the Operating Point of Photovoltaic Strings on Sizing of DC‐ and AC‐Connected Energy Storage Systems for Power Smoothing

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
This study is based on measured current–voltage curves of a 23 module photovoltaic (PV) string. The results of the study show that, in practice, following the maximum power point (MPP) closest to the nominal MPP voltage instead of the global MPP has no major effect on sizing of energy storage systems for power smoothing of PV strings. Photovoltaic (PV)
