Synergistic Effects of Ruthenium and Zinc Active Sites Fine Tune the Electronic Structures of Augmented Electrocatalysis

open access: yesAdvanced Functional Materials, EarlyView.
This study presents an electronic fine‐tuning (EFT) strategy to optimize the electronic structures of Ru species and single‐atom Zn sites by the virtue of layered nanosheets, significantly enhancing ORR and HER activities. Spectroscopic analysis and theoretical calculations uncover that this EFT effect breaks the ORR scaling limitation and positions ...

Electricity Generation From Ambient Water Evaporation in the Absence of Sunlight via PVA‐Based Porous Hydrogels

open access: yesAdvanced Functional Materials, EarlyView.
In this article, a water‐evaporation driven energy harvester is devised that works even in the absence of sunlight. This is achieved by combining PVA hydrogel with thermoelectrics (TEG) to directly capture energy from water evaporation. Under mild conditions (RH 40%, T of 26 °C, and 2.8 m s−1 wind), 1.71 mW (1.02 W m−2) power can be generated, >3 fold ...

Hydrophobic Deep Eutectic Solvent (DES) Design Enables Optimally Hydrated DES‐in‐Water Electrolytes for High‐Performance Bromine Redox‐Enhanced Energy Storage Systems

open access: yesAdvanced Functional Materials, EarlyView.
Faradaic charging with bromine redox chemistry shows promise for energy storage, yet its efficient use in aqueous electrolytes is hindered by water decomposition and polybromides' cross‐diffusion, leading to suboptimal cell performance. This study introduces a tetrabutylammonium bromide‐based hydrated deep eutectic electrolyte with optimized water ...

Upscaling Lithium-ion Batteries for Small Scale Applications [PDF]

open access: yesE3S Web of Conferences
Electricity is a necessity, and batteries are a common way to store and use energy. Different types of batteries such as lithium-ion are used in devices such as laptops and power banks. However, when the battery management system fails, the whole battery

Molehills into mountains: Transitional pressures from household PV-battery adoption under flat retail and feed-in tariffs [PDF]

open access: yesarXiv, 2020
With Australia's significant capacity of household PV, decreasing battery costs may lead to widespread use of household PV-battery systems. As the adoption of these systems are heavily influenced by retail tariffs, this paper analyses the effects of flat retail tariffs with households free to invest in PV battery systems.

The Economics of Battery Storage for Residential Solar Customers in Southern California [PDF]

open access: yes, 2021
Battery storage coupled with solar panels became a consideration after the original net metering program in California (NEM 1.0) ended and gave way to the current net metering program (NEM 2.0).

Interfacial Interaction‐Mediated Regulation of Metal Oxidation States for Enhanced CO2 Reduction

open access: yesAdvanced Functional Materials, EarlyView.
A hybrid strategy is employed to optimize bismuth–oxygen interactions, precisely regulating interfacial bismuth–oxygen bonds during topochemical synthesis. This leads to vanadium oxynitride‐bismuth catalyst exhibiting high Faradaic efficiency and durability for formate production, attributed to enhanced reaction thermodynamics and kinetics.
