Active Corrosion Protection of Sintered AA7075 Aluminum Alloy via Mn Powder Addition

Advanced Engineering Materials, EarlyView.
AA7075 containing Mn‐rich particles is fabricated via spark plasma sintering using AA7075 and Mn powders. Corrosion resistance is evaluated through dip‐and‐dry tests using 0.1 M NaCl (pH 6.0), and mass loss decreases with increasing Mn addition. Mn‐rich particles function as a source of Mn ions, and formation of Mn‐accumulation films on Cu‐containing ...

ACT and district pumped hydro energy storage (PHES) atlas

, 2017
The ACT has relatively few potential sites for pumped hydro energy storage (PHES) sites due to the large fraction of the territory's mountains that is occupied by Namadgi National Park.

All‐in‐One Analog AI Hardware: On‐Chip Training and Inference with Conductive‐Metal‐Oxide/HfOx ReRAM Devices

Advanced Functional Materials, EarlyView.
An all‐in‐one analog AI accelerator is presented, enabling on‐chip training, weight retention, and long‐term inference acceleration. It leverages a BEOL‐integrated CMO/HfOx ReRAM array with low‐voltage operation (<1.5 V), multi‐bit capability over 32 states, low programming noise (10 nS), and near‐ideal weight transfer.

Technological developments for pumped-hydro energy storage [PDF]

, 2014
Today, everything seems to indicate that pumped hydro energy storage (PHES) is experiencing a second, or even third, youth (Fayolle and Lafon, 2008). Main drivers of such reemergence are mostly related with concerns on climate change and depletion of ...

Transient Simulation of Underground Pumped Storage Hydropower Plants Operating in Pumping Mode [PDF]

, 2020
The increasing penetration of variable renewable energies (VRE) in the European electricity mix requires flexible energy storage systems (ESS), such as pumped storage hydropower (PSH). Disused mining voids from deep closed mines may be used as subsurface

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Influence of pumped-storage operation on reservoir sedimentation [PDF]

In Europe, renewable energy sources are rapidly growing but are often linked to a highly volatile production, as for solar and wind energy. Pumped-storage plants have become very important since they can ensure grid stability and safe power supply at any

Energy storage in the UK electrical network : estimation of the scale and review of technology options

, 2010
This paper aims to clarify the difference between stores of energy in the form of non-rechargeable stores of energy such as fossil-fuels, and the storage of electricity by devices that are rechargeable.

Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer

Advanced Functional Materials, EarlyView.
Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...
