The International Water Management Institute (IWMI) will hold a consultation workshop to co-design a roadmap for scaling circular solutions in Ghanaian agriculture.

• Event overview: IWMI will convene researchers, innovators, policymakers and investors to co-design a roadmap for scaling circular solutions that enhance agricultural productivity and resource efficiency; the process will also shape the CircularEconomy4Ghana Innovation Challenge and identify high-impact value chains.

  • Date & time: November 27, 2025, 00:00 UTC
  • Registration: Zoom registration at https://us02web.zoom.us/meeting/register/yqkbKVcbRQS8JlcTwQbGNg#/registration
  • Agenda/subject: co-design roadmap, align innovation, policy and investment, identify cocreation opportunities and priority value chains.

• Background & logistics: The workshop is presented on IWMI’s events page and includes calendar/ICS links (Google Calendar, iCal, Office 365, Outlook Live) for participants; the format and host platform include Zoom for registration and participation.

The U.S. Energy Information Administration reports that electricity generation from natural gas in California has decreased while solar generation has risen.

• EIA data (Jan–Aug 2025): total electricity generation 140.9 BkWh; solar (utility-scale) 40.3 BkWh (nearly double 22.0 BkWh in Jan–Aug 2020), solar generation +17% vs 2024 (+5.9 BkWh); natural gas supplied 45.5 BkWh (−18% vs 2020) and fell 9.5 BkWh (−17%) vs 2024, the largest year‑over‑year drop in 2025.
• CAISO and grid details: midday solar capacity (May–June) increased from 10.2 GW (2020) to 18.8 GW (2025); evening battery discharge rose from <1 GW (May–June 2022) to 4.9 GW (2025), displacing natural gas during 5:00–9:00 p.m.; note CAISO changed natural gas data methodology in Dec 2023, so pre‑Dec 2023 natural gas data are not comparable. Data sources: Electric Power Monthly and Hourly Electric Grid Monitor.

North University of China publishes a review on doping modification of Na3V2(PO4)3 (NVP) cathode materials.

• Main announcement: The review summarizes research on doping modification of NVP, covering single-element, binary, ternary, and multi-element doping, and discusses how doping at different chemical sites affects performance. Corresponding author: yjchen@nuc.edu.cn; affiliations include School of Materials Science and Engineering, North University of China and the Shanxi Key Laboratory of Efficient Hydrogen Storage & Production Technology and Application.
• Background and findings: The paper highlights synergistic effects, multi-electronic reactions, and high entropy effects as key benefits from doping regulation, and identifies low electrical and ionic conductivity as the primary limitation of NVP that doping aims to address.

Researchers report a facile two-step synthesis of Ir single atoms and sub-nanometer clusters anchored on nickel aerogels (Ir-SAs@Ni Aerogel) for alkaline water oxidation.

• Main result: The Ir-SAs@Ni Aerogel catalyst achieves 281 mV overpotential at 10 mA·cm-2, a Tafel slope of 64.36 mV·dec-1, and stability >66 h in 1.0 M KOH, significantly outperforming commercial IrO2. The synthesis uses EDTA as a molecular barrier to trap Ir3+ ions, followed by thermal annealing under Ar/H2 to stabilize isolated Ir atoms and sub-nm clusters on conductive Ni aerogels.
• Background and mechanisms: Characterization attributes performance to synergistic effects of Ir single atoms/clusters, strong electronic interaction with the Ni aerogel substrate, and a porous aerogel structure facilitating mass/charge transfer. DFT calculations confirm that introduced Ir single atoms lower key OER energy barriers and optimize adsorption energies of oxygen-containing intermediates.
