Long‐Lifespan Polyorganosiloxane‐Based Silicone Evaporator for High‐Efficiency Seawater Desalination

Advanced Science, EarlyView.
Conventional evaporators suffer from salt crystallization and degradation. We design a white polyorganosiloxane evaporator with a reflector, achieving 4.344 kg m−2 h−1 at 1 sun in 3.5 wt.% NaCl. It shows over 53‑day cycling stability and 197‑day seawater resistance.

Scaling of Planar Sodium‐Nickel Chloride Battery Cells to 90 cm2 Active Area

Batteries &Supercaps, Volume 8, Issue 3, March 2025.
Large planar Na β′′ alumina electrolytes are prepared by tape‐casting and die‐pressing. These ceramic electrolytes are used to prepare planar sodium‐nickel chloride cells with 90 cm2 active area, providing a high capacity of 7 Ah. Successful cell cycling is demonstrated at 300 °C at rates up to C/4 (20 mA cm−2) for a cumulative capacity of 3.6 Ah cm−2.

Carbon Dot Nano‐Spacers in Triazine Networks for Integrated Photothermal Seawater Desalination and H2O2 Production

Carbon Energy, EarlyView.
Cyanated carbon dots (CN‐CDs) are synthesized by the hydrothermal method with carboxymethyl cellulose and cyanobenzoic acid, and CD‐CTN is obtained in situ via cyclotrimerization of CN‐CDs. CD‐CTN possesses excellent photothermal catalytic H2O2 production in seawater, and desalted H2O2 could be obtained, which demonstrates the practical application for

Uniaxial compressive strength prediction and ratio parameter optimization of titanium tailings composite backfill materials using intelligent hybrid models

Deep Underground Science and Engineering, EarlyView.
Based on the 90 datasets, ERT and four optimization algorithms were used to build four hybrid models to predict the UCS of the backfill body. The SMA‐ERT model was the most effective model, and it can reliably guide the design of the backfill ratio parameters. Abstract This study analyzed the feasibility of using titanium (Ti) tailings as a backfilling
