Supercritical Fluid‐Based Synthesis of Nanomaterials for Energy Storage Applications: A Pathway Toward High‐Entropy Oxides

Battery Energy, Volume 5, Issue 6, November 2026.
Supercritical fluid (SCF) synthesis offers tunable solvent properties (T > Tc, P > Pc), enabling rapid nucleation, uniform composition, and controlled growth of nanomaterials. This approach facilitates homogeneous multication mixing and entropy stabilization, promoting single‐phase high‐entropy oxides (HEOs) for advanced electrochemical applications ...

Bifacial (Ag,Cu)(In,Ga)Se2 Mini‐Modules With Transparent ITiO Back Contacts: Performance Analysis and Effects of RbF Treatment

Solar RRL, Volume 10, Issue 19, 15 October 2026.
Bifacial ACIGS mini‐module prototypes with In2O3:Ti back contacts are fabricated and analyzed. Efficiencies of 13.5% and 10.3% are achieved under front and rear illumination, respectively. High bifaciality factors of up to 76% are enabled by the excellent transparency and conductivity of the thermally stable In2O3:Ti film.

Interface Engineering Toward High‐Efficiency CIAS Thin‐Film Solar Cells Using a Cadmium‐Free CuAlSe2 Buffer Layer: A SCAPS‐1D Investigation

physica status solidi (a), Volume 223, Issue 19, 6 October 2026.
Cadmium‐free CuAlSe2 emerges as a promising buffer layer for Cu(In,Al)Se2 (CIAS) thin‐film solar cells. An optimal buffer thickness of 0.01 µm and a conduction band offset of −0.25 eV, combined with a NiO hole transport layer, increase the simulated efficiency from 16.9% to 26.39%.

Study of the Electrochemical Passive-Active Transition of Chalcopyrite in Acidic Solution

International Journal of Electrochemical Science, 2016
The electrochemical behaviors of chalcopyrite in 1.0 M H2SO4 were studied by potentiodynamic polarization. The experimental results revealed that chalcopyrite has four different potential ranges: passive for OCP up to 500 mV; trans-passive dissolution ...

Composition Control in CuInZnS2 Nanocrystals by Cation Exchange and Their Phase Transfer

ChemNanoMat, Volume 12, Issue 10, October 2026.
This work elucidates the composition‐defining parameters for CuInZnS2 (CIZS) nanocrystals (NCs) prepared by a cation exchange reaction. Investigations focus on their cation shares and size, which influence both the absorbance and the bandgap. Furthermore, a novel ligand exchange route from 1‐dodecanthiol to 11‐mercaptoundecanoic acid is shown, thereby ...

Geochemical Modeling of Black Smoker Fluid Formation at the TAG Hydrothermal Vent Field

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Seafloor hydrothermal systems facilitate energy transport and chemical exchange between oceanic crust and seawater. The chemistry of hydrothermal fluids is attained through reactions with basaltic rock during fluid recharge, but the spatio‐temporal scales of fluid‐rock‐interaction at depth are difficult to constrain.

The influence of NaCl on xanthate adsorption on chalcopyrite surface and chalcopyrite flotation

Minerals Engineering
Due to freshwater scarcity, mineral flotation plants have been using alternative water resources including seawater together with water recycling, resulting in the accumulation of salts in process water. However, how salts affect the adsorption of xanthates on the surfaces of sulphide minerals and subsequent sulphide mineral flotation is unclear.

An Analytical Model for the Spectral Induced Polarization of Metallic Particles Including Stern‐Layer Polarization

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract Spectral induced polarization (SIP) is sensitive to metallic grains in geologic materials. Classical diffuse‐layer theory predicts a weaker dependence of relaxation time on electrolyte conductivity than is commonly measured, whereas surface‐capacitance models can reproduce the stronger dependence but do not explicitly resolve the diffuse layer

A novel molybdenite depressant for efficient selective flotation separation of chalcopyrite and molybdenite

International Journal of Mining Science and Technology
A novel small molecule depressant (M-DEP) was used to separate chalcopyrite and molybdenite via flotation. The results showed that M-DEP had an excellent selective depression on molybdenite, while had little effect on the flotation of chalcopyrite.

Correlative optical, electron, and electrochemical microscopy assessment of localised sulphide reactivity in concrete aggregates

Journal of Microscopy, Volume 304, Issue 1, Page 65-74, October 2026.
Abstract Iron‐sulphide‐bearing aggregates can compromise concrete durability when reactive sulphide phases, particularly pyrrhotite (Fe1–xS), oxidise and contribute to internal sulphate attack, cracking, and premature deterioration. Existing aggregate assessment methods, including bulk sulphur measurements, petrographic examination, oxygen consumption ...
