Silver‐Alloyed Wide‐Bandgap (Ag,Cu)(In,Ga)S2 Thin‐Film Solar Cells With 15.5% Efficiency

open access: yesProgress in Photovoltaics: Research and Applications, Volume 34, Issue 7, Page 942-956, July 2026.
This study reports improvements in compositional homogeneity, microstructure, enhanced radiative recombination, and extended carrier lifetime of CIGS absorber via Ag incorporation. The optimal Ag‐alloyed CIGS solar cells achieve 15.5% PCE and 948 mV VOC, competing with the VOC of the Ag‐free reference sample from the same batch.

Multi‐Site Chelation Enabled by 3D‐Printed TiO2 Hydrogel Monoliths for Dynamic Ge(IV) Recovery in Fixed Beds

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Germanium is a critical dispersed metal, yet sustainable recovery from dilute solutions is limited by sorbents that are difficult to regenerate and operate in continuous mode. Here, we fabricate a regenerable 3D‐printed hydrogel monolith (3D‐ATO‐GS) by integrating hydroxyl‐rich amorphous TiO2 nanoparticles into an alginate/gelatin scaffold ...

Defining the geographical level of competition: a taxonomy of industry tradability

open access: yesEconomica, Volume 93, Issue 371, Page 962-991, July 2026.
Abstract The paper develops a taxonomy of industry tradability to define the geographical level at which competition takes place. First, it creates a novel dataset that combines production and international trade data for both goods and services industries, defined at a detailed (3‐digit) level of industry aggregation for 15 European countries.

Performance of the Direct Current Electric Potential Difference (DCEPD) Method for Crack Extension Measurement in Fracture Mechanics Specimens Exhibiting Split Delaminations

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 7, Page 2963-2980, July 2026.
ABSTRACT This work investigates the performance of the direct current electric potential difference (DCEPD) method for measuring crack extension ( ∆a) during fracture toughness tests of ductile steels exhibiting delaminations perpendicular to the main crack plane, known as splits.

Reduction of Oxide Inclusions During the High‐Frequency Welding of Steel via a Nonthermal Ar/H2 Plasma Jet

open access: yesAdvanced Engineering Materials, Volume 28, Issue 12, 17 June 2026.
High‐frequency (HF) welding of steel is limited by oxide inclusions that degrade weld quality. This study demonstrates, for the first time, the integration of a nonthermal Ar/H2 dielectric barrier discharge (DBD) plasma jet into HF welding. Local plasma treatment provides effective shielding and in‐situ oxide reduction, resulting in markedly fewer and ...

A Critical Appraisal of Pyrolysis Pretreatment in Lithium‐Ion Battery Recycling: From High‐Temperature Material Transformations to Environmental Impact

open access: yesChemSusChem, Volume 19, Issue 11, 15 June 2026.
Pyrolysis of different size fractions of waste lithium‐ion batteries reveals complex interaction among cathode materials, graphite, aluminum, and polymeric binders. Carbothermic and aluminothermic reduction pathways promote the formation of metallic species at moderate temperatures.
