Ultra‐Sensitive Amperometric Detection of Ciprofloxacin in Environmental and Biological Matrices Using an ITO Modified With Tungsten Trioxide‐Based Nanocomposite

Electrochemical Science Advances, Volume 6, Issue 4, August 2026.
ABSTRACT Although significant progress has been achieved in the electrochemical sensing of ciprofloxacin (CIP), there remains a critical need for highly sensitive and reliable platforms capable of rapid charge transfer and accurate detection at trace levels in complex environmental and biological matrices.

Revealing the Roles of Electrolyte Concentration on Transition Metal Dissolution and Reaction Pathway of Anion Adsorption Pseudocapacitance

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Conventional lithium‐ion battery cathodes predominantly rely on reversible lithium intercalation in bulk, which inevitably induces phase transitions, transition metal migration, and voltage decay. Electrolytic anion adsorption pseudocapacitance provides a chance for bypassing these issues via a surface‐dominated reaction, especially in ...

Evaluating the Combined Effects of Elevated [CO2] and Accelerated NPQ Relaxation on Yield, Physiology and Transcription in Soybean

Plant, Cell &Environment, Volume 49, Issue 8, Page 6169-6187, August 2026.
ABSTRACT Improving photosynthesis is proposed as a means of enhancing crop productivity. To assess whether simultaneous increases in light use‐efficiency and carbon assimilation are additive, we investigated the impact of elevated CO2 on the performance of a transgenic soybean line engineered for faster relaxation of photoprotection by overexpression ...

Spherulite in the modern aragonitic travertine stromatolite has a calcite core with exopolymers

Sedimentology, Volume 73, Issue 5, Page 1421-1434, August 2026.
ABSTRACT Spherulites are spherical to ellipsoidal particles formed by various crystalline substances and can be abiotically synthesised in the laboratory. Among various spherulite types, spherulites composed of calcium carbonate are also found in various natural environments, but their abiotic or biotic origins are still controversial.
