From Single Atoms to Nanoparticles: Pathways Toward Efficient and Durable Pt/TiO2 Photocatalysts

open access: yesAdvanced Functional Materials, Volume 36, Issue 44, 1 June 2026.
Platinum single atoms on TiO2 nanosheets evolve into clusters and nanoparticles under ethanol photoreforming and thermal treatments. By controlling deposition and post‐treatments, particle size and location on specific facets are modulated. The study reveals how stability pathways determine efficiency, guiding the design of more durable photocatalysts.

Post‐Shaping Over‐Impregnation: A Facile Strategy for Pt‐KL Catalysts With Ultrahigh Metal Dispersion and Enhanced Aromatization Performance

open access: yesCarbon and Hydrogen, Volume 28, Issue 2, Page 196-208, June 2026.
A scalable post‐shaping strategy achieves precise Pt localization within KL zeolite, where optimized spatial distribution minimizes diffusion barriers to deliver superior n‐hexane aromatization activity, selectivity, and stability. ABSTRACT The precise localization of metal clusters within zeolite frameworks is critical for the aromatization catalysis.

Tuning the Geometric and Electronic Structures in PtMn/SiO2 Catalysts via Oxygen Plasma Treatment for Enhanced Propane Dehydrogenation

open access: yesCarbon and Hydrogen, Volume 28, Issue 2, Page 184-195, June 2026.
Oxygen plasma treatment promotes Pt dispersion, reducing the average Pt particle size of PtMn catalyst from 2.7 to 1.2 nm, and increases the electron cloud density of Pt. The optimized catalyst exhibits excellent mass‐normalized activity (171 molC3H8·gPt−1·h−1) and an ultralow deactivation rate constant, outperforming most reported Pt‐based catalysts ...

A coincidence‐based response matrix for correction of charge sharing spectral distortions in photon counting detectors

open access: yesMedical Physics, Volume 53, Issue 6, June 2026.
Abstract Background Charge sharing between pixels distorts the count and spectral information of X‐ray photon counting detectors. Compensation methods for charge sharing effects are required to exploit the full potentiality of these detectors in medical diagnosis.

Sustainable treatment of banana leaves for phytosanitary applications: impact, spreading, and impregnation of mineral oil

open access: yesPest Management Science, Volume 82, Issue 6, Page 5555-5566, June 2026.
Mineral oil droplets spread anisotropically, penetrate banana leaf tissues, and diffuse into the palisade parenchyma, revealing a delayed, Fickian mechanism that supports improved phytosanitary spray strategies. Abstract BACKGROUND Efficient application of phytosanitary sprays is essential for sustainable control of foliar fungal diseases such as Black
