Photon Recycling–Driven Photodetection Enhancement in Ni(AcO)2–MAPbBr3 Nanocomposite Waveguides

open access: yesNanophotonics, Volume 15, Issue 13, 13 July 2026.
Photon recycling is demonstrated as an effective mechanism to enhance perovskite photodetector performance. A Ni(AcO)2/MAPbBr3 nanocomposite waveguide enables long‐range propagation and reabsorption of photoluminescence photons, increasing photocurrent by ∼60%. Under pulsed excitation, reabsorption of amplified spontaneous emission further enhances the

Droplet Electricity Generators With Maximized Energy Collection Zone Enabled by Aloe‐Inspired Midrib and Cuticle

open access: yesAdvanced Materials, Volume 38, Issue 39, 13 July 2026.
An Aloe‐pinspired droplet electricity generator (A‐DEG) overcomes the limited energy collection zone of conventional DEGs by guiding impact droplets through a channeling midrib and artificial cuticle. The channeling midrib induces uni‐directional droplet spreading, while the artificial cuticle on the midrib further reinforces this behavior through its ...

Time Series Modelling of Temperature Distributions in Proton Exchange Membrane Fuel Cells

open access: yesAdvanced Sustainable Systems, Volume 10, Issue 7, July 2026.
A long short‐term memory framework is developed for predictive thermal monitoring of proton exchange membrane fuel cells using operating conditions and current distribution data. The model accurately predicts spatial temperature distributions with limited training data, enabling computationally efficient diagnostics and hotspot identification for ...

Modelling the Demand for Indonesia’s Foreign Reserves

open access: yesECONOMICS
The foreign reserves sufficiency is important to maintain macroeconomic stability. The main objective of this paper is to model the behaviour of the central bank in accumulating the foreign reserves in the case of Indonesia. Unlike the previous empirical

Ag‐Promoted Na Retention for Synergistic Defect Passivation in Kesterite Solar Cells

open access: yesAdvanced Energy and Sustainability Research, Volume 7, Issue 7, July 2026.
A synergistic Ag–Na codoping strategy in solution‐processed kesterite solar cells enables simultaneous lattice ordering and defect passivation. Ag promotes grain growth and Na retention, while Na enhances carrier concentration and reduces recombination.

Synthesizing polyethersulphone membranes with hybrid iron/nickel nanoparticles for dyes removal: An efficient biogenesis approach

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 7, Page 3593-3617, July 2026.
Abstract Industrial wastewater contamination by azo dyes poses a significant environmental challenge. This study reports the green synthesis of bimetallic iron/nickel (Fe/Ni) nanoparticles using moringa leaf extract, which acted as both a reducing and capping agent, and their incorporation into polyethersulphone (PES) membranes to produce eco‐friendly ...

Selective Optical Properties of Cement for Enhanced Radiative Cooling and Energy‐Efficient Construction Materials

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.
Cement phases are good materials for radiative cooling thanks to the selective emissivity in IR ATW. Cement powders have high reflectance of solar radiation which reduces the thermal losses. The onset of the absorption curves is defined by bound excitons. Sulfates have higher radiated powers and reflectance than calcium silicates.

Econometric Modelling of the Impact of Metrology on the Economy in Poland

open access: yesFolia Oeconomica Stetinensia
Studying the impact of metrology on the economy is a complicated matter. This is due to the specific nature of both metrology and the economy. There is no established method for determining the impact of metrology on the economy.
