Ultra‐Fast Non‐Volatile Resistive Switching Devices with Over 512 Distinct and Stable Levels for Memory and Neuromorphic Computing

open access: yesAdvanced Functional Materials, EarlyView.
A materials and device design concept that comprises a self‐assembled ultra‐thin epitaxial ion‐transporting layer, an amorphous oxide overcoat oxygen‐blocking layer, and a partial filament formed during an electroforming step is proposed for low‐current multilevel resistive switching devices.

Biodiversity is a cauliflower under the sunlight [PDF]

open access: yes, 2012
For a long time ecologists have questioned the variations of biodiversity across the latitudinal gradient. Recently it has emerged that the changes in [beta]-diversity are caused simply by changes in the sizes of species pools.

Photochemical Effects of Sunlight

open access: yesBiophysical Journal, 1972
The importance of sunlight in bringing about not only photosynthesis in plants, but also other photochemical effects, is reviewed. More effort should be devoted to photochemical storage of the sun's energy without the living plant. There is no theoretical reason to believe that such reactions are impossible.

Ionic Liquid‐Based Reversible Metal Electrodeposition for Adaptive Radiative Thermoregulation Under Extreme Environments

open access: yesAdvanced Functional Materials, EarlyView.
A wideband tunable electrochromic device with dynamic thermal emissivity control is demonstrated. The system enables adaptive heat regulation via electrochemically modulated silver deposition, achieving efficient cooling and heating states. The flexible design ensures mechanical robustness under bending conditions, making it promising for portable and ...

The Photocatalytic, Thermal Degradation Kinetics and Lifetime Prediction of Some Commercial Reactive Dyes [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 2017
The photocatalytic degradation of the commercial reactive Black5 (RB5), Blue19 (RB19), Green19 (RG19), Red120 (RR120), and Yellow81 (RY81) in aqueous solution and sunlight were examined in the presence of Fe2O3 and the mixture Fe2O3/H2O2 as catalysts ...

High‐Performance Low‐Emissivity Paints Enabled by N‐Doped Poly(benzodifurandione) (n‐PBDF) for Energy‐Efficient Buildings

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces a scalable and colored low‐emissivity (low‐e) paint achieved by spraying an ultrathin n‐doped poly(benzodifurandione) (n‐PBDF) coating onto various colored substrates. The low‐e paint enhances thermal regulation by reducing mid‐infrared thermal emissivity to 0.19, thereby stabilizing indoor temperatures across diverse climates ...
