Implantable Ionic Memristors Based on Natural Polymer Heterojunctions

open access: yesAdvanced Functional Materials, EarlyView.
We report an implantable natural polymer‐based ionic memristor composed of hyaluronic acid, chitosan, and PDMS. The device achieved 98.94% accuracy in MNIST classification while reducing training time by 36.8% compared with a conventional artificial neural network (ANN).

Ionic Precursors Transformed Into Vinyl Acetate Synthesis Catalyst via Reaction‐Driven Restructuring

open access: yesAdvanced Functional Materials, EarlyView.
This work demonstrates that a simple physical mixture of Pd and Au ionic precursors, KOAc promoter, and SiO2 support can transform into a highly active vinyl acetate synthesis catalyst through reaction‐driven restructuring. The results highlight reaction‐induced restructuring as an innovative and sustainable catalyst design strategy.

Application of a two dimensional model to predict the effects of the curtain method on algal blooming in reservoirs [PDF]

open access: yes, 1997
As one of the ways of reducing algal blooming in T-Dam reservoir, two vertical curtains, having depths to cover the epilimnion thickness, are installed across the reservoir in order to curtail the nutrient supply from nutrient-rich inflow to the ...

Understory bamboo removal impacts on woody seedling regeneration in forest ecosystems: a meta-analysis

open access: yesEcological Processes
Background Tree seedling regeneration in forests is often hindered by the competitive influence of dense understory bamboo competition. While localized studies have investigated the ecological effects of understory bamboo removal on tree seedlings, a ...

Monolithic Oxidation Enables Ultrathin Vertically Graded Tantalum Oxide for Low‐Voltage, Low‐Variability Memristive Switching

open access: yesAdvanced Functional Materials, EarlyView.
Monolithic UV‐ozone oxidation of Ta forms an ultrathin Ta2O5/TaOx bilayer enabling resistive switching with a vertical defect gradient. A stoichiometric surface layer over an oxygen‐deficient sublayer promotes localized filament nucleation near the top interface, enabling low‐voltage operation, and reduced cycle‐to‐cycle variability.

Functionalizing Micro‐to‐Mesoscopic Electrode Architectures for Regulating Electron Transfer Behaviors in Electrocatalysis

open access: yesAdvanced Functional Materials, EarlyView.
A systematic review is conducted to assess the influence of electrode architecture across micro‐ to mesoscopic length scales on electron‐transfer pathways in electrocatalysis. We discuss the structure‐activity relationships in electrocatalytic applications, including resource recovery and environmental remediation, and provide cost‐effective, efficient

Reservoir Life Expectancy in Relation to Climate and Land-Use Changes: Case Study of the Mangla Reservoir in Pakistan [PDF]

open access: yes, 2013
The dams and reservoirs are one of the largest sources to store surface water. The escalating water crisis in the new millennium has made it very important to preserve available water and in turn to preserve the storage capacity of dams and reservoirs ...

Underground Oxygen Deficiency Alters the Spatial Distribution Pattern of Rooting in Alternanthera philoxeroides

open access: yesPlants
Terrestrial and amphibious plants frequently encounter severe oxygen deficiency in waterlogged environments. While the impacts of nutrient and water availability on root development are well documented, how underground oxygen status drives the spatial ...

Assessment of water quality in Yapialtin Dam Lake (Sivas, Turkey) during dry and rainy seasons using various parameters and water quality indices [PDF]

open access: yesJournal of the Serbian Chemical Society
There are many dam lakes in the Şarkışla district of Sivas, where agricultural activities are intense. Yapıaltın Dam Lake, which constitutes our study area, is one of them. The research was conducted at three stations in Yapıaltın Dam Lake during the dry
