Wetlands and Ecosystem Services

open access: yesEcology, Economy and Society – The INSEE Journal, 2023
Wetland paddy agro-ecosystems are recognized as important human-made wetland systems. Realizing that paddy lands are important ecological systems, the state of Kerala in southern India passed an act in 2008 preventing their conversion to other uses. The

Perspective on Aqueous Batteries: Historical Milestones and Modern Revival

open access: yesAdvanced Materials, EarlyView.
This review retraces the development of aqueous batteries from classical Zn‐MnO2 chemistry to modern Zn and Ni systems, correlating voltage, capacity, and electrolyte formulation with practical performance. By mapping historical success and failure onto current and future research directions, it identifies guiding principles that steer the design of ...

How plant composition in margins influences the assemblage of pests and predators and its effect on biocontrol in melon fields

open access: yesScientific Reports
Many agricultural landscapes offer few resources for maintaining natural enemy populations and floral plantings have frequently been adopted to enhance biological pest control in crops. However, restored margins may harbour both pests and natural enemies.

3D Printing of Highly Electrically Conductive Zinc for Sustainable Electronics Applications

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
A 3D printable zinc ink system with active zinc particles in a shellac matrix is demonstrated. The results show high conductivity, stable performance of printed structures under varying humidity conditions, and promising application in disposable water‐activated batteries. This technology combining digital material assembly, reliable operation, and non‐

Temperature‐Dependent Zinc Oxide Cathodoluminescence: Toward Compact Wavelength‐Tunable Solid‐State Photoionization Sources

open access: yesAdvanced Optical Materials, EarlyView.
A proof‐of‐concept of a thermally‐tunable cathodoluminescence‐based light source is demonstrated using a wide‐bandgap z‐cut ZnO crystal as anode, resulting in the ultraviolet (UV) emission peak shifting from 398 nm to ~409 nm (3.115‐3.032 eV). Our results establish the feasibility of a compact, field‐deployable UV source with potential for gas sensing ...
