Alkoxy Side Chain Engineering in Metal‐Free Covalent Organic Frameworks for Efficient Oxygen Reduction

open access: yesAdvanced Materials, EarlyView.
This study explores how alkoxy side chains influence COF properties to enhance oxygen reduction reaction (ORR) performance. Incorporating varying alkoxy groups improves hydrophilicity and modulates the electronic structure via p‐π conjugation. Notably, longer alkoxy side chains facilitate fine‐tuning of the COFs' electronic states, resulting in ...

Monitoring and modeling infiltration–recharge dynamics of managed aquifer recharge with desalinated seawater

open access: yes, 2016
. We study the relation between surface infiltration and groundwater recharge during managed aquifer recharge (MAR) with desalinated seawater in an infiltration pond, at the Menashe site that overlies the northern part of the Israeli Coastal Aquifer.

In Situ Polymerized Polyfluorinated Crosslinked Polyether Electrolytes for High‐Voltage Lithium Metal Batteries

open access: yesAdvanced Materials, EarlyView.
In situ polymerized polyfluorinated crosslinked polyether electrolytes are engineered for high‐voltage Li metal batteries. Electron‐withdrawing fluorinated groups enhance oxidative stability, improve interfacial compatibility, and promote inorganic‐rich solid electrolyte interphase formation for uniform Li deposition.

Issues in artificial recharge

open access: yesWater Science and Technology, 1996
Interest in artificial recharge with normal water and sewage effluent continues to increase. Issues discussed in this paper include recharge with infiltration basins, soil-aquifer treatment of sewage effluent, potable use of water from aquifers recharged with sewage effluent, nitrogen removal, pre-treatment of sewage effluent, disinfection, well ...

Optimal Management of a Hawaiian Coastal Aquifer with Near-Shore Marine Ecological Interactions [PDF]

open access: yes
We optimize groundwater management in the presence of marine consequences of submarine groundwater discharge (SGD). Concern for marine biota increases the optimal steady-state head level of the aquifer.
