Photoactivation of NV Centers in Diamond via Continuous Wave Laser Illumination of Shallow As‐Implanted Nitrogen

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates an alternative method of creating charge‐stable negatively charged nitrogen vacancy (NV−) centers close to the diamond surface without high‐temperature annealing. By illuminating nitrogen‐implanted regions with a continuous‐wave 405 nm laser, NV− centers are induced, exhibiting electron spin coherence properties suitable for ...

State Level Efforts to Regulate Agricultural Sources of Water Quality Impairment [PDF]

open access: yes, 2013
The U.S. policy regarding water quality is codified in the 1972 Clean Water Act and amendments. The Act formally distinguishes between point sources and nonpoint sources of pollution entering waterways and assigns primary responsibility for controlling ...

Cu‐Based MOF/TiO2 Composite Nanomaterials for Photocatalytic Hydrogen Generation and the Role of Copper

open access: yesAdvanced Functional Materials, EarlyView.
HKUST‐1/TiO2 composite materials show a very high photocatalytic hydrogen evolution rate which increases as a function of the irradiation time until reaching a plateau and even surpasses the performance of the 1%Pt/TiO2 material after three photocatalytic cycles.

From frequent hurricanes to the Deepwater Horizon oil spill in coastal Louisiana: the impact of regulatory change

open access: yesEcology and Society, 2014
The issue of whether adaptations to past disasters can impede adaptation to new disasters of a different type or intensity will be analyzed by examining the transition from frequent hurricanes to the Deepwater Horizon oil spill in coastal Louisiana.

Atomic Size Misfit for Electrocatalytic Small Molecule Activation

open access: yesAdvanced Functional Materials, EarlyView.
This review explores the application and mechanisms of atomic size misfit in catalysis for small molecule activation, focusing on how structural defects and electronic properties can effectively lower the energy barriers of chemical bonds in molecules like H2O, CO2, and N2.
