Light‐Induced Accumulation of Micro‐ and Nanoplastics from Water Dispersion by Optoelectronic Lithium Niobate Platforms

open access: yesAdvanced Materials Interfaces, EarlyView.
An emergent photo‐electrohydrodynamic ejection technique, based on optoelectronic lithium niobate platforms, combined with Raman spectroscopy, is successfully applied to the capture, accumulation and identification of typical contaminant micro‐ and nano‐plastics.

2019 State-of-the-Science of Dispersants and Dispersed Oil (DDO) in U.S. Arctic Waters: Public Health and Food Safety [PDF]

open access: yes, 2019
Chemical dispersants were employed on an unprecedented scale during the Deepwater Horizon oil spill in the Gulf of Mexico, and could be a response option should a large spill occur in Arctic waters. The use of dispersants in response to that spill raised

Superhydrophilic TiO2/WO2.72 Nanocomposites Boost PES Membranes Performance for Natural Spring Water Decontamination

open access: yesAdvanced Materials Interfaces, EarlyView.
TiO2 membrane photocatalytic activity outperformed TiO2/WO2.72 membrane. TiO2/WO2.72 membrane outperformed in hydrophilicity, permeation, rejection and antifouling. UV254 absorbance (0.14) was reduced in natural spring water with TiO2/WO2.72 membrane.

Mechanically Tunable Mechanochromic Device with Covert‐Overt Structural Color and Modulation of its Transparency

open access: yesAdvanced Materials Interfaces, EarlyView.
This study presents a novel mechanically responsive optical device that modulates light transmission and generates iridescent structural colors under reflection. The optical transition arises from the exposure of nanoparticles upon stretching, which are initially embedded beneath the surface.

Virus Effect on Marine Synechococcus Spp. Loss in Subtropical Western Pacific Coastal Waters During Winter

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2015
Little is known about microbial processes and the effect that viruses have on Synechococcus spp. in aquatic environments. This study investigated diel variations in the Synechococcus spp. abundance in three size-fractionated water samples (200, 10, and 2

Ecosystems as climate controllers – biotic feedbacks (a review) [PDF]

open access: yes, 2008
There is good evidence that higher global temperature will promote a rise of green house gas levels, implying a positive feedback which will increase the effect of the anthropogenic emissions on global temperatures.
