Efficient Enantiomeric Selectivity Separation Via Homochiral Graphene Oxide Membrane

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A new type of chiral graphene oxide (GO) membrane is proposed that exhibits a separation factor of up to 20.1 as well as a preferential enantiomer flux of 4.5 mmol m−2 h−1. Moreover, the only first FPLC‐compatible column has been further developed via stacking these chiral GO membranes.

The role of natural organic ligands in transformations of iron chemistry in seawater and their effect on the bioavailability of iron to marine phytoplankton [PDF]

open access: yes, 2014
University of Technology Sydney. Faculty of Science.It is widely accepted that the complexation of iron (Fe) with organic compounds is the primary factor that regulates Fe reactivity and its bioavailability to phytoplankton in the open ocean.

Confinement−Adsorption Synergy in Hybrid Carbon‐Coated Separator Enables Stable High‐Rate Quinone Cathode for Magnesium Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A sulfur‐containing heterocyclic quinone cathode for rechargeable magnesium batteries is coupled with a GO/MWCNTs–COOH separator that establishes a confinement–adsorption regulation mechanism, thereby significantly accelerating Mg2+ reaction kinetics and minimizing active‐material loss.

Successful Implementation of Environmental Policy and Governance: Understanding and Modeling Micro Governance

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Successful implementation of environmental policy and governance highly depends on the capacity to know about, build new and utilize existing governance structures. However, the theoretical tools and available methods to assess the complexity of emerging or existing structures are rather limited.

Use of high-dimensional spectral data to evaluate organic matter, reflectance relationships in soils [PDF]

open access: yes
Recent breakthroughs in remote sensing technology have led to the development of a spaceborne high spectral resolution imaging sensor, HIRIS, to be launched in the mid-1990s for observation of earth surface features. The effects of organic carbon content

Soil organic matter and mineral content as crucial factors for the fate of tetracycline in soils

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract Soil self‐cleaning ability and bioavailability of different pollutants are strongly dependent on the soil properties. It is not easy to determine effects of individual soil characteristics because they can impact together often in a synergic effect.

Harvesting of Residual Soil Phosphorus on Intensive Shallot Farming in Brebes, Indonesia [PDF]

open access: yes, 2018
Accumulated residual soil phosphorus (P) on shallots farming in Brebes can be harvested through the application of ameliorants or bio-fertilizers. The information on the effect of ameliorants and bio-fertilizers on soil P fractions is limited.
