Circulation of hydraulically ponded turbidity currents and the filling of continental slope minibasins

open access: yesNature Communications
Natural depressions on continental margins termed minibasins trap turbidity currents, a class of sediment-laden seafloor density driven flow. These currents are the primary downslope vectors for clastic sediment, particulate organic carbon, and ...

A Bayesian palaeoenvironmental transfer function model for acidified lakes [PDF]

open access: yes, 2008
A Bayesian approach to palaeoecological environmental reconstruction deriving from the unimodal responses generally exhibited by organisms to an environmental gradient is described.

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.

Simulasi Numeris Tiga Dimensi Kantong Lumpur Bendung Sapon [PDF]

open access: yes, 2008
The success factor of a settling basin planning is the trap efficiency. In reality, it is difficult to create a detailed physical model of the sedimentation process.

Copper Doping Enhances the Activity and Selectivity of Atomically Precise Ag44 Nanoclusters for Photocatalytic CO2 Reduction

open access: yesAdvanced Functional Materials, EarlyView.
By a simple anti‐Galvanic reaction, up to six copper atoms could be preferably doped into the Ag2(SR)5 staple motifs and Ag20 dodecahedral shell of an atomically precise Ag44(SR)30 nanocluster. When anatase TiO2 is used as substrate, the (AgCu)44/TiO2 photocatalyst exhibited much improved activity in photocatalytic CO2 reduction compared to Ag44/TiO2 ...

A Sediment Trapping Experiment at Santa Cruz, Ca.

open access: yesCoastal Engineering 1980, 1980
Santa Cruz Harbor is located on the northern coast of Monterey Bay, California, approximately 104 kilometers south of San Francisco and 22 kilometers north of Moss Landing, as shown in Figures 1 and 2. Harbor construction was authorized by Congress under the Rivers and Harbors Act of 195S, which provided for a harbor to accommodate light-draft vessels ...

Spatial and temporal variability of biogenic isoprene emissions from a temperate estuary [PDF]

open access: yes, 2012
[1] Isoprene is important for its atmospheric impacts and the ecophysiological benefits it affords to emitting organisms; however, isoprene emissions from marine systems remain vastly understudied compared to terrestrial systems.

Self‐supportive Three‐Way Photoelectrochemical System Achieving Uranium Recycling, Organic Oxidation, and Electricity Generation in Complex Waters

open access: yesAdvanced Functional Materials, EarlyView.
A self‐sustaining solar photoelectrochemical cell (SS‐PEC) is developed to recover uranium from aqueous UO22+ with concurrent organic oxidation and electricity production. The monolithical photoanode directly captures electrons from organic compounds, leading to the oxidation of organic compounds and the decomposition of uranium‐organic complexes ...
