Biological Control of Meloidogyne incognita by Aspergillus niger F22 Producing Oxalic Acid. [PDF]

open access: yesPLoS ONE, 2016
Restricted usage of chemical nematicides has led to development of environmentally safe alternatives. A culture filtrate of Aspergillus niger F22 was highly active against Meloidogyne incognita with marked mortality of second-stage juveniles (J2s) and ...

Dehydration mechanism of a small molecular solid: 5-nitrouracil hydrate [PDF]

open access: yes, 2013
Previous studies of the dehydration of 5-nitrouracil (5NU) have resulted in it being classified as a ‘‘channel hydrate’’ in which dehydration proceeds principally by the exit of the water molecules along channels in the structure.

(Dimethylphosphoryl)methanaminium hydrogen oxalate–oxalic acid (2/1) [PDF]

open access: yesActa Crystallographica Section E Structure Reports Online, 2014
The reaction of (dimethylphosphoryl)methanamine (dpma) with oxalic acid in ethanol yielded the title solvated salt, C3H11NOP+·C2HO4−·0.5C2H2O4. Its asymmetric unit consists of one dpmaH+cation, one hydrogen oxalate anion and a half-molecule of oxalic acid located around a twofold rotation axis.

Organic Acid Mixing to Improve ITO Film Etching in Flat Panel Display Manufacture [PDF]

open access: yes
[[abstract]]This study examines how oxalic acid mixed with tartaric acid affect indium tin oxide (ITO) etching. When the ITO films were etched with the mixed solutions of oxalic acid and tartaric acid, the dissociation of tartaric acid impeded the ...

Changes in dissolved iron deposition to the oceans driven by human activity: a 3-D global modelling study [PDF]

open access: yes, 2015
The global atmospheric iron (Fe) cycle is parameterized in the global 3-D chemical transport model TM4-ECPL to simulate the proton- and the organic ligand-promoted mineral-Fe dissolution as well as the aqueous-phase photochemical reactions between the ...

Facet‐Engineered S‐Scheme Heterostructure With Enhanced Active Sites for Efficient Photocatalytic Degradation of Organic Contaminants

open access: yesAdvanced Functional Materials, EarlyView.
The facet‐engineered ZnO/Zn3In2S6 heterostructure, dominated by {001} plane coupling, exposes abundant unsaturated Zn sites with elongated Zn─O bonds, directing photoexcited charge carriers along an S‐scheme pathway and suppressing recombination. Enhanced interfacial Zn adsorption toward bisphenol A and methylene blue further synergistically promotes ...
