ACS Appl Mater Interfaces. 2016 Sep 14;8(36):23729-38. doi: 10.1021/acsami.6b07599. Epub 2016 Aug 30.

Photocatalytic H2 generation is investigated over a series of Ga-modified ZnO photocatalysts that were prepared by hydrothermal methods. It is found that the structural, textural, and optoelectronic properties remarkably depend on the Ga content. The photocatalytic activity is higher...

While Amazonian forests are extraordinarily diverse, the abundance of trees is skewed strongly towards relatively few 'hyperdominant' species. In addition to their diversity, Amazonian trees are a key component of the global carbon cycle, assimilating and storing more carbon...

Morphological Evolution of Noble Metal Nanoparticles in Chloroform: Mechanism of Switching on/off by Protic Species.

RSC advances

Douglas-Gallardo OA, Gomez CG, Macchione MA, Cometto FP, Coronado EA, Macagno VA, Pérez MA.
PMID: 26889378
RSC Adv. 2015;5(122):100488-100497. doi: 10.1039/C5RA17529A.

The morphological stability/morphological reshaping of noble metal nanoparticles are studied experimentally in order to unravel the chemical mechanisms lying beneath. Gold and silver nanoparticles (AuNPs and AgNPs, respectively) formed in chloroformic environment are used, as model synthetic systems, to...

Sherif S, Rubio-Bollinger G, Pinilla-Cienfuegos E, Coronado E, Cuevas JC, Agraït N.
PMID: 26133791
Nanotechnology. 2015 Jul 24;26(29):291001. doi: 10.1088/0957-4484/26/29/291001. Epub 2015 Jul 02.

We demonstrate large rectification ratios (> 100) in single-molecule junctions based on a metal-oxide cluster (polyoxometalate), using a scanning tunneling microscope (STM) both at ambient conditions and at low temperature. These rectification ratios are the largest ever observed in...
