Grafting oligothiophenes on surfaces by diazonium electroreduction: a step toward ultrathin junction with well-defined metal/oligomer interface.

Journal of the American Chemical Society

Stockhausen V, Ghilane J, Martin P, Trippé-Allard G, Randriamahazaka H, Lacroix JC.
PMID: 19785424
J Am Chem Soc. 2009 Oct 21;131(41):14920-7. doi: 10.1021/ja9047009.

The functionalization of electrode materials through diazonium electroreduction using a heteroaromatic compound, without phenyl groups, has been investigated for the first time. The electrochemical reduction of 2-aminoterthiophenyldiazonium cation, generated in situ, coats the electrode (glassy carbon (GC), gold or...

A new 1D coordination polymer comprised of [Mn(III)(6)O(2)(Et-sao)(6)(EtOH)(4)(H(2)O)(2)](2+) units and bithiophene dicarboxylato was synthesized by mixing EtsaoH(2) (salicylaldoxime), H(2)btda (2,2'-bithiophene-5,5'-dicarboxylic acid) and Mn(ClO(4))(2)·6H(2)O in the presence of NEt(4)OH. The crystal structure was determined and consists of Mn(6) clusters bridged...

Effects of elevated CO2 on the tolerance of photosynthesis to acute heat stress in C3, C4, and CAM species.

American journal of botany

Wang D, Heckathorn SA, Barua D, Joshi P, Hamilton EW, Lacroix JJ.
PMID: 21632342
Am J Bot. 2008 Feb;95(2):165-76. doi: 10.3732/ajb.95.2.165.

Determining the effect of elevated CO(2) on the tolerance of photosynthesis to acute heat stress (AHS) is necessary for predicting plant responses to global warming because photosynthesis is heat sensitive and AHS and atmospheric CO(2) will increase in the...

Giant plasmon resonance shift using poly(3,4-ethylenedioxythiophene) electrochemical switching.

Journal of the American Chemical Society

Stockhausen V, Martin P, Ghilane J, Leroux Y, Randriamahazaka H, Grand J, Felidj N, Lacroix JC.
PMID: 20662496
J Am Chem Soc. 2010 Aug 04;132(30):10224-6. doi: 10.1021/ja103337d.

Herein, we report the variation of localized surface plasmon resonance (LSPR) of gold nanoparticle (NP) arrays covered by poly(3,4-ethylenedioxythiophene) (PEDOT) as a function of the electronic state of the polymer. Giant shifts and fine-tuning of the LSPR of gold...

Micro/nano-structured polypyrrole surfaces on oxidizable metals as smart electroswitchable coatings.

Santos L, Martin P, Ghilane J, Lacaze PC, Lacroix JC.
PMID: 24063699
ACS Appl Mater Interfaces. 2013 Oct 23;5(20):10159-64. doi: 10.1021/am402846n. Epub 2013 Oct 14.

Polypyrrole (PPy) films were electrodeposited from a pyrrole/sodium salicylate solution in water, through two-dimensional (2-D) polystyrene (PS) templates self-assembled on various oxidizable metals, after which the template was removed by dissolution in tetrahydrofuran (THF). The resulting PPy films were...

Language and emotional abilities in children with Williams syndrome and children with autism spectrum disorder: similarities and differences.

Pediatric health, medicine and therapeutics

Lacroix A, Famelart N, Guidetti M.

Pediatric Health Med Ther. 2016 Jul 22;7:89-97. doi: 10.2147/PHMT.S66347. eCollection 2016.

Williams syndrome (WS) is a genetic disease with a relatively homogeneous profile: relatively well-preserved language, impaired cognitive activities, and hypersociability. Autism spectrum disorder (ASD) refers to a group of individuals with impairments in aspects of communication and a particular...
