This paper shows the extent to which people in Funafuti–the main island of Tuvalu–are intending to migrate in response to climate change. It presents evidence collected from Funafuti to challenge the widely held assumption that climate change is, will,...

Highly cis-1,4 polymerisation of isoprene and syndiospecific polymerisation of styrene were conducted using the same borohydrido half-sandwich scandium pre-initiator.

Dose-dependent skeletal deficits due to varied reductions in mechanical loading in rats.

NPJ microgravity

Reduced skeletal loading leads to marked bone loss. Animal models of hindlimb suspension are widely used to assess alterations in skeleton during the course of complete unloading. More recently, the effects of partial unloading on the musculoskeletal system have...

17O NMR gives unprecedented insights into the structure of supported catalysts and their interaction with the silica carrier.

Journal of the American Chemical Society

Merle N, Trébosc J, Baudouin A, Rosal ID, Maron L, Szeto K, Genelot M, Mortreux A, Taoufik M, Delevoye L, Gauvin RM.
PMID: 22571376

Flame silica was surface-labeled with (17)O, through isotopic enrichment of both siloxanes and silanols. After heat treatment at 200 and 700 °C under vacuum, the resulting partially dehydroxylated silica materials were investigated by high-field solid-state (1)H and (17)O NMR....

Longitudinal time course of muscle impairments during partial weight-bearing in rats.

In the near future, space agencies plan to send the first crews for extended stays on the Moon and Mars, where gravity is significantly reduced compared to Earth (0.16×

Catalytic Chain Transfer (co-)Polymerization: Unprecedented Polyisoprene CCG and a New Concept to Tune the Composition of a Statistical Copolymer.

Macromolecular rapid communications

Valente A, Zinck P, Mortreux A, Visseaux M.
PMID: 21706636
Macromol Rapid Commun. 2009 Apr 01;30(7):528-31. doi: 10.1002/marc.200800734. Epub 2009 Jan 21.

Borohydrido-halflanthanidocene/dialkylmagnesium combinations are found to be powerful catalytic systems for the chain transfer polymerization of isoprene and its copolymerization with styrene. A behavior close to a lanthanide catalyzed polyisoprene chain growth on magnesium is reported. Transmetalation is further shown...

Well-defined silica-supported rare-earth silylamides.

Inorganic chemistry

Gauvin RM, Delevoye L, Hassan RA, Keldenich J, Mortreux A.
PMID: 17249652
Inorg Chem. 2007 Feb 19;46(4):1062-70. doi: 10.1021/ic0610334. Epub 2007 Jan 24.

Rare-earth silylamides [Ln{N(SiMe3)2}3] [1a-d, Ln = Y (1a), La (1b), Nd (1c), Sm (1d)] react with partially dehydroxylated silica to generate the singly surface-bonded species [(Si-O)Ln{N(SiMe3)2}2] (2a-d). Trimethylsilylation of silanols occurs during the grafting process, affording in fine a...

New synthesis of 1,4-diketones via rhodium-catalysed 1,4 carbonylative addition of arylboronic acids to alpha,beta-unsaturated ketones.

Chemical communications (Cambridge, England)

The reaction of various arylboronic acids with alpha,beta-unsaturated ketones under CO pressure and in the presence of rhodium catalyst yields 1,4-diketones.

Cationic borohydrido-neodymium complex: synthesis, characterization and its application as an efficient pre-catalyst for isoprene polymerisation.

Dalton transactions (Cambridge, England : 2003)

Visseaux M, Mainil M, Terrier M, Mortreux A, Roussel P, Mathivet T, Destarac M.

The cationic borohydrido lanthanide complex [Nd(BH4)2(THF)5][B(C6F5)4]1, prepared from the reaction of Nd(BH4)3(THF)3 with [HNMe2Phl[B(C6F5)4], is highly active towards isoprene polymerisation upon activation with Al(i-Bu)3, whereas the in situ prepared ternary catalytic combination Nd(BH4)3(THF)3/[HNMe2Ph][B(C6F5)4]/Al(i-Bu)3, albeit less active, displays higher cis-selectivity...
