Viscoelastic properties and efficient acoustic damping in confined polymer nano-layers at GHz frequencies.

Scientific reports

Hettich M, Jacob K, Ristow O, Schubert M, Bruchhausen A, Gusev V, Dekorsy T.
PMID: 27633351
Sci Rep. 2016 Sep 16;6:33471. doi: 10.1038/srep33471.

We investigate the viscoelastic properties of confined molecular nano-layers by time resolved optical pump-probe measurements. Access to the elastic properties is provided by the damping time of acoustic eigenmodes of thin metal films deposited on the molecular nano-layers which...

Proteomic Stable Isotope Probing Reveals Biosynthesis Dynamics of Slow Growing Methane Based Microbial Communities.

Frontiers in microbiology

Marlow JJ, Skennerton CT, Li Z, Chourey K, Hettich RL, Pan C, Orphan VJ.
PMID: 27199908
Front Microbiol. 2016 Apr 29;7:563. doi: 10.3389/fmicb.2016.00563. eCollection 2016.

Marine methane seep habitats represent an important control on the global flux of methane. Nucleotide-based meta-omics studies outline community-wide metabolic potential, but expression patterns of environmentally relevant proteins are poorly characterized. Proteomic stable isotope probing (proteomic SIP) provides additional...

Collective Modes and Structural Modulation in Ni-Mn-Ga(Co) Martensite Thin Films Probed by Femtosecond Spectroscopy and Scanning Tunneling Microscopy.

Physical review letters

Schubert M, Schaefer H, Mayer J, Laptev A, Hettich M, Merklein M, He C, Rummel C, Ristow O, Großmann M, Luo Y, Gusev V, Samwer K, Fonin M, Dekorsy T, Demsar J.

Phys Rev Lett. 2015 Aug 14;115(7):076402. doi: 10.1103/PhysRevLett.115.076402. Epub 2015 Aug 13.

The origin of the martensitic transition in the magnetic shape memory alloy Ni-Mn-Ga has been widely discussed. While several studies suggest it is electronically driven, the adaptive martensite model reproduced the peculiar nonharmonic lattice modulation. We used femtosecond spectroscopy...

Strain-resolved microbial community proteomics reveals simultaneous aerobic and anaerobic function during gastrointestinal tract colonization of a preterm infant.

Biotechnol Biofuels. 2014 Dec 03;7(1):165. doi: 10.1186/s13068-014-0165-z. eCollection 2014.

BACKGROUND: Chemical and physical pretreatment of lignocellulosic biomass improves substrate reactivity for increased microbial biofuel production, but also restricts growth via the release of furan aldehydes, such as furfural and 5-hydroxymethylfurfural (5-HMF). The physiological effects of these inhibitors on...

When reducing the size of a material from bulk down to nanoscale, the enhanced surface-to-volume ratio and the presence of interfaces make the properties of nano-objects very sensitive not only to confinement effects but also to their local environment....
