Isomerization of metastable amine radical cations by dissociation-recombination.

European journal of mass spectrometry (Chichester, England)

Pedersen AH, Nielson CB, Bojesen G, Hammerum S.
PMID: 26307742
Eur J Mass Spectrom (Chichester). 2015;21(3):635-9. doi: 10.1255/ejms.1342.

The metastable molecular ions of primary aliphatic amines branched at C2 can isomerize by cleavage-recombination, thereby facilitating fragmentation reactions that require less energy than simple cleavage of the initial molecular ion. This process complements the reactions described by Audier...

Plasmon resonances of Ag capped Si nanopillars fabricated using mask-less lithography.

Optics express

Wu K, Rindzevicius T, Schmidt MS, Mogensen KB, Xiao S, Boisen A.
PMID: 26074549
Opt Express. 2015 May 18;23(10):12965-78. doi: 10.1364/OE.23.012965.

Localized surface plasmon resonances (LSPR) and plasmon couplings in Ag capped Si Nanopillar (Ag NP) structures are studied using 3D FEM simulations and dark-field scattering microscopy. Simulations show that a standalone Ag NP supports two LSPR modes, i.e. the...

Effectiveness of Optional Videoconferencing-Based Treatment of Alcohol Use Disorders: Randomized Controlled Trial.

JMIR mental health

Tarp K, Bojesen AB, Mejldal A, Nielsen AS.
PMID: 28963093
JMIR Ment Health. 2017 Sep 29;4(3):e38. doi: 10.2196/mental.6713.

BACKGROUND: Treatment of alcohol use disorders (AUDs) is characterized by an adherence rate below 50%. Clinical research has found that patient adherence enhances treatment effect; hence, health authorities, clinicians, and researchers strive to explore initiatives contributing to patients receiving...

Aluminum orthovanadate (AlVO4): synthesis and characterization by (27)Al and 51V MAS and MQMAS NMR spectroscopy.

Inorganic chemistry

Nielsen UG, Boisen A, Brorson M, Jacobsen CJ, Jakobsen HJ, Skibsted J.
PMID: 12444788
Inorg Chem. 2002 Dec 02;41(24):6432-9. doi: 10.1021/ic0204023.

Polycrystalline samples of AlVO(4) have been prepared by two methods of synthesis and characterized by (27)Al and (51)V MAS NMR spectroscopy at 14.1 T. The MAS NMR spectra clearly reveal that essentially pure samples with minor impurities of V(2)O(5)...

Environmental sensors based on micromachined cantilevers with integrated read-out.

Ultramicroscopy

Boisen A, Thaysen J, Jensenius H, Hansen O.
PMID: 10741646
Ultramicroscopy. 2000 Feb;82(1):11-6. doi: 10.1016/s0304-3991(99)00148-5.

An AFM probe with integrated piezoresistive read-out has been developed and applied as a cantilever-based environmental sensor. The probe has a built-in reference cantilever, which makes it possible to subtract background drift directly in the measurement. Moreover, the integrated...

Diffusion of water into SU-8 microcantilevers.

Physical chemistry chemical physics : PCCP

Liu C, Liu Y, Sokuler M, Fell D, Keller S, Boisen A, Butt HJ, Auernhammer GK, Bonaccurso E.
PMID: 20607179
Phys Chem Chem Phys. 2010 Sep 21;12(35):10577-83. doi: 10.1039/c002478c. Epub 2010 Jul 07.

We present a method to monitor the diffusion of liquid molecules in polymers. A microdrop of water is deposited by a piezoelectric drop generator onto the upper surface of a cantilever made of SU-8 based photoresist. In response, the...

Photothermal infrared spectroscopy of airborne samples with mechanical string resonators.

Analytical chemistry

Yamada S, Schmid S, Larsen T, Hansen O, Boisen A.
PMID: 24083320
Anal Chem. 2013 Nov 05;85(21):10531-5. doi: 10.1021/ac402585e. Epub 2013 Oct 21.

Micromechanical photothermal infrared spectroscopy is a promising technique, where absorption-related heating is detected by frequency detuning of microstring resonators. We present photothermal infrared spectroscopy with mechanical string resonators providing rapid identification of femtogram-scale airborne samples. Airborne sample material is...

Real-time single airborne nanoparticle detection with nanomechanical resonant filter-fiber.

Scientific reports

Schmid S, Kurek M, Adolphsen JQ, Boisen A.
PMID: 23411405
Sci Rep. 2013;3:1288. doi: 10.1038/srep01288.

Nanomechanical resonators have an unprecedented mass sensitivity sufficient to detect single molecules, viruses or nanoparticles. The challenge with nanomechanical mass sensors is the direction of nano-sized samples onto the resonator. In this work we present an efficient inertial sampling...

Low-power photothermal probing of single plasmonic nanostructures with nanomechanical string resonators.

Nano letters

Schmid S, Wu K, Larsen PE, Rindzevicius T, Boisen A.
PMID: 24697597
Nano Lett. 2014 May 14;14(5):2318-21. doi: 10.1021/nl4046679. Epub 2014 Apr 07.

We demonstrate the direct photothermal probing and mapping of single plasmonic nanostructures via the temperature-induced detuning of nanomechanical string resonators. Single Au nanoslits and nanorods are illuminated with a partially polarized focused laser beam (λ = 633 nm) with...
