Renzler M, Harnisch M, Daxner M, Kranabetter L, Kuhn M, Scheier P, Echt O.
PMID: 27035406
Phys Chem Chem Phys. 2016 Apr 21;18(15):10623-9. doi: 10.1039/c6cp00764c. Epub 2016 Apr 01.

Electron ionization of helium droplets doped with sodium, potassium or cesium results in doubly and, for cesium, triply charged cluster ions. The smallest observable doubly charged clusters are Na9(2+), K11(2+), and Cs9(2+); they are a factor two to three...

Reversed Intestinal Rotation Presented as Bowel Obstruction in a Pregnant Woman.

Case reports in surgery

Aranovich D, Schrier I.
PMID: 26075133
Case Rep Surg. 2015;2015:870437. doi: 10.1155/2015/870437. Epub 2015 May 17.

A rare case of complete large bowel obstruction in a pregnant woman, without previous surgical history, due to previously undiagnosed reversed intestinal rotation is presented. The young woman was admitted with progressive nausea and vomiting which did not respond...

Performance of SEM scintillation detector evaluated by modulation transfer function and detective quantum efficiency function.

Scanning

Bok J, Schauer P.
PMID: 24323770
Scanning. 2014 Jul-Aug;36(4):384-93. doi: 10.1002/sca.21130. Epub 2013 Dec 03.

In the paper, the SEM detector is evaluated by the modulation transfer function (MTF) which expresses the detector's influence on the SEM image contrast. This is a novel approach, since the MTF was used previously to describe only the...

Helium Droplets Doped with Sulfur and C.

The journal of physical chemistry. C, Nanomaterials and interfaces

Harnisch M, Weinberger N, Denifl S, Scheier P, Echt O.
PMID: 26045732
J Phys Chem C Nanomater Interfaces. 2015 May 21;119(20):10919-10924. doi: 10.1021/jp510870x. Epub 2014 Dec 23.

Clusters of sulfur are grown by passing superfluid helium nanodroplets through a pickup cell filled with sulfur vapor. In some experiments the droplets are codoped with C

Comparison of Surfactant Distributions in Pressure-Sensitive Adhesive Films Dried from Dispersion under Lab-Scale and Industrial Drying Conditions.

ACS applied materials & interfaces

Baesch S, Siebel D, Schmidt-Hansberg B, Eichholz C, Gerst M, Scharfer P, Schabel W.
PMID: 26953641
ACS Appl Mater Interfaces. 2016 Mar;8(12):8118-28. doi: 10.1021/acsami.6b00830. Epub 2016 Mar 17.

Film-forming latex dispersions are an important class of material systems for a variety of applications, for example, pressure-sensitive adhesives, which are used for the manufacturing of adhesive tapes and labels. The mechanisms occurring during drying have been under intense...

High-Resolution Electron Attachment to the Water Dimer Embedded in Helium Droplets: Direct Observation of the Electronic Conduction Band Formation.

The journal of physical chemistry letters

Jabbour Al Maalouf E, Neustetter M, Illenberger E, Scheier P, Denifl S.
PMID: 28467713
J Phys Chem Lett. 2017 May 18;8(10):2220-2223. doi: 10.1021/acs.jpclett.7b00691. Epub 2017 May 05.

For bulk liquid helium the bottom of the conduction band (V

Digitally Printed Dewetting Patterns for Self-Organized Microelectronics.

Advanced materials (Deerfield Beach, Fla.)

Eckstein R, Alt M, Rödlmeier T, Scharfer P, Lemmer U, Hernandez-Sosa G.
PMID: 27346645
Adv Mater. 2016 Sep;28(35):7708-15. doi: 10.1002/adma.201602082. Epub 2016 Jun 27.

Self-organization of functional materials induced by low surface-energetic direct printed structures is presented. This study investigates fundamental fluid and substrate interactions and fabricates all-printed small area organic photodetectors with On-Off ratios of ≈10(5) and dark current densities of ≈10(-4)...

Helium isotope enrichment by resonant tunneling through nanoporous graphene bilayers.

The journal of physical chemistry. A

Mandrà S, Schrier J, Ceotto M.
PMID: 24854987
J Phys Chem A. 2014 Aug 21;118(33):6457-65. doi: 10.1021/jp502548r. Epub 2014 May 22.

Graphene is impermeable to gases, but introducing subnanometer pores can allow for selective gas separation. Because graphene is only one atom thick, tunneling can play an important role, especially for low-mass gases such as helium, and this has been...

Electron-impact induced fragmentation of fullerene ions.

Physical review letters

Hathiramani D, Aichele K, Arnold W, Huber K, Salzborn E, Scheier P.
PMID: 11030961
Phys Rev Lett. 2000 Oct 23;85(17):3604-7. doi: 10.1103/PhysRevLett.85.3604.

The C2 fragmentation of fullerene ions C(q+)(60) (q = 1,2,3) induced by electron impact was studied for the first time. The cross sections for the loss of a C2 fragment indicate the presence of two different processes. At low...

Embedded neural networks: exploiting constraints.

Neural networks : the official journal of the International Neural Network Society

Scheier C, Pfeifer R, Kunyioshi Y.
PMID: 12662767
Neural Netw. 1998 Oct;11(7):1551-1569. doi: 10.1016/s0893-6080(98)00084-7.

Using concepts and tools of embodied cognitive science, we investigate the implications of embedding neural networks in a physical structure, the body of a robot. Embedding a neural network in a body provides constraints that can be exploited for...

Dissociative electron attachment to gas-phase glycine.

Analytical and bioanalytical chemistry

Ptasinska S, Denifl S, Abedi A, Scheier P, Märk TD.
