Der Unfallchirurg

Lehmann U, Gobiet W, Regel G, Dhaher SA, Krah B, Steinbeck K, Tscherne H.
PMID: 27372728
Unfallchirurg. 1997 Jul;100(7):552-60. doi: 10.1007/s001130050157.

The aim of this study was to identify, in (pre-) clinically obtained data, parameters predicting the outcome of patients with multiple trauma and severe head injury. Fifty-eight patients aged 27±10 years were investigated an average of 5.8 years after...

Distinguishing Self-Assembled Pyrene Structures from Exfoliated Graphene.

Langmuir : the ACS journal of surfaces and colloids

Varenik M, Green MJ, Regev O.
PMID: 27723350
Langmuir. 2016 Oct 18;32(41):10699-10704. doi: 10.1021/acs.langmuir.6b03379. Epub 2016 Oct 10.

Sonication-assisted graphene production from graphite is a popular lab-scale approach in which ultrasound energy breaks down graphite sheets into graphene flakes in aqueous medium. Dispersants (surfactant molecules) are incorporated into the solution to prevent individual graphene flakes from reaggregating....

Graphite-to-Graphene: Total Conversion.

Advanced materials (Deerfield Beach, Fla.)

Buzaglo M, Bar IP, Varenik M, Shunak L, Pevzner S, Regev O.
PMID: 27991687
Adv Mater. 2017 Feb;29(8). doi: 10.1002/adma.201603528. Epub 2016 Dec 19.

The rush to develop graphene applications mandates mass production of graphene sheets. However, the currently available complex and expensive production technologies are limiting the graphene commercialization. The addition of a protective diluent to graphite during ball-milling is demonstrated to...

German cohort of HCV mono-infected and HCV/HIV co-infected patients reveals relative under-treatment of co-infected patients.

AIDS research and therapy

Beisel C, Heuer M, Otto B, Jochum J, Schmiedel S, Hertling S, Degen O, Lüth S, van Lunzen J, Schulze Zur Wiesch J.
PMID: 25006340
AIDS Res Ther. 2014 Jul 01;11:16. doi: 10.1186/1742-6405-11-16. eCollection 2014.

BACKGROUND: Current German and European HIV guidelines recommend early evaluation of HCV treatment in all HIV/HCV co-infected patients. However, there are still considerable barriers to initiate HCV therapy in everyday clinical practice. This study evaluates baseline characteristics, "intention-to-treat" pattern...

The complex injury of the elbow.

Der Orthopade

Regel G, Weinberg AM, Seekamp A, Blauth M, Tscherne H.
PMID: 28246868
Orthopade. 1997 Dec;26(12):1020-1029. doi: 10.1007/PL00003357.

The complex injury is characterized by a fracture and/or dislocation of the elbow in association with a serial injury of the upper extremity, or a severe soft tissue trauma , or a prolonged ischemia caused by vascular injury or...

PS/CTAB/silica composites from room temperature polymerization of high internal phase emulsion gels.

Journal of colloid and interface science

Zhang T, Xu G, Li ZF, Regev O, Maddumaarachchi M, Blum FD.
PMID: 25897852
J Colloid Interface Sci. 2015 Aug 01;451:161-9. doi: 10.1016/j.jcis.2015.04.002. Epub 2015 Apr 06.

Polystyrene (PS)/cetyltrimethylammonium bromide (CTAB)/silica composites were prepared by CTAB-catalyzed in-situ polymerization of high internal phase emulsion gels (HIPE gels) at room temperature. The room temperature approach in HIPE gels yielded mono-dispersed PS/CTAB/silica spherical composite particles with sizes of 121...

Performance enhancement of a graphene-zinc phosphide solar cell using the electric field-effect.

Nano letters

Vazquez-Mena O, Bosco JP, Ergen O, Rasool HI, Fathalizadeh A, Tosun M, Crommie M, Javey A, Atwater HA, Zettl A.
PMID: 25058004
Nano Lett. 2014 Aug 13;14(8):4280-5. doi: 10.1021/nl500925n. Epub 2014 Jul 29.

The optical transparency and high electron mobility of graphene make it an attractive material for photovoltaics. We present a field-effect solar cell using graphene to form a tunable junction barrier with an Earth-abundant and low cost zinc phosphide (Zn3P2)...

A Cryo-TEM Study of Protein-Surfactant Gels and Solutions.

Journal of colloid and interface science

Morén AK, Regev O, Khan A.

J Colloid Interface Sci. 2000 Feb 15;222(2):170-178. doi: 10.1006/jcis.1999.6570.

Oppositely charged globular protein and surfactant systems, such as lysozyme-sodium dodecyl sulfate (SDS) and ovalbumin-dodecyltrimethylammonium chloride (DOTAC) form precipitate, gel, and colorless solution in water over a wide concentration range. Bluish solutions are also recognized in connection with the...
