SAGE open medical case reports

Jones RW, Parkerson GR, Ottinger M, Rodriguez E, Park B.
PMID: 28255445
SAGE Open Med Case Rep. 2017 Feb 08;5:2050313X17692937. doi: 10.1177/2050313X17692937. eCollection 2017.

OBJECTIVE: We present a case of recurrent bilateral lower extremity venous stasis ulcers in association with a superficial venous aneurysm at the right saphenofemoral junction that was misdiagnosed on preoperative duplex scanning.METHODS: A 53-year-old female presented to our clinic...

Texture and wettability of metallic lotus leaves.

Nanoscale

Frankiewicz C, Attinger D.
PMID: 26537609
Nanoscale. 2016 Feb 21;8(7):3982-90. doi: 10.1039/c5nr04098a.

Superhydrophobic surfaces with the self-cleaning behavior of lotus leaves are sought for drag reduction and phase change heat transfer applications. These superrepellent surfaces have traditionally been fabricated by random or deterministic texturing of a hydrophobic material. Recently, superrepellent surfaces...

A simple add-on microfluidic appliance for accurately sorting small populations of cells with high fidelity.

Journal of micromechanics and microengineering : structures, devices, and systems

Grad M, Young EF, Smilenov L, Brenner DJ, Attinger D.

J Micromech Microeng. 2013;23(11). doi: 10.1088/0960-1317/23/11/117003.

Current advances in single cell sequencing, gene expression and proteomics require the isolation of single cells, frequently from a very small source population. In this work we describe the design and characterization of a manually operated microfluidic cell sorter...

Numerical studies of the transport behavior of a passive solute in a two-dimensional incompressible random flow field.

Physical review. E, Statistical, nonlinear, and soft matter physics

Dentz M, Kinzelbach H, Attinger S, Kinzelbach W.
PMID: 12786486
Phys Rev E Stat Nonlin Soft Matter Phys. 2003 Apr;67(4):046306. doi: 10.1103/PhysRevE.67.046306. Epub 2003 Apr 21.

We study the transport behavior of a passive scalar in a two-dimensional (2D) time-independent Gaussian random velocity field by efficient and highly accurate numerical simulations. The model under consideration has been used in order to gain basic understanding of...

Determination of paper filler Z-distribution by low-vacuum SEM and EDX.

Journal of microscopy

Roux S, Feugeas F, Bach M, Fagon M, Bettinger C, Mourad S, Cornet A.
PMID: 18173644
