Microbial growth patterns described by fractal geometry.

• Martin Obert, Peter Pfeifer, M Sernetz
• Journal of bacteriology
• 1990

Fractal geometry has made important contributions to understanding the growth of inorganic systems in such processes as aggregation, cluster formation, and dendritic growth. In biology, fractal… (More)

Power-law fluctuations in phase-separated lipid membranes.

• Roland Winter, A Gabke, Claus Czeslik, Peter Pfeifer
• Physical review. E, Statistical physics, plasmas…
• 1999

The spatial structure of three binary lipid mixtures, prepared as multilamellar vesicles, was studied by small-angle neutron scattering. In the fluid-gel coexistence region, large-scale concentration… (More)

Gas Diffusion through the Fractal Landscape of the Lung : How Deep Does Oxygen Enter the Alveolar System ?

• Chen Hou, Stefan Gheorghiu, Marc-Olivier Coppens, Virginia H. Huxley, Peter Pfeifer
• 2005

We investigate oxygen transport to and across alveolar membranes in the human lung, the last step in the chain of events that takes oxygen through the bronchial airways to the peripheral, acinar… (More)

Nanospace engineering of KOH activated carbon.

• Jimmy Romanos, Matt Beckner, +6 authors Peter Pfeifer
• Nanotechnology
• 2012

This paper demonstrates that nanospace engineering of KOH activated carbon is possible by controlling the degree of carbon consumption and metallic potassium intercalation into the carbon lattice… (More)

Reverse Engineering of Oxygen Transport in the Lung: Adaptation to Changing Demands and Resources through Space-Filling Networks

• Chen Hou, Stefan Gheorghiu, Virginia H. Huxley, Peter Pfeifer
• PLoS Computational Biology
• 2010

The space-filling fractal network in the human lung creates a remarkable distribution system for gas exchange. Landmark studies have illuminated how the fractal network guarantees minimum energy… (More)

Nearly space-filling fractal networks of carbon nanopores.

• Peter Pfeifer, Françoise Ehrburger-Dolle, +6 authors Dr. John D. Voss
• Physical review letters
• 2002

Small-angle x-ray scattering, nitrogen adsorption, and scanning tunneling microscopy show that a series of activated carbons host an extended fractal network of channels with dimension D(p) = 2.8-3.0… (More)

Hypothetical high-surface-area carbons with exceptional hydrogen storage capacities: open carbon frameworks.

Steroid profiles of healthy individuals.

• Peter Pfeifer, G erhard Spiteller
• Journal of chromatography
• 1981

Urine steroid profiles of healthy individuals can be divided into two groups according to greatly different excretion rates of dehydroepiandrosterone (DHEA). About 80% of the population show an… (More)
