3D Printing Variable Stiffness Foams Using Viscous Thread Instability.

Scientific reports

Lipton JI, Lipson H.
PMID: 27503148
Sci Rep. 2016 Aug 09;6:29996. doi: 10.1038/srep29996.

Additive manufacturing of cellular structures has numerous applications ranging from fabrication of biological scaffolds and medical implants, to mechanical weight reduction and control over mechanical properties. Various additive manufacturing processes have been used to produce open regular cellular structures...

Exciton Localization in Extended π-Electron Systems: Comparison of Linear and Cyclic Structures.

The journal of physical chemistry. B

Thiessen A, Würsch D, Jester SS, Aggarwal AV, Idelson A, Bange S, Vogelsang J, Höger S, Lupton JM.
PMID: 26035080
J Phys Chem B. 2015 Jul 30;119(30):9949-58. doi: 10.1021/acs.jpcb.5b02091. Epub 2015 Jul 16.

We employ five π-conjugated model materials of different molecular shape-oligomers and cyclic structures-to investigate the extent of exciton self-trapping and torsional motion of the molecular framework following optical excitation. Our studies combine steady state and transient fluorescence spectroscopy in...

Unraveling the Electronic Heterogeneity of Charge Traps in Conjugated Polymers by Single-Molecule Spectroscopy.

The journal of physical chemistry letters

Adachi T, Vogelsang J, Lupton JM.
PMID: 26276611
J Phys Chem Lett. 2014 Feb 06;5(3):573-7. doi: 10.1021/jz402621y. Epub 2014 Jan 27.

Charge trapping is taken for granted in modeling the characteristics of organic semiconductor devices, but very few techniques actually exist to spectroscopically pinpoint trap states. For example, trap levels are often assumed to be discrete in energy. Using the...

Crit Care Resusc. 2005 Mar;7(1):22-8.

OBJECTIVE: This review highlights the development and application of modern chest wall cuirass ventilators.DATA SOURCES: Initial animal studies and subsequent publications of applications of various modes of noninvasive cuirass ventilation are recorded.SUMMARY OF REVIEW: Use of the modern cuirass...

Phenylene-ethynylene macrocycles as model systems of interchromophoric interactions in pi-conjugated macromolecules.

The journal of physical chemistry. B

Becker K, Fritzsche M, Höger S, Lupton JM.
PMID: 18386876
J Phys Chem B. 2008 Apr 24;112(16):4849-53. doi: 10.1021/jp800160h. Epub 2008 Apr 03.

Unraveling the complex photophysics of macromolecular pi-conjugated systems requires both the development of suitable model systems to access a particular subset of a material's parameter space and the choice of matching spectroscopic techniques. We address the question of the...

Electrical control of Förster energy transfer.

Nature materials

Becker K, Lupton JM, Müller J, Rogach AL, Talapin DV, Weller H, Feldmann J.
PMID: 16998470
Nat Mater. 2006 Oct;5(10):777-81. doi: 10.1038/nmat1738. Epub 2006 Sep 24.

Bringing together compounds of intrinsically different functionality, such as inorganic nanostructures and organic molecules, constitutes a particularly powerful route to creating novel functional devices with synergetic properties found in neither of the constituents. We introduce nanophotonic functional elements combining...

The role of particle morphology in interfacial energy transfer in CdSe/CdS heterostructure nanocrystals.

Science (New York, N.Y.)

Borys NJ, Walter MJ, Huang J, Talapin DV, Lupton JM.
PMID: 21127250
Science. 2010 Dec 03;330(6009):1371-4. doi: 10.1126/science.1198070.

Nanoscale semiconductor heterostructures such as tetrapods can be used to mimic light-harvesting processes. We used single-particle light-harvesting action spectroscopy to probe the impact of particle morphology on energy transfer and carrier relaxation across a heterojunction. The generic form of...

Spatial anticorrelation between nonlinear white-light generation and single molecule surface-enhanced Raman scattering.

Journal of the American Chemical Society

Walter MJ, Borys NJ, Gaefke G, Höger S, Lupton JM.
PMID: 19053431
J Am Chem Soc. 2008 Dec 17;130(50):16830-1. doi: 10.1021/ja8054518.

We investigate the correlation between plasmon-enhanced nonlinear white-light emission and single-molecule surface-enhanced Raman scattering (SERS) on fractal silver films using a conjugated polymer as a versatile analyte. Single molecule resonance SERS is preferentially observed from sample positions which do...

Hyperfine-field-mediated spin beating in electrostatically bound charge carrier pairs.

Physical review letters

McCamey DR, van Schooten KJ, Baker WJ, Lee SY, Paik SY, Lupton JM, Boehme C.
PMID: 20366393
Phys Rev Lett. 2010 Jan 08;104(1):017601. doi: 10.1103/PhysRevLett.104.017601. Epub 2010 Jan 08.

Organic semiconductors offer a unique environment to probe the hyperfine coupling of electronic spins to a nuclear spin bath. We explore the interaction of spins in electron-hole pairs in the presence of inhomogeneous hyperfine fields by monitoring the modulation...
