interfaces: 2. Mechanics of enhanced (2009)
N. J. Glassmaker, T. Tang, A. Jagota
This study addresses the strength and toughness of generic fibrillar structures. We show that the stress σc required to pull a fibril out of adhesive contact with a substrate has the form σc =...
10.1098/rspa.2002.1057 Crack blunting and the strength of soft elastic solids (2009)
When a material is so soft that the cohesive strength (or adhesive strength, in the case of interfacial fracture) exceeds the elastic modulus of the material, we show that a crack will blunt instead...
Double-walled carbon nanotubes under hydrostatic pressure: Raman experiments and simulations (2007)
Gadagkar, V, Saha, S, Muthu, DVS, Maiti, PK, Lansac, Y, Jagota, A, ...
We have used Raman spectroscopy to study the behavior of double-walled carbon nanotubes (DWNT) under hydrostatic pressure. We find that the rate of change of the tangential mode frequency with...

Collapse of double-walled carbon nanotube bundles under hydrostatic pressure (2006)
Gadagkar, Vikram, Maiti, Prabal K, Lansac, Yves, Jagota, A, Sood, AK
We use classical molecular dynamics simulations to study the collapse of single (SWNT) and double-walled (DWNT) carbon nanotube bundles under hydrostatic pressure. The collapse pressure (p(c)) varies...
Controlled two-dimensional pattern of spontaneously aligned carbon nanotubes (2006)
McLean, R. S., Huang, X. Y., Khripin, C, Jagota, A, Zheng, Ming
We report a simple solution process to form controlled patterns of aligned single-walled carbon nanotubes on solid substrates. The essential step of the process is to deposit a dilute solution of...

Design of biomimetic fibrillar interfaces: 1. Making contact (2004)
N. J. Glassmaker, A. Jagota, J. Kim
This paper explores the contact behaviour of simple fibrillar interfaces designed to mimic natural contact surfaces in lizards and insects. A simple model of bending and buckling of fibrils shows...
Lustig, S.R., Boyes, E.D., French, R.H., Gierke, T.D., Harmer, M.A., Hietpas, P.B., ...
Single-walled carbon nanotubes are efficiently cut to precise submicrometer lengths and very narrow length distributions. Chemical functional groups are placed selectively only at the ends without...
New methods for splice site recognition (2002)
S. Sonnenburg, G. Rätsch, A. Jagota
Abstract. Splice sites are locations in DNA which separate protein-coding regions (exons) from noncoding regions (introns). Accurate splice site detectors thus form important components of...

Splice sites are locations in DNA which separate protein-coding regions (exons) from noncoding regions (introns). Accurate splice site detectors thus form important components of computational gene...
Cohesive Formulations for Delamination in Polymer Layered Composites (1998)
Saigal, S., Muralidhar, S., Jagota, A., Bennison, S. J.
A basic formulation for the delamination response of composites has been developed and validated against experimental data. An energy balance is formulated that relates the applied force to...
