The Phase Behavior of Mixed Lipid Membranes in Presence of the Rippled Phase (2007)
Shimokawa, N., Komura, S., Andelman, D.
We propose a model describing liquid-solid phase coexistence in mixed lipid membranes by including explicitly the occurrence of a rippled phase. For a single component membrane, we employ a previous...

Mechanical, adhesive and thermodynamic properties of hollow nanoparticles (2002)
Schwarz, U. S., Safran, S. A., Komura, S.
When sheets of layered material like C, WS$_2$ or BN are restricted to finite sizes, they generally form single- and multi-walled hollow nanoparticles in order to avoid dangling bonds. Using...
Optimizing the procedure for equal-channel angular pressing for maximum superplasticity (2001)
Komura, S., Furukawa, M., Horita, Z., Nemoto, M., Langdon, T.G.
The imposition of severe plastic straining on an Al–3% Mg–0.2% Sc alloy through equal-channel angular pressing (ECAP) reduces the grain size to ca. 0.2 μm and provides an opportunity to achieve...
Furukawa, M., Utsunomiya, A., Komura, S., Horita, Z., Nemoto, M., Langdon, T.G.
Ultrafine grain sizes may be achieved in materials subjected to severe plastic deformation through processing procedures such as equal-channel angular pressing (ECAP). Experiments were conducted to...
Komura, S., Horita, Z., Furukawa, M., Nemoto, M., Langdon, T.G.
An Al-3 pct Mg-0.2 pct Sc alloy was fabricated by casting and subjected to equal-channel angular pressing to reduce the grain size to ~0.2 m. Very high tensile elongations were achieved in this alloy...

Influence of scandium on superplastic ductilities in an Al-Mg-Sc alloy (2000)
Komura, S., Horita, Z., Furukawa, M., Nemoto, M., Langdon, T.G.
Ultrafine grain sizes, of the order of approximately 0.2 μm, may be introduced into Al-Mg-Sc alloys by subjecting the material to severe plastic deformation through the process of equal-channel...
Deformation and tribology of multi-walled hollow nanoparticles (2000)
Schwarz, U. S., Komura, S., Safran, S. A.
Multi-walled hollow nanoparticles made from tungsten disulphide (WS$_2$) show exceptional tribological performance as additives to liquid lubricants due to effective transfer of low shear strength...
Fujita, T., Komura, S., Horita, Z., Langdon, T.G.
This paper describes grain refinement of an Al-3%Mg-0.2%Sc alloy using the equal-channel angular pressing(ECAP) technique at room temperature. It is shown that a grain size of 0.2.MU.m is obtained...
