A sponge is an elastic solid with connected pores. When immersed in water, the sponge absorbs water. When a saturated sponge is squeezed, water will come out. More generally, the subject is known as diffusion in elastic solids, or elasticity of fluid-infiltrated porous solids, or poroelasticity. The theory has been applied to diverse phenomena. Here are a few examples.

（以下简称）：锁志刚教授您好！首先非常感谢您接受我的采访。我是从ISI科学论文引证系统知道您。2002年8月各个领域的统计中，论文引证最多的文章有你和（John Hutchinson）教授的论文。据统计您的论文当年被引用达三百多次，目前已经达到七百多次。您能否给我们一些关于您的背景介绍？
This blog is on material behaviors under extreme loading.
It is well known that the algebra associated with edge dislocations can be forbidding. As Prof. Frank (of the Frank-Read source fame) noted once,
We report the direct molecular dynamics simulations for molecular ball bearings composed of fullerene molecules (C60 and C20) and multi-walled carbon nanotubes. The comparison of friction levels indicates that fullerene ball bearings have extremely low friction (with minimal frictional forces of 5.283×10-7 nN/atom and 6.768×10-7 nN/atom for C60 and C20 bearings) and energy dissipation (lowest dissipation per cycle of 0.013 meV/atom and 0.016 meV/atom for C60 and C20 bearings). A single fullerene inside the ball bearings exhibits various motion statuses of mixed translation and rotation. The influences of the shaft's distortion on the long-ranged potential energy and normal force are discussed. The phonic dissipation mechanism leads to a non-monotonic function between the friction and the load rate for the molecular bearings.
Del.icio.us is a social bookmarking web service. One might say, why do I need del.icio.us if I have bookmarking capabilities built right into my browser? Well, here are some reasons:
The discovery of a new material type, graphene and extremely thin platelets of graphite, was discussed in several articles from my research group published in 1999:
Lu XK, Huang H, Nemchuk N, and Ruoff RS, Patterning of highly oriented pyrolytic graphite by oxygen plasma etching, APPLIED PHYSICS LETTERS, 75, 193-195 (1999).
In the very beginning of 2007 I have four papers published or accepted (one is independent research and others are collaborated). All of them are the work done in my doctoral period. The topic is focusing on the enhancement of creep resistance of polymers by incorporating of nanofillers including particles and CNTs.
