The effect of porosity on the stiffness and fracture energy of brittle organosilicates
Integrating porous low-permittivity dielectrics into Cu metallization is one of the strategies to reduce power consumption, signal propagation delays, and crosstalk between interconnects for the next generation of integrated circuits. However, the porosity and pore structure of these low-k dielectric materials also strongly affects other important material properties besides their dielectric constant.

iMechanica back on service
Dear fellow iMechanicians:
After some technical problems over the past weekend, iMechanica is now back on full service. We apologize for any inconvenience this may cause and thank for your patience.
We are particularly grateful to Ms. Lesley Lam in OIT of Harvard School of Engineering and Applied Sciences for her prompt fix of the problem.
EM 388F Term Paper: Theory and analysis tech for the use of a DCB specimen for determining the toughness of PC-3 Prostate Cancer
A double cantilever beam (DCB)
specimen is created by affixing the two halves together using a bi-layer of
PC-3 prostate cancer cells. The specimen is pinned at a bottom corner, and the
upper corner on the same end is displaced with the force-displacement profile
being recorded. This upper corner is displaced until the crack, a portion of
the specimen where cell grown has been selectively inhibited, propagates
through the cell layer. The critical value of force at which the crack
propagates through the cell layer is used, in conjunction with the initial
crack length, to determine the toughness via the compliance-energy method (Ripling, et al. 1971). A method for performing a FE analysis of the
Deformation and Fracture of Functional Ferromagetics
Prof.D.N. Fang and his collaborators (Prof. Y.P. Wan, Prof. X. Feng and Prof. A.K. Soh) work on the functional materials, such as ferroelectric and ferromagnetic materials. Recently, he published a review article which presents an overview of recent progress on magnetomechanical deformation and fracture of ferromagnetic materials.
iMechanica server error
Many of you must have noticed that the iMechanica server is unstable today. Apparently posts that have comments are inaccessible. The IT office has been altered, but today is Saturday. Meanwhile you can read comments by clicking "comments at a glance" on the right side of iMechanica. Toddler iMechanica is having growing pain. She apologizes for your inconvenience.
PROPOSALS FOR IMECHANICA
Hello imechanica users: I launch a few ideas. Can we improve imechanica stealing ideas from successful web systems like google, amazon, wikipedia, myspace, youtube? Taking the best of the various worlds to improve our imechanica?
