Surface roughness evolution
With a shallow chemical etching the roughness with spatial frequency below a critical value grows while the roughness of higher frequency decays.

If degrees were not a discriminator for hiring, would lying about degrees still be a serious offense?
I'm saddened by the recent resignation of Marilee Jones, the dean of admissions at MIT. By all accounts she has been an excellent employee, but she lied about her degrees when she first applied for an entry-level job 28 years ago.
I do think that lying is wrong, and I can't blame the administration of MIT for taking actions. However, I'm uneasy about the general practice of employment.
NSF Proposal Writing Workshop
Subject: NSF Proposal Writing Workshop ( August 22-23, 2007 - Alaska)
Sponsored by NSF, a Proposal Writing Workshop will be held on August 22-23, 2007, at University of Alaska-Fairbanks. The workshop mainly aims to provide future proposal submitters (in all disciplines funded by NSF) with knowledge and tools to write good proposals, proposal review experience, and it will enable interactions with NSF program directors and recent NSF awardees. The event is targeted at an EPSCoR state, Alaska. However, the workshop is open to participants from other states as space permits.
Adhesion in viscoelastic contacts
Yesterday I had the distinct pleasure of seeing a mechanics seminar delivered "tag-team" by Ken Johnson and Jim Greenwood. (I know several people have thought I was a bit mad for jumping "across the pond" but there are really some amazing benefits of being part of the Cambridge Engineering faculty!)
Going beyond 2D Neumann-Mullins (or, what is popularly known as, solving the beer froth structure)
Introduction
The blogosphere is abuzz with the latest report of the generalisation of the von Neumann-Mullins grain growth relation to 3 (and N) dimensions by MacPherson and Srolovitz (As an interesting aside, almost all the reports say mathematical structure of beer foam structure resolved, or words to that effect --hence, I also decided to join the bandwagon on that one). I heard Prof. Srolovitz describe the work in a seminar nearly six months ago. Based on my notes of the talk, I would like the explain their work in this post. Curvature in the following refers to mean curvature (and not Gaussian).
The 8th International Conference on Electronics Packaging Technology (ICEPT)
The 8th International Conference on Electronics Packaging Technology (ICEPT), organized and supported by authoritative academic organizations and leading industries, will be held at Shanghai, China from August 14 -17, 2007.
Adhesion study for polymer/polymer interface or polymer/metal interface in microscopic level
Is there any study on hierarchical structures for polymer/polymer interface or polymer/metal interface? and link the polymer molecular structure with fracture or adhesion study? What is the role of mechanical bonding compared to physical and chemical bonding?
Micropolar material constants
Can someone help me to give the numerical values for micropolar elastic solids and micropolar fluids so that i can study the behaviour of such materials numericaly? Also
Microcantilever operated in liquid environment for in-vitro biomolecular detection
We have recently reported the piezoelectric thick film microcantilever, which enables the in-situ real-time detection of the protein related to disease (e.g. C reactive protein) in liquid environment. This work was published at APL (click here).
