Journal Club Theme of June 2013: Biological Ferroelectricity: from Speculation to Reality
Submitted by jiangyuli on Fri, 2013-05-31 06:05.When a dielectric is placed in an electric field, it becomes polarized - positive and negative charges are separated, producing polarization defined as dipole moment per unit volume. Simultaneously, the dielectric experiences electrostrictive strain that is quadratic to polarization, though it is usually negligibly small. However, if the dielectric has no symmetry center, relatively large piezoelectric strain proportional to the electric field is also possible. Among 21 crystalline classes without a symmetry center, 20 of them are piezoelectric, within which 10 of them possess a unique polar axis that is spontaneously polarized, referred to as pyroelectric, whose spontaneous polarization varies with temperature. If such spontaneous polarization can be reversed by an external electric field, then the pyroelectric is also ferroelectric, and ferroelectricity refers to switching of spontaneous polarization in pyroelectric.

1st International Symposium on Energy Challenges and Mechanics (首届能源挑战与力学国际研讨会)
Submitted by Henry Tan on Mon, 2013-06-10 08:15.Introduction: This symposium is about energy challenges and roles of mechanics as a means for seeking solutions, involving multiple disciplines in technology, science and management. The venue of the symposium is in Aberdeen, Scotland, the Energy Capital of Europe. Since Watt, a Scottish, invented the steam engine, human civilization relies more and more on energy supply. The re-rise as an international superpower and the global energy crisis are challenging China and the world. Many Chinese engineers and mechanicians are taking leading roles in international conferences, so we adopt English/Chinese bilingual for communication.

PhD Studentship@University of Southampton, UK - Wet Adhesive Poro-Viscoelastic Contact Along Human Skin Surface
Submitted by wwfchong on Fri, 2013-06-07 07:44.
Skin, the largest organ of the human body, acts as a
multi-functional biophysical interface to the external environment. The serial
interfacial phenomena along the skin/environment conjunction, particularly when
interacting with cosmetic and consumer goods (e.g. razor and shave preparation)
is determined by the interplay between the chemical structure and arrangement
of stratum corneum lipids,
environmental factors (e.g. hydration level) and also the physical
characteristics of skin surface relief. Therefore, the chemical and biophysical
properties of the stratum corneum
need to be considered jointly to approach the complexity of skin tribo-physics.
These technical challenges present outstanding opportunities for high quality

PhD Studentship@University of Southampton,UK-The Design of Lubricant-Surface Interaction for Reduced Boundary Friction and Wear
Submitted by wwfchong on Fri, 2013-06-07 07:40.
Mechanical losses account for 15% of total energy loss in an
IC engine where 45% of these losses result from friction of piston-ring
assembly. An increase in mechanical efficiency of 10% could lead to improved
fuel consumption of 1.5%. Taking into account the large number of vehicles on
road (30 million in the UK in 2010 according to the Society of Motor
Manufacturers and Traders) and fuel
consumption of 12.5 miles/litre, the potential fuel saving would accrue to
approximated £647 million/annum, which is substantial to the country's economy.
Therefore, the advantage in improving mechanical efficiency of IC engines and
also other machines is self-evident.

Crack thickness
Submitted by Konstantin Volokh on Thu, 2013-05-30 12:41.
Macroscopic
cracks do not appear as a result of an ideal separation of two adjacent atomic
layers. Just the opposite, cracks appear as a result of the development of
multiple micro-cracks triggered by the massive breakage of atomic bonds. The microcracking
and the bond breakage are not confined to two neighbor atomic planes: the
process involves thousands atomic planes within the representative characteristic
volume of size h. This size defines the width (not the lenth) of the damage
localization zone and it can be called the crack thickness. The knowledge of
