CSIRO division of Earth Science and Resource Engineering is seeking a Senior Research Scientist in hydraulic fracturing/geomechanics. The position is located in Melbourne, Australia and the successful candidate will play a leading role in a world class hydraulic fracturing laboratory facility and in a hydraulic fracturing research team that integrates modelling with experimentation at laboratory and field scales.
These two papers have recently been published on-line in ZAMP:
The Nanobiophysics laboratory (Prof. Chaieb) in collaboration with the DNA replication laboratory (Prof. Hamdan) at the division of life science and engineering at KAUST invites
applications for immediate openings for a joint postdoctoral fellow
position between the two aforementioned lab although the primary position is at the Nanobophysics laboratory. The research is expected to
Bistable structures, exemplified
by the Venus flytrap and slap bracelets, can switch between different
functional shapes upon actuation, and have important applications in
mechanical/electro-mechanical devices ranging from bio-inspired robots to
deployable aeroplane wings. Despite numerous efforts in modeling such large
deformation of shell structures, the roles of mechanical and nonlinear geometric
effects on bistability remains elusive. Closely related, emerging challenges
include modeling the spontaneous curving and buckling of thin objects such as
A nanocomposite electrical generator composed of an array of zinc oxide nanowires is considered.
The electric potential distribution along zinc oxide nanowires is modeled using continuum
mechanics and Maxwell’s equations for the case of axial loading. A perturbation technique is used
for decoupling the constitutive equations. The governing differential equations are solved using a
finite difference method. It is shown that a gradient of electric potential exists along the axis of the
zinc oxide nanowires. Maximum and minimum values of electric potential exist at the extreme ends
along the nanowire length and have opposite signs. The positive and negative voltages are separated
Hi everybody. My name is Alexander Lyapin. I am a second year postgraduate student of Southern Federal University, Russia, Rostov-on-Don, and I am working in the field of poroelasticity. The topic of my future dissertation is "Dynamic problems of poroelastic enviroments". The main problems in my dissertation are fundamental solutions and enviroments with cavities of common arbitary shape. I use different methods such as boundary integral equations method Fourie transformation method and some other.
This paper reports the quantitative measurement of a full spectrum of mechanical properties of fivefold twinned silver (Ag) nanowires (NWs), including Young’s modulus, yield strength, and ultimate tensile strength. In-situ tensile testing of Ag NWs with diameters between 34 and 130 nm was carried out inside a scanning electron microscope (SEM). Young’s modulus, yield strength, and ultimate tensile strength all increased as the NW diameter decreased.
Dear Colleague:
You are cordially invited to attend Nanobrücken II: A Nanomechanical Testing Workshop, jointly presented by INM - Leibniz Institute for New Materials and Hysitron, Inc., with co-sponsorship from the JEOL company. This is the second workshop in the Nanobrücken series. The workshop's scope has been broadened, and the abstract submission deadline is now February 19, 2012.
