While biomedical devices such as prosthetic heart valves, heart-assist devices, oxygenators, vascular grafts and hemodialysis systems can help to save or significantly extend lives, these same devices also can damage the blood cells which travel through them. Severe consequences can result when blood cells are damaged or broken down, said Marina Kameneva, Ph.D., research associate professor of surgery at the University of Pittsburgh School of Medicine.
Dr. Kameneva will discuss the issue in a plenary lecture on "hemorheological aspects of flow induced blood trauma in artificial organs" on Sept. 26 during a joint meeting of the 11th International Congress of Biorheology and the 4th International Conference on Clinical Hemorheology in Antalya, Turkey. Rheology is the science of the deformation and flow of matter.
"Biomedical devices are widely used to repair or replace a number of cardiovascular system elements," said Dr. Kameneva, a scientist at the University of Pittsburghs McGowan Institute for Regenerative Medicine who is one of the few working worldwide whose research focuses on fluid dynamics and artificial blood products. "The successful functioning of these devices strongly depends on the way they disturb blood."

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
