The need for highly performing vascular biomaterials is rapidly increasing with the ageing of population. Vascular diseases are the primary cause of death in the world and at least 1 million patients undergo to surgical operation for prosthesis implantation each year worldwide to face cardiovascular occlusive diseases, aneurysms and acute renal failures. As the major problem still resides in an interfacial...
As the demand for new thermal technologies and materials has been increasing over the years to provide thermal solutions to the next generation of power electronics, microprocessors and high-power optical systems also thermal characterisation methods have to keep up with the pace of this development with respect to resolution and accuracy. We have developed both bulk and interface technologies to...
Passivation of interfaces corresponding to the nanoposts' sidewalls in InP-based intersubband quantum-box (IQB) lasers has resulted in interfacial-state densities < 1011/cm2. High-quality regrowths of semi-insulating InP around dry-etched, passivated, 40 nm-diameter nanoposts were realized.
There are currently no orthopedic materials which are made to prevent either the occurrence or reoccurrence of cancer. Due to the above, the objective of this study was to create a new biomaterial which can both restore bone and, at the same time, prevent cancer growth at the implant interface. In the present study, three types of surfaces with different surface densities were prepared. Competitive...
As the demand for new thermal technologies and materials has been increasing over the years to provide thermal solutions to the next generation of power electronics, microprocessors and high-power optical systems also thermal characterisation methods have to keep up with the pace of this development with respect to resolution and accuracy. Within the EU-funded project ldquoNanopackrdquo we have developed...
Micro and nanosystems are the completed devices that combine into one sensor, electronic, and mechanical parts. Realization of the mechanical interaction between nano-, micro-, and macro world is the limiting factor for such a complex system.
Silicene, a monolayer of silicon atoms packed into a two-dimensional honeycomb lattice is the challenging hypothetical reflection in the silicon realm of graphene, a one-atom thick graphite sheet, presently the hottest new material in condensed matter physics and nanotechnology. If existing, it would also reveal a cornucopia of new physics and potential applications. Here, we reveal the catalytic...
We have demonstrated direct nanoscale transfer printing of PdAu lines from a hard mold onto a hard substrate at room-temperature without employing any flexible buffer layers or organic adhesion promoters or release agent layers. The molds used in these experiments were GaAs/AlGaAs sandwich structures fabricated by molecular-beam epitaxy that we cleaved and selectively etched afterwards in order to...
Atomic layer deposition (ALD) is emerging as a promising nanotechnology for manufacturing dielectrics and insulators on microelectronics devices. Its environmental performance has to be characterized at this early development stage to achieve sustainable manufacturing in the future. In this paper, we report our environmental performance characterization studies on ALD technology through material flow...
We have investigated uniform carbon nanotube (CNT) dispersion in a solution and fabrication of CNT thin films on solid surfaces. To prevent bundle formation, we have examined surface modification of both the CNT surfaces and the substrate surfaces. To enhance the interaction between surfaces of the substrate and the CNTs, the substrate surfaces were made hydrophobic, because CNTs are generally hydrophobic...
We report thermoelectric characterization of Bi2-xSbxTe3 (x = 0.5, 1.0, and 1.5) synthesized by a solvothermal method using DMF as solvent. For Bi2Te3, the size of the edge and thickness of the hexagonal nanoplatelets are 200-250 nm and 20-25 nm, respectively. Bi2Te3 nanosheets appear to grow epitaxially from the surface of the Te tubes, which forms in the first step and acts as the template for the...
