Acredita-se que sinais elétricos endógenos afetem remodelamento, metabolismo, reparo e crescimento ósseos. Existe uma ampla literatura que trata do efeito de sinais elétricos externos sobre as respostas de síntese, mitogênese e proliferação e

Using electron beam gun PVD system, the thin film with multiple alternative layers of SiO 2 + Ag (300 nm)/SiO 2 (10–60 nm) was deposited on silica substrate. Annealing test was undertaken for optical absorption analysis. The annealing agglomerated

We have used implanted silver ions near the surface of Glassy Polymeric Carbon (GPC) to completely inhibit cell attachment and adhesion to GPC. The effect improves the safety and function of the GPC heart valve exposed to the blood stream. The streng

We report the design of an ion beam bombardment chamber that enables the controlled fabrication of nanometer-sized holes in solid-state materials. The instrument employs a beam of MeV gold ions that impinges on a polymer membrane whose properties are

In order to keep the stoichiometry of Bi 2 Te 3 and Sb 2 Te 3 , with the purpose of preserving the electrical and thermal conductivity advantage of the layered structure of bulk Bi 2 Te 3 and Sb 2 Te 3 in each period of the superlattice, magnetron sp

Ion beam bombardment provides a unique way of material modification by inducing a high degree of localized electronic excitation. The ion track, or affected volume along the ion path through the material is related to the total damage and possible st

We made n-type nano-scale thin film thermoelectric (TE) devices that consist of multiple periodic layers of Si 1− x Ge x /Si. The period is about 10 nm. The structure was modified by 5 MeV Si ion bombardment that formed a nano-scale cluster structu

Biocompatible Glassy Polymeric Carbon (GPC) is used for artificial heart valves and in other biomedical applications. Although it is ideally suited for implants in the blood stream, tissue that normally forms around the moving parts of a GPC heart va
