Composite bone graft of CaO-MgO-SiO glass-ceramics and CaSO ceramics for boosting bone formation rate.

This study develops a composite bone graft of CaO-MgO-SiO glass-ceramic and CaSO [abbreviated as (CMS)(CS)] the sponge replication technique with weight fractions of = 0, 1, 1.5, 2, and 3. The (CMS)(CS) composite displays a superior degradability and, a suitable compressive strength of ∼3 MPa, and excellent cell proliferation and differentiation.

Enhanced mechanical and biological performances of CaO-MgO-SiO glass-ceramics via the modulation of glass and ceramic phases.

This work reports a new CaO-MgO-SiO (CMS) bioactive glass-ceramic, using ZrO as a nucleus to modulate the ratios of glass and ceramic phases as a function of sintering temperature. Mg-rich bioactive CMS glass-ceramics exhibit advantages regarding mechanical strength (flexural strength ~190 MPa and compressive strength ~555 MPa), in-vitro and in-vivo biocompatibilities, and bone ingrowth. The high mechanical strengths could be attributed to the CaMgSiO glass-ceramic and lower porosity.

Control of Silver Diffusion in Low-Temperature Co-Fired Diopside Glass-Ceramic Microwave Dielectrics.

Electrode material for low-temperature co-fired diopside glass-ceramic used for microwave dielectrics was investigated in the present work. Diffusion of silver from the electrode to diopside glass-ceramics degrades the performance of the microwave dielectrics. Two approaches were adopted to resolve the problem of silver diffusion.

Fabrication of ordered metallic glass nanotube arrays for label-free biosensing with diffractive reflectance.

In this study, a photoresist template with well-defined contact hole array was fabricated, to which radio frequency magnetron sputtering process was then applied to deposit an alloyed ZrCuAlNi target, and finally resulted in ordered metallic glass nanotube (MGNT) arrays after removal of the photoresist template. The thickness of the MGNT walls increased from 98 to 126nm upon increasing the deposition time from 225 to 675s. The wall thickness of the MGNT arrays also increased while the dimensions of MGNT reduced under the same deposition condition.
