An assessment of biomedical CoCrMo alloy fabricated by direct metal laser sinte...

CoCrMo alloys have been used for several decades in implantable devices due to their favourable mechanical properties, low wear rate in addition to good biocompatibility and high corrosion resistance. These alloys are conventionally produced via casting and/or forging route, however additive manufacturing techniques being recently employed in their fabrication. In this work, CoCrMo samples were produced by dire...

Mechanical and phase transformation behaviour of biomedical Co-Cr-Mo alloy fabr...

Biomedical cobalt-chromium-molybdenum (Co-Cr-Mo) alloys have been used in the cast or wrought form as prosthetic implant materials for more than five decades. Recently, additive manufacturing techniques are employed to produce parts directly from metal precursor powder with a composition suitable for biomedical applications. In the work present, we examine both mechanical behaviour and γ→ε phase transformation ...

Polyurethane fibrous membranes tailored by rotary jet spinning for tissue engin...

Made available in DSpace on 2022-04-28T19:27:45Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-03-15; Polymeric membranes have gained popularity as fibrous structures for tissue regeneration. This research focuses on the rotary jet spinning (RJS) process combined with a polymer as a strategy for designing membranes. To this end, RJS-polyurethane (RJS-PU) membranes with different microstructures were pro...

Phosphorus sorption, desorption and resorption by soils of the Brazilian Cerrad...

Oxisols of the Brazilian Cerrado are highly weathered phosphorus deficient soils, on which eucalypt is increasingly being grown as a source of carbon and energy for steel manufacturing. Phosphorus (P) fertilization is a necessary practice to assure adequate eucalypt production; therefore, an understanding of cycling by inorganic soil P should lead to efficient P management and more accurate modeling of P bioava...

Influence of sugarcane bagasse variability on sugar recovery for cellulosic eth...

Made available in DSpace on 2018-12-11T17:12:03Z (GMT). No. of bitstreams: 0 Previous issue date: 2017-01-01; In the context of cellulosic ethanol production, special attention must be given to the raw material, as it affects final product yield. As observed for sugarcane, bagasse variations may derive from several elements, for instance edaphoclimatic factors, seasonality, maturation stage and harvesting techn...
