6Thermal activation of Ti_((1-x))Au_((x))thin films with enhanced hardness and biocompatibility显示文摘The lifetime of orthopaedic implants can be extended by coating the softer Ti6Al4V alloy with harder biocompatible thin films.In this work,thin films of Ti_((1-x))Au_((x))are grown on Ti_(6)Al_(4)V and glass substrates by magnetron sputtering in the entire x=0-1 range,before their key biomechanical properties are performance tuned by thermal activation.For the first time,we explore the effect of in-situ substrate heating versus ex-situ post-deposition heat-treatment,on development of mechanical and biocompatibility performance in Ti-Au films.A~250% increase in hardness is achieved for Ti-Au films compared to bulk Ti6Al4V and a~40%improvement from 8.8 GPa as-grown to 11.9 and 12.3 GPa with in-situ and ex-situ heat-treatment respectively,is corelated to changes in structural,morphological and chemical properties,providing insights into the origins of super-hardness in the Ti rich regions of these materials.X-ray diffraction reveals that as-grown films are in nanocrystalline states of Ti-Au intermetallic phases and thermal activation leads to emergence of mechanically hard Ti-Au intermetallics,with films prepared by in-situ substrate heating having enhanced crystalline quality.Surface morphology images show clear changes in grain size,shape and surface roughness following thermal activation,while elemental analysis reveals that in-situ substrate heating is better for development of oxide free Ti3Auβ-phases.All tested Ti-Au films are non-cytotoxic against L929 mouse fibroblast cells,while extremely low leached ion concentrations confirm their biocompatibility.With peak hardness performance tuned to>12 GPa and excellent biocompatibility,Ti-Au films have potential as a future coating technology for load bearing medical implants.Cecil Cherian Lukose Ioannis Anestopoulos Theodora Mantso Leon Bowen Mihalis I.Panayiotidis Martin Birkett 2022Bioactive Materials2022,7,9:0
7Bacterial direct-fed microbials fail to reduce methane emissions in primiparous lactating dairy cows显示文摘Direct-fed microbials(DFM) are considered as a promising technique to improve animal productivity without affecting animal health or harming the environment.The potential of three bacterial DFM to reduce methane(CH4)emissions,modulate ruminal fermentation,milk production and composition of primiparous dairy cows was examined in this study.As previous reports have shown that DFM respond differently to different diets,two contrasting diets were used in this study.Eight lactating primiparous cows were randomly divided into two groups that were fed a corn silage-based,high-starch diet(HSD) or a grass silage-based,high-fiber diet(HFD).Cows in each dietary group were randomly assigned to four treatments in a 4 × 4 Latin square design.The bacterial DFM used were selected for their proven CH4-reducing effect in vitro.Treatments included control(without DFM) and 3 DFM treatments: Propionibacterium freudenreichii 53-W(2.9 × 10^10 colony forming units(CFU)/cow per day),Lactobacillus pentosus D31(3.6 × 10^11 CFU/cow per day) and Lactobacillus bulgaricus D1(4.6 × 10^10 CFU/cow per day).Each experimental period included 4 weeks of treatment and 1 week of wash-out,with measures performed in the fourth week of the treatment period.Enteric CH4 emissions were measured during 3 consecutive days using respiration chambers.Rumen samples were collected for ruminal fermentation parameters and quantitative microbial analyses.Milk samples were collected for composition analysis.Body weight of cows were recorded at the end of each treatment period.Irrespective of diet,no mitigating effect of DFM was observed on CH4 emissions in dairy cows.In contrast,Propionibacterium increased CH4 intensity by 27%(g CH4/kg milk) in cows fed HSD.There was no effect of DFM on other fermentation parameters and on bacterial,archaeal and protozoal numbers.Similarly,the effect of DFM on milk fatty acid composition was negligible.Propionibacterium and L.pentosus DFM tended to increase body weight gain with HSD.We conclude that,contrary to the effect previously observed in vitro,bacterial DFM Propionibacterium freudenreichii 53-W,Lactobacillus pentosus D31 and Lactobacillus bulgaricus D1 did not alter ruminal fermentation and failed to reduce CH4 emissions in lactating primiparous cows fed high-starch or high-fiber diets.Jeyamalar Jeyanathan Cecile Martin Maguy Eugene Anne Ferlay Milka Popova Diego P.Morgavi 2019Journal of Animal Science and Biotechnology2019,10,3:0
