Microstructure Design of Steel‐Spinel Composites via Spark Plasma Sintering Process

Advanced Engineering Materials, EarlyView.
This study illustrates how spark plasma sintering at reduced oxygen partial pressure enables controlled formation of steel‐spinel composites through tailored redox reactions and cation exchange. Comparison of the MgO–Fe2O3, steel–(MgO+Cr2O3), and steel–(MgO+Fe2O3) systems shows how oxygen activity and interface chemistry govern spinel formation, phase ...

Persulfate–derived porous wollastonite granules for accelerated CO2 mineralization and suitability for aggregate applications

Carbon Capture Science & Technology
Mineral carbonation technology is a promising solution for CO2 capture and utilization. To achieve large scale application of the technology, the challenges related to CO2 diffusion and passivation by carbonate precipitation must be overcome.

Evolution of respiration rate, internal CO₂ or O₂ and resistance to gas diffusion of anaerobic exposed and waxed 'Miho' satsuma fruits during market life [PDF]

, 1998
'Miho' satsumas received an anaerobic treatment with N2 or CO2 for 24 hr at 20°C before being waxed with shellac and transferred to 20°C for 30 days, in order to measure respiration rate, internal gas evolution (CO2 and O2) and peel resistance to CO2 ...

Production of MgO/TiC Composites From MgO‐C Recyclates Using Spark Plasma Sintering

Advanced Engineering Materials, EarlyView.
Using the spark plasma sintering technique, MgO/TiC composites are manufactured from recycled MgO‐C refractories stemming from the steel production that were mixed with titanium powder. This article shows, how the size of the Ti grains and their distribution in the powder mixture affect the local carbon concentration in TiC.

Copper Nanocrystallization in Anodic Oxide Films of Ti–Cu‐Based Bulk Metallic Glass and Its Effect on the Corrosion Resistance and Cytocompatibility

Advanced Engineering Materials, EarlyView.
Viktoriia Shtefan, Thorgund Nemec, Ute Hempel, Annett Gebert and coworkers demonstrate that anodic treatment of Ti–Cu‐based metallic glass in a nontoxic pyrophosphate electrolyte forms a protective bilayered Ti/Zr‐oxide film enriched with Cu nanocrystals.

Evaluation of CO2 storage properties and mobility through NMR technique in post-grafting synthetized organically functionalized porous silica

Journal of CO2 Utilization
Functionalized porous silica materials were synthesized in alkaline conditions by post-grafting method using hexadecyltrimethylammonium bromide (CTAB) as templating agent, tetraethyl orthosilicate (TEOS) as silica precursors and trialkoxysilanes ...

Direct Metal Deposition of Graphene–Ti28Nb35.4Zr Matrix Composites With Enhanced Mechanical, Corrosion, and Biocompatibility Properties for Bone Implants

Advanced Engineering Materials, EarlyView.
Graphene nanoplatelet (0.1 wt.%) reinforcement significantly enhances the performance of β Ti‐28Nb‐35.4Zr alloy. Grain refinement, reduced water contact angle, and improved surface characteristics promote osteoblast adhesion and complete surface coverage after 7 days.
