Johnson Matthey Technology Review

Part II presents the results which show that HA coatings significantly enhance MSC proliferation by 13% compared to the titanium alloy base, while titanium coatings also exhibit an 11% increase. Porosity inversely affects CP-Ti’s elasticity. Coatings with lower porosity demonstrate better corrosion resistance. HA coatings promote osteogenic activity and angiogenesis, which is crucial for implant integration.

The mineralogical properties and distribution of information established in saprolite from Indonesia were investigated using X-ray diffraction (XRD), X-ray fluorescence (XRF), scanning electron microscopy energy dispersion spectroscopy (SEM–EDS) and differential thermal analysis (DTA) measurements. The findings suggest that laterite ore has a complex inner core. The percentages of nickel, iron, magnesium, aluminium and silicon in saprolite are 1.82 wt%, 30.47 wt%, 10–20 wt%, 4.86 wt% and 8.1 wt%. Saprolite has 53.1 wt% iron oxide/oxyhydroxide, 38.3 wt% lizardite and 8.7 wt% silicate. According to DTA, saprolite undergoes a phase shift from goethite to haematite at low temperatures (200–300°C). This is a suitable phase to optimise nickel diffusion in iron. Furthermore, the thermal upgrading approach was utilised for this saprolite.

Preliminary Characterisation of Thermal Upgrading of Nickel from Saprolite via Selective Reduction

通过选择性还原法对残积镍矿进行热升级的初步表征

The pursuit of sustainable energy sources on a worldwide scale is a crucial and pressing matter, with the United Nations Sustainable Development Goals (UNSDGs) offering a comprehensive framework for properly addressing this challenge. This two-part paper provides an overview of the various technologies now available for the process of biomass gasification. Compared to other renewable energy sources, which have undergone significant technological advancements in recent years, the field of biomass conversion is still relatively new. Keeping up with the newest breakthroughs becomes increasingly crucial as new conversion techniques are rapidly being created. In the thermochemical conversion process called ‘biomass gasification’, biomass solid source materials are degraded or incompletely burned in an oxygen-free or oxygen-deficient high-temperature atmosphere, resulting in the production of biomass gas. Part I delves into different biomass gasification techniques, including upstream, gasification and downstream processes, highlighting their importance in transforming biomass into clean and combustible gases.

The study of copper on zinc oxide surfaces is a topic of ongoing research due to the importance of copper as a promoter in the low-temperature synthesis of methanol, the water-gas shift process and methanol steam reforming. The role of zinc oxide in supporting the stabilisation of the copper atoms and promoting the CO 2 hydrogenation reaction is multifaceted and involves a range of physical and chemical factors. In this work, we used density functional theory (DFT) calculations to investigate the copper adsorption on zinc oxide surfaces on different sites. Bader charge analysis, adsorption energy and phonon inelastic neutron scattering (INS) associated with most stable systems were calculated and compared with previous theoretical and experimental results. We found that atomic copper adsorption on hollow site of ZnO(111) is the most stable and favourable site for copper adsorption compared to other zinc oxide surfaces. This is due to the strong metal-oxygen interaction between copper and the zinc oxide surface. We concluded that further studies are needed to investigate the catalytic activity of this catalyst under realistic reaction conditions with realistic models of copper supported on zinc oxide.

Part II of this review focuses on methodologies and protocols employed in biomass gasification, recognising its pivotal role in sustainable energy generation. Additionally, the article discusses the challenges associated with gasification technology, such as tar formation, biomass heterogeneity and uneven biomass supply in different seasons. It emphasises the need for further research and infrastructure development to overcome these barriers and facilitate the efficient distribution and commercialisation of biomass gasification technology. Overall, the scope of the article extends to providing insights into the status, challenges and future prospects of biomass gasification for achieving sustainable energy goals.

This is Part II of a comprehensive review analysing recent studies on various high entropy alloys (HEAs). Here, we present their magnetic and electrical properties, corrosion resistance, wear behaviour and different applications. Remaining challenges and perspectives are summarised. The anticipated findings of this two-part review are a milestone for future investigations on the production and analysis of HEAs. The discoveries hold great value for researchers, designers and manufacturers working in this field, as they offer valuable knowledge regarding the characteristics and possible uses of HEAs. Consequently, these findings lay the groundwork for further exploration in this promising field of materials science.
