Boosting CO_(2) hydrogenation to high-value olefins with highly stable performance over Ba and Na co-modified Fe catalyst

CO_(2)hydrogenation has been considered to be a highly promising route for the production of high-value olefins(HVOs)while also mitigating CO_(2)emissions.However,it is challenging to achieve high selectivity and maintain stable performance for HVOs(ethylene,propylene,and linear a-olefins)over a prolonged reaction time due to the difficulty in precise control of carbon coupling and rapid catalyst deactivation.Herein,we present a selective Ba and Na co-modified Fe catalyst enriched with Fe_(5)C_(2)and Fe_(3)C active sites that can boost HVO synthesis with up to 66.1%selectivity at an average CO_(2)conversion of 38%for over 500 h.Compared to traditional NaFe catalyst,the combined effect of Ba and Na additives in the NaBaFe-0.5 catalyst suppressed excess oxidation of FeCxsites by H_(2)O.The absence of Fe3O4phase in the spent NaBaFe-0.5 catalyst reflects the stabilization effect of the co-modifiers on the FeCxsites.This study provides a strategy to design Fe-based catalysts that can be scaled up for the stable synthesis of HVOs from CO_(2)hydrogenation.

Current State of Affairs with Regard to Continuing Medical Education for Technicians in Radiology in Francophone West Africa

Background: This study aimed to determine the level of continuing medical education (CME) of medical imaging technicians in French-speaking West Africa. Materials and methods: This opinion survey was administered to radiology technicians in French-speaking West Africa from 1st June to 31st October 2020, i.e. over a period of 5 months concerning their level of CME and their need for CME. Results: Out of 100 technicians, 69% were men. The mean age was 40 years, with extremes ranging from age 23 to age 57. The majority of technicians (64%) worked in the public sector and 78% had work experience of less than 11 years. Most technicians were holders of a Bachelor’s degree (73%). The types of CMEs they knew were congresses, seminars, and modular training in 46% of the cases. The most available CMEs were seminars (63%). All technicians agreed on the need for CME and 96% said it had an impact on the delivery of radiology services. Technicians who had received CME at least once represented 61%. For 90% of technicians, the specific CME sought was management in radiology (33.33%) and radiation protection (25.81%). Conclusion: The need for CME is increasingly indisputable to radiology technicians in French-speaking West Africa;however, it remains a luxury for them, due to its scarcity and its high cost.

Genetic Bioengineering in the Achievement of Algae Biofuels and High-Value Bio-products

The dependence to fossil fuels has increased the amount of greenhouse gases in the atmosphere.That is why,the production of renewable and sustainable biofuels has gained a long-term importance for both scientific and political necessities.In this context,algae are promising in terms of alternative biofuels resources.For this reason,intensive scientific researches have been carried out in recent years on providing optimum efficiency in this regard.Bioengineering is a discipline that applies engineering principles of design and analysis to biological systems and biomedical technologies.Examples of bioengineering research include bacteria or microalgae engineered to produce valuable bioactive chemicals.Microalgae by target gene modification may serve as a promising source for the production of biofuels and bio-based chemicals.A lot of research has been carried out by applying microalgae genomic editing technique with the aim to produce numerous biotechnological products.Some successful previously reported research and production activities are still underway in this area.However,in order to produce the desired products efficiently with manipulated microalgae biorefinery,there is a need to overcome the problem of low biomass production despite high production costs.The aim of this work is to give special attention to the rich potential content of microalgae and to provide information on algal genetic manipulations to increase products by bioengineering methods.

Profile of Polycyclic Aromatic Hydrocarbons in Soil Environment around Selected Auto-Technicians’ Workshop in ObioAkpor, Rivers State Nigeria

A study on the storage and disposal practices of spent oil from Automobile workshops in ObioAkpor Local Government Area of Rivers state was conducted to determine the levels of polycyclic aromatic hydrocarbons (PAHs) in soil samples. Questionnaire was administered and a total of 150 autotechnicians were sampled. Taro Yamani formula was used to determine the sample size. Soil samples were collected at depths of 0 - 15 cm from 8 randomly selected sites and analyzed for PAH. Control consisted of a similar soil with no history of spent oil-contamination. Results showed that autotechnicians had little or no formal education. Only 51% of respondents had secondary/technical education. 94% of the study population disposed of their generated spent oil in various types of containers before disposal. 94% disposed of their spent oil by selling. 60% of the autotechnicians were not aware that spent oil was hazardous. More so, 76% were not aware that spent oil could be recycled. Analysis of soil samples showed that mean concentration of PAH was lower than the DPR standard in all locations. Control values did not show any consistent pattern when compared with the test values in all locations. Soil contamination by PAH in the study area ranged from minor to severe. The automobile workshops pose potential sources of PAH pollution. The study recommends enactment and enforcement of legislations to control the management of spent oil.

Establishing Standardized Biomedical Laboratory Technician Education for the Development of Biotech no logy Research in China
