In Senegal, artisanal vegetable oils trade is developing and Balanites aegyptiaca (desert date) as well as Sesamum indicum (sesame) are popular vegetal species. Present study focused on oils obtained from these two plants seeds. These oils have various applications such as for dietary and cosmetic purposes. Sampling carried out in Dakar region allowed collection of five oil samples for each specie, mainly in different districts shops or craft fairs. Their peroxide, acid, iodine and saponification values as well as volatile matter, tocopherols and vitamin A contents have been determined through reference methods described by International Organization for Standardization (ISO) or French Standardization Association (AFNOR). Obtained experimental data were compared with Codex Alimentarius standard and/or literature, since some parameters are not subject to specific regulation. Balanites aegyptiaca and Sesamum indicum oil samples showed an orange-yellow or pale yellow coloration. Only one desert date oil sample had an adequate peroxide value while two from sesame were not compliant. Iodine values for B. aegyptiaca samples were closed to a result previously described by peer researchers for an oil produced from seeds harvested in Senegal but out of Codex specification range for sesame oils. All ten samples had a suitable acidity, widely below maximum value of 4.0 mg KOH/g. Two sesame oil samples had correct saponification value. Among ten oil samples collected, eight showed a volatile matter content exceeding standard. Vitamin A had not been detected in any sample. Desert date oils tocopherols content were comprised between 975.38 and 1141.36 mg/kg and S. indicum samples met the standard indicating a tocopherols level in the range [330 -1010 mg/kg]. Present study results are not all conclusive and reinforce reservations about commercially available artisanal oils quality. However, literature review allows to state that oils physico-chemical properties and nutrient content vary greatly.

In this study, AISI 2205 duplex stainless steel was joined with laser welding. Base material and laser-welded samples were kept in simulated body fluid (SBF) for 1, 3, 7, 14, 21, and 28 days. This research investigated microstructure, hydroxyapatite (HA) structure formed on surfaces, surface topography, and corrosion properties of samples which were kept in SBF. Characterization studies were performed by using microhardness, optical microscope, macroscope, SEM-EDS, XRD, and atomic force microscope. According to results, it was found out that HA accumulation was higher on base material surface when compared to weld seam surface, and also calcium-deficient carbonate HA structure with low crystallinity was observed on all surfaces. Very low corrosion rates due to very low weight losses were detected in all samples kept in SBF. The results showed us that heat input changes had an important effect on surface roughness values (R a ), apatite morphology on weld seam surfaces, and corrosion behaviors. Overall, it is considered that laser-welded duplex stainless steel can be used as an implant material depending on surface characterization and corrosion behaviors.

“…Biofuels are generally referred to as liquid or gaseous fuels that are produced from renewable sources [5], which are typically generated from biological material or living organisms, such as plants, animal by-products, or microorganisms [6]. In the past Based on various physicochemical properties of the catalysts, both acid and base catalysts can be classified as homogeneous, heterogeneous or enzymatic catalysts [32][33][34]. Homogeneous acid and base catalysts such as H2SO4, HCl, NaOH and KOH are the most common homogeneous catalysts used in esterification and transesterification reactions [35].…”

Progress on Modified Calcium Oxide Derived Waste-Shell Catalysts for Biodiesel Production

et al. 2021

The dwindling of global petroleum deposits and worsening environmental issues have triggered researchers to find an alternative energy such as biodiesel. Biodiesel can be produced via transesterification of vegetable oil or animal fat with alcohol in the presence of a catalyst. A heterogeneous catalyst at an economical price has been studied widely for biodiesel production. It was noted that various types of natural waste shell are a potential calcium resource for generation of bio-based CaO, with comparable chemical characteristics, that greatly enhance the transesterification activity. However, CaO catalyzed transesterification is limited in its stability and studies have shown deterioration of catalytic reactivity when the catalyst is reused for several cycles. For this reason, different approaches are reviewed in the present study, which focuses on modification of waste-shell derived CaO based catalyst with the aim of better transesterification reactivity and high reusability of the catalyst for biodiesel production. The catalyst stability and leaching profile of the modified waste shell derived CaO is discussed. In addition, a critical discussion of the structure, composition of the waste shell, mechanism of CaO catalyzed reaction, recent progress in biodiesel reactor systems and challenges in the industrial sector are also included in this review.
