An immobilized hydrogen-producing consortium investigated biohydrogen production from food waste using a combination of sodium alginate and cassava rhizome biochar. We investigated the effect of varying the biochar concentration from 0 to 3% and the size of immobilized cells from 1 to 7 mm. Immobilized cells were prepared using 50% (v/v) enriched hydrogen-producing consortium, 2% (w/v) sodium alginate, and 0 to 3% (w/v) cassava rhizome biochar. The optimal conditions for achieving the highest hydrogen production in the batch fermentation reactor were identified as a biochar concentration of 2% (w/v) and an immobilized cell size of 2 mm. The highest hydrogen yield, maximum hydrogen production rate, and lag time recorded were 0.69 mmol H2/g-COD, 0.02 mmol H2/g-COD.h, and 41.51 h, respectively. This research highlights the potential of cassava biochar technology for efficient biohydrogen production from food waste, contributing to renewable energy generation and sustainable waste management. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2024.

Manganese-based lithium ion-sieve are a widely researched lithium adsorbent for the extraction of lithium from liquid resources. However, practical applications face challenges such as severe pressure drop, significant adsorbent loss, poor flowability, and difficulty in recovery, which urgently require the development of effective molding techniques. Based on previous work, this paper employs a non-solvent induced phase separation method to prepare spherical lithium ion-sieve precursor particles PLMO with N,N-dimethylformamide as a solvent, deionized water as a solvent extractant, and polyvinyl chloride as a binder. The surface morphology and hydrophilicity of the particles are controlled by the surfactant sodium dodecyl sulfate (SDS). After acid treatment, spherical lithium ion-sieve particles PHMO are obtained. The results show that PVC is physically uniformly mixed with the powder, and the particles have a stable structure with a porous outer layer and finger-like support layers. Compared to without surfactant, the addition of 5% SDS increases the PLMO particle porosity from 0.190 cm3/g to 0.196 cm3/g, and the PHMO adsorption capacity from 12.73 mg/g to 14.66 mg/g. The adsorption process follows the Langmuir and pseudo-second-order kinetic models, and it exhibits high selectivity for Li+ in a lithium-containing waste solution. Therefore, the surfactant assisted molding technology proposed in this paper holds promise for industrial application. © 2024, The Authors. All rights reserved.

The effect of Mg2+ ions on the purity of calcium sulfate hemihydrate (HH) in concentrated phosphoric acid solution (wt% P2O5 39) was studied, using a continuously mixed suspension mixed product removal (MSMPR) crystallizer. Impurity distribution into crystals in the MSMPR crystallizer was considered by the population balance equation. The presence of Mg2+ ions make the crystals needle-like and agglomerated in large quantities, leading to more three-dimensional defects formation. This effect on crystals increases the uptake ratio (U) of phosphate and reduces HH purity and phosphorus yield. Through the scanning electron microscopy (SEM) and the focused beam reflectance measurement (FBRM), the effect of Mg2+ ions in inhibiting the radial growth of crystals and increasing the critical nuclear radius (rcrit) of crystals in solution was discovered. The influence of Mg2+ ions is crucial for the preparation of HH in the phosphoric acid hemihydrate process. © 2023, The Authors. All rights reserved.

The aim of the present study was to investigate on the inventory and determination of the nutritional value of cereals flour and cassava leaves powder in order to analyse their use in the production of infant flour. In this paper, a A survey to identify the cereals used in the preparation of infant porridge in the Northern Cameroon was done by using 447 mothers having children between 06 and 59 months from areas (Gbakoungue, Sassa-Mbersi, Sanguere-Ngal and Kotkong-Wouldata) with high rate on malnourished children. Flour was prepared from the most preponderant cereals and Cassava leaves powder from varieties identified by the Regional Centre of Agricultural research (CRRA) of Wakwa and local population. Flour and powder samples obtained were subjected to chemical composition analysis. Parameters analysed were crude proteins, total carbohydrates, ash, total fats, total phenols, total tannins, total carotenoids, vitamin C or cyanide. Also Iron, calcium and zinc were determined. The results revealed that white maize (62%) was the main cereal used in the preparation of infant porridge followed respectively by red sorghum, white rice and muskwari. Ten cassava varieties were identified: three (03) by CRRA (TME, 96/1/14 and IRAD 4115) and seven (south, gambada, sweet, Benin, six months, M. glaziovii and grouna) by local population. Amongst cereals flour, those from white maize indicated high protein (10.09%), carbohydrates (84.46%) and total fat (7.46%) contents. The powder from 96/14/14 cassava variety showed high amount of iron (11.98 mg/100g), calcium (751.02 g/100g) and low cyanide content (1.21 ppm) amongst all the cassava leaves powder samples. The supplementation of white maize flour by cassava leaves powder from 96/14/14 variety could therefore be recommended for the preparation of infant flours.

Diosgenin is an influential intermediate for the preparation of various steroidal drugs, and has the reputation of "mother of hormones" and "medicinal gold". In this work, UiO-66-NH2 is quaternary ammoniated by functional modification of 3,5-diamino-1,2,4-triazole and then ion-exchanged with different concentrations of CF3SO3H to produce ionic liquids grafted MOF-based solid acids, namely UNS-0.96 and UNS-1.28, where 0.96 and 1.28 represent the volume (mL) of CF3SO3H consumed. They were used to extract diosgenin from total saponins, suggesting that UNS-1.28 can achieve high diosgenin extraction with a shorter time (2.5 h) and a lower addition amount (0.15 g) and the optimum diosgenin yield of 22.5 % was obtained. The extraction efficiency is higher than that obtained by hydrolysis of 2 M H2SO4 and commercial ion exchange resins. Kinetic studies have shown that the catalytic of total saponins by UNS-1.28 is in perfect agreement with the pseudo-first-order kinetic model, and that the activation energy required for extraction is low, only 2.83 × 104 J/mol. In addition, HPLC-MS was used to analyze the total saponins and products at different extraction times. The fragmentation peak types and relative abundances of the different extracted products are compared to reveal the cleavage pathways of the total saponins and the optimal period of diosgenin production, and to suggest the mechanism of action of the solid acid on the total saponins. © 2025 Elsevier B.V.

Environmental pollution poses a major hurdle to sustainable development, and harnessing solar energy for water treatment has emerged as a promising solution. In this study, flexible, macroporous photocatalytic membranes were developed by combining photocatalysis with membrane separation technology and hydrogen peroxide (H2O2), aiming to improve the degradation efficiency of tetracycline (TC). The g-C3N4/BaTiO3/PVDF photocatalytic membranes were fabricated using a phase inversion method, which successfully addressed challenges such as catalyst agglomeration and recovery difficulties, surpassing traditional membrane separation methods. Additionally, the g-C3N4/BaTiO3 photocatalyst exhibited excellent compatibility with PVDF. Under 120 min of xenon lamp irradiation, the membranes achieved a TC degradation efficiency of 90.63 %. These membranes also demonstrated remarkable permeability, and they maintained high stability and reusability after five degradation cycles, showcasing their promising potential for photocatalytic water treatment applications. © 2025 The Korean Society of Industrial and engineering Chemistry

In recent years, the production of nanomaterials (NMs) has attracted significant attention due to their unique properties and potential applications across diverse industries. However, ensuring the production of safe NMs, particularly at scale, remains a significant challenge. This paper presents Safety by process Control, a novel framework to implement Safety by Design (SbD) in the production stage that integrates dynamic first-principles modeling, Model Predictive Control (MPC) and real-time monitoring of safety-related characteristics. The integration of a toxicity prediction model allows for the proactive management of potential health risks. This approach enables the real-time prediction and adjustment of critical NM properties, such as size distribution and toxicity, directly within the production process. Through a case study on silver nanoparticles (Ag NPs), it is demonstrated that the proposed framework offers a scalable and efficient approach for producing high-quality and safe NMs, which can be easily adapted to various other types of NMs. © 2024, The Authors.
