Effect of iron powder on hydrogen sulfide reduction and phosphate removal in semi-continuous anaerobic digestion treating primary sludge J. Chem. Technol. Biotechnol. (IF 3.4) Pub Date : 2024-02-07 Seung-Jun Oh, Seung-Han Ha, Eui Jeong Noh, Seung Gu Shin, Johng-Hwa Ahn
To our best knowledge, no experimental study has previously investigated the simultaneous effects of adding Fe powder for the decrease of hydrogen sulfide (H2S) in biogas and the removal of phosphate (PO4-P) in continuous anaerobic digestion (AD). This study investigated the effects of iron (Fe) powder (5 g L−1) in AD to remove H2S and PO4-P. A comparative experiment was conducted using two semi-continuous-flow

ZnO nanomaterials with enhanced antimicrobial activity obtained by Eichhornia crassipes aqueous extract-mediated synthesis J. Chem. Technol. Biotechnol. (IF 3.4) Pub Date : 2024-02-07 Rosendo López González, Mirian Hernández Gutiérrez, Ruth Lezama García, Sergio Alberto Gómez Cornelio, Carlos Lobato, Abraham Gómez-Rivera, Patricia Quintana Owen, Mayra Angélica Alvarez Lemus
Zinc oxide nanoparticles (ZnO NPs) were obtained through precipitation synthesis, using aqueous water hyacinth leaf extract (Eichhornia crassipes) under alkaline conditions. The effect of the extract on the physicochemical and antimicrobial properties of the ZnO was evaluated starting from concentrated extract (labeled as E100) and performing two dilutions of this concentrated extract at 50% and 25%

Evaluation and control of energy-efficient processes for separating epichlorohydrin-oriented quaternary system J. Chem. Technol. Biotechnol. (IF 3.4) Pub Date : 2024-02-07 Fuqiang Qi, Junling Yang, Zhentao Zhang, Zhenqun Wu, Qiyue Ren, Huafu Zhang, Yanan Li, Yu Zhang
The direct epoxidation of allyl chloride is a clean and efficient synthesis method for producing epichlorohydrin (ECH), which is a crucial organic intermediate widely used in the fields of renewable energy and aerospace. However, the presence of multiple azeotropes in the synthesized product using this method complicates the separation process and results in high energy consumption. To efficiently

Polynomial approaches in improving accuracy of probability distribution estimation using the method of moments J. Chem. Technol. Biotechnol. (IF 3.4) Pub Date : 2024-02-07 Meltem Turan, Joakim Munkhammar, Abhishek Dutta
Determination of a probability density function (PDF) is an area of active research in engineering sciences as it can improve process systems. A previously developed polynomial method-of-moments-based PDF estimation model has been applied in the research to produce accurate approximations to both standard and more complex PDF. A model with a different polynomial basis than a monomial is still to be

Enzymatic Knoevenagel condensation in dual-functionalized water-mimicking ionic liquids and tertiary amide solvents J. Chem. Technol. Biotechnol. (IF 3.4) Pub Date : 2024-02-07 Hua Zhao, Chante' D Campbell
Knoevenagel condensation is an important tool for building carbon–carbon (CC) bonds, especially when catalyzed by enzymes to enable a potentially high chemo-, regio- and/or stereoselectivity. Although many Knoevenagel condensation reactions are carried out in aqueous solutions, insoluble hydrophobic substrates often lead to poor catalytic efficiencies. The use of water-miscible organic solvents improves

Ethanol production from sugarcane bagasse by modified PDMS membrane in a membrane bioreactor: pervaporation technique J. Chem. Technol. Biotechnol. (IF 3.4) Pub Date : 2024-02-07 Behzad Zabihi, Mehri Esfahanian
Bioethanol is considered a highly promising alternative to fossil fuels due to its derivation from renewable sources. Reducing the disadvantages of conventional fermentation requires removing the product from the fermentation broth after its formation. Therefore, coupling the membrane separation with a biological process in a single unit leads a reduction of substrate and product inhibitions.

Novel cyano functional small molecule photosensitizers with amplified electron injection and photovoltaic attributes: molecular modelling towards efficient dye-sensitized solar cells J. Chem. Technol. Biotechnol. (IF 3.4) Pub Date : 2024-02-07 Sehar Nadeem, Muhammad Usman Khan, Riaz Hussain, Faiza Shafiq, Norah Alhokbany
The exploration of novel photosensitizers with reverberant optoelectronic features for dye-sensitized solar cells (DSSCs) is a frontline area of research. In this respect, attempts have been made to design a series of novel organic dyes (JFK-1–JFK-10) with D-π-A framework by π-spacer modification strategy. The suitability of developed sensitizers for DSSCs applications is confirmed by executing natural
