As a corollary, the present research highlights the synthesis of pristine sewage sludge biochar (SSB) and NaOH-functionalized sewage sludge-based biochar (NaOH-SSB) adsorbents for the decolorization of Rhodamine B (RhB) dyeing wastewater. NaOH-SSB exhibited maximum adsorption capacity values of 8.72 mg g^–1, twice that of SSB (4.29 mg g^–1) at RhB concentrations of 15 mg L^–1. The adsorption process was modeled using the Levenberg–Marquardt Back Propagation Algorithm optimized by Genetic Algorithm to train the Artificial Neural Network and predict RhB removal using biochar adsorbents.

However, a huge challenge in applying PINNs to bioprocesses is developing a loss function that synergizes different bioprocess dynamics. To mitigate this challenge, a novel physics-based deep learning method was developed by integrating order-of-magnitude analysis to the loss function of PINNs (oPINNs) using biological first principles. Compared to standard PINNs and numerical methods for solving the forward problem of linear chromatographic models, oPINNs demonstrated notable improvements: an order-of-magnitude enhancement in accuracy with an equivalent sample size, or a 32-fold reduction in sample size for equivalent accuracy, along with a 1000-fold acceleration in computational speed for millisecond-scale simulation. Moreover, oPINNs showed exceptional robustness in weight determination and hyperparameter selection amidst variations in chromatographic model parameters. In summary, oPINNs represent a significant advancement in integrating physics-based deep learning into hybrid modeling of bioprocesses, particularly for developing real-time digital twins.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"78 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143055683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effect of ultrasound irradiation time, power, and physicochemical properties of oil on the dispersed phase volume and dispersed phase droplet size has been studied. The increase in the irradiation time increases the dispersed phase volume, while it decreases the dispersed phase droplets size. With an increase in the ultrasonic irradiation power, there is an increase in the fraction of volume of the dispersed phase, while the droplet size of the dispersed phase decreases over the same irradiation time. The fractional volume of the dispersed phase is higher for the case of the groundnut oil–water system, while it is low for the paraffin (heavy) oil–water system. The droplet size of soyabean oil dispersed in water is found to be small, while that of paraffin (heavy) oil is found to be large. These variations could be explained on the basis of varying physicochemical properties of the system, i.e., viscosity of oil and the interfacial tension. During the ultrasonic emulsification, a coalescence phenomenon which is relatively weak has also been observed, which can be attributed to the collision of small droplets when the droplet concentration increases (higher dispersed phase hold-up) and the acoustic streaming strength is higher.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"49 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143056938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, template-assisted electrospinning was used to fabricate microhemispherical thermoplastic polyurethane (TT) nanofiber membranes. The preparation of MXene@CNTs/TT (MCTT) nanofiber membranes was conducted via the ultrasound-assisted dip-coating method, utilizing MXene and carbon nanotubes (CNTs) as composite conductive materials. Subsequently, polydimethylsiloxane (PDMS) encapsulation was employed to prepare PDMS-MCTT conductive nanofiber membranes. Utilizing an aligned assembly strategy based on the microhemispherical structure, the PDMS-MCTT bilayer pressure sensor exhibits high sensitivity (<i>S</i>_max = 471.3 kPa^–1), wide pressure range (0–521.6 kPa), low detection limit (0.003 kPa), fast response time (7 and 8 ms) and reliable cycling performance (3000 cycles).

Nano–Cu–Ce oxide-modified activated carbon adsorbents with different active components are synthesized by the sol–gel method and ball milling method. The adsorption properties of the materials are tested by the fixed-bed adsorbent evaluation system. The results show that 15%CuCe_0.75O_<i>x</i>/activated carbon (CAC-15) has the best adsorption performance for H₂S, reaching 103.58 mg/g in an O₂-free ambience under 40 °C. The composite had high adsorption capacity for H₂S, and its adsorption property decreases with the increase of space velocity and H₂S concentration and fluctuates with the increase of temperature. At 60 °C, the maximum absorption capacity is 155.59 mg/g. The desulphurization process includes active adsorption and catalytic oxidation, and the adsorption capacity is determined by the chemical property and surface structure of the active component. The adsorbent has a highly mesoporous structure, which was highly dependent on the loading of the Cu–Ce–O active component. The results of chemical characterization show that sulfur was the main adsorption product, and strong alkaline sites play a major role. The mechanism of H₂S adsorption by the adsorbent is described. This study provides new insights into the Cu/Ce-doped activated carbon adsorbent and the reactive adsorption of H₂S.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"77 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143055681","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, combined carbothermal reduction–acetic acid leaching was proposed, aiming to stepwisely recover Li, Ni, Co, and Mn from spent ternary LIBs containing lithium nickel cobalt manganese oxide (LiNi_<i>x</i>Co_<i>y</i>Mn_<i>z</i>O₂, NCM). The biomass waste materials, chitosan, and chitin were chosen as sustainable reducing agents for carbothermal reduction roasting. The synergistic effect of the reducing gases and biochar produced during pyrolysis led to the reduction of transition metals in NCM into Ni, Co, and MnO, separately. Meanwhile, lithium reacted with CO₂ to form Li₂CO₃. Additionally, an acetic acid leaching process was employed to treat the roasting slag, achieving selective leaching of Li and Mn with leaching efficiencies of 98.45% for Li, 1.20% for Ni, 3.10% for Co, and 98.43% for Mn under optimal conditions. Compared to traditional carbothermal reduction roasting methods, this approach used extracts from shrimp/crab shell solid waste as a source of reducing atmosphere and biochar. More importantly, the leaching behaviors of Li, Ni, Co, and Mn were also investigated. Li and Mn were subsequently recovered as lithium carbonate (Li₂CO₃) and manganese carbonate (MnCO₃), respectively. An economic evaluation was also conducted to present a promising strategy for efficiently recycling valuable metals from spent LIBs.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"9 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143055686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the RE³⁺ extraction efficiency and selectivity still need to be improved in the adsorption process. Herein, a phosphate functionalization biogenic manganese oxide (PR-BMO) was fabricated by a biomineralization method for effective and selective adsorption of RE³⁺. PR-BMO was a complex of biogenic manganese oxide and Mn₂P₂O₇, which exhibited a stacked lamellar structure, had rich surface phosphate groups, and carried a large number of negative charges. The adsorption capacity of PR-BMO for model RE³⁺ (La³⁺) was up to 537.92 mg·g^–1, which was significantly higher than that of BMO without phosphate functionalization and chemical manganese oxides. Adsorption kinetic, isotherm, thermodynamic studies, and spectroscopic techniques revealed the adsorption of RE³⁺ by PR-BMO was a complex but feasible endothermic process, coexisting electrostatic attraction, and coordinated complexation. Owing to the high affinity of phosphate groups to RE³⁺, PR-BMO showed outstanding selectivity for RE³⁺ adsorption despite the presence of typical coexisting ions (Na⁺, K⁺, Mg²⁺, Ca²⁺, Cl^–) and possessed great adsorption capacities toward various RE³⁺ including La³⁺, Ce³⁺, Nd³⁺, Pr³⁺, Y³⁺, and Dy³⁺. Notably, PR-BMO could reduce the concentration of RE³⁺ in low-concentration wastewater to nearly 0 mg·L^–1 and concentrate the RE³⁺ from 10 to 1811.5 mg·L^–1 through enrichment treatment.
