Crystals formed in confinement exhibit higher degrees of crystallinity and lower quantities of secondary-phase defects: the formation of well-ordered layers and shells appears to be promoted by flat walls and spherical container interfaces.

These benefits enhance plant growth while minimizing negative environmental impacts. The addition of reused materials (recycle) significantly influences the size distribution and strength of granular fertilizers. It was determined that incorporating 60% recycle increases the part of commercial granules (size 2.0–4.0 mm) from 22% to about 68%. However, this increase is accompanied by a decrease in static strength, which drops from 2.8–3.8 MPa to 1.7–2.3 MPa. Modelling granulation processes holds substantial potential for the fertilizer industry, enabling the optimization of high-quality granular fertilizer production while minimizing the need for extensive experimental trials. This approach not only streamlines manufacturing but also ensures consistent nutrient supply, ultimately contributing to improved crop yields and sustainable agricultural practices. In this study, a simulation model based on an actual granulation drum was used to investigate the granulation process of a mixture containing recycled material, crystalline urea, and the microalgae <em>Chlorella vulgaris</em> sp.

In a combinatorial sense, there exists an immense number of specific IL–solvent combinations. An exhaustive experimental or even simulation-based investigation of the chemical space spanned by such combinations can be extremely time-consuming, expensive, and nearly impossible. An alternative approach is to employ machine learning-based models developed from available databases. Although there exists prior literature that integrates machine learning to investigate mixtures of specific solvents with ILs, these models lack generalization necessitating development of a large number of ML models to handle various solvents. To remedy this shortcoming, as a part of designing green electrolytes with high ionic conductivity that can have potential applications in next-generation batteries and solar cells, this work aims to develop a unified machine learning model to predict ionic conductivity of any IL–solvent mixture system. In this regard, three models, namely, Random Forest, extreme gradient boosting (XGBoost), and artificial neural network (ANN) were formulated using the NIST ILThermo database. The dataset contained 549 unique ionic liquids from 16 cation families and 81 unique solvents, representing a total of 23 712 datapoints. SHAPLEY additive explanation (SHAP) method was used to assess the impact of various features on model prediction and their significance was compared with literature to gain physical insight about the model behavior. Finally, using the developed models, approximately 2.5 million IL–solvent mixtures at five different compositions were screened at room temperature. The high-throughput screening yielded nearly 19 000 IL–solvent mixtures for which ionic conductivity was found to exceed the ionic conductivity of conventional Li-ion battery electrolyte.</p>","PeriodicalId":91,"journal":{"name":"Molecular Systems Design & Engineering","volume":" 2","pages":" 167-180"},"PeriodicalIF":3.2,"publicationDate":"2025-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2026/me/d5me00146c?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146147812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These membranes are designed through two principal strategies, <em>i.e.</em> pore-filling and surface/interface engineering. Hydrogels could also be used, especially in biomedical applications, with fibre reinforcement to enhance mechanical stability. Pore-filled or “gel-in-shell” membranes incorporate hydrogels or functional soft materials within porous polymer matrices, combining chemical functionality with structural support. These systems enable the fast and selective transport of ions or molecules, finding applications in fuel cells, batteries, solar desalination, and water purification. Stimuli-responsive designs, where thermally, chemically, piezoelectric or optically sensitive polymers are grafted within or onto membrane pores, enable dynamic control over permeability, critical for smart drug delivery and adaptive filtration. Self-healing hydrogels, driven by dynamic bonding or ionic crosslinking, further enhance membrane longevity under operational stress. On the surface engineering side, functionalization <em>via</em> plasma treatment, graft polymerization, layer-by-layer assembly, molecular layer deposition, or mussel-inspired polydopamine coatings enables control over surface charge, hydrophilicity, and antifouling performance. Advanced materials such as MOFs and MXenes could also be incorporated in membrane designs to enhance functional properties. These engineered interfaces, such as surface patterning or nanofiber anchoring of the surface, are crucial for addressing challenges such as fouling, poor selectivity, and biocompatibility issues typically encountered in traditional membranes. Fibre-reinforced hydrogels further expand the application scope into biomedical systems, offering tissue-like mechanical resilience for tissue scaffolds, wound dressings, and wearable biosensors.
