“…After the vapor deposition, AP coatings were left to equilibrate overnight (≈16 h) under vacuum at 20 °C. This equilibration time was chosen because it allowed ample time for pHEMA to equilibrate (typically over 60-100 min) [49,50] while avoiding the potential aging effect (typically over months-years). [51] This also allowed to match training conditions, where the ML model was trained using material properties and biofilm data obtained on well-equilibrated but still fresh polymer microarrays, thus precluding potential effects of equilibration and aging on the learned properties-biofilm relationships.…”

Amphiphilic copolymers (AP) represent a class of novel antibiofouling materials whose chemistry and composition can be tuned to optimize their performance. However, the enormous chemistry-composition design space associated with AP makes their performance optimization laborious; it is not experimentally feasible to assess and validate all possible AP compositions even with the use of rapid screening methodologies. To address this constraint, a robust model development paradigm is reported, yielding a versatile machine learning approach that accurately predicts biofilm formation by Pseudomonas aeruginosa on a library of AP. The model excels in extracting underlying patterns in a "pooled" dataset from various experimental sources, thereby expanding the design space accessible to the model to a much larger selection of AP chemistries and compositions. The model is used to screen virtual libraries of AP for identification of best-performing candidates for experimental validation. Initiated chemical vapor deposition is used for the precision synthesis of the model-selected AP chemistries and compositions for validation at solid-liquid interface (often used in conventional antifouling studies) as well as the air-liquid-solid triple interface. Despite the vastly different growth conditions, the model successfully identifies the best-performing AP for biofilm inhibition at the triple interface.

“…Also, cryogels have open-ended pores which contribute to the fast diffusion in contrast to the closed-end pores of conventional porous materials [57,58,105]. The relatively low surface area can be compensated with a high number of active sites distributed on the cryogel walls and also the adaptability of cryogels as the surface can be easily altered by adding functional groups and ligands, which can greatly contribute to the capacity and selectivity [26,47,52,57,60,71,106]. Moreover, hydrogels and cryogels have the ability to expand their structure due to their high swelling capacity [107,108].…”

“…Cadmium (Cd) is one of the most toxic elements for humans, which is widely used in various industrial activities, inculding alloy manufacturing, smelting, electroplating, pigments, plastics and battery manufacturing 2 . Cd 2+ could enter the human body through the food chain and deposit in various tissues of the body, which would lead to serious diseases and endanger human health and life 3 . According to the joint regulations of the World Health Organization (WHO), the U.S. Environmental Protection Agency (EPA) and the European Public Health Alliance (EPHA), the maximum amount of Cd 2+ contamination in drinking water should not exceed 0.003 mg L −1 4 .…”

In this study, red mud modified by manganese dioxide(MRM) was utilized as an adsorbent to effectively remove Cd2+ from aqueous solution. The characteristics were analysed by SEM–EDS, XRD, BET, FTIR and XPS. Different factors that affected the Cd2+ removal on MRM, such as dosage, initial pH, initial Cd2+ concentration, were investigated using batch adsorption experiments. Simultaneously, the adsorption kinetics, adsorption isotherms and adsorption thermodynamics of Cd2+ were also investigated using adsorption experiments data. The characterization results showed that MRM had a rougher, larger specific surface area and pore volume (38.91 m2 g−1, 0.02 cm3 g−1) than RM (10.22 m2 g−1, 0.73 cm3 g−1). The adsorption experiments found that the equilibrium adsorption capacity of MRM for Cd2+ was significantly increased to 46.36 mg g−1, which was almost three times that of RM. According to the fitting results, the pseudo-second-order kinetic model described the adsorption process better than the pseudo-first-order kinetic model. The Langmuir model fitted the adsorption isotherms well, indicating that the adsorption process was unimolecular layer adsorption and the maximum capacity was 103.59 mg g−1. The thermodynamic parameters indicated that the adsorption process was heat-trapping and spontaneous. Finally, combined XPS and FTIR studies, it was speculated that the adsorption mechanisms should be electrostatic attachment, specific adsorption (i.e., Cd–O or hydroxyl binding) and ion exchange. Therefore, manganese dioxide modified red mud can be an effective and economical alternative to the removal of Cd2+ in the wastewater treatment process.
