Summary: An active nanocarrier for chlorhexidine (CHX) based on sterically stabilized shellac nanoparticles with dual surface functionalization has been developed to enhance the antimicrobial action of CHX. Surface modification, encapsulation efficiency, and release kinetics were evaluated for the novel nanocarrier, showing improved antimicrobial effects compared to free CHX on various microorganisms. The enhanced antimicrobial action was attributed to increased electrostatic adhesion between the cationic surface of the nanocarrier and the anionic surface of microorganism cell walls, potentially enabling more efficient formulations in dentistry.

Summary: Nanotechnology involves the study and application of materials, structures, devices, and systems at the nanoscale, which is about one hundred nanometers or smaller. Spray pyrolysis (SP) is a cost-effective method for synthesizing a wide range of nanomaterials, including metals, semiconductors, and ceramics, by decomposing a precursor solution or suspension in a high-temperature environment. There are different types of SP processes, such as tubular reactors and electrostatic spray deposition (ESD), each with unique parameters and requirements. SP has potential applications in fields like nanomedicine, sensing, electrochemical devices, catalysis, and energy conversion and storage, but more research is needed to explore its full potential and develop new applications.

Summary: Magnesium aminoclay nanoparticles (MgANs) have both positive and negative effects on photosynthetic microalgae. This study investigated the use of MgANs in producing algal lipids under high CO2 concentrations. Among three oleaginous Chlorella strains, only KR-1 showed significant improvement in lipid content and extraction efficiency in the presence of MgANs. This improvement was due to increased biosynthesis of triacylglycerols and a thinner cell wall.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
