Summary: Orbital interactions between adsorbed molecules and metal surfaces are crucial in surface processes. This study investigates the vibrational frequency shift of phenyl isocyanide molecules adsorbed on Pt and Pd covered Au surfaces and Pt2Au4 and Pd2Au4 clusters. The density of states (DOS) analysis reveals the importance of the overlap area between d electronic DOS and molecular sigma or pi* orbitals (Rd-sigma/d-pi*) in explaining the frequency shift of the C N moiety. Experimental simulations support this hypothesis.

Summary: Hydrophobic interactions play a crucial role in various biological and synthetic processes. This study demonstrates that the hydrophobicity of surfaces with chemically heterogeneous compositions can vary substantially depending on the spatial patterns and chemical identities of polar and nonpolar groups. The clustering of nonpolar groups is a common signature of highly hydrophobic patterns, and molecular dynamics analysis reveals its correlation with the perturbation of interfacial water structure.

Summary: The study found that most Staphylococcus aureus isolates showed a significant increase in biofilm production on surfaces coated with plasma proteins. There was no significant difference in biofilm formation between methicillin-resistant and -susceptible isolates, or between different clonal lineages, except for certain subtypes.

Summary: A facile and modular method was developed for assembling a plasmonic/photonic structure by covalently attaching a thermoresponsive polymer film between a gold substrate and CdSe/ZnS quantum dot nanoemitters. The fast and reversible photoluminescence switching of quantum dots demonstrated excellent fatigue resistance and up to 3-fold PL enhancement factors. The modularity of the preparation steps allows precise tuning of film thickness at the nanometer scale, enabling significant control of plasmonic/photonic substructures for optoelectronic and sensing applications.

Summary: In this study, a closed-loop controlled photo-polymerization process was proposed for hydrogel fabrication with controlled storage moduli using bang-bang and fuzzy logic controllers. The composition, structure, and mechanical properties of the hydrogels were characterized to understand the key factors influencing the photopolymerization process. The research advances pulsed and continuous photopolymerization processes for hydrogel engineering based on closed-loop control for reproducible fabrication of hydrogels with controlled mechanical properties.

Summary: This paper introduces a new methodology that integrates machine learning with domain knowledge in biosensing to reduce false results and time delay in biosensors. The methodology was validated for accurate quantification of microRNA using the dynamic response of cantilever biosensors, and theory-guided feature engineering improved the performance of classification models. The technique enabled rapid and accurate quantification of analyte concentration and reduced data acquisition time. The paper also demonstrates model explainability and the method's potential for guiding experiment design in high-performance biosensing applications.
