Summary: The addition of thiourea (TU) enhances the broad-spectrum antimicrobial activity of D-maltose-capped gold nanoclusters (AuNC-Mal). AuNC-Mal/TU exhibits effective inhibition against multidrug-resistant Pseudomonas aeruginosa with low cytotoxicity. The antimicrobial activity is attributed to the generation of [Au(TU)(2)](+) and smaller AuNCs, increased accumulation of Au in bacteria, and inhibition of thioredoxin reductase.

Summary: Bacterial biofilms are a major problem in chronic wounds and medical devices, and there is a need for reliable imaging and detection methods. Fluorescent glutathione-stabilized gold nanoclusters (GSH-AuNCs) were found to specifically interact with extracellular matrix components of bacterial biofilms, resulting in fluorescent staining. Molecular docking studies showed that GSH-AuNCs have affinity for various targets in the extracellular matrix. The developed method using GSH-AuNCs showed improved sensitivity for biofilm detection compared to standard methods.

Summary: Endolysins, bacteriophage-encoded enzymes, can be used as potential antibacterial agents. Genetic engineering techniques allow customization of their properties and activity against specific bacterial targets, enabling personalized therapies for bacterial infections. Some endolysins can cross the outer membrane of Gram-negative bacteria, enhancing their affinity towards the bacterial surface and membrane permeabilization. However, there is still a need for specific guidelines on implementing modifications to improve the bactericidal effectiveness of endolysins.

Summary: This study aimed to enrich anaerobic ammonium oxidizing bacteria (AnAOB) in the anaerobic ammonium oxidation (anammox) process. Red mud-based carriers were positively charged with FeCl3 and microbial promoters for faster AnAOB enrichment. The experimental results showed significantly increased nitrogen removal rates compared to commercially available carriers. Electrostatic attraction played a leading role in loading AnAOB, and an increase in surface roughness and specific area of the carriers, as well as the presence of certain ions, were necessary for AnAOB growth. The leaching of Cr(VI) promoted the nitrogen removal effect of AnAOB.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

Summary: This research developed an effective approach to enhance the charging rates of lithium ion batteries (LIBs) by strategically incorporating carbon nanotube (CNT) conductivity boosters into Li4Ti5O12 (LTO) electrodes. Multi-layer architectures comprising CNT-rich and CNT-free LTO electrode layers were manufactured using a layer-by-layer spray coating method to promote charge transfer kinetics of high mass loading electrodes. The best performing multi-layer was paired with a spray-coated LiFePO4 (LFP) positive electrode, resulting in attractive power performance that outperformed conventional LTO || LFP combinations.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
