Al2O3-Cu hybrid nanofluid flow and heat transfer characteristics in the duct with various triangular rib configurations
Published 2024“…Key findings include: (1) the 60° rib configuration produced the highest local heat transfer coefficient, with the maximum occurring at the rib centers. (2) Increasing nanofluid concentration and Reynolds number enhanced heat transfer but reduced skin friction. (3) The optimal performance was achieved with 2 vol.% Al2O3–Cu at Re = 60,000. (4) Velocity contours revealed larger recirculation zones for 60° ribs compared to 45° and 90° configurations. (5) Turbulent kinetic energy was highest for 60° ribs, contributing to enhanced thermal performance. …”

Quorum sensing signal autoinducer-2 promotes hydrogen peroxide degradation in water by Gram-positive bacteria
Published 2024“…We further sought to understand the key mechanism underlying the promotion effect of AI-2 on hydrogen peroxide degradation is that, AI-2 contributed to the resistance of strain Y35 to oxidative stress induced by hydrogen peroxide, and altered membrane permeability of strain Y35 that allowed more hydrogen peroxide to enter bacterial cells and be degraded. …”

Part I : Peptide functionalized materials for gram-negative bacteria targeted PDT and LPS sensing....
Published 2014“…Generally, Gram-negative bacterial pathogens have additional outer membranes mainly composed of highly conserved and unique lipopolysaccharide (LPS) molecules, which serve as permeability barriers to prevent the cell bodies from toxic antimicrobial molecules1-2 including many photosensitizers, which have been successfully used in photoinactivation of Gram-positive strains.3-4 Furthermore, LPS, a potent inducer to human innate immune systems, hence called endotoxin, is now primarily responsible for sepsis associated with the infections of Gram-negative pethogens.5-6 Therefore, the most promising strategy is use of LPS neutralizing peptide as the binding ligand to deliver antibacterial agents meanwhile minimize the side effects.7 The first objective of the research in part I is the design and synthesis of photosensitizer-peptide conjugates for multivalent targeted cellular imaging and photodynamic inactivation (PDI) against Gram-negative bacterial strains. …”
