Summary: In this study, silica fume (SF) was coated with graphene oxide (GO) to enhance its utilization efficiency in cementitious composites. The addition of modified SF and GO resulted in significantly improved compressive strength and reduced water sorptivity of the cement paste. This was mainly due to increased polymerization of calcium silicate hydrates and refinement of pore structure.

Summary: Alzheimer's disease, characterized by the accumulation of neurotoxic amyloid-beta protein in the brain, can be effectively treated using disease-modifying anti-amyloid-beta immunotherapy. This therapy utilizes monoclonal antibodies to promote clearance and inhibit the aggregation and synthesis of amyloid-beta. Passive immunotherapy shows promise in treating this neurodegenerative disease, and further clinical trials are being conducted to improve its efficacy.

Summary: A simple co-precipitation technique was used to synthesize MoO3 nanostructures with different surfactants. The physicochemical characterization revealed that the MoO3 nanostructures, with or without the surfactants, exhibited an orthorhombic crystalline phase. The SDS-assisted MoO3 nanoparticles showed enhanced photocatalytic activity, degrading 95.4% of Rhodamine B molecules under UV light irradiation within 140 minutes. The trapping experiment revealed that the addition of two radicals significantly influenced the photocatalytic degradation percentage, reducing it to less than 50%.

Summary: This article explores the possible neural basis of the repeated attraction to watching movies and pays tribute to Prof. Eran Zaidel, who made remarkable contributions to neuroscience and had a passion for movies. Movies, as an art form, involve the collaboration of diverse artists with specialized skills and creativity. The attention and attraction to artworks have deep biological roots. Despite extensive studies on the nature of art, the neural underpinnings of the repeated attraction to movies have been understudied. This perspective proposes clues from non-film research, suggesting the involvement of the mesolimbic reward pathway, brain regions sensitive to facial beauty, pictorial art aesthetics, and music-induced dopamine release in the repeated attraction.

Summary: This study presents the magnetic properties of MnxZn1-xFe2O4 (x = 0.5, 0.6, 0.7) nanoferrite particles prepared by sol-gel auto combustion method. The deviation of the oxygen positional parameter (U) from the ideal value of 0.375 indicates cation redistribution in the ferrite systems. The variation of bond angles suggests strengthening of A-B superexchange interaction. The ferrite nanoparticles exhibit single domain state and superparamagnetism, with increasing saturation magnetization (Ms) and decreasing coercivity (Hc) with higher Mn2+ ion concentration.
