Advanced Science, EarlyView.In this work, a series of single‐site metal phthalocyanine catalysts (MPcs (M = Zn, Co, Ni, Cu, and Fe)) are screened to learn their activity‐selectivity relationship in the co‐reduction reaction of CO2 and nitrates toward urea formation, which can be significantly promoted by enhanced adsorption of *HOOCNO, reduced adsorptions of *N and *COOH, and ...

Advanced Science, EarlyView.Inspired by the structural and functional characteristics of bone, bionic nanomaterials combined with nanotechnology can more accurately replicate stem cell niches, enabling the design of bone tissue engineering scaffolds with diverse nanoscale properties to promote stem cell migration, proliferation, and differentiation. This precise control over stem

Advanced Science, EarlyView.Obese gut‐microbiota derived lipopolysaccharides (LPS) induce bone marrow macrophage senescence and GCA secretion via activating TLR4/NF‐κB/MAPKs pathway. Clinically, obese patients are associated with higher serum GCA levels. Mice with depletion of GCA gene show resistance to skeletal deterioration caused by obesity and LPS‐induced chronic ...

Television noise reduction device [PDF]
, 1975 A noise reduction system that divides the color video signal into its luminance and chrominance components is reported. The luminance component of a given frame is summed with the luminance component of at least one preceding frame which was stored on a ...

Advanced Science, EarlyView.Based on the poor cartilage penetration of tFNA, a novel tFNA‐2WL with excellent cartilage permeability and perfect chondrocyte endocytosis properties is designed and fabricated. As a result, tFNA‐2WL has a nearly seven‐fold increase in the penetration depth into the cartilage, with the same excellent cell entry properties as tFNA.
