The Metabolic Core and Catalytic Switches Are Fundamental Elements in the Self-Regulation of the Systemic Metabolic Structure of Cells
(Public Library of Science, 2011-11-18)
Background: Experimental observations and numerical studies with dissipative metabolic networks have shown that cellular enzymatic activity self-organizes spontaneously leading to the emergence of a metabolic core formed ...
Magnetization reversal and exchange bias effects in hard/soft ferromagnetic bilayers with orthogonal anisotropies
(IOP Publishing LTD, 2012-11-02)
The magnetization reversal processes are discussed for exchange-coupled ferromagnetic hard/soft bilayers made from Co0.66Cr0.22Pt0.12 (10 and 20 nm)/Ni (from 0 to 40 nm) films with out-of-plane and in-plane magnetic easy ...
White Light Emission by Simultaneous One Pot Encapsulation of Dyes into One-Dimensional Channelled Aluminophosphate
(MDPI, 2020-06-16)
By simultaneous occlusion of rationally chosen dyes, emitting in the blue, green and red region of the electromagnetic spectrum, into the one-dimensional channels of a magnesium-aluminophosphate with AEL-zeolitic type ...
Electro and magnetoactive printed bi-functional actuators based on alginate hybrid hydrogels
(Elsevier, 2022-10)
Soft materials are attracting much attention for the development of biostructures able to mimic the movement of natural systems by remote actuation. Multi-sensitive hydrogels are among the best materials for obtaining ...
Dynamic and Self-Healable Chitosan/Hyaluronic Acid-Based In Situ-Forming Hydrogels
(MDPI, 2022-07-29)
In situ-forming, biodegradable, and self-healing hydrogels, which maintain their integrity after damage, owing to dynamic interactions, are essential biomaterials for bioapplications, such as tissue engineering and drug ...
Photocrosslinkable and self-healable hydrogels of chitosan and hyaluronic acid.
(Elsevier, 2022-09)
Biocompatible and biodegradable hydrogels with biomimetic properties, such as self-repairing, are increasingly interesting for biomedical applications, particularly when they can be printed or in situ formed to mimic ...
The Number of Catalytic Elements Is Crucial for the Emergence of Metabolic Cores
(Public Library of Science, 2009-10-19)
Background: Different studies show evidence that several unicellular organisms display a cellular metabolic structure characterized by a set of enzymes which are always in an active state (metabolic core), while the rest ...
Acetoxymethyl-BODIPY dyes: a universal platform for the fluorescent labeling of nucleophiles
(Royal Society of Chemistry, 2022)
Current methods for the preparation of functional small-molecule fluorophores generally require labor-intensive, multi-step synthetic routes for all the major chromophoric groups. In spite of recent significant contributions ...
Size Effect in Hybrid TiO2:Au Nanostars for Photocatalytic Water Remediation Applications
(MDPI, 2022-11-08)
TiO2:Au-based photocatalysis represents a promising alternative to remove contaminants of emerging concern (CECs) from wastewater under sunlight irradiation. However, spherical Au nanoparticles, generally used to sensitize ...
Functionalized Fluorescent Silica Nanoparticles for Bioimaging of Cancer Cells
(MDPI, 2020-09-29)
Functionalized fluorescent silica nanoparticles were designed and synthesized to selectively target cancer cells for bioimaging analysis. The synthesis method and characterization of functionalized fluorescent silica ...
