Synthesis of (2-fluorophenyl) and (4-fluorophenyl)-(2-nitromethyl)-methanones as precursors of fluorinated prostanoids [PDF]

open access: yes, 2014
The synthesis of new fluorinated primary nitrocompounds ?(2-fluorophenyl)and (4-fluorophenyl)-(2-nitromethylcyclopentyl)methanones has been realized by the nitromethane 1,4-addition to 1-acylcyclopentenes, available by the reductive cleavage of ...

Visibly transparent & radiopaque inorganic organic composites from flame-made mixed-oxide fillers [PDF]

open access: yes, 2018
Radiopaque composites have been produced from flame-made ytterbium/silica mixed oxide within a crosslinked methacrylate resin matrix. The refractive index of the filler powder increased with ytterbium oxide loading. A high transparency was achieved for a

Enhanced Catalytic Cycle of Glucose Oxidation and Reactive Species with ROS and RHS Generation Mediated by Galvanic Engineering of Dual Atomic Sites on Covalent Organic Frameworks Demonstrating Synergistic Bimetal Tumor Treatment

open access: yesAdvanced Science, EarlyView.
A galvanic replacement is used to control dual atomic metals (Au and Ir) on a covalent organic framework (COF) nanoparticle and then coated with hyaluronic acid (HA). Under a specific bimetallic ratio (COF/Aux/Ir1‐x), the optimization can be achieved for the conversion of intracellular nutrients into reactive species (HOCl and O2• ─) and effectively ...

Hydrogen‐Producing Catalysts Based on Ferredoxin Scaffolds

open access: yesAdvanced Science, EarlyView.
Selected plant‐type ferredoxins that lack their natural [2Fe‐2S] clusters functionally bind a hydrogenase active site cofactor and act as hydrogenases themselves. In combination with photosystem I, the light‐dependent H₂ evolution almost matches the H₂ production rates of the natural system.

Bio‐Inspired Strategy for Radiation‐Based Thermal Management and Utilization

open access: yesAdvanced Science, EarlyView.
Biological organisms have evolved remarkable strategies to manage and exploit thermal radiation. This review explores bio‐inspired systems that mimic these adaptations—such as radiative cooling, thermal regulation, thermal insulation, water harvesting, infrared camouflage, and infrared detection—and highlights their application in thermal management ...

Wide‐Temperature Electrolyte Design via Cation‐Anion Solvation Engineering for 4.6 V Lithium‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
This work proposed a synergistic cation‐anion solvation engineering strategy for wide‐temperature and high‐voltage electrolytes. The superior ionic conductivity under subzero temperatures, excellent thermal stability, and induced inorganic‐rich cathode‐electrolyte interphase endow the LiCoO2 cathodes reliable performance under harsh conditions with a ...

DNase I‐Mediated Chemotactic Nanoparticles for NETs Targeting and Microenvironment Remodeling Treatment of Acute Ischemic Stroke

open access: yesAdvanced Science, EarlyView.
The neutrophil extracellular traps (NETs) play an important role in reperfusion injury in ischemic stroke. Here, considering the unique vascular localization of NETs, a DNase I‐mediated NETs‐targeting nanoparticle is developed to integrate the catalytic and chemotactic functions of DNase I and achieve the synergistic regulation of the internal and ...
