Regulating Solvent‐Separated Ion Pairs to Control Polysulfide Redox for Fast and Stable Room‐Temperature Na‐S Batteries

open access: yesAdvanced Science, EarlyView.
A local high‐concentration electrolyte with tailored solvent‐separated ion pairs is pioneered to design for room‐temperature sodium‐sulfur batteries. This electrolyte allows sparingly dissolved polysulfides and localizes them onto reactive interfaces for liquid‐solid conversion.

Reforms in the Holy Infirmary, 1680 [PDF]

open access: yes, 2007
The Holy Infirmary, at least in theory, bore witness to the very raison d'etre of the Order of St John ­ the care of the infirm. If the knights came to be known as the Hospitallers, it is because the care of the sick became their historical mission ...

Study of Free‐Space Optical Quantum Network: Review and Prospectives

open access: yesAdvanced Science, EarlyView.
Free from the constraints of fiber connections, free‐space quantum network enables longer and more flexible quantum network connections. This review summarizes and comparatively analyzes free‐space quantum network experiments based on ground stations, satellites, and mobile platforms.

Polar Lattice‐Distorted Motifs Enable Synergy of Local Polarization/Dipole Fields for Concurrent Glyphosate Wastewater Remediation and CO Evolution

open access: yesAdvanced Science, EarlyView.
Photocatalytic treatment of glyphosate herbicide in agricultural wastewater is achieved through the cooperative effect of the local polarization field and dipole field mediated by lattice‐distorted carbon nitride. Glyphosate is completely degraded via selective C─P bond cleavage with a CO evolution rate of 1166 µmol g−1 h−1.

Parties and Ballot Access in Latin America: a new trend in a new political context [PDF]

open access: yes, 2013
For the last ten years a group of Latin American countries have passed legal reforms raising ballot access requirements. Although each of these reforms have been profusely discussed in every one of the countries involved, so far, they have not been ...

The Enhanced Whey Protein Oral Bioavailability and Muscle Anabolism Ability by a Simple and Effective Piperine‐Whey Protein Synergistic Codelivery System

open access: yesAdvanced Science, EarlyView.
WP(Pip) is a mixture of whey protein and piperine‐loaded nanoemulsion stabilized by WP through microfluidic homogenization. Acting as a “smart key,” piperine opens epithelial tight junctions to enhance absorption of whey protein and, thereby increasing circulating amino acid availability, synergistically up‐regulates the mTOR signaling pathway in ...

Breaking the Toughness‐Stretchability Trade‐Off in Hydrogels with Dynamic Hydrogen Bonding

open access: yesAdvanced Science, EarlyView.
A novel nanocomposite hydrogel architecture overcomes the inherent conflict between toughness and stretchability by integrating uniformly dispersed aminopropyl‐hybrid‐phyllosilicate nanosheets within a polyacrylamide matrix. This design leverages a dynamic hydrogen‐bonding network to facilitate efficient energy dissipation and self‐recovery.
