Redefining Separator Design and Water Activity for High‐Energy Zinc Batteries Using Covalent Organic Framework

open access: yesAdvanced Materials, EarlyView.
Device‐level zinc batteries are energy‐limited by the mass/volume of inactive components, while lean‐electrolyte operation triggers interfacial water depletion and unstable kinetics. Here we elucidate lean‐failure mechanisms and develop a COF@PAN functional separator that regulates hydrogen‐bonding networks to manage water activity and accelerate ...

Hydrogel‐Based Airway‐on‐Tube With Perfusable Endothelial Lumen and Outward Epithelialization

open access: yesAdvanced Materials, EarlyView.
A hydrogel‐based airway‐on‐tube platform featuring a perfusable endothelial lumen and outward epithelialization is presented. The system supports primary human bronchial epithelial and lung microvascular endothelial coculture under air‐liquid interface conditions.

Study of a Novel Bi‐Layered Thermoplastic Polyurethane Patch for Congenital Diaphragmatic Hernia

open access: yesAdvanced Materials Interfaces, EarlyView.
Large congenital diaphragmatic hernia remains a challenge due to the poor compatibility of current prostheses. To tackle this problem, a bilayer thermoplastic polyurethane patch with tunable mechanical properties is engineered, whose fibrous side supports rapid fibroblast and myoblast colonization, while the smooth film limits adhesions.

Light‐Controlled Exposure of Cancer Cells to Reactive Oxygen Species Using Organic Semiconductor Thin Films

open access: yesAdvanced Materials Interfaces, EarlyView.
Spin‐coated films of the conjugated polymer F8T2 (poly (9,9‐dioctylfluorene‐alt‐bithiophene)) generate superoxide at the film‐medium interface, enabling precise delivery of reactive oxygen species (ROS) as visible‐light “ROS patches.” Coated surfaces drive rapid, localised cytotoxicity in MCF7 cancer monolayers under white light, providing a reagent ...

Suppressing Metal–Molecule Charge Transfer With a Phosphorus Interlayer

open access: yesAdvanced Materials Interfaces, EarlyView.
Phosphorus forms stable reconstructions with remarkable properties on various metal substrates. Here, using a spectroscopic approach, its role as an effective buffer layer on Cu(110) is demonstrated, preventing charge transfer to adsorbed Zn‐tetraphenylporphyrins (ZnTPP).

Radiotherapy Enhancement by Gold Nanocluster‐functionalized Nanoliposomes Using Polychromatic Orthovoltage X‐ray Irradiation

open access: yesAdvanced Materials Interfaces, EarlyView.
Lipid drug carriers to which ultra‐small gold nanoparticles were added enabled more efficient radiotherapy of cultured pancreatic cancer tumors. These nanoparticles boosted radiation‐induced damage to tumors by generating more reactive molecules, though higher gold levels are needed for strong benefits.

Black Holes [PDF]

open access: yesessentials, 2021
Who says you can't get anything out of a black hole? In the past two years, astronomers have taken unprecedented aim at the first black hole ever found, Cygnus X-1. Using a vast armada of instruments, they have pinpointed Cygnus X-1's distance, which has

Black Holes and Entropy

Jacob Bekenstein, 1973
There are a number of similarities between black-hole physics and thermodynamics. Most striking is the similarity in the behaviors of black-hole area and of entropy: Both quantities tend to increase irreversibly. In this paper we make this similarity the
