Optical Hydrogen Sensing Materials for Applications at Sub‐Zero Temperatures

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates the viability of optical hydrogen sensors at temperatures as low as −60°C. Using advanced metal hydride materials, the sensors detect hydrogen with high sensitivity, speed, and stability across a wide range of concentrations. These findings open doors for safe hydrogen detection in extreme cold, enabling applications in aviation,

Hierarchically Engineered Triple‐Defensive Antifouling Coating with Well‐Regulated Structure for Enhanced Wastewater Treatment

open access: yesAdvanced Functional Materials, EarlyView.
Inspired by shark skin, which has a hydrophilic “denticle layer” and a low surface energy “mucus layer,” a triple‐defense antifouling coating is developed. This coating features a robust hydrophilic catalytic nanoparticle layer overlaid with dispersed hydrophobic perfluoro‐silane domains, optimizing fouling resistance, release, and degradation for ...

Switching From Acceptor to FRET Donor: How the Organic Solar Cell Architecture Can Change the Role of a Chromophore

open access: yesAdvanced Functional Materials, EarlyView.
The non‐fullerene acceptor o‐IDT‐BT‐DCV is used in both binary and ternary blends to investigate the role that it plays in each device architecture. The charge generation pathways are found to differ between the binary and ternary blends with o‐IDT‐BT‐DCV becoming a second donor in the ternary blend.

Sonochemical Functionalization of Glass

open access: yesAdvanced Functional Materials, EarlyView.
A new method for functionalizing glass using ultrasonication of aryl diazonium salts. Aryl radicals generated by ultrasounds react with glass, forming a stable, covalently bonded organic film. The functionalized glass adheres microorganisms such as microalgae, fungi, and bacteria, suggesting potential applications in enzyme production, filtration ...

Air Transport

Pediatric Clinics of North America, 1993
Air transport has become an integral element of pediatric transport programs. The use of both fixed-wing (airplane) and rotorwing (helicopter) aircraft has increased. Appropriate vehicles configured for the safe and effective transfer of pediatric and neonatal patients are available. As the acuity of patients requiring air transport has increased, more

Tourism and air transport

The Tourist Review, 1973
While scheduled airlines calculate their load factor at 50% of the plane's seats, the tour operators usually calculate a seating density of 85–90%. The reason for this is that the tour operator is almost sure of selling the seats long before the departure time because he does not launch the package before he is certain, through a market study, that ...
