Covalent Organic Frameworks for Photocatalytic CO2 Reduction: Metal Integration Principles, Strategies and Functions

Advanced Functional Materials, EarlyView.
Covalent organic frameworks (COFs) with metals have been recognized as versatile platforms for photocatalytic CO2 reduction (CO2PRR). Herein, an overview of metal integration strategies for COFs is systematically summarized. Regulatory mechanisms and structure–activity relationships between metal integration and COF‐based CO2PRR are emphasized.

Bio‐Inspired Molecular Events in Poly(Ionic Liquids)

Advanced Functional Materials, EarlyView.
Originating from dipolar and polar inter‐ and intra‐chain interactions of the building blocks, the topologies and morphologies of poly(ionic liquids) (PIL) govern their nano‐ and micro‐processibility. Modulating the interactions of cation‐anion pairs with aliphatic dipolar components enables the tunability of properties, facilitated by “bottom‐up ...

Road safety performance indicators for the interurban road network

Accident Analysis and Prevention, 2013
Various road safety performance indicators (SPIs) have been proposed for different road safety research areas, mainly as regards driver behaviour (e.g. seat belt use, alcohol, drugs, etc.) and vehicles (e.g. passive safety); however, no SPIs for the road network and design have been developed. The objective of this research is the development of an SPI

Is road safety management linked to road safety performance?

Accident Analysis and Prevention, 2013
This research aims to explore the relationship between road safety management and road safety performance at country level. For that purpose, an appropriate theoretical framework is selected, namely the 'SUNflower' pyramid, which describes road safety management systems in terms of a five-level hierarchy: (i) structure and culture, (ii) programmes and ...

Modeling road-cycling performance

Journal of Applied Physiology, 1995
This paper presents a complete set of equations for a “first principles” mathematical model of road-cycling performance, including corrections for the effect of winds, tire pressure and wheel radius, altitude, relative humidity, rotational kinetic energy, drafting, and changed drag.

Road Network Performance Measurements

2023
Road Network Performance (RNP) impacts economic, ecological, and social sustainability. Nonetheless, models for road transport cost estimation often fail to account for the regional specificity of RNP. While the availability of suitable tools, data sources, and computational capacities to measure concrete RNP on a wide scale has steadily increased ...

Gravel Roads Surface Performance Modeling

Transportation Research Record: Journal of the Transportation Research Board, 2007
Twenty gravel road study sections at 10 sites in north-central Wyoming were monitored from September 2005 through June 2006. Windshield or mobile, visual survey ratings of the sections and field measurements were taken weekly. Surfacing gravel samples were collected, and their gradations were determined.

Prediction of Road Marking Performance

Journal of Transportation Engineering, 2007
From the road user's point of view the night-time visibility of road markings during wet conditions is of great importance, and instruments aimed for mobile measurement of the retroreflectivity of road markings are available. However, due to splash from the tires of the measuring vehicle, it is almost impossible to carry out measurements on wet road ...
