The effect of waste logistics on the environmental impact of road transport [PDF]

open access: yes, 2008
Nowadays we should consider the wastes in a much wider sense as an expedient raw material source. From a logistic point of view the fact that the flows of the second raw materials are not constant in the waste logistics systems is a challenge.

Low‐Cost, Large‐Scale Nanoporous Metals by Mechanical Alloying, Oxide Reduction, and Dealloying of Powders

open access: yesAdvanced Engineering Materials, EarlyView.
Powder metal processing provides scalable advantages in nanoporous (np) metal development. Mechanical alloying is used to produce unique precursors for hybrid nanopore formation by oxide reduction and dealloying. As demonstrated in np Ag, this approach improves process efficiency while promoting smaller ligaments and larger pores, both of which are ...

Innovative Processing of Compacted Waste Aluminum Alloy Powders via Controlled Remelting and Solidification

open access: yesAdvanced Engineering Materials, EarlyView.
This study demonstrates an efficient recycling route for out‐of‐spec AlSi10Mg atomized powders through compaction and arc remelting followed by suction casting. By correlating compaction load, cooling rate, and resulting microstructure, we show that intermediate pressures (50–80 kN) and rapid cooling refine dendrites, reduce porosity, and enhance ...

Attitudes of Czech Drivers to Issue of Drinking and Driving – Development in Time and International Comparisons

open access: yesTransactions on Transport Sciences, 2014
This study deals with attitudes of Czech drivers to the issues of drinking and driving, on the basis of SARTRE (Social Attitudes to Road Traffic Risk in Europe) surveys carried out during 1991 – 2002 in European countries.

Interactions between Molten High‐Silicon Electrical Steels and Carbon‐Bonded MgO Refractories Based on Recyclates

open access: yesAdvanced Engineering Materials, EarlyView.
This study examines how several molten high‐silicon electrical steels interact with both conventional and recycled MgO–C refractories. For this, various immersion experiments are conducted. In addition to infiltration, a number of mechanisms are identified and explained that control the corrosion of the refractory material.

Effect of Shared Planning by Road Transport Firms and Shipping Companies on Performance in the Intermodal Transport Chain: the Case of Ro-Ro Short Sea Shipping

open access: yesEuropean Journal of Transport and Infrastructure Research, 2013
In recent years short sea shipping, and specifically the so-called motorways of the sea, have increasingly become the focus of attention in the area of European Union transport policy. As an intermodal alternative to door-to-door unimodal road transport,

Synthesis of a Novel Thermoresponsive S53P4 Bioactive Glass Extract–Poloxamer 407 Injectable Hydrogels: Assessment of Biocompatibility and Antimicrobial Properties

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates innovative thermoreversible hydrogels derived from S53P4 bioactive glass extracts to aid in the healing of infected diabetic foot wounds. These injectable gels, which gel at body temperature, release beneficial ions and remain stable over time.
