This paper examines the impact of climate change on the bio-economic performance of Bay of Biscay mixed fisheries and explores the capacity of alternative management strategies to cope with these impacts. A dynamic multi-species, multi-class, multi-fleet model is developed and calibrated using available biological, economic and environmental inform...

Phase change materials (PCMs) are promising alternative candidates for a variety of thermal energy storage and related applications. Among the PCMs, alkali carbonates have received particular attention in recent years due to their favourable thermophysical properties at high temperatures. However, the use of such carbonates as PCM requires the unde...
One-step catalytic synthesis of methyl acrylate from methyl acetate and trioxane, with 90.7% yield and 91.8% selectivity, was realized at 10-25 degrees 5. NMR analysis confirmed the ester enolization with generation of [i-Pr2EtN-H](+)[TfO](-) in the presence of i-Pr2EtN and Bu2BOTf, which was affected by solvent and base. The depolymerization of tr...
To fully dispose of/utilize sewage sludge, a process combing hydrothermal pretreatment (HTPT), anaerobic digestion (AD) and pyrolysis was developed and tested at the pilot scale. First, the improvement in sludge dewaterability by HTPT at 180 degrees C for 30 min was verified, and the water content decreased from 85 to 33 wt% after filter pressing. ...
A multi-stage fluidized bed (MSFB) by configuring the distributor with an overflow standpipe between its neighboring stages was developed to couple the powder coal pyrolysis with its resultant char gasification for co-production of tar and syngas. This work succeeded in the smooth operation of MSFB for coal staged conversion. The three modes of cou...
The crystalline structures transition of TiO2, Na8Ti5O14, Na2TiO3 and Na2Ti3O7 during electrochemical deoxidation in CaCl2-NaCl melt were investigated via cyclic voltammetry (CV), constant voltage electrolysis, theoretical analysis and calculation. Both of the reduction potential of Na8Ti5O14, TiO2, Na2TiO3 and Na2Ti3O7 shown in cyclic voltammogram...
Four iron ores including limonite, siderite, hematite and magnetite are examined for their catalytic effects on coal pyrolytic products. Experiments were conducted at a pyrolyzer combined with gas chromatography/mass spectrometry (Py-GC/MS). The results show that limonite has the highest catalytic activity for light aromatic formation as a result o...

Nowadays, highly efficient decomposition of ozone is still technologically challenging, especially in the presence of high humidity levels. In this study, Cu2O/reduced graphene oxide composite (Cu2O/rGO) is in-situ synthesized by reducing a mixed solution of Cu2+ and GO. This developed catalytic system exhibits 100% ozone (20 ppm O-3/air) decomposi...
